A 23-Year Comprehensive Analysis of over 4000 Liver Transplants in Türkiye: Integrating Clinical Outcomes with Public Health Insights.

Background: This study seeks to evaluate the 23 year experience of the İnonu University Liver Transplantation Institute from a public health perspective by examining demographic patterns, etiological factors, and transplantation trends between 2002 and 2025. Aims: This analysis aims to provide insights into the epidemiological landscape of liver transplantation in Türkiye from a public health perspective. Methods: In this retrospective cross sectional study, we analyzed 4011 liver transplant procedures performed between March 2002 and March 2025. Recipient demographics, disease etiologies, donor characteristics, and patients geographic distribution were assessed to delineate regional health needs and service utilization patterns. Results: A total of 4011 patients were included. The cohort comprised 2618 males (65.3%) and 1393 females (34.7%). Recipients were classified as adult (n = 3232, 80.9%) or pediatric (n = 779, 19.1%). Among adults, infectious etiologies were the most prevalent (35.5%), followed by cryptogenic liver cirrhosis (24.7%). In contrast, pediatric patients most commonly presented with toxic etiologies (29.4%), metabolic disorders (22.6%) and bile duct diseases (15.9%). Most liver transplantations were performed using living donors (n = 3481, 86.8%), while deceased donors accounted for 530 procedures (13.2%). Additionally, 244 living donor liver transplantations were performed via liver paired exchange (LPE). Conclusions: These findings may inform resource allocation, health policy development, and the optimization of transplantation services. This center-based model offers a useful framework for characterizing regional health needs and strengthening community health, particularly through prevention, screening, and early intervention strategies for liver diseases.
