Abstract
Upper tracheal stenosis is considered as a potentially life-threatening condition. Silicone stenting is an attractive treatment option for patients with upper tracheal stenosis. However, its use has been compromised by a major complication, stent migration. In the report, we introduced a novel external fixation of silicone stent which only needed one puncture site and involved a silicon chip as an anchoring device. All equipment and materials including the silicon chip were available in routine bronchoscopy suite. The method had been successfully performed in three patients with upper tracheal stenosis at our institution. And the patients were monitored for over 20 months after the intervention, and no spontaneous stent migration occurred. Therefore, we believe this is a simple and reliable approach for improving the outcome of silicone stenting in patients with upper tracheal stenosis and should be introduced in clinical practice.
