Endobronchial Ultrasound (EBUS)

Endobronchial ultrasound (EBUS) is a relatively new procedure used in the diagnosis of lung cancer, lung infections, and other diseases causing enlarged lymph nodes or masses in the chest. Currently, Delta Medix is proud to be one of the few centers in Northeastern Pennsylvania to offer EBUS, a minimally invasive procedure that has proven highly effective.

EBUS is a minimally invasive procedure, so patients can have it on an outpatient basis. It is proven to be highly effective. This new technology allows physicians to sample central lung masses and lymph nodes with the help of ultrasound guidance. Our physicians are able to get good biopsies without creating too much discomfort for the patient. 

Why is it used?

  • The EBUS procedure allows physicians to perform a technique known as transbronchial needle aspiration (TBNA) to obtain tissue or fluid samples from the lungs and surrounding lymph nodes without conventional surgery. The samples can be used for diagnosing and staging lung cancer, detecting infections, and identifying inflammatory diseases that affect the lungs, such as sarcoidosis or other cancers like lymphoma.

What makes EBUS different?

During the conventional diagnostic procedure, a surgical procedure known as mediastinoscopy is performed to provide access to the chest. A small incision is made in the neck just above the breastbone or next to the breastbone. Next, a thin scope, called a mediastinoscope, is inserted through the opening to provide access to the lungs and surrounding lymph nodes. Tissue or fluid is then collected via biopsy.
During an endobronchial ultrasound:

  • The physician can perform needle aspiration on lymph nodes using a bronchoscope inserted through the mouth
  • A special endoscope fitted with an ultrasound processor and a fine-gauge aspiration needle is guided through the patient’s trachea
  • There are no incisions are necessary with the EBUS procedure

Benefits of EBUS

  • Provides real-time imaging of the surface of the airways, blood vessels, lungs, and lymph nodes
  • The improved images allow the physician to easily view difficult-to-reach areas and to access more, and smaller, lymph nodes for biopsy with the aspiration needle than through conventional mediatinoscopy
  • The accuracy and speed of the EBUS procedure lends itself to rapid onsite pathologic evaluation Pathologists in the operating room can process and examine biopsy samples as they are obtained and can request additional samples to be taken immediately if needed
  • EBUS is performed under moderate sedation or general anesthesia
  • Patients recover quickly and can generally go home the same day
