Ultrasound-guided transbronchial cryobiopsy of mediastinal and hilar lesions: a multicenter pragmatic cohort study with real-world evidence.

Background: Limited data exist on the reliability, efficacy and safety of ultrasound-guided transbronchial cryobiopsy for suspicious mediastinal and hilar lesions. This study shares findings from implementing this method and compares the results with those of the standard endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA).

Methods: Patients undergoing diagnostic bronchoscopy for mediastinal or hilar lesions in four Swiss centres were included.

3D printed drug-eluting stents: Toward personalized therapy for airway stenosis.

Airway stents are life-saving medical devices used to treat malignant or benign central airway stenoses. Unfortunately, these devices, typically manufactured from silicone alone and/or nitinol, can result in serious complications, such as stent migration, bacterial colonization, and tissue granulation, eventually forcing stent removal. Customized airway stents exhibit reduced migration and they can be tailored to address other complications by releasing drugs, such as the antibiotic levofloxacin and the antifibrotic drug nintedanib.

Molecular and functional landscape of malignant serous effusions for precision oncology.

Personalized treatment for patients with advanced solid tumors critically depends on the deep characterization of tumor cells from patient biopsies. Here, we comprehensively characterize a pan-cancer cohort of 150 malignant serous effusion (MSE) samples at the cellular, molecular, and functional level. We find that MSE-derived cancer cells retain the genomic and transcriptomic profiles of their corresponding primary tumors, validating their use as a patient-relevant model system for solid tumor biology.

The Use of Bronchial Rheoplasty in Emphysema Patients Previously Treated with Endoscopic Lung Volume Reduction: A Case Series.

Endoscopic lung volume reduction (ELVR) is an established treatment option for patients with severe emphysema. Not all patients are candidates for this type of intervention, and in the context of significant airway secretions, they may be excluded from treatment. Bronchial Rheoplasty (BR) was developed to treat mucus hypersecretion by delivering nonthermal pulsed electric fields to the airway epithelium and submucosa.

Successful Bronchoscopic Lung Volume Reduction with New Lung Tensioning Device Coil: A Case Report.

Introduction: Bronchoscopic lung volume reduction (BLVR) using endobronchial coil treatment is a widely studied therapeutic option in patients with end-stage chronic obstructive pulmonary disease (COPD) and pulmonary emphysema. However, patient responses were inconsistent, and, from 2020, production discontinuation rendered the treatment unavailable. In the meantime, a next-generation lung tensioning coil (FreeFlow Coil 4; FreeFlow Medical, Inc.
