Abstract The aim of this paper is to report the authors experience in performing adult-to-adult living donor liver transplantation (LDLT) by using a modified technique in using grafts of the right lobe of the liver. From January 2002 to September 2006, 56 adult patients underwent LDLT using right lobe grafts at the West China Hospital, Sichuan University Medical School, China. All patients underwent a modified operation designed to improve the reconstruction of the right hepatic vein (RHV) and the tributariers of the middle hepatic vein (MHV) by interposing a vessel graft, and by anastomosing the hepatic arteries and bile ducts. There were no severe complications or deaths in all donors. Fifty-two (92.8%) recipients survived the operations. Among the 56 recipients, complications were seen in 15 recipients (26.8%), including hepatic vein stricture (one case), small-for-size syndrome (one case), hepatic artery thrombosis (two cases), intestinal bleeding (one case), bile leakage (two cases), left subphrenic abscess (one case), renal failure (two cases) and pulmonary infection (five cases). Within three months after transplantation, four recipients (7.14%) died due to smallfor-size syndrome (one case), renal failure (one case) and multiple organ failure (two cases). All patients underwent direct anastomoses of the RHV and the inferior vena cava (IVC), and in 23 cases, reconstruction of the right inferior hepatic vein was also done. In 24 patients, the reconstruction of the tributaries of the MHV was also done by interposing a vessel graft to provide sufficient venous outflow. Trifurcation of the portal vein was seen in nine cases. Thus, veno-plasty or separate anastomoses were performed. The graft and recipient body weight ratios (GRWR) were between 0.72% and 1.43%, and in three cases it was <0.8%. The graft weight to recipient standard liver volume ratios (GV/SLV) were between 31.86% and 71.68%, among which four cases had <40%. No small-for-size syndrome occurred. With modification of the surgical technique, especially in the reconstruction of the hepatic vein to provide sufficient venous outflow, living donor liver grafts in adults using the right lobe of the liver can become a relatively safe procedure and prevent the small-for-size syndrome .
