Intussusception occurs when a proximal segment of intestine invaginates into a distal segment. It is a common cause of intestinal obstruction in children but is infrequent in adults. A 77-year-old woman presented with a 1-month history of intermittent abdominal pain associated with nausea and distended abdomen. Imaging showed a complex elongated sausage-shaped mass in the transverse colon with no obstructive pattern or free air. Surgery confirmed colonic intussusception in addition to a palpable cecal mass requiring a right hemicolectomy. Histologic study demonstrated adenocarcinoma in situ within a tubulovillous adenoma. Surgical excision of the affected intestine is the recommended treatment of choice.
肠套叠是指一段近端肠管套入远端肠管。它是儿童肠梗阻的常见原因，但在成人中并不常见。一名77岁女性，有1个月间歇性腹痛病史，伴有恶心和腹部膨隆。影像学检查显示横结肠有一个复杂的细长腊肠样肿物，无梗阻征象或游离气体。手术证实为结肠套叠，此外还发现一个可触及的盲肠肿物，需要行右半结肠切除术。组织学研究显示在管状绒毛状腺瘤内有原位腺癌。推荐的治疗选择是手术切除受累肠段。
