Abstract:
Objective:To explore the influence of fatty liver donor on the prognosis of benign liver disease liver transplantation.Methods:The clinical data of 229 recipients and donors who underwent liver transplantation at Beijing Chaoyang Hospital affiliated to Capital Medical University from January 2015 to December 2019 due to benign liver diseases were retrospectively analyzed. According to the degree of fatty degeneration of the donor liver, the patients were divided into non-fatty liver group( n=168), mild-medium fatty liver group( n=43), and severe fatty liver group( n=18). First, the overall prognosis after liver transplantation was analyzed, the general data of the donor and recipient were compared, and the perioperative complications of the three groups were compared. Finally, survival analysis was performed to compare the long-term prognosis of the three groups. Measurement data with the normal distribution were represented as ( Mean± SD), comparisons among groups were analyzed using t test. Comparisons of counting data between groups were analyzed using chi-square test. The theoretical frequency was less than 1. Fisher exact probability method was used, and variance analysis was used for the comparison among the multiple groups. Results:The overall 1-year, 3-year, and 5-year survival rates of the patients were 86.9%, 70.7%, 70.7%, respectively, and the average survival time was 53.1 months. The general data of donors and recipients were not significantly different among the three groups. The probability of perioperative transplanted liver failure, delayed liver function recovery, and acute kidney injury in recipients with severe fatty liver was significantly higher than that of mild to moderate fatty liver group and non-fatty liver group ( P<0.05). The results of survival analysis showed that the 1-year, 3-year, and 5-year survival rates of the non-fatty liver group were 90.5%, 71.7%, 71.7%, the mild-moderate group were 88.4%, 76.7%, 64.0% and the severe fatty liver group were 61.1%, 49.4%, 49.4%, the survival rate of patients with severe fatty liver was significantly lower than that of the other two groups ( P<0.05). Conclusion:Donor weight-grade steatosis leads to a higher incidence of transplanted liver failure, delayed liver function recovery, acute kidney injury, and worse long-term prognosis.
