Effects of polypropylene prosthesis placed by inguinotomy in the preperitonial space, in dogs: evaluation laparoscopic and microscopic

摘要

PURPOSE: Observing the effects produced by the prosthesis of polypropylene in the pré-peritoneal space in dogs METHODS: 10 adult cross-bread dogs (n=10) have been put trough bilateral inguinotomy where prosthesis was put on one of its sides. In the contra-lateral region, the procedure was the same, but without the use of prosthesis, serving as a control. After 30 days the animals had been submitted to a laparoscopic technique and a macroscopic evaluation was made via intraperitoneal besides being through a biopsy of fragments of the peritoneum to record histological alterations of the two inguinal regions. RESULTS: Three of the animals presented adhesions in the local of the polypropylene prosthesis was placed. No animal presented adhesion in the local without prosthesis. The microscopically alterations in side A (with prosthesis) were characterized by the proliferation of dense fibrous conjunctive tissue, besides the lack of presence of giant multinuclear showing a light inflammatory reaction. CONCLUSION: The prosthesis of polypropylene induce the formation of adhesions, when placed in the pre-peritoneal space of dogs
