Comparative Study
The utilization of liver transplantation in the management of acute liver failure: comparison between acetaminophen and non-acetaminophen etiologies.
Liver transplantation (LT) may be life-saving in severe acute liver failure (ALF). The aim of this study was to compare the utilization of LT in acetaminophen and non-acetaminophen ALF. Between 1992 and 2006, 469 patients with ALF were admitted, and 104 underwent LT. ⋯ An analysis of cohorts admitted in 1993-1996 and 2002-2005 revealed that LT proceeded less commonly in acetaminophen ALF in the later cohort (1993-1996: 16/99 LT, 16.2%; 2002-2005: 4/81 LT, 5%; P < 0.01) in comparison with the non-acetaminophen cohort, in which transplantation proceeded more commonly in the later cohort (1993-1996: 11/34 LT, 32.4%; 2002-2005: 24/49 patients, 49.0%; P < 0.01). This was due to an increase in the number of patients with psychiatric contraindications to transplantation (predominantly resistant and severe alcohol dependence). In conclusion, at all decision steps between admission and emergency LT, LT is favored in non-acetaminophen patients, and nonoperative management is favored in acetaminophen ALF patients.
