Results of the application of apparatus AKA-2 for the formation of compressive anastomoses under complicated conditions are discussed. Among them are: acute and chronic ileus, peritonitis, diabetes mellitus etc. Common negative factors for all the patients were symptoms of secondary immune deficiency and specific endogenous intoxication resulting from chronic internal irradiation by radionuclides (consequences of the disaster in Chernobyl atomic power station in 1986). In 1987-1990 operations were performed on 84 patients. Compressive colonic anastomoses were made with apparatus AKA-2. All the patients lived in Kiev and neighbouring regions from 1986. From the patients operated upon 81% had colorectal cancer localized in left portions of the colon, 19% of the patients had inflammatory diseases of the colon. The application of compressive colonic anastomoses under the complicated conditions proved to be sufficiently reliable in the nearest and late terms of observations.
