Pronounced: Endo-scopic Ul-tra-sew-naw-gra-feeEn Español (Spanish Version)
Endoscopic ultrasonography (EUS) is used to view the walls of your digestive tract and other nearby organs. An ultrasound uses sound waves to make images of the inside of the body. In an EUS, the ultrasound probe is passed down the throat or up the rectum and into digestive tract.
EUS may be used to:
- Diagnose or find the cause of a pain or abnormality in the digestive tract
- Locate and view tumors or abnormalities in the pancreas, bile ducts, and chest cavity
- Understand the extent of certain cancers and whether they have spread to lymph glands or other vital organs
- Take tissue samples (biopsy) to diagnose a condition
- Provide needle aspiration (to drain a cyst)
