Left lateral sectionectomy for donor hepatectomy is a well-established alternative to deceased donor pediatric liver transplantation. However, very little is available on the laparoscopic approach (laparoscopic left lateral sectionectomy [L-LLS]). With the aim to assess safety, reproducibility under proctorship, and outcomes following living donor liver transplantation in children, a comparative single-center series using propensity score matching (PSM) to evaluate open left lateral sectionectomy (O-LLS) versus L-LLS was carried out in a relatively short time period in a high-volume pediatric transplant center. A retrospective, observational, single-center, PSM study was conducted on 220 consecutive living donor hepatectomies from January 2011 to April 2017. The variables considered for PSM were as follows: year of operation, recipient age, indication for transplant, recipient weight, donor sex, donor age, and donor body mass index. After matching, 72 O-LLSs were fit to be compared with 72 L-LLSs. Operative time and warm ischemia time were significantly longer in L-LLSs, whereas blood loss and overall donor complication rates were significantly lower. Postoperative day 1 and 4 pain scores were significantly less in the L-LLS group (P = 0.015 and 0.003, respectively). The length of hospital stay was significantly shorter in L-LLS (4.6 versus 4.1 days; P = 0.014). Overall donor biliary complications were 9 (12.5%) and 1 (1.4%) for O-LLS and L-LLS (P = 0.022), respectively. Vascular complications occurred in 3 (4.2%) children without graft loss in the laparoscopic group. The 1-, 3-, and 5-year overall patient survival rates were 98.5%, 90.9%, and 90.9% in the O-LLS group and in the L-LLS group 94.3%, 92.7%, and 86.8% (P = 0.28). In conclusion, L-LLS for donor hepatectomy is a safe and reproducible technique yielding better donor perioperative outcomes with respect to the conventional approach with similar recipient outcomes.
