Diverticular Bleeding

Abstract

Diverticular bleeding is the most common cause of massive painless rectal hemorrhage, accounting for 30–50% of cases. Diverticular bleedings are arterial bleedings that mostly result from a rupture of a submucosal artery at the base of the diverticula. In more than 80% of patients, diverticular hemorrhage resolves spontaneously. An active bleeding with identification of the bleeding diverticula is demonstrated. A ruptured small arterery is detected at the base of the diverticula. This article is part of an expert video encyclopedia.
