title: Isolated liver transplant and sequential small bowel transplantation for intestinal failure and related liver disease in children.
abstract: Liver dysfunction is a well-recognized complication of intestinal failure in children. Advances in total parenteral nutrition (TPN) have allowed these children to survive while their intestinal tract gradually adapts. Unfortunately TPN may lead to cholestatic liver disease particularly in the young children. Progression of liver disease is associated with a poor prognosis and is an indication for small bowel transplantation. We report our experience of orthotopic liver transplantation in four children with short gut and sequential liver and small bowel transplantation in one child. All children had TPN-related liver failure. Causes of intestinal failure included necrotising enterocolitis (n=2), gastroschisis (n=1), intestinal atresia (n=1), and megacystic, microcolon syndrome (n=1). At the time of liver transplantation the children's mean age was 10.9 months (2.5-24) and weight 6.7 kg (4.8-10.1). The mean serum bilirubin was 522 micromol/liter (299-823), aspartate transaminase 423 IU/liter (49-1024) and international normalized ratio 2.8 (2-3.9). There were two deaths both from respiratory failure secondary to adenovirus pneumonia including the child who received a sequential small bowel transplant. Three children with isolated liver grafts are alive and off TPN at 20 months (mean) follow up (range 6-35). Isolated orthotopic liver transplantation has a role in selected children with intestinal failure, particularly those with short but normally functioning gut and progressing with satisfactory intestinal adaptation but developing liver disease. Those children with TPN-related liver disease and unadapted gut or irreversible intestinal disease need combined liver and small bowel transplantation. Sequential small bowel transplantation is feasible after orthotopic liver transplantation and may provide an option for the child with terminal liver and small bowel failure.
