Study Arms:
- Mitomycin-C (Type: EXPERIMENTAL): Patients will undergo standard endoscopic surgical treatment for LTS involving CO2 laser radial incisions and balloon dilation, as well as topical application of MMC in the radial incisions.
- Saline (Type: PLACEBO_COMPARATOR): Patients will undergo standard endoscopic surgical treatment for LTS involving CO2 laser radial incisions and balloon dilation, as well as topical application of isotonic saline in the radial incisions.

Based on this trial design, predict the completion outcome and termination type (if applicable).
