BACKGROUND: Minimally invasive surgery has been widely used for hepatobiliary operations. This study aimed to determine the safety and feasibility of pure laparoscopic living donor right hepatectomy. METHODS: From November 2015 to April 2019, 300 cases of adult pure laparoscopic living donor right hepatectomy performed at Seoul National University Hospital were divided into three subgroups of periods 1-3 of 100 cases each: 1-100, 101-200, and 201-300, respectively. We retrospectively reviewed and analysed the safety and feasibility outcomes. RESULTS: The operative time (period 1: 318.9±62.2 min, period 2: 256.7±71.4 min, period 3: 227.7±57.4 min) and blood loss (period 1: 419.7±196.5 mL, period 2: 198.9±197.2 mL, period 3: 166.0±130.0 mL) gradually decreased (P<0.01). Similarly, the length of hospital stay decreased (period 1: 8.1±2.0 days, period 2: 7.3±3.1 days, period 3: 6.9±2.4 days, P<0.01). There was no requirement for intraoperative transfusions or care in the intensive care unit. The overall complication rate was 20/300 (6.7%), of which 8/300 (2.7%) were Clavien-Dindo grade III and above. Complications were not different among the three periods. In terms of anatomical variations, the incidences of multiple portal veins, multiple hepatic arteries, and multiple bile ducts were 32/300 (10.7%), 11/300 (3.7%), and 161/300 (53.7%), respectively. No differences were found among the three periods. CONCLUSIONS: Owing to the technical improvements over time, pure laparoscopic living donor hepatectomy is currently feasible and safe even for donors with anatomical variations. 2021 Annals of Translational Medicine.
