Endobronchial ultrasound (EBUS) with transbronchial needle aspiration (TBNA), also known as EBUS with ROSE (rapid on-site evaluation), is a diagnostic procedure used to obtain tissue or fluid samples from the lung or surrounding lymph nodes for evaluation.
During the procedure, a bronchoscope with an ultrasound probe is passed through the mouth or nose and into the airways. The ultrasound probe allows the doctor to see the lymph nodes or other structures surrounding the airways. A fine needle is then passed through the bronchoscope and into the lymph node or tissue, and a sample is collected for analysis.
The ROSE component of the procedure involves examining the collected samples under a microscope in the procedure room by a pathologist to evaluate the adequacy of the sample, to ensure that enough tissue has been collected for accurate diagnosis. This real-time evaluation can help reduce the need for additional procedures or follow-up visits.
EBUS with ROSE is commonly used to diagnose lung cancer, as well as other conditions such as infections, sarcoidosis, and lymphoma. It is a minimally invasive procedure with a low risk of complications and can often provide a definitive diagnosis, which can help guide treatment decisions.
