Laser in bronchology: methods of application.

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.
