The influence of hepatic macrovesicular steatosis to the early Prognosis of living liver donors following right hepatectomy / 中华肝胆外科杂志

ABSTRACT

Objective To invesgate the influence of mild hepatic macrovesicular steatosis to liver function recoveration and liver regeneration after right hemihepatectomy of the living liver donor.Methods The Medical record of 95 cases of living donor liver transplantation in our hospital between Oct 2008 to May 2009 were retrospectively analyzed, 15 donors were decteded have light macrovesicularsteatosis(20%～30%, 5 donors; 10%～19%, 10 donors) (group A),80donors have no hepatic steatosis(group B). Clinical date before operation and outcome after operation were compered. Results The average age, sex ratio,remmnent liver volume ratio, and with middle hepatic vein/without middle hepatic vein ratio had no significant differences between two groups(P=0. 870,P=0. 608,P=0. 928,P=0.196), but the body mass index(BMI) was significantly higher in group A than group B ( P = 0.013). After operation , the peak total bilirubin (TBIL) level and alanine aminotransferase(AST)were was significantly higher in group 1 than in group 2 (P=0. 039) ,the liver regeneration ratio had no significant difference after 15days of operation(P=0. 939). Multivariable analysis showed mild macrovesicular steatosis to be an independent risk factor for hyperbilirubinaemia (odds ratio 5.375(95%confidence interva 1.467-19. 6961); P=0. 011). Conclusions light macrovesicular steatosis is an independent risk factor for hyperbilirubinaemia. For the safe of the living liver donor, attentive evaluation should be done before operation to the living liver donors.
