Abstract
Objective: To evaluate the effect and safety of laparoscopic cholecystectomy (LC) on the treatment of patients with gallbladder cancer (GBC), compared with patients undergoing open cholecystectomy (OC). Methods: PubMed, EMBASE, Web of Science, CNKI, CQVIP and WANFANG DATA and the Cochrane Library were searched for all Chinese and English literatures of randomized or non-randomized concurrent controlled trials of OC and LC treatment of GBC from the database establishment to March 2020. Two reviewers selected the studies according to inclusion and exclusion criteria, extracted the data, and then a meta-analysis was subsequently performed by the RevMan 5.3 software provided by the Cochrane Library. Results: A total of 15 studies (1 074 patients) including 14 retrospective studies and 1 prospective study met the inclusion criteria. The meta-analysis showed that compared with OC, LC has significant short-term efficacy in the treatment of patients with gallbladder cancer, including shorter operation time (mean difference (MD) =-18.78, 95% confidence interval (CI) : -36.68-0.88; P=0.04), less intraoperative blood loss (MD=-166.57, 95%CI: -248.51--84.63; P<0.000 1), shorter post-operative hospital stays (MD=-5.00, 95%CI: -6.43--3.57; P<0.000 1), less complication rate (OR=0.47, 95%CI: 0.28-0.79; P=0.004), but there was no significant difference on the aspects of recurrence rate (OR=0.48, 95%CI: 0.21-1.11; P=0.09), 5-year overall survival (HR=0.93, 95%CI: 0.54-1.61, I2=33.5%, P=0.198) and long-term survival. Conclusion: Whether it is radical cholecystectomy (RC) or simple cholecystectomy (SC), the short-term efficacy of LC is more significant than that of OC, and the long-term survival rate has no significant statistical difference. Limited by the quality of literature and experiments, the above conclusions still need to be supported by higher quality research.
