Core Tip

Core tip: We performed laparoscopic and endoscopic co-operative surgery (LECS) procedures, such as full-thickness dissection for submucosal tumors and laparoscopic reinforcement after endoscopic submucosal dissection for epithelial tumors, for 13 early duodenal lesions in 12 patients, and analyzed the safety and feasibility of LECS for early non-ampullary duodenal tumors. All lesions were successfully resected en bloc. No severe postoperative complications (Clavien-Dindo classification grade III or higher) were reported in this series, but minor leakage secondary to pancreatic fistula occurred in one patient. LECS can be a safe and minimally invasive treatment option for non-ampullary early duodenal tumors.
