A Case of an Emergency Operation Necessitated by Intestinal Intussusception Caused by a Heterotopic Pancreas with Multicystic Dilatations of the Duct

Abstract

A 29-year-old man visited our hospital complaining of epigastric pain. Abdominal computed tomography（CT）demonstrated intestinal intussusception caused by a cystic gastrointestinal tumor, and emergency surgery was performed. At laparotomy, an elastic-soft tumor measuring approximately 5 cm in diameter was palpable in the small bowel, about 180 cm from the Treitz ligament. Small bowel distention and edema were also observed 60 cm distal to the tumor site. The intestinal intussusception was resolved. We assumed that the tumor was at the lead point causing the intestinal intussusception. Therefore, partial resection of the small bowel segment including the tumor was performed. The resected specimen showed a 5.0×3.0×2.5 cm cystic tumor containing clear serous fluid. The pathological findings suggested that the lesion was heterotopic pancreas tissue（Heinrich type Ⅲ）. The postoperative course was uneventful, and the patient was discharged 10 days after surgery.
