改良法快速肝肾供体联合切取的探讨

Rapid liver and kidney graft procurement:a report of 138 cases

目的探讨快速肝肾供体联合切取的可行性。方法总结 2 0 0 1年 1月至 2 0 0 3年 9月共 138例快速肝肾联合切取的技巧及评价移植后近期效果。快速切取技术采用原位腹主动脉 肠系膜上静脉灌注加下腔静脉引流 ,分离胃肠道后肝、胰、脾、肾整块切取 ,冰水浴中分离肝肾。结果肾脏的热缺血时间为 2～ 6min ,肝脏的热缺血时间为 3～ 8min ,整个手术过程约 2 0～ 30min。所有变异血管均保存完整。行肝移植 131例 ,术后 3d内血清ALT最高值平均为 (5 81± 392 )U/L ,无 1例出现原发性移植肝无功能 ;行肾移植 2 74例 ,术后急性肾小管坏死发生率为 3 3% (9/ 2 74 )。结论快速肝肾联合切取技术能同时保护供肝和供肾的质量 ,其方法简单、安全、有效 ,值得推广。

Objective To summarize the experience of rapid liver and kidney graft harvesting. Methods From Jan 2001 to Sep 2003,a quick procedure for combined liver and kidney procurement were used in 138 cases. The procedure includes in situ perfusion through aorta and superior mesenteric vein(SMV) plus drainage through inferior vena cava. Liver,pancreas,spleen and kidney were harvested en bloc. Results The warm ischemia time averaged at 2 to 6 minutes for kidneys and 3 to 8 minutes for livers. The total procurement time averaged at 20 to 30 minutes. All aberrant arteries were preserved. After transplantation there was no primary non-function in all 131 liver grafts,and the peak sALT level during the first 3 post-operative days was (581±392) U/L. Acute tubular necrosis rate was 3.3%(9/274) in renal grafts. Conclusion[WT5”BZ] This rapid procurement protects the quality of liver and kidney simultaneously. It is a simple,effective,safe and reasonably standardized procedure.
