Use of the hilar plate looping technique for bile duct dissection in living donor liver transplantation significantly reduces recipient biliary complications.

Biliary complications remain a major cause of morbidity after liver transplantation, especially in living donor liver transplantation (LDLT). Maintaining adequate blood supply to the bile duct is important for the prevention of biliary complications. The objective of this study was to analyze the effects of different techniques for bile duct anastomosis on posttransplantation biliary complications. From August 2005 to August 2008, 121 liver transplantations were performed at our center. Among the total 121 liver transplant recipients, 68 patients underwent a LDLT using a right lobe graft and were enrolled in this study. We used classic dissection for the first 38 recipients and the hilar plate looping technique for the next 30 patients. The hilar plate looping technique involves the looping of the complete hilar plate and Glissonian sheath around the hepatic duct after full dissection of the right hepatic artery and portal vein. Biliary complications were defined as bilomas or strictures that developed within 6 months after transplantation and required surgical or radiological intervention. There were no significant demographic differences between the 2 groups. The incidence of complications was 15 (39.5%) for classic dissection and 3 (18.8%) for hilar plate looping. Furthermore, there were no biliary strictures in the hilar plate looping group, and there was a significant difference in the complication rate between the 2 groups (P = .011). In conclusion, the hilar plate looping technique during LDLT significantly reduces recipient biliary complications.
