AASLD AST NASPGHAN Practice Guideline on pediatric liver transplantation: Candidate evaluation

Background and Aims: – Liver transplantation is a lifesaving, standard of care intervention for infants, children, and adolescents with liver tumors, inborn errors of metabolism, and irreversible liver disease caused by a wide spectrum of liver conditions. The American Association for the Study of Liver Diseases (AASLD) last published guidelines for the evaluation and selection of pediatric liver transplant candidates in 2014. This 2026 update aims to provide evidence-based recommendations that reflect current best practices and evolving clinical knowledge. Methods: – A multidisciplinary writing group of pediatric liver transplant experts and a medical librarian was convened by AASLD, with guidance by its Practice Guidelines Development Policy, and in collaboration with the North American Society of Pediatric Gastroenterology, Hepatology and Nutrition (NASPGHAN) and the American Society of Transplantation (AST). We conducted a systematic global literature review, formulated key clinical questions, and developed recommendations. Each recommendation was graded using the Oxford Centre for Evidence-Based Medicine framework and categorized by strength through a consensus voting process. Conclusion: – This document provides clear, evidence-based guidelines on the transplant evaluation process and journey in infants, children, and adolescents. It outlines indications, contraindications, and barriers to transplantation based on robust, relevant published data. It offers best practices for pre-transplant assessment, organ allocation, and strategies to optimize survival, while allowing flexibility for individual clinical scenarios.
