Endoscopic Ultrasound (EUS)

Endoscopic ultrasound (EUS), which combines the flexibility of an endoscope with the high-quality images of ultrasound, and can be used to diagnose and treat many problems of the pancreas, bile duct, esophagus, stomach and colon.

Paul Yeaton, M.D., chief of Carilion Clinic Gastroenterology is recognized for performing and teaching advanced endoscopic techniques, such as endoscopic ultrasounds (EUS). He also specializes in performing advanced endoscopic examinations of the colon and stomach, which includes non-surgical management of large lesions and polyps of the stomach, duodenum, and colon.

PREPARATION

For EUS of the upper gastrointestinal tract, you should have nothing to eat or drink, usually for six hours before the examination. Your doctor will tell you when to start fasting and whether it is advisable to take your regular prescription medications.

For EUS of the rectum or colon, your doctor will instruct you to either consume a colonic cleansing solution or to follow a clear liquid diet combined with laxatives or enemas prior to the examination. The procedure might have to be rescheduled if you don't follow your doctor's instructions carefully.

DURING THE EUS

Most often you will receive sedatives intravenously to help you relax. You will most likely begin by lying on your left side. After you receive sedatives, our gastroenterologists will pass the ultrasound endoscope through your mouth, esophagus and stomach into the duodenum. The instrument does not interfere with your ability to breathe.
