Recurrent small bowel obstruction caused by a benign tumor. A report of two cases.

Two cases of primary small bowel tumors causing an acute intussusception are presented. In one case two polyps were found and in the other case a lipoma in the wall of the jejunum. In both cases there were symptoms of recurrent bowel obstruction for several months before the acute condition. Although intussusception caused by a benign tumor of the small bowel is a rare condition it should be taken into consideration in the differential diagnosis of abdominal pain of doubtful origin.
