Comparative study of different forms of protection in a rat model of bronchial fistula

ABSTRACT

The authors present the results obtained with the development of an experimental model of bronchial fistula and compared different forms of post-pneumonectomy bronchial fistula protection. Forty rats were submitted to left pneumonectomy and bronchial stumps were protected with either pedicled muscle ( N=20 ) or pedicled fat ( N=20 ). The results showed that it was possible to develop a fistula model in 65 por cento of animals and that there was no statistical difference ( p>0.05 ) between the tissues used for bronchial protection
