[Small and large intestine devascularization (devitalization) and potentials in the therapeutic use of this operative method].

The experimental findings with devitalization of various intestinal segments by means of devascularization showed that the isolated segments left in peritoneal cavity (together with their contents) were gradually destroyed and changed into a slight fibrous residue. The retaining of the up to 180 cm long segment did not endanger the life of experimental animals. This experience was used in the surgical treatment of inoperable tumours in left half of large intestine and in rectosigmoideum. The case report of four successful operations is given together with two cases of invagination of the devitalized part into intestinal lumen.
