Objective:
To describe in a retrospective study our experience in endoscopic management of tracheobronchial stenosis with 145 stents (11 different models).
Methods:
We analyzed the medical records of 103 patients (67 males and 36 females) who underwent the placement of prosthesis for any causes of tracheobronchial stenoses between 1990 and 2005.
Results:
A total of 145 prostheses were placed. Of these, 96.1% of the patients had a relief of dyspnea, and 73.8% had only one prosthesis. Stent removal and replacement were significantly linked with etiologies (more frequently in patients with an inflammatory component), but not with the type of stent.
Conclusion:
Endostenting is a safe and effective treatment for tracheobronchial stenoses. Removal and replacements were due to etiologies of the strictures, but not to the type of stent. Stenoses with an inflammatory component were prone to iterative stenting. Only benign diseases that are a contra-indication to open surgery should be treated by endoscopic stenting.
