Summary
This pilot study tests whether adding a liquid nitrogen cryospray to standard treatments (balloon dilation or laser incision) can prevent benign airway stenosis from coming back within 6 months. About 12 adults with significant tracheal narrowing will receive the cryospray during a bronchoscopy. The main goal is to see if the airway stays more open on CT scans compared to personal best.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
liquid nitrogen cryospray (truFreeze device)
What this could lead to
If it works, this could point toward a better way to prevent airway narrowing from coming back after treatment, reducing the need for repeat procedures.
What could go wrong
This is a very early pilot study with only 12 people, so results may not apply broadly. The added cryospray could cause side effects like tissue damage or infection.
