Liver transplantation: need, indications, patient selection and pre-transplant care.

Chronic or acute liver failure and primary liver cancers can be effectively managed with liver transplantation. The range of indications for liver transplantation is increasing but there is a mismatch between the numbers of available donations and current needs. Specific criteria for listing patients exist but, at minimum, the predicted mortality without transplantation must exceed that with transplantation, coupled with a 50% predicted 5-year survival following liver transplantation. The risk posed by liver disease must be weighed against the risk of liver transplantation, considering the patient's comorbidities, age, nutritional status and behavioural factors in a complex assessment process. This article reviews current UK practice in the selection and care of patients being assessed for liver transplantation.
