Employing a consensus approach, our working team critically considered the available evidence and multinational expert criticism, revised the Rome II diagnostic criteria for the functional bowel disorders, and updated diagnosis and treatment recommendations. Diagnosis of a functional bowel disorder (FBD) requires characteristic symptoms during the last 3(More)
BACKGROUND Effective treatments for irritable bowel syndrome with constipation (IBS-C) are lacking. AIM To assess the efficacy and safety of lubiprostone in IBS-C. METHODS A combined analysis was performed among 1171 patients with a Rome II diagnosis of IBS-C in two phase-3 randomized trials of lubiprostone 8 mcg vs. placebo twice daily for 12 weeks.(More)
BACKGROUND Evidence from Europe, Asia, and North America suggests that standard three-drug regimens of a proton-pump inhibitor plus amoxicillin and clarithromycin are significantly less effective for eradication of Helicobacter pylori infection than are 5-day concomitant and 10-day sequential four-drug regimens that include a nitroimidazole. These four-drug(More)
Helicobacter pylori (H. pylori) remains a prevalent, worldwide, chronic infection. Though the prevalence of this infection appears to be decreasing in many parts of the world, H. pylori remains an important factor linked to the development of peptic ulcer disease, gastric malignanc and dyspeptic symptoms. Whether to test for H. pylori in patients with(More)
BACKGROUND Gastric emptying scintigraphy (GES) using a radio-labelled meal is used to measure gastric emptying. A nondigestible capsule, SmartPill, records luminal pH, temperature, and pressure during gastrointestinal transit providing a measure of gastric emptying time (GET). AIMS To compare gastric emptying time and GES by assessing their correlation,(More)
BACKGROUND & AIMS Colonic transit time (CTT) traditionally is assessed with radiopaque markers (ROMs), which requires radiation and is hindered by lack of standardization and compliance. We assessed regional and CTT with the SmartPill (SmartPill Corporation, Buffalo, NY), a new wireless pH and pressure recording capsule, in constipated and healthy subjects(More)
BACKGROUND Complications after endoscopic biliary sphincterotomy occur in 8% to 10% of patients when studied prospectively. It is not known whether the type of electrocautery current affects this rate. Theoretically, less edema of the ampulla after a pure cutting current sphincterotomy could decrease the risk of pancreatitis although the risk of(More)
OBJECTIVES To assess long-term safety and efficacy of alosetron in women with severe, chronic diarrhea-predominant IBS and in a subset having more frequent urgency (i.e., bowel urgency at least 10 of 14 days during screening). METHODS Randomized patients received either alosetron 1 mg (n = 351) or placebo (n = 363) twice daily during a 48-wk, double-blind(More)
BACKGROUND Irritable bowel syndrome with constipation (IBS-C) significantly decreases quality of life and the ability to perform daily living activities. AIM To demonstrate the long-term safety, tolerability and patient outcomes of lubiprostone in patients with IBS-C. METHODS This extension study enrolled 522 IBS-C patients who had completed one of two(More)
