Facing the possibility of a health crisis—and the complicated choices in diagnostic and treatment options—can be overwhelming. The Electromagnetic Navigation Bronchoscopy (ENB) procedure is just one of many options that you and your doctors have in facing the possibility of cancer, and in making the best decisions for your specific situation.
The focus of all the technology we create is to give you and your doctor clear information to work with, as quickly and using as minimally invasive means as possible.
Why do I need a lung biopsy?
Lung biopsies are used to determine whether you have a health issue. Biopsies also provide doctors with information on your genetic characteristics.1 This information is essential to planning the next stages of your care.
How are lung lesions biopsied?
There are many options for biopsies, such as ENB procedures, bronchoscopy, transthoracic needle aspiration (TTNA) or surgical options like mediastinoscopy, thoracoscopy or a thoracotomy. Each carries its own unique risks that you should discuss with your doctor.
What is bronchoscopy?
The bronchoscopy procedure is a minimally invasive procedure that looks into the airways of your lungs using a thin lighted tube called a bronchoscope. Traditional bronchoscopy gives many doctors ways to help patients; however, this procedure does not allow doctors to reach all areas of the lung due to the size of the bronchoscope.
What is Electromagnetic Navigation Bronchoscopy (ENB)?
An ENB procedure is used when a CT scan reveals a spot in your lung that is in a location difficult to reach with traditional bronchoscopy. Many times, lung lesions are beyond the reach of the bronchoscope. ENB procedures use a navigation catheter that extends the reach of a bronchoscope. Doctors use ENB procedures to access the very farthest areas of your lung, where they will gather tissue from your lung to make a diagnosis and consider treatment options. To date, more than 70,000 patients worldwide have had an ENB procedure.2
What can I expect during an ENB procedure?
During the ENB procedure, your doctor will insert a bronchoscope through your airways and into your lungs. A bronchoscope is a lighted tube that’s about the width of a pencil. Once the tube is in place, your doctor will insert specially designed tools to take a tissue sample for testing. The procedure takes, on the average, between 30 minutes and one hour to complete3 and, for many people, can be performed on an outpatient basis with no overnight stay.
How is this different from traditional bronchoscopy?
Traditional bronchoscopy has helped many doctors aid in the diagnosis of lung cancer; however, this procedure only allows doctors to reach the center regions of the lung. The superDimension™ navigation system allows physicians access to the outermost areas of the lung while still minimizing the invasiveness and recovery time needed for a surgical diagnostic procedure.
How does the technology in the superDimension™ system work?
It works much like the Global Positioning System (GPS) in your car or phone. Using a CT scan, the superDimension™ navigation system creates a three-dimensional map of the lungs. Your doctor uses our technology and the 3D map it generates to access your lung lesion, where they can use tiny biopsy tools to take samples and prepare for any additional procedures, giving you personalized treatment options tailored to your specific case.
What is a fiducial marker?
In addition to collecting lung tissue samples during your ENB procedure, your doctor may also decide to place fiducial markers. These extremely tiny markers are placed in the lung tissue around the lesion in order to help easily locate the lesion again in case any additional procedures are necessary.
What are the risks of an ENB procedure?
The most common risk is pneumothorax (collapsed lung). However, the risk is lower compared to other conventional diagnostic procedures such as needle biopsies (including a transthoracic needle aspiration [TTNA], a CT-guided fine-needle aspiration biopsy [CTFNA], or a Transthoracic Needle Biopsy [TTNB]) and invasive procedures.*
How soon will I get my lung biopsy results?
Some doctors will have experts in the room during the ENB procedure so they can test the sample right away; others will send the sample to a lab and give you your results at a later time.
Where can I learn more?
Medtronic has partnered with patient advocates to ensure that support and information is available when you need it most. We offer a list of helpful links for more information about lung health, as well as resources for support for you and your loved ones during the path ahead.
* ENB procedures carry a pneumothorax risk of 1.6% vs. 15-42% for CT-guided TTNAs.4,5
Thoracotomy may carry a higher risk of adverse events, including pulmonary events (33% for VATS and 45% for open thoracotomy).6
