(en-doh-SKAH-pik...) EUS. A procedure in which an endoscope is inserted into the body. An endoscope is a thin, tube-like instrument that has a light and a lens for viewing. A probe at the end of the endoscope is used to bounce high-energy sound waves (ultrasound) off internal organs to make a picture (sonogram). Also called endosonography.
A procedure that combines endoscopy and ultrasound and allows a doctor to obtain images and information about the digestive tract and the surrounding tissue and organs.
EUS combines ultrasound and endoscopy so that doctors can see the amount of cancer in nearby tissues.
An endoscope with an attached small ultrasound probe shows how far the cancer has grown.
Abbreviated EUS. A procedure that combines endoscopy and ultrasound to obtain images and information about the digestive tract and the surrounding tissue and organs. In EUS a small ultrasound transducer is installed on the tip of the endoscope allowing the transducer to get close to the organs inside the body so the resultant ultrasound images are often more accurate and detailed than ones obtained by traditional ultrasound.

An endoscopic procedure using ultrasound waves to detect and to biopsy abnormal areas on the wall or just outside the intestinal tract. It is often used to determine the extent of cancers in the esophagus, stomach, pancreas, and rectum.
A procedure in which an instrument using ultrasonic waves (those beyond the range of human hearing) is introduced into the digestive track. The device can detect tumors anywhere from the mouth to the colon. If a tumor is located, a fine needle is used to take a tissue sample, or biopsy, for examination by a pathologist (a physician specializing in the identification of diseases.)
Endoscopic ultrasound is medical procedure where an endoscopically directed ultrasound is used to image thoracic and abdominal viscera.
