BACKGROUND: The innovative pure laparoscopic living donor right hepatectomy (LLDRH) procedure for liver transplantation has never been fully compared to open living donor right hepatectomy (OLDRH). We aimed to compare the donor safety and graft results of pure LLDRH to those of OLDRH. METHODS: From May 2013 to July 2017, 288 consecutive donors underwent either OLDRH (n = 197) or pure LLDRH (n = 91). After propensity score matching, 72 donors were included in each group. The primary outcome was postoperative complications during a 90-day follow-up period. Comprehensive complication index, duration of hospital stay, need for additional pain control, readmission, and donor outcomes were also compared. RESULTS: The incidence of major complication during the 90-day follow-up was higher in the LLDRH group than the OLDRH group (6.6% vs 15.4%, P = 0.017) but was not statistically significant in propensity-matched analysis (11.1% vs 13.9%, odds ratio [OR], 1.29; 95% confidence interval [CI], 0.47-3.51; P = 0.62). A right hepatic duct <1 cm was independently associated with complication in the pure LLDRH group (odds ratio, 4.01; 95% confidence interval, 1.08-14.99; P = 0.04). CONCLUSIONS: In the initial 91 pure LLDRH cases, incidence of major complication was higher than in the OLDRH group, but the difference was not significant in propensity-matched analysis. A right hepatic duct verified as <1 cm may be related to increased frequency of complications in pure LLDRH donors. Further analysis is needed.
