Recent evidence suggests routine colonoscopy after acute diverticulitis is not necessary but remains debatable. The aim of this study was to investigate the incidence of follow-up colonoscopic finding of adenoma, advanced neoplastic lesion, and adenocarcinoma after diverticulitis.A retrospective review of all cases of acute diverticulitis admitted from November 2015 to April 2018 was performed. Data collected included demographics, computed tomography (CT) findings, and findings of the follow-up colonoscopy within 12 months.A total of 368 patients were admitted for acute diverticulitis. A total of 366 patients underwent CT scan for diagnosis. Of whom, 185 patients (50.5%) had a follow-up colonoscopy; 115 (31.4%) did not have a follow-up colonoscopy, and the remaining have had a recent colonoscopy. The overall incidence of adenomas was 25.9% (n=48) and advanced colonic neoplasia 1.62% (n=3) in patients who underwent follow-up colonoscopy.The finding of advanced colonic neoplasia in follow-up colonoscopy after an acute episode of CT-proven diverticulitis is equivalent to, or less than, that of the population colorectal cancer screening program. Routine colonoscopy is not necessary unless there are other concerning symptoms/CT findings.
