Background and study aim: Following acute diverticulitis, colonoscopy is advised to rule out malignancy. Commonly, the colonoscopy is postponed to avoid the potential risk of perforation. In a previous pilot, noncontrolled study, we showed that early colonoscopy is feasible in patients with acute diverticulitis. This randomized controlled trial compared early and late colonoscopy in hospitalized patients with acute diverticulitis.

Patients and methods: 154 patients diagnosed with acute diverticulitis were hospitalized between January 2004 and June 2006. Of these, 35 patients were excluded because of either free perforation or pericolic air on computed tomography (CT), and another 18 because they had undergone colonoscopy in the previous year. The remaining 101 patients were offered the possibility of participating in the study, with random allocation to either early in-hospital colonoscopy or late colonoscopy, 6 weeks later. Randomization was refused by 15 patients, and 86 were included in the study.

Results: 45 patients were randomly allocated for early colonoscopy and 41 for late colonoscopy. Three and 10 did not present for the examination, in the early and late group respectively. The cecum could not be reached in eight and three patients from the early and late groups, respectively. The colonoscopy revealed polyps in five patients, two in the early group and three in the late group. No malignancy was detected. There were no complications in either group.

Conclusions: Early colonoscopy in acute diverticulitis is feasible and safe in the absence of pericolic air on CT, and has greater compliance. However, no added value is apparent compared with the CT scan currently used.
