摘　　要：目的 探讨影响肝移植术早期成功率的危险因素,总结在肝移植术前应用分子吸附再循环系统(MARS)治疗对术后患者早期生存率的影响。 方法 回顾性分析50例肝移植患者术前80次MARS治疗的临床资料,对有关临床指标进行排序分析;术后生存30d的28例为生存组,死亡6例为死亡组,对部分术前危险因素进行回归分析。 结果 50例患者中免除移植出院8例,移植前死亡8例,34例过渡到移植,移植后死亡6例。单次6 h MARS治疗较大幅度降低患者血清总胆红素、肌酐、尿酸、血氨、肿瘤坏死因子α(TNF α)和白细胞介素-10(IL-10)水平,同时显著改善系列器官功能衰竭评分(SOFA)(P<0.05);移植术后早期死亡与术前SOFA、肌酐、国际标准化比率(INR)、TNF α和IL-10等存在明显相关性。 结论 术前SOFA、肌酐、INR、TNF α和IL-10水平是移植后早期死亡的主要术前危险因素,术前MARS支持可以显著改善这些危险因素,有效提高移植成功率,甚至避免移植手术。Objective Orthotopic liver transplantation (OLT) is an accepted therapy for selected patients with advanced liver diseases. However, the early mortality rate after OLT remains relatively high due to the poor selection of candidates with various serious conditions. The aim of this study is to assess the value of pretransplantation artificial liver support treatment in reducing the pre-operation risk factors relating to early mortality after OLT. Methods 50 adult patients in various stages of different etiologies who underwent OLT procedures had been treated with molecular adsorbent recycling system (MARS) preoperatively. The study was designed in two parts: the first one was to evaluate the effectiveness of a single MARS therapy by using some clinical and laboratory parameters which were supposed to be therapeutical pretransplantation risk factors. The second part was to study the patients undergoing OLT by using the regression analysis on preoperation risk factors relating to early (within 30 d after OLT) mortality rate. Results Among the 50 patients, a statistically significant improvement (P < 0.05) of the biochemical parameters was observed (pretreatment vs posttreatment). 8 patients cancelled their scheduled LTXs due to significant improvements in their clinical conditions or recovery of their failing liver functions. 8 patients died and 34 patients successfully underwent LTX. The immediate outcome (within 30 postoperative days) of these 34 patients was that 28 were kept alive and 6 died. Conclusions Preoperation sequential organ failure assessment (SOFA), level of creatinine, INR, TNF α, and IL-10 are the main preoperative risk factors relating to early death after an operation. MARS treatment before a transplant operation can relieve these factors significantly, hence improve survival rate of liver transplantation or even make the transplantation unnecessary.
