[Mechanical sutures in digestive surgery. II. An experimental study of the cicatricial repair process]

The AA. intend to study the healing process of digestive sutures in dog that have been made with mechanical instruments that have metal agraphes. The used instruments are the American models of United Surgical Corporation in New York that have: --LDS pliers; --GIA pliers; --TA mod 90, 55, 30, pliers. They had made 15 operations of digestive surgery: gastric resections sec. Billroth II, anastomoses of ileum, colic anastomoses. In total they have made 45 sutures. After an established period the same animals were operated on again for controlling the results of made operations and the macro and microscopic evolution of sutures. The study of healing has shown a quick and exact repairing process for first intent, different from sutures that are made manually with threads that, notoriously, develop slowly for second intent.
