Preliminary research suggests that rectally administered nonsteroidal antiinflammatory drugs may reduce the incidence of pancreatitis after endoscopic retrograde cholangiopancreatography (ERCP).In this multicenter, randomized, placebo-controlled, double-blind clinical trial, we assigned patients at elevated risk for post-ERCP to receive a single dose rectal indomethacin or placebo immediately ERCP. Patients were determined be high on basis validated patient- and procedure-related factors....

Importance Pancreatic ductal adenocarcinoma (PDAC) is a deadly disease with increasing incidence. The majority of PDACs are incurable at presentation, but population-based screening not recommended. Surveillance high-risk individuals for PDAC may lead to early detection, the survival benefit unproven. Objective To compare patients surveillance-detected US national data. Design, Setting, and Participants This comparative cohort study was conducted in multiple academic medical centers...

Background: Choledocholithiasis is a major source of morbidity among patients undergoing cholecystectomy for symptomatic gallstones. There no consensus on the best approach to diagnosing bile duct stones. We compared safety, accuracy, diagnostic yield, and cost EUS- ERCP-based approaches. Methods: Sixty-four consecutive pre- post-cholecystectomy referred endoscopic retrograde cholangiopancreatography (ERCP) suspected choledocholithiasis were prospectively evaluated in blinded fashion. All...

Background: Although familial clusters of Barrett's oesophagus and oesophageal adenocarcinoma have been reported, a predisposition to these diseases has not systematically investigated. Aims: To determine whether (or oesophagogastric junctional) aggregate in families. Patients methods: A structured questionnaire eliciting details on reflux symptoms, exposure history, family history was given Caucasian case (n=58) subjects with oesophagus, adenocarcinoma, or junctional control (n=106)...

Endoscopic retrograde cholangiopancreatography (ERCP) is one of the most technically demanding and highestrisk procedures performed by gastrointestinal endoscopists. Hence, it requires significant focused training experience to maximize success safety (1, 2). ERCP has evolved from a purely diagnostic predominately therapeutic procedure (3). ancillary interventions are effective in nonsurgical management variety pancreaticobiliary disorders, commonly removal bile duct stones relief malignant...
