BACKGROUND Individual studies suggest that post-infectious irritable bowel syndrome is common, but symptoms gradually improve. AIM To review evidence for an association between intestinal infection and development of irritable bowel syndrome, assess the prognosis of post-infectious irritable bowel syndrome and explore factors that increase the risk.

BACKGROUND & AIMS Ulcerative colitis (UC) is difficult to treat, and standard therapy does not always induce remission. Fecal microbiota transplantation (FMT) is an alternative approach that induced remission in small series of patients with active UC. We investigated its safety and efficacy in a placebo-controlled randomized trial. METHODS We performed a(More)
BACKGROUND Current guidelines recommend the cessation of clopidogrel therapy 5 days and 7-10 days prior to colonoscopic polypectomy. Recent studies have advocated for continued clopidogrel as post-polypectomy bleeding (PPB) rates have been similar to those in the general population not on antithrombotic therapy. AIM To assess colonoscopic post-polypectomy(More)
BACKGROUND Abdominal pain after colonoscopy is a common, distressing symptom resulting from bowel distension by insufflated gas. CO(2), unlike air, is rapidly cleared from the colon by passive absorption. A commercially available CO(2) delivery system has only recently become available. The effects of CO(2) and air insufflation on residual bowel gas and(More)
BACKGROUND Very few randomized controlled trials (RCTs) have compared laparoscopic Nissen fundoplication (LNF) to proton pump inhibitors (PPI) medical management for patients with chronic gastroesophageal reflux disease (GERD). Larger RCTs have been relatively short in duration, and have reported mixed results regarding symptom control and effect on quality(More)
OBJECTIVES The objective of this study was to provide updated explicit and relevant consensus statements for clinicians to refer to when managing hospitalized adult patients with acute severe ulcerative colitis (UC). METHODS The Canadian Association of Gastroenterology consensus group of 23 voting participants developed a series of recommendation(More)
OBJECTIVES Acute lower gastrointestinal hemorrhage (LGIH) is a common indication for hospitalization. However, there are few published studies of related health care resource utilization. Resource utilization, length of stay (LOS) and direct medical costs were characterized in a cohort of patients admitted for nonmalignant LGIH to centres in Ontario. (More)
OBJECTIVE To estimate the effect of reference pricing (RP) of nonsteroidal anti-inflammatory drugs (NSAIDs) on drug subsidy program and beneficiary expenditures on analgesic drugs. DATA SOURCES/STUDY SETTING Monthly claims data from Pharmacare, the public drug subsidy program for seniors in British Columbia, Canada, over the period of February 1993 to(More)
BACKGROUND A randomized controlled trial (RCT) investigated patients with gastroesophageal reflux disease (GERD) who were stable and symptomatically controlled with long-term medical therapy to compare ongoing optimized medical therapy with laparoscopic Nissen fundoplication (LNF). METHODS Of the 180 patients eligible for randomization, 104 gave informed(More)
BACKGROUND The management of patients with acute nonvariceal upper gastrointestinal bleeding has evolved substantially over the past 10 years amid a paucity of published consensus guidelines. PURPOSE To provide evidence-based management recommendations that address clinically relevant issues. REVIEW AND CONSENSUS PROCESSES: A multidisciplinary consensus(More)
