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

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

Desmoid tumor of the mediastinum

A desmoid tumor of the mediastinum was diagnosed and terated in a 35 year-old white male who presented with a right supraclavicular mass. He was treated with resection, which involved several vascular structures, requiring multiple vascular reconstructions followed by postoperative radiotherapy. The authors concluded that, when located in tha mediastinum, the invasive character of such tumors and its tendency to recur may pose a considerable surgical challenge, requiring careful preoperative planing and postoperative planning follow-up. The role of radiation therapy is limited to the control of local recurrences
