成人间活体肝移植右半肝移植物切取的临床分析

目的：探讨成人间活体肝移植供体右半肝切取的技术。方法：8例成人间活体肝移植行供体右半肝切取，供肝切取范围：右半肝5例、扩大右半肝3例。供肝保留直径0.8cm以上的副右肝静脉。右半肝切除线在中肝静脉的右侧0.5~1.0cm处，扩大右半肝切除线在中肝静脉左侧0.5~1.0cm处。行术中胆道造影，在切取过程中不阻断入肝血流。结果：供体平均手术时间为448（353~510）min。供体手术平均失血量为384 （170 ~900 ）ml。切取的移植物平均重669.4（445~900）g，其中右半肝移植物平均重667.0g，扩大右半肝移植物平均重673.3g。移植物与受体体重之比平均为1.16%（0.76%~1.50%）。供体术后发生胆漏、肝肾功能不全各1例，经治疗后均痊愈。全组无手术死亡，均于3周内恢复出院。8例移植物和8例受体的1年生存率均为100%。结论：熟练掌握精良的供肝切取技术，成人活体肝移植中右半肝和扩大右半肝的切取对供体来说是安全的。

Clinical analysis of right lobe hepatectomy in adult-to-adult living donor liver transplantations

Objective:To study the surgical technique of right hemihepatectomy in adult-to-adult living donor liver transplantation. Methods: Eight donors underwent right hemihepatectomy in adult-to-adult living donor liver transplantation. Among these donors operation, there were 5 right hemihepatectomy and 3 extended right hemihepatectomy. If the diameter of the auxiliary right hepatic vein more than 0.8cm, it should be reserved. The dissection line of right hemihepatectomy was at the 0.5cm~1.0cm to the right side of middle hepatic vein, and the dissection line of extended right hemihepatectomy was at 0.5cm~1.0cm to the left side of middle hepatic vein. Intraoperative cholangiogram was performed, and without inflow vascular occlusion was done during the operation.Results : The donor average operation time was 448 min (ranged from 353 min to 510 min). The average blood loss of operation was 384 ml (ranged from 170ml to 900ml). The grafts average weight was 669.4g (ranged from 445g to 900g), the right hemihepatic grafts weighted 667.0g averagely and the extended right hemihepatectic grafts weighted 673.3g averagely.The average graft-to-recipient body weight was 1.16% (ranged from 0.76% to 1.50%). There were 2 donors occurred complications including biliary leak in 1, and dysfunction of liver and kidney in 1, all the 2 complications were cured. There was no donor mortality and all donors well recovered,All the donors were discharged within three weeks after operation.All of the 8 grafts and 8 recipients survived one year. Conclusions:The right hemihepatectomy and extended right hemihepatectomy in adult-to-adult living donor liver transplantation can be performed safely,if the liver resection techmqne is proformed exactly and successfully.
