The etiology of congenital biliary dilatation (CBD) is still unclear. Currently, abnormal pancreatico-bile duct confluence is the mainstream theory. In terms of classification, Todani classification is the most widely used. On the other hand, Dong's classification which proposed by Dong Jiahong and his colleagues has guiding significance for the selection of surgical methods. CBD is difficult to detect and diagnose because of the poor specificity of clinical symptoms, and it is often necessary to make a preliminary diagnosis based on the medical history, and it is also quite dependent on the assistance of imaging.
