Laparoscopic Limited Resection for Duodenal Gastrointestinal Stromal Tumors

Laparoscopic surgery may be a suitable treatment for gastrointestinal stromal tumors (GISTs) in terms of oncological feasibility and being minimally invasive. Case series of laparoscopic resection for duodenal GISTs have not been reported in detail, so in this report, the detail of laparoscopic surgeries for duodenal GISTs is summarized.

This is a single-center retrospective case series of six consecutive patients with duodenal GISTs who underwent laparoscopic limited resection of the duodenum between 2003 and 2019.

Tumors were located within the first portion in three patients, the second portion in two patients, and the third portion in one patient. Median tumor size was 25 mm. Four patients underwent a laparoscopic and endoscopic full-thickness resection with primary closure, one patient underwent a laparoscopic wedge resection, and one patient underwent a laparoscopic segmental duodenectomy with Roux-en-Y gastrojejunostomy. Median blood loss was minimal (10 ml) with median operative time of 2 h, and there were no conversions to open surgery. There were no intraoperative or postoperative complications. All patients underwent curative resection with negative surgical margins, and none had recurrence of their duodenal GISTs. All patients were alive at the end of the follow-up period of 54 months.

Laparoscopic limited resection is a feasible, safe, and ideal treatment procedure for duodenal GISTs in terms of short- and long-term surgical outcomes.
