DYNAMICS OF MORPHOMETRIC CHANGES OF COMMON BILE DUCT IN HUMAN FETUSES AND NEWBORNS

摘要

A dynamics of changes of length and diameter of different parts of common bile duct has been traced on 65 corpses of human fetuses and newborns by means of macro- and microscopic preparation and morphometry methods. It has been established that the growth of common bile duct has asynchronous character with alternation of the periods of acceleration (5-7 and 9-10 months) and delay (8 months) during the fetal period of human ontogenesis. The features of the growth of common bile duct are caused by different character of its parts formation. The original method of determining the evaluation criteria of development of common bile duct in fetuses and newborns is based on the obtained data and can be used for an early prenatal diagnosis of malformations and congenital diseases of extrahepatic bile ducts.
