BACKGROUND: The implementation of the laparoscopic and robotic approaches for major hepatectomy (LMH and RMH) was slower than that for minor hepatectomy, but has significantly increased over the past years. The role or advantages of RMH remains controversial, and we aimed to compare the peri-/postoperative outcomes of LMH versus RMH. METHODS: A systematic literature review was conducted using the MEDLINE and Cochrane Library databases according to the PRISMA guidelines (end-of-search date: March 16th, 2020). Only comparative studies (LMH vs. RMH) reporting on outcomes of interest were included. Meta-analysis was performed using the random-effects model when substantial heterogeneity was encountered; otherwise, the fixed-effects model was implemented. Quality of evidence assessment was performed using the Newcastle-Ottawa Scale. RESULTS: Seven retrospective cohort studies comparing LMH (n = 300) versus RMH (n = 225) were identified. No significant difference was observed between LMH and RMH regarding overall complications [odds ratio (OR) 1.42, 95% confidence interval (CI) 0.90-2.23; p = 0.13], severe complications (Clavien-Dindo grade ≥ 3) [risk difference (RD) 0.01, 95% CI - 0.03 to 0.05; p = 0.72], and overall mortality (RD 0.00, 95% CI - 0.02 to 0.03; p = 0.73). The two approaches were also equivalent regarding conversion to open hepatectomy (RD 0.03, 95% CI - 0.01 to 0.08; p = 0.15), margin-positive resection (OR 1.34, 95% CI 0.51-3.52; p = 0.55), and transfusion rate (RD - 0.03, 95% CI - 0.16 to 0.11; p = 0.67). No significant difference was observed for LMH versus RMH regarding blood loss [standardized mean difference (SMD) 0.27, 95% CI - 0.24 to 0.77; p = 0.30), operative time (SMD - 0.08, 95% CI - 0.51 to 0.34; p = 0.70), and length of stay (SMD 0.13, 95% CI - 0.58 to 0.84; p = 0.72). CONCLUSION: LMH and RMH have equivalent peri-/postoperative outcomes when performed in select patients and high-volume centers.
背景:腹腔镜和机器人辅助肝切除术(LMH 和 RMH)的实施速度慢于小肝切除术,但近年来显著增加。RMH 的作用或优势仍存在争议,我们旨在比较 LMH 与 RMH 的围手术期结局。
方法:根据 PRISMA 指南,使用 MEDLINE 和 Cochrane 图书馆数据库进行系统文献回顾(搜索结束日期:2020 年 3 月 16 日)。仅纳入报告感兴趣结局的比较研究(LMH 与 RMH)。当存在显著异质性时,采用随机效应模型进行荟萃分析;否则,采用固定效应模型。使用纽卡斯尔-渥太华量表评估证据质量。
结果:共确定了 7 项比较 LMH(n=300)与 RMH(n=225)的回顾性队列研究。LMH 与 RMH 之间在总体并发症[比值比(OR)1.42,95%置信区间(CI)0.90-2.23;p=0.13]、严重并发症(Clavien-Dindo 分级≥3)[风险差异(RD)0.01,95%CI-0.03 至 0.05;p=0.72]和总体死亡率(RD 0.00,95%CI-0.02 至 0.03;p=0.73)方面无显著差异。两种方法在转为开腹肝切除术[RD 0.03,95%CI-0.01 至 0.08;p=0.15]、边缘阳性切除[OR 1.34,95%CI 0.51-3.52;p=0.55]和输血率[RD-0.03,95%CI-0.16 至 0.11;p=0.67]方面也无显著差异。LMH 与 RMH 在术中出血量[标准化均数差(SMD)0.27,95%CI-0.24 至 0.77;p=0.30]、手术时间[SMD-0.08,95%CI-0.51 至 0.34;p=0.70]和住院时间[SMD 0.13,95%CI-0.58 至 0.84;p=0.72]方面也无显著差异。
结论:在选择的患者和高容量中心中,LMH 和 RMH 的围手术期结局相当。
