Instructions for rectal endoscopic ultrasound

You are scheduled for a endoscopic ultrasound. Endoscopic ultrasound (EUS) is a procedure in which your doctor will use a thin flexible tube, called and endoscope. The endoscope has a special tip that sends out waves and provides the doctor with an ultrasound picture of your digestive tract.

Please arrive 30 minutes prior to your procedure time for registration. If you are unable to keep this appointment you must cancel at least 48 hours in advance or you will be referred back to your primary care physician.

Please follow these instructions completely and carefully:

  • If you take medicine to thin your blood (heparin, coumadin, plavix, warfarin) your primary care doctor must tell you how many days before the procedure you must stop taking it. In some cases you may continue to take the medication but you must check with your doctor first.
  • If you are diabetic and using insulin or are taking oral diabetic medications, contact your primary care doctor for instructions on adjusting these medications for the day of your procedure.
  • You may take your blood pressure and heart medication as usual the morning of the procedure with a sip of water.
  • Do not take ibuprofen (Motrin), Advil, Aleve, naprosyn, aspirin or medication containing aspirin or NSAIDs (Vioxx, Celebrex) for 5 days prior to your procedure.

Your lower colon must be completely empty for the rectal EUS procedure to be thorough and safe. To prepare for the procedure you must do the following:

  • Start a clear liquid diet the day before your procedure.
  • You may have clear liquids for breakfast and lunch on the day of your procedure. Clear liquids are liquids that you can see through such as water, coffee, tea, broth, soda and Jell-O. Also, juices that are clear, like apple and white grape, Gatorade, and popsicles. NO RED COLORS.
  • Obtain 2 fleets enemas from your pharmacy. They are packaged in a green and white container and usually cost about $1.00 each.
  • Administer the enemas to yourself prior to your procedure. The first enema should be given 2 hours before your appointment and the second enema 1 hour before your procedure.
