The effectiveness and safety of laparoscopic versus open hepatectomy for intrahepatic cholangiocarcinoma: a meta-analysis / 中华肝胆外科杂志

ABSTRACT

Objective:To compare the effectiveness and safety of laparoscopic hepatectomy (LH) versus open hepatectomy (OH) for intrahepatic cholangiocarcinoma(ICC).Methods:PubMed, Web of Science, Embase, Cochrane Library, China Biology Medicine Disc, China National Knowledge Infrastructure, Wanfang Database and VIP Database were searched from inception of these databases to May 2022 to compare LH versus OH for ICC. The duration of operation, intraoperative bleeding, proportion of patients with intraoperative blood transfusion, number of resected lymph nodes, proportion of patients with R 0 resection margin, duration of hepatic occlusion, hospital stay, incidence of postoperative complication and postoperative mortality were compared between the two groups. Meta-analysis was carried out using the Review Manager 5.1 software, and the mean difference ( MD) or odds ratio ( OR) was used as the effect index. Results:This meta-analysis included twelve articles, all of which were retrospective cohort studies, with 3 189 patients. There were 667 patients in the LH group and 2 512 in the OH group. Meta-analysis showed that when compared to the OH group, the LH group had significantly less intraoperative bleeding ( MD=-116.06, 95% CI -173.07--59.06, P<0.001), less proportion of patients receiving intraoperative blood transfusion ( OR=0.25, 95% CI 0.10-0.62, P=0.003), less number of lymph nodes removed ( MD=-101.91, 95% CI -124.78--79.03, P<0.001), less patients underwent portal occlusion ( OR=0.37, 95% CI 0.14 - 0.99, P=0.050), shorter hospital stay ( MD=-2.43, 95% CI -4.59--0.28, P=0.030) and less postoperative complications ( OR=0.41, 95% CI 0.28-0.61, P<0.001). However, the proportion of patients with R 0 margin ( OR=1.49, 95% CI 1.14-1.95, P=0.003) in the LH group was significantly higher than the OH group. There were no significant differences in operative time and postoperative mortality between the 2 groups. Conclusion:LH was more effective and safe than OH in the treatment of ICC. However, its long-term effect still needs to be verified by large randomized controlled trials.
