Bronchoscopic interventions for severe emphysema: Where are we now?

Area of Science:

• Pulmonology
• Interventional Pulmonology
• Respiratory Medicine

Background:

• Severe emphysema presents limited therapeutic avenues, with optimal medical treatment offering minimal patient benefit.
• Surgical lung volume reduction (LVRS) is effective but perceived as high-risk and invasive, driving interest in less invasive alternatives.

Purpose of the Study:

• To review the current landscape of bronchoscopic lung volume reduction techniques for severe emphysema.
• To highlight the progression of these techniques from clinical trials to practical application.

Main Methods:

• Discussion of various bronchoscopic methods including endobronchial valves (EBV), airway bypass, endobronchial coils, and thermal or chemical sclerosis.
• Emphasis on the critical role of patient selection for successful outcomes.

Main Results:

• Bronchoscopic approaches have emerged as viable alternatives to surgical LVRS.
• Multiple techniques are available, each with specific mechanisms for lung volume reduction.

Conclusions:

• Bronchoscopic lung volume reduction represents a significant advancement in managing severe emphysema.
• Careful patient selection is paramount for optimizing the efficacy of these minimally invasive procedures.
