Perspective

Patients with severe emphysema have few treatment options, and effective medical treatment provides just a tiny benefit. LVRS is the only alternative therapy with a significant clinical benefit in emphysaema, but due to the perceived risk and invasiveness of surgery, bronchoscopic techniques to induce lung volume decrease have grown in popularity. EBV, airway bypass operation, endobronchial coils, thermal (vapour) sclerosis, and chemical sclerosis are all bronchoscopic treatments for volume reduction in severe emphysema (sealants). Patient selection is critical to achieving positive patient outcomes. This article describes how bronchoscopic treatments for emphysema have evolved from clinical trials to clinical practise. Chronic Obstructive Pulmonary Disease (COPD) is a common and rapidly progressing illness.

Bronchoscopic Lung Volume Reduction (BLVR) procedures, which were recently developed, give customised therapy choices in subgroups of patients with severe emphysema. By causing lobar atelectasis, endobronchial and intrabronchial valves (EBV/IBV) reduce lung volume. Tissue compression is induced via Lung Volume Reduction Coils (LVRCs) and bronchoscopic Thermal Vapour Ablation (BTVA), either mechanically or by inflammatory processes. While the effects of EBV/IBV can be reversed by removing the implants, LVRC is only partially reversible, and BTVA is irreversible. Because of its method of action, the presence of interlobar Collateral Ventilation (CV) has an impact on EBV/IBV therapy outcomes. As a result, it is critical to assess CV utilising radiographic and endoscopic procedures. The current evidence for BLVR shows that it is safe and effective in the short term. However, no headto-head trials exist, and further study is needed to determine the treatments' long-term therapeutic value, durability, and cost-effectiveness.

In individuals with severe emphysema, Bronchoscopy Lung Volume Reduction (BLVR) has been shown to be beneficial. These approaches are split into two groups: non-blocking devices that do not require collateral ventilation and blocking devices that do require collateral ventilation, so selecting the target lobe with insufficient scissors is critical for treatment effectiveness. Current research suggests that BLVR will not improve all emphysema classifications and phenotypes, and that each approach appears to benefit specific sub-groups of patients. Careful patient selection is essential to avoid unnecessary spending and insertion in patients who are unlikely to benefit clinically. The Chartis system is a direct measurement method that represents the gold standard for assessing fissure integrity. The TC research, on the other hand, is an indirect method that, thanks to the advent of quantitative analytic software, allows us to acquire valid values of regional parenchymal density, airway thickness, and scissor integrity. BLVR is a substantially condensed version of BLVR.

Practical training should include discussions of clinical cases as well as insertion techniques for various devices on plastic or animal models, as well as cadavers. On the usage of Zephyr valves, a specific course with final certification has been designed. Airflow limitation, hyperinflation, and decreased gas exchange are pathophysiological features of Chronic Obstructive Pulmonary Disease (COPD), a degenerative lung illness. Lifestyle adjustments, lung rehabilitation, and pharmaceutical therapy such as LongActing Beta-2 Agonists (LABA) and long-acting muscarinic antagonists are used to treat the condition (LAMA). Bronchoscopic therapies for COPD have only lately become available. Endobronchial Valves (EBV) and Endobronchial Coils (EBC), as well as endobronchial stents, sclerosing agents, targeted lung denervation, and liquid nitrogen metered cryospray, are among the treatments available. We hope to outline the latest emerging bronchoscopic treatments as well as their effect sizes as compared to lung rehabilitation and pharmaceutical therapy in this study.

Bronchoscopic procedures for chronic obstructive pulmonary disease are beneficial additions to pharmaceutical therapy (COPD). However, various COPD phenotypes have varying clinical responses to the same or similar medication. The phenotypes must also be considered when choosing the best bronchoscopic interventions for COPD patients. Novel interventional pulmonology procedures that were applied for COPD treatments in everyday clinical practise or clinical studies, according to the distinct phenotypes. For smokers, chronic obstructive pulmonary disease (COPD) is a serious disability. At home, the majority of patients require constant oxygen therapy. Furthermore, respiratory infections are particularly common among these people, and influenza immunisation is required. Computed Tomography (CT) detects emphysema and bronchiectasis, and these parenchymal abnormalities are accountable for pneumothorax in one case and pseudomonas aeroginosa infection in another. Novel mini-invasive procedures are currently being used to treat emphysema, and they are comprehensively documented in our current work.
