Endoscopic Ultrasound (EUS)
A flexible tube with a camera and ultrasound built in is used to look at the patient's digestive system from the inside. The scope is approximately the size of a dime.This procedure is performed by a physician with extensive training in this specialized area. The patient is always sedated for this procedure to relax the patient and decrease the anxiety and fear. The patient is watched closely during the procedure including routine check of the blood pressure, heart rate and respiration. It can be done for either the upper or lower digestive tract. The procedure is performed for various reasons including determining a tumor's depth. Injection of medication to reduce or alleviate pain due to pancreatitis can be accomplished during this procedure, as well. The procedure can take up to 45 minutes to an hour to perform.
Usually the patient will be asked not to eat or drink anything at least 6 hours prior to the test. Most often, the physician will ask the patient not to eat or drink after midnight the night prior to the procedure. Hospital stay is usually no more than 3 hours from the time of arrival to the Endoscopy Center waiting room until completion of the procedure.
