[Adult-to-adult living-related donor liver transplantation: report of 2 cases].

Objective: To investigate the feasibility and safety of adult-to-adult living-related donor liver transplantation using a right lobe graft.

Methods: The clinical data of 2 cases of living-related donor liver transplantation performed between July, 2010 and November, 2010 were analyzed.

Results: Liver transplantation was performed using a right lobe graft including the middle hepatic vein in one case and a right lobe graft without the middle hepatic vein in the other. The ratio of graft volume to standard liver volume was 46.2% and 47.3% in the two cases, with GR/WR of 0.83 and 0.80, and donor residue liver of 42.1% and 39.5%, respectively. The donor operation lasted for 6.5 h and 5 h in the two cases with blood loss of about 200-250 ml without blood transfusion. The donors recovered uneventfully without any surgical complications, whose liver function was normal 7 days after the operation, and were discharged 14 days and 16 days after the surgery, respectively. The recipient operation lasted for 8 h and 7 h with blood loss of about 800-1000 ml. The right hepatic vein, hepatic artery, portal vein and bile duct reconstruction were performed by end-to-end anastomoses in the 2 recipients. Bile duct anastomosis stricture occurred in the first recipient 2 months after transplantation and was treated with percutaneous transhepatic cholangiography and drainage. The second recipient recovered smoothly without any complications. The recipients have so far survived 9 months and 5 months, respectively.

Conclusion: Adult-to-adult living-related donor liver transplantation is a safe and effective option for treatment of end-stage liver diseases in the context of cadaveric liver graft shortage.
