Giant Colonic Angiodysplasia

Abstract

Angiodysplasia is an important vascular lesion of the gut and a potential source of significant bleeding. Angiodysplasia in the large bowel occurs most often in the right colon. Patients with bleeding angiodysplasia are treated by endoscopic methods. Because the bleeding risk of incidental angiodysplasia in general is low, endoscopic treatment for nonbleeding lesions is unnecessary. The author demonstrates a case with a giant angiodysplasia in the ascending colon. This article is part of an expert video encyclopedia.
