[Application of endostents in tumor and scarry stenoses and main bronchi]

To evaluate advantages and shortcomings of Dumon's, T-shape and polyflex endotracheal stents in patients with tumor and scarry stenoses of the trachea and main bronchi, we analysed the results of stenting trachea and main bronchi in 180 patients for 11 years (1992-2002). We observed the highest rate of granulations and dislocations for polyflex stents in the lowest adhesion of the sputum to their walls. Long-term results of stenting in scarry tracheostenosis demonstrate a moderate efficacy of T-stents and low efficacy of Dumon's stents. Our final conclusion is that a key method of treatment of tracheal scarry stenoses is a circulatory resection of the stenosed zone. Tracheal stenting remains important in urgent necessity of the treatment of decompensated stenoses, in preparation for radical operation and in contraindications to the latter.
