BACKGROUND & AIMS Inflammatory bowel diseases (IBD) are becoming more common in Asia, but epidemiologic data are lacking. The Asia-Pacific Crohn's and Colitis Epidemiology Study aimed to determine the incidence and phenotype of IBD in 8 countries across Asia and in Australia. METHODS We performed a prospective, population-based study of IBD incidence in(More)
Upper gastrointestinal bleeding (UGIB), especially peptic ulcer bleeding, remains one of the most important cause of hospitalisation and mortality world wide. In Asia, with a high prevalence of Helicobacter pylori infection, a potential difference in drug metabolism, and a difference in clinical management of UGIB due to variable socioeconomic environments,(More)
BACKGROUND & AIMS We compared the accuracy of a qualitative fecal immunochemical test (FIT) in identifying patients with proximal vs distal advanced neoplasia and evaluated whether analysis of 2 specimens performed better than analysis of 1 specimen. Distal advanced neoplasia was defined as colorectal cancer (CRC), any colorectal adenoma ≥10 mm in diameter,(More)
BACKGROUND Concurrent therapy with a proton-pump inhibitor is a standard treatment for patients receiving aspirin who are at risk for ulcer. Current U.S. guidelines also recommend clopidrogel for patients who have major gastrointestinal intolerance of aspirin. We compared clopidogrel with aspirin plus esomeprazole for the prevention of recurrent bleeding(More)
BACKGROUND AND AIMS Gastric intestinal metaplasia (IM) is generally considered to be a precancerous lesion in the gastric carcinogenesis cascade. This study identified the risk factors associated with progression of IM in a randomised control study. SUBJECTS AND METHODS A total of 587 Helicobacter pylori infected subjects were randomised to receive a one(More)
OBJECTIVE Since the publication of the first Asia Pacific Consensus on Colorectal Cancer (CRC) in 2008, there are substantial advancements in the science and experience of implementing CRC screening. The Asia Pacific Working Group aimed to provide an updated set of consensus recommendations. DESIGN Members from 14 Asian regions gathered to seek consensus(More)
BACKGROUND The need for therapeutic endoscopy in patients with upper GI hemorrhage is important in determining the risk and disposition of these patients. Pre-endoscopic risk scores may be helpful in predicting this need. OBJECTIVE To test the Blatchford and pre-endoscopic Rockall scores with the need for therapeutic endoscopy as the primary outcome. (More)
OBJECTIVE The rising incidence of inflammatory bowel disease in Asia supports the importance of environmental risk factors in disease aetiology. This prospective population-based case-control study in Asia-Pacific examined risk factors prior to patients developing IBD. DESIGN 442 incident cases (186 Crohn's disease (CD); 256 UC; 374 Asians) diagnosed(More)
OBJECTIVE To develop and validate a clinical risk score predictive of risk for colorectal advanced neoplasia for Asia. METHODS A prospective, cross-sectional and multicentre study was carried out in tertiary hospitals in 11 Asian cities. The subjects comprise 2752 asymptomatic patients undergoing screening colonoscopy. From a development set of 860(More)
BACKGROUND AND AIMS Fecal occult blood testing (FOBT), flexible sigmoidoscopy (FS), and colonoscopy are the most commonly recommended screening tests for colorectal cancer. The aim of this study was to compare the accuracy and safety of these 3 screening procedures in a general population of ethnic Chinese. METHODS Asymptomatic adults older than 50 years(More)
