Overview

Liver transplantation remains the only definitive therapy in patients of acute liver failure who fail to regenerate liver tissue to maintain life. Whole organ liver transplantation (deceased liver) or living donor liver transplantation(LDLT) can also be opted.

Surgery

• Drainage of ascites
• While many people who develop acute liver failure recover with supportive treatment, liver transplantation is often required in people who continue to deteriorate or have adverse prognostic factors.
• "Liver dialysis" (various measures to replace normal liver function) is evolving as a treatment modality and is gradually being introduced in the care of patients with liver failure.

Liver Transplantation

The King's College criteria were described in a publication in 1989 by J.G. O'Grady and colleagues. The criteria were stratified into acetaminophen and non-acetaminophen causes of acute liver failure, due to the different operating characteristics of parameters correlating with prognosis in the two causes.

King's College Hospital criteria for liver transplantation in acute liver failure

Patients with paracetamol toxicity pH <7.3 or Prothrombin time >100 seconds and serum creatinine level >3.4 mg/dL (>300 μmol/l) if in grade III or IV encephalopathy

Other patients Prothrombin time >100 seconds or Three of the following variables: Age <10 yr or >40 yr Cause: non-A, non-B hepatitis halothane hepatitis idiosyncratic drug reaction Duration of jaundice before encephalopathy >7 days prothrombin time >50 seconds Serum bilirubin level >17.6 mg/dL (>300 μmol/l)

2011 AASLD Recommendations : Liver Transplantation (DO NOT EDIT)

Class I

Class II-3

1. Urgent hepatic transplantation is indicated in acute liver failure where prognostic indicators suggest a high likelihood of death.

2. Living donor or auxiliary liver transplantation may be considered in the setting of limited organ supply, but its use remains controversial.

Class III

1. Contact with a transplant center and plans to transfer appropriate patients with ALF should be initiated early in the evaluation process.

2. Patients with acute liver failure secondary to mushroom poisoning should be listed for transplantation, as this procedure is often the only lifesaving option.
