[Invagination in adults].

Two adult patients with intussusception were both diagnosed by colonoscopic investigation. The first patient, a woman aged 39, suffered from persisting abdominal discomfort with nausea and vomiting. Ultimately an ileo-ileocolic intussusception caused by an inflammatory fibroid polyp of the ileum was found. The other patient, a man of 79 years, complained of subacute cramping pain in the right lower abdomen. This was due to an ileocolic intussusception caused by an adenocarcinoma of the cecum. Both patients underwent an ileocecal resection; their postoperative courses were uneventful.
