Special Issue Information

Dear Colleagues,

Interventional pulmonology integrates advanced techniques and tools to diagnose and treat a wide range of pulmonary disorders using minimally invasive methods. Over the past few decades, interventional pulmonology has experienced an extraordinary evolution, facilitated by the integration of technological advances with the clinical decision-making process of clinicians, enabling a patient-centered diagnostic and therapeutic approach. This Special Issue aims to explore the latest technological innovations and their clinical applications within the field of interventional pulmonology. Topics of interest for publication include, but are not limited to, the role of interventional pulmonology in lung cancer screening, the diagnosis of peripheral lung nodules, mediastinal staging, airway stenting, and the potential therapeutic role of endoscopic techniques. We welcome original research and comprehensive reviews that showcase the recent advances in these areas. By highlighting recent progress, this Special Issue seeks to provide clinicians and researchers with a comprehensive overview of the current state and future potential of interventional pulmonology.

Background: Thoracic ultrasound (TUS) has emerged as a viable alternative of computed tomography (CT) for pneumothorax diagnosis. Ultrasound elastography (USE), a technique assessing tissue elasticity, has recently been proposed as a novel tool for pneumothorax evaluation. Methods: This prospective, monocentric, observational study aimed to compare the diagnostic accuracy of static and dynamic USE with TUS in detecting iatrogenic pneumothorax after CT-guided transthoracic needle aspiration (TTNA). Results: Thirty-two patients were enrolled, with pneumothorax confirmed via CT in 40.63% of cases. The results showed that elastographic-mode images had significantly higher sensitivity (76.9% vs. 21.2%, p < 0.001) and improved positive and negative predictive values (67.8% vs. 52.4%, p-value 0.01, 82.6% vs. 61.7%, p-value < 0.001, respectively), compared to B-mode images. Concordance between expert and non-expert evaluators was also higher for elastographic images, suggesting improved interpretability. However, dynamic USE did not demonstrate a statistically significant advantage over B-mode videos. Conclusions: These findings suggest that USE may enhance static ultrasound-based pneumothorax detection and provide an objective imaging marker for reports. Further multicenter studies are needed to confirm these findings and explore the potential role of USE in other settings. Full article

Background/Objectives: Fluoroscopy has been widely adopted in interventional pulmonology, as it facilitates real-time visualization of the bronchoscope, endobronchial ultrasound, and biopsy tools during procedures. The purpose of this study was to evaluate the effectiveness of radiation shields in minimizing scattered X-ray dose to the bronchoscopist in a phantom study and to determine the dose of scattered X-ray dose to medical staff with radiation shields in clinical application. Methods: An anthropomorphic torso phantom was positioned on the fluoroscopic table between the C-arm X-ray tube and the image detector to mimic bronchoscopic operations. Upper and lower body lead shields were used to examine the effectiveness of radiation shielding. Scatter radiation rates were assessed at a first operator location using real-time dosimeters with and without protective devices. In clinical application, the scattered X-ray dose of the first operator and main assistant was measured using wearable radiation dosimeters during 20 procedures. Results: In the phantom study, scattered radiation without shielding was 266.34 ± 8.86 μSv/h (glabella), 483.90 ± 8.01 μSv/h (upper thorax), 143.97 ± 8.20 μSv/h (hypogastrium), and 7.22 ± 0.28 μSv/h (ankle). The combination of upper and lower body lead shields reduced the scattered X-ray dose by 98.7%, 98.3%, 66.2%, and 79.9% at these levels, respectively. In clinical application, mean scattered X-ray dose rates were 0.14 ± 0.05 μSv/procedure (eye), 0.46 ± 0.51 μSv/procedure (chest), 0.67 ± 0.50 μSv/procedure (hypogastrium), and 1.57 ± 2.84 μSv/procedure (assistant’s wrist). Conclusions: The combination of radiation shields significantly reduced the scattered X-ray dose at the operator site in the phantom study. The scattered X-ray dose to medical staff during bronchoscopy can be kept at a low level with the aid of a shielding system. Full article

Non-expandable lung (NEL) occurs when the lung fails to fully re-expand after pleural fluid drainage, complicating management and limiting therapeutic options. Diagnosis, based on clinical symptoms, pleural manometry, and traditional imaging, is often delayed to the peri- or post-procedural stages, leading to improper management, complications, and higher healthcare costs. Therefore, early, pre-procedural diagnostic methods are needed. Thoracic ultrasound (TUS) has emerged as a non-invasive tool with the potential to enhance diagnostic accuracy and guide clinical decisions, yet, it remains inadequately studied within the context of NEL. We conducted a non-systematic narrative review using a structured methodology, including a comprehensive database search, predefined inclusion criteria, and QUADAS-2 quality assessment. This approach ensured a rigorous synthesis of evidence on TUS in NEL, with the aim of identifying knowledge gaps and guiding future studies. Non-invasive, real-time, bedside M-mode TUS has demonstrated efficacy in predicting NEL prior to thoracentesis by detecting an absent sinusoidal sign and reduced atelectatic lung movement. Emerging experimental techniques, including 2D shear wave elastography (SWE), speckle tracking imaging (STI) strain analysis, the lung/liver echogenicity (LLE) ratio, TUS assessment of dynamic air bronchograms, and pleural thickening evaluation, show additional potential to enhance pre-procedural NEL detection. However, all these methods have significant limitations that require further comprehensive investigation. Despite their significant promise, TUS modalities for early NEL detection still require rigorous validation and standardization before broad clinical use. A multimodal diagnostic approach, combining clinical manifestations, pleural manometry, radiologic and ultrasonographic findings, along with emerging techniques (once fully validated), may provide the most extensive framework for NEL. Regardless of advancements, patient-centered care and shared decision-making remain essential. Further research is needed to improve outcomes, reduce healthcare costs, and enhance long-term treatment strategies. Full article
