A 61-year-old woman developed vomiting and anorexia during hospitalization for schizophrenia. Abdominal CT found an intestinal intussusception. Ultrasonic endoscopy revealed a protuberant lesion had developed fully around the jejunum near the Treitz ligament. On gastrointestinal contrast imaging, there was circumferential narrowing in the same area. We diagnosed an intussusception by a jejunal tumor and performed laparoscopic surgery on a standby basis. The tumor appeared at 15 cm from the Treitz ligament, and about 5 cm more was found on the anal side. Laparoscopic partial resection of the small intestine was performed. The tumor comprised small intestinal villous adenomas, which were mostly highly heteromorphic. Among them, a well-differentiated adenocarcinoma with striking structural heteromorphism was observed, but there was no invasion of the submucosa and vessels. An intussusception in adults is regarded as a relatively rare disease, among which intestinal stenosis due to small intestinal villous adenomas is rarely reported. We report herein on our case with a review of the relevant literature.
