Pediatric liver transplantation: the University of Padua experience

The objective of this study was to analyze experience on pediatric liver transplantation (LT) between June 1993 and September 2006, including split liver transplantation (SLT), living donor liver transplantation (LDLT), and auxiliary partial orthotopic liver transplantation (APOLT). Furthermore, hepatocyte transplantation (HT) had a role in one patient with metabolic disease.

From November 1990 to September 2006, 657 LTs were performed including 63 pediatric LTs (9.6%) in 57 patients (32 boys and 25 girls). Six were retransplantations (9.5%). Thirty-two patients (57%) were younger than 5 years. The types of graft included the following: 26 whole organs (41%), 32 in situ split organs (51%), 4 reduced-size organs (6%), and 1 graft from a living donor (2%). Two patients received an APOLT, 4 patients received a combined kidney-liver transplantation (CKLT), and 1 patient received HT. Of the 63 pediatric LTs, 16 were behaved to be highly urgent (25%).

Overall 1-, 3-, 5-, and 10-year patient survival rates were 82%, 82%, 78%, and 78%, respectively. Overall 1-, 3-, 5-, and 10-year graft survival rates were 76%, 76%, 72%, and 72%, respectively. In patients younger than 1 year, the 5-year survival rate was 100%. Perioperative mortality was 8.8%. Vascular complications occurred in 4 patients (6.3%). Six children required retransplantation due to primary nonfunction (PNF) in 4 cases (7%) and vascular thrombosis in 2 cases (3.5%).

Cholestatic liver disease and age younger than 1 year were the best prognostic factors for excellent survival.
