Resumo
Em eqüinos, as enterotomias no cólon descendente são necessárias para remover enterólitos, corpos estranhos e material alimentar compactado que não podem ser removidos por técnicas conservativas. Este segmento intestinal possui um suprimento sangüíneo pobre, além de predisposição a complicações pós-operatórias relacionadas à contaminação bacteriana. Assim, este estudo foi conduzido com o objetivo de efetuar avaliações clínicas e anatomopatológicas do emprego de adesivo tecidual à base de cianoacrilato no cólon descendente de eqüinos, comparando-o a uma técnica de sutura aposicional convencional. A intervenção cirúrgica foi realizada em 15 animais posicionados em decúbito lateral direito, através de laparotomia pelo flanco esquerdo, sob anestesia geral inalatória. Após a exteriorização do cólon descendente, foram realizadas duas enterotomias de cinco centímetros de extensão cada, distanciadas 20cm uma da outra. Os animais foram aleatoriamente distribuídos em cinco tempos de observação de três animais cada e sacrificados aos três, sete, 14, 35 e 70 dias de pós-operatório. O adesivo butil-2-cianoacrilato e o fio de poliglactina 910 mostraram-se igualmente apropriados para uso em enterorrafias desse órgão, sendo que o fio de poliglactina 910 provocou inflamação inicial mais intensa que o cianoacrilato e, mais tardiamente, ambos causaram inflamação granulomatosa do tipo corpo estranho observada, primeiramente, junto ao fio de poliglactina 910 (7º dia) e, a partir do 35º dia, ao redor do cianoacrilato.
The descending colon enterotomies in horses are necessary to remove enteroliths, foreign body and impacted material that can not be removed with conservative technique. This intestinal segment has a poor blood supply and the predisposition to post operation complications related to bacterium contamination. This trial was conducted in order to evaluate, clinically and anatomopathologically, the use of tissue adhesive of cyanoacrilate in the equine descending colon and to compare with an apposition pattern. Fifteen horses were used. Surgical intervention was done using laparotomy by the left flank, with the animals in right lateral recumbent position, under inhaler anesthesia. After exteriorization of the descending colon, two five-centimeter-long enterotomies were done, 20cm apart one from the other. The horses were randomly distributed in five groups of three animals each. After human methods of euthanasia, necropsy was done with complete examination and documentation of sutured areas of the descending colon on post operation (days 3,7,14,35 and 70), one group at each time. The butyl-2-cyanoacrilate and the suture thread poliglactin 910 both showed that they are appropriate to be used in enterorrhaphies of this organ. The suture thread poliglactin 910 caused more intense initial inflamation compared to the cyanoacrilate, and later, both caused granulomatous inflammatory of the sort of foreign body. This was observed, firstly, in the suture thread poliglactin 910 (on day seven) and starting from the day 35 around cyanoacrilate.
