Background:Over the past two decades robotic surgery has been introduced to many areas including liver surgery.Laparoscopic liver surgery is an alternative minimally invasive approach.However,moving on to the complexity of living donor hepatectomies,the advantages of robotic versus laparoscopic approach have convinced us to establish the robotic platform as a standard for living donor hepatectomy.Methods:From November 2018 to January 2022,501 fully robotic donor hepatectomies,including 177 left lateral donor lobes,112 full left lobes and 212 full right lobes were performed.Grafts were donated to 296 adult recipients and 205 pediatric recipients.Donor age,sex,body weight,body mass index(BMI),graft weight,graft to body weight ratio(GBWR),operative time,blood loss,first warm ischemic time,pain score,length of intensive care unit(ICU)stay and hospital stay,and complications were retrospectively analyzed based on a prospectively kept database.Recipients were evaluated for graft and patient survival,age,sex,BMI,body weight,model of end-stage liver disease score,blood loss,transfusions,operative time,cold ischemic time,length of hospital stay and complications.Results:There was no donor mortality.Two cases needed to be converted to open surgery.The median blood loss was 60 mL(range 20-800),median donor operative time was 6.77 h(range 2.93-11.53),median length of hospital stay was 4 days(range 2-22).Complication rate in donors classified following ClavienDindo was 6.4%(n=32)with one grade Ⅲ complication.Three-year actual recipient overall survival was 91.4%;87.5% for adult recipients and 97.1% for pediatric recipients.Three-year actual graft overall survival was 90.6%;87.5% for adult recipients and 95.1% for pediatric recipients.In-hospital mortality was 6%,9.1%(27/296)for adult recipients and 1.4%(3/205)for pediatric recipients.The recipients’morbidity was 19.8%(n=99).Twenty-eight recipients(5.6%)had biliary and 22(4.4%)vascular complications.Six(12.0%)recipients needed to be re-transplanted.Conclusions:With growing
