Abstract: Objective To explore clinical value of the hypercator through flexible fiberoptic bronchoscope in management of the central tracheobronchial stenosis resulted by tumors. Methods Thirty-eight tumor (malignant and benign) cases with the central tracheobronchial stenosis were treated with the hypercator through flexible fiberoptic bronchoscope. Improvement of clinical features, atelectasis, airway diameters and pulmonary function were evaluated after treatment. ResultsThrough treatment, the clinical symptoms such as frequent expectoration, fever and dyspnea were released completely, and irritable cough (94.4%), hemoptysis (87.5%) were greatly improved. The recovery rate of atelectasis was 92%. The unobstructed,central airway was observed either malignant or benign tumors were 100% at the end of treatment, and still 94.7% 3 monthes later. There were significant differences in the dyspnea index and pulmonary function between before and after treatment(P<0.001). Seldom complications and low relapse rate were found in these patients. Conclusion The hypercator through flexible fiberoptic bronchoscope was a simple, effective and safe method to treat the central tracheobronchial stenosis induced by tumors, and widely utilized in our country.
