In the last four years, 551 liver transplantations have been performed at the Paul Brousse center, for a total of 840 liver transplantations performed from 1984 to 1992. Several changes have been observed in the field of liver transplantation in the past years. The field of immunosuppression was marked mainly by the advent of FK506 as a preventive treatment of rejection and as a treatment of cortico-resistant rejection. Results are still under analysis. From the surgical viewpoint, the main modification was the advent of UW solution, which extends cold ischemic time. However, our policy was to maintain the cold ischemic time at less than 12 hours. Primary indications for liver transplantations have changed with an increase in the rate of patients transplanted for cirrhosis related to hepatitis virus infection: from 24% in the period 1984-1988 to 42% in the period 1989-1992. The difference was due mainly to HCV-related cirrhosis, which increased from 8% to 20%. Alcoholic cirrhosis was a rare indication in the period 1989-1992 (3.4%); however, it was an increasing indication in the last 2 years. In order to improve the long-term results, major attention was given to the recurrence of initial liver disease. In patients transplanted for HBsAg-positive liver disease, long-term passive anti-HBs immunoprophylaxis was administered, which reduced the rate of HBV recurrence in patients without HBV replication before transplantation.(ABSTRACT TRUNCATED AT 250 WORDS)
