The changing face of liver transplantation for acute liver failure: Assessment of current status and implications for future practice.

The etiology and outcomes of acute liver failure (ALF) have changed since the definition of this disease entity in the 1970s. In particular, the role of emergency liver transplantation has evolved over time, with the development of prognostic scoring systems to facilitate listing of appropriate patients, and a better understanding of transplant benefit in patients with ALF. This review examines the changing etiology of ALF, transplant benefit, outcomes following transplantation, and future alternatives to emergency liver transplantation in this devastating condition.
