RESUMO

The purpose of this work was to compare the tensile resistance and the evolution of the tissue reaction of the rats abdominal wall, submitted to the mediana incision and abdominal wound closing by three different techniques: closing by plans, closing by plans completed with subtotal points and closing by plans completed with a Poliglactina 910 screen, studied in the first, the seventh and fourteenth post-operative days. 90 Wystar rats were studied, divided into three groups of 30 in each one in which the techniques described were conducted and afterwards subdivided into nine subgroups of 10 rats each, in which the test of tensile resistance was realized. The study was made in the vivarium in the Faculdade de Ciências Médicas da Universidade São Francisco. The resistance test used for checking the resistance, the rupture was described by Udupa in 1969. After the realization of the test a resection was made in a part of the surgical wound and forwarged for a microscopical study: this study was made at the Departamento de Patologia da Universidade São Francisco. The results obtained in the tensile resistance test showed that the techniques of the abdominal wound closing, complemented witn reinforcement give greater resistance to the traction of the abdominal wall in the first post-operative days. The comparison of the tissue reaction observed in this work showed an increase of the reaction in the subgroups of rats in which the techniques of reinforcement were used, being more intense when using the Poliglactina 910 screen. It was concluded therefore, that the methods of closing the abdominal wound wall in rats, when using the reinforcement, gave a greater resistance to the traction in the abdominal wall in the first post-operative days. In relation to the tissue reaction, this is greater when using the reinforcement techniques
