改良背驮式与经典背驮式肝移植的临床对照研究

Comparison of standard with modified piggyback liver transplantation

目的对比研究经典背驮式肝移植和改良背驮式肝移植两种术式的临床特点，探讨其优缺点。方法自2003年2月至2006年8月．对37例肝炎后肝硬化和急性重症肝炎病人施行了肝移植术，男30例，女7例；年龄18～62岁．平均41．7岁。原发病分别为：乙型肝炎后肝硬化35例，急性重症肝炎2例，乙型肝炎病毒表面抗原（HBsAg）均阳性。手术方式采用经典背驮式A组11例，改良背驮式B组26例，37例于术令郜成功。结果改良背驮式肝移植组的于术时间短，术小出血输血砖少，医疗费用少。结论改良背驮式肝移植技术具有简化手术操作，缩短手术时间，减少术后并发症，医疗费用少等优点。

Objective To discuss the effects of two different operational patterns of piggyback liver transplantation in clinical application. Methods Thirty seven patients with final hepatic diseases sequentially received the two kind of operational procedures. Piggyback OLT was performed （POLT） in 11cases and the modified POLT （MPOLT） in 26cases. Results Compared with POLT, MPOLT offered shorter operative time, needed less amount of blood and less blood transfusion and achieved sooner recovery of liver function. Conclusion MPOLT is easier to be performed and cost less.
