Background: The poor treatment outcomes of multidrug-resistant tuberculosis (TB) and the emergence of extensively drug-resistant TB and extremely and totally drug-resistant TB highlight the urgent need for new antituberculous drugs and other adjuvant treatment approaches. Objectives: We have treated cavitary tuberculosis by the application of endobronchial one-way valves (Zephyr®; Pulmonx Inc., Redwood City, Calif., USA) to induce lobar volume reduction as an adjunct to drug treatment. This report describes the feasibility, effectiveness and safety of the procedure. Methods: Patients with severe lung destruction, one or more cavities or those who were ineligible for surgical resection and showed an unsatisfactory response to standard drug treatments were enrolled. During bronchoscopy, endobronchial valves were implanted in the lobar or segmental bronchi in order to induce atelectasis and reduce the cavity size. Results: Four TB patients and 1 patient with atypical mycobacteriosis were treated. The mean patient age was 52.6 years. Complete cavity collapses were observed on CT scans in 4 of the 5 cases. All patients showed improvements in their clinical status, and sputum smears became negative within 3-5 months. There were no severe short- or long-term complications. The valves were removed in 3 of the 5 patients after 8 months on average; there was no relapse after 15 months of follow-up. Conclusion: These data suggest that endobronchial valves are likely to be useful adjuncts to the treatment of therapeutically difficult patients. More data are required to confirm our findings.

Interventional pulmonology (IP) is experiencing a rapid evolution of new technologies. There is a need to develop structured training programs, organized in high volume expert centers in order to improve trainee education, and including the development of validated metrics for their competency assessment. Concerning teaching methods, a gradual progression from theory to practice, using new teaching techniques, including live sessions and low and high-fidelity simulation, flipped classroom models and problem-based learning (PBL) exercises would provide a training setting more suitable for our current need to improve skills and update professionals. Training programs should be learner-centered and competence-oriented, as well as being based on a spiral-shaped approach in which the same subject is addressed many times, from new and different perspectives of knowledge, ability, behavior and attitude, until the trainee has demonstrated a high degree of skill and professionalism. Furthermore there is a need to standardize the training programs as guide for physicians wishing to undertake a gradual and voluntary improvement of their own competencies, and assist those planning and organizing training programs in IP. The article includes a general part on core curriculum contents, innovative training methods and simulation, and introduces the following articles on the skills that the Interventional Pulmonologist must master in order to perform the different procedures. This monography should be considered a starting point that will evolve over time and results in better training for practitioners and better care for our patients. The task of establishing a trainee's competence to practice independently as an Interventional Pulmonologist remains the responsibility of the IP fellowship program director and faculty, who validate logbooks and assess competence for each procedure. These standards need to be reviewed and approved by national and International Scientific Societies and Healthcare Institutions with the aim to improve, disseminate and incorporate them in healthcare programs.

We describe the current knowledge and skills for the main techniques of operative bronchoscopy and their applications in the treatment of malignant and benign central airway disorders. Rigid bronchoscopy has a history of over 100 years. The use of rigid bronchoscopy was abandoned upon the introduction of the fiberoptic bronchoscope but has made a reappearance with the development of interventional pulmonology in the late nineteenth and early twentieth century. The advantages of rigid bronchoscopy include allowing simultaneous procedures, such as ablation, debulking and suctioning, without limiting ventilation but at the moment there are no standard approaches to perform the procedure. Rigid bronchoscopy also plays a vital role in stent placement, repositioning, maintenance and removal. An interventional pulmonology practice should only be developed when there is a locoregional unmet medical need and when a dedicated interventional pulmonology unit can be guaranteed. These departments should be available 7 days a week and should provide a fast and appropriate response to referrals in emergency cases. There is a clear need to define a competency-based training program for rigid bronchoscopy, including stent placement. An optimal, multimodality training program for bronchoscopy should include didactic lectures, web-based learning, case-based reviews and hands-on training.

Background: Amid the Coronavirus Disease 2019 (COVID-19) pandemic, the benefits and risks of bronchoscopy remain uncertain. This study was designed to characterize bronchoscopy-related practice patterns, diagnostic yields, and adverse events involving patients with known or suspected COVID-19. Methods: An online survey tool retrospectively queried bronchoscopists about their experiences with patients with known or suspected COVID-19 between March 20 and August 20, 2020. Collected data comprised the Global Pandemic SARS-CoV-2 Bronchoscopy Database (GPS-BD). All bronchoscopists and patients were anonymous with no direct investigator-to-respondent contact. Results: Bronchoscopy procedures involving 289 patients from 26 countries were analyzed. One-half of patients had known COVID-19. Most (82%) had at least 1 pre-existing comorbidity, 80% had at least 1 organ failure, 51% were critically ill, and 37% were intubated at the time of the procedure. Bronchoscopy was performed with diagnostic intent in 166 (57%) patients, yielding a diagnosis in 86 (52%). and management changes in 80 (48%). Bronchoscopy was performed with therapeutic intent in 71 (25%) patients, mostly for secretion clearance (87%). Complications attributed to bronchoscopy or significant clinical decline within 12 hours of the procedure occurred in 24 (8%) cases, with 1 death. Conclusion: Results from this international database provide a widely generalizable characterization of the benefits and risks of bronchoscopy in patients with known or suspected COVID-19. Bronchoscopy in this setting has reasonable clinical benefit, with diagnosis and/or management change resulting from about half of the diagnostic cases. However, it is not without risk, especially in patients with limited physiological reserve.
