Abstract: Abstract： It is generally accepted that Kasai operation is the best treatment for biliary atresia (BA). The implementation of early screen plan improves the age threshold at the suitable time point of Kasai operation. This is the key issue to improve the survival rate of autologous liver in biliary atresia. The monitoring of stool color card, B- ultrasonography and serum con? jugated bilirubin can be used for preliminary seeming biliary atresia. It is very important to improve the ability of basic unit medical staff for major improvements to the understanding of the significance of biliary atresia. In some country and district, the local government has put the screen list for BA into healthcare booklet for children. Thus, it has a significant impact of early screen plan on the diagnosis and treatment of BA, and it can improve the BA autologous liver survival time. So far, there is still no BA early screen plan in the nationwide. We should pay attention to BA, and establish early screen system in different local health unit quickly.
