Endoscopic Ultrasound
What is an Endoscopic Ultrasound? What is an Endoscopic Ultrasound?An endoscopic ultrasound exam is a visual examination of the lining of the esophagus, stomach and duodenum, combined with an ultrasound exam of the surrounding structures. How is the test performed?A lighted flexible tube with an ultrasound probe at its end is inserted through the mouth. Before the procedure, an IV will be placed in one of your arms and medication will be given to help you relax. A nurse will spray the back of your throat with a local anesthetic to stop your gag reflex and to make it easier for the lighted flexible tube to be inserted during the procedure. Your nurse will be present during the entire examination and will be monitoring you closely. Biopsies of pancreas, stomach and esophagus may be performed during the test. How do I prepare for the test?To prepare for the endoscopy, do not eat or drink anything after midnight the night before your examination. Remember, no breakfast. Please notify the nurse or doctor if you have any allergies to medications. If you have diabetes and take insulin, on the morning of your exam you should not take any regular insulin and take only half of your usual Lente or NPH insulin dose. A small amount of clear liquids can be taken in the early morning if your appointment is in the afternoon. How long will the test take?The examination takes about 1-2 hours and is performed in the Medical Procedures Unit. You should, however, plan on at least 3-4 hours, as you will be in the recovery room until you are fully awake. What happens after the test is done?Following the exam, you will be able to eat as soon as your gag reflex returns. We do require you to bring a driver or arrange transportation home after your endoscopy. Driving, operating machinery or riding a bicycle is not permitted for at least 12 hours because of drowsiness and delayed reflexes from the IV medication. Important decisions or any activity that requires you to be fully alert should not be done on the day of your test. If you are unable to keep your appointment or you have questions regarding this test, please call the Medical Procedures Unit at (734) 936-9250. |
