Changes in the indications for living donor liver transplantation: single-institution experience of 3,145 cases over 10 years

BACKGROUND: To understand the changing demands and recent trends in the indications for living donor liver transplantation (LDLT), the present study aimed to analyze the indications for LDLT performed in a high-volume transplantation center over 10 years. METHODS: The liver transplantation database at our institution was searched to identify patients who underwent LDLT during a 10-year period from January 2008 to December 2017. The study subjects (n=3,145) were divided into two groups: adult patients (n=3,019, 92.7%) and pediatric patients (n=126, 3.9%). RESULTS: In the adult recipients, the primary diagnoses were hepatitis B virus (HBV)-associated liver cirrhosis (n=1,898, 62.9%), alcoholic liver disease (n=482, 16.0%), hepatitis C virus-associated cirrhosis (n=203, 6.7%), acute liver failure (n=127, n=4.2%), and other diseases (n=157, 5.2%). The mean Model for End-Stage Liver Disease score was 15.6±8.8 (range, 6–40). The proportion of patients with HBV-associated liver disease gradually decreased, but the proportion of those with alcoholic liver disease increased. Hepatocellular carcinoma (HCC) was diagnosed in 1,467 patients (48.6%). The mean proportion of patients with HCC was 63.1% among those with HBV-associated liver disease. In pediatric recipients, the primary diagnoses were biliary atresia (n=51, 40.5%), liver failure of various causes (n=37, 29.4%), metabolic disease (n=22, 17.5%), hepatoblastoma (n=12, 9.5%), and infectious diseases (n=4, 3.2%). CONCLUSIONS: Our results showed that there were some significant changes in the indications of LDLT. We believe that our results may reflect the real changes in the indications of LDLT and they will be useful for predicting further changes in the future.
