Long-term analysis of primary nonfunction in liver transplant recipients.

UNLABELLED

Long-term allograft and patient survival following liver transplantation continues to improve with the development of new surgical techniques and immunosuppressive agents. Complications such as primary nonfunction (PNF) have not been well characterized in terms of long-term allograft and patient survival. The aim of this study was to determine the incidence of PNF in liver transplant recipients and patient and graft survival, in addition to identifying temporal trends in these parameters.

METHOD

Data were obtained from the United Network for Organ Sharing/Organ Procurement and Transplant Network for all adults (>18 years old) who received a deceased donor liver transplant between January 1990 and December 2004.

RESULTS

Of the 58,576 liver transplant recipients, 2061 had PNF, an overall incidence of 3.5%. There was a 30% annual increase in the incidence of PNF between 1990 and 2000; the incidence of PNF peaked at 7%, and then decreased by 20% annually thereafter. No differences in donor and perioperative variables were identified to account for this variation. One-, 3-, and 5-year patient and graft survival for patients with PNF who underwent retransplant were significantly lower than those with primary liver transplant. In conclusion, there has been decreased incidence of PNF among liver transplant recipients in the last decade.
