Some general principles of tissue crushing and regeneration during sutureless anastomosis of hollow organs of the alimentary tract.

: Tissues of the hollow organs of the gastrointestinal tract are crushed in order to create an anastomosis. The processes taking place in the tissues have been inadequately studied. A model of the tissue crushing process is suggested and the results of theory and experiments are compared. Dependence of the rejection time of the crushing influence on the crushing force was demonstrated experimentally. The relationship obtained can be explained on the grounds that migration of cell destruction products from the zone of crushing to the zones of healing stimulates adequate cellular immunologic processes. The views developed in this paper may prove useful for the elaboration of new surgical techniques.
