A male in his 60s was hospitalized for a thorough examination of anemia. Upper and lower gastrointestinal endoscopic examinations showed no bleeding sources, and contrast-enhanced computed tomography showed no contrast media leakage into the gastrointestinal tract. Meckel's diverticulum was suspected by small bowel capsule endoscopy. Transanal small bowel single-balloon endoscopy showed that there were two exposed vessels with diverticula and hemorrhage in the ileum about 65 cm from the ileocecal valve, with eruptive hemorrhage from one of the exposed vessels and exudative hemorrhage from the other. Endoscopic hemostasis was difficult, and laparoscopic-assisted wedge resection of Meckel's diverticulum was performed. The resected specimen showed ulceration and no ectopic gastric mucosa nor ectopic pancreatic tissue. This was a rare case of multiple exposed vessels within a Meckel's diverticulum.
