Abstract
BACKGROUND & AIMS High-dose proton pump inhibitor (PPI) therapy has been recommended to prevent rebleeding of high-risk peptic ulcer (PU) after hemostasis. Vonoprazan has been proven to be noninferior to PPIs in various acid-related diseases. This study aimed to compare the efficacy of vonoprazan vs PPI for preventing high-risk PU rebleeding after hemostasis. METHODS A multicenter, randomized, noninferiority study was conducted in 6 centers. Pre-endoscopic and endoscopic therapy were performed according to standard protocol. After successful hemostasis, patients with high-risk PU bleeding (Forrest class Ia/Ib, IIa/IIb) were randomized into 1:1 to receive vonoprazan (20 mg twice a day for 3 days, then 20 mg once a day for 28 days) or high-dose PPI (pantoprazole intravenous infusion 8 mg/h for 3 days, then omeprazole 20 mg twice a day for 28 days). The primary outcome was a 30-day rebleeding rate. Secondary outcomes included 3- and 7-day rebleeding rate, all-cause and bleeding-related mortality, rate of rescue therapy, blood transfusion, length of hospital stay, and safety. RESULTS Of 194 patients, baseline characteristics, severity of bleeding, and stage of ulcers were comparable between the 2 groups. The 30-day rebleeding rates in vonoprazan and PPI groups were 7.1% (7 of 98) and 10.4% (10 of 96), respectively; noninferiority (within 10% margin) of vonoprazan to PPI was confirmed (%risk difference, -3.3; 95% confidence interval, -11.2 to 4.7; P < .001). The 3-day and 7-day rebleeding rates in the vonoprazan group remained noninferior to PPI (P < .001 by Farrington and Manning test). All secondary outcomes were also comparable between the 2 groups. CONCLUSION In patients with high-risk PU bleeding, the efficacy of vonoprazan in preventing 30-day rebleeding was noninferior to intravenous PPI. (ClinicalTrials.gov, Number: NCT05005910).

Abstract
BACKGROUND Globus is a persistent or intermittent nonpainful sensation of a lump or foreign body, which markedly affect patient's quality of life. Treatment options for globus are limited and unsatisfying. This study aims to compare the effects of cognitive-behavioral-theory-based psychoeducation (CBT), neuromodulators (NMD), and proton pump inhibitor (PPI) on treatment outcomes in patients with globus. METHODS Eligible patients were randomly received CBT, 0.5 mg flupenthixol and 10 mg melitracen; NMD, or omeprazole 20 mg; PPI, for 4 weeks. The primary endpoint was the reduction in symptom scores; Glasgow Edinburgh Throat Scale (GETS). The secondary endpoints included treatment efficacy on Reflux Symptom Index (RSI), Hospital Anxiety Depression Scale (HADS), and quality of life (QoL) based on a 36-item short-form health survey (SF-36). Treatment compliance and adverse effects were recorded. KEY RESULTS Forty patients were completed study. Baseline characteristics between the groups were comparable. By the end of treatment, both CBT and NMD provided greater reduction in GETS than PPI (CBT vs PPI; 6.46 ± 8.56 vs 0.21 ± 5.42; p = 0.031, NMD vs PPI; 6.92 ± 9.85 vs 0.21 ± 5.42; p = 0.036). The improvement of RSI, HADS, and SF-36 among the groups was similar. Neuromodulators caused more adverse events. CONCLUSIONS & INFERENCES Both CBT and NMD provided equally effective treatment and better than PPI in patients with globus determined by the reduction in GETS. The improvement in RSI, HADS, and QoL of the three groups was not different. Given less of adverse effect than NMD, CBT should be considered as a substantial treatment.

Abstract
In potential small bowel bleeding, video capsule endoscopy (VCE) is excellent to detect mucosal lesions, while mural-based lesions are better detected by computed tomography enterography (CTE). A predictive tool to identify mural-based lesions should guide selecting investigations. In this retrospective study, we developed and validated the "MURAL" model based on logistic regression to predicts bleeding from mural-based lesions. Cost-effectiveness analysis comparing diagnostic strategy among VCE, CTE, and MURAL model was performed. Of 296 patients, 196 and 100 patients were randomly included in the derivative and validation cohorts, respectively. The MURAL model comprises 5 parameters: age, presence of atherosclerosis, chronic kidney disease, antiplatelet use, and serum albumin level. The area under the receiver operating characteristic curve was 0.778 and 0.821 for the derivative and validation cohorts, respectively. At a cutoff value of 24.2%, the model identified mural-based lesions with 70% sensitivity and 83% specificity in the validation cohort. Cost-effectiveness analysis revealed that application of the MURAL model demonstrated a comparable missed lesion rate but had a lower missed tumor rate, and lower cost compared to VCE strategy. The model for predicting mural-based lesions provide some guidance in investigative decision-making, which may improve diagnostic efficiency and reduce costs.

Abstract
Gastroesophageal reflux disease (GERD) is one of the most prevalent and bothersome functional gastrointestinal disorders worldwide, including in Thailand. After a decade of the first Thailand GERD guideline, physician and gastroenterologist encountered substantially increase of patients with GERD. Many of them are complicated case and refractory to standard treatment. Concurrently, the evolution of clinical characteristics as well as the progression of investigations and treatment have developed and changed tremendously. As a member of Association of Southeast Asian Nations, which are developing countries, we considered that the counterbalance between advancement and sufficient economy is essential in taking care of patients with GERD. We gather physicians from university hospitals, as well as internist and general practitioners who served in rural area, to make a consensus in this updated version of GERD guideline focusing in medical management of GERD. This clinical practice guideline was constructed adhering with standard procedure. We categorized the guideline in to four parts including definition, investigation, treatment, and long-term follow up. We anticipate that this guideline would improve physicians' proficiency and help direct readers to choose investigations and treatments in patients with GERD wisely. Moreover, we wish that this guideline would be applicable in countries with limited resources as well.

Abstract
OBJECTIVE Age and alarm features are commonly used as indicators for endoscopy in dyspeptic patients; however, the age cut-off and the predictive value of these parameters for identifying upper gastrointestinal (UGI) malignancies are uncertain. DESIGN Cross-sectional study. SETTING Data were extracted from the Gastrointestinal Endoscopy Centre of Siriraj Hospital, Thailand, during 2005-2011. PARTICIPANTS Consecutive patients underwent a first-time upper endoscopy for dyspepsia. Patients with previous surgery, suspected UGI malignancy by imaging, or indefinite biopsy results on prior examination were excluded. MAIN OUTCOME MEASURES Alarm features included dysphagia, unintentional weight loss, GI bleeding/anaemia, and persistent vomiting. The diagnostic performance of each alarm feature and different age cut-off values were evaluated. RESULTS A total of 4664 patients (mean age: 52.0±14.4 years, 66% female) were included. Alarm symptoms were presented in 21.6%. The prevalence of active Helicobacter pylori infection was 26.3%. Fifty-eight (1.2%) patients had UGI malignancy. The prevalence of malignancy significantly increased with increasing age (0.6% in patients aged <50 years, and 1.8% in patients aged >60 years (p<0.001)). Cancer was found in two patients aged <50 years who did not have alarm features. Patients with alarm features had a higher prevalence of malignancy (OR 22.3, 95% CI 10.5 to 47.4; p<0.001) than those without. The pooled sensitivity, specificity, positive predictive value and negative predictive value of alarm features for UGI malignancy were 87.0%, 79.1%, 4.7% and 99.8%, respectively. Among all age groups, persistent vomiting had a positive likelihood ratio (PLR) >10, while dysphagia and GI bleeding/anaemia had a PLR >10 in patients <50 years old. CONCLUSION Despite the overall limited value of age and alarm features, persistent vomiting, dysphagia, and GI bleeding/anaemia are strong predictors for malignancy in patients aged <50 years. Without these symptoms, cancer prevalence is negligible; thus, they are worthy guidance for endoscopic evaluation in this age group.

Abstract
This paper reports the proceedings from the first consensus meeting on the management of mild-to-moderate gastroesophageal reflux disease (GERD) in the Southeast Asian (SEA) region. Seventeen statements were drawn up by a steering committee that focused on epidemiology, mechanism of action, diagnostic investigations, and treatment. Voting on the recommendations used the Delphi method with two rounds of voting among the 10 panel members. The consensus panel agreed that GERD is mostly a mild disease in the SEA region with predominantly non-erosive reflux disease (NERD). Complicated GERD and Barrett's esophagus are infrequently seen. The panel recommended endoscopy in patients with alarm or refractory symptoms but cautioned that the incidence of gastric cancer is higher in SEA. pH and impedance measurements were not recommended for routine assessment. The acid pocket is recognized as an important pathogenic factor in GERD. Lifestyle measures such as weight reduction, avoidance of smoking, reduction of alcohol intake, and elevation of the head of the bed were recommended but strict avoidance of specific foods or drinks was not. Alginates was recommended as the first-line treatment for patients with mild-to-moderate GERD while recognizing that proton-pump inhibitors (PPIs) remained the mainstay of treatment of GERD. The use of alginates was also recommended as adjunctive therapy when GERD symptoms were only partially responsive to PPIs.

Abstract
Z-POEM is a minimal invasive surgery result in good outcomes. Z-POEM provide a precision of treatment for Zenker’s diverticulum which reduce recurrence rate. Z-POEM can reduce perforation due to complete view of septal muscle while perform myotomy.
Introduction Zenker’s diverticulum is a rare condition caused by herniation of the mucosa at the pharyngoesophageal junction, resulting in dysphagia. Third-space endoscopic surgery now plays an important role in its management, facilitating precise surgery with good outcomes. The aim of report is to demonstrate technical steps and outcomes of per-oral endoscopic myotomy (Z-POEM). Presentation of case We report two male patients presented with dysphagia. Esophagograms revealed Zenker’s diverticula of 2.1 and 2.0 cm, respectively, and diagnostic gastroscopy showed the diverticula to be 17 cm from the incisors, with tight, thick septal muscle. A 2-cm mucosal incision was made with a triangle-tipped knife, and submucosal tunneling was created by spray coagulation. The gastroscope was advanced into the submucosal space of the esophageal lumen and the diverticulum site until the bottom of the diverticulum could be clearly identified. The septal muscle was completely divided, immediately allowing the gastroscope to pass through easily, and the mucosal defect was reapproximated with hemoclips. Discussion As compared Z-POEM to previous technique; endoscopic septotomy, staple-assisted diverticulotomy, or open neck surgery, Z-POEM is less recurrent of symptoms and complications. Different types of endoscopic knife and lifting materials were used, but all provided the same outcomes. Most of the cases use though-the-scope clips to close the mucosal defect. Conclusion Z-POEM provided precise treatment and complete view of the entire septal muscle can helps to avoid inadequate myotomy.

Abstract
Tracheoesophageal fistulas (TEFs) have traditionally been managed surgically, but the endoscopic approach is widely performed as a less invasive alternative. Different closure techniques have been proposed with inconsistent results. An over-the-scope clip (OTSC) appears to be a reasonable option, but long-term results have not been well defined.

Abstract
Background and study aims Endoscopic submucosal dissection (ESD) enables en bloc removal of colorectal neoplasms regardless of size. Submucosal fibrosis is a significant factor for technical difficulty and poor outcomes. We assessed the predictive factors for severe submucosal fibrosis and the ESD outcomes. Patients and methods Patients undergoing ESD from January 2006 to September 2017 were retrospectively reviewed. The degree of submucosal fibrosis was classified into three types: no fibrosis (F0), mild fibrosis (F1), and severe fibrosis (F2). F0 and F1 cases were grouped as non-severe fibrosis for comparison with the severe fibrosis group. Predictors of severe submucosal fibrosis and ESD outcomes were evaluated. Results ESD was performed in 524 lesions (60 % male; mean age, 67.8 years). Eighty lesions with severe fibrosis (15.3 %) were observed. The overall en bloc resection rate and curative resection rate were 94.3 % and 77.7 %, respectively. Rates of en bloc resection (91.2 % vs. 94.8 %, P = 0.2) and perforation (7.5 % vs. 5.6 %, P = 0.45) were no different between severe fibrosis and non-severe fibrosis groups. However, incidences of non-curative resection and low resection speed were significantly higher in the severe fibrosis group. Among protruding lesions, tumor height and volume were significantly greater in the severe counterparts. A diameter ≥ 40 mm, endoscopic finding of the tumor beyond fold, and fold convergence were independent risk factors for severe fibrosis. Conclusions Severe submucosal fibrosis is a significant risk factor for non-curative resection and a long procedural time. Tumor size and morphology might help to predict the severity of fibrosis.

Abstract
The management of dyspepsia in limited-resource areas has not been established. In 2017, key opinion leaders throughout Thailand gathered to review and evaluate the current clinical evidence regarding dyspepsia and to develop consensus statements, rationales, levels of evidence, and grades of recommendation for dyspepsia management in daily clinical practice based on the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) approach. This guideline is mainly focused on the following 4 topics: (1) evaluation of patients with dyspepsia, (2) management, (3) special issues (overlapping gastroesophageal reflux disease/irritable bowel syndrome and non-steroidal anti-inflammatory drug/aspirin use), and (4) long-term follow-up and management to provide guidance for physicians in Thailand and other limited-resource areas managing such patients.

Abstract
The concept of consuming microorganisms in the treatment of a medical condition and in health maintenance has gained much attraction, giving rise to an abundance of medical claims and of health supplements. This study identified relevant clinical questions on the therapeutic use of probiotics and reviewed the literature in irritable bowel syndrome, inflammatory bowel disease, impaired intestinal immunity, liver disease, intestinal infections, and common childhood digestive disorders. Statements were developed to address these clinical questions. A panel of experienced clinicians was tasked to critically evaluate and debate the available data. Both consensus and contentious statements are presented to provide to clinicians a perspective on the potential of probiotics and importantly their limitations.

Abstract
BACKGROUND AND AIM Current treatments of functional dyspepsia (FD) are unsatisfied. Tricyclic antidepressants alter visceral hypersensitivity and brain-gut interaction. We assessed the efficacy and safety of nortriptyline in patients with FD. METHODS Patients diagnosed with FD according to Rome III criteria who failed to respond to proton pump inhibitor and prokinetic treatment were randomly assigned to either once daily 10-mg nortriptyline or placebo. The primary endpoint was the rate of responders defined as > 50% reduction in dyspepsia symptom score after 8 weeks of treatment. The secondary endpoints were improvement in quality of life as assessed by 36-Item Short Form Health Survey score and safety. RESULTS Sixty-one patients (nortriptyline 28 and placebo 33) were enrolled. Dyspepsia symptom score and duration of symptoms were balanced at entry between both groups. Eight and seven patients in nortriptyline and placebo groups were lost to follow up. Seven patients withdrew due to mild adverse events (nortriptyline 1 and placebo 6). Overall, 19 with nortriptyline and 20 with placebo completed the study. Patients receiving nortriptyline did not achieve higher response rate than those in placebo in both intention-to-treat (53.6% vs 57.6%, P = 0.75) and per-protocol (76.5% vs 73.7%, P = 1.00) analyses. Nortriptyline did not provide improvement in quality of life. The mean difference was 3.8 (P = 0.36) and 0.88 (P = 0.86) by intention-to-treat and 2.9 (P = 0.57) and 3.5 (P = 0.57) by per-protocol analyses in physical and mental component, respectively. All adverse events were minor and similar in both groups. CONCLUSION Nortriptyline was not superior to placebo in management of patients with FD.

Abstract
Helicobacter pylori (H. pylori) infection remains to be the major cause of important upper gastrointestinal diseases such as chronic gastritis, peptic ulcer, gastric adenocarcinoma, and mucosa-associated lymphoid tissue lymphoma. H. pylori management in ASEAN: the Bangkok consensus report gathered key opinion leaders for the region to review and evaluate clinical aspects of H. pylori infection and to develop consensus statements, rationales, and grades of recommendation for the management of H. pylori infection in clinical practice in ASEAN countries. This ASEAN Consensus consisted of 34 international experts from 10 ASEAN countries, Japan, Taiwan, and the United States. The meeting mainly focused on four issues: (i) epidemiology and disease association; (ii) diagnostic tests; (iii) management; and (iv) follow-up after eradication. The final results of each workshop were presented for consensus voting by all participants. Statements, rationale, and recommendations were developed from the available current evidence to help clinicians in the diagnosis and treatment of H. pylori and its clinical diseases.

Abstract
Background/Aims To investigate the effects of esomeprazole and rebamipide combination therapy on symptomatic improvement in patients with reflux esophagitis. Methods A total of 501 patients with reflux esophagitis were randomized into one of the following two treatment regimens: 40 mg esomeprazole plus 300 mg rebamipide daily (combination therapy group) or 40 mg esomeprazole daily (monotherapy group). We used a symptom questionnaire that evaluated heartburn, acid regurgitation, and four upper gastrointestinal symptoms. The primary efficacy end point was the mean decrease in the total symptom score. Results The mean decreases in the total symptom score at 4 weeks were estimated to be -18.1±13.8 in the combination therapy group and -15.1±11.9 in the monotherapy group (p=0.011). Changes in reflux symptoms from baseline after 4 weeks of treatment were -8.4±6.6 in the combination therapy group and -6.8±5.9 in the monotherapy group (p=0.009). Conclusions Over a 4-week treatment course, esomeprazole and rebamipide combination therapy was more effective in decreasing the symptoms of reflux esophagitis than esomeprazole monotherapy.

Abstract
Although gastroesophageal reflux disease is not as common in Asia as in western countries, the prevalence has increased substantially during the past decade. Gastroesophageal reflux disease is associated with considerable reductions in subjective well-being and work productivity, as well as increased healthcare use. Proton pump inhibitors (PPIs) are currently the most effective treatment for gastroesophageal reflux disease. However, there are limitations associated with these drugs in terms of partial and non-response. Dexlansoprazole is the first PPI with a dual delayed release formulation designed to provide 2 separate releases of medication to extend the duration of effective plasma drug concentration. Dexlansoprazole has been shown to be effective for healing of erosive esophagitis, and to improve subjective well-being by controlling 24-hour symptoms. Dexlansoprazole has also been shown to achieve good plasma concentration regardless of administration with food, providing flexible dosing. Studies in healthy volunteers showed no clinically important effects on exposure to the active metabolite of clopidogrel or clopidogrel-induced platelet inhibition, with no dose adjustment of clopidogrel necessary when coprescribed. This review discusses the role of the new generation PPI, dexlansoprazole, in the treatment of gastroesophageal reflux disease in Asia.

Abstract
Management of Helicobacter pylori infection is an important aspect of many upper gastrointestinal tract diseases, such as chronic gastritis, peptic ulcer disease, gastric cancer and mucosa-associated lymphoid tissue (MALT) lymphoma. The Thailand Consensus on H. pylori treatment 2015 consisted of 22 national experts who took active roles, discussed all important clinical information and investigated clinical aspects in four workshops, focuising on: (1) Diagnosis (2) Treatment (3) Follow-up after eradication and (4) H. pylori infection and special conditions. Experts were invited to participate on the basis of their expertise and contribution to H. pylori works and/or consensus methodology. The results of each workshop were taken to a final consensus vote by all experts. Recommendations were developed from the best evidence and availability to guide clinicians in management of this specific infection associated with variety of clinical outcomes.

Abstract
Background/Aims This integrated analysis aimed to identify the factors associated with the most frequently reported treatment-emergent adverse events (TEAEs) in Asian and non-Asian patients with chronic constipation (CC) who receive prucalopride or placebo over 12 weeks. Methods Pooled data from four randomized, double-blind, placebo-controlled, multicenter, phase III studies (NCT00488137, NCT00483886, NCT00485940, and NCT01116206) on patients treated with prucalopride 2 mg or placebo were analyzed. The associations between predictors and TEAEs were evaluated based on a logistic regression model. Results Overall, 1,821 patients (Asian, 26.1%; non-Asian, 73.9%) were analyzed. Prucalopride treatment was significantly associated with diarrhea, headache, and nausea (p<0.001), but not with abdominal pain, compared with placebo. Differences in the prevalence of TEAEs between prucalopride and placebo decreased greatly after the first day of treatment. Compared with non-Asians, Asians were more likely to experience diarrhea and less likely to develop abdominal pain, headache, and nausea. Prior laxative use, CC duration, and body weight were not predictive of any of these TEAEs. Conclusions Prucalopride treatment was positively associated with diarrhea, headache, and nausea. Asian patients tended to have a higher frequency of diarrhea but lower frequencies of headache, abdominal pain, and nausea compared with non-Asians.

Abstract
BACKGROUND AND AIM Data on patient satisfaction with proton pump inhibitor (PPI) therapy for gastroesophageal reflux disease (GERD) are scarce in Asia. The perspectives of Asian patients with GERD and their satisfaction with PPI therapy were investigated. METHODS The GERD in Asia Pacific Survey (GAPS) was conducted from December 2011 to March 2012. Patients aged 21-55 years with self-reported doctor-diagnosed GERD, who had experienced symptoms in the previous 12 months, and were currently taking PPIs were enrolled. After a pilot study, a questionnaire was completed by respondents from six Asian countries during face-to-face interviews. RESULTS A total of 450 patients with GERD participated in the GAPS. Although the respondents generally complied with treatment, response to therapy was only partially successful. Most respondents indicated that PPIs eliminated pain (72%), took effect within 30 min (76%), provided sustained relief (73%), and provided nocturnal relief (77%). However, 45% of respondents reported limited improvement in nocturnal symptoms, and 49% continued to take adjunctive therapy to manage their symptoms. After treatment, respondent's "well-being" had improved. However, GERD still had a negative impact on well-being for 76% of respondents after treatment, compared with 94% before treatment. CONCLUSIONS Asian patients reported a negative impact of GERD on their daily lives. Many respondents continued to experience symptoms despite reporting good compliance with PPI therapy, emphasizing the shortcomings of currently available therapy for GERD. This survey is the first to highlight Asian patients' perspectives of GERD and PPI therapy, and provides a platform for further evaluation.

Abstract
Background/Aims To compare the efficacy and safety of prucalopride, a novel selective high-affinity 5-hydroxytryptamine type 4 receptor agonist, versus placebo, in Asian and non-Asian women with chronic constipation (CC). Methods Data of patients with CC, receiving once-daily prucalopride 2-mg or placebo for 12-weeks, were pooled from 4 double-blind, randomized, phase-III trials (NCT00488137, NCT00483886, NCT00485940 and NCT01116206). The efficacy endpoints were: average of ≥ 3 spontaneous complete bowel movements (SCBMs)/week; average increases of ≥ 1 SCBMs/week; and change from baseline in each CC-associated symptom scores (bloating, abdominal pain, hard stool and straining). Results Overall, 1,596 women (Asian [26.6%], non-Asian [73.4%]) were included in this analysis. Significantly more patients in the prucalopride group versus placebo experienced an average of ≥ 3 SCBMs/week in Asian (34% vs. 11%, P < 0.001) and non-Asian (24.6% vs. 10.6%, P < 0.001) subgroups. The number of patients reporting an increase of ≥ 1 SCBMs/week from baseline was significantly higher in the prucalopride group versus placebo among both Asian (57.4% vs. 28.3%, P < 0.001) and non-Asian (45.3% vs. 24.0%, P < 0.001) subgroups. The difference between the subgroups was not statistically significant. Prucalopride significantly reduced the symptom scores for bloating, hard stool, and straining in both subgroups. Conclusions Prucalopride 2-mg once-daily treatment over 12-weeks was more efficacious than placebo in promoting SCBMs and improvement of CC-associated symptoms in Asian and non-Asian women, and was found to be safe and well-tolerated. There were numeric differences between Asian and non-Asian patients on efficacy and treatment emergent adverse events, which may be partially due to the overlap with functional gastrointestinal disorders in non-Asian patients.

Abstract
BACKGROUND/AIMS To report gastric emptying scintigraphy, normal values should be established for a specific protocol. The aim of this study was to provide normal gastric emptying values and determine factors affecting gastric emptying using Asian rice-based meal in healthy volunteers. METHODS One hundred and ninety-two healthy volunteers were included at 7 tertiary care centers across Thailand. Gastric emptying scintigraphy was acquired in 45 degree left anterior oblique view immediately after ingestion of a 267 kcal steamed-rice with technetium-99m labeled-microwaved egg meal with 100 mL water for up to 4 hours. RESULTS One hundred and eighty-nine volunteers (99 females, age 43 ± 14 years) completed the study. The medians (5-95th percentiles) of lag time, gastric emptying half time (GE T1/2) and percent gastric retentions at 2 and 4 hours for all volunteers were 18.6 (0.5-39.1) minutes, 68.7 (45.1-107.8) minutes, 16.3% (2.7-49.8%) and 1.1% (0.2-8.8%), respectively. Female volunteers had significantly slower gastric emptying compared to male (GE T1/2, 74 [48-115] minutes vs. 63 (41-96) minutes; P < 0.05). Female volunteers who were in luteal phase of menstrual cycle had significantly slower gastric emptying compared to those in follicular phase or menopausal status (GE T1/2, 85 [66-102] mintes vs. 69 [50-120] minutes or 72 [47-109] minutes, P < 0.05). All of smoking volunteers were male. Smoker male volunteers had significantly faster gastric emptying compared to non-smoker males (GE T1/2, 56 [44-80] minutes vs. 67 [44-100] minutes, P < 0.05). Age, body mass index and alcohol consumption habits did not affect gastric emptying values. CONCLUSIONS A steamed-rice with microwaved egg meal was well tolerated by healthy volunteers. Gender, menstrual status and smoking status were found to affect solid gastric emptying.

Abstract
BACKGROUND The advent of double-balloon enteroscopy has enabled more accurate diagnosis and treatment of small bowel disorders. Single-balloon enteroscopy permits visualization of the entire small intestine less often than does double-balloon enteroscopy. However, the relative clinical advantages of the 2 methods remain controversial. This study therefore aimed to identify the indications for and therapeutic impact of performing single-balloon enteroscopy. METHODS We retrospectively reviewed prospectively collected data from adults who underwent single-balloon enteroscopy from January 2007 through November 2011 and analyzed their baseline characteristics, endoscopic findings, pathological diagnoses, and clinical outcomes. RESULTS A total of 145 procedures were performed in 116 patients with a mean age of 58.1 ± 17.7 years (range, 18-89 years). The most common indications for performing single-balloon enteroscopy were overt gastrointestinal (GI) bleeding, chronic diarrhea, and occult GI bleeding, accounting for 57.9%, 12.4%, and 9.7% of the patients, respectively. The area of interest was achieved in 80.7% of the cases, with a 5.5% rate of technical failure. An overall positive finding was detected in 65.5% of the cases, of which 33.8% were ulcers and erosions; 8.3%, masses; and 3.4%, angiodysplasia. The diagnostic yields were 42.9%, 52.4%, 78.6%, 50.0%, and 25.0% for patients with overt GI bleeding, occult GI bleeding, abdominal pain, chronic diarrhea, and abnormal imaging results, respectively. Therapeutic procedures were performed in 11% of patients with GI bleeding and achieved a therapeutic yield of 14.6% with a minor complication rate of 11.7%. CONCLUSIONS Single-balloon enteroscopy was effective for the diagnosis and treatment of small bowel disorders, especially in patients who presented with abdominal pain, GI bleeding, or focal abnormalities on imaging scans.

Abstract
AIM: To determine the factors associated with clinical outcomes and complications of Histoacryl® glue injection for acute gastric variceal hemorrhage.
METHODS: Patients who presented to the Siriraj Gastrointestinal Endoscopy Center with active gastric variceal bleeding and were admitted for treatment between April 2008 and October 2011 were selected retrospectively for study inclusion. All bleeding varices were treated by injection of Histoacryl® tissue glue (B. Braun Melsungen AG, Germany) through a 21G or 23G catheter primed with lipiodol to prevent premature glue solidification. Data recorded for each patient included demographic and clinical characteristics, endoscopic findings, clinical outcomes in terms of early and late re-bleeding, mortality, and procedure-related complications. Data from admission (baseline) and post-treatment were comparatively analyzed using stepwise logistic regression analysis to determine the correlation between factors and clinical outcomes.
RESULTS: A total of 90 patients underwent Histoacryl® injection to treat bleeding gastric varices. The mean age was 55.9 ± 13.9 (range: 15-88) years old, and 74.4% of the patients were male. The most common presentations were hematemesis (71.1%), melena (12.2%), and coffee ground emesis (8.9%). Initial hemostasis was experienced in 97.8% of patients, while re-bleeding within 120 h occurred in 10.0%. The presence of ascites was the only factor associated with early and late re-bleeding [odds ratio (OR) = 10.67, 95%CI: 1.27-89.52, P = 0.03 and OR = 4.15, 95%CI: 1.34-12.86, P = 0.01, respectively]. Early procedure-related complications developed in 14.4% of patients, and were primarily infections and non-fatal systemic embolization. Late re-bleeding was significantly correlated with early procedure-related complications by univariate analysis (OR = 4.01, 95%CI: 1.25-12.87, P = 0.04), but no factors were significantly correlated by multivariate analysis. The overall mortality rate was 21.1%, the majority of which were related to infections. The factors showing strong association with higher mortality risk were elevated total bilirubin (OR = 16.71, 95%CI: 3.28-85.09, P < 0.01), a large amount of transfused fresh frozen plasma (OR = 1.001, 95%CI: 1.000-1.002, P = 0.03), and late re-bleeding (OR = 10.99, 95%CI: 2.15-56.35, P = 0.02).
CONCLUSION: Histoacryl® injection is a safe and effective hemostatic method for treating gastric variceal hemorrhage. Patients with compromised liver, including ascites, have a higher risk of re-bleeding.

Abstract
Gastric antral vascular ectasia (GAVE) accounted for 4% of non-variceal gastrointestinal hemorrhage. Even though unclear pathogenesis, GAVE often associated with chronic renal failure, autoimmune diseases and cirrhosis. Asymptomatic lesions were reasonably not to treated. The treatment options for GAVE are non-endoscopic and endoscopic treatments. For the pharmacological treatment, some success were reported for the use of octreotide, thalidomide and tranexamic acid. While the endoscopic treatment is the mainstay for treatment of symptomatic lesions. The endoscopic ablative therapies such as argon plasma coagulation was reported with good clinical outcomes. However, these treatment options had some limitation due to the need of special equipment and multiple sessions needed to control the bleeding. We reported another treatment option using the routine-achievable instrument such as endoscopic band ligation as an initial treatment which also provided a good treatment outcome and less sessions.

Abstract
INTRODUCTION Endoscopic retrograde cholangiopancreatography (ERCP) and endoscopic ultrasonography (EUS) procedures in elderly patients are on the rise, and they play an important role in the diagnosis and management of various gastrointestinal diseases. The use of deep sedation in these patients has been established as a safe and effective technique in Western countries; however, it is uncertain if the situation holds true among Asians. The present study aimed to evaluate the age-dependent safety analysis and clinical efficacy of propofol-based deep sedation (PBDS) for ERCP and EUS procedures in adult patients at a World Gastroenterology Organization (WGO) Endoscopy Training Center in Thailand. METHODS We undertook a retrospective review of anesthesia or sedation service records of patients who underwent ERCP and EUS procedures. All procedures were performed by staff endoscopists, and all sedations were administered by anesthesia personnel in the endoscopy room. RESULTS PBDS was provided for 491 ERCP and EUS procedures. Of these, 252 patients (mean age, 45.1 + 11.1 years, range 17-65 years) were in the <65 age group, 209 patients (mean age, 71.7 + 4.3 years, range 65-80 years) were in the 65-80 year-old group, and 30 patients (mean age, 84.6 + 4.2 years, range 81-97 years) were in the >80 age group. Common indications for the procedures were pancreatic tumor, cholelithiasis, and gastric tumor. Fentanyl, propofol, and midazolam were the most common sedative drugs used in all three groups. The mean doses of propofol and midazolam in the very old patients were relatively lower than in the other groups. The combination of propofol, midazolam, and fentanyl, as well as propofol and fentanyl, were frequently used in all patients. Sedation-related adverse events and procedure-related complications were not statistically significantly different among the three groups. Hypotension was the most common complication. CONCLUSION In the setting of the WGO Endoscopy Training Center in a developing country, PBDS for ERCP and EUS procedures in elderly patients by trained anesthesia personnel with appropriate monitoring is relatively safe and effective. Although adverse cardiovascular events, including hypotension, in this aged group is common, all adverse events were usually transient, mild, and easily treated, with no sequelae.

AIM: To characterize the effects of age on clinical presentations and endoscopic diagnoses and to determine outcomes after endoscopic therapy among patients aged ≥ 65 years admitted for acute upper gastrointestinal bleeding (UGIB) compared with those aged < 65 years.
METHODS: Medical records and an endoscopy data-base of 526 consecutive patients with overt UGIB ad-mitted during 2007-2009 were reviewed. The initial presentations and clinical course within 30 d after endoscopy were obtained.
RESULTS: A total of 235 patients aged ≥ 65 years constituted the elderly population (mean age of 74.2 ± 6.7 years, 63% male). Compared to young patients, the elderly patients were more likely to present with melena (53% vs 30%, respectively; P < 0.001), have comorbidities (69% vs 54%, respectively; P < 0.001), and receive antiplatelet agents (39% vs 10%, respectively; P < 0.001). Interestingly, hemodynamic instability was observed less in this group (49% vs 68%, respectively; P < 0.001). Peptic ulcer was the leading cause of UGIB in the elderly patients, followed by varices and gastropathy. The elderly and young patients had a similar clinical course with regard to the utilization of endoscopic therapy, requirement for transfusion, duration of hospital stay, need for surgery [relative risk (RR), 0.31; 95% confidence interval (CI), 0.03-2.75; P = 0.26], rebleeding (RR, 1.44; 95% CI, 0.92-2.25; P = 0.11), and mortality (RR, 1.10; 95% CI, 0.57-2.11; P = 0.77). In Cox’s regression analysis, hemodynamic instability at presentation, background of liver cirrhosis or disseminated malignancy, transfusion requirement, and development of rebleeding were significantly associated with 30-d mortality.
CONCLUSION: Despite multiple comorbidities and the concomitant use of antiplatelets in the elderly patients, advanced age does not appear to influence adverse outcomes of acute UGIB after therapeutic endoscopy.

Abstract
BACKGROUND The low-density lipoprotein receptor (LDL-R) has been proposed to function as a receptor for the hepatitis C virus (HCV) entry. Polymorphism of LDL-R gene may influence the clearance of virus and response to treatment. This study was conducted to evaluate the association of LDL-R gene polymorphism and the response to antiviral treatment in patients with chronic HCV infection. MATERIAL AND METHOD A total of 112 naïve patients with HCV genotype 3 were enrolled in the study. All patients were treated with a combination of pegylated interferon and ribavirin for 24 weeks. Polymerase chain reaction combined with restriction fragment length polymorphism was used to detect the polymorphism at the LDL-R gene intron 11 loci, including intron1, intron 3.1, intron 3.2, intron 4, intron 6, exon 8, intron 11, intron 13, intron 14 and 3'UTR-2 SNPs in intron 16 region. Comparisons of genotype and allele frequency between responders and nonresponders were analyzed. RESULTS Patients had a mean age of 54 years and 43% were male. Mean HCVRNA viral load and alanine aminotransferase level were 6.3 log, IU/mL and 100 IU/L, respectively. Sustained virological response, relapse and no response were documented in 68.7%, 17.9% and 13.4%, respectively. Baseline characteristics including age, sex, body weight, aminotransferase levels and HCV RNA viral load were similar between responders and nonresponders. No statistical difference was found for either genotype distribution or allele frequency among responders and nonresponders. CONCLUSION This study did not provide the evidence for a role of LDL-R polymorphism the response to antiviral treatment in patients with HCV genotype 3. This indicates that a genetic component via the LDL-R may not control HCV treatment outcome in HCV genotype 3

Abstract
OBJECTIVE Ginger has been traditionally used to reduce intestinal gas and flatulence. The present study examined the effects of ginger on the esophagus and lower esophageal sphincter (LES) function by esophageal manometry. STUDY DESIGN A randomized controlled trial. SETTING Departments of Physiology and Medicine, Faculty of Medicine Siriraj Hospital. SUBJECTS Fourteen healthy young male volunteers. MATERIAL AND METHOD The effect of ginger (1 gram of dried powder suspended in 100 ml water) on LES and esophageal peristalsis were studied by manometry in 14 healthy young men. Subjects drank 100 ml of water as a control, then performed five wet swallows at 30 minutes after the drink, followed by drinking a ginger suspension and performed five wet swallows at every 30 minutes thereafter for 180 minutes. The esophageal manometry was performed throughout 180 minutes after ginger consumption. The manometric parameters before and after water and ginger intake were compared. RESULTS The present study showed that after 1 gram-ginger consumption, the LES resting pressures remained unchanged but the percent relaxation at swallowing was increased throughout the 180 minutes with statistical significance at 90, 150 and 180 minutes. The amplitude and duration of esophageal contraction were not changed, while the velocity of contraction waves was decreased at 30, 120, 150 and 180 minutes after the drinks. CONCLUSION Ginger did not affect LES pressure at rest or esophageal contractile amplitude and duration when swallowing, but caused more relaxation of the LES and decreased the esophageal contraction velocity, which may cause more chance of gastric gas expel or antiflatulant effect.

Abstract
BACKGROUND AND OBJECTIVE There is no established clinical role for the lens culinaris agglutinin-reactive fraction of alpha-fetoprotein (AFP-L3%) in the management of the Thai hepatocellular carcinoma (HCC) patient population. The aim of this prospective study was to evaluate clinical utility and performance characteristics of AFP-L3% for the diagnosis of HCC in Thai referral patients. MATERIAL AND METHOD Sixty-one histologically proven HCC patients and 35 patients with other liver cancers were included for analysis. RESULTS The HCC population was comprised of 50 males and 11 females, with a mean age of 48.8 years. According to the Okuda system, three were classed as stage I, thirty-five belonged to stages II, and six were classified in stage III. An AFP-L3% a cut-off value of > 15% yielded a sensitivity of 82% (95% confidence interval [CI], 74-88%), specificity of 71% (95% CI, 58-82%), positive predictive value of 83% (95% CI, 75-90), and negative predictive value of 69% (95% CI, 56-80) for the diagnosis of HCC. In HCC patients with AFP of < 200 ng/ml, an AFP-L3% at a cut-off value of > 15% not only maintained high sensitivity of 83% and good specificity of 71% but also increased negative predictive value to 86% for the diagnosis of HCC. CONCLUSION AFP-L3% provides high sensitivity but with lower sensitivity in the diagnosis of HCC than total AFP in individuals with symptomatic liver mass. However, considering its high negative predictive value in patients with AFP < 200 ng/ml, AFP-L3% might be useful as an adjunctive marker, in combination with AFP, to exclude the presence of HCC.

Abstract
PURPOSE This study was designed to evaluate the effects of caffeine on anorectal function by anorectal manometry. METHODS Ten healthy subjects were studied. They drank 200 ml of water and later 200 ml of a solution that contained caffeine 3.5 mg/kg body weight. The anorectal manometric study was divided into three periods: basal, water, and caffeine; each period lasted 45 minutes. RESULTS After the ingestion of water, the basal anal sphincter pressure showed no change during the 45-minute recording, whereas after caffeine consumption the basal anal sphincter pressure increased at 10 minutes (P = 0.047) and 15 minutes (P = 0.037). The average basal anal sphincter pressure throughout the 45 minutes was significantly higher after caffeine ingestion than after water (P = 0.013). After caffeine intake, the maximum squeeze pressure increased significantly (P = 0.017) compared with the basal period. Both water and caffeine consumption caused a decrease in the rectal sensory threshold for the desire to defecate. CONCLUSIONS Caffeine 3.5 mg/kg body weight in 200 ml of water resulted in stronger anal sphincter contractions both at basal period and during voluntary squeeze. The sensory threshold was also decreased, leading to an earlier desire to defecate. Caffeine consumption may result in an earlier desire to defecate, leading to defecation if the anal sphincter can relax voluntarily.

Abstract
STUDY AIMS The aims of this study were to evaluate the efficacy and safety of precut sphincterotomy in relation to the experience of a single endoscopist, and to establish the number of procedures required before achieving an effective and safe precut sphincterotomy. METHODS A total of 200 consecutive patients underwent precut sphincterotomy carried out by a single endoscopist (T.A.) between January 2003 and December 2005. All of the procedures were divided into four chronological groups of 50 (Group I, II, III, and IV). Medical records and patient data were retrospectively reviewed and included procedure indications, outcomes, and complications. All patients were admitted for observation after the procedure in case of complications. RESULTS A total of 200 patients (23.3%) (mean age 58.5 years; 101 men) underwent precut sphincterotomy (161 with needle-knife technique, 32 with septotomy technique, and seven with Erlangen technique). There was no mortality. The success rates of prompt bile duct cannulation after precut sphincterotomy were 88%, 86%, 94%, and 82%, respectively ( P > 0.05). Immediate bleeding requiring a submucosal adrenaline injection was observed in combined group I - II (28%) and combined group III - IV (7%) ( P < 0.05). One patient (2%) from each of group I, III, and IV required further endoscopic treatment for rebleeding. Duodenal perforation (2%) was detected and conservatively treated in one patient from group II. Mild pancreatitis was found in one patient (2%) in group III. CONCLUSIONS The success rates of bile duct cannulation by precut sphincterotomy were not associated with the experience of the endoscopist. The postprocedural complications significantly decreased after the first 100 procedures. An experience of at least 100 procedures is suggested to achieve a safe precut sphincterotomy.

Abstract
AIM: To compare the results and complications of early pre-cutting technique with standard technique.
METHODS: From January 2003 to December 2004, a total of 416 consecutive therapeutic biliary ERCP procedures were performed by one endoscopist (T.A.). Data were retrospectively collected according to procedure indication and results. Of these, 293 procedures (70.4%) were done with standard technique (group A) and 123 procedures (29.6%) with early pre-cutting technique in case of difficult cannulation (group B). The results and complications of ERCP were compared.
RESULTS: Success rate of first attempt cannulation was 98.0% in group A and 87.8% in group B. The overall incidence of post-ERCP pancreatitis, hemorrhage, perforation and cholangitis was 0%, 0.2%, 0.5% and 0.5%, respectively. Morbidity rate was not significantly different. No procedure-related mortality was occurred.
CONCLUSION: For an experienced hand, the early pre-cutting technique for biliary cannulation is safe and effective as standard technique.

Abstract
BACKGROUND Achalasia is a disorder of the esophagus. The lower esophageal sphincter fails to relax and increases the loss of body peristalsis. It is an uncommon disease worldwide. Data regarding its treatment are derived mostly from North America and European countries. Few data regarding this treatment were available in Asia and no data about using botulinum toxin injection for this disease was available in Thailand. OBJECTIVE To evaluate the efficacy of botulinum toxin in achalasia in Thai patients. MATERIAL AND METHOD Eleven achalasia adult Thai patients with a mean age of 56.5 +/- 16.9 were studied. There are nine females and two males. The duration of symptom before treatment was 27.5 +/- 34.5 months. All patients receiving botulinum toxin injection at Siriraj hospital between 2001 and 2006 were retrospectively reviewed. Pretreatment of baseline lower esophageal sphincter, symptom score and body weight were compared. Time to second botulinum toxin injection or the need to receive treatment for recurrence was recorded to evaluate the time of recurrence. Adverse events from this procedure were collected. RESULTS Eleven patients were involved in this study. One patient that received 40 units of botulinum toxin showed no response after a six months follow up. The other ten patients received botulinum toxin 80 units for each session and were enrolled in this study. All ten patients demonstrated good response to the first botulinum toxin injection and subsequent injections. Four patients received only one session of botulinum toxin injection during study period. Meanwhile, five patients received two sessions and only one patient required four sessions. Symptom score of all ten patients improved significantly compared with pretreatment score (7.3 +/- 1.3 for pretreatment and 0.4 +/- 0.5, 0.9 +/- 0.7 and 1.6 +/- 1.3 after 2 weeks, 3 months and 6 months, respectively). Body weight increased significantly when compared with pretreatment (47.7 +/- 6.5 Kg for pretreatment and 49.2 +/- 5.8, 50.5 +/- 6.4, and 50.7 +/- 5.8 Kg after 2 weeks, 3 months, and 6 months, respectively). Previous treatments prior botulinum toxin injection do not seem to influence the effect of this treatment. Mean time of recurrence is 444 +/- 132 days (270-718 days). Minor adverse events such as chest pain and reflux symptoms were seen in this therapy. CONCLUSION Botulinum toxin injection in Thai achalasia patients is an effective, simple, and safe treatment. These results showed the similar outcomes as in Caucasian patients.

Abstract
Caffeine affects many aspects of body function including the gastrointestinal system. A single-blinded experimental study was performed to evaluate the effect of caffeine on lower esophageal sphincter (LES) and esophageal peristaltic contractions in healthy Thai adults. The volunteers were six men and six women aged 19-31 years. Subjects drank 100 mL of water. Five wet swallows were performed 30 min after the drink. The basal LES pressure was continuously measured using esophageal manometric technique. They then consumed another 100 mL of water containing caffeine at the dose of 3.5 mg/kg body weight. The swallows and basal LES pressure monitoring were repeated. The results showed no change in basal LES pressure after a water drink while caffeine consumption significantly lowered the pressure at 10, 15, 20 and 25 min. The mean amplitude of contractions and peristaltic velocity were decreased at the distal esophagus at 3 and 8 cm above LES. The mean duration of contraction was decreased at the distal part but increased at the more proximal esophagus. The heart rate, systolic and diastolic blood pressures were increased significantly at 10-20 min after caffeine ingestion. This study indicated that caffeine 3.5 mg/kg affected esophageal function, resulting in a decrease in basal LES pressure and distal esophageal contraction, which is known to promote the reflux of gastric contents up into the esophagus.

Abstract
Clinicopathologic information of gastrointestinal (GI) lymphoma in Southeast Asia is lacking. A retrospective analysis of 120 cases of GI lymphoma in Thailand diagnosed at Siriraj Hospital based on WHO classification was performed. All were non-Hodgkin lymphoma (NHL). The peak age was in the sixth and seventh decades; a slight male preponderance was observed. Sites of involvement included stomach (49.2%), intestine (46.7%), and multiple sites (4.2%). There were 104 cases of primary GI lymphoma (86.7%) and 16 cases of secondary GI lymphoma (13.3%). Presenting GI symptoms were more common in the former; while superficial lymphadenopathy and fever were more common in the latter. Mass lesions were observed in both groups (72.1% vs 56.3%). Localized and advanced diseases were found in 68.3% and 31.7% of primary GI lymphomas, respectively. The most common type of lymphoma in both groups was diffuse large B-cell lymphoma. Lymphoepithelial lesions (LEL) were not significantly different between the two groups (58.2% vs 42.9%), but Helicobacterpylori infection was significantly associated with primary gastric lymphoma (p < 0.0001). The treatment of choice for localized primary GI lymphoma is controversial. Complete surgical resection may increase the chance of complete remission, but mortality and relapse rates might be higher than those observed with combination chemotherapy alone. GI lymphomas in Thailand are mostly primary B-cell NHL. LEL is not indicative of primary GI lymphoma, but H. pylori infection is closely associated with primary gastric lymphoma. A prospective study to determine the treatment of choice for localized GI lymphoma is needed.

Abstract
Irritable bowel syndrome (IBS) is a functional bowel disorder in which abdominal pain is associated with a defect or a change in bowel habits. Subtle inflammation, especially after infectious enteritis, has been sometimes suspected as one mechanism of pathogenesis. This research was performed (1) to evaluate the prevalence of parasitic infections and (2) the possible association of IBS and parasitic infections. Fifty-nine IBS patients were recruited using symptom-based criteria (Rome Criteria II) with an absence of intestinal parasitic infection by direct smear method. Stool samples of individual patients were examined using 7 methods, ie examination for stool occult blood, simple saline smear method, formalin-ether technique, culture for Blastocystis hominis, modified trichrome stain, modified Ziehl-Neelsen method, and trichrome stain for parasitic and bacterial infections. Of the 59 patients, stool samples of 13 patients (22.1%) were positive for parasites. These were B. hominis (13.6%), Strongyloides stercoralis larvae (1.7%), Giardia lamblia cysts (1.7%), and non-pathogenic protozoa, ie Endolimax nana cysts (5.1%). The prevalence rate of parasitic infections in the control group (20%) was not statistically different from the patients. There was no statistical difference between B. hominis infection in IBS patients and control was found in this study (p = 0.87). In the IBS group, B. hominis infection predominated (13.6%), while other parasitic infections were found in 8.5%. The culture method for B. hominis is more sensitive than the direct (simple) stool smear method, which is the routine diagnostic method in most laboratories. These results were also found in control group.

Abstract
BACKGROUND AND OBJECTIVES Diseases of the distal gastrointestinal tract are becoming more common among Thai people especially in the elderly. Manometry is a new and useful technique in the diagnosis and management of anorectal disorders. This cross-sectional study aimed to measure anorectal manometric parameters in normal Thai subjects. MATERIAL AND METHOD Thirty healthy Thai subjects (17 males and 13 females) were studied. They completed a questionnaire assessing their bowel function. A water-perfused manometric system with non-pull-through technique was used to monitor pressure in the rectum and anus. All subjects were asked to squeeze the anal sphincters, bear down, then blow up a party balloon. Rectal sensation and recto-anal inhibitory reflex were also assessed by intermittent phasic balloon distention. Simulated defecation or balloon expulsion test was also performed. RESULT The study revealed the following anorectal manometric parameters. The mean with standard deviation of the resting, squeezed, and sustained squeezed pressures were 55.4 +/- 15.3, 170.3 +/- 81.7 and 109.3 +/- 54.4 mm Hg respectively. Men had a longer anal sphincter (p = 0.01) and higher squeezed, and sustained squeezed pressures (p < 0. 001) compared to women, while their resting sphincter pressures were similar. Threshold volumes for rectal sensation and desire to defecate were not different among male and female subjects, but the threshold for urgency to defecate was higher in men. The study yielded normal anorectal manometric parameters in Thai subjects. Some parameters vary with gender. It is difficult to compare these normal ranges in Thai subjects to those in Caucasians, as the number of subjects is rather small and the details of instruments and techniques always vary from lab to lab. The manometric findings in these Thai subjects create more understanding in anorectal physiology and can be used as a guideline for the investigation of anorectal function in a symptomatic Thai population in a motility clinic.

Abstract
BACKGROUND Laparoscopic cholecystectomy (LC) has become the treatment of choice for patients with symptomatic cholelithiasis. About 8-15 per cent of patients with symptomatic gallstones may bear associated common bile duct (CBD) stones, The management of choledocholithiasis in the laparoscopic era remain debatable. Although pre-operative endoscopic cholangiopancreatography (ERCP) is available and highly accurate in the detection of CBD stones, its routine use is controversial because of its inherent disadvantages. OBJECTIVE The aim of this retrospective study was to generate an effective predictive model for bile duct stones detection by pre-operative ERCP. METHOD Twelve pre-operative clinical, biochemical and sonographic variables from 206 consecutive patients who underwent pre-operative ERCP with LC for gallstones with/without CBD stones from October 1998 to December 2000 were retrospectively analysed RESULTS 143 of the 206 patients with gallstones were found to have CBD stones. The mean age was 61 (20-93) yr old, and 55.9 per cent were female. Multivariate analysis showed a high predictive value for the presence of CBD stones in patients aged > or = 55 yr old (Odd radio (OR) 1.03, 95% confidence interval (95% CI) 1.01-1.05), jaundice (OR 2.7, 95% CI 1.7-4.8), elevated alkaline phosphatase (OR 1.002, 95% CI 1.000-1.005), CBD dilatation on ultrasound (OR 3.8, 95% CI 1.8-8) and CBD stone on ultrasound. CONCLUSION The important clinical presentations and investigating could allow more appropriate use of pre-operative ERCP in patients who have symptomatic gallstones with a suspected CBD stone prior to cholecystectomy.

Abstract
BACKGROUND It has been unclear as to whether the Rome II criteria could be applied to patients in the Asia region with functional gastrointestinal (GI) diseases. The aim of the present study was to determine if symptoms of Asian patients with functional gastrointestinal disorders formed groups which corresponded to the Rome II diagnostic criteria. METHODS A modified English version of Talley's bowel disease questionnaire was developed in collaboration with various research teams in accordance with the Rome II criteria. This instrument was translated into the local languages of the following nine Asian regions: China, Hong Kong, Indonesia, Korea, Malaysia, Singapore, Taiwan, Thailand and Vietnam. From September to December 2001, newly enrolled outpatients attending 14 GI or medical clinics in these regions were invited to complete the questionnaire. From these respondents, patients with functional gastrointestinal disorders fulfilling the '12 weeks out of 12 months' criteria were separated for further analysis. Principal component factor analysis with varimax rotation was used to identify symptom clusters or factors. These factors were compared with the existing classification of functional GI diseases derived from the Rome II criteria. RESULTS Factor analysis of symptoms from 1012 functional GI patients supported the Rome II classification of the following groups of functional GI disorders: diarrhea-predominant irritable bowel syndrome, functional constipation, functional dyspepsia, functional abdominal pain syndrome, functional heartburn, and functional vomiting. Functional diarrhea was combined with functional anorectal disorders, and globus merged with functional dysphagia into one factor. Some of the functional dyspepsia, abdominal bloating and belching symptoms were loaded into one factor. CONCLUSIONS Factor analysis of symptoms from a sample of Asian patients with functional GI disorders partially supported the use of the Rome II classification.

Abstract
To explore the hypothesis that denervation hypersensitivity increases ileocolonic motor activity after extrinsic denervation, we compared muscarinic neurotransmission in canine ileocolonic loops that were isolated and either extrinsically innervated or extrinsically denervated. We recorded ileal, ileocolonic sphincter (ICS) and colonic pressures, and colonic tone, compliance and relaxation during ileal distention. Muscarinic effects were probed by neostigmine, and minimally effective doses of muscarinic receptor antagonists. Denervation augmented ileal, ICS and colonic contractile activity; colonic high-amplitude propagating contractions (HAPCs) were also augmented; colonic relaxation during ileal distention was abolished. Neostigmine induced HAPCs in both loop preparations. Pirenzipine (M1 antagonist) reduced ileal contractile activity in all loops and reduced colonic relaxation during ileal distention in innervated loops. Pirenzipine also reduced colonic tone and colonic HAPCs, more in denervated loops. Darifenacin (M3 antagonist) reduced ileocolonic contractile activity and tone more than did AF-DX 116 (M2 antagonist) in all loops. Cholinergic receptor subtypes modulate different facets of ileocolonic motor activity in the canine ileocolonic region. Increased sensitivity at M1 muscarinic receptors may partly account for the effects of extrinsic denervation.

Abstract
The human colon can dilate, often to life-threatening proportions. Our aim was to explore nitrergic mechanisms underlying colonic dilation in conscious dogs with enterically isolated ileocolonic loops either extrinsically innervated (n = 4) or extrinsically denervated (n = 4). We recorded phasic pressures in ileum and ileocolonic sphincter (ICS), colonic tone, compliance, and relaxation during ileal distension. By NADPH-diaphorase histochemistry, we assessed effects of extrinsic denervation and enteric isolation on nitrergic fibers. Extrinsic denervation increased phasic pressures in ileum, ICS, and colon and abolished ICS and colonic relaxation in response to ileal distension. The nitric oxide synthase (NOS) inhibitor N(omega)-nitro-L-arginine (L-NNA) increased phasic pressures at all sites and ICS tone but did not abolish colonic relaxation during ileal distension in innervated loops. L-NNA reduced compliance and induced colonic high-amplitude propagated contractions in denervated loops. The NOS substrate donor L-arginine reversed effects of L-NNA. The number of NADPH-diaphorase fibers increased in both enterically isolated preparations. Nonnitrergic extrinsic nerve pathways mediate reflex colonic relaxation during ileal distension. Enteric isolation augments the number of NOS fibers, an effect not modified by extrinsic denervation.

Abstract
BACKGROUND Studies in animals indicate that endogenous nitric oxide (NO) is an important inhibitory neurotransmitter in the gastrointestinal tract and that it modulates food intake. We evaluate the role of NO mechanisms in mediating the effects of small intestinal nutrients on antropyloroduodenal motility and appetite in humans. METHODS On 2 separate days, 8 healthy adult men received intravenous L-NAME 180 microg/kg/h or 0.9% saline (0-150 min); between 30 min and 120 min, an intraduodenal lipid infusion (2 kcal/min) was administered, and at 120 min subjects were offered a buffet meal (120-150 min). Antropyloroduodenal pressures were measured with a sleeve/sidehole manometric assembly. During the infusions, perceptions of hunger and fullness were assessed with visual analog questionnaires and amount and macronutrient content of food consumed at the buffet meal were quantified. Blood pressure and heart rate were monitored at regular intervals. RESULTS Intraduodenal lipid infusion was associated with increases in fullness (P < 0.05) and in frequency of isolated pyloric pressure waves (P < 0.05) and basal pyloric pressure (P < 0.05); and decreases in hunger (P < 0.05) and in frequency of antral (P < 0.05) and duodenal (P < 0.05) pressure waves. L-NAME increased diastolic blood pressure (P = 0.08) and decreased heart rate (P < 0.05), but had no effect on antropyloroduodenal pressures or food intake. CONCLUSIONS Intravenous administration of the systemic NO synthase inhibitor, L-NAME, in a dose that affects cardiovascular function in healthy humans does not modify the antropyloroduodenal motor and appetite responses to intraduodenal lipid infusion.

Abstract
UNLABELLED Ulcerative colitis (UC) is uncommon in Thailand. Few reports have been published and confirmation of the diagnosis was difficult. To make a firm diagnosis of UC in Thailand, long-term follow-up and demonstration of chronic and relapsing clinical courses should help to confirm the existence of UC in Thailand. OBJECTIVE To review the demographic data, clinical presentation and clinical courses of the diagnosed UC cases in Thailand. MATERIAL AND METHOD Diagnosed UC patients who were followed-up for longer than 3 months at the Diarrhea Clinic, Siriraj Hospital between 1988-2000 were included. RESULTS Forty cases of UC were followed-up. The duration of follow-up ranged from 3-75 months (mean 27 months). Male to female ratio was 19:21 and age of onset varied from 13-77 years (mean 37.7 years). Extents of the disease was left-sided colitis in 58 per cent, left and right-sided colitis in 8 per cent, pancolitis in 21 per cent, proctosigmoiditis in 13 per cent and ileal involvement in 8 per cent. At presentation, the disease was mild in 28 per cent, moderate in 60 per cent, severe in 13 per cent and fulminant in 2. Clinical presentations were diarrhea in 97.5 per cent, lower GI bleeding in 17.5 per cent, abdominal pain in 50 per cent, fever in 27.5 per cent, weight loss in 62.5 per cent and extraintestinal manifestations in 20 per cent. Diagnoses were made in all cases by sigmoidoscopy plus barium enema or colonoscopy and biopsies were taken in all cases. Histologic findings supported the diagnoses in 69 per cent of cases. Seventy per cent responded to sulfasalazine or 5-ASA with or without corticosteroid, but in 30 per cent, azathioprine was added for a period during the treatment. Clinical courses of the diseases were chronic intermittent with remission and relapse in 44 per cent, chronic continuous activity without remission in 27 per cent, single episode without relapse in 27 per cent and acute fulminating course in 6 per cent. One patient died from fulminant pancolitis with colonic perforation. There was no colonic cancer in our cases throughout the follow-up period. CONCLUSIONS UC is very uncommon in Thailand. Firm diagnosis of UC can be made through long-term follow-up and demonstration of chronic and relapsing clinical courses. The disease severity and extent of disease involvement was slightly different from that in Western countries. Incidence of extraintestinal manifestation was 20 per cent. Most cases responded to sulfasalazine, 5-ASA or corticosteroids.

Abstract
BACKGROUND The prevalence of perinuclear antineutrophil cytoplasmic antibodies (p-ANCA) does not significantly vary in ethnically diverse populations. The prevalence of p-ANCA is high in ulcerative colitis and primary sclerosing cholangitis. While the prevalence of ulcerative colitis in Asian populations is low, it is interesting to know the prevalence of p-ANCA in such a population. METHODS Sera from 33 cases of ulcerative colitis diagnosed during the last 10 years at the diarrhea clinic, Division of Gastroenterology, Siriraj Hospital, were prospectively compared with case controls consisting of 15 cases of diarrhea from non-inflammatory bowel diseases and 25 non-diarrheic patients. Indirect immunofluorescence assay was used to detect p-ANCA in all the sera. RESULTS Positive p-ANCA tests were found in 13 of the 33 patients with ulcerative colitis and in one of the 40 controls. Sensitivity of the test was 39.4% and the specificity was 97.5%. The one patient with positive p-ANCA in the control group was the patient with irritable bowel syndrome. Of the 13 p-ANCA-positive ulcerative colitis patients, two cases were found to have proctosigmoiditis, seven cases had left-sided colitis, and four cases had pancolitis. Perinuclear antineutrophil cytoplasmic antibodies was one of the 22 cases of first-degree relatives of ulcerative colitis patients (22 relatives from 12 index ulcerative colitis cases). There was no correlation between the positivity of p-ANCA and disease activity, and extent of the disease. CONCLUSION The prevalence of p-ANCA in Thai patients with ulcerative colitis (39.4%) is lower than that in the Western population. Although the prevalence of p-ANCA is low in the Thai population, it should serve as a useful tool in diagnosing ulcerative colitis in this part of the world where the disease is uncommon and difficult to diagnose. The negativity of p-ANCA in almost all first-degree relatives of Thai ulcerative colitis patients should be further elucidated.

Abstract
A companion study showed the existence of statistically significant changes in the value of karyometric "marker features" in the nuclei of histologically normal-appearing ectocervical epithelium adjacent to carcinomas in situ. In this second part of the study, the results obtained in patients with invasive cervical carcinomas were analyzed. Formalin-fixed, paraffin-embedded tissue sections were Feulgen stained and analyzed with a microTICAS video microphotometer. The results, demonstrated for the first time in histologic material, indicate that the marker features are clearly expressed in a majority of nuclei observed in the normal-appearing tissue adjacent to invasive lesions. This effect was statistically significant. The best marker features selected by the discriminant analysis were nuclear roundness, nuclear perimeter length, total optical density and a run length texture measure. These findings may reflect a subtle transformation of the apparently normal cervical epithelium adjacent to an invasive cervical carcinoma.

Abstract
Subtle changes in nuclear chromatin structure have been documented in the histologically normal mucosa adjacent to neoplastic lesions. To evaluate the expression of such "marker features" in tissue adjacent to squamous carcinomas in situ (CIS) of the uterine cervix, normal-appearing ectocervical tissues from five cases of CIS were compared with ectocervical tissues from control patients with squamous metaplasia. Formalin-fixed, paraffin-embedded tissue sections were Feulgen stained and analyzed with the microTICAS video microphotometer. Discriminant analysis revealed seven features that helped to distinguish nuclei from ectocervical tissue adjacent to CIS from those of control tissue. These features reflected changes in nuclear shape and chromatin distribution that were not detected by routine histopathologic analysis. The findings may reflect a subtle premalignant change in the apparently normal mucosa adjacent to a cervical neoplasm; they may also reflect the influence of the neoplasm on the adjacent mucosa.
