About CBAR

The Canadian Biliary Atresia Registry (CBAR) is a collaboration between the Canadian Pediatric Hepatology Research Group (CPHRG) and the Canadian Association of Pediatric Surgeons (CAPS), the two well-established networks in Canada involved with the care of children with biliary atresia.

CBAR will engage all 16 tertiary pediatric surgical and hepatology university based hospital centres in Canada. Each site will have two site investigators: one gastroenterologist and one surgeon.
