There are two types of EBUS bronchoscopes available: radial catheter probe and convex probe EBUS (CP-EBUS), [37] but only the latter concerns us here. Early experience with mediastinal staging by CP-EBUS appears very promising with sensitivities ranging from 92 to 96 percent in 4 series comprising 70 to 502 patients. [38] [39] [40] [41]
The results provided a "yield/procedure [rate at] 74% and 100% for peripheral lesions and lymph nodes, respectively." Additionally, "a diagnosis was obtained in 80.4% of bronchoscopic procedures." The study concluded that ENB "is a safe method for sampling peripheral and mediastinal lesions with high diagnostic yield independent of lesion size ...
Bronchoscopy is an endoscopic technique of visualizing the inside of the airways for diagnostic and therapeutic purposes. An instrument ( bronchoscope ) is inserted into the airways, usually through the nose or mouth, or occasionally through a tracheostomy .

A lung biopsy is an interventional procedure performed to diagnose lung pathology by obtaining a small piece of lung which is examined under a microscope. [ 1 ] [ 2 ] Beyond microscopic examination for cellular morphology and architecture, special stains and cultures can be performed on the tissue obtained.
Bronchoalveolar lavage (BAL), also known as bronchoalveolar washing, is a diagnostic method of the lower respiratory system in which a bronchoscope is passed through the mouth or nose into an appropriate airway in the lungs, with a measured amount of fluid introduced and then collected for examination.
Bronchial brushing is a procedure in which cells are taken from the inside of the airway mucosa or bronchial lesions through catheter-based brushing under direct visualization or fluoroscopic guidance.
Bronchoscopy with bronchoalveolar lavage is recommended in possible cases of organizing pneumonia to rule out infection and other causes of alveolar infiltrates. [9] The bronchoalveolar lavage in organizing pneumonia shows a lymphocytic predominant inflammation of the alveoli with increases in neutrophils and eosinophils. [9]
