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.
