Abstract:
BACKGROUND: Living related liver transplantation (LRLT) has gained acceptance as treatment modality for children with end-stage liver disease. The left lobe used in LRLT doesn't provide adequate parenchymal mass for its application to adults. We have used right lobe for LRLT in adults. Some criticism has been aroused becuase of the potential significant risk to the donors. METHODS: We analyzed the surgical risk and the stress to 20 donors in a right lobectomy for LRLT. We also analyzed anatomical points for safe harvest, and we describe techincal points based on anatomical variations. RESULTS: There were no deaths, and 6 major complications (3 bleeding, 1 perihepatic fluid collection, 1 pleural effusion, and 1 bile peritonitis after removal of the T-tube) occurred in 6 patients. Liver function was normalized within 2 weeks. There were anatomical variations in the hepatic vein, the portal vein, and the bile duct, especially the right inferior hepatic vein (55%), trifurcation of the portal vein (10%), low inserion of the right posterior bile duct into the common hepatic duct (10%), and separate insertion of the right anterior bile duct and right posterior bile duct into the hepatic duct (10%). We made a vena cava patch for the right inferior hepatic vein. In cases of the low insertion of the right posterior hepatic duct into the common hepatic duct, the cholecystectomy should be done carefully so as not to injure the right posterior hepatic duct. We ligated and divided the right posterior bile duct before dissection of the hepatic artery and the portal vein. In cases of trifurcation of the portal vein, closure of the left portal vein should be done to prevent the narrowing of the left portal vein lumen. CONCLUSIONS: Our results suggest that a right lobectomy for LRLT is safe for donors. However, anatomical variations in the bile duct, the hepatic vein, and the portal vein should be kept in mind to ensure a safe and successful operation.
