Laparoscopic left lateral section procurement in living liver donors: A single center propensity score-matched study

Background: Laparoscopic living donor liver procurement for transplantation has increased in popularity over the past decade. The purpose of this study was to compare the laparoscopic and open approaches in living donor left lateral sectionectomy (LLS) and to assess the safety and feasibility of this laparoscopic approach. Methods: A total of 103 living donor LLSs were performed at our center from May 2016 to December 2017. Of these, 35 were completely laparoscopic procedures, which represented the subject of this study. An additional 68 open living donor LLSs performed during the same period were studied as a comparison group. To overcome selection bias, LLS donors were balanced on a 1:1 ratio (laparoscopic [n = 35]: open [n = 35]) according to covariates with similar values. The PSM was based on the operation date, recipient age, diagnosis, recipient weight, and donor age. Results: There were significant differences between the laparoscopic and open LLS groups (P < 0.001) in terms of blood loss (96.8 +/- 16.5 vs 155.8 +/- 17.8 mL) as well as the duration of hospital stay (4 +/- 0.4 vs 6.9 +/- 0.5 days). Conclusion: Laparoscopic LLS is a feasible and efficacious in the setting of a developed program with advanced laparoscopic expertise.
