Abstract
In the work, stress-strain curves in the longitudinal and annular directions were experimentally obtained and the differential elastic modules of the wall of the segment of the human common bile duct on cadaver material were determined. Knowledge of the physico-mechanical properties of the bile ducts can be used to understand the functioning of the entire human biliary system, to clarify aspects of its aging due to qualitative structural and functional changes in tissues, to diagnose diseases and for therapeutic purposes. One of the early manifestations of changes in the properties of the ductal wall caused by the development of a pathological process in it is a violation of its elasticity, which is reflected in an increase in stiffness indicators. It is established in the longitudinal direction of choledochus: kPa and kPa (regression confidence coefficient 0.99), in the annular direction – kPa and kPa (regression confidence coefficient 0.98), respectively.
