Laparoscopic segmental duodenectomy for a gastrointestinal stromal tumor located in the second portion of the duodenum: A case report

Abstract

Gastrointestinal stromal tumors of the duodenum are rare. For benign tumors, premalignant lesions, or malignant potential tumors located in the second portion of the duodenum close to the papilla of Vater, pancreaticoduodenectomy is sometimes performed. A case of laparoscopic segmental duodenectomy for a gastrointestinal stromal tumor at the second portion of the duodenum is reported. The surgical procedure was performed as follows: first, the second portion of the duodenum was separated from the pancreatic head; second, the duodenum was cut off with the linear stapler after having confirmed preservation of the papilla by intraoperative endoscopy; and third, reconstruction was carried out by a side-to-side duodenojejunostomy. Laparoscopic segmental duodenectomy for duodenal gastrointestinal stromal tumors is thought to be advantageous compared with pancreaticoduodenectomy in terms of low burden and organ function preservation. The present procedure is feasible for benign or low-malignant tumors that do not infiltrate outside of the duodenal walls.
