Bronchoscopic device intervention in chronic obstructive pulmonary disease.

Area of Science:

• Pulmonary Medicine
• Interventional Pulmonology
• Respiratory Disease Research

Background:

• Chronic obstructive pulmonary disease (COPD) is a complex respiratory condition characterized by emphysema and airway inflammation, leading to reduced lung function, exercise tolerance, and quality of life.
• Standard medical therapies often fail to fully restore lung function or improve quality of life in COPD patients.
• Surgical and minimally invasive bronchoscopic lung volume reduction techniques have emerged to address these persistent impairments.

Purpose of the Study:

• To provide a narrative review of current and emerging minimally invasive bronchoscopic technologies for lung volume reduction in COPD.
• To discuss the selection criteria and personalized approach required for different bronchoscopic interventions.

Main Methods:

• Review of available literature on bronchoscopic lung volume reduction techniques for COPD.
• Analysis of Food and Drug Administration (FDA)-approved devices and ongoing investigations.
• Examination of patient selection criteria, including physiologic, radiographic, and comorbidity factors.

Main Results:

• Lung volume reduction surgery, while effective for survival in select patients, is underutilized.
• Less invasive bronchoscopic procedures, such as endobronchial valves, coils, lung sealant, and thermal vapor, are being explored as alternatives.
• Two endobronchial valve systems are FDA-approved, with ongoing research into other bronchoscopic therapies for emphysema and chronic bronchitis.

Conclusions:

• Minimally invasive bronchoscopic lung volume reduction offers promising alternatives to traditional surgery for COPD.
• Each bronchoscopic treatment modality has specific patient selection criteria, necessitating a personalized treatment strategy.
• Continued research and development in bronchoscopic therapies are crucial for advancing COPD management.
