The test can assess how deeply a tumor penetrates your organs and the extent of any present cancer and its spread. The endoscopic ultrasound also helps the doctors get a better view of abnormalities that appear on imaging tests.
The endoscopic ultrasound can also be used to guide the drainage of cysts and the delivery of medication.
What happens during an endoscopic ultrasound?
An endoscopic ultrasound uses high-frequency sound waves to create images of the insides of your digestive tract and chest. It also allows the doctors to see nearby organs, including the liver, pancreas, and lymph nodes.
You’re given a mild sedative to help you relax for the ultrasound. During the procedure, the doctor slides an endoscope through your mouth and threads it through your digestive tract. This endoscope is a thin, flexible tube with a small ultrasound wand affixed to it.
As the sound waves bounce off your tissues, they communicate back to a computer monitor that uses them to form an image of your internal workings.
What is a fine-needle aspiration?
How do I prepare for my endoscopic ultrasound and recovery?
The entire procedure takes about an hour. Prior to your appointment, you need to fast for at least six hours and stop taking certain medications, such as blood thinners. The team at Digestive Disease Consultants of Orange County gives you thorough pre-procedure instructions.
Because you will be sedated for the procedure, you need to arrange for someone to drive you home after the ultrasound. You may choose to rest for the remainder of the day following your procedure. Side effects or complications due to the procedure are rare.
