Zubko L. Gender and age peculiarities of the structure and topography of the gallbladder and extrahepatic bile ducts in individuals of mature age

In the dissertation work the theoretical generalizations are carried out and the actual scientific problem on clarification of features and variants of a structure of a gall bladder and extrahepatic bile ducts at persons of mature age of different sex and research of laws of their morphological changes in age that allows to expand idea of reorganization of investigated structures during different periods of adulthood. According to the results of ultrasonographic examination of persons of different ages of adult age of males and females, the author for the first time analyzed the frequency of occurrence of different variants of gallbladder inflection, the frequency of asymptomatic bile stasis in persons of different sexes, clarified morphometric parameters (longitudinal and transverse gallbladder walls, width of the common bile duct) and their dynamics with age in persons of different sexes without pathology of the hepatoduodenal area. Based on the data of the analysis of a series of three-dimensional tomographic studies, the author for the first time analyzed and identified the frequency of gallbladder shape variants in adults of different sexes according to in vivo examination. For the first time the frequency and analysis of variants of topography of extrahepatic bile ducts in adults were established; the magnitude of the angle of confluence of the gallbladder into the common bile duct, the angle of ascent of the right and left hepatic ducts, specified linear dimensions of the gallbladder and extrahepatic bile ducts and their features in adults of different sexes, which creates the preconditions for the development of schemes for prevention, early diagnosis and treatment of pathological changes in the structures of the hepatobiliary system. The data on the above-mentioned studied objects have been clarified and supplemented during their lifetime, without violating the integrity of the organism.
