Reacción tisular a materiales de sutura no absorbibles en piel de equinos Tissue reaction to nonabsorbable suture materials in horse skin

SUMMARY The degree of tissue reaction of 4 nonabsorbable suture materials (linen, nylon, polymerized caprolactum and polypropylene)implanted into health skin of 8 horses was clinically and histologically evaluated. Cutaneous oedema and absence or presence of theexudation were clinically evaluated 5 and 10 days following suture material implantation. Biopsies were taken to histologicallyevaluate tissue reaction at 10 days. The results obtained showed that linen caused more oedema by the 5 th day, whereas the nylon andcaprolactum had less oedema on the 10 th day. With respect to the presence or absence of exudation, nylon was the only materialwhich did not show exudation by the 5 th day in any of the 8 samples, but on the 10 th day, neither the nylon, caprolactum or polypropyleneshowed exudation, except one horse that showed exudation for all suture materials. The histological evaluation showed that nylonand caprolactum caused less tissue reaction. In conclusion, linen was found to have a higher degree of tissue reaction in the presentstudy, and nylon although similar to caprolactum and polypropylene in terms of tissue reaction, caused less cases of exudate th an theother suture materials used.
