RESUMO

In this study was evaluate, macroscopically and microscopically, the healing process of intestinal anastomoses in dogs using polyglecaprone 25, polyglactin 910 and cotton sutures. Twenty mongrel dogs, weighting from 9 to 16 Kg were submitted, under general inhalatory anesthesia, to three small intestine anastomoses. The animals were divided into four groups, in accordance with the postoperative observation periods as follows: group I, three days; group II, seven days; group III, fourteen days; group IV, twenty one days. Extramucous technique was used, with those threads, in all four groups. After the observation period the animals were euthanized and samples from the operative site were collected for macroscopic and microscopic evaluations. Macroscopically, all three threads showed good behavior with good coaptation of the edges; however, there occurred a moderate level of adherence between loops of intestine and omentum, from day 3 to day 21, of postoperative period. Microscopically, there was exsudative inflammation, with neutrophils and fibrin, discrete to moderate until day 14. Granulomatous inflammation was also notice accompanied by macrophages, multinucleated giant cells and epithelioid cells, more evident on day 14 in the cotton group. Granulation tissue (fibroblasts) and collagen fibers were also observed, in a moderate pattern, for all three suture materials, from day 7. All three suture threads used in this research showed similar behavior and thus they can be indicated for anastomoses of the small intestine in dogs
