OBJECTIVE: To evaluate the safety and efficacy of laparoscopic resection for gastrointestinal stromal tumors (GISTs) of the stomach with systematic review and meta-analysis. METHODS: The literature database before March, 2014 was extensively searched to retrieve the comparative studies of laparoscopic (LAP) and open resection (OPEN) for GISTs with a relevance of study goal. The inclusion and exclusion criteria were formulated. After a quality evaluation, the data were extracted. The Cochrane collaboration RevMan5.1 version software was used for meta-analysis. RESULTS: There are nineteen studies meeting the inclusion criteria for meta-analysis. The total sample size of these studies was 1,060 cases. The operation time was similar between the two groups [weighted mean difference (WMD) -7.20 min, 95 % confidence interval (CI) -25.65 to 11.25, P = 0.44)]. Compared to OPEN, however, LAP experienced less blood loss (WMD -54.21 ml, 95 % CI -82.65 to -25.77, P < 0.01), earlier time to flatus (WMD -1.34 days, 95 % CI -1.62 to -1.06, P < 0.01) and oral diet (WMD -1.80 days, 95 % CI -2.18 to -1.42, P < 0.01), shorter hospital stay (WMD -3.68 days, 95 % CI -4.52 to -2.85, P < 0.01) and decrease in overall complications [relative risk (RR) 0.51, 95 % CI 0.32-0.80, P < 0.01)]. In addition, the long-term follow-up result shows that there is no significant difference in the two groups of patients. CONCLUSION: Laparoscopic resection for gastric GISTs is a safe and feasible procedure with less blood loss, less overall complications and quicker recovery. The long-term survival situation of patients mainly depends on the tumor itself risk, and laparoscopic surgery will not increase the risks of tumor relapse and metastasis.
