Robotic right lobe donor hepatectomy (RRLDH) is rarely performed, and data concerning its safety and efficacy are lacking. Here we compare our series of RRLDHs with a similar cohort undergoing open right lobe donor hepatectomy (ORLDH) with a propensity score-matched (PSM) analysis. Among 263 consecutive adult patients undergoing right lobe living donor hepatectomy from January 2015 until July 2019, 35 RRLDHs were matched to 70 ORLDHs. A 1:2 PSM analysis was performed to make the groups comparable for donor sex, age, and body mass index (BMI) and for recipient sex, age, BMI, Model for End-Stage Liver Disease score, and indication for transplant. Operative time was longer in RRLDHs compared with ORLDHs (504 +/- 73.5 versus 331 +/- 65.1 minutes;P < 0.001) but significantly decreased with the number of patients (P < 0.001). No conversions occurred. First warm ischemia time was longer and blood loss significantly less in RRLDHs (P = 0.001 and 0.003, respectively). Overall donor complications were similar: 2 (6%) in RRLDHs versus 12 (17%) in ORLDHs (P = 0.13). Biliary leak occurred in 1 (3%) patient receiving a robotic procedure and 2 (3%) patients receiving the conventional approach. Donors undergoing robotic surgery required less patient-controlled analgesia and had a shorter hospital stay compared with the open surgery group (P P = 0.001, respectively). No significant differences in graft anatomical data and recipient outcomes were recorded. RRLDH is feasible, safe, and reproducible, with significantly decreased blood loss and a shorter hospital stay compared with the open procedure. The first 35 patients receiving the robotic procedure showed a substantial reduction in operative time, reflecting a rapid shortening of the learning curve.
