The first five years' clinical experience of the Australian National Liver Transplantation Unit.
OBJECTIVE
To report the first five years' clinical experience of the Australian National Liver Transplant Unit.


METHODS
Three hundred and seventy patients were referred--292 adults (79%) and 78 children (21%). The major causes of liver failure in the adults were chronic active hepatitis (25%), primary biliary cirrhosis (12%), primary sclerosing cholangitis (12%), alcoholic cirrhosis (9%) and malignancy (9%). Ten per cent of patients were referred in fulminant hepatic failure. In children, the major causes were biliary atresia (40%) and inborn errors in metabolism (27%).


RESULTS
Two hundred and sixty-three patients (71%) were accepted for transplantation. Of 158 (43%) accepted for early transplantation, 22 (14%) died before a donor became available. Four hundred and forty-three suitable organ donors were referred. One hundred and twenty-six patients, including 32 children (25%), received 137 grafts. Three patients with renal failure due to hyperoxaluria type 1 received concurrent renal grafts. Ninety-two patients survived (73%). For all recipients, one-year survival was 75%. Two, three and four-year survivals were 69%. One to four-year survivals for adults with benign conditions were 77%, contrasting with results for those with hepatic malignancy (40% one-year survival). Children weighing more than 8 kg had good outcomes whether they received whole grafts or reduced-size grafts (83% one to five-year survival in both cases). Infants weighing less than 8 kg who received reduced adult grafts did significantly worse (37% one to-five year survival, P less than 0.05). Thirteen (87%) of 15 patients with fulminant hepatic failure who received grafts survived. Five of these patients were given ABO-incompatible grafts and two subsequently required retransplantation. All three patients with concurrent renal and hepatic grafts survived. Rehabilitation of survivors was excellent with 95% of adults and 100% of children pursuing normal activities. Only three grafts (2%) failed with primary non-function, all in infants because of graft infarction. Graft survival was significantly worse (P less than 0.01) in patients with a positive result to a direct cross match test against the donor.


CONCLUSIONS
The need for liver transplantation in Australia is approximately eight per million of population per year. More donor offers are required to prevent deaths of patients on the waiting list. Reduced-size livers are successful for children and have alleviated considerably the critical shortage of paediatric donor livers. Successful treatment by liver transplantation can now be achieved in more than 80% of patients with non-malignant liver disorders including those with fulminant hepatic failure not responding to conservative therapy.
