BACKGROUND AND AIMS: Biliary atresia (BA) is the leading cause of pediatric obstructive cholestasis and a major indication for liver transplantation in infants. Organoid models are increasingly used to investigate BA pathogenesis and therapeutic responses, but incomplete methodological and clinical reporting may limit cross-study comparison and translational interpretation. This study aimed to map the landscape of BA-related organoid research, identify major reporting gaps, and propose the Biliary Atresia Minimum Reporting Standard (BA-MRS) as a preliminary framework for improving reporting completeness.
METHODS: PubMed, Scopus, and Web of Science Core Collection were searched on March 8, 2026, in accordance with the PRISMA-ScR (Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews) and the 2024 Joanna Briggs Institute (JBI) Manual for Evidence Synthesis. Reporting completeness was assessed using a 36-item BA-MRS across six domains, scored as fully reported, partially reported, not reported, or not applicable.
RESULTS: Twenty-six studies published between 2020 and 2026 were included. Fibrosis and epithelial-mesenchymal transition were the most frequently studied themes, whereas only one study linked organoid findings to post-Kasai outcomes. BA case/model definition, ethics approval, and differentiation protocols were fully reported in all applicable studies (100%). In contrast, contamination monitoring (3.8%), core biliary function assays (34.6%), and clinical outcome linkage (26.3%) were poorly reported. Culture System and Sample Acquisition showed the lowest domain-level fully reported rates (58.1% and 63.2%, respectively).
CONCLUSIONS: BA organoid research has progressed beyond early model development, but reporting remains insufficient for robust comparison, reproducibility, and clinically meaningful interpretation. BA-MRS may serve as a preliminary framework for improving standardized reporting in future studies.
