Resumo
O objetivo deste experimento foi comparar a sutura contínua e a sutura com pontos separados no fechamento da parede abdominal. Foram utilizados 48 ratos machos Wistar, submetidos a laparotomia com técnica de diérese padronizada, 24 submetidos a sutura da parede abdominal por técnica contínua e 24 com pontos separados, com fio polidioxanona. No 7º e 14º dia de pós-operatório foram submetidos a eutanásia 12 animais de cada grupo e deles retirados a camada músculo-fascial abdominal envolvendo a cicatriz operatória e dividida aleatoriamente em dois segmentos (cranial e caudal), um para ser submetido a avaliação da força de rotura mediante o uso de tensiômetro e outro para exame histológico, onde foi realizada a avaliação quantitativa de colágeno na linha de sutura. Os resultados encontrados foram analisados estatisticamente. Concluiu-se que no 7º dia de pós-operatório a parede abdominal suturada com pontos separados é mais resistente, porém sem diferenças significantes na quantidade de colágeno, do que a suturada por técnica contínua, e no 14º dia, ambas se equivalem nos dois parâmetros estudados, em ratos.
The purpose of the experiment was to compare the continuous and interrupted techniques of abdominal clousure. It was used 48 male rats Wistar to realize longudinal laparotomies with a standardized technique. In 24 of them, the abdominal wall was closed by continuous suture and in 24 of them closed by interrupted suture. All of them using polidioxanone. In the 7th and 14th postoperative day, 12 animals of each group were submitted to euthanasia and the front abdominal wall was removed (without skin) and divided in two segmentes (cranial and caudal), one for hystological analysis with an objective measurament og collagenous and another to the test of tensile strength by tensiometer. The resultant data were submitted to statistical analysis. It was conclued that in the 7th day , the abdominal wall closed by interrupted technique is more resistant without significant diferences on collagenous density than the other closed by interrupted, and at the 14th day the results are similar, in rats.
