The primary goal of evaluating patients for liver transplantation (LT) is to identify appropriate candidates and establish a pre-transplantation plan. Prospective patients must first be referred to a transplantation centre for evaluation and, if deemed suitable, for work-up, with a view to being listed for transplantation. South Africa has centres offering LT in Johannesburg and Cape Town. Typically, referred patients are evaluated by a clinician, and further evaluations and tests are performed before the patient is discussed at a multidisciplinary transplantation meeting. Initiating the referral early in the course of disease facilitates improved outcomes, by allowing earlier LT before the establishment of end-stage disease. It is also well described that patients awaiting transplantation (and their families) demonstrate better psychological adaptation when the entire spectrum of issues is approached by a multidisciplinary clinical team.1 It is not uncommon for children to exhibit behavioural problems, depression, poor social adaptation and non-compliance after transplantation, which can be moderated by early counselling after referral.

Purpose and policyOrgan availability is the rate-limiting step regarding successful transplantation and a reduction in waiting-list mortality. This is particularly applicable in centres that do not have related living donor programmes, but rely solely on deceased donor organs. Consequently, the decision-making and selection process must be transparent, and a consistent set of evidence-based criteria must be applied to determine whether selection for transplantation is appropriate.
IndicationsBorne out by our experience, approximately 50% of paediatric patients requiring LT have biliary atresia.2 However, the indications for LT fall into 5 major categories of liver disease: (i) cholestatic diseases; (ii) metabolic disorders; (iii) fulminant liver failure; (iv) auto-immune hepatitis; and (v) liver tumours.
General listing criteriaInfants and children should be listed for LT when there is evidence that hepatic decompensation has occurred, is imminent, or is inevitable based on the natural history of the disease. Clinical endpoints that determine suitability for transplantation may include one or more of the following: severe cholestasis; portal hypertension with/without variceal bleeding; multiple episodes of ascending cholangitis; failure of hepatic synthetic function; malnutrition and failure to thrive; intractable ascites; encephalopathy; unacceptably poor quality of life due to liver disease; and life-threatening complications of stable liver disease, such as hepatopulmonary syndrome.
Pre-LT assessment and work-upThe first step in evaluating a potential candidate for LT is to determine the severity and prognosis of the liver disease. A subjective clinical assessment is undertaken together with an objective assessment including comprehensive laboratory and radiological evaluations. The aim of this is to: (i) identify contra-indications that would either exclude LT, require dis...
