BackgroundAn acetominophen overdose (AOD) is the leading cause of acute liver failure (ALF) in the UK and USA. For patients who meet the King's College Hospital criteria, (mortality risk > 85%), an emergency orthotopic liver transplantation (OLT) is conventionally performed with subsequent life-long immunosuppression. A new technique was developed in 1998 for AOD-induced ALF where a subtotal hepatectomy (right hepatic trisectionectomy) and whole graft auxiliary liver transplant (WGALT) was performed with complete withdrawal of immunosupression during the first year post-operatively.ResultsDuring 1998-2010, 68 patients were listed for an emergency transplantation for AOD ALF at our institution: 28 died waiting, 16 underwent OLT and 24 a subtotal hepatectomy with WGALT. Eight OLT (50%) and 16 WGALT remain alive (67%); actuarial survival at 5 years OLT 50%, WGALT 63%, P = 0.37. All patients who had successful WGALT are off immunosuppression. Poor prognostic factors in the WGALT group included higher donor age (40.4 versus 53.9, P = 0.043), requirements for a blood transfusion (4.3 versus 7.6, P = 0.0043) and recipient weight (63.1 versus 54 kg, P = 0.036).ConclusionAlthough OLT remains standard practice for AOD-induced ALF, life-long immunosuppression is required. A favourable survival rate using a subtotal hepatectomy and WGALT has been demonstrated, and importantly, all successful patients have undergone complete immunosuppression withdrawal. This technique is advocated for patients who have acetominophen hepatotoxicity requiring liver transplantation.© 2013 International Hepato-Pancreato-Biliary Association.
