BACKGROUND AND STUDY AIMS Failed biliary cannulation occurs in up to 10% of patients undergoing ERCP. There is some controversy as to the safety and efficacy of using precut techniques to achieve biliary cannulation in difficult cases. To date, no randomized trial has compared the success and complication rates of precut with the rates for persistence when(More)
OBJECTIVE Many centers routinely admit patients for observation after endoscopic therapy of choledocholithiasis although this is contrary to the current mandate for cost containment. The purpose of this study was to determine the safety, success, and complication rates of outpatient therapeutic ERCP in the management of choledocholithiasis. METHODS Over a(More)
BACKGROUND "Sphincterotomy stenosis" is a recognized late complication of endoscopic biliary sphincterotomy. The narrowing is limited to the biliary orifice and can be managed simply by repeat sphincterotomy. A similar but poorly characterized post-sphincterotomy complication involves narrowing that extends from the biliary orifice for a variable distance(More)
BACKGROUND Effects of frequent nocturnal symptoms of gastro-oesophageal reflux disease (GERD-FNS) on health-related quality of life (HRQOL) and work productivity are not well documented. AIM To assess symptom severity, production loss, and HRQOL among employed adults with and without GERD-FNS. METHODS Using several validated outcome measures in a web(More)
Gastro-oesophageal reflux disease (GERD), manifesting with symptoms including heartburn and regurgitation, affects people during both daytime and nocturnal hours. Night-time GERD has been reported to have a greater impact on a patient's life than daytime GERD due to prolonged oesophageal acid exposure time per reflux episode. To further understand this(More)
PURPOSE The aim of this study was to determine if recall of informed consent is affected by the timing of obtaining informed consent before endoscopic procedures. METHODS Sixty patients scheduled for colonoscopy or esophagogastroduodenoscopy were enrolled in this prospective, randomized study. Each patient received informed consent 24 to 72 hours or(More)
BACKGROUND Colonic motility and spasm during colonoscopy may affect duration and quality of the examination as well as patient comfort during and after the procedure. Previous studies assessing the utility of antispasmodic agents in colonoscopy demonstrated conflicting results. The aim of this study was to determine the effect of sublingual hyoscyamine(More)
