Abstract
Laparoscopic donor hepatectomy (LDH), accepted as a minimally invasive approach, has become increasingly popular for living donor liver transplant. However, the outcomes of LDH remain to be fully clarified when compared with open living donor hepatectomy. Thus, our meta-analysis was designed to assess the efficacy of laparoscopic in comparison with conventional open donor hepatectomy.The PubMed, Cochrane, and Embase electronic databases were searched to identify the articles concerning the comparison of the efficacy of laparoscopic versus open surgery in treatment of living donor liver transplantation updated to March, 2020. The main search terms and medical Subject Heading terms were: "living donor," "liver donor," "minimally invasive," "laparoscopic surgery," and "open surgery." After rigorous evaluation on quality, the data was extracted from eligible publications. The outcomes of interest included intraoperative and postoperative results.The inclusion criteria were met by a total of 20 studies. In all, 2001 subjects involving 633 patients who received laparoscopic surgery and 1368 patients who received open surgery were included. According to the pooled result of surgery duration, the laparoscopic surgery was associated with shorter duration of hospital stay (MD = -1.07, 95% CI -1.85 to -0.29; P = .007), less blood loss (MD = -57.57, 95% CI -65.07 to -50.07; P < .00001), and less postoperative complications (OR = 0.61, 95% CI 0.44-0.85; P = .003). And the open donor hepatectomy achieved a trend of shorter operation time (MD = 30.31, 95% CI 13.93-46.69; P = .0003) than laparoscopic group. Similar results were found in terms of ALT (P = .52) as well as the AST (P = .47) peak level between the 2 groups.LDH showed the better perioperative outcomes as compared with open donor hepatectomy. The findings revealed that LDH may be a feasible and safe procedure for the living donor liver transplantation.
