This particular examination is a specialized procedure performed by a Charleston Gastroenterology physician, which combines endoscopy and ultrasound in order to obtain images and information about the digestive tract and the surrounding tissue and organs. EUS is a test that can help determine staging for various cancers within the GI tract. The information gained is very vital to the surgeon and oncologist for determining the proper treatment plan for their patients.

Your Charleston Gastroenterology Center physician can use EUS to diagnose the cause of such conditions as abdominal pain or abnormal weight loss. Or, it can be used to evaluate an abnormality, such as a growth, that was detected on a prior endoscopy or by x-ray. It allows your Charleston Gastroenterology Center physician to examine the lining and the walls of your upper and lower gastrointestinal tract which consists of the esophagus, stomach and duodenum. The lower tract includes your colon and rectum. EUS is also used to study internal organs that lie next to the gastrointestinal tract, such as the gallbladder and pancreas. Because you will be sedated, you will need someone to drive you home from the hospital.

Preparing for the Procedure

Your Charleston Gastroenterology Center nurse or doctor will provide you with preparation instructions before the examination.

What to Expect

Before the test begins your Charleston Gastroenterology Center doctor may spray your throat with a local anesthetic. Sedatives will be administered to help you relax. You’ll begin by lying on your left side, and then after the sedatives begin to work your doctor will pass the ultrasound endoscope through your mouth, esophagus and stomach into the duodenum. The instrument does not interfere with breathing and the examination takes around 15 to 45 minutes.

Afterwards

Most likely you received sedatives, so you won’t be allowed to drive after the procedure. So be sure to arrange for a ride home. It is also advised that after the examination you have someone stay with you at home. The sedatives could affect your judgment and reflexes for the rest of the day. If you had an upper EUS, your throat might be sore, and you might feel bloated due to the air and water that were introduced during the examination. Unless you’re instructed otherwise, you’ll be able to eat after you leave the procedure area. Your doctor generally can inform you of the results of the procedure that day, but the results of some tests will take longer.
