婴幼儿活体肝移植33例

目的 探讨活体肝移植治疗婴幼儿终末期肝病的疗效.方法 回顾性分析2006年10月至2009年9月上海交通大学医学院附属仁济医院33例实施活体肝移植的婴幼儿的临床资料.本组患儿中位年龄10.9个月,平均体质量8.2 kg,供肝均采用肝左外叶.术后采用他克莫司或环孢素A+激素二联方案或在此基础上再加用吗替麦考酚酯的三联方案行免疫抑制治疗.分析评价手术方法、围手术期处理和随访结果.结果 供者和受者手术时间、术中出血量、术中输血量分别为(384±108)min、(183±35)ml、0和(500±103)min、(296±163)ml、(292±159)ml,供肝冷缺血时间为(64±23)min,移植物质量为(249±52)g,移植物质量与受者体质量比为2.1%±0.4%.全部供者均顺利康复,无手术并发症.受者出现肝动脉栓塞3例,门静脉栓塞2例,各类胆道并发症9例,感染11例,急性排斥反应2例,围手术期死亡5例.本组患儿1年累积生存率为85%(28/33).结论 婴幼儿终末期肝病可通过活体肝移植取得理想的效果.外科技术的提高、围手术期管理经验的积累和规范的随访可提高手术成功率和长期生存率.

Abstract：

Objective To evaluate the efficacy of living donor liver transplantation in the treatment of infants with end-stage liver diseases. Methods The clinical data of 33 infants who received living donor liver transplantation at the Renji Hospital of Shanghai Jiaotong University from October 2006 to September 2009 were retrospectively analyzed. The median age of the infants was 10.9 months, and the mean body weight was 8.2 kg.All of the grafts were left lateral lobes. Tacrolimus (or cyclosporine A) + steroid or tacrolimus (or cyclosporine A)+ steroid + mycophenolate mofeti] were applied to the infants to suppress the immune reaction. Operative techniques, perioperative management and results of follow-up were analyzed. Results The mean operation time,blood loss and blood transfusion of the donors were (384±108)minutes, (183±35) ml and O, and the three indexes of the recipients were (500± 103) minutes, (296±163) ml and (292 ± 159) ml , respectively. The cold preservation time of the grafts was (64 ±23)minutes, the mean weight of the grafts was (249 ±52)g, and the mean graft to recipient weight ratio was 2.1% ± 0.4%. All donors recovered smoothly and no complication occurred. Of the recipients, three were complicated with hepatic artery thrombosis, two with portal vein thrombosis,nine with biliary complications, 11 with infection, two with acute rejection and five infants died perioperatively.The one-year cumulative survival rate of the infants was 85% (28/33). Conclusions Infants with end-stage liver diseases could be treated by living donor liver transplantation. The development of surgical techniques and perioperative managements improves the success rate of operation and the long-term survival rate.
