High hilar dissection: new technique to reduce biliary complication in living donor liver transplantation.
Biliary complications after living donor liver transplantation (LDLT) continue to be problematic. For reducing the biliary complications, the authors applied an intrahepatic Glissonian approach to the recipient hepatectomy. We called this Glissonian dissection technique at the high hilar level high hilar dissection (HHD). In this study, we introduced this HHD technique and evaluated its outcome in 31 recipients of a living donor liver transplant (LDLT). With total occlusion of hepatoduodenal ligament Glissonia pedicles were divided at the intrahepatic level at the third level of pedicles or beyond. After portal vein and hepatic artery were isolated from the hepatoduodenal ligament, unused bile ducts and bleeding were controlled with continuous suture of the hilar plate. Single duct anastomosis was performed in about 21 and dual duct anastomosis in 10 recipients. Bile leakage of the biliary anastomosis did not occur. There were 6 biliary complications in five patients; 2 bile leaks from the cut liver surface and 4 biliary strictures of which one of unknown etiology. In none of the patients with biliary complications, conversion to a hepaticojejunostomy was necessary. This new HHD technique during recipient hepatectomy may contribute to reduce the biliary complications in duct-to-duct anastomosis by allowing a tension free anastomosis and preserving adequate blood supply to the bile duct. Moreover, it facilitates multiple ductal anastomoses without difficult surgical manipulation.
