Endoscopic Options for Moderate COPD, Chronic Bronchitis, and Uncontrolled Asthma.
Until now, interventional therapies for patients with chronic obstructive pulmonary disease have been available in the form of lung volume reduction procedures as end-stage options. Currently, the range of indications is expanding to include earlier stages of the diseases. Lung denervation is available for moderate COPD, and patients with chronic bronchitis are being evaluated for endoscopic goblet cell ablation. ⋯ In addition to thermoplasty as a long-proven procedure, new and currently under investigation is the targeted lung denervation. Most of these techniques are currently being tested in large pivotal trials and it will soon become clear in which phenotype which technique will be used in the different forms and stages of obstructive diseases. The current paper presents the techniques and the currently available literature.

ReviewTransbronchial Lung Cryobiopsy for Diffuse Parenchymal Lung Disease.
Transbronchial lung cryobiopsy (TBLC) offers a minimally invasive option for the diagnosis of diffuse parenchymal lung diseases, of which interstitial lung diseases comprise the most common diagnoses. It has a high diagnostic yield with prognostic and therapeutic implications. ⋯ However, TBLC techniques remain variable. Here we review the latest techniques described to maximize diagnostic yield and mitigate complications of TBLC as well as how this modality has been incorporated into guidelines.

Malignant central airway obstruction (MCAO) is a debilitating and life-limiting complication that occurs in an unfortunately large number of individuals with advanced intrathoracic cancer. Although the management of MCAO is multimodal and interdisciplinary, the task of providing patients with prompt palliation falls increasingly on the shoulders of interventional pulmonologists. ⋯ That said, the spectrum of interventions for MCAO continues to expand, even if at a less impressive clip. Herein, we present on MCAO and its endoscopic and nonendoscopic management-that which is old, that which is new, and that which is still on the horizon.

Interventional Pulmonology and the Esophagus: Tracheostomy and Percutaneous Endoscopic Gastrostomy Placement.
Tracheostomy is a procedure commonly performed in intensive care units (ICU) for patients who are unable to be weaned from mechanical ventilation. Both percutaneous and surgical techniques have been validated and are chosen based on the local expertise available. ⋯ This decreases the need for additional sedation, interruption of anticoagulation, repeat transfusion, and coordination of care between multiple services. In the context of COVID-19, combined tracheostomy and gastrostomy placement exposes less health care providers overall and minimizes transportation needs.

Multicenter StudyNonmalignant Central Airway Obstruction: Options for Challenging Cases.
Benign central airway obstruction is commonly referred as nonmalignant central airway obstruction (NMCAO). This is in part related to its lack of benign nature and significant life-quality impairment in patients. It is a pathologic entity with various etiologies and therefore a wide range of therapeutic options are available. ⋯ The lack of a common pathophysiologic pathway translating into a nonspecific symptom presenting as NMCAO has complicated treatment standardization and subsequently limited solid research to favor of one approach over another one. Our intent is to describe the limited evidence of the most utilized nonsurgical treatment for NMCAO as well as some upcoming promising therapeutic options such as mitomycin C injection, microdebrider, biodegradable stents, radiotherapy, Hybrid Knife, and endoluminal spray cryotherapy. Our goal with this manuscript is to motivate other authors to venture into prospective, multicenter, open-label trials aimed to describe long-term outcomes in patients with NMCAO.
