NCT ID NCT04719845
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study compared two procedures—laser resection and dilatation—for treating benign (non-cancerous) narrowing of the windpipe. The goal was to see which one better prevents the narrowing from coming back within two years. The trial was terminated early, so the results are limited.

What this could lead to
If successful, this could show which procedure is better at preventing the airway from narrowing again after treatment.
