title: Long-term survival expectancy after liver transplantation in children.
abstract: OBJECTIVE
  The aim of this study was to assess the long-term survival rate in children who have undergone orthotopic liver transplantation (OLT) in the last 13 years.
  
  
  METHODS
  The records of 198 consecutive patients under 18 years of age who underwent 249 OLTs between 1986 and 1998 were reviewed. Actuarial patient survival rates were assessed at 1, 3, 5, and 10 years in the whole series, in the last 5 years, and in patients surviving more than 1 year. Age, weight, and indications were analyzed, as well as type and incidence of posttransplant complications. The median follow-up period was 41 months (0 to 154 months).
  
  
  RESULTS
  Biliary atresia was the most common indication (41.9%) followed by alpha-1 antitrypsin deficiency (8.1%), Alagille syndrome (7.6%), and fulminant hepatic failure (6.6%). One hundred forty-six patients (58.6%) were below 5 years, and 46 patients were (18.5%) younger than 1 year at operation. Sixty-eight patients (27.3%) weighed less than 10 kg. One hundred seventy whole organs and 70 reduced, 5 living-related donor, and 4 split-liver allografts were used. Hepatic artery thrombosis (n = 18), primary nonfunction (n = 15), and chronic rejection (n = 14) were the most common causes for allograft failure. Fourteen patients (7%) had posttransplant lymphoproliferative disorders (PTLD) at a median time of 28 months (4 to 124 months) postoperation (3 died). The 1-, 3-, 5-, and 10-year actuarial patient survival rates are 80%, 76%, 74%, and 74%, respectively; over the last 5 years it is 88% at 1 year and 82% at 3 and 5 years. For patients surviving more than 1 year, 3-, 5-, and 10-year actuarial survival rates are 95%, 93%, and 93%, respectively.
  
  
  CONCLUSIONS
  (1) Overall results of OLT improve with increasing experience. (2) Children who survive more than 1 year after OLT have an excellent prognosis, although long-term complications of immunosuppression can be expected.
