“…Bellon et al 10 , studying lightweight partially absorbable material, concluded that it may offer advantages over underweight non-absorbable meshes material, since less foreign body remains in the patient, enabling improvement in the abdominal wall. The animals were kept under constant light and temperature conditions in standard cages, being fed with commercial diet and free access to water.…”

PURPOSE:To evaluate the healing process of a defect in the ventral abdominal wall of rats, comparing the polypropylene and polypropylene/poliglecaprone meshes on the 30 th and 60 th postoperative day. METHODS: Thirty two Wistar rats were submitted to a ventral abdominal wall defect, with integrity of the parietal peritoneum. In the repair, were used polypropylene (group A) and polypropylene/poliglecaprone (group B) meshes. The groups were subdivided into four subgroups of eight animals euthanized on the 30 th (A30 and B30) and 60 th postoperative day (A60 and B60). Fragments of the abdominal wall of the animals were submitted to macroscopic, tensiometric and histological evaluations. RESULTS:The tensiometry on subgroup A30 showed a mean average break point of 0.78 MPa and in A60, 0.66 Mpa. In subgroup B30 it was 0.84 MPa and in B60, 1.27 Mpa. The score of the inflammatory process showed subacute phase on A30 and B30 sub-groups and chronic inflammatory process in subgroups A30 and 60B. CONCLUSIONS: The tensile strength was higher on the wall repaired by polypropylene/poliglecaprone mesh in the 60 th post-operative day. Histology showed higher concentration of fibrosis on the surface of the polypropylene mesh with a tendency to encapsulation. In polypropylene/poliglecaprone subgroups the histology showed higher concentration of fibrosis on the surface of mesh filaments. Key words: Surgical Mesh. Hernia, Abdominal. Polypropylenes. Rats. RESUMO OBJETIVO: Avaliar a cicatrização de um defeito, na parede abdominal ventral de ratos, comparando-se as telas de polipropileno e polipropileno/poliglecaprone no 30º e 60º dia do pós-operatório. MÉTODOS: Trinta e dois ratos Wistar foram submetidos à produção de defeito na parede abdominal ventral, com integridade do peritônio parietal. Na correção foram utilizadas as telas de polipropileno (grupo A) e polipropileno/poliglecaprone (grupo B). Houve subdivisão em quatro subgrupos (A30, A60, B30 e B60) de oito animais que foram submetidos à eutanásia no 30º e 60º dia do pós-operatório. Fragmentos da parede abdominal foram submetidos à análise macroscópica, tensiométrica e histológica. RESULTADOS: A tensiometria no subgrupo A30 mostrou tensão média de ruptura de 0,78 Mpa e no subgrupo A60 de 0,66 MPa. No subgrupo B30 foi de 0,84 MPa e no B60 de 1,27 MPa. O escore do processo inflamatório mostrou fase subaguda nos subgrupos A30 e B30 e processo inflamatório crônico no subgrupo A60 e B60. CONCLUSÕES: A resistência à tensão foi maior na parede reparada pela tela de polipropileno/poliglecaprone no 60° dia pós-operatório. Na análise histológica houve maior concentração da fibrose na superfície da tela de polipropileno com tendência ao encapsulamento. Nos subgrupos polipropileno/poliglecaprone a análise histológica mostrou maior fibrose entre os filamentos da tela. Descritores: Telas Cirúrgicas. Hérnia Abdominal. Polipropilenos.

“…When inserted intraperitoneally, in general a mesh induces a foreign body reaction and the Experimental studies with surgical meshes for evaluation of biocompatibility and adhesion formation use animal models, such as rabbits [23][24][25] , sheep 26 , pigs 15 , and, especially, rats 11,27 . The variables analyzed include incidence, extent, quality and, in some studies, resistance to rupture and tenacity.…”

Objective: to compare intraperitoneal adhesion formation in rats when using polypropylene and polypropylene with poliglecaprone meshes. Methods: we used twenty male, Wistar rats, divided in two groups. In group 1, the rats received the polypropylene mesh on their right side and the polypropylene with poliglecaprone mesh on their left side. In group 2 the position of the meshes was inverted. After 30 days, we analyzed the presence or not of adhesion formation, including only those over the meshes. The findings undergone an analysis through the Mann-Whitney test, at a level of significance of p≤0.05. Results: all meshes presented adhesions. We verified that, for the polypropylene meshes, the percentage of their surface covered by adhesions varied from 10.5 to 100%, with an average of 34.07±24.21%, while for the polypropylene with poliglecaprone mesh, the percentage covered by adhesions varied between 8.5% and 100%, with an average of 44.7±32.85% (p=0.12). Conclusion: both meshes lead to adhesion formation, none being superior to the other.
