目的探讨血型不合肝移植治疗肝功能衰竭的可行性和疗效。方法回顾性分析本中心包括21例血型不合在内的66例肝移植治疗肝功能衰竭的临床资料,包括终末期肝病模型(MELD)评分、生存率和主要并发症的发生率。结果血型相同组和血型不合组受体MELD评分分别为31.7±3.2和32.8±2.9,差异无统计学意义(P=0.154)。两组平均生存时间分别为(806.0±70.0)d和(720.3±118.5)d,术后3个月、1年、2年、3年生存率分别为84.2%、77.4%、67.6%、60.1%和75.6%、64.0%、58.2%、58.2%,两组累积生存率差异无统计学意义(P=0.417)。急性排斥反应发生率分别为8.9%(4/45)和19.0%(4/21),差异无统计学意义(P=0.253)。血型不合组术后感染和胆道并发症发生率分别为76.2%(16/21)和28.6%(6/21)显著高于相同组的48.9%(22/45,P=0.037)和8.9%(4/45,P=0.038)。严重感染和肾功能衰竭是血型不合肝移植术后早期主要死亡原因。结论在血型相同供肝严重短缺的情况下,ABO血型不同肝移植是治疗肝功能衰竭的有效手段。感染和。肾功能衰竭是围手术期最主要死因。合理的免疫抑制治疗、有效控制感染、加强围手术期的管理是提高血型不合肝移植成功率的关键。
Objective To evaluate the efficacy of ABO-incompatible orthotopic liver transplantation (OLT) in treatment of liver failure. Methods The clinical data of 66 cases of OLT, including 21 cases of ABO-incompatible OLT, for liver failure were retrospectively analyzed. Results The 3-month, and 1-, 2-, and 3-year survival rates of the ABO-identical group were 84. 2% , 77. 4% , 67. 6% , and 60. 1%, respectively, while those of the ABO-incompatible group were 75.6%, 64.0%, 58.2%, and 58.2%, respectively. The mean survival time of the ABO-identical group was (806.0± 70.0) d, not significantly different from that of the ABO-incompatible group (720.3 ± 118.5 d, P = 0.417). The acute rejection rate of the ABO-identical group was 8.9% , not significantly different from that of ABO-incompatible group (9. 0% , P =0.253). The biliary tract complication rate and infection rate of the ABO-incompatible group were 76.2% and 28.6% respectively, both significantly higher than those of the ABO-identical group (48.9% and 8.9% respectively, P =0. 037 and P =0. 038). The major causes of death in the ABO- incompatible group were serious infection (5/21) and renal failure (4/21). Conclusion ABO- incompatible OLT is an acceptable option to cure liver failure in emergency. Intensive perioperative supervision is essential to improve the effect of ABO-incompatible OLT.
