Colonic Diverticulosis Is Not Linked with Adenoma Risk

Colonic diverticulosis has been associated with an increased prevalence of colorectal adenomas in some studies. Investigators have now prospectively studied 624 outpatients undergoing a first-time screening colonoscopy, before which a research assistant reminded the endoscopist to look for and record diverticulosis.

In this cohort, 35% of patients had one or more adenomas. Patients with diverticulosis, even those with ≥10 diverticula, had no increased risk for adenomas or advanced adenomas in either the proximal or the distal colon.
