Biomechanical and surgical aspects of child esophagus substitution with stomach, intestinum, and colon

Experimental research has been carried out on the biomechanical properties of the walls of esophagus, stomach, intestinum and colon at stretching, in the age range of a newly born up to 15 years. The authors have compared the resistance and the deformation properties of the hollow organs of children's digestive tract to clarify the biomechanical compatibility of various autotransplants for esophagus substitution in the case of various inborn and acquired pathologies. Essential disparities or mechanic parameters of esophagus, stomach, intestinum and colon walls have been observed, which from the biomechanical point of view suggest that the material of stomach, intestinum and colon is not suitable for the substitution of esophagus. Methods of alternative surgery have been studied, which reduce the permanent stretch of esophagus segments in the process of anastomoses laying, such allowing to avoid any esophagus transplantation. The biomechanical parameters of hollow organ wall of the digestive tract have been described more precisely, depending on the child age and the direction of the stretch.
