抄録

A 52-year-old man had been experiencing black stools and and admitted to hospital. On emergent endoscopy, he was found to have a 40mm submucosal tumor with hemorrhagic ulcer in the gastric antrum. The hemorrhagic points were stopped bleeding by clipping. On next day, he had been changing our hospital. We found mucosal surface was appeared from submucosal tumor in endoscopic examination. Endoscopic ultrasound fine needle aspiration (EUS-FNA) showed a high echoic mass from the third and fourth layer. Gastric lipoma had been diagnosed from tissue collection by EUS-FNA. The laparoscopic partial gastrectomy was performed. When gastric lipoma is larger than 4cm, it has high risk of bleeding. The risk of bleeding is involved with the size of the gastric lipoma. Surgery is enforced in many cases. But, in the case of small size ,the endoscopic resection is enforced.
