Interventional pulmonary services involve a subset of diagnostic and therapeutic procedures that are usually beyond the realm of traditional bronchoscopy. PSOT offers a variety of different interventional therapies including endobronchial brachytherapy, photodynamic therapy, endobronchial laser therapy, endobronchial ultrasound, stenting and thoracoscopy. Many of these procedures are designed for the treatment of lung cancer, although benign diseases may benefit as well.
Endobronchial brachytherapy involves insertion of a catheter into the airway to offer endobronchial radiation, which uses high-dose radiation to a very limited area to control disease locally, such as in an airway. This primarily is for palliation. Similar therapy, photodynamic therapy, involves administration of a photosensitizer prior to a low energy laser therapy given into the airway using a bronchoscope, which is to kill cancer cells in the airway and to improve airway caliber. Endobronchial laser therapy, in a similar fashion, is used at a higher energy to help destroy endobronchial tumor to widen the airways. Endobronchial stents are used to prop open the airways when being compressed by cancer or benign causes.
