Supplementary Material for: Handling of hilar vasculature in living donor right hepatectomy using extrahepatic Glissonean approach

Donor hepatectomy is one of the most important procedures in LDLT because it affects the safety of donors and the outcome of the recipients. We standardized a method of securing the important vessels at the hepatic hilum while advancing the dissection toward the central direction. This research introduces our technique of handling hilar vasculature in living donor hepatectomy, using the extrahepatic Glissonean approach, and discusses its efficacy. At first, after the extrahepatic right Glissonean approach, the resected hepatic artery and portal vein are secured on the same line as with the secured the glisson. The resected hepatic artery and portal vein are followed in the central direction, and the surrounding area is dissected. The dissection is continued up to the main brunch of hepatic artery and portal vein. The bile duct can be secured by subtracting the hepatic artery and portal vein from the tape that secured the Glissonean pedicle. The bile duct, hepatic artery, and the portal vein are dissected in this order, before dissecting the right hepatic vein, completing the surgery. This method of dissection approaching the extrahepatic Glisson is carried out towards the central direction suggest to acquire minimal tissue removal and to shorten operative time. This could result in adequate perfusion to the remaining liver and donor safety, taken together effective results on recipient.
