[Experimental evaluation of a double-layer anastomosis of the large bowel in the dog following irradiation].

In our experiments on dogs we study the influence of irradiation on large bowel surgery. 24 dogs were divided in two groups: the control and the irradiated group. The dogs were irradiated and after 4 months the resections of 5 cm of the irradiated large intestine was performed. We used single and double layer anastomosis. Two weeks after the operation the dogs were sacrified and morphological, tensiometric and histological studies were applied to the operated and irradiated large intestine. Conclusion of our experiments is the statement, that the single layer intestinal suture satisfies in a greater degree the requirements of an ideal suture in the irradiated bowel than the double layer intestinal suture.
