TL;DR: Analysis of patients endoscoped for nonvariceal upper gastrointestinal bleeding at 18 community and tertiary care institutions between 1999 and 2002 appears to confirm the protective role of endoscopic therapy in patients with high-risk stigmata, and suggest that acute use of PPIs may be associated with a reduction of rebleeding in all patients, and lower mortality in patientsWith high- Risk Stigmata.

TL;DR: In this paper, the authors evaluated the overall sensitivity and specificity of Magnetic Resonance Cholangiopancreatography (MRCP) in suspected biliary obstruction and to evaluate clinically important subgroups.
