Abstract

Objectives: Endoscopic airway dilatation and stenting has been developed to treat the airway stenosis without potential morbidities of open surgery. We report the clinical results of endoscopic airway dilatation with silicone stenting in patients with posttuberculous bronchial stenosis(PTBS) and with severe main tracheal stenosis who have poor general conditions
Methods: A prospective observation study of five patients, who have undergone endoscopic airway dilatation and silicone stenting between Feb 2007 and Feb 2009. A total of twelve patients were treated with endoscopic airway dilatation, among them 5 patients were included in this study. three patients were treated with newly designed silicone stent (Natural stent: TNO Co., Seoul, South Korea) because of poor surgical conditions and longer stenotic segment
Results: 3 patients were grade III PTBS, and the other 2 patients were grade IV post tracheotomy main tracheal stenosis. One patient of PTBS were treated with silicone stent following endoscopic dilatation because of longer stenotic segment. Two patients of main tracheal stenosis patients were treated with silicone stent because of tracheal lumen collapse. There was no severe postoperative complications except mild granulation tissue formations
Conclusions: Endoscopic dilatation including silicone stenting could be a useful method for treating patients with PTBS, and for main tracheal stenosis patients with poor general surgical conditions
