Experimental devascularization (devitalization) of the rectum and sigmoideum.
In 6 laboratory pigs, devascularization (devitalization) of the rectum and the adjacent part of the sigmoideum was carried out by the vasa rectalia cranialia et media ligatures with simultaneous aboral closure of the rectum at the base of the lesser pelvis and oral closure at the borderline between the rectum and the sigmoideum. The devascularized rectum was not removed but left in situ. Terminal colostomy was established. Laparotomic revision was carried out after 12 weeks, colostomy was removed and continuity of the intestine was reestablished by insertion anastomosis, by suture of the end of the colon to the anal mucosa and skin. In further two pigs, devascularization of the rectosigmoideum was carried out with colostomy and reconstruction was carried out after 12 weeks by procto-sigmoideo-anastomosis. In another 2 animals, devascularization was carried out on the lower part of the sigmoideum and continuity was immediately renewed by end-to-side sigmoideo-sigmo-ideoanastomosis. All revisions indicated that the devascularized necrotic segment shrank to form a minute fibrous tissue residue, anastomosis was patent and continence was retained for colo-proctoanastomosis. The described techniques are technically simple and could be employed as palliative surgical methods for inoperable tumours in the region of the rectum and lower part of the sigmoideum.
