Emprego do compósito látex, poliamida e polilisina a 0,1% na correção cirúrgica de hérnias umbilicais recidivantes em bovinos leiteiros

Biologic and synthetic implants has been utilized frequently in experimental surgery with promising results. This work aims to value the utilization of the 0.1% polylisin and poliamide, latex membrane as graft in the recidivanting umbilical hernioplasty in cattle. Twelve crossbred, male, bovines (8-10 months) were used in the study. The herniopalstys were realized with the juxtaposition of the membrane over the hernial ring. Diary clinic valuations were performed through scores. Inflammatory process (0-3), wound dehiscence (0-2), abscess (0-1), fistula (0-1) and recidivation (0-1) were considered. Macroscopic evaluation of the implant local and samples collection to histopathological examination were realized in two animals on 15, two on 30 and two on 45 days post-surgery. Inflammatory process with score 1 was observed in all animals on 10 day. After biopsy, it was noted inflammatory process of score 3 in six bovines, wound dehiscence with score 1 in four animals and with score 2 in two bovines. Young conjunctive and muscular tissues were intensily associated, promoting stability and cicatricial repair. In the 15th day, angiogenesis were observed associated to the fibroblasts and infiltration of macrophages, lymphocytes and plasma cells. There was predominance of collagen in the periphery of the lesion. In the 30th day, it was noted conjunctive bunches, discrete angiogenesis and infiltration of macrophages. In the 40th day, it were observed similar microscopic characteristics to noted in 30th day. It was conclued that the 0.1% polylisin and poliamide, latex membrane is efficacious in the umbilical hernioplasty in cattle.
