Bronchoscopy and pleuroscopy are minimally invasive endoscopic procedures used to diagnose and treat lung diseases. Bronchoscopy involves inserting a thin, lighted tube with a camera through the mouth or nose into the lungs, while pleuroscopy accesses the pleural space between the lungs through a small incision in the chest. Both procedures allow doctors to directly examine the lungs and collect samples, and have benefits of providing quick results without the need for surgical cuts or long hospital stays.
