Methods: From January 2012 to March 2014, a total of 35 patients with achalasia received POEM at Endoscopic Center in the First Affiliated Hospital of Zhejiang Chinese Medical University. Esophageal dynamics of all patients were evaluated by high-resolution manometry (HRM) system preoperatively and one months after peroral endoscopic myotomy (POEM) the test was repeated. The characteristic of esophageal motility of the two tests were compared. Results: After POEM, lower esophagus sphincter resting pressure (LESP) decreased from 28.94 ± 18.70 to 16.02 ± 5.46 mmHg (P < 0.001) and descend rate was 44.6%. 4-second integrated relaxation pressure (4sIRP) decreased from 27.182 ± 14.636 to 12.222 ± 6.75 mmHg (P < 0.001). LESP decreased from 23.000 ± 18.55 to 12.22 ± 6.75% (P < 0.05). Intrabolus pressure (IBP) decreased from 11.02 0± 5.36 to 4.91 ± 4.55 mmHg (P < 0.001). Distal contractile integral decreased from 2103.43 ± 1960.86 to 810.90 ± 1308.50 mmHg (P < 0.05). Esophageal body distal amplitude (average measurements at 3 cm and 7 cm above the lower esophageal sphincter) decreased from 26.21 ± 19.11 to 19.23 ± 9.74 mmHg (P < 0.05). The variation value of Eckhard score between pre- and post-POEM was correlation with the decline of 4s-IRP (r = 0.372, P = 0.036). After POEM, a small segment of proximal esophageal peristalsis appeared in 2 patients but was below normal level. Conclusions: POEM can improve esophagogastric junction relaxation and affect esophageal body contraction in patients with achalasia, but can not restore normal esophageal peristalsis. Background/Aims: Small intestinal bacterial overgrowth (SIBO) has been implicated in pathogenesis of irritable bowel syndrome (IBS). Rifaximin has emerged as a promising therapy for IBS, acting primarily via eradication of SIBO. There is very limited data concerning recurrence of SIBO after successful antibiotic therapy. We aimed to study frequency and predictors of recurrence of SIBO in patients with IBS after successful treatment with rifaximin. Methods: The study included 78 consecutive patients with IBS (without constipation) affected by SIBO who were successfully treated with oral rifaximin therapy (550 mg three times daily for 2 weeks). SIBO was diagnosed on the basis of glucose hydrogen breath test (GHBT) using 100 gm of glucose after an overnight fast. Patients were retested for GHBT at 3 and 6 months after documentation of GHBT normalization. Frequency and predictors of recurrence of GHBT positivity were evaluated. Results: Of 78 patients, 47 (60.3%) were males. Median age of study subjects was 39 (19-74) years. Fourteen (14/78, 17.9%) and 31 (31/78, 39.7%) patients had recurrence of GHBT positivity at 3 and 6 months, respectively after successful rifaximin therapy. At univariate analysis, age > 60 years, chronic use of proton pump inhibitors (PPIs), peak breath hydrogen concentration prior to rifaximin therapy of > 25 ppm, Bristol stool form score ≥ 5, stool frequency > 14/week, and abdominal bloating at presentation were associated with recurrence of GHBT positivity. At multivariate analysis, chronic use of PPIs (OR, 4.28; 95% CI, 1.29-14.13), older age (OR, 5.17; 95% CI, 1.46-18.29) and Bristol stool form score ≥ 5 (OR, 3.43; 95% CI, 1.05-11.17) were independent predictors of recurrence of SIBO. Conclusions: Recurrence of GHBT positivity was observed in substantial proportion of patients with IBS at 6 months after successful treatment with rifaximin. Chronic use of PPIs, older age, and higher Bristol stool form score were associated with recurrence of SIBO in patients with IBS without constipation. S3 ANMA 2015 India Selected Oral Presentation No. 64 No. 82 Patients With Irritable Bowel Syndrome, Particularly Constipation-predominant Type Have More Methanobrevibacter smithii, Which Is Associated With Higher Methane Production on Lactulose Hydrogen Breath Test An Epidemiological Study on Esophageal Symptoms by Rome III Criteria in an Asian Rural Population: Prevalence and Risk Factors 1 1 1 Mohammed Masudur Rahman, Uday C Ghoshal, Md. Golam Kibria, 2 3 AHM Rowshon, Faruque Ahmed, Nigar Sultana, and Mahmud Hasan 1 Dhaka Medical College, Dhaka, Bangladesh; 2Sanjay Gandhi Postgraduate Institute of Medical Sciences, Lucknow, India; Shaheed Suhrawardy Medical College, Dhaka, Bangladesh; and 3 Bangladesh Medical Research Council, Dhaka, Bangladesh 2 Ratnakar Shukla, Ujjala Ghoshal, Deepakshi Srivastava, Tapan N 1 2 Dhole, and Uday C Ghoshal Departments of 1Microbiology and 2Gastroenterology, Sanjay Gandhi Post Graduate Institute of Medical Sciences, Lucknow, India Background/Aims: Though community studies on gastroesophageal reflux disease are available, data on other functional esophageal symptoms are scanty in Asia. Accordingly, we undertook such a study in a rural Bangladeshi community. Methods: In a door-to-door survey, adult population (> 18 years) living in four villages in Bangladesh were interviewed by trained personnel using Bengali translated and validated Enhanced Asian Rome III and general health questionnaire 28 (GHQ-28). Results: Common esophageal symptoms among 3351 subjects (age 40.41 ± 16.04 years, 1924 [57.4%] female) surveyed included: heartburn (n = 428, 12.8%), globus (n = 49, 1.5%), functional chest pain (n = 41, 1.2%), and dysphagia (n = 26, 0.8%). 524/3361 (15.6%) had at least one functional esophageal symptom (FES). FES were commoner among female than male (338/1924 [17.6%] vs 186/1427 [13%]; P < 0.0001), married than unmarried (438/2678 [16.4%] vs 41/424 [9.7%]; P = 0.001), Muslim than Hindu (382/2220 [17.2%] vs 140/1126 [12.4%]; P < 0.0001), low (less than 6733 taka per month) than higher income family (182/984 [18.5%] vs 342/2026 [14.4%], P = 0.004). GHQ-28 score was higher among subjects with FES than those without (0.94 ± 2.64 vs. 0.4 ± 1.49; P = 0.000) and subjects with EFS more often had high score (> 5) than those without (36/521 [6.9%] vs 74/2809 [2.6%], P < 0.000). Conclusions: Sixteen percent people in rural Bangladesh had at least one functional esophageal symptom, heartburn being the most common; other symptoms like globus, functional chest pain, and dysphagia were uncommon. Female gender, marriage, Muslims religion, and low income were the risk factors for EFS on univariate analysis. Psychological distress as evidenced by high GHQ-28 score was higher among subjects with EFS. Background/Aims: Since Methanobrevibacter smithii (M. Smithii) produces methane in the gut, which delays gut transit resulting in constipation and constipation-predominant irritable bowel syndrome (IBS-C), we evaluated quantity of M. smithii in patients with IBS and healthy controls (HC) and its relationship with levels of breath methane on lactulose hydrogen breath test (LHBT). Methods: Quantitative real-time PCR (qPCR) was performed in fecal samples of 47 patients with IBS (Rome III) and 30 HC for M. smithii. LHBT was performed in 25 of these patients with IBS and 10 HC. Fasting breath methane level ≥ 10 ppm or increase by ≥ 10 ppm above basal after 10-g lactulose ingestion was diagnostic of methane-producer. Results: Of 47 patients with IBS, 20 had IBS-C, 20 had diarrhea (IBS-D), and 7 could not be sub-typed (IBS-U). Number of copies of 16S rRNA of M. smithii was higher among patients with IBS than HC (Log10 4.9, IQR [3.2-6.2] vs 1.9 [0.0-3.3], P < 0.001), particularly among IBS-C than IBS-D (Log10 5.7 [5.1-6.5] vs 3.4 [0.6-6.0], P < 0.001). Of 25 patients who underwent LHBT, 8/12 (67%) with IBS-C were methane-producer compared with 3/13 (23%) with IBS-D (P = 0.047). Quantity of 16S rRNA of M. smithii was higher among methane-producers than non-producers (Log10 6.3 [5.6-7.4] vs 4.0 [1.8-5.8], P < 0.001). Area under curve for breath methane had positive correlation with number of copies of M. smithii among methane producers (Spearman correlation coefficient R = 0.81, P = 0.003). Conclusions: Patients with IBS, particularly constipation-predominant, had higher quantity of 16S rRNA of M. smithii than HC. Breath methane levels on LHBT correlated with quantity of 16S rRNA of M. smithii. S4 ANMA 2015 India Selected Oral Presentation No. 111 Abnormal Intestinal Permeability Induced by Acute Stress: Interaction of Gut Microbiota and Adrenal Gland An-Ni Tsai Institute of Brain Science, National Yang-Ming University, Taipei Background/Aims: Acute and chronic stress increase gut permeability, which lead to visceral hypersensitivity and bacterial translocation. The phenomenon may be accounted for the symptoms attack in the patients with irritable bowel syndrome (IBS) or inflammatory bowel disease. Increased gut permeability would also facilitate an increased serum level of circulating endotoxin and promote systemic inflammation through Toll like receptor4 (TLR-4). TLR-4 is a major mediator in the crosstalk between the innate immune system and the endocrine stress response. Probiotics has been shown to be beneficial for clinical symptoms in IBS patients. Therefore, we first aimed to investigate the impact of acute stress on intestinal permeability and immune-adrenal responses. Secondly, the biological effects of probiotic treatment on intestinal permeability after acute stress were evaluated. Methods: Water avoidance stress was applied as the acute stress model. Measurement intestinal permeability was performed by loading FITC-dextran into small intestine. FITC-dextran concentration was determined from portal vein at 2 hours, 4 hours and 6 hours after water avoidance stress. The protein expression level of TLR4 in adrenal cortex after stress was examined by Western blot. Administrate 9 single-dose of Lacidofil (3 × 10 CFU/mL saline) or Lactobacillus casei 9 (5 × 10 CFU/mL saline) was given through oral gavage immediately after the acute stress. Results: Acute stress led to increased intestinal permeability evidenced by elevated portal concentration of FITC-dextran, which peaked at 6 hours after the stress (P < 0.05). Circulating endotoxin leaking from gut were significantly increased at 2 hours after acute stress (P < 0.05). The time course in the changes of plasma corticosterone and TLR-4 expression in adrenal cortex after stress paralleled with the changes in FITC-dextran concentration, suggestive of a regulatory roles of cortisol and TLR-4 in intestinal permeability. A single-dose of Lacidofil, but not Lactobacillus casei, immediately after WAS reversed the changes in FITC-dextran concentration (intestinal permeability). Conclusions: Acute stress would induce increased intestinal permeability, which might be resulted from the interaction between the immunological responses from gut microbiota and the stress-related endocrine response. Probiotics can reverse the acute stress-induced changes in intestinal permeability. The beneficial effect of probiotics in stress-induced alteration in intestinal permeability is strain-specific. S5 ANMA 2015 India Selected Presidential Poster Presentations ANMA 2015 India Selected Presidential Poster Presentation squeezing showed a significant difference between FI and asymptomatic normal control. Pressurization through the lower anal canal during squeezing maneuver of HRAM might have a key role in determining between continence and incontinence. A prospectively well-designed study based on large numbers of subjects may be warranted to validate its clinical meaning. No. 4 New High-resolution Anorectal Manometry Parameter for Fecal Incontinence on the Basis of a 3-dimensional Integrated Pressurized Volume of Spatiotemporal Plot: Comparison Between the Female Patients With Fecal Incontinence and Asymptomatic Normal Control 1 2 1 Kee Wook Jung, Segyeong Joo, Seung-Jae Myung, Dong-Hoon 1 1 1 1 1 Yang, In Ja Yoon, So Young Seo, Hyun Sook Koo, Hyo Jeong Lee, 1 1 1 Ji-Beom Kim, Jong Wook Kim, Soo Kyung Park, Sang Hyoung Park,1 1 1 1 Kyung Jo Kim, Byong Duk Ye, Jeong-Sik Byeon, and Hwoon-Yong 1 Jung Departments of 1Gastroenterology and 2Biomedical Engineering, Asan Medical Center, University of Ulsan College of Medicine, Seoul, Korea Background/Aims: The conventional anorectal manometry and its parameters in fecal incontinence (FI) have been controversial in the discrimination between patients with FI and asymptomatic normal control. Previously, we reported that integrated pressurized volume (IPV) during balloon expulsion, based on the spatiotemporal plot of a high-resolution anorectal manometry (HRAM), was highly correlated with the success of balloon expulsion test in constipated patients. We aimed to develop new parameters in HRAM using IPV in discriminating between FI and asymptomatic normal control. Methods: From August to November 2013, female patients complaining FI were prospectively enrolled using a validated FI questionnaire. Asymptomatic normal female control more than 50 years old were prospectively enrolled after exclusion of Rome III questionnaires. All of the enrolled patients underwent HRAM using circumferential sensors with 23 channels in 6-cm lengths. Resting and squeezing pressures were then converted to ASCII files and analyzed using a MATLAB program. A 3-dimensional IPV was plotted after transforming the data to a cubic spline interpolation followed by resampling the manometry position at 0.1-cm intervals. Results: After exclusion of overflow FI, 12 patients with FI (mean age 71 ± 6 years) were enrolled. Their conventional and new manometric parameters were compared with 6 asymptomatic normal control (mean age 54 ± 2 years). When compared regarding conventional manometry profiles, there was no significant difference between 2 groups. However, the IPV of lower 2 cm anal canal during squeezing showed a lower tendency in FI group than asymptomatic normal control (395.3 ± 137.3 mmHg · cm · sec in FI vs 578.5 ± 201.7 mmHg · cm · sec in control, P = 0.050). Moreover, the IPV of lower 1 cm anal canal during squeezing was significantly lower in FI group than asymptomatic normal control (466.9 ± 165.8 mmHg · cm · sec in FI vs 697.3 ± 243.6 mmHg · cm · sec in control, P = 0.030). Conclusions: The newly developed IPV of anal canal during S9 ANMA 2015 India Selected Presidential Poster Presentation No. 8 No. 12 Fecal Evacuation Disorder Among Patients With Solitary Rectal Ulcer Syndrome: A Case-control Study Effect of Biofeedback Therapy on Anorectal Physiological Parameters Among Patients With Fecal Evacuation Disorder Atul Sharma, Asha Mishra, and Uday C Ghoshal Abhai Verma, Asha Misra, and Uday C Ghoshal Department of Gastroenetrology, Sanjay gandhi Post Graduate Institute of Medical Sciences, Lucknow, India Department of Gastroenetrology, Sanjay gandhi Post Graduate Institute of Medical Sciences, Lucknow, India Background/Aims: Data on frequency of fecal evacuation disorder (FED) among patients with solitary rectal ulcer syndrome (SRUS), hitherto an enigmatic condition, are scanty. Moreover, most such studies had limitations due to small sample size and lack of inclusion of healthy controls (HC). Methods: Forty patients with SRUS underwent symptom assessments, sigmoidoscopy, anorectal manometry, defecography, and balloon expulsion test (BET); endoscopic ultrasound (EUS) of anal sphincter complex was performed in a subgroup. Physiological tests (anorectal manometry and BET) were also performed in 19 HC. Results: Patients with SRUS (26/40 male, age 37 [18-80] years) more often had FED than HC (10/19 male, age 43 [25-72] years) as shown by weight needed to expel the balloon (300 [0-700] g vs 100 [0-400] g; P = 0.006), a trend towards abnormal BET (need of > 200 g weight for expulsion) (21/40 [53%] vs 5/19 [26%], P = 0.058) and impaired anal relaxation (14/40 [35%] vs 2/19 [10.5%]; P = 0.040). Using Rome III criteria, most patients with SRUS reported having chronic constipation (36/40 [90%]) in spite of having normal (Bristol stool type IV, 21/40 [53%]) and diarrheal (types V, VI, and VII; 6/40 [20%]) stool forms (Asian classification). 17/40 [43%] patients with SRUS had functional defecation disorder (Rome III criteria). Patients with SRUS with abnormal BET had thicker internal anal sphincter than those without (3.4 [3.9-7] mm vs 2.8 [2-4] mm; P = 0.010). Conclusions: FED was commoner among patients with SRUS as evidenced by abnormal BET and sphincter relaxation. Those with abnormal BET had thicker internal sphincter on EUS than those without. Background/Aims: Fecal evacuation disorders (FED) are common among patients with chronic constipation presenting to tertiary care centers. Though biofeedback therapy is effective in relieving symptoms in these patients, there is limited data on improvement in physiological parameters after such treatment. Therefore, we evaluated efficacy of biofeedback in improving anorectal physiological parameters among patients with FED. Methods: Consecutive patients with FED (diagnosed in symptomatic patients based on defecography, balloon expulsion test [BET], and anorectal manometry) referred to Gastrointestinal Pathophysiology and Motility Laboratory of a large university hospital from August 2012 to July 2014 were included. Anorectal manometry parameters such as basal and squeeze pressures, residual sphincter pressure during attempted defecation and balloon expulsion test parameters were evaluated before and after biofeedback therapy (2 sessions per day for 2 weeks). Results: Of 29 patients (median age 48 years, range 19-76, 24 [82%] male), defecography and BET and was abnormal in 22/26 (84%) and 25/29 (86%). Pre and post-biofeedback manometric parameters (median and range) were as follows: basal pressure 75 (52-128) vs 67 (53-102), P = 0.045; squeeze pressure 146 (75-248) vs 140 (81-246); P = 0.900; residual anal sphincter pressure during attempted defecation 106 (52-148) vs 85 (37-182); P = 0.020; weight needed to expel intra-rectal balloon during BET 500 (0-700) vs 200 (0-700); P = 0.010. Dyssenergia and BET got corrected in 19/29 (65%) and 14/25 (56%) patients after biofeedback. Conclusions: Successful biofeedback therapy improves anorectal physiological parameters. S10 ANMA 2015 India Selected Presidential Poster Presentation No. 13 No. 22 Influence of Obesity on the Prevalence of Laryngopharyngeal Reflux Disease Clinical Validation of c-PDR: Methodology for Accurate Non-invasive Detection of Helicobacter pylori Infection Cheol Woong Choi, Hyung Wook Kim, Dae Hwan Kang, Su Bum Park, Su Jin Kim, Hyeong Seok Nam, Dong Ku Kang, and Ja Jun Goo 1 2 2 Suman Som, Sunil B Daschakraboty, Sujit Chaudhuri, and Manik 1 Pradhana Department of Internal Medicine, Pusan National University Yangsan Hospital, Yangsan, Gyeongsangnamdo, Korea 1 Department of Chemical, Biological and Macromolecular Sciences, S.N. Bose National Center for Basic Sciences, Salt Lake, India; and 2Department of Gastroenterology, AMRI Hospital, Salt Lake, India Background/Aims: Laryngopharyngeal reflux disease (LPRD) is a variant of Gastroesophageal reflux disease (GERD) that affects the larynx and pharynx. The aim of this study was to examine the association between obesity and LPRD as well as GERD. Methods: We conducted a cross-sectional study of consecutive patients undergoing ambulatory 24-hour dual-probe pH monitoring from July 2003 to December 2006. The association between body mass index (BMI) and parameters about LPRD was examined in univariate and multivariate analyses. Results: A total of 769 patients (307 men and 462 women; mean age 50.7 years) were finally enrolled. Most variables showing GERD was higher in the obese patients than the patients with normal BMI. There was no difference in all the variables showing LPRD according to the BMI. After adjustment for age, sex, alcohol intake and smoking, obese patients demonstrated an about 2-fold increase in risk of GERD compared with patients with normal BMI (OR, 1.9; 95 CI, 1.3-2.9), but overweight patients did not demonstrate increased risk of GERD (OR, 1.2; 95 CI, 0.8-1.7). Both obese patients and overweight patients did not demonstrated increased risk of LPRD compared with patients with normal BMI (OR, 1.1; 95 CI, 0.8-1.7; and OR, 0.9; 95 CI, 0.6-1.3, respectively). Conclusions: Obesity is not associated with LPRD while it is associated with GERD. Background/Aims: Helicobacter pylori is a common and important human pathogen and the primary cause of peptic ulcer disease and gastric cancer. Currently H. pylori infection is detected by both invasive and non-invasive way but the diagnostic accuracy is not up to 13 the mark. To set up an optimal diagnostic cut-off value of C-urea breath test to detect H. pylori infection and evaluate a novel c-PDR methodology to overcome of inconclusive grey zone. Methods: All 83 subjects first underwent upper-gastrointestinal endoscopy followed by rapid urease test and histopathology and depending on these results we classified 49 subjects as H. pylori positive and 34 negative. After an overnight fast patients are taken 4 gm of citric acid in 200 ml water solution and 10 minute after ingestion of the test meal a baseline exhaled breath sample was collected and thereafter 13 an oral dose of 75 mg C-Urea dissolved in 50 ml water was given and breath samples were collected upto 90 minute for 15 minute intervals and analysed by laser based high precisional cavity enhanced spectroscopy. 13 Results: We studied the excretion kinetics of C isotope enrich13 ment (expressed as δDOB C ‰) of exhaled breath samples and found maximum enrichment around 30 minute of H. pylori positive patients, it is due to the acid mediated stimulated urease enzyme activity and maximum acidification happened within 30 minute but no such significant isotopic enrichment observed for H. pylori negative individuals. Using Receiver Operating Characteristic (ROC) curve 13 an optimal diagnostic cut-off value, δDOB C ‰ = 3.14 was determined at 30 minute exhibiting 89.16% accuracy. Now to overcome 13 grey zone problem we explore percentage dose of C recovered per 13 13 hour, ie, C-PDR (%/hr) and cumulative percentage dose of C recovered, ie, c-PDR (%) in exhaled breath samples for the present 13 C-UBT. We further explored the diagnostic accuracy of 13C-UBT by constructing ROC curve using c-PDR (%) values and an optimal cut-off value was estimated to be c-PDR = 1.47 (%) at 60 minute, exhibiting 100% diagnostic sensitivity , 100% specificity and 100% ac13 curacy of C-UBT for detection of H. pylori infection. We also elucidate the gastric emptying process of present 13C-UBT for H. pylori positive patients. The maximal emptying rate found at 36 minute and 13 half empting time of present C-UBT was found at 45 minute. Conclusions: The present study exhibiting the importance of S11 ANMA 2015 India Selected Presidential Poster Presentation c-PDR methodology to overcome of grey zone problem in 13C-UBT for accurate determination of infection without any risk of diagnostic errors and making it sufficiently robust and novel method for an accurate and fast non-invasive diagnosis of H. pylori infection for large scale screening purposes.

However, a cohort of FD patients who 1 overlap EPS and PDS is reported. Moreover, role of delayed gastric emptying in pathogenesis of FD is considered to be limited. The aim of this study was to investigate relationship between sub-classification of functional dyspepsia and gastric emptying. Methods: The 58 FD patients who fulfilled Rome III criteria at a single tertiary care center from December 2012 to August 2014 and 39 healthy volunteers as a control group were enrolled this study. Patients and control group were measured gastric emptying using 13 C-acetate breath test. The point of maximum gastric emptying (Tmax) was evaluated. Because average Tmax in control group was 43.2 ± 16.1 minutes, we defined Tmax more than 60 minutes as delayed gastric emptying. Results: The 58 FD patients were sub-classified into an EPS group (n = 9, 15.5%), PDS group (n = 14, 24.1%), and EPS + PDS group (n = 35, 60.3%). Compared with control group, Tmax in EPS group and PDS group did not changed. However, Tmax in EPS + PDS group was significantly delayed. Moreover, compared with control group, ratio of patients who presented delayed gastric emptying in EPS group and PDS group did not changed. However it in EPS + PDS group was significantly high. Conclusions: FD patients who had both of EPS and PDS symptoms presented delayed gastric emptying. Reference 1. Matsuzaki J, Suzuki H, Asakura K, et al.

S12 ANMA 2015 India Selected Presidential Poster Presentation No. 26 No. 32 Corticotropin-releasing Factor Impairs Tight Junctions by Mediating F-actin in Irritable Bowel Syndrome The Effect of 5-Hydroxytryptamine 4 Receptor Agonist, YKP10811 on Postoperative Ileus in Guinea Pig Li Meng, Lu Bin, Wang Xiaoteng, and Hu Yue Yoo Jin Lee, Young Hoon Youn, Zahid Hanssen, Min Joo Im, and Hyojin Park First Affiliated Hospital of Zhejiang Chinese Medical University, Hangzhou, China Department of Internal Medicine, Gangnam Severance Hospital, Yonsei University College of Medicine, Seoul, Korea Background/Aims: Corticotropin-releasing factor (CRF) plays an important role in the establishment of irritable bowel syndrome (IBS). Increased colonic paracellular permeability mainly regulated by tight junctions (TJs) is associated with IBS-like symptoms. The present study aimed at determining the effect of CRF on TJs. Methods: IBS rat model was established by acute restraint stress which underwent abdominal withdrawal reflex to evaluate visceral sensitivity. According to experiments, Double-labeling immunofluorescence and Western-blot were used to determine the ultrastructure and expression of F-actin, claudin-1, and zonula occludens-1 (ZO-1) in colon mucosa. In vitro, T84 cells were treated with different concentration of CRF. Double-labeling immunofluorescence was used to determine the expression of CRF-R1/R2 on the surface of T84, Western-blot and QPCR were used to analyze the effect of CRF on the expression of F-actin, claudin-1, and ZO-1. Results: In animal experiment, visceral sensitivity was significantly higher in IBS group. The expression of F-actin in colonic mucosa were higher than those in control group, while the expression of claudin-1 and ZO-1 were relatively lower. F-actin filament dissolution and condensation accompanied by redistribution and/or fragmentation of ZO-1 and claudin-1 were detected by double-labeling immunofluorescence. CRF receptors (CRF1 and CRF2) exist on the surface of T84. 10 nM CRF caused a significant rise of F-actin, which were associated with a marked reduction of ZO-1. Conclusions: Our findings indicate that CRF may induce colon epithelial barrier dysfunction through changes in TJ proteins by mediating F-actin. These findings might provide new insights for the pathophysiology of IBS and clinical treatment. Background/Aims: Postoperative ileus (POI) is defined as inhibition of gastrointestinal (GI) motility after abdominal surgery that is associated with patient’s morbidity and prolonged hospitalization. YKP10811 (SK biopharmaceuticals, Daejeon, South Korea) is selective 5-hydroxytryptamine 4 (5-HT4) receptor agonist which is known to have an intestinal prokinetic activity. The aim of this study was to investigate the effects of 5-HT4 receptor agonists including YKP10811 and prucalopride on a POI model of guinea pig. Methods: The experimental of POI in adult male guinea pigs was created by laparotomy, gentle manipulation of the cecum for 60 seconds, and closure by suture. Upper GI transit was measured by the migration of charcoal from the pylorus to the most distal part. Colonic transit was indirectly assessed via measurement of weight and numbers of fecal expulsion every hour for 5 hours after administration of various doses of YKP10811 and prucalopride. Results: Charcoal transit assay showed that both YKP10811 and prucalopride can significantly accelerate delayed in upper GI transit in a dose-dependent manner. In fecal pellet output assay, the number and weight of fecal pallets were slightly increased by prucalopride (dose above 10 mg/kg) and YKP10811 (dose of 1- and 3-mg/kg). Conclusions: Both prucalopride and YKP10811seems to have beneficial effects to hasten upper and lower GI transit in the POI model. YKP10811 might be used as a potential therapeutic drug for POI. S13 ANMA 2015 India Selected Presidential Poster Presentation No. 39 No. 41 Reduction of Hydrogen Sulfide Synthesis Enzymes in Esophagus of Patients With Achalasia Long-term Outcome of Peroral Endoscopic Myotomy in Achalasia Cardia Based on The Sub Types Lili Zhang, Wei Zhao, Zhongqing Zheng, Tao Wang, Chunshan Zhao, Guojian Zhou, Hong Jin, and Bangmao Wang Rakesh Kalapala, Pankaj Shrimal, Mohan Ramchandani, Santosh Darisetty, and D Nageshwar Reddy Department of Digestive Diseases, General Hospital, Tianjin Medical University, Tianjin, China Department of Medical Gastroenterology, Asian Institute of Gastroenterology, Hyderabad, India Background/Aims: The etiology of achalasia was not clear, and there was considerable evidence that the lower esophageal sphincter (LES) dysfunction was due to lack of inhibitory transmitter. Recent studies suggested that hydrogen sulfide (H2S) may act as an inhibitory transmitter in gastrointestinal tract. The aim of the study was to investigate whether the synthesis of endogenous H2S was altered in LES and other parts of esophagus of achalasia patients undergoing peroral endoscopic myotomy (POEM). Methods: Tissue samples in cardia, LES, 2 cm above LES, and 4 cm above LES were obtained from achalasia patients undergoing POEM. And tissue samples in LES from esophageal neoplasia patients undergoing esophagomyotomy were also obtained as controls. The expression of cystathionine--synthase (CBS) and cystathionine-lyase (CSE) in LES were compared between achalasia patients and esophageal neoplasia patients by immunohistochemical staining. In addition, the expression of CBS and CSE were also compared among the different parts of esophagus in patients with achalasia. Results: Both CBS and CSE could be detected in biopsy from achalasia patients and controls. Compared with controls, the expression of CBS and CSE in LES of achalasia patients was significantly reduced (P < 0.05). There was significant difference between the number of CBS and or CSE positive cells in different parts of esophagus in achalasia patients (P < 0.05). Conclusions: H2S synthesis enzymes, existed in human esophagus and the expression of CBS and CSE was reduced in patients with achalasia. Background/Aims: Achalasia cardia (AC) is a primary esophageal motility disorder commonly treated with endoscopic pneumatic dilatation or surgical myotomy. Peroral endoscopic myotomy (POEM) is a safe and effective treatment for AC with significant symptom relief and improvement in objective outcome. Methods: Fifty-one patients with AC (Type I/II/III) who underwent POEM at our institute between March 2013 and April 2014 were included. Pre and post operative symptoms were quantified by Eckardt’s score. Objective tests (High-resolution manometry and timed barium esophagogram) were done pre and post operatively at 6 months. Results: Male: female = 31:20, mean age 70 ± 38 years, SD 14.5. The pre and post POEM values at 6 months are as follows: mean procedure time is 112 minutes. Eckardt’s score: mean-7.3/0.62, SD-1.87/ 0.63, P < 0.001. HRM: integrated relaxation pressure: mean-18.5/ 9.86, SD-2.48/2.14, P < 0.001. Lower esophageal sphincter pressure: mean-46.9/23.2, SD-21.0/14.6, P < 0.001. All patients had improvement on timed barium esophagogram post POEM. Type II and III had a better outcome with POEM compared to type I patients. Conclusions: POEM is feasible, safe and effective technique for treatment of AC. This is the first study to describe the outcome and efficiency of POEM based on types of AC. S14 ANMA 2015 India Selected Presidential Poster Presentation No. 63 No. 66 Genetic Chararecterization of Cryptosporidia in Patients With Hematological Malignancies and Human Immunodeficiency Virus Infection Reduction of Breath Methane Using Rifaximin Shortens Colon Transit Time and Improves Constipation: A Randomized Double-blind Placebo Controlled Trial 1 1 1 1 Ujjala Ghoshal, Prabhat Ranjan, Asmita Dey, V Misra, Bikas 2 3 4 Agarwal, S Nityanand, and Uday C Ghoshal Uday C Ghoshal, Deepakshi Srivastava, and Asha Misra Department of Gastroenterology, Sanjay Gandhi Postgraduate Institute of Medical Sciences, Lucknow, India Departments of 1Microbiology, 2Immunology, 3Hematology, and 4 Gastroenterology, Sanjay Gandhi Postgraduate Institute of Medical Sciences, Lucknow, India Background/Aims: High methane by the methanogenic flora in the gut may reduce gut transit causing chronic constipation (CC). Reducing methane with antibiotic directed against methanogens may accelerate colon transit improving CC. Accordingly, we studied the effect of treatment with non-absorbable antibiotic, rifaximin, on patients with slow transit CC associated with high methane production. Methods: Bristol stool forms, frequency, colon transit time (CTT; 20 markers each at 0, 12, and 24 hours, radiograph at 36 and 60 hours) and breath methane (lactulose hydrogen breath test [LHBT]) were evaluated in 23 patients with CC (Rome III); frequency of methane production was compared with 68 non-constipating irritable bowel syndrome. Methane producing CC (basal breath methane > 10 parts per million (PPM) and/or post-lactulose rise > 10 PPM above basal) were randomized (double-blind) to receive either rifaximin or placebo (thrice daily for 14 days). Bristol stool forms, frequency, breath methane and CTT were recorded after treatment. Results: Patients with CC more often tended to be methane producers (13/23 [56.5%] vs 25/68 [36.5%]; P = 0.070) and had higher area under curve (AUC) for methane (2415 [435-23580] vs 1335 [0-6562.5], P = 0.021) than non-constipating IBS. Eight out of thirteen (61.5%) methane producers and 5/10 (50%) methane non-producers had abnormal CTT (markers retained at 36 hours: 53 [0-60] vs 19 [8-56], P = 0.062; at 60 hours: 16 [0-57] vs 13 [3-56], P = 0.877). Of 13 methane producers, 6 (46.2%) were randomized to receive rifaximin and 7 (53.8%) to placebo. After 1 month, AUC for methane was lower among patients on rifaximin (6697.5 [1777.523580] vs 2617.5 [562.5-19867.5], P = 0.005) than those on placebo (3945 [2415-12952.5] vs 3720 [502.5-9210, P = 0.118). CTT normalized in 4/6 (66.7%) on rifaximin (markers retained at 36 hours: 54 [44-57] vs 36 [23-60], P = 0.05; at 60 hours: 45 [3-57] vs 14[11-51], P = 0.090) but did not normalize in anyone on placebo (P = 0.020) (markers retained at 36 hours: 31 [0-60] vs 25 [0-45], P = 0.078; at 60 hours: 6 [0-54] vs 12 [0-28], P = 0.200). Weekly stool frequency (before treatment: 3 [1-9] vs after treatment: 7 [1-14], P = 0.05) and forms (type 1: 2/6 [33.3%], type 2: 1/6 [16.6%], type 3: 3/6 [50%] vs type 1: 1/6 [16.6%], type 3: 3/6 [50%], type 4: 1/6 [16.6%], type 5: 1/6 [16.6%]) improved with rifaximin than with placebo (7 [3-21] vs 7 [1-14], P = 0.080 and type 1: 1/7 [14.3%], type BackgroundAims: Cryptosporidiosis is a protozoan parasitic disease that commonly causes diarrhea in immunocompromised patients. Till date, there is no study on genotyping of cryptosporidium from patients with hematological malignancies (HM). Therefore, we aimed to study, (1) frequency of cryptosporidiosis in patients with HM and human immunodeficiency virus (HIV). (2) genetic characterization of cryptosporidium in HM and HIV patients. Methods: Eight hundred and ten stool samples of 301 patients were examined by stool microscopy using modified acid fast staining and Enzyme linked immunosorbent assay was performed to detect their specific antigen. Polymerase chain reaction coupled with restriction fragment length polymorphism (RFLP) was used for the species detection. Results: Twenty-four of 301 (8%) patients were positive for cryptosporidium infection by kinyoun staining of which 19/177 (10.7%) were HIV patients and 5/124 (4%) were HM patients. Cryptosporidium was more often detected in patients with diarrhea than those without diarrhea (17/112 [15.2%]; 7/189 [3.7%], P = 0.002). Infected patients presented with acute diarrhea (> 3 loose stools per day for < 2 weeks; 4/24 [16.6%]), chronic diarrhea (> 4 loose stools per day > 4 weeks; 7/24 [29%]), persistent diarrhea (> 3 loose stools per day for 2-4 weeks, 6/24 [25%]), abdominal pain 8/24 (33.3%), vomiting 10/24 (41.6%) and fever 18/24 (75%). Based on RFLP analysis, 18/24 (75%) samples were identified as Cryptosporidium hominis and 6/24 (25%) as Cryptosporidium parvum. Conclusions: Cryptosporidiosis is not uncommon in HM and immunocompromised patients. Most of them were presented with diarrhea. And the most prevalent species causing cryptosporidiosis is Cryptosporidium hominis.

No. 78 Frequency and Risk Factors of Dyspepsia in a Rural Indian Population Uday C Ghoshal and Rajan Singh Department of Gastroenterology, Sanjay Gandhi Postgraduate Institute of Medical Sciences, Lucknow, India Background/Aims: Since community studies, scarce in India, would give the best estimates on prevalence of dyspepsia, we undertook such a study in a rural Indian population. Methods: In a house-to-house survey by a trained interviewer using a translated-validated Rome III and hospital anxiety and depression questionnaires, information about demography, socio-economic parameters, diet and symptoms were collected. Results: Of 5415 (2011 census) subjects from 3 villages (Chhataura, Bastibandgawn, and Molanapur, Jaunpur District, UP), 3426 ≥ 18 years were invited to participate of whom 2876 (84%) participated; 2774 participants (age 38.5 ± 18 years, 1573 [56.7%] male) providing complete data were analyzed. Socio-economically (Prasad classification), 14% were in upper, 16% upper-middle, 21% lower-middle, 25% upper-lower, and 24% in lower classes. 2331/2774 (84%) subjects were vegetarian (no food of animal origin), 305 (11%) lacto-vegetarian (vegetarian with cow’s milk), and 138 (5%) non-vegetarian (foods of animal origin). 528 (19%) subjects met Rome III criteria for dyspepsia; 49/528 (9%) had epigastric pain, 141 (27%) post-prandial distress syndromes (EPS and PDS) and 338 (64%) EPS-PDS overlap. On univariate analysis, high intake of aerated drink (OR, 1.4; 95% CI, 1.2-1.7; P < 0.001), tea/coffee (OR, 1.5; 95% CI, 1.1-1.8; P = 0.004), disturbed sleep (OR, 4.7; 95% CI, 3.8-5.8; P < 0.001) and anxiety (feeling of tension and wound up: 460/528 (87%) vs 1468/ 2246 (65%), worry: 451 (85%) vs 1270 (56%), panic attacks: 401 (76%) vs 1058 (47%), feeling of something awful: 375 (71%) vs 930 (41%), P < 0.01) were associated with dyspepsia. Conclusions: One-fifth people in rural India had dyspepsia, particularly EPS-PDS overlap; risk factors included high intake of aerated drinks, tea/coffee, disturbed sleep and anxiety. S16 ANMA 2015 India Selected Presidential Poster Presentation history, there appeared to be significant differences in symptom severity. Patients with more frequent symptoms appear to suffer more severe symptoms. Comparing first time and referral attenders, there was significant difference in severity of epigastric pain/burning. Future clinical trials of FD, should take into account patients’ symptom chronicity. No. 79 Does Chronicity Impact on The Severity of Functional Dyspepsia Symptoms? 1 2 1 Xiao R Gong, Kok-Ann Gwee, Minhu Chen, and William E 3 Whitehead ; Rome ANMA Working Team 1 Department of Gastroenterology and Hepatology, The First Affiliated Hospital, Sun Yat-sen University, Guangzhou, Guangdong, China; 2 Department of Medicine, Yong Loo Lin School of Medicine, National University of Singapore, Singapore; and 3Department of Gastroenterology, Sanjay Gandhi Postgraduate Institute of Medical Sciences, Lucknow, India Background/Aims: Patients with functional gastrointestinal disorders are defined as having chronic symptoms, and the current Rome criteria requires patients to have symptom onset at least 6 months before. An early study of IBS suggests that patients with 6 months symptoms have more severe symptoms than those who are first time attenders. Aim of this study is to assess the impact of chronicity on severity of functional dyspepsia (FD) symptoms. Methods: Patients presented with dyspepsia symptoms such as postprandial fullness and epigastric pain or burning in last 3 month or longer were enrolled to evaluate the severity of symptoms (1, very mild, 2 mild; 3, moderate; 4, severe; and 5, very severe). The frequency of symptoms (1, less than one day a month; 2, one day a month; 3, two to three days a month; 4, one day a week; 5, more than one day a week, and 6 every day) and previous treatment were also recorded. Patients with no treatment before were classified as first attender, thus those had previous treatment were referral patients. Results: A total of 993 patients (415 male, 578 female) with epigastric pain or burning were enrolled, including less than 6 months (n = 302, 30.4%) and 6 month or longer (n = 691, 69.6%). There were significant correlation between the duration and severity of symptoms 2 (Linear by linear χ = 35.003, P < 0.001). There was also significant correlation between frequency and severity of symptoms. (Linear by 2 linear χ = 117.334, P < 0.001; rs = 0.338, P = 0.029). Among those patients, 163 (16.4%) were first time attenders and 830 (83.6%) were referral attenders. The severity of symptoms was significantly different between the 2 groups (Z = −2.188, P = 0.029). Similarly, a total of 963 patients (384 male, 579 female) with postprandial fullness were enrolled, including less than 6 months (n = 280, 29.1%) and 6 month or longer (n = 683, 70.9%). There was significant correlation between the duration and severity of symptoms (Linear by linear 2 χ = 42.559. P < 0.001; rs = 0.204, P = 0.031). There was also significant correlation between frequency and severity of symptoms. 2 (Linear by linear χ = 74.169, P < 0.001; rs = 0.269, P = 0.031). However, the severity of symptoms was not significantly different between first time attenders (n = 163, 16.8%) and referral attenders (800, 83.1%) (Z = −1.026, P = 0.305) in patients with fullness.

Methods: In a door-to-door survey, adult subjects (> 18 years) living in four villages in Bangladesh (Charcharia, Chatia, and Churain of Dhaka District; Kharrah of Munshiganj district) were interviewed by trained personnel using Bengali translated and validated Enhanced Asian Rome III and General Health Questionnaire 28 (GHQ28). A binary method was used to categorize responses (none and sometimes as 0 and often or almost always as 1). Results: 3351/3559 subjects (94.15%, age 40.41 ± 16.04 years; 1924, 57.4% female) responded. 35/3351 (1.04%) fulfilled Rome III criteria for FC. FC was commoner among female than male (28/1924, 1.5% vs 7/1427, 0.5%, P = 0.004) and among subjects 55 years or older than younger (13/710, 1.8% vs 22/2636, 0.8%; P = 0.035). FC was commoner among lower family income group (≤ 6733 taka/month, Kuppuswami) than higher (20/984, 2% vs 15/2367, 0.6%; P = 0.001) and lower education (≤ 5 standard vs more: 20/1798, 1.1% vs. 10/1553, 0.6%; P = 0.040). Common symptoms among FC subjects were: straining (21/35, 60%), incomplete evacuation (14/35, 40%), anorectal obstruction (12/35, 34.2%), manual maneuvers (8/35, 22.8%) and lumpy or hard stool (Bristol type I and II; 7/ 35, 20%). Only 4/35 (11.4%) subjects with FC passed less than stools/ week. 20/35(57.1%) subjects with FC had associated uninvestigated dyspepsia, all of whom had post-prandial distress syndrome (PDS). GHQ-28 score was higher among subjects with FC than those without (2.63 ± 4.53 vs 0.49 ± 1.67; P = 0.009) and was more often abnormal (≥ 5: 9/35, 25.7% vs 101/3295, 3.1%, P = 0.000). Conclusions: FC, though not prevalent, was commoner among female, older age, low income and lesser educated group in rural Bangladeshi population. FC subjects had higher psychological stress and overlap with PDS. A stool frequency of less than 3 per week was uncommon and only 20% had Bristol stool type I and II stool. Background/Aims: The development-processes by regional socio-cultural adaptation of an Enhanced Asian Rome III Questionnaire (EAR3Q), a cultural adaptation of the Rome III Diagnostic Questionnaire (R3DQ), and its translation-validation in Asian languages are presented. As English is not the first language for most Asians, translation-validation of EAR3Q is essential. Hence, we aimed to culturally adapt the R3DQ to develop EAR3Q and linguistically validate it to show that the EAR3Q was able to allocate diagnosis according to Rome III criteria. Methods: After EAR3Q was developed by Asian experts by consensus, it was translated into Chinese, Hindi-Telugu, Indonesian, Korean and Thai, following Rome Foundation guidelines; these were then validated on native subjects (healthy [HS, n = 60], and patients with irritable bowel syndrome [IBS, n = 59], functional dyspepsia [FD, n = 53], and functional constipation [FC, n = 61]) diagnosed by clinicians using Rome III criteria, negative alarm features and investigations. Results: Experts noted words for constipation, bloating, fullness, and heartburn, posed difficulty. The English back-translated questionnaires demonstrated concordance with the original EAR3Q. Sensitivity and specificity of the questionnaires were high to diagnose respective functional gastrointestinal disorders (FGIDs) (gold standard: clinical diagnoses) in most except Korean and Indonesian languages. Questionnaires often uncovered overlapping FGIDs. Test-retest agreement (Kappa) values of the translated questionnaires were high (0.7-1.0) except in Korean (0.3-0.5) and Indonesian (0.1-0.4) languages at the initial and 2-week follow-up visit. Conclusions: Though Chinese, Hindi, and Telugu translations performed well, Korean and Indonesian versions did not. Questionnaires often uncovered overlapping FGIDs, which were quite common.

However, the change of the structure and function with aging is not well established in this organ. Thus, we evaluated the change of ICC and nNOS immunoreactive cells in the stomach of F344 rat in four different age groups using immunohistochemistry (IHC) and molecular analysis. Methods: The stomach of Fisher 344 rats at 4 different ages (6-, 31-, 74-week, and 2-year of age) were studied (each group, n = 6). The immunoreactivity of c-Kit and neuronal nitric oxide synthase (nNOS) were quantified after immunohistochemistry (IHC). The c-Kit, nNOS, and stem cell factor (ligand of Kit) mRNA were measured by real-time PCR. C-Kit and nNOS protein were assessed by Western blot. Results: The proportion of c-Kit-positive area of 31-week (P = 0.014), 74-week (P = 0.015), and 2-year (P = 0.005) old rat were significantly decreased compared to 6-week old rat in smooth muscle barrier. In myenteric plexus (MP) layer, the proportion of c-Kit positive area of 74-week and 2-year old rat were significantly declined compared to younger age group (P < 0.005). The proportion of nNOS-positive neuronal cell per total neuronal cell was decreased with aging in smooth muscle barrier, circular muscle, and MP layer (74-week and 2-year vs 6-and 31-week in SMB layer, P = 0.005; 31and 74-week vs 6-week in circular muscle layer, P < 0.005; 2-year vs 6-, 31-, and 74-week, P < 0.005, P =0.019, and P = 0.030; 31-, 74-week, and 2-year vs 6-week in MP layer, P < 0.005). c-kit mRNA expression significantly decreased in the 74-week and 2-year-old rats compared to the 6- (P < 0.05) and 31-week-old rats (P < 0.005). nNOS mRNA expression showed significant decrease in the 74-week compared to the 6- (P = 0.005) and 31-week-old age (P = 0.020). Similarly, stem cell factor mRNA expression of 74-week-old and 2-year-old age rats was significantly lower than that of 6- (P < 0.005) and 31-week-old age (P < 0.005), respectively. The expression of c-Kit protein of stomach showed significant decrease in the 2-year-old age rat group compared to the other aged rat group (P < 0.005) and the expression of nNOS protein of stomach showed significant deS19 ANMA 2015 India Selected Presidential Poster Presentation No. 87 No. 102 The Effects of YH12852 on the Experimental Model of Postoperative Ileus in Guinea Pig Treatment With Proton Pump Inhibitors Only Neutralizes Gastric Acid, but Rarely Effective in Preventing Gastroesophageal Reflux: Preliminary Report of an Ongoing Study Zahid Hussain, Lee Young Ju, and Hyojin Park Department of Internal Medicine, Gangnam Severance Hospital, Yonsei University College of Medicine, Seoul, Korea Arun Karyampudi, Rajan Singh, Vivek A Saraswat, Asha Misra, and Uday C Ghoshal Department of Gastroenterology, Sanjay Gandhi Post-Graduate Institute of Medical Sciences, Lucknow, India Background/Aims: Postoperative ileus (POI) is the transient impairment of gastrointestinal (GI) motility that develops as a consequence of almost every abdominal surgical procedure. The disruption of normal coordinated propulsive motor activity of the GI tract lasts for 2-4 days for conventional surgery, but decrease to as little as ≤ 2 days in the case of laparoscopic surgery. Several studies indicate that POI can lead to significant increase in patient morbidity and hospitalization costs. The aim of this study was to evaluate the effect of new drug YH12852, 5-hydroxytryptamine-4 receptor agonists on the experimental model of post-operative ileus in guinea pig. Methods: Adult male Hartley guinea pigs were used to create experimental model of POI. The guinea pig was anaesthetized by intraperitoneal injection of pentobarbital sodium. Laparotomy was done followed by evisceration and gentle manipulation of the cecum using wet gauze for 60 seconds and closure by suture. After operation, the guinea pigs were treated with different doses (1, 3, 10, and 30 mg/kg) of YH12852 through orogastric cannula. The restoration of upper GI transit was measured using migration of charcoal mixture from the pylorus to the most distal point of migration. The lower GI or colonic transit was indirectly measured in non-fasted guinea pig using fecal pellet output assay. Different doses of YH 12852 were administered 1.5 hours after the anesthesia. The number of fecal pellets and weight were measured and recorded in 1 hour increment for 5 hours. Results: Charcoal transit assay showed that YH12852 accelerate delayed upper GI transit in a dose dependent manner. The percentage of charcoal transit after administration of 1, 3, and 10 mg/kg dose of YH12852 was 28.8, 45.0, and 53.3 (cm) respectively. The highest acceleration of GI charcoal migration was achieved at concentration of 10 mg/kg. The highest dose of 30 mg/kg leads to receptor desensitization and hence decreases in the percentage of charcoal migration compare to 10 mg/kg (48.4 vs 53.3). Similarly, the fecal pellet output assay showed significant effect in accelerating colonic motility at concentration of 10 mg/kg in POI model. Conclusions: This study demonstrated very clearly that the oral administration of YH 12852, 5-hydroxytryptamine-4 receptor agonists restored the delayed upper as well as lower GI transit in a dose dependent manner on experimental model of POI in guinea pig. This drug may serve as a useful candidate for examination in a clinical trial of POI. Background/Aims: Proton pump inhibitors (PPIs) are widely used in treatment of gastroesophageal reflux disease (GERD), a common condition. Based on resolution of heartburn, PPIs have been widely claimed to be highly effective in treatment of GERD. There is limited data on frequency of non-acid volume reflux in patients with GERD while on treatment with PPI particularly in India using 24-hour impedance pH-metry. Hence we present findings from such an ongoing study. Methods: Fourteen patients with GERD underwent 24-hour impedance pH monitoring while on PPI (omeprazole 20 mg once daily and ilaprazole 10 mg once daily, n = 7 patients each) to evaluate mean gastric pH, % time gastric pH below 4, mean esophageal pH, % time esophageal pH below 4, % time non-acid gastroesophageal liquid reflux and frequency of diagnosis of abnormal gastroesophageal reflux on pH-metry and impedance monitoring. Results: Of 14 patients (median age 42 years old, range 22 to 63, 50% male) median of mean gastric pH was 3.46, range 0.69 to 5.53, median of % time of gastric pH below 4 was 61.0%, range 10.7 to 98.3 and median of mean esophageal pH was 6.09, range 5.38 to 6.81. During 24-hour pH-metry, of 14 patients, 3 (21%) had abnormal 24-hour pH-metry (% time esophageal pH below 4 above 4.1%). During 24-hour impedance monitoring, of 14 patients, 11 (78.6%) had abnormal volume reflux (% time liquid reflux above 1.3%). Conclusions: Though PPI therapy is associated with lack of abnormal esophageal acidification, non-acidic liquid gastroesophageal reflux was present in as high as 78% patients. This suggests need for additional therapeutic options to prevent occurrence of non-acidic volume reflux.

Methods: It was a prospective, observational, single centre study of 50 consecutive patients with SSc who presented to our rheumatology clinic. Clinical profile of all the patients was noted. Thirty-five patients underwent esophagogastroduodenoscopy, 31 underwent esophageal manometry, 37 underwent lactulose breath test to assess orocecal transit time and glucose breath test for detecting small intestinal bacterial overgrowth (SIBO) and 36 underwent gastric emptying scintigraphy to measure gastric emptying time. Results: Skin manifestations were seen in all patients and gastrointestinal involvement was seen in 98% of patients, with common symptoms being regurgitation (78%) and heartburn (76%). In esophagogastroduodenoscopy, esophagitis was seen in 30, of which 3 had candidiasis and 1 had herpes simplex virus esophagitis. Two patients had gastric antral vascular ectasia. Hiatus hernia was noted in 10 patients. Mean lower esophageal sphincter pressure was 16.1 ± 12.7 mmHg with hypotensive sphinctre in 12 patients. Esophageal peristaltic abnormalities (aperistalsis or ineffective peristalsis) were observed in 90% of 31 patients. Gastric emptying was delayed in 10/36 patients. Orocecal transit time was prolonged in 23/37 patients whereas SIBO was noted in 7/37. Conclusions: The GI involvement is common in SSc with esophagus being the most commonly affected. Motility abnormalities make them prone for super added infections esp. Infectious esophagitis and SIBO as observed in the study and should be investigated.

Apart from obvious cases, a considerable proportion is under-recognized. Careful clinical history, digital rectal examination and anorectal high-resolution manometry (HRM) can unearth sphincter dysfunction. We aimed to study the clinical profile and HRM findings in patients with symptoms of fecal incontinence at a tertiary referral center, seen over a period of eight months. Methods: All patients referred to our motility lab with history suggestive of fecal incontinence, were included. A detailed history with emphasis on obstetric history and peri-anal/spinal surgeries, was taken; this was followed by physical examination including digital rectal examination. All patients underwent anorectal HRM (16 channel water perfusion) at our motility lab. Basal and squeeze pressures were recorded. Patients with low squeeze (less than twice that of basal pressures) were diagnosed to have external anal sphincter dysfunction (EASD), and those with low basal (less than 40 mmHg) and low squeeze pressures were diagnosed to have combined (internal and external) anal sphincter dysfunction (CASD). The findings on anorectal endoscopic ultrasonography (EUS) in patients who underwent the same were recorded. Fifty patients without symptoms suggestive of sphincter dysfunction and with normal anorectal HRM, were taken as controls. SPSS version 16 was used for statistical analysis. Results: A total of 41 patients were included in the study. Thirty (73.2%) patients were female with mean age of 41.9 ± 9.5 years and 11 were males (26.8%) with mean age of 49.9 ± 13.3 years. The most common symptom was urge incontinence (97.6%) followed by fecal urgency (63.4%) and straining at stools (31.7%). In addition, 29.3% of patients had complained of fecal soiling and 19.5% had resorted to digital maneuvers for defecation. Out of 28 parous women, 12 had history of prolonged delivery (42.9%), 8 had instrument/assisted delivery (28.5%) and 10 had episiotomies (35.7%); four of these women had undergone pelvic floor repair surgeries. Among the women, other relevant surgeries were fistulectomy and spinal surgery. Among the 11 male patients, 6 (54.5%) had undergone peri-anal surgeries (hemorrhoidectomy, fistulectomy, anal stenosis correction, and rectopexy). On HRM, the mean basal anal sphincter pressure was 43.4 mmHg and Backgournd/Aims: Technique and initial outcome of perineal antropyloric valve transposition to restructure an irreparably damaged or an excised anorectal sphincter has been reported previously. Use of antropyloric valve for total anorectal reconstruction had reasonable outcomes but lacked voluntary control. We hereby report the initial results of patients who underwent gracilis muscle wrapping around the transposed antropyloric valve in an attempt to improve voluntary fecal control. Methods: This study was conducted at a single tertiary care institution. Eight adult patients (7 males and 1 female) with a mean age of 37 years (range 19-50 years) underwent this procedure. Seven patients already had prior anorectal reconstruction with transposed antropyloric valve and one patient with severely damaged anal sphincter complex underwent single stage composite antropylorus transposition with gracilis muscle wrap. The primary outcome measures were anatomical integrity and functional status of the composite graft in the perineum. Results: This procedure was performed in 8 patients. No operative mortality or serious procedure-related morbidity occurred in any patient. The median postoperative resting pressure was 29 mmHg (range 22-38 mmHg) and squeeze pressure was 72.5 mmHg (range 45-267 mmHg). Improvement in the squeeze pressures was clearly evident following surgery, though it couldn't reach the level of statistical significance (P = 0.070). The St. Mark’s hospital incontinence scores significantly improved in all patients and varied between 7 and 9 (P = 0.004). On personal interviews, all patients who underwent this procedure were pleased with result of their surgery. A longer follow-up with a larger sample size is required and quality of life data has not been evaluated in this study. Conclusions: Gracilis muscle wrapping around perineally transposed antropyloric valve improves the voluntary control and overall functional outcomes in a selected group of patients with end-stage fecal incontinence, requiring anal replacement. S25 ANMA 2015 India Selected Poster Presentation mean squeeze pressures was 64.4 mmHg. EASD was diagnosed in 22 (53.7%) patients, while CASD in 19 (46.3%). Mean basal and squeeze pressures in patients with EASD were 55.55 mmHg and 80.6 mmHg and in patients with CASD, were 29.42 mmHg and 45.75 mmHg respectively. The mean basal sphincter pressure of normal controls was 64.5 mmHg and the mean squeeze pressure was 147 mmHg. The mean basal and squeeze pressure of all patients with incontinence (EASD + CASD) was significantly less than that of controls (P < 0.001 both). Three patients had undergone anorectal endoscopic ultrasonography; external anal sphincter defect was confirmed in 2 patients while combined defect was seen in 1 patient. Conclusions: Urge incontinence and fecal urgency are important symptoms of anal sphincter dysfunction, which would have been otherwise managed as diarrhea-predominant irritable bowel syndrome (IBS-D). Prolonged vaginal/assisted deliveries and perianal surgical interventions are important causes for development of anal sphincter damage, and hence a careful history is important. Anorectal HRM helps in the diagnosis of anal sphincter dysfunction and to offer appropriate therapy. No. 7 High-resolution Manometric Profile of Patients With Solitary Rectal Ulcer Syndrome Preethi Mahalingam, Seshadri Venkatesh Parthasarathy, Piramanayagam Paramasivan, Ubal Dhus, Prem Kumar Karunakaran, Revathy Marimuthu Shanmugam, Hariharan Muthuswamy, Sarojini Ashok Parameswaran, Usha Srinivas, Mohan Arumugam Thiravia, Natarajan Murugan, Bharat Kumar Mookiah, and Kallipatti Ramaswamy Palaniswamy Department of Gastroenterology, Apollo Hospitals, Chennai, India Background/Aims: Solitary rectal ulcer syndrome (SRUS) is postulated to be outcome of a combination of pelvic floor dysfunction, obstructed defecation and rectal mucosal ischemia. Symptoms suggestive of dyssynergic defecation are frequently noted in patients with SRUS, if quizzed closely. There are very few studies which have looked into the prevalence of dyssynergic defecation in patients with SRUS. We aimed to study the prevalence of dyssynergic defecation in patients with biopsy proven SRUS, at our tertiary care centre. Methods: Patients, who were diagnosed to have SRUS based on colonoscopy and confirmed on biopsy, over the last 8 month period, were taken as cases. All patients underwent ano-rectal high-resolution manometry (HRM; 16 channel water perfusion) at our motility Lab. Basal anal sphincter pressures and squeeze pressures were measured; the pattern of pressure change on straining and at attempted balloon expulsion was noted. Dyssynergic defecation was diagnosed when patients had absent/inadequate relaxation or paradoxical increase of anal sphincter pressures, in response to straining and balloon expulsion with inability to expel 50 cc balloon and were classified into 3 types. Fifty patients with normal colonoscopy and normal ano-rectal manometry served as controls. All patients who had dyssynergic defecation were suggested bio-feedback therapy. SPSS version 16 was used for statistical analysis. Results: A total of 21 patients with biopsy proven SRUS were studied. Mean age was 20.5 years and 61.9% were females. 90.5 % of patients had sense of incomplete evacuation and strained at stools, 85.7 % resorted to digital evacuation of stools. Peri-rectal bleeding was seen in 87% and pain on defecation in 47.6%. On colonoscopy 13/21 (61.9%) had ulcers, 7/21 (33.3%) had rectal erosions and/or erythema and 1/21 (4.7%) had polypoidal mucosa. 71.4% (15/21) of patients had dyssynergic defecation on HRM. The mean basal pressure in patients was 66 mmHg and mean squeeze pressure was 146.3 mmHg; the values when compared with those of normal controls (64.5 and 147 mmHg respectively), was not statistically significant (P = 0.601 and P = 0.925 respectively). High anal dyssynergic pattern was seen in all patients. Of all the patients only 2 patients came for biofeedback therapy. Conclusions: The prevalence of dyssynergic defecation is 71.4% in patients with SRUS which is higher than in general population. The basal anal sphincter pressures of these patients are not significantly higher than in normal controls. All patients with SRUS would benefit from ano-rectal HRM.

Only 5-10% of patients has organic cause, with Hirschprung disease (HD) as the major one. Anorectal manometry (ARM) is a non-invasive tool to demonstrate recto-anal inhibitory reflex, which is absent in children with HD. There is scant literature on utility of ARM in management of chronic constipation in young children.Aim: The aim of the present study was to evaluate the role of high resolution ARM in young children ≤ 5 years of age with constipation at a tertiary care referral centre. Methods: Consecutive patients ≤ 5 years of age who underwent anorectal manometry for chronic constipation from August 2012 to August 2014 were identified. Demographic data, manometry findings and subsequent outcome were recorded. Results: A total of one hundred and thirty seven cases (mean age 3 ± 1.2 years, 80 [58.3%] boys] were evaluated. Barium enema done elsewhere was reported as suspicious for HD in 40/137 (29%) cases. The mean basal resting pressure was measured 55 ± 20 mm Hg with no difference observed with respect to gender or final diagnosis. Of these 137 cases, 12 (8.7%) had absent rectal anal inhibitory reflex suggestive of HD. Of them, 10/12 cases had absent ganglion cells on rectal biopsy confirming diagnosis of HD and subsequently underwent surgery. All ARM procedures were done under midazolam sedation with no intra or post procedure adverse events. Conclusions: High definition ARM is reliable and safe tool in management of chronic constipation in young children. Background/Aim: Solitary rectal ulcer syndrome (SRUS) is an uncommon chronic benign disorder associated with typical histological features and disturbed defecatory behavior. There is scanty data regarding high-resolution manometric characteristics of this enigmatic anomaly. We aimed to evaluate the clinical profile and manometric features in patients with SRUS. Methods: Twenty-nine patients with biopsy proven SRUS underwent symptom assessment, anorectal high-resolution manometry (HRM) and balloon expulsion test (BET). Fourteen healthy controls (HC) also underwent anorectal physiological tests. HRM was performed using 16-channel anorectal manometry catheter perfused with water using a pneumatically activated manometric pump. Analysis was done using Trace software. Results: Median age of patients (31 years, range 16-47 years) was comparable to controls (32 years, 18-49 years) (P = 0.410). Patient group was similar to HC in gender distribution (female 18/29 [62.1%] vs 9/14 [64.3%], P = 0.880). The median duration of symptoms at presentation in patients with SRUS was 3 (1-7) years. The symptoms at presentation included rectal bleeding (28/29 [96.6%]), constipation (27/29 [93.1%]), straining at defecation (24/29 [82.8%]), feeling of incomplete evacuation (19/29 [65.5%]), digitation to evacuate stools (10/29 [34.5%]), passage of mucus in stools (8/29 [27.6%]), abdominal bloating (6/29 [20.7%]), and tenesmus (5/29 [17.2%]). Anal resting and squeeze pressures were similar in the two study groups, and all the study subjects had normal recto-anal inhibitory reflex (RAIR). Rectal sensory thresholds were lower in patients as compared to HC (P< 0.02). During attempted defecation, dyssynergia was observed in 17/29 (58.6%) patients with SRUS (P < 0.001). Prolonged balloon expulsion time (> 1 minute) was more frequent in the patient group as compared to controls (19/29 vs 1/14, P < 0.001). Conclusions: Rectal bleeding, constipation and straining at defecation were the most frequent symptoms in patients with SRUS. Rectal hypersensitivity, dyssynergic defecation and prolonged balloon expulsion time were the salient abnormalities observed on anorectal physiological testing in SRUS. S27 ANMA 2015 India Selected Poster Presentation No. 11 No. 14 Profile of Anorectal Manometry in Patients With Dyssynergic Defecation Endoscopic Management of Sphincter of Oddi Dysfunction: A Single Center Experience From India Akash Shukla, Megha Meshram, Prashant Dhore, and Shobna Bhatia 1 Department of Gastroenterology, Seth G S Medical College and K E M Hospital, Mumbai, India Background/Aims: Dyssynergic defecation (DD) is a frequently encountered problem in procedure. The clinical features do not often correlate with anorectal manometry (ARM) findings. No data are available from India on the ARM findings in patient with dyssynergic defecation. We prospectively evaluated the ARM findings in patients with DD and their correlation to symptoms. Methods: Sixty conservative patients (43 male, mean age 36.5 years) with dyssynergic defecation were diagnosed by symptoms of obstructed defecation and normal sigmoidoscopy included in the study. Anorectal manometry was performed using Water perfusion (Trace 1.2, Australia) system. Baseline/squeeze sphincter pressures and rectal balloon expulsion were carried out. Based on manometric abnormalities, patients were classified as having Type I-IV dyssynergia. Those patients who could not expel balloon with 50 g weight within one minute were considered as abnormal. Results: Mean age of women was higher (42.5 vs. 36.5 years, P = 0.016. Median frequency of stools was 1/day (range 0.1-8). 10 patients had stool frequency < 1/day. 6 patients had < 3 bowel movements/week. Mean sphincter pressure was 58.8 (14.8) mmHg and squeeze pressure was 113.1(60.0) mmHg. Balloon expulsion was abnormal in 51 patients, and in all patients with bowel frequency < 3/week. Baseline and squeeze pressures were highest in patients with Type I DD (P = 0.039). None of the symptoms correlated with type of DD. Conclusions: Type 1 is the commonest type of defecatory disorder. Only 1 patient with type II was found in our series. Clinical symptoms were not useful for predicting abnormal balloon expulsion test. 1 2 1 3 S K Sinha, J Samanta, A Bhatachraya, R Prasada, A Lal, P K 1 1 1 Siddappa, N Berry, and R Kochhar Departments of 1Gastroenterology, 2Nuclear Medicine, and 3 Radiodiagnosis, PGIMER, Chandigarh, India Background/Aims: Sphincter of Oddi dysfunction (SOD) leads to pancreatobiliary pain, cholestasis, and/or pancreatitis. Management with endoscopic sphincterotomy (ERCP-ES) has been reported mostly from developed countries. The aim of this study was to evaluated the outcome of SOD patients treated with ERCP-ES. Methods: Study included all patients presenting with features of “presumptive” SOD according to modified Milwaukee classification between April 2012 and July 2014. All these symptomatic patients had estimation of pancreatic enzymes and alkaline phosphatase, CT scan and MRI of abdomen. SOD was confirmed by hepatobiliary scintigraphy scan (Sostre score). Patients were treated with endoscopic sphincterotomy (biliary and pancreatic). Results: Eleven patients (7 males, age 36.9 ± 13.5 years) were seen during study period. Five patients (45.5%) had chronic pain abdomen while 6 (54.5%) had history of recurrent acute pancreatitis. Mean Sostre score was 7.3 ± 1. Three (27.3%) were opium addicts. While common bile duct was dilated in all 3, pancreatic duct was dilated in 2 patients. All patients underwent pancreatic and biliary sphincterotomy, pancreatic stent (5 Fr) was placed in 4 (36.4%). Five (45.5%) developed post ERCP pancreatitis (PEP)−2 (18.2%) were moderately severe, rest were mild and all improved with conservative management. During a median follow up of 6 months, 2 (18.2%) patients had recurrence of symptoms. Conclusions: SOD can be effectively managed with ERCP with endoscopic sphincterotomy but is commonly associated with post ERCP pancreatitis. S28 ANMA 2015 India Selected Poster Presentation No. 16 No. 17 Elevated Somatosensory Glutamate-Glutamine Levels in Functional Dyspepsia: Preliminary Magnetic Resonance Spectroscopy Findings Gut Bacterial Infection Does Not Affect Experience-specific Memory 1 Arthur D P Mak, J C Y Wu, D K Yeung, D F Wang, W C W Chu, Y Chan, F Fang, S Lee, and L C W Lam Institute of Digestive Diseases, Department of Radiology and Department of Psychiatry, The Chinese University of Hong Kong, Hong Kong SAR, China 1,2 Cheng-Che Hung, Chia-Fen Tsai, 1,5 Lu 3,4 Ying-Chieh Tsai, and Ching-Liang National Yang-Ming University Background/Aims: In post-prandial distress syndrome (FD-PDS), brain imaging has shown elevated resting activity and impaired structural connectivity between regions involved in homeostatic-interoceptive processes (insula, somatosensory cortex [SSC]) and descending sensory modulation (pregenual anterior cingulate cortex [pgACC]). Excitatory glutamatergic transmission may underlie these changes, but has not been studied on FD-PDS. The aim of this study was to compare the glutamate-glutamine (Glx) concentration of the left insula, SSC and bilateral pgACC between FD-PDS female patients and healthy controls, and assess their correlation with dyspeptic, anxiety and depressive variables. Methods: Adult FD-PDS (Rome III) female patients and age-matched healthy controls were recruited for proton magnetic resonance spectroscopy (1H-MRS). We excluded gastroesophageal reflux disease, irritable bowel syndome, severe medical or psychiatric illnesses, Helicobacter pylori infection, substance abuse, use of psychotropic drugs, NSAID or proton pump inhibitor or drugs affecting gut motility, and presence of metal in the body. 1H-MRS was done with voxels in bilateral pgACC, left Insula, and left SSC. Relative metabolic concentrations of Glx to total creatine + phosphocreatine (Cr + PCr) were computed for cases with chronic recurrent multifocal osteomyelitis (CRMO) ≤ 20%. A standardized questionnaire measured dyspeptic symptom severity (0-4). Depressive (Montgomery Åsberg Depression Rating Scale [MADRS]) and anxiety (Hamilton Anxiety Rating Scale [HAM-A]) symptoms were rated by a trained clinician interviewer. Results: Eighteen FD-PDS (mean age 44.94 ± 9.47 years) female patients were matched with 18 healthy female controls (mean age 44.94 ± 9.86 years). Mean duration of FD-PDS was 11.19 years. FD-PDS subjects had elevated global dyspeptic symptom (0.94 vs 0.32, P < 0.001), HAM-A (17.89 vs 2.17, P < 0.001) and MADRS (5.17 vs 0.56, P = 0.020). FD-PDS subjects had significantly elevated Glx/Cr + PCr in the SSC (17 FD-PDS vs 18 controls included, 1.77 ± 0.22 vs 1.60 ± 0.14, P = 0.020, Cohen’s D = 0.920). No significant differences were observed in the insula or pgACC. In FD-PDS subjects, SSC Glx/Cr + PCr significantly correlated with dyspeptic illness duration (r = 0.580, P = 0.020) but not global dyspeptic symptom severity, HAM-A or MADRS scores. In multivariate analysis, HAM-A but not MADRS scores abolished significance of the between-group differences in Glx/Cr + PCr. Conclusions: Increased excitatory glutamatergic transmission in the left somatosensory cortex was found in FD-PDS, apparently mediated by anxiety and chronicity of dyspepsia. Background/Aims: Gut bacterial infection has been reported to impair 1 memory upon pre-exposure to stress. However, the underlying neuronal mechanisms behind the memory changes are still poorly defined. We tested the hypothesis that gut bacterial infection with stress would affect the neuronal activation in hippocampus upon memory re-exposure. Methods: Evironmental enrichment (EE) was used as a model of contextual experience memory stimuli. The mice were re-exposed to the EE context 4 weeks after the first EE exposure. Experience-specific memory to EE was measured by colocalizaiton of immediately early gene (c-fos, markers for neuronal activity) and BrdU (markers for neurogenesis) in the neurons (NeuN) of dendate gyrus (DG) in hippocampus. The effects of Citrobacter rodentium infection with or without stress on this specific contextual memory were examined. Results: (1) EE significantly enhanced hippocampal neurogenesis + + (increased numbers of BrdU /NeuN cells, P < 0.01) in the DG neurons. (2) Re-exposure to the contextual of the same EE condition for 2.5 to 4 hours would not only significantly induced neural activity + + (c-fos /NeuN ; P < 0.001) but also retrieved an experience-specific + + + memory (BrdU /c-fos /NeuN ; P < 0.05). This phenomenon indicated an enhanced response to a contextual experience memory. (3) + + + The cell counts of BrdU /c-fos /NeuN did not change after C. rodentium infection in combination, no matter with or without stress. Conclusions: Gut bacterial infection, independent of stress, did not to affect the experience-specific contextual memory encoded in adult neurogenesis of hippocampus, suggesting a relatively stable encoding in adult-born neurons during EE-related memory recall.

At least one of these intermediates, serotonin (5-HT) is accepted as a fundamental determinant of gut health and disease (irritable bowel syndrome [IBS]). However, it is increasingly evident that other tryptophan metabolic intermediates produced both by the host and gut microbiome, may play more subtle yet physiologically significant roles in bidirectional communication in the gut-brain axis. Methods: Using co-culture models on intestinal Caco-2 cells and Mass Spectrometry based metabolomics, we demonstrate that specific species of bacteria often reported in small intestinal bacterial overgrowth (SIBO) mediated irritable bowel syndrome (IBS), dysregulate the host tryptophan pathway. Results: The SIBO bacteria modulate production of 5-HT, kynurenine, kynurenic acid, 3-hydroxykynurenine, or quinolinic acid in the colonized epithelial microenvironment. The latter 2 exhibit potent neurotoxic properties. SIBO bacteria also actively modulate host epithelial innate immunity and defensin production. Conclusions: Together these present new insights in the mechanism of SIBO-IBS pathophysiology. Background/Aims: Fructose malabsorption (FM) mimics the symptoms of irritable bowel syndrome (IBS), and its prevalence has rapidly increased because of the frequent use of fructose in food products. However, diagnosing FM in IBS is challenging because of its overlap with small intestinal bacterial overgrowth (SIBO) and the differences among fructose dosage cutoffs that distinguish between FM and normalcy, especially in Asian individuals, in hydrogen breath testing (HBT). We assessed the prevalence of FM by comparing patients with IBS with asymptomatic control individuals after excluding SIBO using the glucose HBT. We also evaluated the effective fructose dosage for HBT. In addition, we assessed the differences between the dietary habits of patients with IBS and asymptomatic control individuals. Methods: From December 2011 until November 2012, patients with IBS were identified using the Rome III questionnaire, and the asymptomatic control individuals were prospectively enrolled in the study. Dietary habits were determined using the food frequency questionnaire and responses were analyzed using a computer-aided nutritional analysis program. After excluding SIBO using the 75-g glucose HBT, the enrolled participants were tested using both the 15- and 25-g fructose HBTs, with an interval of at least 1 week. Results: After excluding SIBO-positive patients and those that dropped out of the study during follow-up (n = 18), 35 patients with IBS (male:female [M:F] = 16:19, mean age 43 ± 14 years) and 35 asymptomatic control individuals (M:F = 18:17, mean age 38 ± 11 years) were enrolled in the study. The 15-g fructose HBT yielded positive results in seven of the 35 (20.0%) patients with IBS and in 2 of 35 (5.7%) asymptomatic control individuals (P = 0.070). The 25-g fructose HBT yielded positive results in 16 of the 35 (45.7%) patients with IBS and in eight of the 35 (22.9%) asymptomatic control individuals (P = 0.040). CAN analysis of the FFQ responses showed no significant differences between the 2 groups in relation to total calorie intakes, and protein, lipid, carbohydrate, and fructose consumption. However, patients with IBS showed a significantly higher mean fiber intake than that of the control individuals (21.24 ± 11.35 g in patients with IBS vs 15.87 ± 7.07 g in asymptomatic control individuals, P = 0.040). Conclusions: Use of the 25-g fructose HBT enabled identification of FM in a significantly higher percentage of SIBO-negative patients with IBS than in asymptomatic control individuals, suggesting that FM is closely correlated with IBS. Education regarding dietary control of foods containing fructose may be useful for the management of patients with IBS. S30 ANMA 2015 India Selected Poster Presentation 13 DOB C‰ values with the profiles of IBS-D patients presenting positive SIBO, indicating HBT often fails to diagnose of SIBO, when patients harbouring possibly “non-hydrogen-production” bacteria or hydrogen consuming bacteria in the small intestine. Moreover, when an individual is just at the acute onset of SIBO or falls within the 13 "grey-zone," the significant level of the statistical analysis of δDOB C‰ measurements was more robust (P < 0.001) compared to the statistical level of histamine H2 measurements (P = 0.240). Finally, the prevalence of SIBO in IBS-D patients from India was found to be 45.7%, suggesting a close association between IBS-D patients and SIBO syndrome. 13 Conclusions: These findings demonstrate that C-GBT is a clinically valid and sufficiently robust alternative non-invasive diagnostic methodology for the accurate evaluation of SIBO in IBS-D patients and is superior to the widely used HBT. No. 21 Non-invasive Diagnosis of Small Intestinal Bacterial Overgrowth in Diarrhea-predominant Irritable Bowel Syndrome Patients Using High-precision Stable 13CO2/12CO2 Isotope Ratios in Exhaled Breath 1 2 2 Gourab Dutta Banik, Sunil B Daschakraboty, Sujit Chaudhuri, and 1 Manik Pradhan 1 Department of Chemical, Biological and Macromolecular Sciences, S.N. Bose National Center for Basic Sciences, Salt Lake, Kolkata, India; and 2 Department of Gastroenterology, AMRI Hospital, Salt Lake, Kolka, India Background/Aims: At present, Hydrogen breath tests (HBT) are widely used for diagnosis of small intestinal bacterial overgrowth (SIBO) in patients with irritable bowel syndrome (IBS). However the conclusions drawn from the studies are controversial and several discrepancies exist in the results as there are numerous intrinsic drawbacks, limitations and pitfalls. The aim of our study was therefore 13 13 3-fold: (1) to develop an alternative C-glucose breath test ( C-GBT) 13 12 methodology by measuring high-precision CO2/ CO2 stable isotope ratios in exhaled breath using an optical cavity-enhanced CO2 isotope analyzer to accurately diagnose SIBO in IBS patients, (2) to evaluate 13 the clinical efficacy of C-GBT for "non-hydrogen-production" individuals and during the preclinical phase or at the acute onset of SIBO and finally, and (3) to explore the prevalence of SIBO in diarrhea-predominant IBS (IBS-D) patients from India and their poten13 tial link assessed by C-GBT. Methods: A total number of 118 IBS-D patients with suspected SIBO diagnosed according to Rome III criteria were selected for 13 C-GBT. Patients ingested the test meal containing 50 mg 13C enriched glucose with 50 g normal glucose dissolved in 250 mL of water. Concentration of hydrogen levels (ppm) and high precision 13 CO2/12CO2 isotope ratio in exhaled breath were measured in every 15 minutes intervals for 180 minutes. Results: In the first series of experiments, the excretion of 13CO2 13 isotopic enrichment, expressed in delta-over-baseline (δDOB) C‰, in exhaled breath samples depleted more in case of IBS-D individuals (n = 25) with suspected SIBO (positive HBT) compared to the IBS-D patients (n = 53) without SIBO (negative HBT). We obtained that 13 there were statistically significant differences of the δDOB C‰ values 13 (P < 0.001) and cumulative percentage dose of C-recovered (P < 0.001) at 45 minutes in breath samples between positive and negative 13 SIBO patients, suggesting C-GBT is an alternative diagnostic tool for detection of SIBO. An optimal diagnostic cut-off level of δDOB13 C‰ ≤ 5.47‰ at 45 minutes is indicative of positive SIBO. In the second series of experiment, a group of (n = 20) IBS-D individual whose HBTs are negative followed the similar excretion profiles of δ S31 ANMA 2015 India Selected Poster Presentation No. 27 No. 28 Gut-directed Hypnotherapy Is Superior to Drug Therapy in the Management of Diarrhea-predominant Irritable Bowel Syndrome: A Randomized Controlled Study Psychological and Dietary Factors Exacerbate Symptoms of Irritable Bowel Syndrome Sivaprasad Punnaveetil and Varghese Thomas Department of Gastroenterology, Government Medical College, Kozhikode, Calicut, India Sandeep Kunhikannan and Varghese Thomas Department of Gastroenterology, Government Medical College, Kozhikode, Kerala, India Background/Aims: Irritable bowel syndrome (IBS) is a chronic disorder without any definite cure. Many treatment options are available, which of all are not satisfactory. We studied the efficacy of placebo, amitriptyline, loperamide, and gut-directed hypnotherapy in diarrhea-predominant IBS (IBS-D) in a randomized controlled trial. Methods: Seventy-three consecutive patients with IBS-D (Rome III) criteria were studied. They received therapy for 6 weeks with either placebo (Group A), amitriptyline 10 mg (Group B), loperamide 2 mg (Group C), or GHT (Group D). Reassessment of pain, bowel frequency, general well being, toilet time per week and quality of life (QOL) were done at 3 weeks, 6 weeks, and 3 months. Results: The baseline characteristics were similar in all groups. Regarding abdominal pain and general well being, short-term benefit was observed in all groups except group A, while long-term benefit was observed only in group D. Average stool frequency was found to be significantly reduced in group D (P = 0.003). Compared to placebo, total toilet time spent for defecation was found to be reduced in all groups. At 6 weeks, the change in QOL was statistically significant in group B and C as against placebo; but this effect was not seen at 3 months. Long-term efficacy and sustained improvement in QOL was observed only in Group D at 3 months (P = 0.004). Conclusions: Gut-directed hypnotherapy is more effective than medical therapy in IBS-D patients. Both loperamide and amitriptyline provided significant relief of symptoms initially and there were no statistically significant difference in the benefits obtained between these drugs. S32 Background/Aims: Irritable bowel syndrome (IBS) is a chronic disorder lasting for many years, but very often the patients seek medical care when they experience exacerbation of symptoms. We analyzed the role of various psychological and dietary factors in the exacerbation of symptoms of IBS. Methods: One hundred consecutive patients with IBS who satisfied the Rome III criteria were enrolled in this cross-sectional study. Patients were evaluated to rule out organic causes. Detailed dietary history was obtained and a questionnaire containing the presumptive stressful life events scale (PSLES) and the hospital anxiety and depression scale (HADS) was utilized. Results: Mean age of the cohort was 30.74 ± 9.31 years. The male to female ratio was 68:32. 62% patients had diarrhea-predominant IBS, 28% had mixed IBS, and 10% had constipation-predominant IBS. Mean stool frequency of diarrhea-predominant IBS patients was 4.5/day versus 1.9/week for constipation-predominant IBS. Mean PSLES score of the patients was 262.21 ± 143.86, indicating high level of stress. Moderate to high scores for anxiety and depression were documented. Higher scores of PSLES, HADS-Anxiety, and HADS-Depression were associated with increased stool frequency. However statistical significance was achieved only for HADS-A scores (P = 0.050). Mean PSLES and HADS-D scores were significantly higher for patients with psychiatric illness (P = 0.007 and P = 0.027 respectively). Majority of subjects (96%) consumed a spicy diet and 67 (69.8%) subjects reported subjective symptomatic improvement after reducing the spices in their diet. Conclusions: High levels of stress, anxiety and depression were noted in patients suffering from IBS. Majority of patients noted relief of symptoms on reduction of spices in their diet. ANMA 2015 India Selected Poster Presentation No. 29 No. 30 Different Distribution and Changes in the Interstitial Cells of Cajal and Neuronal Nitric Oxide Synthase With Age in the Proximal and Distal Colon of F344 Rat Brain-derived Neurotrophic Factor Induce the Plasticity of the Structure and the Function on the Mice Colon Smooth Muscle Cells Nayoung Kim Qilu Hospital, Shandong Province, China Department of Internal Medicine, Seoul National University Bundang Hospital Jing Cao Background/Aims: Brain-derived neurotrophic factor (BDNF) is one member of neurotrophin family of proteins which is known for its effect of neuronal survival, differentiation, migration, and synaptic plasticity in central and peripheral neurons. Some studies have shown that exogenous BDNF stimulate human gut motility in health and constipation. Recently, the positive role of BDNF in gastrointestinal motility has drawn increasing attentions. A mount of studies have shown that BDNF could induce the plasticity of enteric neurons to affect the construction of colon but the study whether BDNF could work on the smooth muscle cells directly is limited. The aim of the present study was to investigate the effects of BDNF on the plasticity of the structure and the function of the mice colon smooth muscle cells. Methods: First, the electron microscopy was used to investigate +/− mice controlled with BDNF+/+ muscular alterations in BDNF mice, and the alpha smooth muscle actin (-SMA) which has been manifested to be related with the contraction of the smooth muscle was measured by Western blotting. Second, the primary mice smooth muscle cells were cultured, and the immunofluorescence staining was used to exam the expression of the high-affinity receptor of BDNF, tropomyosin-related kinase B (TrkB) receptor. Third, BDNF and TrkB antagonists (k252a) was used to intervene the mice smooth muscle cells. The alteration of the mice smooth muscle cells structure was examined by the electron microscopy, the expression of the TrkB receptor, phospholipase C (PLC), and -SMA was examined by 2+ 2+ Western blotting. Finally Intracellular Ca concentration ([Ca ]i) changes in myenteric neurons were monitored using Fluo-3. Results: First, electron microscopy showed ultrastructural damage +/− on the smooth muscle cells of BDNF mice. The cellular borders of SMCs were characterized by multiple bulbous protrusions; the cell bodies contained less myofilaments; and the interstitial gaps between adjacent smooth muscle cells were focally widened. The levels of the -SMA in BDNF+/− mice colon was obviously less than the control group. Second, the colon smooth muscle cells expressed TrkB receptors, which was first time in the world to indicate BDNF could directly mediate the colon smooth muscle cell plasticity by TrkB signal pathway. Third, BDNF could cause the ultrastructural alteration of the colon smooth muscle cells, which is similar to the tissue mentioned above. And the TrkB-PLC signal pathway proteins have changed un2+ der the effect of BDNF. Finally, BDNF could cause the [Ca ]i increasing than the control, and K252a could suppress this phenomenon. Conclusions: BDNF induce the plasticity of the structure and the function on the mice colon smooth muscle cells by TrkB-PLC signal pathway, and then can affect the contraction of the smooth muscle cells. Background/Aims: The disorder of motility such as constipation is a common problem in the elderly. However, the time-course of the effect of aging on colon is not well established. We aimed to investigate the difference of proximal and distal colon and the effect of aging between these two areas of colon in F344 rats. Methods: The morphologic changes of colonic smooth muscle were quantitatively measured using the image analysis system in F344 rats at 4 different ages (6-, 31-, 74-week, and 2-year-old) in the proximal and distal colon (each, n = 6). The immunoreactivity of c-Kit and neuronal nitric oxide synthase (nNOS) in proximal and distal colon were also quantified. Furthermore, for functional study electrical field stimulation (EFS) to circular muscle strips of proximal and distal colon in organ bath was performed in young (31-week) and aged (74-week) F344 rats. Results: The intramuscular fat accumulation significantly increased with age after 31-week-old in both proximal and distal colon. In terms of nNOS distribution the immunoreactivity was significantly higher in the proximal colon than in the distal colon in the submucosal border, circular muscle, myenteric plexus, and longitudinal muscle after 31 weeks (P < 0.05). c-Kit distribution was significantly higher in the distal colon than in the distal colon in the all ages (P < 0.05). c-Kit and nNOS immunoreactivity significantly declined with age (P < 0.05). However, the declination of the c-Kit immunoreactivity was more prominent in distal colon than in proximal colon, but that of nNOS was reverse. During the contractile recording, the spontaneous contractile response in resting state was significantly decreased in distal colon (31 weeks, 6.30 ± 3.16 mN vs 84 weeks, 3.77 ± 2.08 mN) but not in the proximal colon (young, 12.65 ± 7.95 mN vs senescent, 9.14 ± 4.05 mN). Under the non-adrenergic non-cholinergic (atropine + phentolamine) condition, the relaxation was not inhibited by apamin but by L-NG-Nitroarginine methyl ester (L-NAME) (P = 0.000) in the distal colon. Conclusions: There was a difference in terms of density of nNOS and c-Kit between proximal and distal colon. The relative different decrease of interstitial cell of Cajal and nNOS (+) neuronal cells depending on proximal and distal colon in the aged rat might affect intestinal contraction, which could be related with frequent constipation in the elderly. Further molecular study is undergoing. S33 ANMA 2015 India Selected Poster Presentation No. 31 No. 33 Brain-derived Neurotrophic Factor Contribute to Regulation of the Intestine Motility in Functional Constipation Searching for a Definition for Refractory Constipation Tengfei Wang, Xiuli Zuo, Hongbo Ren, Yanbo Yu, Feixue Chen, Han Liu, Chao Liu, Qiujie Zhao, and Yanqing Li 1 Qilu Hospital of Shandong University, Jinan, Shandong, China 1 1 2 Alex Y S Soh, Kewin T H Siah, and Kok-Ann Gwee Department of Gastroenterolgy and Hepatology, National University 2 Health System, Singapore; and Department of Medicine, Yong Loo Lin School of Medicine, National University of Singapore, Singapore Background/Aims: Patients with severe chronic constipation are usually selected for treatments such as biofeedback and surgery if they fail medical treatment. We hypothesise that the definition of refractory constipation is poorly defined, variable and the medical treatment applied may not even have proven efficacy. Methods: We carried out a systematic review of the literature using text word searches on Pubmed, EMBASE and Cochrane for studies that were carried out in the last 10 years. The following search terms were used: Constipation AND (Refractory OR Failed OR Colectomy OR Biofeedback). All abstracts were reviewed and all relevant full texts were retrieved. Studies relating to secondary constipation, faecal incontinence, pediatric studies or studies where the definition for constipation was not mentioned, were excluded. Only those studies reporting chronic constipation or functional constipation were selected. These studies were further scrutinized on how failed medical treatment was defined. Results: PubMed, Cochrane, and EMBASE revealed 99, 24, and 4 results respectively. We excluded 91 studies. 36 relevant studies were reviewed. There was no unifying criterion used to define refractory constipation. We found that refractory constipation was defined in many ways. Some papers used the Rome criteria, or modifications of it, with duration of symptoms ranging from 6 months to 5 years. Some studies also required patients to have failed interventions such as fiber, laxatives, and enemas, while others required patients to undergo investigations such as colonic transit test, imaging or manometry. Only one study described the dose, frequency, and duration of medications tried before being considered as having failed treatment. Conclusions: Refractory constipation is ill-defined with very little studies providing specific details on pharmacological agent, dose and dosing frequency. A large number of studies applied the response to fibre treatment, but given that it is largely ineffective in severe constipation, this is an inappropriate criterion. There is an urgent need to define a validated criterion for refractory constipation. Background/Aims: The manifestations of functional constipation (FC) have the common ground of abnormal gastrointestinal motility and intestinal smooth muscle reconstruction. Brain-derived neurotrophic factor (BDNF) is a membership of neurotropic factor family, which is confirmed to express not only in CNS but also in intestinal nerve plexus and mucosa. In FC patients, the expression of BDNF is reduced compared with the healthy ones. A couple of confirmatory clinical trials have shown the effect of combination human BDNF in promoting the intestine motility and elevating defecation frequents. In this research we investigated the effect of BDNF on intestine smooth muscle cells and its cellular mechanism. Methods: We isolated the primary myenteric neurons rapidly from −/+ knockout C57/BL mice (n = 10, 4 weeks) distal colon of BDNF and wild-type mice (n = 10, 4 weeks), and cultured the neurons with primary intestinal smooth muscle cells as stable co-culture cellular -8 system. Separating this system into group A (treated with 10 M -6 BDNF, 10 minutes), group B (10 M K252a pretreatment, 30 minutes) and the control group (0.9% NS treatment). Calcium imaging 2+ was used to record the cytoplasmic Ca concentration in smooth muscles, and electrophysiological recording in whole cell mode helped to shown ion flux and the excitability change. Results: The primary myenteric neuron-smooth muscle cells co-culture system could maintain the morphological stability and physiological activity at 16-24 hours. (1) In calcium imaging recording, there was an increasing calcium transient in the group A SM cells of knockout mice (F/F0, P < 0.05, n = 6) and wild-type group 2+ (F/F0, P < 0.05, n = 9). Meanwhile the range of Ca concentrate change was greater in knockout mice than wild-type ones (P < 0.05). These calcium transient could be suppressed by BDNF-trkB signal -6 inhibitor K252a (n = 15, P < 0.05, 10 M). (2) In all electrophysiological recording, the patched cell was initially held at a -40 mV command potential. In group A, we captured inward current (46 ± -8 15 pA, P < 0.05, n = 9, 10 M BDNF) after treatment at 60 seconds, which could also be suppressed by K252a in group B. Conclusions: BDNF and its downstream signal pathway appear to 2+ regulate the activity and Ca release of intestinal smooth muscle. It could explain part of the pathogenesis of functional constipation. S34 ANMA 2015 India Selected Poster Presentation No. 35 No. 37 The Evaluation of Peroral Esophageal Myotomy for Achalasia Correlation Between High-resolution Manometry Metrics and Symptoms, Symptomatic Outcomes of Peroral Esophageal Myotomy in Achalasia Hu Yue, Lu Bin, Li Meng, and Chu Li First Affiliated Hospital of Zhejiang Chinese Medical University, Hangzhou, China Yu-Rong Tang, Mei-Feng Wang, Chen Xie, Liu-Qin Jiang, Rui-Hua Shi, and Lin Lin Department of Gastroenterology, the First Affiliated Hospital of Nanjing Medical University, Nanjing, China Background/Aims: To investigate the effect of peroral esophageal myotomy (POEM) on esophageal dynamics in patients with achalasia. Methods: From January 2012 to March 2014, a total of 35 patients with achalasia received POEM at Endoscopic Center in the First Affiliated Hospital of Zhejiang Chinese Medical University. Esophageal dynamics of all patients were evaluated by high-resolution manometry system preoperatively and one months after POEM the test was repeated. The characteristic of esophageal motility of the two tests were compared. Results: After POEM, lower esophagus sphincter resting pressure (LESP) decreased from 28.94 ± 18.70 to 16.02 ± 5.46 mmHg (P < 0.001) and descend rate was 44.6%. Four-second integrated relaxation pressure (4s-IRP) decreased from 27.18 ± 14.63 to 12.22 ± 6.75 mmHg (P < 0.001). Lower esophagus sphincter resting pressure (LESRR) decreased from 23.00 ± 18.55 to 12.22 ± 6.75% (P < 0.05). Intrabolus pressure decreased from 11.02 ± 5.36 to 4.90 ± 4.55 mmHg (P < 0.001). Distal contractile integral decreased from 2103.43 ± 1960.86 to 810.90 ± 1308.50 mmHg (P < 0.05). Esophageal body distal amplitude (average measurements at 3 cm and 7 cm above the lower esophageal sphincter) decreased from 26.21 ± 19.11 to 19.23 ± 9.74 mmHg (P < 0.05). The variation value of Eckhard score between pre- and post-POEM was correlation with the decline of 4s-IRP (r = 0.372, P = 0.036). After POEM, a small segment of proximal esophageal peristalsis appeared in two patients but was below normal level. Conclusions: POEM can improve esophagogastric junction relaxation and affect esophageal body contraction in patients with achalasia, but can not restore normal esophageal peristalsis. Bckground/Aims: Achalasia is an esophageal motility disorder characterized by failure of both esophagogastric junction relaxation and esophageal body peristalsis. High-resolution manometry (HRM) has improved the accuracy of manometry in detecting achalasia and defined clinically relevant subtypes. Peroral esophageal myotomy (POEM) is a novel endoscopic operation performed for the treatment of achalasia. This study investigated whether HRM metrics correlate with achalasia symptoms and symptomatic outcomes of POEM. Methods: Thirty patients with achalasia without previous surgery, and who underwent HRM were enrolled. Twenty-five patients were treated with POEM, and 12 patients repeat HRM 3 months after POEM. All of the patients enrolled at the beginning were asked to complete questionnaires that determined Eckardt scores at baseline, and symptoms of patients who treated with POEM were followed up about 6 months after surgery. Pearson correlation was used to assess the relationship of HRM metrics and Eckardt Scores at baseline, HRM metrics at baseline and symptomatic outcomes of POEM, HRM metrics changes, and Eckardt Score changes after POEM. Results: Thirteen type I, 16 type II, and 1 type III achalasia patients were enrolled. At baseline, Eckardt scores and HRM metrics (integrated relaxation pressure [IRP], lower esophageal sphincter [LES] relaxation rate, LES length) were similar between type I and type II achalasia except mean distal esophageal pressure in swallows (P = 0.000), and panesophageal pressurization rate in type II achalasia was raged from 20% to 100%. IRP was positively correlated with total Eckardt scores (P = 0.016), regurgitation (P = 0.048), and weight loss (P = 0.000) in all achalasia patients. And it was correlated with weight loss in type I achalasia (P = 0.000). No correlation was found between Eckardt scores and other HRM metrics. Twenty-five patients (10 patients with type I and 15 patients with type II achalasia) were treated with POEM, and their total Eckardt scores and scores of each symptom were decreased after surgery (vs before POEM, all P < 0.05). Eckardt scores changes (Eckardt scores before POEM minus Eckardt scores after POEM) were no difference between type I and type II achalasia. Eckardt scores and weight loss changes were positively correlated with IRP at baseline (all P < 0.05), and no correlation was found between other HRM metrics at baseline and S35 ANMA 2015 India Selected Poster Presentation Eckardt scores changes. Twelve patients (4 patients with type I and 8 patients with type II achalasia) underwent HRM after POME, IRP was changed significantly after POEM (vs before POEM, P = 0.005), and so were mean distal esophageal pressure changes in type II achalasia (vs before POEM, P = 0.010). IRP changes (IRP before POEM minus IRP after POEM) were positively correlated with Eckardt scores changes (P = 0.029). Conclusions: IRP correlates with symptoms and symptomatic outcomes of POEM in achalasia patients. HRM is an effective way to assess the severity of achalasia, and can be used to predict the efficacy of POEM. No. 38 Study on Effects of Electrical Stimulation on Rabbit Esophageal Body Motility In Vivo Lili Zhang, Wei Zhao, Chunshan Zhao, Hong Jin, Qi Yao, Guojian Zhou, Xiaoxuan Xu, and Bangmao Wang Department of Digestive Diseases, General Hospital, Tianjin Medical University, Tianjin, China Background/Aims: Abnormal esophageal motility was a prominent mechanism for achalasia. Though there have been many methods to relax lower esophageal sphincter (LES), the effective method to regain peristalsis of esophagus still lack. Experiments have confirmed that electric stimulation (ES) could induce contraction of smooth muscle. While, if ES could induce peristalsis of esophagus was uncertain. The aim of this study was to analyze the effects of ES on rabbit esophageal motility and the related mechanism in vivo. Methods: The study was performed on 12 rabbits. After anesthesia, esophagus was exposed and one pair of electrodes was implanted on esophageal subserosa in lower segment of esophagus, then the electrodes were connected to an electrical stimulator. The electrical stimulation signal was bipolar rectangular voltage trains, lasting for 3.0 seconds, with different current (1.0, 3.0, 5.0, and 10.0 mA), and frequency (10.0, 20.0, and 50.0 Hz). The amplitude and scope of esophageal contraction was recognized by the High-resolution manometry system. The effect of ES was tested under anesthesia and following intravenous administration of atropine (0.05 mg/kg), phentolamine (0.05 mg/kg), and L-NAME (50 mg/kg). Results: ES induced an esophageal contraction on the stimulated site. (1) From the current of 3.0 mA the contraction of esophagus could be recognized, the most high pressure increased was 48.5 ± 1.3 mmHg with the frequency 50.0 Hz; with current 5.0 mA and frequency 50.0 Hz, the most high pressure increased was 49.1 ± 2.5 mmHg; with current 10.0 mA and frequency 50.0 Hz, the most high pressure increased was 50.7 ± 2.4 mmHg, the difference was significant (P = 0.002). (2) The latency period between ES and contraction of esophagus was 50.0 ± 10.0 msec. The length of latency period was not influenced by stimulation parameters. (3) The esophageal contraction caused by electrical stimulation was restricted to the stimulated point (the scope was 2.0 ± 0.2 cm, not influenced by stimulation parameters). (4) During ES, atropine, phentolamine, and L-NAME had no effect on the amplitude of esophageal contraction induced by ES. Conclusions: ES could induce esophageal contraction on the stimulated site in vivo, following a quite short latency period, and this effect was not mediated by neurotransmitters. The amplitude of esophageal contraction was current and frequency dependent. S36 ANMA 2015 India Selected Poster Presentation No. 40 No. 43 Effectiveness of N-acetylcysteine on the Treatment of Achalasia Symptomatic and Manometric Spectrum of Esophageal Motility Disorders in a Tertiary Care Institute in Northern India Wei Zhao, Lili Zhang, Hong Jin, Lanlan Wu, and Bangmao Wang Department of Digestive Diseases, General Hospital, Tianjin Medical University, Tianjin, China Background/Aims: Achalasia still lack effective treatments. Especially, traditional medication was considered to be unsatisfactory. Was there other medication which could help to cure achalasia? This paper was to report a clinical finding, that N-acetylcysteine (NAC) might be able to relieve symptoms of achalasia and reduce lower esophageal sphincter pressure (LESP). Methods: Eight patients with Achalasia (M:F = 5:3, age 43.2 ± 10.5 years) who take NAC (Flumucil effervescent tablet, 200 mg tid)for the treatment of cough with phlegm were under observation. The NAC treatment lasted for 2 weeks. The observation lasted for 4 weeks including NAC treatment period and the following 2 weeks. During the observation, any other medication, especially traditional medication for achalasia, such as nifedipine and isosorbide mononitrate, was abandoned, and all the patients were asked to keep their previous diet and life style. The symptoms of achalasia were evaluated by Eckardt score before treatment, at the end of the second week and at the end of the fourth week. At the same time, high-resolustion esophageal monometry were also taken, and the relaxation function of lower esophageal sphincter (LES) was evaluated by 4-second integrated relaxation pressure (4s-IRP). Results: At the end of NAC treatment, all patients reported an obvious relief of achalsia symptoms (Eckardt score: 10.2 ± 3.5 vs 6.4 ± 2.6, P = 0.001), and, interestingly, LESP were also reduced significantly (4s-IRP: 20.4 ± 6.2 mmHg vs10.4 ± 4.3 mmHg, P = 0.001). During the period, no side effects were observed. But, at the end of the fourth week, there was a relapse both in achalasia symptoms (Eckardt score: 9.2 ± 4.1 vs 6.4 ± 2.6, P = 0.001) and in LESP (4s-IRP: 16.7 ± 4.4 mmHg vs 10.4 ± 4.3 mmHg, P = 0.001) compared with that at the end of second week. Conclusions: NAC might relieve symptoms of achalasia. This effect might be relevant with the reduced LESP. But the mechanism was still not clear. Omesh Goyal, Monika Bansal, Ajit Sood, Varun Mehta, Sandeep S Sidhu, and Rajoo S Chhina Department of Gastroenterology, DMC and Hospital, Ludhiana, India Background/Aims: Data on the spectrum of esophageal motility disorders in Indian population is scarce. We aimed to study the symptomatic and manometric profile of patients with suspected esophageal motility disorders. Methods: Consecutive patients with esophageal symptoms and normal esophago-gastro-duodenoscopy referred for esophageal manometry from 2010 to 2014 were included. High-resolution esophageal manometry was performed with 22-channel water-perfusion system (MMS). Chicago classification was used to classify motility disorders. Results: Of the 304 patients studied (mean age 43.6 years, 61% males), 161 presented with dysphagia, 122 with retro-sternal discomfort/pain and 22 with regurgitation. Out of the patients with dysphagia, 35.4% had weak peristalsis with large/small breaks, 27.3% had achalasia cardia (AC), 8.7% had rapid contractions with normal latency, 6.2% had frequent failed peristalsis, 4.3% had diffuse esophageal spasm (DES), 0.6% had nut-cracker esophagus while 12.8% had normal manometry. Of the patients with retro-sternal discomfort, 40.2% had weak peristalsis with large/small breaks, 8.2% had rapid contractions with normal latency, 6.6% had AC, 4.1% had frequent failed peristalsis while 39.3% had normal manometry. Duration of dysphagia at presentation was longer in AC patients than those with weak peristalsis (34.8 ± 33.5 months vs 16.4 ± 18.3 months, P = 0.052). Associated regurgitation and bolus obstruction were more frequent in patients with AC than those with weak peristalsis. Conclusions: Dysphagia was the commonest esophageal symptom followed by retro-sternal discomfort/pain at our centre. Among dysphagia patients, weak peristalsis was the commonest high-resolution manometry finding followed by AC. Weak peristalsis was also the commonest finding among patients with retro-sternal discomfort/pain, followed by rapid contractions.

Methods: All persons undergoing FEES were prospectively evaluated. A flexible fiberoptic endoscope (XP260 gastroscope) was passed transnasally (without topical anesthesia or nasal constriction) into the more patent nostril. Nasopharyngeal and laryngeal anatomy was first evaluated. Laryngopharyngeal sensory and motor function was then assessed, followed by a comprehensive swallowing evaluation. Six parameters were prospectively evaluated. These included the failure of FEES, airway compromise, epistaxis, change in heart rate, level of discomfort, and vasovagal syncope. Descriptive statistics were calculated. Results: A total 303 examinations were performed during the study period. The failures of FEES occurred in 5 patients (0.2%) due to high risk of aspiration or poor cooperation. After exclusion of failed examinations, mild epistaxis occurred in 22 examinations (7.3%) and there was no case of vasovagal syncope. There was one episode (0.3%) of decreased oxygen saturation below 90%, the patient recovered soon by supportive therapy with oxygen supply. There was no statistically significant difference between the average pretest and post-test heart rates; no patients became symptomatically bradycardic or tachycardic. The discomfort ratings were as follows; 128 examinations (43.0%) rated the overall discomfort of the test as none, 150 examinations (50.3%) as mild, 18 examinations (6.0%) as moderate, and 2 (0.7%) examinations were described as severe discomfort. Conclusions: Flexible endoscopic evaluation of swallowing is a safe, well-tolerated procedure to objectively evaluate patients with dysphagia when performed by an experienced gastrointestinal endoscopist. S38 Background/Aims: Esophageal pressure topography (EPT) based Chicago classification is the standard for characterization of esophageal motility disorders (EMD) in adults. There is limited data regarding its applicability in children. We evaluated the spectrum of EMD by EPT based diagnosis in children. Methods: Forty-seven children (27 boys, median age 14 [6-18] years) underwent esophageal high-resolution manometry (MMS) with a 22 channel Dent sleeve water perfusion catheter. EPT metrics were derived for 10 liquid swallows and Chicago classification was applied. Results: Of the 47 children, 32 (68%) had a normal study and 15 (32%) had a motility disorder (achalasia-11, hypotensive lower esophageal sphincter [LES]-2, frequent failed peristalsis-1, and weak peristalsis with large peristaltic defects-1). Type I achalasia was present in 6 (55%) and type II in 5 (45%) cases. Pan-esophageal pressurization (> 30 mmHg) was present in 50 % (30-100) swallows in type II achalasia. The basal LES and 4-second integrated relaxation pressure was 20 (11-60) and 31 (15.2-55) mmHg respectively. Dysphagia (11 [100%]) was the most common symptom followed by regurgitation (9 [82%]), weight loss (7 [64%]), and chest pain (3 [27%]). Barium swallow and esophagogastroscopy were also suggestive of achalasia in these cases. Two patients with peristaltic dysfunction had extrahepatic portal vein obstruction (EHPVO) with persistent dysphagia despite adequate dilatation of the post-sclerotherapy stricture. Both patients with hypotensive LES had reflux disease and presented with vomiting. Conclusions: EPT is a useful technique to diagnose EMD in children. Achalasia is the most common disorder, with type I and II being equally frequent ANMA 2015 India Selected Poster Presentation No. 47 No. 48 Surgery for Achalasia Cardia: One Time Treatment Modality in Develping Countries Multichannel Intraluminal Impedance-pH Monitoring Confirms Less Than 2.5 Hours Dinner-bedtime Interval, Obesity Were Associated With Nocturnal Gastroesophageal Reflux Other Than Age and Gender Abhijit Chandra, Vishal Gupta, Saket Kumar, Ajeet P Maurya, Hunaid Hatimi, and Rahul Department of Surgical Gastroenterology, King George's Medical University, Lucknow, India Nian Yuanyuan, Wang Xueqin, Wu Jing, Cheng Yan, and Zhang Jun Division of Gastroenterology, The Second Affiliated Hospital of Xi'an Jiaotong University, Xi'an, China Background/Aims: Two main treatment modalities for achalasia cardia are laparoscopic Heller's myotomy (LHM) and endoscopic balloon dilation. Here we present our experience of LHM as the first line one time treatment for achalasia. Methods: Hospital data from January 2009 to December 2013 was analyzed. Preoperative assessment included esophagogastroduodenoscopy, barium swallow and manometry. Results: Thirty-five patients (male 19, median age 31 years, range 12-65) underwent LHM. All patients had dysphagia (median duration 48 months [range 1-240]) and 8 (22.8%) had chest pain. Four (11%) patients had recurrent achalasia. Most of the patients (80%) came from rural areas and 68.5% were ≤ 40 years of age. Fundoplication (mostly Toupet's) was added in all except 4 patients (1 megaesophagus, 1 left lobe hepatomegaly, 2 post-surgical recurrent achalasia). Median operative time was 180 minutes (range 120-300) with one conversion (due to mucosal injury). Intraoperative complication included mucosal injury (n = 2) and pleural breach (n = 3). Median postoperative stay was 7 days (range 4-27) with a morbidity of 5.7% (leak 1, subphrenic collection 1). One patient died postoperatively due to myocardial infarction. With a median follow-up of 9.5 months (range 1-47 months), 4 (11.4%) patients had recurrent dysphagia, and 3 (8.5%) had gastroesophageal reflux. Most of the patients (6/8) had relief in chest pain. Conclusions: Predominance of rural patients, young (< 40 years) patients, and males in this study suggest LHM may be the first line treatment for achalasia in developing countries like India where predominant population is rural that prefer one time treatment. Background/Aims: To assess nocturnal reflux parameters by multichannel intraluminal impedance-pH (MII-pH) monitoring in gastroesophageal reflux disease (GERD) patients with nocturnal gastroesophageal reflux (nGER), in order to find the influences of gender, age, body mass index (BMI), and dinner-bedtime interval on the nGER. Methods: One hundred and thirty suspected GERD patients with typical symptoms underwent 24-hour MII-pH monitoring. When patients had pathological gastroesophageal reflux, we cut out the impedance and pH information of evening duration (from the end of of last evening meal, to the start of breakfast). Ninety-seven patients (46 males, average ages 51.27 ± 12.15 years) with nGER were included, and they were subgrouped according the gender, age, BMI, and dinner-bedtime interval respectively. Data between groups were analyzed using SPSS17.0 software. Results: One hundred and thirty suspected GERD patients had accepted 24-hour MII-pH monitoring, 74.62% (97/130) of them had nGER, 18.56% (18/97) patients had reflux symptoms. Ninety-seven patients were subgrouped on the basis of different dinner-bedtime interval (2, 3, and 4 hours) respectively, reflux parameters quantifying nGEJ such as %time < 4, numbers of reflux episodes, and numbers of long reflux episodes, had no difference between groups. Then patients were subdivided as patients with dinner-bedtime interval < 2.5 hours and patients with dinner-bedtime interval ≥ 2.5 hours, it is found that patients with time interval less than 2.5 hours had higher figures in %time < 4 and duration of the longest reflux episode, had more acid refluxes, weakly acidic refluxes, liquid refluxes, mixed refluxes, gas refluxes, and lower nadir pH. All of them had significant differences. Obese (BMI ≥ 25) GERD patients had higher %time pH < 4, numbers of reflux episodes and duration of the longest reflux episode in nocturnal period than GERD patients with normal BMI. There were no differences between GERD patients with low BMI, normal BMI, and over-weight. Although nocturnal volume clearance time were longer in female GERD patients than male, and also were longer in elder GERD patients than younger, but other reflux parameters were no statistically different between groups. Conclusions: Less than 2.5 hours dinner-bedtime interval, obesity (BMI ≥ 25) were associated with nGER, gender and age had no influences on the nGER, but female patients and elder patients had lower esophageal clearance. This study comprehensively analyzed the influences of dinner-bedtime interval, firstly and objectively indicated dinner-bedtime interval ≥ 2.5 hours could reduce nocturnal reflux. S39 ANMA 2015 India Selected Poster Presentation No. 50 No. 51 Efficacy and Safety of Pneumatic Dilatation for Achalasia Esophageal Motility in Patients With Corrosive Esophageal Stricture Cheol Woong Choi, Hyung Wook Kim, Dae Hwan Kang, Su Bum Park, Su Jin Kim, Hyeong Seok Nam, Dong Ku Kang, and Ja Jun Goo S K Sinha, B Nagi, N Berry, PK Sidappa, K Singh, and R Kochhar Department of Internal Medicine, Pusan National University Yangsan Hospital, Yangsan, Gyeongsangnamdo, Korea Department of Gastroenterology, Post Graduate Institute of Medical Education and Research, Chandigarh, India Background/Aims: To study the esophageal motility in patients with chronic corrosive stricture. Methods: This prospective study included patients with chronic corrosive stricture of esophagus who were on stricture dilatation programme. Patients were included at least 6 months after intake of corrosive substance. Patients who were not willing to participate in study were excluded. Clinical details of each patient were recorded. Each patient underwent esophageal manometry by station pull through technique. Manometric studies were performed on a water perfused system from MMS. Results: The study included 18 patients (14 males, 77.8%) with mean age of 34.9 ± 11.5 years. Sites of esophageal stricture were as follows: upper third in 3 patients, middle third in 9 patients, lower third in 4 patients, and at multiple level in 2 patients. Resting lower esophageal sphincter (LES) pressure was low in 4 patients, three of them had stricture in middle third and one had multiple strictures. LES relaxation was normal all patients. Peristaltic waves were present in all patients. In patients with upper third stricture, the wave form in upper third showed normal pattern in 1 and bizarre pattern in 2 patients. In the middle third of esophagus, wave form was normal in 1, bizarre in 1 and of low amplitude in 1 patient. Same pattern of wave form was seen in lower third of esophagus. In patients with middle third stricture, the wave form in upper third showed normal pattern in 4 and bizarre pattern in 1 and reduced amplitude in 4 patients. The wave form in middle third showed normal pattern in 2 and bizarre pattern in 3 and reduced amplitude in 4 patients. The wave form in lower third showed normal pattern in 4 and bizarre pattern in 1 and reduced amplitude in 4 patients. In patients with lower third stricture, motility in upper and middle third was normal in all patients. The wave form in lower third showed normal pattern in 1, bizarre pattern in 2 and reduced amplitude in 1 patient. Out of 2 patients with multiple level strictures, one had bizarre wave form in whole esophagus; the other patient had reduced wave amplitude in whole esophagus. Conclusions: Most patients with corrosive stricture of esophagus have altered esophageal motility. Such motility disturbances are not restricted to stricture segment only. Backgraund/Aims: Pneumatic balloon dilation is a most safe and effective nonsurgical treatment to relieve functional obstruction of the gastroesophageal junction in achalasia. In this retrospective study, we reported a 4-years’ experience with pneumatic dilation treatment in patients with primary achalasia, and determined whether previously described predictors of outcome remain significant after endoscopic dilation. Our aim was to determine the safety and the short and long-term efficacy of pneumatic dilatation. Methods: Between August 2009 to October 2013, 16 patients consecutive patients with primary symptomatic achalasia (diagnosed by endoscopy, clinical presentation, barium esophagogram, and manometry) who received pneumatic balloon dilation. It was reviewed retrospectively on single center experience. Six males and ten females were included and their average age was 47.7 ± 21.9. Mean age at time of diagnosis years was 43.2 ± 21.9. Remission was assessed by a structured interview and a previous symptoms score. Results: Symptoms were dysphagia (n = 16, 100%), regurgitation (n = 13, 81.3%), chest pain (n = 3, 18.0%), and weight loss (n = 2, 12.5%). The median number of dilatations was 1.9 ± 1.6. A total of 31 dilations were performed in 16 patients; 8 patients (50%) underwent a single dilation, 5 patients (31.3%) required a second procedure, and 2 patients (12.5%) underwent over third procedure. Five patients were required a second pocedure within a median of 16.7 months (range 4-36 months), and 2 patients (12.5 %) underwent a third procedure within a median of 36 months. The mean duration of symptoms prior to treatment was 15.0 ± 13 months. Symptom score at baseline,1 and 12 months after dilation. Post dilatation major complication (perforation and bleeding) was none. Conclusions: Pneumatic dilatation is an effective procedure in the treatment of primary achalasia during the short- and long-term period. Treatment evaluation can possibly be made objectively with radiographic and manometric alterations of esophagus that occurred after pneumatic dilatation. S40 ANMA 2015 India Selected Poster Presentation No. 52 No. 53 Classic and Vigorous Achalasia: Change From One Form to Another Etiological Spectrum of Motor Dysphagia as per Chicago Classification: Experience at a Tertiary Center in Central India 1 1 2 1 1 1 S K Sinha, B Nagi, A Lal, S S Rana, D K Bhasin, R Kochhar, J 1 1 Samanta, and K Singh Mayank Jain, Sandip Ware, Amit Bundiwal, Shohini Sircar, and Ajay K Jain Departments of 1Gastroenterology and 2Radiodiagnosis, Post Graduate Institute of Medical Education and Research, Chandigarh, India Department of Gastroenterology Choithram Hospital and Research Center, Indore, India Background/Aims: To study changes in esophageal motility pattern in patients with achalasia cardia during follow-up. Methods: This prospective study included consecutive patients with achalasia cardia. Achalasia cardia was diagnosed on the basis of history of dysphagia, typical appearance on barium swallow and esophageal manometry findings of incomplete relaxation of lower esophageal sphincter (LES) and absence of peristalsis in esophageal body. Patients unwilling to participate were excluded. Patients were treated with pneumatic balloon dilatation using Rigiflex balloon or surgical cardiomyotomy. Balloon dilatation was repeated after 4-8 weeks if there was residual dysphagia. Esophageal manometry was repeated within a month of dilatation or surgery and then once in 3-6 months. Manometric criteria for the diagnosis of classic achalasia was incomplete relaxation of LES (residual pressure > 8 mmHg) and absence of peristalsis in esophageal body with contraction amplitudes < 40 mmHg. When esophageal contractions had amplitude > 40 mmHg, it was classified as vigorous achalasia. Results: The study included 67 patients (38 males, 56.7%) with mean age of 37.9 ± 14.8 years. Mean duration of follow up was 12.9 ± 21.6 months. Fourteen patients (20.9%) got lost to follow-up after single manometry examination. Out of remaining 53 patients, 44 (83%) patients (24 males) had classic achalasia cardia on initial manometric study and 9 (17%) patients (7 males) had vigorous achalasia. Demographic profile of patients with classic achalasia did not differ significantly from those with vigorous achalasia. Out of 44 patients with classic achalasia, 2 patients (4.5%) showed change in pattern of esophageal motility to vigorous achalasia. Out of 9 patients with vigorous achalasia cardia, 3 (33.3%) showed change in motility pattern to classic achalasia. Conclusions: Classic and vigorous achalasia cardia are not exclusive groups and change from one form to another occurs in a subset of patients. Background/Aims: The aim of the present study was to analyse the demographic, symptomatic and manometric profile of patients with motor dysphagia at a tertiary referral center in Central India using the recent Chicago classification. Methods: This is a retrospective analysis of data. The records of all patients who underwent high-resolution esophageal manometry for suspected motor dysphagia from March 2012 to March 2014 were analysed. Motor dysphagia was defined as dysphagia for solids and/or liquids of more than one month duration with normal endoscopic examination. The manometry study was done in right lateral position using 16 channel water perfusion systems (Ready Stock, Australia). Reporting was done by a single observer. The data was analysed for age, sex, symptoms, and manometric findings. Results: A total of 70 patients formed the study group. The mean age was 43.1 years and thirty nine were males. The major symptoms reported were dysphagia for solids (90%), dysphagia for liquids (75.7%), regurgitation (47.1%), chest pain (31.4%), weight loss (31.4%), and respiratory complaints (5%). The etiological causes for motor dysphagia, based on High-resolution manometry findings, were as follows: achalsia cardia (40), distal esophageal spasm (6), hypertensive peristalsis (5), scleroderma esophagus (5), non specific dysmotility (5), hypotensive LES (4), frequently failed peristalsis (1), weak peristalsis with small (1) and large defects (2), and cricopharangeal achalasia (1).Type I achalsia was the commonest form (21/40) followed by type II (15/40), and type III (4/40) variants. Conclusions: Majority of patients with motor dysphagia present with dysphagia for solids and liquids. Regurgitation, chest pain, and weight loss are seen in one third of the patients. Achalsia cardia is the commonest cause of motor dysphagia. Type 1 achalsia was the most common variant of achalsia in our study. S41 ANMA 2015 India Selected Poster Presentation No. 54 No. 55 Esophageal Motility Abnormalities and the Influence on Esophageal Acid Exposure in Patients With Gastroesophageal Reflux Disease Utility of Esophageal Manometry in Diagnosing Pediatric Gastrointestinal Motility Disorders Maneesh Paliwal, Sakshi Karkra, Rajesh Puri, Neelam Mohan, and Randhir Sud Yuantao Hou, Xiaohong Sun, Xiaoqing Li, Zhifeng Wang, Liming Zhu, Huijun Shu, Guijun Fei, Meiyun Ke, and Xiucai Fang Department of Pediatric Gastroenterology, Hepatology and Liver Transplantation, Medanta Institute of Digestive and Hepatobiliary Sciences, Gurgaon, Haryana, India Department of Gastroenterology, Peking Union Medical College Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College, Beijing, China Background/Aims: Esophageal manometry has evolved from a research tool to a diagnostic modality with wide availability. It is an excellent tool to define the integrity of peristalsis and esophagogastric junction function. The utility of esophageal manometry in clinical practice is to accurately define normal and abnormal esophageal motor function and accordingly to delineate a treatment plan based on motor abnormalities. Objective of this study was to determine the usefulness of esophageal manometry in establishing a diagnosis in children with recurrent vomiting, dysphagia, and chest pain. Methods: We analyzed our data of pediatric population defined as less than 18 years of age from march 2013 till September 2014. Esophageal manometry was done using 22 channel water perfusion high-resolution esophageal manometry catheter (Solar HRM). The procedure was done without sedation on all the patients. The results were analyzed using computer software based on Chicago classification. Results: HRM was done on 19 subjects (15 males) with a mean age of 14.1 years. Underlying diseases were as follows; 10 had recurrent vomiting, 8 dysphagia and one chest pain. In 3 of the 4 (79%) patients who had clinical history of Rumination syndrome on the basis of Rome III criteria , the postprandial manometry showed an esophageal pressure pattern compatible with rumination. All had an amplitude > 30 mmHg from baseline in abdomen and esophagus. Three out of remaining seven in the same group had low baseline lower esophageal sphincter pressure and were evaluated further for gastroesophageal reflux disease (Subsequently proven on 24 hour esophageal impedance-pH analysis) while rest were normal. Five of the eight (62.5%) patients in dysphagia group had type II achalasia with mean lower esophageal sphincter pressure of 43 mmHg, with mean Integrated relaxation pressure of 20 mmHg and no peristaltic activity. One patient with dysphagia had distal esophageal spasm, while other 2 patients had normal manometry pattern. Patient with chest pain had normal study. Conclusions: Esophageal manometry is a useful modality in pediatric subjects with persistent vomiting and dysphagia. Rumination syndrome and achalasia in childhood can be accurately diagnosed using Chicago classification. Background/Aims: To study the characteristics of esophageal motility abnormalities in patients with gastroesophageal reflux disease (GERD) and their influences on esophageal acid exposure. Methods: We enrolled 15 reflux esophagitis (RE) patients and 12 non-erosive reflux disease (NERD) patients with typical reflux symptoms, and 10 healthy subjects (HS) as controls. All subjects underwent esophageal manometry and esophageal 26 hours pH monitoring, and 3 kinds of standardized meals are applied during the pH monitoring. Results: The abnormalities of esophageal motility in GERD patients are mainly presented as decreases of lower esophageal sphincter pressure (LESP) and distal esophageal body pressure compared with HS. We divided GERD patients into 3 groups according to their esophageal motility abnormalities: (1) LESP decrease group (n = 16), (2) ineffective esophageal motivation (IEM) + LESP decrease group (n = 7), (3) IEM group (n = 3), one NERD patient has normal esophageal motility. In RE and NERD patients, the proportion of 3 subtypes of esophageal motility abnormalities' has significant difference (P = 0.017). All patients in IEM + LESP decrease group are with RE, their total number of acid exposure ([144.14 ± 153.64] vs [51.06 ± 36.14], P = 0.023) and the total acid exposure time ([14.54 ± 13.25%] vs [5.13 ± 4.78%], P = 0.017], the acid exposure time in fasting ([2.93 ± 2.46%] vs [0.65 ± 1.16%], P = 0.014) are higher than LESP decrease group. Conclusions: Esophageal motility abnormalities in GERD patients are characterized by LESP and IEM in distal esophagus. Decrease of LESP and IEM were associated with enhanced esophageal acid exposure, which might explain the occurrence of esophageal mucosa damage in RE patients. S42 ANMA 2015 India Selected Poster Presentation No. 57 No. 58 Corticotropin-releasing Factor Changes the Phenotype and Function of Mouse Mesenteric Lymph Nodes Dendritic Cells Characteristics of Mouse Mesenteric Lymph Nodes Dendritic Cells and Their Ability to Secrete Corticotropin Releasing Factor Wang Xiaoteng, Lu Bin, Li Meng, and Hu Yue Wang Xiaoteng, Lu Bin, Li Meng, and Hu Yue First Affiliated Hospital of Zhejiang Chinese Medical University, Hangzhou, China First Affiliated Hospital of Zhejiang Chinese Medical University, Hangzhou, China Background/Aims: Dendritic cells (DCs) significantly contribute to the pathology of several chronic inflammatory autoimmune disorders. However, little is known of the contribution of corticotropin-releasing factor (CRF) to intestinal DCs. In this study, we try to investigate the role of CRF in the change of intestinal dendritic cell phenotype and function. Methods: The mice mesenteric lymph nodes dendritic cells (MLNDCs) were obtained by the technique of magnetic bead sorting. Expression of CRF receptor 1 (CRF1)/CRF2 on the surface of MLNDCs were determined by double-labeling immunofluorescence and polymerase chain reaction. Then, MLNDCs were exposed to CRF with or without the presence of CRF1 and CRF2 receptor antagonists, the expression of surface molecules (MHC I and MHC II) and co-stimulatory molecules (CD80 and CD86) were tested by the technique of flow cytometry and Western blot, the capacity to stimulate T cells was evaluated by mixed lymphocyte reaction (MLR). Results: Both the CRF receptors (CRF1 and CRF2) exist on the surface of MLNDCs. CRF could increase the expression of CD86 and MHC II of MLNDCs as well as the capacity to stimulate T cells. MLNDCs treated with CRF1 receptor antagonist had less-activated phenotype characterized with lowered surface expression of MHC II, CD86, and consequently had reduced capacity to stimulate T cells, while MLNDCs treated with CRF2 receptor antagonist showed an opposite result. Conclusions: Our findings suggest that CRF could change the phenotype and function of mouse intestinal DCs by acting on CRF1 and CRF2 receptors directly. The pathway of CRF1 and CRF2 receptors show opposite effects. Background/Aims: To study the phenotype and function of mouse mesenteric lymph nodes dendritic cells (MLNDCs) and their ability to secrete corticotrophin releasing factor (CRF) Methods: The mice mesenteric lymph nodes dendritic cells were obtained by the technique of magnetic bead sorting and cultured with or without lipopolysaccharide (LPS). Then the expression of surface molecules (MHC I and MHC II) and co-stimulatory molecules (CD80 and CD86) were analyzed by flow cytometry. The capacity to stimulate T cells was evaluated by mixed lymphocyte reaction (MLR). The enterogenous production of CRF in MLNDCs was determined by PCR and western blot, the expression of CRF receptor 1 (CRF1)/CRF2 on the surface of MLNDCs were determined by double-labeling immunofluorescence. Results: Fresh isolated MLNDCs express high level of MHC II and had the ability to attract and stimulate CD4+/CD8+ T cell proliferation. LPS could not change the phenotype and function of MLNDCs. MLNDCs had high level of CRF mRNA transcription and protein expression. Immunofluorescence assay showed that both the CRF receptors (CRF1 and CRF2) exist on the surface of MLNDCs. Conclusions: Mouse MLNDCs are in a mature state and can produce high level of CRF. And this finding indicate that MLNDCs maybe an important source of peripheral CRF.

We evaluated selected fecal microbes in IBS patients and healthy controls (HC). Methods: Fecal 16S rRNA copy number of selected bacteria was studied using qPCR in 47 patients with IBS (Rome III) and 30 HC. Results: Of 47 patients, 20 had constipation-predominant IBS (IBS-C), 20 diarrhea-predominant IBS (IBS-D), and 7 un-classified IBS (IBS-U). Relative difference in 16S rRNA copy number of Bifidobacterium (P = 0.040) was lower while Ruminococcus productus-Clostridium coccoides (P = 0.020), Veillonella (P < 0.01), Bacteroides thetaiotamicron (P < 0.001), Pseudomonas aeruginosa (P < 0.001), and gram-negative bacteria (P < 0.01) higher among IBS patients than HC. Number of Lactobacillus (P < 0.01) was lower while Bacteroides thetaiotamicron (P < 0.001) and segmented filamentous bacteria (SFB, P = 0.010) was higher among IBS-D than IBS-C. Numbers of Bacteroides thetaiotamicron (P < 0.001), Pseudomonas aeruginosa (P < 0.001), and gram-negative bacteria (P < 0.01) were higher among IBS-C and IBS-D than HC. Quantity of SFB was higher among IBS-D (P < 0.001) and lower among IBS-C (P < 0.01) than HC. Number of Veillonella species was higher among IBS-C than HC (P < 0.01). Pseudomonas aeruginosa was frequently detected among IBS than HC (46/47 [97.9%] vs 10/30 [33.3%], P < 0.001). Higher number of Bacteroides thetaiotamicron, Clostridium coccoides, Pseudomonas aeruginosa, gram-negative and SFB was associated with visible abdominal distension and Clostridium coccoides and gram-negative bacteria with bloating. Microbial flora was different among IBS than HC on principal component analysis. Conclusions: Fecal microbiota was different among IBS than HC and different sub-types were associated with different microbiota. Pseudomonas aeruginosa was more frequent and higher in number among IBS patients. Department of Gastroenterology, Sanjay Gandhi Postgraduate Institute of Medical Sciences, Lucknow, India Background/Aims: Circulating levels of pepsinogen (PG), gastrin-17 (G-17) are known serological marker of gastric acid secretion; Helicobacter pylori infection is known to alter acid secretion, which may be influenced by pro-inflammatory cytokines (eg, IL-8) through degree and severity of gastritis. Since altered acid secretion may be associated with functional dyspepsia (FD), we undertook this study. Methods: Serum levels of PG-I, PG-II, PG-I/PG-II ratio, G-17, IL-8, and anti-H. pylori IgG were estimated (ELISA) among 60 subjects with FD (Rome III criteria and normal endoscopy) and healthy controls (HC). Results: Age (mean ± SD: 48.2 ± 10.4 vs 51.7 ± 12.1), gender (male: 41 [68.3%] vs 40 [66.7%]) and H. pylori sero-positivity (44 [73.3%] vs 37 [61.7%]) were comparable among patients with FD and HC. Serum PG-I (median [range]: 76.1[5.3-199.2] vs 106.4 [29.4-225.0], P = 0.040) and PG-I/PG-II (5.6 [0.5-66.4] vs 9.8 [1.8-28.8], P = 0.005) were lower but serum G-17 (12.1 [0.2-42.9] vs 7.3 [0.6-73.3], P = 0.045), and IL-8 (55.1 [4.2-318.9] vs 26.3 [4.7-277.6], P = 0.02) were higher among FD than HC, though PG-II was comparable. FD patients without H. pylori infection also had lower serum PG-I (72.9 [26.1-192.4] vs 113.8 [29.4-225.0], P = 0.003), PG-I/PG-II (5.4 [1.0-66.3] vs 8.4 [3.6-28.8], P = 0.001), and higher G-17 (17.1 [1.9-42.9] vs 5.0 [0.9-73.3], P = 0.048), and IL-8 (29.5 [8.1-163.9] vs 18.9 [4.7-101.9], P = 0.030) levels than HC, though the serum levels were comparable among H. pylori sero-positive subjects with FD and HC. Conclusions: Circulating levels of PG-1 and PG-I/PG-II were lower but G-17 and IL-8 were higher among patient with FD than HC, particularly those without H. pylori infection, suggesting that acid secretion may be higher among patients with FD without H. pylori infection than HC. S44 ANMA 2015 India Selected Poster Presentation No. 61 No. 67 Metronidazole-resistant Helicobacter pylori Is More Prevalent in Patients With Dyspepsia Constipation in India Differs From West by Both Stool Frequency and Form 1 2 3 Juntaro Matsuzaki, Hideki Mori, Hitoshi Tsugawa, Tatsuhiro 2 2 2 2 Masaoka, Sawako Miyoshi, Seiichiro Fukuhara, Takanori Kanai, and Hidekazu Suzuki2 Gautam Ray and P. Manju Bhargav B R Singh Hospital, Kolkata, West Bengal, India 1 Center for Preventive Medicine, Keio University Hospital, Tokyo, Japan; Division of Gastroenterology and Hepatology, Department of Internal Medicine, Keio University School of Medicine, Tokyo, Japan; and 3 Department of Biochemistry and Integrative Medical Biology, Keio University, Tokyo, Japan 2 Background/Aims: Helicobactor pylori infection is thought to be one of the causes of dyspepsia symptoms. The aim of this study is to determine the characteristics of H. pylori strains associated with the presence of dyspepsia. Methods: Patients who have failed H. pylori eradication treatment with metronidazole-contained triple regimen were enrolled. H. pylori was isolated from these gastric biopsy specimens, and the minimum inhibitory concentrations (MICs) of metronidazole, clarithromycin and amoxicillin were evaluated. The mutations of reactive oxygen species (ROS)-scavenging enzymes, such as AhpC and NapA, in H. pylori were also investigated. The presence of dyspepsia symptoms is diagnosed based on the definition of functional dyspepsia in the Rome III criteria. Results: Twenty-eight patients with dyspepsia and 81 patients without dyspepsia were enrolled. Metronidazole-resistant H. pylori (MIC ≥ 8 g/mL) was more prevalent in patients with dyspepsia (89% in dyspepsia, 72% in non-dyspepsia, P = 0.060). The MIC levels of metronidazole were higher in patients with both postprandial distress symptoms (PDS) and epigastric pain symptoms (EPS) than patients with EPS alone among dyspepsia patients (35.5 g/mL vs 20.0 g/mL, P = 0.050). Among H. pylori strains isolated from patients with both PDS and EPS, the combination of AhpC mutations (A126S and I140V) and NapA mutation (I73L) was commonly observed. Conclusions: Metronidazole-resistance of H. pylori was associated with the presence of dyspepsia. H. pylori eradication therapy might be more effective for patients with dyspepsia in Asia than in Europe, since metronidazole-resistant H. pylori is more prevalent in Asia. The mutations of AhpC and NapA would be useful markers for the risk of dyspepsia. S45 Background/Aims: There is paucity of data regarding stool frequency and form in Indian patients complaining of constipation which are needed for its definition. Methods: In a prospective study 186 consecutive patients consulting doctor for their complaint of constipation completed a questionnaire containing Rome III criteria points of functional constipation and constipation predominant irritable bowel syndrome. Organic bowel diseases were excluded by further history taking, physical examination and appropriate investigations. Patients were asked to report their predominant stool form according to the Bristol stool chart. The data was then compared with the existing Indian population data. Results: Stool type 1-3 according to Bristol stool form scale was the predominant type present in 92.1% and conformed to Asian criteria of constipation. Twenty-eight percent had normal stool frequency by Indian standard (ie, at least 1 motion/day) and most others (51.5%) reported a frequency of 3-4/week. Subjective feeling was at variance with observed rate and only 35.4% had constipation by Western criteria (less than 3 motions/week). Feeling of incomplete evacuation was universal. Most patients of functional constipation were elderly with comorbidities. Only 3.2% had colonic cancer. Conclusions: Asian criteria for constipation based on stool form holds in Indian patients but frequency needs to be defined (< 5/week) and the subjective feeling of incomplete evacuation should be given due weightage in any definition of constipation in Indian context. ANMA 2015 India Selected Poster Presentation No. 68 No. 69 Impact of Memory Function in Patients With Irritable Bowel Syndrome Laparoscopic Ventral Mesh Rectopexy for Complete Rectal Prolapse: Intermediate-term Results From a Tertiary Care Institute Pei-Yi Liu and Ching-Liang Lu National Yang-Ming University, Taipei, Taiwan Abhijit Chandra, Vishal Gupta, Vivek Gupta, Saket Kumar, Rahul, and Hunaid Hatimi Department of Surgical Gastroenterology, King George's Medical University, Lucknow, India Background/Aims: Chronic pain has been recognized as a public health priority and is often associated with memory and concentration difficulties.1 (Brain 2013; 136, 815-827). The patients with irritable bowel syndrome (IBS) are characterized by chronic and recurrent abdominal pain. Whether there is any memory dysfunction exists in the IBS patients remain unclear. The aim of this study was to explore the memory function in IBS patients using questionnaire survey. Methods: Twenty-three IBS patients, 26 age- and education-matched controls were enrolled. Demographic data as well as hospital anxiety and depression scale (HADS), Pain Catastrophizing Scale (PCS), IBS Quality-of-Life questionnaire (IBS-QOL) and meta-memory in adulthood (MIA) questionnaire were assessed. In MIA questionnaire, which assessed beliefs about four aspects of memory function including memory capacity, knowledge, locus, and strategy. Result: IBS patients showed significantly higher levels HADS, PCS and IBS-QoL than control group. (all P < 0.05) Among the 4 aspects of MIA questionnaire, IBS patients reported lower memory capacity (56.8 ± 1.2 vs 53.4 ± 1.4, P = 0.05) and strategy (69.5 ± 1.9 vs 61.9 ± 2.0, P = 0.01) than control group, while memory knowledge and locus showed similar levels as the controls. PCS scores in IBS patients were negatively correlated with memory capacity (r = −0.391, P = 0.03). Conclusions: Memory impairment may be a common, but neglected, component of IBS. Chronic visceral pain may lead to parahippocampal dysfunction and contribute to memory impairment in IBS patients. Further elucidation of the neural dysconnection underlying the memory dysfunction may provide a better understanding of pathophysiology of IBS. Reference 1.

Background/Aims: Rectal prolapse is a debilitating condition that greatly impairs the quality of life. Multitude of surgical interventions has been developed for it’s management but the ideal treatment still remains far-fetched. We hereby report the intermediate-term outcomes of patients who underwent laparoscopic ventral mesh rectopexy for complete rectal prolapse. Methods: This study was conducted at a single tertiary care institution. Fifteen patients (7 males and 8 females) with a median age of 38 years (range 15-68 years) underwent laparoscopic ventral mesh rectopexy for complete rectal prolapse. Seven of these patients had associated fecal incontinence of varying degree. Four patients had complains of chronic constipation in the pre-operative period. Vault prolapse was present in 2 patients and one had coexisting inguinal hernia. The primary outcome measures were correction of anatomical defect and bowel dysfunction following the surgery and also detection of de novo functional problem in the follow-up. Results: The procedure was performed in 15 patients. All rectopexy procedures were done laparoscopically. Patients were followed-up for a median duration of 22 months (range 4-54 months). No peri-operative mortality occurred. One patient required re-exploration in the post-operative period due to inadvertent injury of the small bowel. No mesh-related complication was encountered. Till the last follow-up no recurrence was reported in any of the patient. All patients reported better bowel function and improved continence after the procedure. None of the patient had new onset of constipation or fecal incontinence following surgery. On personal interviews, all patients who underwent this procedure were satisfied with result of their surgery. Conclusions: Laparoscopic ventral mesh rectopexy appears to be a safe and effective alternative for the management of complete rectal prolapse. Lower recurrence rates, positive effect on functional bowel dysfunction and minimal complication makes this procedure “ideal” for management of rectal prolapse. S46 ANMA 2015 India Selected Poster Presentation No. 70 No. 72 Functional Dyspepsia Is Associated With GN3 C825T Polymorphism: A Case-control Study The Aaccuracy of Symptom Recall in Elderly Patients With Functional Constipation 1 2 Wenjuan Fan, Haiwei Xin, Shaomei Han, Jin Wang, Ying Ba, Jun Zhang, Shi Liu, and Xiucai Fang 1 Rajan Singh, Balraj Mittal, and Uday C Ghoshal 1 Department of Gastroenterology, Peking Union Medical College Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College, Beijing, China 2 Departments of Gastroenterology and Genetics, Sanjay Gandhi Postgraduate Institute of Medical Sciences, Lucknow, India Background/Aims: Functional dyspepsia (FD) is characterized by epigastric pain, burning, early satiety and post-prandial fullness in absence of organic or metabolic causes. Gastrointestinal (GI) motor abnormalities and altered visceral sensation have been considered as major pathophysiological mechanisms involved in FD. G-protein beta-3 subunit gene (GN3), C825T polymorphism alters intra-cellular signal transduction, which may lead to motor or sensory abnormalities of the GI tract. Therefore, we evaluated the role of this polymorphism in patients with FD as compared to healthy controls (HC). Methods: Two hundred thirty-seven consecutive patients with FD (Rome III) and 250 HC were genotyped for GN3 C825T polymorphism (PCR-RFLP). Patients with FD were sub-classified into epigastric pain syndrome (EPS), postprandial distress syndrome (PDS), and EPS-PDS overlap. Results: Patients with FD (173 [73%] male, age 38 ± 12 years) were comparable with HC (195 [78%] male, age 37 ± 12 years) with respect to age and gender. Twenty-six of 237 (11%) had EPS, 55 (23.2%) PDS, and 156 (65.8%) EPS-PDS overlap. Among 237 patients with FD, TT genotype (associated with increased intra-cellular signal transduction) of GN3 C825T polymorphism was commoner among patients than HC (26 [11%] vs 12 [4.8%], P = 0.014; OR, 2.47; 95% CI, 1.2-5.1). However, genotypes distribution was comparable among patients with different subtypes of FD (P = 0.800). Conclusions: TT genotype of GN3 C825T is commoner among patients with FD, suggesting that increased signal transduction associated with this genotype may be important in its pathophysiology. Background/Aims: The accuracy of symptom recall might influence the diagnosis of functional gastrointestinal disorders, including functional constipation (FC). The aim of this study is to evaluate the accuracy of the symptom recall in elderly patients with FC and its potential influence factors. Methods: Patients were ≥ 60 years old, met Rome Ⅲ-FC diagnostic criteria and had excluded organic diseases. At the beginning of the study, all subjects reported the duration of constipation, the frequency and severity of constipated symptoms during the past 3 months (recall symptoms), and then they take 2 weeks’ diary (diary symptoms). Symptom score was evaluated by the independent investigators. Patients were divided as mild, moderate or severe constipation group according to overall symptom score and subtyped into slow transit, defecation disorder, mixed and normal transit constipation based on the main symptoms, gastrointestinal transit time and anorectal manometry. The consistency of recalled symptoms and diary symptoms were analyzed. Results: One hundred and fifteen patients (55 males and 60 females) were enrolled from June, 2010 to October, 2012. The overall score of recall and diary symptoms are 27.57 ± 7.37 and 26.09 ± 7.59, respectively (P < 0.001). The recall symptom score has a correlation with diary symptoms (according to the severity of constipation, 2 χ test, к = 0.725, P < 0.001), and each recall symptom score has a correlation with diary symptoms (к > 0.75, P < 0.001). Gender, age, labor intensity, and economic situation (all P < 0.05) but not education level, duration, and severity of constipation, subtype of FC (all P > 0.05) influenced the accuracy of symptom recall. Female patients recalled severity of hard stools more accurately than male patients (P = 0.046). There is significant difference in recalled accuracy in numbers of defecations per week and sensation of anorectal obstruction among different age group (P < 0.05). Patients with good economic condition presented more accurate recall for frequency of hard stools than patients with lower income (P = 0.020). Conclusions: The accuracy of symptom recall in elderly patients with FC is acceptable even though gender, age, labor intensity and economic situation might influence the accuracy of some constipated symptom recall. S47 ANMA 2015 India Selected Poster Presentation 52.5%), abdominal discomfort (105 patients, 24.0%), incomplete bowel movement (31 patients, 7.1%), abdominal bloating (29 patients, 6.6%), straining (16 patients, 3.7%), fecal urgency (14 patients, 3.2%), heartburn (7 patients, 1.6%), and other symptoms (6 patients, 1.3%). The QOL of patients who could report the most bothersome were lower than healthy volunteers in both met and unmet the Rome III criteria (Table). All domains of QOL were not different between the patients who met and unmet Rome III criteria. The anxiety and depression scores were similar (8.0 ± 3.8 and 6.7 ± 2.5 vs 8.2 ± 4.5 and 7.2 ± 3.3) in these 2 FGID groups but significantly greater than healthy subjects (3.7 ± 2.7 and 3.4 ± 2.5, P < 0.001); the proportion of patients with anxiety and/or depression in the patients who met (186/310) and unmet (73/128) the Rome III criteria was also similar but significantly greater than healthy volunteers (15/120, P < 0.001). Conclusions: When approach to patients who present with any gastrointestinal symptoms using the Rome III criteria, the diagnosis could not be made in 29% of the patients but the symptom based diagnosis could be made in 100% of the patients. In addition, patients who had any bothersome symptoms both met and unmet Rome III criteria had similarly lower QOL and higher co-morbid anxiety and/or depression compared to healthy subjects. This study suggests that symptom based approach is likely to be more appropriate than Rome III criteria for approaching patients with any gastrointestinal symptoms in clinical practice. Clinical practice guideline should base on the most bothersome symptom instead of the Rome III criteria. No. 73 Comparison of Rome III Diagnostic Criteria Versus Simple Symptom Based Approach in Patients With Gastrointestinal Symptoms Presented at the General Medicine Clinic Kessarin Thanapirom, Tanisa Patcharatrakul, and Sutep Gonlachanvit GI motility Research Unit, Faculty of Medicine, King Chulalongkorn Memorial Hospital, Chulalongkorn University, Bangkok, Thailand Background/Aims: Rome III criteria have been used as standard tools for diagnosis of functional gastrointestinal disorders (FGIDs). However, the Rome III criteria have not been employed in most daily clinical practice. The aims of this study were to compare: (1) the proportion of patients who met the Rome III diagnostic criteria vs. symptom based diagnostic criteria, (2) the quality of life (QOL) in patients who met the Rome III criteria vs symptom based criteria in relative to healthy subjects, and (3) the proportion of co-morbid anxiety and depression in patients who met the Rome III vs symptom based criteria. Methods: Four hundred and thirty-eight patients (age 48 ± 13 years, 321 female) with any gastrointestinal symptoms without alarm features presented at General medicine Clinic, King Chulalongkorn Memorial hospital were invited to complete a Thai validated version of the FBDR3 questionnaire, the 36-item short form general health survey (SF-36), the hospital anxiety and depression scales (HADS) questionnaire. Symptom base diagnosis was based on the most bothersome symptom reported by the patients. Results: Three hundred and ten patients (70.8%) met Rome III diagnostic criteria (173 FD, 16 IBS, 74 FD + IBS, 27 functional constipation, and 20 other FGIDs) and 128 patients (29.2 %) unmet the Rome III diagnostic criteria. The reasons for unmet Rome III diagnostic criteria were symptom duration (108 and 3 patients experienced symptom duration 1-3 and 3-6 months, respectively) and incomplete symptom criteria (17 patients). All patients (100%) could report the most bothersome symptom including abdominal pain (230 patients, Table.

Thirty patients diagnosed of irritable bowel syndrome as per Rome III criteria and giving informed consent were assessed with Hamilton Rating Scale for Depression and Hamilton Rating Scale for Anxiety. Thirty age and sex matched healthy controls were also assessed using the same instruments. The results and discussion will be presented at the time of presentation Background/Aims: Though functional gastrointestinal disorders are common reasons for out-patient visit, there is scanty date on profile of these patients from India. Methods: Consecutive patients with functional gastrointestinal disorders (FGIDs) attending out-patient clinic of a medical college of eastern India were interviewed using a translated-validated Bengali questionnaires. Dyspepsia and irritable bowel syndrome (IBS) was defined according to Rome III criteria. Questionnaire also included the information about demography, socio-economic parameters, diet and psychological-comorbidity. Results: Of 1157 patients enrolled (age 31.2 ± 16 years, 673 [58.2%] male), 12.7% were in upper class, 11.5% upper middle, 8.5% lower middle, 14.5% upper lower, and 52.8% lower classes (Prasad socio-economic classification). Fifty-four of 1157 (4.7%) patients were vegetarian, 15 (1.3%) lacto-vegetarian, and 1088 (94%) non-vegetarian. Three-hundred forty of 1157 (29.4%) had dyspepsia, 98/1157 (8.5%) IBS, and 337/1157 (29.1%) dyspepsia-IBS overlap. In patients with dyspepsia, 76/677 (11.2%) had epigastric pain syndrome (EPS), 269 (39.8%) post-prandial distress syndrome (PDS) and 332 (49%) EPS-PDS overlap. Tobacco chewing (OR, 2.0; 95% CI,1.5-2.8; P < 0.001), high intake of tea/coffee (OR, 1.5; 95% CI, 1.1-2.0, P = 0.003), disturbed sleep (OR, 1.8; 95% CI, 1.4-2.3; P < 0.001) and anxiety (feeling of tension and wound up: 342/677 [50%] vs 168/480 [35%], worry: 414 (61%) vs 210 [43%], panic attacks: 448 [66%] vs 220 [45%], feeling of something awful: 308 [45%] vs 93 [19%], all P < 0.01) were associated with dyspepsia univariate analysis. Conclusions: Dyspepsia, particularly EPS-PDS overlap, was common in out-patient clinic; IBS overlap was also common among them. High intake of tea/coffee, tobacco chewing, disturbed sleep, and anxiety were associated with dyspepsia on univariate analysis.

This study was designed to see any relation of specific food items with IBS in North East part of Bangladesh. Methods: By randomized sampling method, subjects were selected in and around City corporation area of Sylhet district. People were interviewed from door to door with preformed questionnaire for IBS and food habit. Data was analyzed using SPSS 16. Results: Total 1900 (male 901, 47.4% and female 999, 52.6%) persons, age ranging from 15-92 years (mean 34.74 years), were interviewed. Prevalence of IBS was found 14.2%. IBS was more in older people (41.35 vs 33.65, P = 0.000), low education group (16.3% vs 7.9%, P = 0.000) and lower socioeconomic group (18.5% vs 9.2%, P = 0.000). House wives (15.0%), day laborer (17.8%), and farmers (16.9%) were more vulnerable to IBS. Among the food factors IBS was found more in those who consume spice regularly (18,8% vs 9.2%, P = 0.000) and in those who did not consume meat (18.7% vs 7.9%, P = 0.000), milk(16.8% vs 9.1%, P = 0.000), pulse (22.4% vs 10.5%, P = 0.000), fruit (17.8% vs 11.2%, P = 0.000) and tea (20.1% vs 12.7%, P = 0.000) frequently. Vegetables, wheat, smoking and chewing tobacco were not found to have significant associations with IBS. In multivariate analysis infrequent intake of meat (OR, 1.722; P = 0.002) and tea (OR, 1.735; P = 0.001) were found as important associated factors for IBS. Conclusions: Food factors found to have relations with IBS. Regular intake of tea and meat was found to have important negative associations with IBS symptoms. 2 3 Background/Aims: Irritable bowel syndrome (IBS) and migraine frequently co-exist. Stress is a major contributing factor for both. The study aimed to evaluate the prevalence of migraine, IBS and co-existing IBS and migraine among medical students. Methods: This questionnaire-based study was conducted among the students of 4 medical colleges. Migraine was defined according to International Headache Society criteria (IHS) while IBS by both Asian criteria and Rome III criteria. Results: A total of 293 students (mean age 21.09 years with SD 2.24 years) volunteered in the study (Male 177); 140 from private institutions and 153 from Government institutions. Fourteen (4.8%, 11 male, 3 female, P = 0.175) students met the criteria for IBS with comparable prevalence among preclinical and clinical (4.2% vs.5.3%, P = 0.787) students from both private and government institutions (2.1% vs. 7.2%, P = 0.055). IBS-D was the most prevalent subtype (n = 8, M = 6)), next common was IBS-M (n = 4, M = 3). Feeling of incomplete evacuation (n = 10), frequent motion (n = 7), straining (n = 7) and bloating (n = 7) were more prevalent symptoms besides abdominal pain relieved by defecation (n = 11). Fifty percent (n = 7) consider their bowel habit as normal. Among the 221 (75.4%) students with headache, only 83 (37.6%) had frequent attacks. Fiftyone (17.4%, 20 male and 31 female, P = 0.001) met the IHS criteria for migraine, with comparable prevalence among preclinical and clinical students (16.2% vs. 18.5%, P = 0.645). Ninety percent (n = 46) migraineurs had accompanying aura. Common triggers were stress (n = 43), lack of sleep (n = 42), and daily life events. Thirty-four (66.6%) migraine patients suffered frequent attacks and 12 (23.5%) had migraine-associated frequent disability. Headache was highly prevalent in IBS (n = 10, 71.4%) but only two female students with IBS-D (14.3%) had concomitant IBS and migraine. Conclusions: IBS and concomitant migraine - IBS prevalence was found to be low in our medical students, but migraine prevalence corresponds to other countries as well as in medical students.

Golam Kibria, Mohammed Masudur Rahman, Uday Chand 2 1 1 1 Ghoshal, Faruque Ahmed, Nigar Sultana, Mahfuza Akhter, Mahmud Hasan3 Yan Chen, Hai Li, and Shi Liu 1 Departments of Gastroenterology, Dhaka Medical College and Hospital, 2 Dhaka, Bangladesh; Sanjay Gandhi Postgraduate Institute of Medical 3 Sciences, Lucknow, India; and Bangladesh Medical Research Council, Dhaka, Bangladesh Division of Gastroenterology, Union Hospital, Tongji Medical College, Huazhong University of Science and Technology, Wuhan, China Background/Aims: Loss of interstitial cells of Cajal (ICC) has been confirmed in the stomach of diabetic patients, which leads to kinds of gastrointestinal motility disorders. Long pulse gastric electrical stimulation (GES) has been proved to improve gastric motility, but the mechanism is not completely understood. The aim of this study was to investigate the effect of long pulse GES on ICC and the related mechanism in diabetic rats. Methods: Male SD rats were randomized into the control, diabetic rats (DM), diabetic rats with sham GES (DM+SGES), diabetic rats with GES group (DM + GES1: 5.5 cpm, 100 msec, 4 mA; DM + GES2: 5.5 cpm, 300 msec, 4 mA; DM + GES3: 5.5 cpm, 550 msec, 2 mA). GES was performed 30 minutes everyday for 6 weeks. Mechanical contraction of gastric antrum was explored by organ bath technique. Western blot and RT-PCR were employed to demonstrate the expression of c-kit, a-SMA, and myosin 11 in gastric antrum. The distribution of ICC and smooth muscle cells (SMC) were identified by immunolabeling for c-kit and a-SMA. The ultrastructural alterations of ICC and SMC were reflected by transmission electron microscopy. Results: (1) In DM group, contractions of gastric antrum circular strips were severely weakened, while long pulse GES strengthened the attenuated contractions. (2) Both western blot analysis and RT-PCR suggested that the expression of c-kit was reduced apparently in DM group, but was obviously upregulated in GES group. Whereas the expression of a-SMA was not changed dramatically in each group, the expression of myosin 11 was decreased in DM group and markedly increased in GES group. (3) In DM group, c-kit positive cells distributed among SMC were significantly decreased. However, c-kit+ cell in GES group were rich both in muscular and intermuscular layer. (4) In contrast to the control group, the ultrastructural alterations of ICC and SMC in DM group were significantly destroyed. However, GES improved the ultrastructural alterations of ICC and SMC. Conclusions: Long pulse GES promoted the renovation of interstitial cells of Cajal, which may be related to smooth muscle cells in the stomach of diabetic rats. Background/Aims: Stool form and frequency, which are important to define constipation and diarrhea, may vary in different population. Data on stool form and frequency among Asian population are scanty. Accordingly, we undertook such a study in a rural Bangladeshi population. Methods: A door-to-door survey was conducted by trained interviewers among all the adults (> 18 years) living in a village (Charcharia, Dhaka District) in Bangladesh using a translated validated Bengali questionnaire. Data on demographic variables, stool form (Bristol stool scale [BSS]) and frequency were collected. Results: Of 1021 subjects invited in the study, 817 (80.0%, age 40.13 ± 15.53 years, 517 [63%] female) responded. Stool frequency was 9 ± 3.7 per week (median 7, range 0-28). Daily stool frequency was at least once a day in 747 (91.4%); 252 of these 747 (33.7%) subjects passed two to three stools a day. Weekly stool frequency was lesser among female compared to male (8.67 ± 3.5 vs 9.56 ± 3.9, P= 0.001). Only 6 (0.7%) subjects reported a stool frequency less than 3 times per week. Four (0.5%) subjects passed more than 21 times per week. Of 797 subjects who reported data on predominant stool types (BSS), these were: type IV 446 (55.9%), III 204 (25.6%), II 66 (8.3%), I 8 (1%), V 38 (4.8%), VI 28 (3.5%), and VII 07 (0.9%). Conclusions: Most people in Bangladeshi rural community passed more than one stool a day with a median frequency of seven per week. Common stool forms were Bristol type IV and III. Stool frequency was lower among female. S51 ANMA 2015 India Selected Poster Presentation No. 90 No. 92 A Disintegrin and Metalloproteases Expression in Functional Dyspepsia Patients With Helicobacter pylori Infection Melatonin Protects Esophageal Epithelial Barrier via Suppressing the Transcription, Expression and Activity of Myosin Light Chain Kinase Through ERK1/2 Signal Transduction 1 1 1 Jahanarah Khatoon, Kashi Nath Prasad, Ravi Prakash Rai, Narendra 2 3 Krishnani, and Uday Chand Ghoshal Departments of 1Microbiology, 2Pathology, and 3Gastroenterology, Sanjay Gandhi Post Graduate Institute of Medical Sciences, Lucknow, India Jiacheng Tan, Ying Wang, Xiaomeng Sun, Ting Yu, and Lin Lin Background/Aims: Helicobacter pylori infection is an important risk factor for development of various gastroduodenal pathologies including gastric cancer (GC). The bacterial-epithelial cell interactions may be critical in gastric pathogenesis. A disintegrin and metalloproteases (ADAMs), family of membrane anchored glycoproteins are thought to be responsible for ectodomain shedding of many membrane proteins like growth factor (EGFR), TNF-, cytokine, cytokine-receptors, etc. This ADAMs- mediated ectodomain shedding is likely to have a key role in inflammatory and pathological states. The objectives of this study was to detect- to detect the expression of ADAMs 10 and 17 in presence of H. pylori in patients of functional dyspepsia (FD). Methods: A total of 80 patients with functional dyspepsia (H. pyori positive 36 and H. pyori negative 44) patients were included in this study. Further, RNA was extracted from gastric biopsies and expression of ADAMs 10 and 17 were examined by quantitative real time PCR. Results: Present study revealed that the expression of ADAM17 was significantly higher (5.11 ± 4.00 vs 2.29 ± 2.85, P = 0.040), whereas the expression of ADAM10 tended to be higher (3.70 ± 6.24 vs 2.07 ± 2.50, P = 0.075) in patients with H. pylori infection. Conclusions: The study showed that in human gastric mucosal expressions ADAMs 10 and 17 were higher in patients with H. pylori infection. Further studies are needed to explore the exact role of ADAMs expression and functions of its various domains in pathogenesis of gastro-duodenal diseases in presence of H. pylori. Department of Gastroenterology, the First Affiliated Hospital of Nanjing Medical University, Nanjing, China Background/Aims: Dilated intercellular spaces (DIS) is a pathogenesis of gastroesophageal reflux disease (GERD). Myosin light chain kinase (MLCK) plays a role in maintaining epithelial cells morphology. Melatonin (MLT) protects esophageal mucosa against various types of injury, but its mechanism remains unclear. This study aimed to investigate the effects of melatonin on the esophageal epithelial barrier. Methods: Intercellular spaces in the esophageal epithelium of GERD patients were evaluated by transmission electron microscopy (TEM). The barrier function of Het-1A monolayer was investigated by measuring the transepithelial resistance (TER) and the paracellular permeation of FITC-dextran. The MLCK mRNA was measured by real-time PCR. The activity of MLCK was represented by the phosphorylation of MLC. The expression and phosphorylation of MLCK, MLC, and extracellular signal-regulated kinase (ERK) were examined by using western blotting. Results: Intercellular spaces of the esophageal epithelium were dilated significantly in GERD patients. The expression and activity of MLCK as well as the phosphorylation of ERK were increased in the esophageal epithelium. The increase in the expression and activity of MLCK were strongly correlated with dilated intercellular spaces. Upon acid treatment, the permeability of Het-1A monolayer was increased. The transcription, expression and activity of MLCK as well as the phosphorylation of ERK were up-regulated. When Het-1A monolayer was pretreated with melatonin and PD98059 (an inhibitor of ERK) before acid incubation, the permeability was decreased as well as the expression and phosphorylation of MLCK and ERK. Conclusion: Melatonin protected the esophageal epithelial barrier function via suppressing the transcription, expression and activity of MLCK through ERK1/2 signal transduction. These findings provided a better understanding of potential clinical application of melatonin in GERD treatment. S52 ANMA 2015 India Selected Poster Presentation No. 93 No. 95 Meta-analysis: The effect of Helicobacter pylori Eradication Therapy on The Development of Gastroesophageal Reflux Disease Effects of Acupuncture on Esophageal Motility in Patients With Refractory Gastroesophageal Reflux Disease Jiacheng Tan Department of Gastroenterology, Ruijin Hospital, Shanghai Jiaotong University School of Medicine, Shanghai, China Tang Yuming, Lin Han, Yao Weiyan, and Yuan Yaozong Department of Gastroenterology, the First Affiliated Hospital of Nanjing Medical University, China Background/Aims: To investigate the effects of acupuncture on improvement of esophageal motility disorder in patients with refractory gastroesophageal reflux disease (GERD). Methods: Forty patients with refractory GERD from the outpatient department of gastroenterology in Ruijin Hospital were included in this study from September 2012 to March 2014. The patients were evenly divided into the treatment group and the control group. High resolution esophageal impedance manometry was conducted in patients. After the manometry, patients of the control group lay for 30 minutes and patients of the treatment group received acupuncture at the selected points: Neiguan, Gongsun, and Zusanli for 30 minutes. Then all the patients underwent high resolution esophageal impedance manometry again. ManoView ESO 3.0 software was used for analysis. The parameters included lower esophageal sphincter (LES) pressure , swallowing peristalsis defect, LES residual pressure, LES length, upper esophageal sphincter pressure, distal wave amplitude, peristalsis duration time, starting speed of peristalsis wave, speed of edge contraction, and integration of the peristaltic waves. Chi-square test and t test were performed for data analysis. Results: The percentage of normal swallows of the treatment group before and after treatment was 56.0% (112/200) and 74.0% (148/200), while the percentage of delayed esophageal emptying was 31.5% (63/200) and 11.5% (23/200) and the differences were statistically sig2 nificant (χ = 14.242 and 23.700, both P = 0.05). The LES resting pressure of the treatment group before and after treatment was 20.4 ± 11.0 mmHg (1 mmHg = 0.133 kPa) and 19.8 ± 11.3 mmHg. The length of LES was 2.3 ± 0.6 cm and 2.5±0.6 cm. The distal esophageal peristaltic amplitude were 67.4 ± 21.2 mmHg and 53.5±18.1 mmHg, and the differences were statistically significant (t = 5.519, 6.580, and 6.881, all P = 0.050). While, before and after lying down, there were significant differences in the length of LES (2.2 ± 0.6 cm vs 3.3 ± 0.8 cm) and upper esophageal sphincter resting pressure (60.2 ± 21.9 cm vs 41.1 ± 16.8 mmHg) (t = 2.530 and 6.652, both P = 0.050). Conclusions: Acupuncture can help increase the LES resting pressure and the length of LES, improve the overall peristaltic pressure and completeness of esophageal somatic part, and increase the percentage of normal swallows of patients with refractory GERD. Background/Aims: It is uncertain whether the Helicobacter pylori eradication therapy makes a role in the progression of gastroesophageal reflux disease (GERD). Methods: A meta-analysis was undertaken to investigate the effect of H. pylori eradication therapy on the development of GERD. Results: Overall, 16 cohort studies were included. We demonstrated that H. pylori eradication had no significant effect on the occurrence of GERD in these cohort studies (OR, 0.87; 95% CI, 2 0.66-1.14; I = 32.4%; P = 0.103). Conclusions: In general, H. pylori eradication has no significant effect on the development of GERD in the long term. However, eradication therapy should be cosidered. Because H. pylori infection is acknowledged to be a major cause of acute and chronic gastritis and peptic ulcer diseases, and has been established as a definite etiological factor for gastric cancer. S53 ANMA 2015 India Selected Poster Presentation No. 97 No. 99 Upper Esophageal Sphincter Function During Transient Lower Esophageal Sphincter Relaxations in Gastroesophageal Reflux Disease Patients: Based on Impedance-High Resolution Manometry Results Is There Any Correlation Between Gastroesophageal Reflux Disease and Atrial Fibrillation? Jae Jin Hwang, Dong Ho Lee, Ae-Ra Lee, Yong Hwan Kwon, Yeon Sang Jeong, Hyun Joo Lee, KiChul Yoon, Hyuk Yoon, Cheol Min Shin, Young Soo Park, and Nayoung Kim Jingzhi Zhang, Xuelian Xiang, Xiaoping Xie, and Xiaohua Hou Department of Internal Medicine, Seoul National University Bundang Hospital, Seongnam, Gyeonggi-do, Korea Division of Gastroenterology, Union Hospital of Tongji Medical College, Huazhong University of Science and Technology Background/Aims: Recent studies have reported an association between Gastroesophageal reflux disease (GERD) and atrial fibrillation (AF). The objective of the present study was to determine the association of GERD with AF. Methods: In this retrospective study, patients with newly diagnosed with GERD or AF were classified into two groups. The patients diagnosed as new GERD with the presence of AF were assigned to the GERD group (n = 129), and those diagnosed as new AF with the presence of GERD were assigned to the AF group (n = 134). The risk factors of 2 groups were then correlated respectively. Results: In univariate and multivariate analyses, age, alcohol, underlying chronic obstructive pulmonary disease, coronary artery disease, thyrotoxicosis, use of angiotensin-converting enzyme inhibitor, B-blocker, and warfarin were related to the incidence of GERD in the GERD group (P < 0.05). In the AF group, chronic obstructive pulmonary disease and proton pump inhibitors were related to the incidence of new AF (P < 0.01). The presence of AF was found to increase the risk of GERD (RR, 1.37; 95% CI, 1.33-1.47; P = 0.004), and conversely, the presence of GERD was determined to increase the risk of AF (RR, 1.12; 95% CI, 1.08-1.19; P = 0.005). Conclusions: There was a significantly strong association between GERD and AF. The presence of GERD or AF increased the risk of diagnosis of the other. Further, large prospective and cohort studies will be required to better establish the association of GERD with AF. S54 ANMA 2015 India Selected Poster Presentation No. 100 No. 101 Predictors of Long-term Proton Pump Inhibitor Use in Patients With Suspected Laryngopharyngeal Reflux Who Responded to Proton Pump Inhibitor Therapy Non-cardiac Chest Pain With Normal Endoscopy: Role of Manometry and pH Recording in Indian Setting Han-Chung Lien, Chen-Chi Wang, Chi-Sen Chang, Wen-Miin Liang, Jeng-Yuan Hsu, and Hong-Zen Yeh Choithram Hospital and Research Centre, Indore, India Mayank Jain Han-Chung Lien, Division of Gastroenterology, Taichung Veterans General Hospital, Taichung, Taiwan; Department of Internal Medicine, National Yang-Ming University, Taipei, Taiwan; and Department of Public Health, China Medical University and Hospital, Taichung, Taiwan Background/Aims: Laryngopharyngeal reflux (LPR) is a chronic relapsing disease. The long-term outcome is unknown. We aimed to find the predictors of long-term proton pump inhibitors (PPIs) users among initial responders for LPR symptoms. Methods: A total of 51 subjects with predominant laryngeal symptoms suggestive of LPR who responded to a 12-week twice daily esomeprazole therapy between 2006 and 2009 were enrolled. We followed up symptoms and PPIs use periodically. Factors associated with requirement of long-term PPIs use more than 1 year after initial diagnosis were analyzed. Results: Two subjects were excluded from analysis because of concern about the safety of long-term PPI use. The median follow-up period for the remaining 49 subjects were 5 years. Thirty one (63%) of subjects remained symptomatic for larynx. Thirty-five (71%) of subjects required long-term PPIs therapy (twice daily in 2, once daily in 11, and on-demand in 22). The pre-treatment excessive distal esophageal acid exposure (71.4% vs 14.3%, P < 0.001), pharyngeal acid exposure (42.9% vs 7.1%, P = 0.02), either of above parameters (85.7% vs 14.3%, P < 0.001), and the presence of reflux esophagitis (31.4% vs 0.0%, P = 0.020) but not typical reflux symptoms (65.7% vs 64.3%) predicted the long-term PPIs use. Conclusions: The majority of patients with suspected LPR who responded to initial PPI therapy remained symptomatic and still required PPI therapy for median follow-up of 5 years after diagnosis. Approximate 27% of subjects still required regular PPI therapy at least once daily. The baseline pH test and reflux esophagitis, but not typical reflux symptoms were predictive factors of those who required long-term PPI therapy. S55 Background/Aims: To determine the common endoscopic and manometric changes noted in patients presenting with non-cardiac chest pain (NCCP) and to identify role of manometry and pH recording in Indian patients. Methods: The study was done at Choithram Hospital and Research Centre, Indore. The study duration was from October 2011 to October 2013. All patients who had significant retrosternal chest pain and whose cardiology evaluation was negative (normal ECG, TMT, and/or 2D-echo, angiography in selected cases) formed the study group. Upper gastrointestinal endoscopy was done in all patients. If normal, they were subjected to high resolution esophageal manometry. Reporting was done as per Chicago classification. 24-hour pH recording was done as and when required. Results: A total of 126 patients (mean age of 45.4 years, 84 males, 42 females) formed the study group. Two thirds of the patients had abnormalities in the esophagoduodenoscopy. In the remaining 42 patients, esophageal manometry was done. The findings included normal manometry (22), type 3 achalsia cardia (2), nutcracker esophagus (2), diffuse esophageal spasm (4), and hypotensive lower esophageal sphincter with weak peristalsis (12).Twenty hour pH recording was done in 24 patients out of 34 patients who had no characteristic dysmotility pattern. In 16 patients, acidic reflux with good symptom correlation was noted. In the other 8, 6 had significant acidic reflux with poor symptom correlation and 2 had no significant acidic reflux. Conclusion: Two thirds of patients with NCCP have endoscopic findings. In patients with non cardiac chest pain and normal endoscopy, manometric evaluation and 24-hour pH recording help to establish diagnosis in majority of the cases. Hence, in resource limited countries like India, I would like to recommend manometry and pH recording in only patients who have normal endoscopies. ANMA 2015 India Selected Poster Presentation No. 103 No. 104 Symptoms and Quality of Life in Patients With Gastroesophageal Reflux Disease and Therapeutic Response to Rabeprazole Foods Reproducing Typical Gastroesophageal Reflux Disease Symptoms in Korea Dashatwar PD, Nitesh Pratap, Sharat Reddy Putta, and Nagarjuna Yarlagadda Yong Jeoung, Jung Wan Choe, Moon Kyung Joo, Hyo Jung Kim, Beom Jae Lee, Jong-Jae Park, Jae Seon Kim, and Young-Tae Bak Department of Gastroenterology, Krishna Institute of Medical Sciences, Karad, Maharashtra, India Department of Gastroenterology, Korea University Guro Hospital, Seoul, Korea Background/Aims: Gastroesophgeal reflux disease (GERD) is a one of the commonest GI disorders with a great impact on quality of life of GERD patients. Health-related quality of life (HRQL) is emerging as an important factor in selecting treatment options and in assessing the outcome of different treatment strategies. Studies suggest that rabeprazole is one of the most potent drugs in the treatment of GERD with excellent safety profile. Quantification of real-life outcomes of treatment of GERD with rabeprazole using questionnaire based indices. Methods: Fifty-two consecutive patients with symptoms suggestive of GERD were evaluated with endoscopy. The cases were classified into either erosive esophagitis or non-erosive esophagitis. All such patients were enrolled in the study and before starting rabeprazole treatment HRQLI and Reflux severity index (RSI) were calculated. Patients were reassessed with same questionnaires after 45 days of therapy. Paired t test was used to determine the P-value. Results: Mean scores of pre-treatment HRQLI and RSI for patients were 26.72 ± 8.29 and 29.72 ± 7.72 respectively. After 45 days of treatment HRQLI and RSI showed significant decline to 12.10 ± 5.35 and 12.47 ± 4.31 (P < 0.001) respectively. Treatment with rabeprazole showed significant improvement in epigastric pain, regurgitation, and quality of sleep. Conclusion: Rabeprazole demonstrated excellent efficacy in controlling GERD symptoms. Background/Aims: Limitation of quality of life in gastroesophageal reflux disease (GERD) patients is mainly due to their subjective symptoms, not complications. Several specific foods, including dietary fat, chocolate, mints, coffee, spicy foods, citrus fruits, and tomatoes, have been known to be precipitate GERD symptoms and the GERD patients are usually advised to avoid such foods. Avoiding such foods may be important in keeping the patients in silent state after medications, although it may not be helpful to induce the healing of GERD. However, foods consumed daily are quite variable according to the regions, cultures, etc. Therefore, dietary advices should be based on local experiences. This study was done to elucidate what kind of foods may be responsible to induce typical GERD symptoms in Korean patients in daily life. Methods: Korean patients having typical GERD symptoms (heartburn or regurgitation) at least once a week were asked to mark all food items that induced their typical GERD symptoms for the last 3 months from a food list containing 152 typical foods consumed daily in Korea. If they had any symptom-inducing food(s) but could not find it (or them) on the list, they were instructed to add it (or them) to the list. The accused food items were categorized into 2 groups; “frequent” if any food induced symptom(s) in half or more occasions of consumptions and “occasional” if it induced symptom(s) in less than half occasions. In addition, they were asked to delete all uncertain foods from the list because they had not taken such food for the last 3 months. Foods inducing typical GERD symptom(s) in 50% or more patients of the group were regarded as meaningful. All patients underwent upper gastrointestinal endoscopy and ambulatory pH (with/without impedance) monitoring, and they were divided into 2 groups according to the results; “GERD” if either study revealed evidence of GERD and “possible GERD” if both studies were negative. Results: One hundred and twenty-six patients (51 GERD and 75 possible GERD) were enrolled. Nineteen (37.3%) of GERD patients and 17 (22.7%) of possible GERD patients indicated specific food items inducing their typical GERD symptoms. In GERD group (n = 19), foods frequently inducing typical GERD symptoms were hot spicy stew, rice cake, ramen noodle, fried food, and topokki (stir-fried spicy rice cake). Foods frequently or occasionally inducing symptoms were hot spicy stew, ramen noodle, fried food, rice cake, biscuit, bread, S56 ANMA 2015 India Selected Poster Presentation sujebi (clear soup with dumplings), topokki, hamburger, doughnut, chanpon noodle, jajangmyeon (noodle with salty black soybean sauce), alcoholic beverage, Fanta, pizza, mandarin, plain noodle, orange, mandarin juice, and milk. In possible GERD group (n = 17), foods frequently inducing typical GERD symptoms were hot spicy stew, fried food, doughnut, bread, ramen noodle, coffee, pizza, topokki, rice cake, chanpon noodle, and hotdog. Foods frequently or occasionally inducing symptoms were fried foods, hot spicy stew, topokki, bread, pizza, rice cake, coffee, doughnut, ramen noodle, hotdog, cola, orange juice, chanpon noodle, alcoholic beverage, orange, hamburger, jajangmyeon, sujebi, dumpling, red bean, green tea, and rice cake soup. In all confirmed or possible GERD patients (n = 36), foods frequently inducing typical GERD symptoms were hot spicy stew, rice cake, ramen noodle, fried food, bread, and topokki. Foods frequently or occasionally inducing symptoms were hot spicy stew, fried food, ramen noodle, rice cake, bread, topokki, pizza, doughnut, coffee, sujebi, chanpon noodle, hamburger, alcoholic beverage, jajangmyeon, orange, biscuit, cola, orange juice, and plain noodle. Conclusions: Hot spicy stew, rice cake, ramen noodle, fried food, and topokki are foods frequently reproducing typical GERD symptoms in Korea. The list of food items reproducing typical GERD symptoms in Asian countries is needed to be revised substantially from that of the Western literature based on the local experiences. No. 105 An Open Label, Non-randomized, Prospective Comparison of the Efficacy of Ilaprazole and Esomeprazole in the Treatment of Gastroesophageal Reflux Disease Ayesha Siddiqua, Madiha Ahmed, Nitesh Pratap, Dashatwar PD, and Sharat Reddy Putta Department of Gastroenterology, Krishna Institue of Medical Sciences, Karad, Maharashtra, India Background/Aims: Proton pump inhibitors (PPIs) are widely used for the treatment of gastroesophageal reflux disease (GERD). The available PPIs differ somewhat in their pharmacokinetics and clinical properties, but whether these differences are of clinical relevance is a matter of debate. Esomeprazole, the S-isomer of omeprazole, has established pharmacological and clinical benefits beyond those seen with the racemic parent compound - omeprazole. Preclinical studies have found ilaprazole to be significantly effective in treatment of reflux oesophagitis and suppression of gastric secretion in a dose-dependent manner; the drug also has a broad dose range and safety feature. Till date only one clinical study on patients with GERD has shown its potency in suppressing gastric acid secretion. To compare the efficacy of esomeprazole and ilaprazole with regards times to first response after treatment and complete clinical remission of symptoms. Methods: Esomeprazole 40 mg once daily (qd) (Neksium; n = 15) and ilaprzole 10 mg qd (Adiza; n = 15) were administered to consecutive patients with signs and symptoms suggestive of GERD, irrespective of endoscopic findings of erosive or non-erosive reflux disease. Patients were followed up for minimum period of 4 weeks and time to of heartburn after administration of either drug and the time to the complete symptomatic remission, if any, were noted with the help of a questionnaire. Results: All patients had symptomatic remission at the end of four week period. Difference in time to relief of heartburn was statistically insignificant for both PPIs (esomeprazole [4.072 ± 0.753] hours and ilaprazole [4.129 ± 0.731] hours, P = 0.836). Likewise, time to complete clinical remission was similar for both the drugs (esomeprazole [6.867 ± 4.422] hours and ilaprazole [6.267 ± 4.480] days, P = 0.736). Conclusions: Ilaprazole 10 mg qd for 4 weeks is effective therapy for GERD, and it was equivalent to esomeprazole 40 mg daily in terms of time to initial symptom relief and complete symptomatic remission. S57 ANMA 2015 India Selected Poster Presentation No. 106 No. 108 Effect of Non Absorbable Antibiotic, Rifaximin in Patients With Irritable Bowel Syndrome: A Single Centre Study Effect of DA-9701 on Visceral Pain in Rats Dae Sung Lee Department of Gastroenterology, Internal medicine, Sungkyunkwan University Kangbuk Samsung Hospital, Seoul, Korea Ramesh M, Bhagyalekshmi N, and J Xavier Ignatius MES Medical College, Perinthalmanna, Malapuram, Kerala, India Background/Aims: DA-9701 is a compound extracted from Corydalis Tuber and Pharbitidis Semen. It promotes gastric emptying and facilitates gastric accommodation. It has antiacetylcholine-esterase, antibutylcholine-esterase, antiallergic activity and antinociceptive activity. Mechanisms of analgesic effect of DA-9701 are by 5-hydroxytryptamine agonist/antagonist and D2 agonist. It is used for the treatment of functional dyspepsia. The heterogeneous symptom and multiple causes of functional dyspepsia have resulted in multiple drug target strategies for its treatment. In this study, we examined the antinociceptive effect of DA-9701 using intraperitoneal acetic acid injection in rat model. Methods: After injection of acetic acid to intraperitoneal cavity, writhing behavior was checked as response to the pain. Writhing test is the most common behavior test for visceral pain in animal model. Intraperitoneal injection of acetic acid solution was used to make visceral pain. Ten milligram per body weight (kg), 0.6% solution of acetic acid was injected to intraperitoneal cavity of rat. DA-9701 was dissolved in saline and injected to intraperitoneum. Two different dose of DA-9701 was injected to each study group, 3 and 10 mg/kg, respectively. Writhing behavior was checked every 5 minutes. Saline was injected to the control group instead of acetic acid. Results: Eight rats were tested at each study group. Ten milligram per kilogram of DA-9701 makes decreased writhing behavior compared with other 2 groups in rats. P value of 10 mg/kg of DA-9701 compared with other 2 groups was 0.001 and 0.021, respectively, at 0 to 5 and 30 to 35 minutes. P value was 0.152 and 0.113 at 10 to 15 and 20 to 25 minutes, respectively. There is difference in number of writhing behaviors induced by acetic acid between saline and DA-9701 injected rats. Conclusions: DA-9701 is effective in visceral pain induced by inflammation or irritation of abdominal cavity. But further study is needed to evaluate DA-9701 effect. Background/Aims: Irritable bowel syndrome (IBS) is the most common functional bowel disease having a great impact on quality of life. Recent studies suggest the role of infective etiology. Recently there are many studies addressing the role of rifaximin in IBS, however there are no such studies available from India. In this study we are demonstrating the effect of rifaximin, a non absorbable antibiotic, in IBS. Our objective is to assess the efficacy and safety of short course of rifaximin in IBS patients without constipation. Methods: This randomized controlled study was carried out in a tertiary care hospital in Kerala. Study period was 12 months. IBS was diagnosed using Rome III criteria. Patients were divided into treatment group and placebo group using simple systematic randomization. Treatment group received rifaximin 400 mg thrice daily for a period of 2 weeks and all patients were subsequently followed up to one week. In addition to clinical and laboratory parameters patients subjective feeling of well being also recorded before treatment, end of the treatment and at the end of 1 week the follow up period. Subjective feeling of improvement in global IBS symptoms, bloating score, pain score, and overall score was used in final analysis. Analysis was done using SPSS version 16. Results: A total of 149 patients were analyzed; 75 patients in rifaximin group and 74 patients in control group. Baseline characteristics were comparable in both groups. There was a significant reduction in global IBS symptoms in rifaximin arm when compared to control group (68% vs 39.1%, P < 0.001). Assessment at the end of 2 weeks therapy rifaximin provided significant improvement in the following IBS related symptom scores (bloating score, pain score, and overall score). Improvement in consistency of stool and stool frequency was also observed in rifaximin arm compared to control arm. The improvement which was obtained at the end of the treatment was sustained for one week of follow up period. There were no significant differences in laboratory parameters between 2 groups after treatment. No major adverse effect was reported during study and minor adverse effects were comparable in both groups. Conclusions: A 2 weeks course of rifaximin in IBS patients provided significant improvement in global IBS symptoms. Patients who received rifaximin had improvement in IBS related scores; such as bloating score, pain score, and overall score. No major adverse effect was reported in the study. Minor adverse effects were comparable in both rifaximin and control group. S58 ANMA 2015 India Selected Poster Presentation No. 109 No. 110 Toll Like Receptors 4 and 5 but Not 2 mRNAs Are Over-Expressed in Colonic Biopsy Among Patients With Irritable Bowel Syndrome Up-Regulations of Gastric TRPV Receptors and Decreased Serum Concentration of BDNF in Patients with Functional Dyspepsia 1 1 2 Ujjala Ghoshal, Ratnakar Shukla, Vikas Agarwal, Tapan N Dhole, 3 and Uday C Ghoshal 1 Departments of 1Microbiology, 2Immunology, and 3Gastroenterology, Sanjay Gandhi Postgraduate Institute of Medical Sciences, Lucknow, India Cynthia K Y Cheung, Lin Lin Lan, Yawen Chan, and Justin C Y Wu Institute of Digestive Disease, The Chinese University of Hong Kong, Hong Kong, China Background/Aims: Immune activation has been implicated in the mechanism of post-infectious functional dyspepsia (FD). However, the role of immune activation in FD patients without infection remains unclear. To compare the gastric mucosal and serum expression of brain-derived neurotropic factor (BDNF), transforming growth factor beta (TGF-) families, and transient receptor potential vanilloid type (TRPV) families between FD patients and healthy controls. Methods: Consecutive adult FD patients (Rome III) with no recent history of gastroenteritis and age-and-sex matched asymptomatic healthy controls were recruited for upper endoscopy. Subjects with gastroesophageal reflux disease and irritable bowel syndrome as predominant symptoms, diabetes mellitus, current or previous Helicobacter pylori infection, psychiatric illness and recent use of NSAID or proton pump inhibitors were excluded. Serum and mucosal biopsies from the gastric corpus were obtained for quantitative assay of mRNA TRPV1, TRPV2, and TGF-1 by real time-polymerase chain reaction. Serum concentrations of TGF- families and BDNF were analyzed using immunoassay. The gastric mucosal inflammation was evaluated using Sydney classification. The associations between these assays and dyspeptic symptoms were evaluated. Results: Forty-five (M:F = 8:37, mean age 35.9 [9.1]) FD patients were matched with 23 healthy controls (M:F = 8:15, mean age 36.6 [10.2]] respectively. FD patients had postprandial distress syndrome as predominant sub-type (postprandial distress syndrome: 43, epigastric pain syndrome: 2). There was no significant difference in the median inflammation score between FD patients and controls (FD: 0 (0-1) vs Control: 0 (0-1), P = 0.540). However, FD patients had significantly higher mRNA expression of gastric TRPV1 (FD: 0.008 ± 0.002, control: 0.003 ± 0.001, P = 0.030), TRPV2 (FD: 0.006 ± 0.001, control: 0.002 ± 0.001, P = 0.010) and a trend of increased gastric TGF-1 (FD: 0.013 ± 0.003, control: 0.005 ± 0.002, P = 0.070) compared to controls. The serum concentration of BDNF (FD: 240.7 ± 11.0, control: 389.6 ± 22.7, P < 0.001) were significantly lower in FD patients. Serum TGF-1 and TGF-2 concentrations were significantly correlated with symptoms of belching (R = 0.441, P = 0.010) and vomiting (R = 0.378, P = 0.040) in FD patients. Conclusions: Despite the absence of gastric mucosal inflammation, up-regulations of gastric mucosal TRPV1, TRPV2, TGF-1, and down-regulation of serum BDNF were observed in FD patients. The immune activation is associated with symptoms of belching and vomiting. These findings suggest that mucosal immune activation also contributes to the development of FD in those without history of infection. Background/Aims: Evidence of low grade inflammation, increased intestinal permeability and altered host-microbial interactions suggests that innate immune response may play an imperative role in the pathogenesis of Irritable bowel syndrome (IBS), hitherto an enigmatic disorder. Since toll like receptors (TLR)s are important component of innate immune system. We aimed of study TLR-2, TLR-4, and TLR-5 expression in colonic biopsies among patients with IBS. Methods: Quantitative real-time polymerase chain reaction was used to determine the relative expression of mRNA of TLRs in colonic biopsy samples in 47 patients with IBS (Rome III criteria) and 30 controls. Results: Of 47 patients with IBS (comparable in age and gender with controls), 20 had constipation (IBS-C), 20 had diarrhea (IBS-D) predominant IBS; the syndrome could not be sub-typed (IBS-U) in 7 using Rome III criteria. Relative expression of TLR-4 and TLR-5 was up-regulated in patients with IBS compared to controls (TLR-4: [0.15 ± 0.06] vs [0.002 ± 0.001], P < 0.001; TLR-5: [3.14 ±1.02] vs [0.05 ± 0.17], P < 0.001). Expression of TLR-4 and TLR-5 was higher both among IBS-C and IBS-D as compared to controls (P < 0.001). Expression of TLR-2, however, was comparable ([0.06 ± 0.006) vs [0.05 ± 0.010], P = 0.089). Conclusions: Up-regulations of TLR-4 and TLR-5 in colonic biopsies among patients with IBS may suggest that innate immune response may play a potential role in the pathophysiology of IBS. S59 ANMA 2015 India Selected Poster Presentation No. 112 No. 113 Regulation of Esophageal Epithelial-derived Cytokines by IL-33 Prevalence and Symptoms Correlation of Lactose Intolerance in North East Part of Bangladesh Katsuyuki Tozawa, Tadayuki Oshima, Jing Shan, Takahisa Yamasaki, Takashi Kondo, Tomoaki Kono, Fumihiko Toyoshima, Hisatomo Ikehara, Yoshio Ohda, Toshihiko Tomita, Hirokazu Fukui, Jiro Watari, and Hiroto Miwa Division of Gastroenterology, Department of Internal Medicine, Hyogo College of Medicine, Nishinomiya, Japan Madhusudan Saha, Shasanka Saha, Bimal Chandra Shil, Irin Parveen, Monojit Majumder, and Ranjit Kumar Banik North East Medical College, Sylhet, Bangladesh Background/Aims: This study was designed to see the prevalence of lactose intolerance and symptom correlation following oral lactose tolerance test in healthy adult volunteers in the north east part of Bangladesh. Methods: apparently healthy volunteers underwent oral lactose tolerance test after overnight fasting. Blood glucose was measured at 0 hour and 30 minutes after 25 g oral lactose load. Failure to rise blood glucose level ≥ 1.1 mmol/dL at 30 minutes after lactose intake from fasting level was taken as lactose malabsorption ie, lactose intolerance. Results: A total 174 volunteers (male 126, female 48) with mean age 35.03 years participated in this study. Lactose intolerance was found among 83.9% (male 105, female 41). Symptoms mostly experienced by the lactose malabsorbers were diarrhea (n = 84, 57.53%), borborygmi (n = 81, 55.47%), abdominal pain (n = 39, 26.71%), and flatulence (n = 27, 18.49%). Conclusions: Lactose intolerance among healthy adults of North East part of Bangladesh is as common as in many countries in Asia including China and Malaysia. But it is higher than that of Europeans and also that of south Indians. Diarrhoea, borborygmi, abdominal pain, and flatulence are most common symptoms associated with lactose malabsorption. Background/Aims: IL-33 is a tissue-derived cytokine constitutively expressed in epithelial cells and plays a role in sensing damage caused by inflammatory diseases. We recently reported IL-33 in the esophageal mucosa is up-regulated in reflux esophagitis patients. However, the regulation of cytokines by IL-33 has not been examined. Accordingly, we examined the function of IL-33 in esophageal epithelial cells using normal esophageal squamous epithelial cells. Methods: Cytokines produced from esophageal biopsy specimen was determined by Bio-Plex system. Using an in vitro stratified normal esophageal squamous epithelial model, IL-33 production was assessed by western blotting and immunofluorescence staining. Cytokines produced by the cell layers after stimulations were measured by ELISA and Bio-Plex system. Pharmacological inhibitors were used to examine the regulation of cytokine productions by IFN. IL-33 siRNA was used to examine the function in esophageal epithelial cells. Results: Esophageal biopsy specimen produced IL-8 and IL-6. IFNg induced nuclear IL-33 expression and IL-33 mRNA dose and time dependent manner in stratified esophageal epithelial cell model. Furthermore, IFN- induced IL-8 and IL-6 release from the cell layers. IFN--induced IL-33 protein up-regulation in the cell layers was through Janus-activated kinase (JAK) and p38 mictogen-activated protein kinase (MAPK) activation, but not through protein kinase A (PKA). IFN--induced IL-8 and IL-6 release was JAK, p38MAPK, and STAT1 dependent. IFN--induced IL-8 and IL-6 are regulated by IL-33. Conclusions: Esophageal epithelial nuclear IL-33 is up-regulated by IFN- and inflammatory cytokines production from these cells is regulated by IL-33. S60 ANMA 2015 India Selected Poster Presentation No. 114 No. 116 Gastrointestinal Motility Disturbances In Patients With Celiac Disease Motility Disturbances in Achalasia Cardia Are Wide Spread in Gastrointestinal Tract 1 2 3 1 1 S K Sinha, H Sinha, A Bhattacharya, S V Rana, K K Prasad, C K 1 1 1 1 1 Nain, R Kochhar, R Prasada, D K Bhasin, and K Singh A Miglani, S K Sinha, BR Mittal, DK Bhasin, B Nagi, R Kochhar, HS Dhaliwal, and K Singh Departments of 1Gastroenterology, 2Internal Medicine, and 3Nuclear Medicine, Post Graduate Institute of Medical Education and Research, Chandigarh, India Departments of Gastronetorlogy and Nuclear Medicine, Post Graduate Institute of Medical Education and Research, Chandigarhg, India Background/Aims: In achalasia cardia, motility disturbances have been assumed to be confined to esophagus. However, losses of inhibitory ganglia into the proximal stomach and degenerative changes in ganglia of vagal dorsal motor nucleus have been reported. As whole of gastrointestinal tract (GIT) is supplied by vagus nerve, the motility disturbances may be widespread in GIT. Methods: This propective study included 20 patients of treated Achalasia cardia (post pneumatic dialtation and grade 0-1 dysphagia). Gastric emptying time for solids was measured by scintigraphic meth99m od using Tc sulphur colloid. Small intestinal transit time (SITT) was also measured by scintigraphic method. Ultrasound of gall bladder (GB) was done at baseline and after fatty meals (30 minutes and 60 minutes) to measure gall bladder ejection fraction. Results: In these 20 patients (13 males, age 36.9 ± 10.4 years) mean duration of dysphagia was 38.6 + 32.3 months. Gastric emptying T1/2 for solids and percentage emptying at 60 minutes were 87.4 + 47.1 minutes and 41.4 + 17.7% respectively. SITT measured by scintigraphic study was 4.6 + 1.56 hous. 35% patients had prolonged gastric emptying T 1/2 for solids (normal < 80 minutes) and 65% patients had reduced percentage gastric emptying at one hour (45%). Prolonged SITT (> 3.5 hours) was found in 75%. Mean GBEF at 30 and 60 minutes were 50.7 + 21.4 and 46.5 + 29.4% respectively. 40% patients had static GB (GBEF < 40%) and 20% had poor contractility of GB (GBEF 40-60%). Conclusions: In Achalasia cardia, altered gastric emptying, prolonged SITT and reduced GBEF was seen in most of the patients. Thus, GIT motility disturbances seem to be widespred among patients with Achalasia cadia. Background/Aims: Some of the symptoms of celiac disease patients suggest disturbances in gastrointestinal (GI) motility. In celiac disease, pathology mainly involves the epithelium and lamina propria. Involvement of muscle layer has not been clearly defined. The gut motility is primarily determined by muscularis propria and nervous system (enteric, autonomic, and central). There is paucity of data on motility changes in patients with celiac disease. To study esophageal, gastric and small intestinal motility in untreated cases of celiac disease Methods: This prospective study included untreated consecutive cases of celiac disease. Patients with any of following were excluded: unwillingness to participate, intake of antibiotics or drugs affecting GI motility in preceding 2 weeks, co-morbid illnesses affecting GI motility and pregnancy or lactation. Esophageal motility was studied by esophageal manometry performed by station pull through. Gastric motility was studied scintigraphically by measuring the rate of empty99m ing of solid meal. Patients were given 2 Idlis labeled with Tc sulphur colloid. Segmental dynamic images were acquired in supine position with a gamma camera for 1 hour @ 1 minute/frame. Standard software was used to calculate % emptying at 60 minutes and T1/2. Orocecal transit time was measured by lactulose hydrogen breath test. Breath hydrogen was measured using Quintron SC Microanalyser. After collecting fasting breath samples, 10 grams of lactulose was given orally. End expiratory breath samples were collected every 15 minutes for 180 minutes. Time taken for a sustained rise in breath hydrogen by > 10 ppm was taken as oro-cecal transit time. Results: Out of 56 new cases of celiac disease seen during the study period, 44 (21 males [47.7%]), age 28.1 ± 13.4 years) were included and 12 excluded. Esophageal manometry was performed in 38 cases and showed normal motility in 24 (63.2%), isolated hypertensive lower esophageal sphincter (LES) in 2 (5.3%), nut cracker esophagus in 1 (2.6%), nut cracker esophagus with hypertensive LES in 2 (5.3%), hypertensive LES with non-specific esophageal dysmotility in 3 (6.8%), and non-specific esophageal dysmotility with normal LES in 6 patients (15.8%). Gastric emptying for solids was found to be delayed in 13 out of 32 patients (40.6%). Orocecal transit time was prolonged in 25 out of 33 patients (75.8%). Conclusions: Esophageal, gastric, and small intestinal motility disturbances are common in untreated patients of celiac disease.

Methods: Three hundred and twenty-four consecutive RT recipients on immunosuppressive treatment and 170 healthy subjects were evaluated for intestinalmicrosporidiosis and other parasites using modified trichrome staining, wet mount using normal saline and iodine staining and polymerase chain reaction (PCR). Clinical, demographic and laboratory parameters associated with occurrence of intestinal microsporidiosis were studied using univariate and multivariate analysis. The species of microsporidia were studied using PCR-RFLP. Results: Of 324 RT recipients initially screened, 52 were excluded from final analysis due to incomplete data. Patients with RT (n = 272, age 42 ± 12.54 years, 222 [81.6%] male) more often had microsporidiosis than healthy subjects by modified trichrome stain and PCR (n = 170, age 33.8 ± 6.7 years, 123 [72.3%] male) (16/272 [5.8%] vs 0/170 [0.0%], P < 0.001). Patients with intestinal microsporidiosis were younger (33.9 ± 9 years vs 42.3 ± 12.6 years; P = 0.009), had diarrhoea more often (13/16 [81%] vs 123/256 [48%]; P = 0.020), which was longer in duration (47.5 [25-90] days vs 12 [7-18] days; P < 0.001) and had associated giardiasis (2/16 [12.5%] vs 2/256 [0.8%]; P = 0.018). Younger age, presence of diarrhoea and associated giardiasis were significant on multivariate analysis. Enterocytozoon bieneusi were isolated in 15/16 (93%) patients with intestinal microsporidiosis. Conclusions: Intestinal microsporidiosis occurs frequently in patients with RT on immunosuppressive treatment, particularly among younger patients with longer diarrhoea duration and associated giardiasis. E. bieneusi is the major species identified among these patients. Background/Aims: Enteric parasite Cryptosporidium causes voluminous diarrhoea, prolonged symptoms and recurrences in immunocompromised patients, while in immunocompetent patients infection resolves in few weeks. Variation in the host genetic factors, leading to impaired immune mechanisms might cause this differential manifestation. Toll-like receptors (TLR) 2/4 specifically recognize lipopolysaccharide motifs on surfaces of microorganisms. Polymorphism in TLR genes has resulted in abnormal host-pathogen interaction due to variation in TLR proteins. Thus, we aimed to study the relationship between TLR 2/4 polymorphism and cryptosporidiosis. Methods: Two hundred and twenty-two immunocompromised (154 renal transplant recipients and 68 HIV positive patients) and 200 healthy subjects (HS) were evaluated for TLR2 196_174del, TLR4 Asp299Gly and Thr399Ile polymorphisms by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). Three stool samples were collected from each patient for microscopy and EDTA-blood samples were taken for TLR PCR-RFLP. Results: Sixty-two out of 222 immunocompromised patients and none of the HS were positive for Cryptosporidium. Logistic regression analysis was performed between genotype and allele distributions of the Cryptosporidium positive group and the 2 control groups, ig, immunocompromised patients without cryptosporidiosis and HS. It revealed no significant association between TLR2 196_174 del, TLR4_299, and TLR_399 heterozygote and homozygote states and occurrence of cryptosporidiosis in our population. Conclusions: This is the first study to investigate the role of TLR gene polymorphisms for susceptibility to Cryptosporidium. This study also confirmed the low frequency of the three polymorphisms in our population, as observed in other studies. Although, no significant association was found, studies comprising of very large population from independent geographical/ ethnic groups might decipher the involvement of these polymorphisms with the infection. S62 ANMA 2015 India Selected Poster Presentation No. 119 No. 120 Translation and Validation of Enhanced Asian Rome 3 Questionnaires in Bengali Language for Diagnosis of Functional Gastrointestinal Disorders Virulence Factors of Helicobactor pylori Among Patients With Functional Dyspepsia and Peptic Ulcer in the Community: A Study by cagA and vacA Genotyping 1 2 Mohammed Masudur Rahman, Uday C Ghoshal, AHM Rowshon, 1 1 4 Faruque Ahmed, Md.

Golam Kibria, Faruque Ahmed, AHM Rowshon,5 Nigar Sultana,1 Abdullah yousuf,5 and Mahmud Hasan6 1 Background/Aims: Since functional gastrointestinal disorders (FGIDs) are diagnosed by symptom-based criteria and socio-cultural and linguistic factors may influence symptom reporting, cultural adaptation of the questionnaire and its translation and validation is important. Hence, we translated and validated the Enhanced Asian Rome 3 questionnaire (EAR3Q) in Bengali. Methods: From May 2011 to February 2012, the EAR3Q was translated in Bengali as per guideline from the Rome Foundation. The translated questionnaire was validated on a prospective samples of Bengali speaking healthy subjects (HS, n = 10), and patients with functional dyspepsia (FD, n = 20), irritable bowel syndrome (IBS, n = 20), and functional constipation (FC, n = 10) diagnosed by clinicians using Rome 3 criteria. The subjects were asked to fill-up the questionnaire again after two weeks, to check for its reliability. Results: During translation, the original and backward translated English versions of the questionnaire demonstrated high concordance. The median age of the patients with FD, IBS, FC, and HS were 30 (range 18-42), 30 (18-65), 35 (18-70), and 27 (18-42) years, respectively. Agreement (kappa values) between clinical and translated questionnaire-based diagnosis at initial and at 2 weeks follow-up visits for FD, IBS, FC, and HS were 1.0, 1.0, 0.9, and 1.0, and 1.0, 1.0, 1.0, and 1.0, respectively. Bengali questionnaire detected considerable overlap symptoms of FD among patients with IBS, IBS among patients with FD and FD among patients with FC, which were not detected by the clinicians. Conclusions: We successfully translated and validated the EAR3Q in Bengali. We believe that this translated questionnaire will be useful for clinical evaluation and research among Bengali speaking population. 2 Dhaka Medical College, Dhaka, Bangladesh; Sanjay Gandhi Postgraduate 3 Institute of Medical Sciences, Lucknow, India; ICDDR, B Dhaka, 4 5 Bangladesh; Apollo Hospitals, Dhaka, Bangladesh; Shaheed Suhrawardy 6 Medical College, Dhaka, Bangladesh; and BMRC, Dhaka, Bangladesh Background/Aims: Though the role of Helicobactor pylori in peptic ulcer (PU) is well-established, its role in functional dyspepsia (FD) is controversial. Hence, we undertook a study in a Bangladeshi rural community to evaluate the virulence-associated genes of H. pylori (cagA, vacA, and specifically the vacA allelic variants) among patients with FD as compared to PU with a hypothesis that H. pylori may be as virulent among these patients as compared to those with PU. Methods: H. pylori was identified and genotyped using multiplex polymerase chain reaction on antral biopsies among dyspeptic subjects (diagnosed using Rome III criteria) while door-to-door survey in a rural community in Bangladesh. Results: Of 268 dyspeptic subjects, 190 (71%) had FD and 78 (29%) had PU (active PU and ulcer in remission). H. pylori was detected as commonly among patients with FD as those with PU (170/190 [89.5%] vs 74/78 [95%]; P = 0.238). H. pylori infected patients with PU had higher frequency of cagA positivity than those with FD (52/74 [70.36 %] vs 74/170 [43.5%] P = 0.000). Among the patients with FD and PU, The frequency of vacA genotypes s1m1, s1m2, s2m1, and s2m2 among patients with FD and PU was 66/170 (38.8%) vs 48/74 (64.9%) (P = 0.000); 48/170 (28.2%) vs 15/74 (20.3%) (P = 0.207); 6/170 (3.5%) vs 1/74 (1.4%) (P = 0.678) and 7/170 (4.1%) vs 1/74 (1.4%) (P = 0.441), respectively. Conclusions: These data suggest that patients with PU in the community had more virulent H. pylori compared to those with FD. These data contradict some of the earlier studies that suggested that in hyper-endemic areas such as India and Bangladesh frequency of virulent strains of H. pylori is comparable among patients with FD and PU in hospital-based studies. S63 ANMA 2015 India Selected Poster Presentation No. 121 No. 122 Characteristics of Neural Immunoreactive Staining of Serum Anti-enteric Neuronal Antibodies in Patients With Irritable Bowel Syndrome and Its Clinical Significance Mitochondrial Neurogastrointestinal Encephalopathy: An Unusual Cause of Intestinal Obstruction 1 1 2 Arun Karyampudi, Abhai Verma, Kausik Mandal, Priyanka 2 2 2 1 Srivastava, Dhanya Lakshmi, Shubha R Phadke, Vivek A Saraswat, 1 and Uday C Ghoshal Lingling Chen, Guijun Fei, Ping Wen, Chengdang Wang, Haiwei Xin, and Xiucai Fang 1 2 Departments of Gastroenterology and Medical Genetics, Sanjay Gandhi Post-Graduate Institute of Medical Sciences, Lucknow, India Department of Gastroenterology, Peking Union Medical College Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College, Beijing, China Background/Aims: Mitochondrial neurogastrointestinal encephalopathy (MNGIE), an autosomal recessive disorder, is characterized by gastrointestinal dysmotility, cachexia, extra-ocular muscle weakness, peripheral neuropathy, leucoencephalopathy, and acquired mitochondrial DNA abnormalities in various tissues. It is caused by mutation in thymidine phosphorylase (TYMP) gene causing depletion of the enzyme activity. Methods: A 16-year-old emaciated male presented with recurrent vomiting and loose stools since 9 years of age. His illness remained undiagnosed for seven years in spite of multiple consultations and investigations to find out a mechanical cause for intestinal obstruction that failed. He received anti-tubercular drugs (ATD) with a misdiagnosis of intestinal tuberculosis and homoeopathic treatment. His body mass 2 index was 7.1 kg/m and had visible intestinal peristalsis. He had ptosis, external ophthalmoplegia and diminished deep tendon reflexes. Stomach and duodenum were hugely dilated with features of superior mesenteric artery syndrome on CT scan. Results: Esophageal manometry and radionuclide gastric emptying showed abnormal motility of esophagus and stomach. Cerebral MRI and nerve conduction studies showed diffuse leucoencephalopathy and axonal and demyelinating polyneuropathy. Diagnosis of MNGIE was confirmed by identification of 2 novel mutations in the TYMP gene. Though allogenic stem cell transplantation is the only effective treatment but the literature on this is limited. He received nasojejunal tube feeding, prokinetics, rifaximin for small intestinal bacterial overgrowth, ATD for associated pulmonary tuberculosis, and Co-enzyme Q 10. He improved (BMI 12 at 4-mo). Conclusions: MNGIE is rare and may present with gastroparesis and intestinal pseudo-obstruction. High index of suspicion is required for an early diagnosis. Background/Aims: The aim of the study is to investigate the characteristics of neural immunoreactive straining of serum anti-enteric neuronal antibodies in irritable bowel syndrome (IBS) patients, to analyze the relationship between the antibodies and clinical symptoms. Methods: IBS patients met the Rome III criteria were enrolled, and had been excluded the organic diseases by laboratory examinations and colonoscopy. Indirect immunofluorescence (IIF) was used to detect the sera anti-enteric neuronal antibodies with the substrate of enteric submucosal plexus of guinea pig. The immune reactivity (IR) stains were read and graded by 2 independent investigators in blinded manner. The bowel symptoms and defecation-related symptoms of patients with positive staining and negative staining were compared. Results: A total of 139 IBS patients were enrolled. The positive rate of serum anti-enteric neuronal antibodies in IBS patients was 84.9%, which is significantly higher than in healthy controls (n = 86, 7.0%, P < 0.001). Among 118 IBS sera with positive immune reactivity, 26.3% of them presented as strongly positive staining (+++), 51.7% as positive (++), 22.0% as weakly positive (+). Several IR staining patterns were observed: positive staining only within cytoplasm in 81 sera, purely nucleus staining in 2 cases, purely nuclear membrane staining in 2 cases, both cytoplasm and nuclear membrane staining in 30 cases, and both cytoplasm and nucleus staining in 3 cases. All of 6 positive healthy control sera showed cytoplasm staining only. The anti-enteric neuronal antibodies negative staining group and positive staining group in IBS patients have no significant differences in age, gender and disease duration. IBS patients in positive staining group are more commonly associated with bowel urgency comparing with patients in negative staining group (87.3% vs 57.1%, P = 0.002). Compared with patients with negative and week positive IR, more patients with higher intensity IR have higher intestinal symptoms scores (> 10 scores), frequent abdominal pain in non-defecation period, and severe abdominal pain/discomfort before defecation (58.8% vs 38.1%, P = 0.028; 91.7% vs 60.0%, P = 0.04; 24.7% vs 9.5%, P = 0.043, respectively). Conclusions: In our study, the positive rate of sera anti-enteric neuronal antibodies in IBS patients was higher than in the healthy controls. IBS patients with positive or higher staining intensity of anti-enteric neuronal antibodies presented more severe bowel symptoms than the patients with negative and weakly positive staining,suggesting that the anti-enteric neuronal antibodies might cause or aggravate bowel symptoms by affecting enteric nervous system. Anti-enteric neuronal antibodies may play a role in the pathogenesis of IBS, which have the potentiality to be a biomarker for IBS. S64 ANMA 2015 India Selected Poster Presentation No. 123 No. 124 Effects of Postprandial Coffee Intake on the Rate of Gastric Emptying of Liquid and Solid Meals: A Crossover Study Using 13C Breath Test Prevalence and Self-Recognition of Sonstipation in Japanese Population Fumihiko Toyoshima, Toshihiko Tomita, Akio Tamura, Takahisa Yamasaki, Takashi Kondo, Tomoaki Kono, Katsuyuki Tozawa, Hisatomo Ikehara, Yoshio Ohda, Tadayuki Oshima, Hirokazu Fukui, Jiro Watari and Hiroto Miwa Kenji Kanoshima, Takashi Nonaka, Yumi Inou, Shiori Uchiyama, Mizue Matsuura, Takuma Higurashi, Hiroshi Iida, Tomonori Ida, Hiroki Endo, Masahiko Inamori, Kusakabe, Shin Maeda, and Atsushi Nakajima Hyogo College of Medicine, Nishinomiya, Japan Background/Aims: Constipation is a common symptom. Most patients recognize constipation by one or more symptoms, such as hard stools, infrequent stools (typically fewer than 3 per week), the need for excessive straining, a sense of incomplete bowel evacuation. However, there is no international consensus definition of constipation so far. The aim of study was (1) to assess self-recognition of constipation in Japanese population and (2) to examine the prevalence of constipation using the criteria of Japanese society of internal medicine. Methods: An internet questionnaire survey of 5155 adult members of the general public in Japan who were screened for constipation using the criteria of Japanese society of internal medicine was conducted. The definition of constipation identified it as an inability to evacuate stool completely and spontaneously three or more times per week. Questionnaire including self-recognition of constipation, frequency of defecation, interval, form, management were also obtained. Results: Adult of the general public in Japan who recognize themselves as constipation were found in 28.4%, among them 50.7% think them constipated in 20’s women. However, the prevalence of constipation was found only in 10.1% using the criteria of Japanese society of internal medicine. Interestingly, subjects who regard constipation as disease were seen only in 48.8%. The management of constipation in Japanese population was as follows; intake of liquid (52.2%), reservation of sleeping time (39.7%), and only 7.9% take some medicines (including OTC) for constipation. Conclusions: There is a discrepancy in the prevalence of constipation between by self-recognition and that defined using the criteria of Japanese society of internal medicine. Background/Aims: Coffee is one of the most popular beverages worldwide, however, few studies have examined the effects of coffee on the gastrointestinal system. The aim of this study was to determine whether there was a correlation between coffee intake and gastric emptying of liquid and solid meals using 13C breath test. Methods: Six healthy volunteers participated in this randomized, two-way crossover study. The subjects fasted overnight and were randomly assigned to receive 190 mL black coffee following ingestion of the liquid test meal (200 kcal per 200 mL) labelled with 100 mg 13 C-acetate, or the liquid test meal alone. Under both conditions, gastric emptying was monitored for 4 hours after administration of the 13 test meal by the C breath test performed continually using the BreathID system. Liquid gastric emptying was estimated by the values of T1/2 and Tlag, using Oridion Research Software. Moreover, other 6 healthy volunteers were randomly assigned to receive 190 mL black coffee or 190 mL water following ingestion of the solid test meal 13 (a pancake, 350 kcal) labelled with 100 mg C-octanoic acid after an overnight fast. Under both conditions, breath samples were collected for 150 minutes following the meal ingestion using air bags. Solid gastric emptying was estimated by the values of Tmax. The above parameters between the coffee intake and the control were compared statistically. Results: In the coffee intake after ingestion of the liquid test meal, significant differences compared with the control condition were found in T1/2 (median 105.7 [range 85.7-123.1] minutes vs 121.3 [107.2-134.0.0] minutes; P = 0.023) and Tlag (median 49.5 [21.0-68.5] minutes vs 65.6 [49.8-87.6] minutes; P = 0.046]. Whereas, no significant difference in the Tmax was observed between the coffee intake and the control after ingestion of the solid test meal (median 82.5 (50.0-105.0) minutes vs 60.0 [40-150] minutes; P = 0.528). Conclusions: This study showed that postprandial coffee intake significantly enhances gastric emptying of a liquid meal, not a solid meal. S65 ANMA 2015 India Selected Poster Presentation No. 125 No. 126 The Value of High Resolution Manometry in Patients Presenting With Gastroesophageal Reflux Disease Symptoms With Normal Endoscopy and Negative 24 Hour pH-Impedance Study pH Probe Placement in Children: Arithmetic Calculations Much Inferior to Esophageal High-resolution Manometry Alex Yu Sen Soh, Kewin Tien Ho Siah, Chin O Ho, Ho Khek Yu, and Reuben K Wong Department of Pediatric Gastroenterology, Sanjay Gandhi Postgraduate Institute of Medical Sciences, Lucknow, India Anshu Srivastava, Amrita Mathias, Rohan Malik, Surender K Yachha, and Ujjal Poddar Department of Gastroenterology and Hepatology, National University Hospital, Singapore, Singapore Background/Aims: Precise definition of lower esophageal sphincter (LES) by high-resolution manometry (HRM) helps in correct placement of the pH probe. Various arithmetic calculations are used to predict esophageal length (EL) for pH placement in children. This study determined the validity of these formulae to predict EL in comparison to HRM. Methods: Sixty-three children (40 boys, age 12.5 ± 3.1 years) underwent esophageal HRM by a 22channel water perfusion system (MMS) to determine LES position and EL was calculated using upper border of LES as reference point. The patients height, EL by Strobel’s formula (SF) and by the new formula (NF) proposed by 1 Moreau et al was recorded. Patients with scoliosis, neurological impairment and esophageal surgery were excluded. Formula calculated EL was compared with HRM measured values. Results: The mean EL on HRM was 35.3 ± 3.5 cm and the LES length was 2.4 ± 0.5 cm. The height ranged from 88.0-171.4 cm, with a significant correlation between the child’s height and EL by HRM (r = 0.857, r2 = 0.730; new equation: EL = 0.2 × height + 6.587; P < 0.001). Calculated EL by SF was 41.3 ± 3.8 cm, significantly more than HRM values (difference 5.9 ± 2.0 cm; P < 0.001). Similarly, NF also overestimated the EL in comparison to HRM (38.2 ± 3.3, difference 3.0 ± 0.55 cm; P < 0.001). NF was significantly better than SF in predicting EL. Conclusions: HRM should be the preferred method for pH catheter placement in children. Arithmetic calculations based on height of the child significantly overestimate EL, with SF performing poorer than the NF. Reference 1. Moreau B, Kambites S, Lévesque D. Esophageal length: esophageal manometry remains superior to mathematical equations. J Pediatr Gastroenterol Nutr 2013;57:236-239. Background/Aims: The number of patients presenting with gastroesophageal reflux disease (GERD) related symptoms are increasing in Asia. Currently GERD patients with negative endoscopy are divided to non-erosive reflux disease or functional heartburn according to ROME III criteria after 24-hour pH-Impedance and proton pump inhibitor treatment. We aim to investigate the value of high-resolution manometry (HRM) in GERD patients with normal endoscopic findings and negative 24 hour pH-Impedance test. Methods: Consecutive patients referred to the motility laboratory were invited to participate in the study. Inclusion criteria were patients with GERD related symptoms, normal endoscopic findings and negative dysphagia. Both 24 hour pH-Impedance study and HRM study were carried out. Biophysical, social and GERD Quality of Life data were also collected. Results: We recruited 101 patients (54 males, 47 females) with a mean age of 49.0 (SD 15.4). Nineteen patients had positive 24 hour pH-Impedance test, 26.3% of them had positive HRM findings (4 weak peristalsis and 1 esophagogastric junction outflow obstruction). 43% with negative 24 hour pH-Impedance (35 out of 82 patients) had positive HRM findings. Majority had weak peristalsis (19 patients), however, 6 had esophagogastric junction outflow obstruction, 4 had nutcracker esophagus, 3 had Type II Achalasia, and 2 had absent peristalsis. Presenting symptoms were not able to differentiate between positive and negative findings in both 24 hour pH-Impedance and HRM tests. Conclusions: GERD patients with normal endoscopy and negative 24 hour pH-Impedance may benefit from HRM evaluation. S66 ANMA 2015 India Selected Poster Presentation No. 127 No. 128 Characteristics of Esophageal pH-Impedence Monitoring in Non-erosive Reflux Disease Patients On and Off Protein Pump Inhibitor Therapy Characteristics of Multichannel Impedence With pH Metry in Refractory Gastroesophageal Reflux Disease Patients On and Off Proton Pump Inhibitor Therapy in Indian Population Rakesh Kalapala, Jaya Agarwal, and D Nageshwar Reddy Rakesh Kalapala, Jaya Agarwal, and D Nageshwar Reddy Department of Gastroenterology, Asian Institute of Gastroenterology, Hyderabad, India Department of Gastroenterology, Asian Institute of Gastroenterology, Hyderabad, India Background/Aims: Non-erosive reflux disease (NERD) is the common form of presentation of gastroesophageal reflux disease (GERD). About 50% of patients with typical GERD symptoms have normal endoscopy findings. Both acidic and non-acidic refluxes contribute to symptomatology in these group of patients. We aimed to evaluate the characteristics of impedence-pH monitoring in non-erosive reflux disease (NERD) patients who are on and off PPI therapy. Methods: Forty-eight patients with symptoms of reflux disease and normal endoscopy findings were included in the study. The patients were divided into 2 groups: proton pump inhibitor (PPI) (+) group (on PPI therapy for more than 4 weeks) and PPI (-) group (off PPI therapy for more than 4 weeks). All these patients underwent 24-hour pH with impedance monitoring after informed consent. Twenty-one patients were in PPI (+) group and 27 were in PPI (-) group. The acidic, nonacidic reflux events, proximal and distal extent of the reflux including the median bolus clearance time were recorded. The symptom index (SI) and symptom association probability (SAP) were also noted. Results: Mean age were 42 and 44.7, and M:F ratio were 13:8 and 25:2 in PPI (+) and (-) groups, respectively. There was no significant statistical difference in any of the variables in both groups. Multivariate logistic regression analysis showed odds ratio > 1 in acid supine reflux, non-acidic supine and total reflux, SAP (heart burn), deMeester score, proximal and distal reflux episodes supine, and symptom correlation (heart burn and belch) with 95% confident interval. Conclusions: Twenty-four-hour impedence-pH monitoring in patients with NERD who are on and off PPI therapy does not show any significant difference in assessment of relationship between symptoms and reflux episodes and also other variables like reflux episode activity and bolus exposure. However, the odds ratio in the above mentioned variables can be proposed as the risk factors in patients with NERD but need a large population study to propose the same. Background/Aims: Gastroesophageal reflux disease (GERD) is a common condition affecting a large population. Traditionally GERD has been associated with acidic refluxes. The regular 24-hour pH metry can detect acidic reflux only. The 24-hour multichannel intraluminal impedence with pH metry (MII-pH) enables monitoring of both acidic and non-acidic reflux episodes including the extent of each episode into the esophagus. The variations of these reflux episodes in patients with and without proton pump inhibitor (PPI) therapy have not been evaluated. To assess the reflux patterns of GERD patients who are on and off PPI therapy with combined MII-pH. Methods: One hundred twenty patients (75 M , 45 F) with symptoms of reflux disease and erosive esophagitis on endoscopy were included. Subjects on PPI therapy for more than 4 weeks were included in the PPI (+) group. The subjects without any PPI therapy for at least 4 weeks prior to the study were included in the PPI (−) group. These underwent MII-pH after informed consent. Twenty-two patients were in PPI (+) group and and 28 were in PPI (−) group. The acidic, nonacidic reflux events, proximal and distal extent of the reflux including the median bolus clearance time were recorded. The Symptom index (SI) and Symptom association probability (SAP) were also noted. Results: Mean age and M:F ratio of both groups was similar. Acid reflux events (upright and supine), the composite deMeester score and the proximal extent of the refluxes was significantly higher in the PPI (−) group (P < 0.001).The majority of refluxes in the subjects on PPI (+) group were supine and non-acidic type. The SI, SAP, and median bolus clearance did not demonstrate statistical significance between the 2 groups. Logistic regression analysis showed odds ratio > 1 in non-acidic supine reflux, SAP (belch), SI (heartburn), and distal extent reflux events with 95% confident interval for subjects in the PPI (−) group. Conclusions: The study demonstrates that persistent symptoms in subjects of the PPI (+) group of GERD are possibly related to non-acidic refluxes predominantly in the supine position. This increased frequency of supine non-acid reflux events reflects an increased exposure of distal esophagus to gastric and duodenal secretions. These non-acid refluxes are not detectable with traditional esophageal pH metry alone and hence MII-pH metry may be mandatory for patients with refractory GERD symptoms. S67 ANMA 2015 India Selected Poster Presentation No. 129 No. 131 Orocecal Transit Time in Gastrointestinal Diseases in Indian Patients Small Intestinal Bacterial Overgrowth and Orocecal Transit Time in Cirrhosis and Non-cirrhotic Portal Hypertension Satya V Rana S K Sinha, S V Rana, D K Bhasin, U Dutta, HS Dhaliwal, K Singh, and R Kochhar Department of Gastroenterology, Post Graduate Institute of Medical Education and Research, Chandigarh, India Department of Gastroenterology, Post Graduate Institute of Medical Education and Research, Chandigarh, India Background/Aims: Orocecal transit time (OCTT) is one of main determinants of gastrointestinal motility. While marked-isotopes scintigraphy is gold standard in its determination in clinical frame, breath tests are cheap, well-tolerated and non-invasive alternatives. Gastroenterologists have shown great interest in simple and non-invasive methods of assessing gut transit. Secondly, rate of passage of barium during small bowel radiology is unreliable and lacks correlation with symptoms. Therefore, Lactulose hydrogen breath test was used to measure orocecal transit time in different gastrointestinal diseases such as irritable bowel syndrome (IBS), inflammatory bowel disease (IBD), gall stones, etc. Methods: For this method, adult patients of IBS, IBD, gall stones, and 100 apparently healthy age and sex matched subjects were instructed to consume low fiber diet 3 days before test. Fasting end expiratory breath was taken .Then 15 mL lactulose syrup containing 10 g lactulose was given to patients and controls to drink and end expiratory breath was taken after every 10 minutes up to 4 hours. Subjects were instructed not to sleep, exert and smoke during test. Time taken for rise > 10 ppm in hydrogen concentration over fasting value was considered as orocecal transit time. Results: It was observed that the age range of patients and controls was 18 to 65 years. Results of orocecal transit time in different gastrointestinal diseases and controls will be presented. Mean of orocecal transit time of controls was 90.5 minutes while of IBS patients 98.7 minutes, of IBD patients 145.9 minutes and of gall stone patients 128.6 minutes. Conclusions: It was observed that the orocecal transit was significantly delayed in IBD and gall stone patients as compared to controls but no significant change in patients with IBS. Background/Aims: Motility disturbances in achalasia cardia are not restricted to esophagus only. We have reported delayed liquid gastric emptying in achalasia cardia earlier. The aim of study was to measure the small intestinal transit time in patients with achalasia cardia Methods: This prospective study included patients with achalasia cardia diagnosed on the basis of barium swallow findings and esophageal manometry. Informed consent was obtained from each patient. Small bowel transit time was measured by lactulose hydrogen breath test. The test was performed in each patient after overnight fast by instilling 10 g of lactulose just beyond the pylorus during index esophagogastroduodenoscopy examination. Breath hydrogen was measured at base line and then every 15 minutes for 180 minutes or more. Time taken for rise in breath hydrogen by more than 5 ppm was taken as small intestinal transit time. Patients with a history of intake of drugs like antibiotics, prokinetics, lactulose, histamine H2 receptor antagonist, and proton pump inhibitor in preceding 4 weeks were excluded. Results: The study included 27 patients (17 males, 10 females). Mean age was 37.9 ± 13.5 years. The mean small intestinal transit time was 81.7 ± 41.7 minutes. However, 7 out of 27 patients (25.9%) had small intestinal transit time of 105 minutes or more (which is the upper limit for the orocecal transit time in our laboratory). Conclusions: Abnormality of small intestinal transit is common in patients with achalasia cardia.

Benzalkonium chloride (BAC), a kind of cationic disincrustant, can damage enteric nerve tissue at certain concentrations. Activin A, also called neuronal survival factor, can provide neuroprotective and anti-inflammatory effects, and is helpful for repair of stromal cells. But few reports describe the neuroprotective and promoting effects of activin A on the survival of enteric neurons, intestitial cells of Cajal (ICC) and smooth muscle cells (SMCs). The aim of study was explore the effect of activin A on duodenl myenteric plexus, ICC and slow waves of SMCs. Methods: All Sprague-Dawley male rats were divided randomly into 3 groups: control, denervated, and Activin A-treated group. The duodenum of denervated group rats was wrapped around by cotton wool soaked in 0.9% saline containing 0.5% BAC for 30 minutes. Then the peritoneum and treated area were flushed with 0.9% saline several times .The activin A-treated group were injected with activin A (0.005 mg/mL) 10 mL/kg/day for 2 weeks via tail vain. After 2 weeks, neurons, and ICCs in duodenal myenteric plexus were counted by immunohistochemistry staining. Changes of protein gene product 9.5 (PGP9.5) in duodenum were determined by western blotting. The slow waves of SMCs were recorded by intracellular recording. Results: The number of neurons (PGP9.5), c-kit, and the quantity of PGP9.5 protein of activin A-treated group increased significantly compared with denervated group (all P < 0.01), but they were decreased significantly compared with the control group (all P < 0.01). The amplitude of slow waves in duodenal smooth muscle in the activin A-treated group was significantly higher than that in the denervated group (13.80 ± 5.39 vs 6.90 ± 2.12, P < 0.05), but the frequency was not significantly changed (26.50 ± 1.28 vs 26.60 ± 1.69, P > 0.05). The frequency and amplitude of slow waves in duodenal smooth muscle in the activin A-treated group were significantly lower than those in the control group (20.50 ± 3.72 vs 6.90 ± 2.12, P < 0.05; 26.50 ± 1.28 vs 35.00 ± 1.20, P < 0.05). Conclutions: The duodenum was denervated significantly after application of BAC for 2 weeks. The ICCs and slow waves of SMCs also changed obviously. Activin A can protect enteric neurons and promote them survive and is also helpful for repairing ICCs and improving the slow waves of SMCs. This provided evidence for the treatment of gastrointestinal disorders related to enteric neurons in the future. Background/Aimds: Irritable bowel syndrome (IBS) is a common functional gastrointestinal disorder characterized by abdominal pain and alterations in bowel habits. IBS symptoms would not only impair their quality of life, but also bring substantial economic burden to the society. Visceral hypersensitivity (VH) is commonly observed in patients with IBS and has been suggested to play a pathogenic role in development of IBS symptoms. Current treatment of IBS is still unsatisfactory and probiotics may serve as a promising option for the IBS treatment. The aim of study was identify the potential anti-nociceptic effect of Lactobacillus plantarum PS128 in a rat model with VH, mimicking IBS symptoms. Methods: Lactobacillus plantarum PS128 (109 colony-forming unit in 0.2 mL saline/rat/day) or placebo (0.2 mL saline/rat/day) were fed to male Sprague-Dawley rats for 14 days. 5-Hydroxytryptophan (5-HTP) was injected subcutaneously into awake rats to induce VH at day 0 and day14. Colorectal distension (CRD) with simultaneous electromyography recording was done 30 minutes before and 30 minutes after 5-HTP injection. Spinal substance P level was measured at 14 days after finishing CRD test. Results: The visceromotor reflex (VMR) was statistically significantly higher after 5-HTP administration (P < 0.05). Oral administration of PS128 for 14 days successfully reversed the 5-HTP-induced VH. The VMR differences between baseline and after 5-HTP administration was statistically higher in PS128 group compared with placebo group (P < 0.05). Rats fed with placebo were found to have a significantly increased spinal level of substance P, an important excitatory neurotransmitter, after 5-HTP injection followed by CRD. Administration of PS128 could reverse spinal substance P level after 5-HTP-sensitization and CRD. Conclusions: PS128 would ameliorate the 5-HTP-induced VH, which may go through the substance P-containing neural pathway in spinal cord.

Methods: CVH was induced by colorectal injection of acetic acid (AA) in 10-day-old rats, colon-specific DRG neurons were retrogradely labeled by injection of DiI (1,1'-Dioctadecyl-3,3,3',3'Tetramethylindocarbocyanine Perchlorate) into the colon wall. Expression of TRPV1 receptors was determined by immunofluorescence staining and electrophysiological characteristics were measured using whole patch clamp techniques. Results: Compared to the controls, the expression of TRPV1 receptors in the colon-specific DRG neurons was significantly higher (P < 0.01) and the frequency of Aps (P < 0.01). Conclusions: These data suggest that there is a close relationship between visceral hypersensitivity and increased expression of TRPV1 receptors and excitability in colon-specific DRG neurons which is conducive to provide an effective target to treat visceral hypersensitivity. S70 Background/Aims: Pneumatic dilation (PD) is an effective treatment of achalasia; 1-30% patients undergoing PD have esophageal perforation (EP), which may require surgery. Data on frequency, profile and outcome of EP are not widely reported. Methods: Records of patients undergoing PD for achalasia during a 16.5 year period (April 1998 to September 2014) were retrospectively reviewed. Results: Eleven (median age 43 years, range 27-74, male 5 [45%]) of 455 (2.4%) PD sessions, on 414 patients (2.6%), had EP. Seven and 4 patients had type 1 and 2 achalasia, respectively. Median resting lower esophageal sphincter (LES) pressures was 43 mmHg (range 16-60). The size pneumatic balloon used for PD were 30 mm (n = 6), 35 mm (n = 4), and 40 mm (n = 1). Ten out of 11 EP occurred during the first and only 1 during second PD. Chest radiograph done in 6 patients revealed pneumomediastinum in 3 (50%) but computerized tomographic scan of chest done in 5 revealed pneumomediastinum in all. Contrast radiograph using gastrograffin revealed perforation in 7/9 (78%) patients in whom it was performed. Seven patients needed surgical treatment (all had contrast leak), 1 was managed successfully with self-expandable covered metal stent and 3 (1 had contrast leak) improved with conservative treatment. At surgery, median length of the perforation was 3 cm (range 2-5); sites of perforation were: the left lateral wall in 4, left antero-lateral wall in 2, and posterior wall in 1. Conclusions: EP perforation occurs in 2.4% PD, most often in the first session. Effective management of this dreaded complication is usually associated with good outcome. ANMA 2015 India Selected Poster Presentation No. 136 No. 137 Vitamin-D Deficiency is Associated With Gallbladder Stasis Among Pregnant Women Vitamin D Supplementation Improves Gallbladder Ejection Fraction in Patients With Gallstones Rimpi Singla, Usha Dutta, Neelam Aggarwal, Sanjay Kumar Bhadada, Rakesh Kochhar, Lakhbir K. Dhaliwal Gayathri Petluri, Usha Dutta, Anish Bhattacharya, Sanjay Bhadada, and Kartar Singh Departments of Gastroenterology, Obstetrics and Gynecology, and Endocrinology, Postgraduate Institute of Medical Education and Research, Chandigarh, India Departments of Gastroenterology, Obstetrics and Gynecology, and Endocrinology, Postgraduate Institute of Medical Education and Research, Chandigarh, India Background/Aims: Pregnant women are at an increased risk for gallbladder (GB) stasis, an important risk factor for gallstones (GS). In non-pregnant women, we found that Vitamin-D deficiency (VDD) was associated with GB stasis, which improves on supplementation. Revalence of VDD and its relationship to GB stasis among pregnant women is not known. Methods: Prospective study conducted at a tertiary care center. Consecutive healthy pregnant women (12-16 weeks gestation) were enrolled. Serum 25 (OH) Vitamin-D was estimated and levels < 20 ng/mL was considered as VDD. Risk factors and clinical features of VDD were assessed. Gallbladder ejection fraction (GBEF) was assessed by ultrasound after a standard fatty meal and < 40% was defined as stasis. Statistical analysis was performed to assess relationship of GB stasis and vitamin-D levels and identify factors associated with VDD. Results: Median serum vitamin-D in 304 women studied was 7.9 ng/mL (interquartile range [IQR] 5.7, 12). VDD afflicted 92% of them. Women with VDD, more often had GB stasis than those with normal Vitamin-D (20% [56/280] vs 0% [0/24]; P = 0.015). Women with VDD, had lower GBEF compared to those with normal Vitamin-D (53.7 ± 17% vs 59 ± 10%; P = 0.026). GBEF showed a positive correlation with vitamin-D levels (r = 0.117; P = 0.042). Risk factors for low vitamin-D levels were urban residence (P = 0.001); lower sun-exposure time (P = 0.005); limited skin exposure (P < 0.001); higher BMI (P = 0.050) and higher socioeconomic status (P = 0.020). Vitamin-D levels was associated with low serum calcium ( = 0.457; P < 0.001). Conclusions: Vitamin D deficiency is highly prevalent among pregnant Indian women. It is associated with GB stasis and lower GBEF. The risk factors for VDD were reduced sun exposure and urban lifestyle. Background/Aims: Vitamin D deficiency (VDD) is associated with poor skeletal muscle function, which improves on Vitamin D supplementation (VDS). Effect of VDD and VDS on gallbladder muscle function is not known. To study the relationship of VDD and gallbladder ejection fraction (GBEF) and determine the effect of VDS on GBEF in patients with gallstones (GS). Methods: Prospective study at a tertiary center in North-India. Patients with symptomatic GS (n = 91) were evaluated for their demographic and clinical profile. 25-OH Vitamin-D levels was assessed using chemiluminiscence assay and categorized as deficient (< 20 ng/mL), insufficient (20-30 ng/mL), and sufficient (> 30 ng/mL). GBEF was estimated using cholescintigraphy and classified as non-functional (0%), static (< 40%), and normal GBEF (≥ 40%). GBEF was reassessed in those with functioning GB’s 2 weeks after a single dose of intramuscular Vitamin-D (600 000 IU). Results: Patients with GS (mean age of 48 ± 13 years, 78% F, 86% multiple GS). The mean Vitamin-D levels were 14 ± 7.5 ng/mL Of them, 75 (82.4%) were deficient, 12 (13.2%) insufficient and only 4 (4.4%) had sufficient Vitamin-D levels. Among the 91 patients, GB was non-functional in 13 (14%), static in 15 (16%), and normal in 63 (70%). VDS resulted in resolution of GB stasis in all (100%) of those with stasis (n = 15); with a overall median increase of 17% (interquartile range [IQR] 9.6, 44.4) in GBEF. GBEF increased from 52 ± 16.3% at baseline to 62.7 ± 13.8% after VDS (P = 0.001). Conclusions: Most patients (95%) with GS had Vitamin-D deficiency or insufficiency. Vitamin-D supplementation resulted in significant improvement in GBEF and resulted in resolution of GB stasis in all those with stasis. S71 ANMA 2015 India Selected Poster Presentation No. 138 No. 139 Chicago Classification Parameters for Upright and Supine Position in Gastroesophageal Disease: A Preliminary Report Relation Between Transition Zone and Distal Breaks in Symptomatic Gastroesophageal Reflux Disease and Dysphagia: A Preliminary Report Srinivas M, Vijaya Srinivasan, and Jayanthi V Srinivas M and Jayanthi V Department of Gastroenterology, Global Health City, Chennai, India Department of Gastroenterology, Global Health City, Chennai, China Background/Aims: We observed that there were some differences in interpretation by Chicago classification (CC) in high-resolution esophageal manometry (HREM) done in upright and supine postures among patients with dysphagia and gastroesophageal reflux disease (GERD). We therefore aimed to evaluate the differences in CC parameters for liquid swallows (atleast 5 × 5 mL water) in both positions for patients with GERD retrospectively. Methods: Swallows of 21 patients (excluding achalasia on HREM) with GERD tested in upright and supine position (16-channel water perfused catheter) were analysed for peristaltic breaks (S1and S2 + S3), distal latency (DL), contractile front velocity, integrated relaxation pressure (IRP), and distal contractile integral (DCI). Comparison was made between values for each parameter by test posture. Statistical analyses: Wilcoxon signed rank test; P < 0.05 significant. Results: Three hundred and eighty swallows were analysed (divided equally between both postures) (Table). Overall, most parameters had mean values, irrespective of posture, within the normal CC range. The IRP (8.8 ± 4.5 vs 11.68 ± 9.47; P < 0.03) and DCI (1071.9 ± 982.05 vs 1325.02 ± 1026; P < 0.01) were significantly lower in upright compared to supine values. All the other parameters were similar in both postures. The large standard deviation for DCI was probably due to small sample size. Conclusions: Most parameters in our study were normal by CC values irrespective of posture suggesting the need to standardise normal values in the Indian context. Despite this, lower IRP and DCI among the upright refluxers suggests greater retrograde propulsion in them. Background/Aims: Peristaltic breaks in high-resolution esophageal manometry (HREM) occur in both proximal and distal segments. These may exaggerate the transition zone (TZ) contributing to gastroesophageal reflux disease (GERD) and dysphagia. Study the relationship between segment breaks in GERD and dysphagia by test posture. Methods: Excluding achalasia and post-fundoplication, 112 adult HREM (minimum 5 × 5 mL water swallows, 16-channel water perfused catheter) evaluations for dysphagia and GERD in supine/upright postures were analysed retrospectively. The TZ and distal break (DB) lengths were classified as no (< 2 cm), small (2-5), and large (> 5). The TZ break was correlated with DB by indication and posture using Mann Whitney U test to compare absence and presence of DB in various TZ categories between postures. Results: In GERD, about 50% had TZ breaks irrespective of posture with DB in 36% of them. Even in absence of TZ breaks, 7/42 (16.6%) had DB, especially in upright posture (P < 0.01). In dysphagia, unlike GERD, upright posture was associated with more TZ breaks than supine (48% vs 23%) and DB occurred only in “presence” of small TZ breaks (4/9 vs 0/2 supine, P = 0.050). DB did not occur in “absence” of TZ breaks in either posture. Conclusions: TZ breaks occurred in both GERD and dysphagia (Table). More breaks occurred in the latter in upright posture. Both TZ breaks and DB were common in upright position for both indications, suggesting that upright HREM may be better for assessing dysphagia and GERD. Table.
