Biliary atresia: the animal models.
Biliary atresia (BA) is a progressive fibrosing process of the neonatal biliary tree and liver, of unknown origin, and an as-yet unexplained pathologic mechanism. The crucial point is to elucidate the origin of this rare disease to change palliative surgery to etiology-related procedures. Patient-based research can only begin at the time of the Kasai procedure and does not allow retracing of the pathology back to its origin. Basic research has focused on similar diseases in the veterinary literature and started to simulate BA in animal models. Unfortunately, even after 50 years of research, no knowledge has been gained from such models, which has led to a single clinical application. This article reviews BA in the context of the animal models available and discusses whether future studies are promising or futile.
