活体右半肝供体的安全性

目的 探讨活体右半肝供体的安全性。方法 对2002年1月至2005年6月施行的13例活体右半肝移植中供体的资料进行回顾性研究。不阻断入肝血流,在肝中静脉右侧,用超声刀离断肝组织得到右半供肝。通过计算得到标准肝体积及残余左半肝的比例。结果 右半供肝切取术平均失血490ml,平均输血440ml。围手术期平均输入人血白蛋白85g。1例供体门静脉分为3支,2例供体右后与右前胆管汇入左肝管,1例左外与左内胆管先后与右肝管汇合成肝总管,术中处理恰当,门静脉左干血流及左肝管胆汁引流保持通畅。2例供肝轻度脂肪变。术后第1天肝功能均有不同程度损害,但术后1周恢复到接近正常水平。术后并发症包括1例腹腔内出血,2例切口脂肪液化和1例乳糜漏。所有供体恢复好并回到原工作岗位。结论 只要保证左半肝血管与胆管通畅,残余肝体积在30％以上及手术对残余肝无大的损伤,右半供肝切取是安全的。

Safety of donor of right lobe graft in living donor liver transplantation

OBJECTIVE: To evaluate the safety of donors of right lobe graft. METHODS: We retrospectively studied 13 living donors of right lobe graft from January 2002 to June 2005. The right lobe grafts were obtained by transecting the liver on the right side of the middle hepatic vein. Liver transection was done by using an ultrasonic dissector without inflow vascular occlusion. The standard liver volume and the ratio of left lobe volume to the standard liver volume were calculated. RESULTS: The mean blood loss was 490 ml. The mean blood transfusion was 440 ml. In the perioperative period the mean albumin administered was 85 g. One donor had portal vein trifurcation, two had a right posterior bile duct and a right anterior bile duct draining into the left bile duct, respectively. One had bile ducts from left lateral and left internal segment and right duct draining into common hepatic duct. On postoperative day 1 the donors' liver functions were found impaired to some extent, but all the indices rapidly returned to the normal level at the end of the first week. Postoperative complications included 1 case of abdominal bleeding, 2 wound steatosis and 1 chyle leak. There was no donor mortality. All donors are well and have returned to their previous occupations. CONCLUSIONS: The donation of right lobe graft for adult living donor liver transplantation is safe provided that the patency of the remnant hepatic vasculature and bile duct is ensured, the volume of the remnant liver exceeds 30% of the total liver volume, and there is no injury to the remnant liver.
