A 60-year-old woman who underwent mitral valve replacement experienced melena on the thirteenth postoperative day. We performed gastrofiberscopy and total colonoscopy, but the hemorrhage point was not clear. Abdominal computed tomography showed a tumor 4.0 cm in diameter in the small intestine. Abdominal angiography revealed a tumor in the ileocolic artery. We diagnosed it as an ileal tumor and performed an operation. The patient had a medical history of laparoscopic cholecystectomy, but we decided to perform partial excision of the ileum under laparoscopic assistance because of the diagnosis of a tumor. A tumor 5.0 cm in diameter was present in the terminal ileum, and we performed partial ileal resection. The pathological result was GIST. This presents with melena, and we diagnosed it as an ileal tumor by CT and angiography; we report it as an example of ileal GIST which we removed surgically under laparoscopic assistance.
