METHODS FOR EXPERIMENTAL ANASTOMOSES PROTECTION ON THE COLUMN

The paper presents the results of an experimental research on small animals (rats) whose purpose is to check upon efficiency of the protection methods for suppressing dehiscence of the column anastomoses.The research is carried out on 90 experimental animals divided into three groups of 30. In the control group (group K) the segment resection of the left side of the column is done with termino-terminal anastomosis by a one-layer extension suture. In the II animal group the anastomosis protection is done by intraluminal application of latex prosthesis (group L) and in the III group the fibrin adhesive or bio adhesive application is done (group F). The complete dehiscence of anastomosis as the cause of mortality in the group K is registered in 3 (10%) cases while in the group L in 2 (6,6%) animals. In the group F there is no dehiscence with the energence of diffuse peritonitis. By applying the protection methods in performing on the column better results are achieved and they are manifested in a smaller number of dehiscences. The local application of the fibrin adhesive provides for the best results since the good mechanical protection is achieved while at the same time the healing time of the column anastomoses is shortened.
