A 77-year-old woman was admitted to our hospital due to abnormality of barium examination. Upper endoscopy revealed that submucosal tumor was located in the anterior wall of duodenal bulb. Histologic diagnosis was neuroendocrine tumor(NET G1). Initially, we tried to perform endoscopic submucosal resection of the lesion. But this technic was difficult because of non-lifting of the lesion after submucosal injection. Thus, we tried surgical resection of the tumor. It is difficult to recognize the border of the lesion from outside the duodenum and to remove it locally. We considered that laparoscopy-endoscopy cooperative surgery(LECS) was the best treatment for the resection of this tumor to avoid excessive resection of the duodenal wall. We located the NET by endoscopy and mucous layer was cut around the tumor. The tumor was resected manually with ultrasonic coagulating shears and the defect on the duodenal wall was repaired with manual running suture under laparoscopic surgery. The patient was discharged on 7 postoperative day without any eventful postoperative course. LECS is feasible for the treatment of duodenal NET. We report our experience of successful laparoscopic surgery for duodenal NET.
