Endoscopic Ultrasound

What is Endoscopic Ultrasound?

Endoscopic ultrasound is an imaging method that uses high-frequency sound waves to produce images of the digestive system. The device is on a long flexible camera that is inserted into the mouth and passed into the stomach to exam the upper gastrointestinal tract. The camera can also be inserted into the rectum to evaluate the lower colon. This technology is very useful when evaluating the pancreas, stomach, gallbladder, esophagus and rectum. It is especially important in the evaluation of gastrointestinal cancers.

During Endoscopic Ultrasound

Prior to the procedure, you’ll receive an intravenous sedative that will make you feel sleepy and help you relax. Throughout the exam, your heart rate and blood pressure will be carefully monitored. Once the sedative has taken effect, Dr. Singh will insert a specially equipped endoscope with a small ultrasound transducer on the tip, into your mouth and down into the esophagus. From there he will examine the esophagus, stomach, intestine, and neighboring organs using the ultrasound. Dr. Singh may pump air into the stomach and intestine during the procedure. Depending on complexity (and on whether additional procedures such as a polyp removal, a biopsy or a fine needle aspiration are performed during your Endoscopic Ultrasound), the exam usually takes from 45-90 minutes.

After Endoscopic Ultrasound

You’ll be recovering for about an hour from the effects of the sedative. You will need a ride back home and some rest. You may experience some temporary discomfort. Bloating and cramps are a common reaction to the air pumped into your stomach during Endoscopic Ultrasound. If you have a sore throat, gargling with salt water will relieve it. A light meal and non-alcoholic drinks are fine after the procedure.
