Laparoscopic pancreas-preserving duodenectomy: Minimally invasive surgery for superficial nonampullary duodenal epithelial tumors.

No consensus exists regarding the optimal treatment for superficial nonampullary duodenal epithelial tumors. Herein, we describe a laparoscopic pancreas-preserving duodenectomy for the treatment of a 30-mm adenoma located in the third portion of the duodenum. The adenoma was located on the pancreatic side, further hindering safe endoscopic resection. Via laparoscopy, the jejunum was transected first. After releasing the third portion of the duodenum from the retroperitoneal space, the jejunum was pulled to the right side of the superior mesenteric artery and separated from the pancreas. Under endoscopic guidance, the duodenum was then transected and duodenojejunostomy performed intracorporeally. Laparoscopic pancreas-preserving duodenectomy can be considered minimally invasive, achieving tumor radicality while preserving organs and causing minimal destruction to the abdominal wall. In conclusion, although technically demanding, laparoscopic pancreas-preserving duodenectomy is a valuable treatment option for superficial nonampullary duodenal epithelial tumors.
