[Nonspecific granulomatous inflammation in Crohn's disease].

A comparative morphological study of intestinal wall tissues in such chronic colonic diseases, such as Crohn's disease, ulcerative colitis, and catarrhal rectal fistulas, allows the formation of giant cells of foreign bodies and their granulomas and sarcoid-type ones to be nonspecific. Their spread through and outside the colon is due to the migration of foreign bodies along the lymphatic vessels. Foreign inclusions of different shapes and structures in the cytoplasm of giant cells suggest that the colon contains the multiple particles of varying antigenic nature, which induce a unified morphological response medicated by innate and adaptive immunity cells.

[The comparative analysis of the surgical treatment of the familial adenomatosis of the colon with the use of cell transplantation].

Authors represent the surgical technique of colectomy with preserving the natural intestinal passage in the treatment of the familial colic adenomatosis. The technique is based on the preserving the distal part of the rectum with its demucosation and connecting with the ileal conduit. The rectal mucosa reconstruction is performed with the use of allogenic transplantation of fetal intestinal cells.

Cell transplantation in surgical treatment of familial adenomatous polyposis coli.

We developed a method of surgical treatment of familial adenomatous polyposis coli giving an opportunity to prevent the growth of new polyps in the preserved part of the rectum and consisting in transplantation of fetal cells of the epithelial origin into the rectum wall after mucosectomy. Since the rectum is partially preserved, ileorectal anastomosis can be formed after colectomy, which preserves natural bowel passage. Complex examination 4 weeks after surgery revealed the formation of normal rectal mucosa.

[Role of vascular disorders in the pathogenesis of ulcerative colitis and its complications].

Mucous membrane circulatory disorders in ulcerative colitis (UC) are accompanied by significant capillary plethora with endothelial nuclear swelling in the capillaries and minor veins. Some cases show the development of secondary endophlebitis with thrombi occurring in individual veins. Occasionally, there is deep vein thrombosis in the leg with pulmonary embolism.

[The extension of a physiologic hypoganglionic area in adults and its significance in the diagnosis of Hirschprung's disease].

The purpose of the investigation was to study the extension of a physiologic hypoganglionic area in the distal rectum in adults and to define its implication in diagnosing Hirschprung's disease. Thirty-five cadaver distal rectal portions were examined. The extension of a physiologic hypoganglionic area in adults ranged from 7.
