Abstract
The aim of this investigation was to investigate the strength and deformation properties of the human oesophagus wall in normal and pathological cases, in three anatomical parts of the organ, in persons ranging from the age of 19 to 89 years. The oesophagus wall displays anisotropy and non-uniformity of mechanical properties in longitudinal and circumferential directions. Higher resistance of the oesophageal wall occurs in the longitudinal direction. Longitudinally oriented collagenous fibres and their bundles determine the higher wall stiffness in this direction. Oesophagus stresses and strains are the greatest in the cervical part for all age groups. With age, the values of mechanical parameters of the oesophagus wall reduce, in particular beginning from 45 years, but the modulus of elasticity increases.
