PURPOSE: Routine colonic evaluation is advised after an episode of diverticulitis to exclude colorectal cancer. In the recent years, the possible relation between diverticulitis and colorectal cancer has been subject of debate. The aim of this study is to evaluate the benefit of routine colonic endoscopy after an episode of diverticulitis. METHODS: Records of all consecutive patients presenting with a radiologically confirmed episode of diverticulitis between 2007 and 2010 were retrieved from an in-hospital database. Patients who subsequently underwent colonic evaluation were included. The endoscopic detection rate of hyperplastic polyps, adenomas and advanced colonic neoplasia was assessed. Findings were categorized on the basis of the most advanced lesion identified. RESULTS: Three hundred and seven patients presented with a radiologically confirmed primary episode of diverticulitis. Two hundred and five patients underwent colonic evaluation. Hyperplastic polyps were found in15 (6.8 %), adenomas in 18 (8.8 %) and advanced neoplastic lesions in 7 (3.4 %) patients. Only two patients had a colorectal malignancy. CONCLUSION: There appears to be no benefit in performing routine colonic evaluation after an episode of diverticulitis as the incidence of colorectal cancer is almost equal to that of the general population. A more selective approach might therefore be justified. Potentially, only patients with persisting abdominal complaints after an episode of diverticulitis should be offered colonic evaluation to definitively exclude causal pathology.
