Advances in bronchoscopy--therapeutic bronchoscopy.

The common indications for therapeutic bronchoscopy include relief of benign and malignant airway stenosis, in the intensive care unit, foreign body removal and management of hemoptysis. Debulking of airway tumors may be undertaken using techniques such as laser photoresection, electrocautery, cryotherapy, argon plasma coagulation or mechanically using rigid bronchoscopy. These techniques are often used in combination. Balloon dilatation and insertion of silicone or metallic airway stents can be undertaken to treat benign and malignant strictures or bronchomalacia. Airway stents maintain luminal patency by opposing extrinsic compressive forces or by providing internal support. Certain stent types may also physically prevent (Silicone and covered metallic stents) the encroachment of tumor tissue into the airways. Covered metallic airway stents are safe and effective in the management of malignant tracheoesophageal fistulae, reduce the risk of recurrent aspiration and provide enhanced quality of life by allowing resumption of oral nutrition. In this article, we present an overview of application and the current methods available to perform therapeutic bronchoscopy.
