A woman in her 50s who was suffering from intermittent abdominal pain was referred to our hospital. The presence of ileoileal intussusception was suspected based on a computed tomography scan. However, the abdominal pain improved by itself. A trans-anal double balloon enteroscopy revealed a tumor-like lesion covered with intestinal mucosa at 60cm proximal to the terminal ileum. Ulcer and redness were observed at the tip of the lesion. Based on these findings, the patient was diagnosed as having a recurrent ileoileal intussusception caused by an inverted Meckel's diverticulum. Elective laparoscopic surgery was scheduled. Intraoperatively, the orifice of the inverted Meckel's diverticulum was easily identified. Since a reduction of the inverted diverticulum was not possible, a partial ileal resection was performed. The histopathological findings revealed ectopic pancreatic and gastric tissue in the ulcerative part of the diverticulum. In the present case, a double balloon enteroscopy was useful for the differential diagnosis of intermittent abdominal pain. An appropriate diagnosis enabled an adequate preoperative evaluation and a less-invasive surgical treatment.
