A 67-year-old woman presented with lower abdominal pain. Abdominal ultrasound examination detected liver tumors. Then she was referred to our hospital for further examina-tions. A histological diagnosis of carcinoid tumor was made by a needle biopsy of the liver tumor. The primaly carcinoid tumor was not revealed by upper GI or colonoscopy. Small bowel follow-through examination showed a tumor in the ileum. The patient underwent double -balloon enteroscopy by transanal and transoral routes, but the enteroscopy could not reach the tumor because of adhesion or tumor invasion. A partial resection of the ileum and a liver were performed. Postoperative histopathological examination demonstrated the ileal carcinoid tumor accompanied by hepatic metastases. Because small-bowel carcinoid tumor mostly develops multicentric, preoperative double-balloon enteroscopy is useful for investigating other lesion in the small bowel as in our case. Moreover, a marking with double-balloon enteroscopy was effective to determine the extent of the small bowel resection.
