Endobronchial Ultrasound (EBUS)
EBUS is a minimally invasive but highly effective procedure used to diagnose lung cancer, infections, and other diseases causing enlarged lymph nodes in the chest.
Why is it used?
EBUS 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 surgery 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(EBUS):
- 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
- No incisions are necessary
Benefits of EBUS
- It 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 mediastinoscopy.
- 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 usually go home the same day
Super Dimension Navigation System (SuperD) Computer Aided Navigation
Super Dimension Navigation System (SuperD) Computer Aided Navigation is a minimally invasive but highly effective procedure using a bronchoscope and computer generated images and special radial probe ultrasound to guide instruments into abnormal areas of the lung for accurate sampling such as for possible lung cancer. This technology allows physicians to navigate and access difficult-to-reach areas of the lungs from the inside.
Why is Computer Aided Navigation used?
Significant advancement is designed to aid in the diagnosis of lung cancer and other lung problems and overcomes limitations of traditional diagnostic approaches including bronchoscopy using only flouroscopy, needle biopsy and surgery. The system guides physicians through the complicated web of pathways inside the lungs, so that they’re able to access and sample target tissue throughout the entire lung without surgery or a needle biopsy.
What makes Computer Aided Navigation Different?
Traditional bronchoscopy typically allows access only to the center regions of the lung. Using Computer Aided Navigation is specialized so a physician can navigate to the outer areas of the lung during a procedure.
Because Computer Aided Navigation Bronchoscopy biopsy is performed as an outpatient procedure, there are additional benefits, including:
- No hospital stay
- Reduced risk of complications
- Faster recovery time
Benefits of Computer Aided Navigation
- Earlier evaluation of lung lesions
- Provide a prompt and accurate diagnosis of benign and malignant lung lesions
- Determine tumor size and extent (stage)
- Avoid the need for higher risk procedures
