Yield of colonoscopy after recent CT-proven uncomplicated acute diverticulitis: a comparative cohort study

摘要

Current guidelines recommend routine follow-up colonoscopy after acute diverticulitis to confirm the diagnosis and exclude malignancy. Its value, however, has recently been questioned because of contradictory study results. Our objective was to compare the colonoscopic detection rate of advanced colonic neoplasia (ACN), comprising colorectal cancer (CRC) and advanced adenoma (AA), in patients after a CT-proven primary episode of uncomplicated acute diverticulitis with average risk participants in a primary colonoscopy CRC screening program.
