Liver transplantation for alcoholic liver disease

Abstract

The role of liver transplantation as a treatment for end-stage liver disease occurring in alcoholic patients is controversial. Earlier predictions that survival of alcoholic patients after liver transplantation was worse than that of non-alcoholic liver graft recipients, or that few alcoholic patients with serious liver disease could meet stringent selection criteria, have proved false. As a result, in many liver transplant programmes, alcoholic liver disease constitutes one of the most common diagnoses among patients proceeding to transplantation. Survival of alcoholic patients after transplantation is similar to that in non-alcoholic patients, i.e. up to 80% or more alive at 1 year. A multidisciplinary selection process has been introduced which includes careful psychiatric assessment to try to identify those patients most likely to maintain long-term abstinence after transplantation. Using this method, approximately 45% of alcoholic patients referred for transplantation have been selected for surgery. Furthermore, the survival rate of alcoholic patients not selected for transplantation because they were considered a poor prognostic risk for sobriety was significantly less than that of alcoholic patients undergoing liver transplantation. The ethical foundations for this multidisciplinary approach are explained in this chapter. Good data on recidivism after transplantation are few. In many programmes, including ours, instances of recidivism, defined as a relapse to a pathologic pattern of alcohol use, are uncommon and occur in 10% or less of alcoholic patients selected for liver transplantation, at least in the first 3 postoperative years. This figure underestimates the incidence of consumption of small amounts of alcohol. The data are limited also by the relatively short period of follow-up in most studies published to date. Whether recidivism will become more common as more patients are followed beyond 3 years remains to be seen.
