Objective:To assess the efficacy and safety of balloon dilatation using a fiberoptic bronchoscope in the man-agement of benign tracheobronchial stenosis.Methods:One hundred and fourteen patients with proximal benign tracheo-bronchial stenosis were managed by balloon using the flexible fiberoptic bronchoscope.Each patient underwent fiberoptic bronchoscopy,in which a balloon catheter was sent to stenosis segment from the working channel and positioned across the stenosis.Under direct visualization,the balloon was inflated for1to3min.Repeated inflation-deflation cycles were done if airway narrowing remained after the initial attempt.Airway diameters,dyspnea index and complications were evaluated in all patients and FEV 1 was tested in58cases before and after management.Results:Patients required a1-8sessions balloon man-agement with a mean of(3.22±1.24)sessions.After high pressure balloon dilatations,airway average diameter increased from(2.74±1.32)mm to(6.87±1.76)mm,P0.01.Dyspnea index decreased from(2.13±0.81)to(0.71±0.56),P0.01.FEV 1 increased from(1.32±0.62)L to(1.81±1.22)L,P0.01.No severe complication was found in all patients. Conclusion:Airwayplasty with high pressure balloon dilatation using flexible fiberoptic bronchoscope is an efficient,safe,sim-ple and rapid method for treatment of proximal benign tracheobronchial stenosis.
