The peculiarities of prenatal morphogenesis of the common bile duct has been studied on 68 series of sequential histologic sections of human embryos and prefetuses and 50 cadavers of human fetuses by means of the methods of microscopy, morphometry, macroscopic and microscopic preparation. It has been established that the stage of embryonal occlusion during the 6th -8th weeks and the diverticulum-like dilatation at the beginning of the 4th month of the intrauterine development can be morphologic preconditions of the onset of congenital atresia and cysts of the common bile duct.
