A 15-year-old woman was seen at the hospital because of lower abdominal pain and slight melena. Although no abnormalities were detected by abdominal CT and ultrasoundgraphy, an Is type lesion 8mm in diameter located 5cm distant from the dentate line was incidentally detected. The lesion was resected by endoscopic procedure with clip gripped method after we got their informed consent. The pathological diagnosis was rectal carcinoid, and the surgical stump was negative. She has had no local recurrence or distant metastasis as of 9 months after the endoscopoic resection.
Rectal carcinoid lacks in manifestations and the endoscopy has been usually used in many institutions recently. Under these background factors, there is a tendency for rectal carcinoid to be detected incidentally by endoscopy in every age group. If tumor diameter is less than 10mm, lymph node metastasis rate has been reported to be 4.3%. So endoscopic complete resection of the tumor would be very useful for diagnosis and curability. And it is conceivable that the clip gripped method is very useful for resection of the smooth surface type IIa lesions or Is like lesions.
