Introduction : The robotic hepatectomy has the advantages in the meticulous dissection of the liver hilum, the posterior side of the right liver and the inferior vena cava.

Methods : Based on 10-year experience of robotic liver resection, we started robotic living donor right hepatectomy in 2016. In this study, we introduced robotic living donor modified right hepatectomy using ICG fluorescence image

Results : Five ports were used. The patient was positioned supine with 15?reverse Trendelenburg position. First, the hilum was dissected and then, the right liver was mobilized. The inferior right hepatic vein, short hepatic veins and the IVC ligament were ligated. In recent cases, a hanging maneuver was not applied. The right hepatic inflow was temporary occluded using bulldog clamps and then 5 mg of ICG was injected into a peripheral vein. ICG accumulated in the left liver and ICG fluorescence image provided clear border between the left and right liver. The liver parenchyma was transected. The right bile duct was transected using ICG cholangiogram after applying a large hem-o-lok clip and reinforced using a prolene suture. After the right hepatic vein was isolated, the right graft was placed into a large plastic bag. A pfannenstiel incision was made with the peritoneum intact. The right hepatic artery and portal vein were ligated and sectioned using medium and large hem-o-lok clips. The right hepatic vein was ligated using a linear vascular TA and sectioned.

Conclusions : From our early experience, robotic living donor right hepatectomy is feasible and safe in selected donors by experienced hands.
