Although ectopic pancreas and intussusception are not unusual conditions, intussusception caused by ectopic pancreas is extremely rare. Its presence along with a ruptured congenital mesenteric vascular band raises the possibility of an anomaly of the vitelline vascular system. We report the case of a 26-year-old man presenting with acute abdominal pain, vomiting, and diarrhea. CT scan showed a large amount of free fluid in his abdomen and an ileo-ileal intussusception. At laparotomy he was found to have hemoperitoneum with a ruptured, actively bleeding congenital band attached to the ileal mesentery, which was ligated, with ileo-ileal intussusception that was resected. Histopathology showed ectopic pancreatic tissue as the lead point for the intussusception. It was likely to be a ruptured mesodiverticular band and along with other findings suggested a constellation of anomalies of the vitello-intestinal tract.
虽然异位胰腺和肠套叠并不罕见，但由异位胰腺引起的肠套叠极为罕见。其存在加上破裂的先天性肠系膜血管带增加了脐肠系膜血管系统异常的可能性。我们报告了一例 26 岁男性，表现为急性腹痛、呕吐和腹泻。CT 扫描显示其腹部有大量游离液体和回-回肠套叠。剖腹探查时发现他有腹腔积血，并有附着在回肠系膜上的破裂、活跃出血的先天性带，该带被结扎，回-回肠套叠被切除。组织病理学显示异位胰腺组织是肠套叠的起点。这很可能是一个破裂的肠系膜中肠憩室带，并且结合其他发现提示存在一系列的脐肠管异常。
