Introduction

This study evaluates the diagnostic effectiveness of navigational bronchoscopy, including electromagnetic navigation and ultrathin bronchoscopy, for peripheral lung lesions. It highlights the improved diagnostic yield with advanced techniques, particularly when combined with rapid on-site cytologic evaluation (ROSE), underscoring its crucial role in minimally invasive lung cancer diagnosis[1].

This systematic review and meta-analysis assesses the diagnostic utility and safety profile of transbronchial lung cryobiopsy for interstitial lung diseases. It concludes that cryobiopsy offers a high diagnostic yield with an acceptable safety profile, making it a valuable tool in the multidisciplinary approach to interstitial lung disease diagnosis, often minimizing the need for surgical biopsy[2].

This article discusses the pivotal role of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) in diagnosing and staging lung cancer. It emphasizes EBUS-TBNA's high sensitivity and specificity for mediastinal lymph node evaluation, thereby guiding treatment decisions and avoiding more invasive procedures for many patients[3].

Description

Interventional pulmonology employs a diverse array of advanced techniques for the diagnosis and management of various thoracic conditions. For peripheral lung lesions, navigational bronchoscopy, incorporating electromagnetic navigation and ultrathin bronchoscopy, significantly enhances diagnostic effectiveness. The yield improves further when combined with rapid on-site cytologic evaluation (ROSE), playing a crucial role in minimally invasive lung cancer diagnosis [1]. Complementing this, endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is foundational for diagnosing and staging lung cancer, particularly for evaluating mediastinal lymph nodes. Its high sensitivity and specificity often guide treatment decisions, helping many patients avoid more invasive surgical procedures [3]. Adding to diagnostic precision, robot-assisted bronchoscopy for peripheral pulmonary nodules represents a notable advancement. Robotic systems provide enhanced navigation and stability, which can improve the diagnostic yield for particularly challenging lesions located in the lung periphery [9].

Beyond localized lesions, interventional pulmonology addresses diffuse parenchymal lung diseases and pleural pathologies. Transbronchial lung cryobiopsy, for instance, offers high diagnostic utility with an acceptable safety profile for interstitial lung diseases. This technique has become a valuable component of the multidisciplinary diagnostic approach, often reducing the need for more invasive surgical biopsies [2]. For pleural diseases, medical thoracoscopy serves as both a diagnostic and therapeutic tool. It proves effective in managing malignant pleural effusions, distinguishing various exudative effusions, and performing pleurodesis, illustrating its evolving capabilities in pleural space management [4]. Furthermore, pleural manometry is instrumental in managing malignant pleural effusions by assessing pleural space dynamics during fluid drainage. This guidance ensures safe fluid removal, helps prevent re-expansion pulmonary edema, and optimizes symptom relief for patients [8].

Maintaining airway patency is another critical area. Airway stenting is a key intervention for managing benign tracheal stenosis. Reviews highlight various stent types, their specific indications, and potential complications, underscoring the necessity of individualized patient assessment and multidisciplinary care to achieve optimal outcomes [5]. Similarly, malignant airway obstruction benefits from a range of bronchoscopic thermal ablation techniques. Procedures like electrocautery, argon plasma coagulation, and laser therapy are vital for rapidly relieving dyspnea and enhancing the quality of life for individuals with advanced lung cancer [7].

In the realm of advanced respiratory care, comprehensive reviews examine bronchoscopic lung volume reduction techniques for emphysema, encompassing endobronchial valves and coils. These methods, with detailed consideration of mechanisms and patient selection, are affirmed as viable options to improve lung function and quality of life for carefully selected Chronic Obstructive Pulmonary Disease (COPD) patients [6]. Moreover, performing bronchoscopy in critically ill patients, specifically those requiring extracorporeal membrane oxygenation (ECMO), demands specialized guidelines. Expert consensus papers provide critical recommendations for safety, monitoring, and procedural adjustments to effectively conduct bronchoscopic interventions in this highly vulnerable population, ensuring necessary care without compromising patient stability [10]. These advancements collectively illustrate the breadth and impact of modern interventional pulmonology in both diagnostics and therapeutics, continually improving patient outcomes through less invasive and more targeted interventions.

Conclusion

Interventional pulmonology offers a wide array of advanced diagnostic and therapeutic techniques for various lung and pleural conditions. For diagnosing peripheral lung lesions and staging lung cancer, methods like navigational bronchoscopy, endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA), and robot-assisted bronchoscopy provide high diagnostic yields and minimize invasiveness. These techniques are crucial for accurate diagnoses and guiding treatment decisions, often enhanced by tools like rapid on-site cytologic evaluation (ROSE). In the context of diffuse lung diseases, transbronchial lung cryobiopsy offers a safe and effective diagnostic approach for interstitial lung diseases, frequently reducing the need for surgical biopsies. Pleural diseases are managed using medical thoracoscopy for both diagnosis and therapy, especially for malignant effusions and pleurodesis, with pleural manometry guiding safe fluid drainage. Therapeutic interventions focus on maintaining airway patency and relieving obstruction. Airway stenting addresses benign tracheal stenosis, while bronchoscopic thermal ablation techniques rapidly relieve malignant airway obstruction. Furthermore, procedures like bronchoscopic lung volume reduction using valves and coils are viable options for improving lung function in selected emphysema patients. Special considerations are also given to bronchoscopy in highly vulnerable populations, such as those on extracorporeal membrane oxygenation (ECMO), with guidelines ensuring safety and effectiveness. This comprehensive approach highlights the significant role of interventional pulmonology in improving patient outcomes.
