抄録

A 58-year-old woman was seen at the hospital because of dizziness and dyspnea, and had massive anal bleeding after admission. Prominent anemia was noted as the hemoglobin lebel was 7.3g/dl. Emergency upper and lower gastrointestinal endoscopy failed to identify the bleeding point. Anal bleeding persisted so that an emergency operation was carried out. A 4×3cm tumor showing an extraluminal growth was present in the small intestine 140cm distal from the Treitz' ligament. Partial resection of the small intestine including the tumor was carried out. The postoperative course was uneventful and the patient was discharged from the hospital. The tumor was diagnosed as gastrointestinal stromal tumor (GIST) by pathological and immunohistoligical studies.<br>It is difficult to make the qualitative diagnosis as for small intestinal lesions. Accordingly, we must keep a possibility of a small intestinal tumor in mind for gastrointestinal bleeding, explore and treat.
