摘要

Trinta ratos, linhagem Wistar, fêmeas, com peso inicial médio de 150 gramas, foram divididos em seis grupos de cinco animais, sendo o grupo I - dieta controle (ra??o comercial), grupo II - dieta controle + colotomia e síntese com sutura contínua simples; grupo III - dieta controle + colotomia e síntese com sutura tipo Cushing, grupo IV - dieta n?o balanceada, grupo V - dieta n?o balanceada + colotomia e síntese com sutura contínua simples, grupo VI - dieta n?o balanceada + colotomia e síntese com sutura tipo Cushing. A colotomia foi executada no cólon descendente e no quinto dia do pós-operatório os animais foram sacrificados para estudo da tens?o de ruptura, pelo método de explos?o, nos cólons transverso e descendente. A média do ganho de peso com a dieta n?o balanceada foi aproximadamente a metade da controle. N?o houve diferen?a estatística entre os tipos de sutura, nem entre o estado nutricional e técnicas de sutura. Em geral, os valores da tens?o de ruptura no cólon transverso intacto e no cólon descendente dos animais operados (dieta controle e n?o balanceada), foram inferiores ao dos n?o operados com dieta controle. O epíplon dos ratos dos grupos V e VI apresentou-se menos volumoso e adelga?ado, o que promoveu aderências graves de outros órg?os sobre a regi?o da colotomia. Essas ades?es podem ter interferido na avalia??o da tens?o de ruptura do cólon descendente. Foi possível concluir que o método de for?a de explos?o n?o permitiu estabelecer diferen?as entre os padr?es de sutura utilizados e o grau de nutri??o. Nutrition interference on mechanic resistance of colon and comparison of two suture techniques for colotomy closure in rats Abstract Thirty female Wistar rats with initial average weight of 150 g, were divided in six experimental groups as follows: group 1 - control diet (commercial rat food); group II - control diet and colostomy with simple continuous suture; group III - control diet and colostomy with Cushing?s pattern suture; group IV - unbalanced diet; group V - unbalanced diet and colostomy with simple continuous suture; group VI - unbalanced diet and colostomy with Cushing?s pattern suture. Colostomy was carried out in descending colon. At the fifth day after surgery, the animals underwent euthanasia in order to measure the bursting strength of the transverse and descending colon. The gain of weight in the unbalanced diet was almost half of the control diet. here were no statistic differences between the sutures patterns, neither in regard to the nutritional conditions and suture techniques. Generally, the bursting strength values measured in both colons of the animals under either control and unbalanced diets, that underwent surgery, were lower than the ones found for rats under control diet that did not underwent surgery. The omentum of the rats from groups V and VI was less voluminous and thin causing serious adhesions to other organs at the colostomy area. These adherences might have interfered in the evaluation of the bursting strength in the descending colon. According to the results found, it was possible to conclude that evaluation of the bursting strength did not allow to establish differences between the suture patterns and the nutritional conditions of the experimental animals.
