Should a colonoscopy be offered routinely to patients with CT proven acute diverticulitis? A retrospective cohort study and meta-analysis of best available evidence.

Background: The current guidelines suggest that patients should undergo endoscopic evaluation of the colonic lumen after an episode of computed tomography (CT) proven acute diverticulitis to rule out malignancy. The usefulness of routine endoscopic evaluation of CT proven diverticulitis remains unknown.

Aim: To establish whether routine colonoscopy should be offered to patients after an episode of diverticulitis.
