OBJECTIVES ERCP is the gold standard for pancreaticobiliary evaluation but is associated with complications. Less invasive diagnostic alternatives with similar capabilities may be cost-effective, particularly in situations involving low prevalence of disease. The aim of this study was to compare the performance of endoscopic ultrasound (EUS) with magnetic(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)
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 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 & 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)
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 Levofloxacin-based triple therapy has been suggested as an alternative salvage therapy to bismuth-based quadruple therapy for persistent Helicobacter pylori (H. pylori) infection. METHODS A search of PUBMED, EMBASE, EBM Review databases and abstracts from recent Digestive Disease Week, United European Gastroenterology Week, and European(More)
OBJECTIVES Despite a lack of supportive data, stool form and stool frequency are often used as clinical surrogates for gut transit in constipated patients. The aim of this study was to assess the correlation between stool characteristics (form and frequency) and gut transit in constipated and healthy adults. METHODS A post hoc analysis was performed on(More)
OBJECTIVES Linaclotide is a minimally absorbed peptide guanylate cyclase-C agonist. The objective of this trial was to determine the efficacy and safety of linaclotide treatment in patients with irritable bowel syndrome with constipation (IBS-C) over 26 weeks. METHODS This phase 3, double-blind, parallel-group, placebo-controlled trial randomized IBS-C(More)
