RACIONAL: Na cirurgia geral, as correções das hérnias da parede abdominal ocupam lugar de destaque e, cada vez mais, as indicações e usos de telas têm aumentado devido aos melhores resultados. OBJETIVO: Comparar as correções de orifícios produzidos em parede abdominal com telas Parietex® e Surgisis® em contato direto com as vísceras abdominais. MÉTODO: Para os experimentos foram utilizadas 16 coelhas adultas jovens e produção de defeitos triangulares de 2 cm de base por 2,5 cm de altura, comprometendo os planos músculo-aponeurótico-peritoniais da parede abdominal, nos flancos, simétricos à linha média que foram corrigidos com telas retangulares de 3 cm de base por 3,5 cm de altura. No lado direito usou-se tela Parietex® (poliéster/colágeno-polietilenoglicol-glicerol) e no lado esquerdo tela Surgisis® (submucosa intestinal suína). Na avaliação utilizaram-se parâmetros clínico-cirúrgicos, histológicos e imunoistoquímicos. Oito coelhas foram submetidas a eutanásia em 30 dias e as 8 restantes, em 60. Comparou-se a eficiência das duas telas. RESULTADOS: As duas telas provocaram erosões de pele e não ocorreu nenhum caso de hérnia incisional. As aderências ocorreram em todas as telas no primeiro mês e em menor grau e intensidade, no segundo mês; a retração delas foi de 1/3 do tamanho original; a Parietex® provocou menor processo inflamatório; não houve diferença significante de deposição de entre as duas telas; a deposição do colágeno tipo III foi mais intensa no segundo mês em ambas; na remodelação do colágeno a produção da enzima MMP8 foi maior na tela Parietex® no primeiro mês e a enzima MMP13 aumentou no segundo mês em ambas as telas, porém com significância apenas na Parietex®. CONCLUSÃO: As duas telas foram eficientes na correção de hérnias incisionais e com resultados semelhantes, sendo que a Parietex® apresentou menor processo inflamatório, maior quantidade de metaloproteinases MMP8 e MMP13 em relação à Surgisis®.BACKGROUND: In general surgery, the repair of abdominal wall hernias has a prominent place, and the indications and uses of meshes have increased due to better results. AIM: To compare the repair of induced abdominal wall defects with Parietex® and Surgisis® meshes, in direct contact with abdominal viscera (intraperitoneal mesh). METHOD: For the experiments, were used 16 female young adult rabbits. Two full thickness triangular defects of 2 cm base by 2.5 cm high were created, lateral to the linea alba, one at each side. They were repaired with rectangular meshes of 3 cm base by 3.5 cm high, on the right side with Parietex® mesh (polyester/collagen-polyethylenglycol-glycerol), and on the left side with Surgisis® mesh (lyophilized porcine small bowel submucosa). The evaluation included clinical-surgical findings as well as histological and immunohistochemical parameters. Eight rabbits were subjected to euthanasia after 30 days, and the eight after 60 days. RESULTS: Both meshes induced skin erosions, despite the varying levels of mesh undermining evaluated, no incisional hernia occurred. There were peritoneal adhesions to the surface of both types of meshes after 30 days and in a lower extent and intensity after 60 days. Meshes' shrinking correspond to 1/3 of the original size and Parietex® caused less inflammatory process at the histologic evaluation. Deposition of collagen type I presented no significant difference between the meshes, but deposition of collagen type III was more intense after 60 days, in both groups. Regarding collagen's rearrangement, the production of MMP8 was higher on Parietex® after 30 days, and MMP13 enzyme was increased after 60 days, in both meshes (significant only for Parietex®). CONCLUSION: Both meshes were efficient in the correction of abdominal wall defects, and with similar results, but Parietex® presented less inflammatory process and greater amount of matrix-metalloproteinases MMP8 and MMP13 than Surgisis®.

Objective: To assess quality of life before and after thoracoscopic sympathectomy for treatment of primary hyperhidrosis.Methods: we conducted an observational, analytical, cross-sectional and quantitative study. We evaluated patients undergoing thoracoscopic sympathectomy for primary axillary hyperhidrosis, primary palmar hyperhidrosis, and axillary hyperhidrosis associated with palmar one. We applied a questionnaire on quality of life related to hyperhidrosis before and after the operation.Results: The questionnaire was administered to 51 patients with a mean age of 32.4 years, 45 women and six men. The average quality of life related to hyperhidrosis in a score of 0-100 before sympathectomy was 34.6 and after the operation it was 77.1. Compensatory hyperhidrosis occurred in 84.3% of patients.Conclusion: thoracoscopic sympathectomy improves the quality of life of patients with primary hyperhidrosis, with results supported over time. Compensatory hyperhidrosis occurred in most patients, but did not significantly influence the improved quality of life.
