Key words:hemodialysis, Meckelʼs diverticulum, digestive tract hemorrhage, intestinal endscopy during surgery, surgical therapy 〈Abstract〉 A 53-year-old male on hemodialysis for 5 years, was hospitalized due to bloody stools. Colonoscopy was performed, but the source of bleeding could not be identified. Clinical observation was carried out under transfusion therapy, but as the patient continued to pass bloody stools several times. Thereafter, the patient was referred to our department for treatment. After admission, a colonoscopy, abdominal CT scan, and angiography were performed, but the site of the hemorrhage could not be identified. Transcatheter arterial embolization was not practical. Since a small intestine hemorrhage was suspected, laparotomy was performed and small intestine endoscopy was carried out during laparotomy;a diagnosis of ulcer hemorrhage from Meckelʼs diverticulum was made and partial resection of the ileum was performed. The postoperative course was uneventful and the patient was discharged on the 10 th post-operative day. In general, hemorrhage from Meckelʼs diverticulum is not rare as a cause of digestive tract hemorrhage, but there are few reports of such hemorrhage occurring in a ward dialysis patient. In dialysis patients, there is a latent tendency to hemorrhage due to various factors including the fragility
