[High-frequency thermocoagulation. Use in bronchial endoscopy]

Area of Science:

• Pulmonology
• Oncology
• Medical Technology

Background:

• Tracheobronchial tumors present challenges for treatment.
• Existing methods may have limitations in efficacy or side effect profiles.

Purpose of the Study:

• To describe high frequency thermocoagulation (HF-TC) as a method for tracheobronchial tumor mass destruction.
• To highlight the advantages of HF-TC over other techniques.

Main Methods:

• Utilizes the thermal effect of electrical current (HF current) for tissue destruction.
• Employs unipolar electrodes (rigid or flexible) to deliver controlled heat (70-100°C).
• Newer generators with microprocessor control and fiberoptic bronchoscopes enhance safety and precision.

Main Results:

• Achieves immediate tissue destruction through heating and water vapor formation.
• Avoids electrolytic and faradic effects, minimizing nerve and muscle stimulation.
• Immediate effects are comparable to laser treatment.

Conclusions:

• HF-TC is a simple, fast, and minimally morbid technique for tracheobronchial tumor ablation.
• Its relatively low cost makes it an attractive option, even in resource-limited settings.
• Technological advancements are further optimizing the safety and efficacy of HF-TC.
