A 55-year-old-man presented with tarry stool and heart palpitations. The patient was diagnosed with hemorrhagic duodenal lipoma based on computer-tomography and endoscopic findings. Endoscopic ultrasonography (EUS) with X-ray fluoroscopy findings indicated that treatment with laparoscopy and endoscopy cooperative surgery for duodenal tumors (D-LECS) was possible. During surgery, the duodenum was first mobilized laparoscopically. Next, endoscopic mucosal resection (ESD) was performed and seromuscular sutures were applied to the area surrounding the ESD ulcer. This procedure was found to decrease the risk of stenosis and delay perforation. Therefore, it is important that the gastroenterologist and surgeon reach a consensus when deciding the treatment.
