Endoscopic removal of a bleeding colonic polypoid angiodysplasia : case report

摘要

Arteriovenous malformations are common causes of lower gastrointestinal bleeding in the elderly. Among them, angiodysplasia is one subtype that appears on endoscopy as red, flat superficial lesions, and sometimes slightly elevated. Colonic angiodysplasia is very rarely seen as a polypoid lesion. The present case describes a bleeding large polypoid colonic angiodysplasia in a 60 year-old man. It was removed endoscopically using a PolyLoop~R ligature device without complications.
