EBUS and ENB Testing

Endobronchial Ultrasound (EBUS) is an exam performed to help diagnose problems in lymph nodes, nodules or a mass in the lung. A thin scope called an EBUS is pass through your airways into your chest. The EBUS has  a light with camera and an ultrasound at its tip. The ultrasound finds the lymph nodes, nodule or mass and a needle is used to obtain a biopsy. Multiple lymph nodes may be biopsied during this procedure.

Navigational Bronchoscopy (ENB) enables your doctor to obtain biopsy samples from a lung nodule that is beyond the reach of EBUS or traditional Bronchoscopy. It has a lower risk for complications and is less invasive than an open surgical biopsy or CT-guided biopsy. It also allows the doctor to place markers, if needed, to use as targets for radiation therapy. ENB is often used in conjunction with EBUS.

Your procedure should take 2-2.5 hours. After the procedure, you’ll go to the recovery room and usually will go home the same day.

Important Note:  you must have someone to drive you home after the procedure.

An anesthesiologist will sedate you and you will have a tube placed into your airways to help you breathe. Being deeply sedated for this procedure makes it more comfortable for you and it allows the doctor to obtain good biopsy samples.
