Minimally Invasive Lung Biopsy with the Ion System

Robotic bronchoscopy for minimally invasive lung biopsy as an option for patients

What is a lung biopsy?

If your doctor recommends a lung biopsy to examine an abnormal growth (tumor or nodule), there may be more than one way to perform your biopsy. Traditional options include:

  • Open lung biopsy, which is surgery to remove some or all of the nodule for lab examination. Surgical biopsies typically require general anesthesia, an incision, and possibly moving ribs to get to the lungs.1 Lung surgery typically requires a hospital stay.2
  • CT-guided needle biopsy, where doctors insert needles through the skin and chest wall, puncturing the lung to reach the nodule being tested. Needle biopsies are generally done in an outpatient setting. Doctors use local anesthesia to numb the area and may also give you a sedative for relaxation.3
  • Manual bronchoscopy, which is inserting a flexible tube (catheter) with a camera. The catheter, about the size of a drink straw or larger, is inserted through your mouth and into your lung. Using images on a screen, your doctor manually guides the catheter to the nodule and extends a tool or needle to remove tissue samples. Doctors use local anesthesia to relax the throat muscles and may also give you a sedative for relaxation.4

Biopsy with the Ion system

The Ion endoluminal system is robotic-assisted bronchoscopy for minimally invasive biopsy. As with conventional bronchoscopy, your doctor inserts a catheter through your mouth to your lungs. Ion replaces bronchoscopy’s thick catheter and manual guidance with an ultrathin catheter, GPS-like navigation, and robotic assistance. This gives your doctor a stable, steerable system that can even travel through tiny, winding airways in the lungs’ outer edges.

Once at the nodule, your doctor guides the system to carefully remove a small amount of tissue from the nodule. Being able to collect tissue from small nodules anywhere in the lungs may help your doctor detect lung cancer at an earlier stage. Biopsies with the Ion system require general anesthesia and are generally performed as an outpatient procedure.

While it’s common to feel anxious before a lung biopsy, it may help to know that most lung nodules are not cancer. A lung biopsy may help put your mind at ease. If it is cancer, a lung biopsy might help your doctor diagnose it at an early stage.5

Talk to your doctor

Be sure to talk to your doctor about the outcomes they deliver using the Ion system, as every physician’s experience is different. For example, ask about:

  • Complication rate
  • Success of reaching small nodules in difficult-to-reach locations
  • How often they get a diagnosis based on the biopsy sample

In addition, you can find out what to expect on the day of your lung biopsy. Ask your doctor about planning, preparation, and recovery.
