World Association for Bronchology and Interventional Pulmonology (WABIP) guidelines on airway stenting for malignant central airway obstruction.

Malignant Central Airway Obstruction (MCAO) encompasses significant and symptomatic narrowing of the central airways that can occur due to primary lung cancer or metastatic disease. Therapeutic bronchoscopy is associated with high technical success and symptomatic relief and includes a wide range of airway interventions including airway stents. Published literature suggests that stenting practices vary significantly across the world primarily due to lack of guidance.

Central Airway Obstruction: Benign Strictures, Tracheobronchomalacia, and Malignancy-related Obstruction.

The purpose of this article is to provide an update on methods for palliating symptoms in patients with histologically benign and malignant central airway obstruction. We review the published literature within the past decade on postintubation, posttracheostomy, and TB- and transplant-related airway strictures; tracheobronchomalacia; and malignant airway obstruction. We review terminology, classification systems, and parameters that impact treatment decisions.
