Urgent colonoscopy in patients with lower GI bleeding: a systematic review and meta-analysis

摘要

Background and Aims: Lower GI bleeding (LGIB) is a common cause of morbidity and mortality. Colonoscopy is indicated in all hospitalized patients with LGIB, yet the time frame for performing colonoscopy remains unclear. Prior studies of outcomes in urgent versus elective colonoscopy have yielded conflicting results and were often underpowered. Our study objective was to compare several outcomes between urgent and elective colonoscopy in patients hospitalized for LGIB.
