27. Extraluminal laparoscopic wedge resection for gastric stromal tumors

Objective: To explore the feasibi lity and safety of extraluminal laparoscopic wedge resection (ELWR) surgery for gastrointestinal stromal tumors (GIST) in the stomach.
Methods: The clinical data of 31 patients of gastric GIST underwent ELWR was analyzed from July 2007 to June 2011, and patients’ clinicopathologic characteristics, operative outcomes, postoperative complications, and follow-up findings were analyzed retrospectively.
Results: ELWR was successfully performed for all 31 patients without open conversion. Among all 31 cases, 22 tumors were at the bottom of the stomach, and 9 at the front, with mean diameter of (3.3±1.5) cm (range, 1.5 to 5 cm). The mean operation time of ELWR was (54.1±6.2) min (range, 45 to 65 min), with the mean intraoperative blood loss of (35.2±10.5) mL (range, 15-55 mL), the mean recovery time of 1.5±0.2) d (range, 3 to 6 d) and the mean postoperative hospital stay was (4.5±1.0) d (range, 1.2-1.9 d). No patient experienced complications postoperatively. The entire cohort were followed up for 4 to 48 months (mean time 18.8 months), without recurrence or metastasis.
Conclusions: ELWR for gastric GIST is technically feasible and safe.
