    Abstract:
    AIMS: The aim of this study is to explore the optimal surgical approach for gastrointestinal stromal tumors (GISTs) of the stomach in terms of the perioperative outcomes and long-term relapse-free survival. METHODS: From January 2004 to July 2011, 156 patients who underwent either laparoscopic (LAP group, n = 68) or open surgery (OPEN group, n = 88) were included in the final analysis following the eligibility criteria. RESULTS: Clinicopathological characteristics of the selected patients were similar between the two groups. The LAP group was associated with less blood loss (50 vs. 180 ml, p < 0.001), shorter operating time (90 vs. 125 min, p < 0.001), earlier oral intake (3 vs. 5 days, p < 0.001), shorter postoperative hospital stay (8 vs. 10 days, p < 0.001), and low risk of postoperative complications (5.9 vs. 22.7%, p = 0.004) compared with the OPEN group. No significant difference was observed in 5-year relapse-free survival between the LAP and OPEN groups (94.2 vs. 94.0%, p = 0.807). The subgroup analysis of patients who underwent wedge resection showed similar results with the original comparison except that difference in complication rate between the two groups lost significance. CONCLUSIONS: Laparoscopic wedge resection for gastric GISTs ≤ 7 cm could get preferable short-term postoperative outcomes and similar long-term relapse-free survival compared with open surgery.
