大泡性脂肪变性对活体肝移植右半肝供者早期预后的影响

目的 研究轻度大泡性脂肪变性对活体肝移植供者右半肝切除术后早期肝功能恢复及再生的影响.方法 回顾性分析2007年10月至2009年5月间本移植外科小组完成的95例活体肝移植术(living donorlivertransplantation LDLT)供者的临床资料.术中冰冻活检发现15例存在轻度大泡性脂肪变性(20%～30%5例,10%～19%10例)(A组),80例无明显脂肪变性(B组).比较两组术前基本资料及术后临床结果.结果 单因素分析发现A、B两组术前平均年龄、性别比、残肝体积比、保留肝中静脉/不保留肝中静脉比无显著差异(P=0.870,P=0.608,P=0.928,P=0.196),但A组体重指数(BMI)显著高于B组(P=0.013).t检验发现A组术后总胆红素(TBIL)、丙氨酸氨基转移酶(ALT)峰值显著高于B组(P=0.001,P=0.039),2组术后半月的肝脏再生率无显著差异(P=0.939);Logistic多因素统计分析发现轻度大泡性脂肪变性是导致供者术后高胆红素血症的危险因素(OR=5.375,95%可信区间1.467-19.696,P=0.011).结论 轻度大泡性脂肪变性是术后高胆红素血症的独立危险因素,从供者安全性考虑,对活体肝移植供者需仔细进行术前评估.

The influence of hepatic macrovesicular steatosis to the early Prognosis of living liver donors following right hepatectomy

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.
