Flexible Bronchoscopy
Flexible bronchoscopy is a procedure to examine the breathing airways. This test lets your doctor see the inside of the airways and take tissue (a biopsy) or mucus samples. The bronchoscope is a thin tube-shaped instrument. It's inserted through the nose or mouth. A camera at the end of the tube takes images which are then sent to a video screen.
You may have a robotic-assisted bronchoscopy (also called a robotic bronchoscopy). This lets your doctor move the equipment more precisely by using a robotic controller. It helps your doctor see into hard-to-reach areas of the lungs. Also, your doctor can use a smaller tube for a robotic bronschoscopy than for a traditional bronchoscopy.

Before your test
-
Follow your doctor's instructions carefully. If you don’t, the exam may be canceled. Or you may need to take it again.
-
You might need blood tests before the procedure. Follow instructions from your care team and keep all appointments.
-
Ask your doctor if you should stop taking certain medicines before this test, especially blood-thinning medicines.
-
Follow any directions you're given for not eating or drinking before the test.
-
Don't smoke for 24 hours before the test.
-
You'll need to remove any dentures or removable devices from your mouth.
-
Right before the test, you will be given sedating medicines to help you relax. The medicine may be given by an I.V. (intravenously) into one of your veins. Also, your nose and throat may be numbed with a special spray to help prevent gagging and coughing.
-
If you are having this test as an outpatient, make sure you have an adult friend or family member drive you home.
During your test
Bronchoscopy takes 45 to 60 minutes and includes the following steps:
-
You may be given medicine (anesthesia) so that you are unconscious or asleep during the procedure.
-
The doctor puts the tube into your nose or mouth.
-
If you haven't been given anesthesia, you might have a gagging feeling. To help ease this feeling, you will be told to swallow or take deep breaths. Your airway will remain open even with the tube in place. But you won’t be able to talk.
-
The doctor checks your airway. They may also remove tiny tissue samples for a biopsy.
-
If you are having a robotic bronchoscopy, the doctor moves the tube with a robotic controller. Imaging techniques are used to help find and sample abnormal areas.
After your test
-
You may have a mild sore throat or cough. Your voice may also be hoarse.
-
Don't eat or drink until the anesthesia wears off.
-
You might see very small amounts of blood being coughed up.
