A case of Gastrointestinal Stromal Tumor (GIST) in the small intestine diagnosed by preoperative endscopy

Abstract

A 68 years old woman was admitted to our hospital with chief complaint of tarry stool. She was administrated the anti coagulant for hypertension and atrial fibrillation. The gastrofiberscopy was done to examine with tarry stool on the day of hospitalization. We did not found bleeding point by the gastrofiberscopy and colonoscopy, except for a gastric ulcer scar. However we found the dark red stool when we inserted to the terminal ileum. She had tarry stool at the 4^th hospitalized day once again. We performed the small intestine fiberscopy and inserted to the jejunum. The submucousal tumor that had the ulcer with the bleeding from the visible vessel was recognized. We injected 1/10,000 epinephrine for hemostasis. We judged that the possibility of bleeding is high, and then an emergent operation was carried out. The histological examination reviewed small intestine GIST. We experienced the case of small intestine GIST that was able to find out a lesion by the small intestine fiberscopy. As long as we had reviewed in the literature, only four cases had been reported.
