We have used a formal transplant protocol to select patients with alcoholic liver disease (ALD) for transplantation. We retrospectively analyzed all the patients with ALD who were referred specifically for transplantation to our Liver Unit between 1987 and 1994. Patients were selected for liver transplantation if they had end-stage liver disease and had remained abstinent from the time they were medically advised to stop alcohol intake. Of the 180 patients referred for transplantation, 43 (none of whom were transplanted) had case records insufficiently complete for full analysis; this may bias the analysis. Of the remaining 137 patients, 39 were transplanted and 4 were awaiting transplantation at the time of analysis. Of the patients who were not accepted for transplantation, 13 died during the assessment, 7 were considered to be unlikely to survive the procedure, 29 were found to be medically unsuitable, 16 psychologically unsuitable, 7 patients refused the offer of transplantation, and an additional 19 either showed clinical improvement or were considered too well for transplantation. Special investigations, such as brain computerized tomography (CT) scan and echocardiograph, changed the clinical decision to transplant in only a small number of cases (4% and 5%, respectively). Nine of the transplanted patients died and the remaining were followed up for a median of 25 (range, 7-63) months. One year actuarial survival for the transplanted patients was 79%, for those considered too sick was 0%, for medically unsuitable patients was 44%, for psychologically unsuitable patients was 65% and for those considered too well was 94%. Only 5 of the transplanted patients (13%) reverted to drinking. The observed actuarial survival of nontransplanted patients was compared with the expected survival calculated by 'the Beclere model.' The observed actuarial survival in the nontransplanted groups was much better than anticipated from the Beclere model, which therefore, is not applicable to our patients. The proportional hazards regression analysis of our nontransplanted patients identified serum bilirubin, serum albumin, blood urea, ascites, and spontaneous bacterial peritonitis as factors significantly predictive of their probability of survival. Using a model based on these parameters, the expected survival of our transplanted patients was calculated. Although we applied the model to a different population, the observed actuarial survival in the transplanted patients was found to be better than their expected survival (P < or = .001). Our protocol was useful in selecting suitable patients with ALD for liver transplantation, which resulted in significant survival advantage with low recidivism rate.
我们采用了一种正式的移植方案来选择酒精性肝病(ALD)患者进行移植。我们回顾性分析了1987年至1994年间专门转诊至我们肝病科进行移植的所有ALD患者。如果患者患有终末期肝病且自接受医学建议停止饮酒后一直戒酒,则被选为肝移植对象。在转诊进行移植的180例患者中,43例(均未接受移植)的病例记录不够完整,无法进行全面分析;这可能会使分析产生偏差。在其余137例患者中,39例接受了移植,4例在分析时正在等待移植。在未被接受移植的患者中,13例在评估期间死亡,7例被认为手术存活可能性不大,29例被发现存在医学上的不适合因素,16例存在心理上的不适合因素,7例患者拒绝移植提议,另外19例要么病情出现临床改善,要么被认为情况太好而不适合移植。特殊检查,如脑部计算机断层扫描(CT)和超声心动图,仅在少数病例(分别为4%和5%)中改变了移植的临床决策。9例接受移植的患者死亡,其余患者的中位随访时间为25个月(范围7 - 63个月)。接受移植患者的1年精算生存率为79%,病情过重患者为0%,医学上不适合患者为44%,心理上不适合患者为65%,情况太好患者为94%。只有5例接受移植的患者(13%)恢复饮酒。将未接受移植患者的观察到的精算生存率与通过“贝克勒模型”计算出的预期生存率进行了比较。未接受移植组观察到的精算生存率远高于贝克勒模型的预期,因此该模型不适用于我们的患者。对我们未接受移植患者的比例风险回归分析确定血清胆红素、血清白蛋白、血尿素、腹水和自发性细菌性腹膜炎是其生存概率的显著预测因素。使用基于这些参数的模型,计算了我们接受移植患者的预期生存率。尽管我们将该模型应用于不同人群,但发现接受移植患者观察到的精算生存率高于其预期生存率(P≤0.001)。我们的方案有助于选择合适的ALD患者进行肝移植,这带来了显著的生存优势且复发率较低。
