Endoscopic ultrasound (EUS) is a procedure used to image the digestive tract, including the pancreas, lesions in the esophagus, and stomach. It is used to diagnose and stage cancers of the digestive tract. If necessary, your doctor may need to take samples during the procedure.

Please bring a disc of any recent radiology studies that you have had when you come in for your procedure (CT scans, MRIs, PET scans, Ultrasounds, etc.).

A responsible adult (family member or friend) must come with you to your EUS and remain in the Endoscopy Lab area until you are discharged.  You are not allowed to drive, take a taxi or bus, or leave the Endoscopy Lab alone. If you do not have a responsible adult (family member or friend) with you to take you home, your exam will be cancelled.
