Area of Science:

  • Pulmonology
  • Laser Surgery
  • Oncology

Background:

  • Tracheobronchial obstruction poses a significant risk of asphyxia.
  • Endoscopic resection is a critical intervention for managing airway compromise.
  • Neodymium-doped Yttrium Aluminum Garnet (Nd-YAG) laser technology offers precise therapeutic options.

Purpose of the Study:

  • To detail the application of Nd-YAG laser for endoscopic resection in airway obstruction.
  • To highlight the technical aspects and indications for laser use in bronchoscopy.
  • To evaluate the efficacy of advanced laser techniques and adjunct therapies.

Main Methods:

  • Rigid bronchoscopy under general anesthesia is mandatory for laser application.
  • A Nd-YAG laser (1.06 wavelength, max 100 watts) with 200-micron flexible fibers was employed.

  • Superpulsed laser emission mode was utilized for tissue evaporation, and cryotherapy was considered for bleeding control.

    • Main Results:

    • The Nd-YAG laser, particularly with flexible fibers, enables effective endobronchial applications.
    • Superpulsed mode facilitates tissue evaporation, minimizing carbonization and improving resection quality.
    • Adjunctive cryotherapy and endoprotheses can enhance the therapeutic effects of laser recanalization.

    Conclusions:

    • Nd-YAG laser endoscopic resection is a viable treatment for tracheobronchial obstruction.
    • Flexible fibers and superpulsed modes represent advancements in endobronchial laser therapy.
    • Combined with cryotherapy and endoprotheses, laser treatment offers comprehensive management for airway stenosis, especially in advanced carcinomas.
