Eevaluation of short-term efficacy of stent treatment on 48 patients with bengin tracheal stenosis

Abstract

Objective To evaluate the short-term efficacy of stent insertion through bronchoscopy for the treatment of bengin tracheal stenosis. Methods The data of 48 patients with benign tracheal stenosis were retrospectively analysed. The changes of tracheal diameter, forced expiratory volume in the first second, and dyspnea index were observed through bronchoscopy before and after stent insertion. Results Tracheal diameter increased from (5.15 ±1.96) mm to ( 10.60 ± 2.88) mm ( P ＜0. 01 ). Forcedexpiratory volume in the first second increased from (1.45±0.51) L to (2.46±0.48) L ( P ＜0.01).Dyspnea index decreased from 3.06±0.85 to 0.88±0.33 ( P＜0.01).Conclusions The short-term efficacy of stent insertion through bronchoscopy is clear for the treatment of bengin tracheal stenosis, but there may be some complications.
