How do I prepare for endoscopic ultrasonography (EUS)?

Here's a synopsis of the key things that you should do to prepare for your endoscopic ultrasound (EUS), a medical procedure to examine the lining and the walls of the upper and lower gastrointestinal tracts:

  1. Call your insurance company and ask if the endoscopic ultrasound test is covered for the reason given by your doctor.
  2. Ask your insurance company if you need a referral for the endoscopic ultrasound. If they say "yes," then you MUST get a referral from your primary care physician.
  3. Update your insurance registration.
  4. Make plans for someone to come with you to the hospital.
  5. If you take Coumadin, Plavix or other blood thinners, please talk to the doctor who prescribed it.
  6. If you are diabetic, please speak with your doctor about how to take your medication in order to prevent low blood sugar.
For endoscopic ultrasonography (EUS) of the upper gastrointestinal tract, you should have nothing to eat or drink, usually for six hours before the examination. Your doctor will tell you when to start this fasting and whether it is advisable to take your regular prescription medications. For EUS of the rectum or colon, your doctor will instruct you to either consume a colonic cleansing solution or to follow a clear liquid diet combined with laxatives or enemas prior to the examination. The procedure might have to be rescheduled if you don't follow your doctor's instructions carefully.
