Abstract
BACKGROUND
The technical feasibility and oncological safety of laparoscopic surgery for gastric gastrointestinal stromal tumors (GISTs) larger than 5 cm has not been adequately studied. Therefore, we performed this retrospective study to investigate the clinical outcomes of gastric GIST patients treated with laparoscopic surgery compared with those who underwent open surgery.
METHODS
We retrospectively evaluated the outcomes of 48 consecutive patients who underwent gastric resection for gastric GISTs larger than 5 cm. The patients were divided into 2 groups based on the surgery performed: the laparoscopic resection group (LAPG) and the open resection group (OG). We assessed all available patient data, including baseline information, tumor characteristics, surgical outcomes, pathological results, postoperative complications, and long-term patient survival.
RESULTS
The 2 groups had similar baseline data. No differences were found in tumor size, location, mitotic count, and risk grade according to Fletcher's risk classification. The LAPG was superior to the OG in blood loss, time to first flatus, time to oral intake, and length of postoperative hospital stay. Perioperative complications, recurrence rate, and long-term survival, however, did not differ significantly between the groups. The mean operation time in the LAPG was 28 minutes longer than that in the OG.
CONCLUSIONS
In patients with primary gastric GISTs larger than 5 cm, laparoscopic resection is a technically feasible and oncologically safe surgery when performed by experienced surgeons.
