Laparoscopic resection for gastric gastrointestinal stromal tumors (GISTs) is technically feasible, but the long-term effect remains uncertain. This study aims to compare the long-term oncologic outcomes of laparoscopic versus open resection of GISTs by larger cases based on tumor size–location-matched study.


Between 2006 and 2015, 63 consecutive patients with a primary gastric GIST undergoing laparoscopic resection were enrolled in and matched (1:1) to patients undergoing open resection by tumor size and location. Clinical and pathologic parameters and surgical outcomes associated with each surgical type were collected and compared.


The operation time, intraoperative blood loss, return of bowel function and oral intake, nasogastric tube retention time and postoperative stay were all shorter/faster in laparoscopic group than those in open group (P < 0.001). Postoperative complications were comparable except for the higher incidence of abdominal/incision pain in open group (9.52 vs 27%, P = 0.01). There was no statistical difference in recurrence rate (9.52 vs 15.87%, P = 0.29) and long-term recurrence-free survival between the two groups (P = 0.39).


The long-term oncologic outcome of laparoscopic resection of primary gastric GISTs is comparable to that of open procedure, but laparoscopic procedure has the advantage of minimal invasion and is superior in postoperative recovery.
