Clinical features and prognosis of children assessed for isolated small bowel or combined small bowel and liver transplantation

The hepatic histology and clinical status of 37 children on long-term parenteral nutrition (PN) referred for consideration of small bowel transplantation were determined, Seventy five percent of the children had splenomegaly and plasma bilirubin level of greater than 100 mu mol/L. All of 21 children who underwent liver biopsy, had increased fibrosis, but only half had established cirrhosis. Thirty-one children were considered to be in need of transplantation (combined liver and bowel transplant, 29; isolated bowel transplant, 2), but only 13 were stable enough to be placed on the transplant list. Seven out of the thirteen children waiting have died because of lack of size-matched organs, and the overall mortality rate of the 37 children was 70%. The main risk factors for death within 6 months were bilirubin level of greater than 100 mu mol/L, splenomegaly, and cirrhosis (P = .01), The natural history of PN-associated liver disease is that of progressive liver failure and death 6 to 12 months after onset of cholestasis, defined as bilirubin level of greater than 100 mu mol/L. The development of cirrhosis occurs after the onset of jaundice, so early referral may also permit some children to be offered isolated bowel transplantation, which has better outcome than combined liver and bowel transplantation.
