A 53-year-old male presenting with a 3-month history of intermittent mild rectal bleeding was found, on double contrast barium enema, to have a large polyp on a long stalk in the sigmoid colon. Large bowel endoscopy confirmed the presence of a 2 cm pedunculated polyp which was removed using a diathermic snare, with slight bleeding following the procedure that did not require endoscopic haemostasis. Only after histologic examination was the polyp shown to be a colonic arteriovenous malformation. Endoscopically, arteriovenous malformations generally appear as flat or elevated bright red lesions. A pedunculated polypoid appearance is extremely uncommon. In this case, no gastrointestinal bleeding or polypoid recurrence was observed during the 12 months of clinical and endoscopic follow-up.
一名53岁男性，有3个月间歇性轻度直肠出血病史，在双重对比钡灌肠检查中发现乙状结肠有一个带长蒂的大息肉。大肠内镜检查证实有一个2厘米带蒂息肉，用透热圈套器将其切除，术后有轻微出血，无需内镜止血。组织学检查后才发现该息肉是结肠动静脉畸形。在内镜下，动静脉畸形通常表现为扁平或隆起的鲜红色病变。带蒂息肉样外观极为罕见。在本病例中，临床和内镜随访12个月期间未观察到胃肠道出血或息肉复发。
