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 ligature device without complications.
动静脉畸形是老年人下消化道出血的常见原因。其中，血管发育异常是一种在内镜检查中表现为红色、扁平浅表病变，有时略隆起的亚型。结肠血管发育异常很少表现为息肉样病变。本病例描述了一名60岁男性患有出血性大息肉样结肠血管发育异常。使用圈套结扎装置在内镜下将其切除，未出现并发症。
