title: [The cause and efficacy of benign tracheal stenosis].
abstract: OBJECTIVE
  To analysis the causes of benign tracheal stenosis and evaluate the curative effect of intraluminal bronchoscopic treatment.
  
  
  METHODS
  158 patients with benign tracheal stenosis in our hospital from September 2005 to September 2012 were collected to retrospectively analysis the causes and clinic features of tracheal stenosis. Interventional treatments through bronchoscopy were used to treat the benign tracheal stenosis and the curative effects were evaluated.
  
  
  RESULTS
  158 cases of benign tracheal stenosis were recruited to our study, 69.6% of them were young and middle-aged. The main causes of benign tracheal stenosis were as follows: secondary to postintubation or tracheotomy in 61.4% (97/158), tuberculosis in 16% (26/158), benign tumor in 5.1% (8/158) and other 27 cases. 94.3% patients improved in symptoms with alleviation immediately after bronchoscopic treatment, the average tracheal diameter increased form (4.22 ± 2.06) mm to (10.16 ± 2.99) mm (t = 21.48, P < 0.01), dyspnea index decreased from 2.29 ± 0.75 to 0.63 ± 0.67 (t = 19.85, P < 0.01). The recurrence rate in 1 and 3 month after interventional treatment were 38.3% and 26.8%, respectively.
  
  
  CONCLUSIONS
  The cases of benign tracheal stenosis were increasing year by year. The most common cause of benign tracheal stenosis was postintubation and tracheotomy. Interventional treatments through bronchoscopy is effective in treating benign tracheal stenosis, but repeated interventional procedures may be required to maintain the favorable long-term effects.
