Extended donor criteria have no negative impact on early outcome after liver transplantation: a single-center multivariate analysis.

The organ shortage has driven many transplant centers to accept extended donor criteria and to modify graft allocation policies. This study was designed to analyze the impact of applying extended donor criteria (EDC) in orthotopic liver transplantation (OLT). Between December 2001 and December 2004, we performed 165 primary cadaveric whole OLTs. Up to three EDC, that is, ventilation >7 days; aminotransferases (ALT or AST) >3 x normal; bilirubin >3 mg/dL; anti-HBc or HBs Ag positivity; donor age >65 years; liver steatosis >40%; donor body mass index >30; cold ischemia time >14 hours; peak serum Na(+) >165 mmol/L; history of extrahepatic malignancy; or previous drug abuse were present in 55% of all grafts. Both univariate and multivariate analysis revealed that EDC status had no effect on graft or patient survival, the necessity for retransplantation, the length of intensive care/intermediate care unit stay, mechanical ventilation, complications, or posttransplant laboratory findings. Recipient age of >/=55 years was the only independent prognostic factor for survival, regardless of EDC. These findings suggested that the use of grafts from EDC donors are safe and expand the donor pool.
