Objective: The aim of the study was to compare the short-term donor outcomes of laparoscopic left lateral sectionectomy (LLLS) for adult to child living donor liver transplantation (A-C LDLT) and laparoscopic donor nephrectomy (LDN).
Background: Although laparoscopy has become the standard approach in kidney donors, its use remains limited and controversial in LLS for A-C LDLT due to the lack of conclusive assessment of procedure-related morbidity.
Methods: From 2001 to 2014, 124 healthy donors undergoing laparoscopic LLLS for A-C LDLT at 5 tertiary referral centers in Europe, North America, and Asia, and 300 healthy donors undergoing LDN at 2 tertiary centers in Europe were retrospectively analyzed. The outcomes of LLLS were compared with those of LDN including the use of the comprehensive complication index (CCI).
Results: Although liver donors experienced significantly less overall (16.9% vs 31.7%, P = 0.002) and grade 1 to 2 (12.1% vs 24.7%, P = 0.004) complications than kidney donors, the rates of major complication (≥ grade 3) were similar between the 2 groups. In both groups, donors experiencing postoperative complications had similar CCI (19.3 vs 21.9 for liver and kidney donors, respectively, P = 0.29). After propensity score analysis allowing for matching donors on age, sex, and body mass index, the postoperative outcomes remained comparable between the 2 groups.
Conclusion: Laparoscopic LLS for A-C LDLT yields at least similar short-term donor outcomes as LDN. These results provide the first validation for a laparoscopic donor hepatectomy and suggest that the laparoscopic approach should be considered a new standard practice for retrieval of left lateral section liver grafts as it is for kidney donation.
