About Your Appointment

A responsible adult will need to drive you home. Taxis, Ubers, buses, medical ride services, or walking are not options unless a responsible adult accompanies you. You will not be able to drive for the rest of the day.

Plan on being at our facility for about 1 1⁄2 hours from arrival to departure (although this may vary depending on the day/procedure/location – ex. approx. 2.5 hrs for MMC)

For appointments with a scheduled arrival time of 4:00 pm or later, have your ride plan to be at the facility no later than 5:30 pm.

If you are unable to keep your appointment, please call at least 3 business days prior to your procedure to reschedule. We reserve the right to charge a penalty fee for patients who “no show” or cancel without adequate notice.


  • Aside from the medications below, we recommend you take all home medications as usual with a small amount of water, at least 3 hours before your arrival time.

Tips

If you start to feel nauseous while prepping, try:

  • Pause drinking the prep until the feeling improves, then resume
  • Decrease the amount you drink at a time
  • Take more time between drinks
  • Refrigerate the prep mixture
  • Use a straw

Prep goal: your stool should be clear and yellow. This chart will help you judge your progress!

Your prep is one of the most important parts of your ileoscopy. Without a good prep—your bowel is empty and clear—your gastroenterologist will not be able to see your colon clearly. This could lead to missing a polyp or having to reschedule your ileoscopy.


What are the risks of an Ileoscopy?

Ileoscopies are standard medical procedures. Although rare, and like will all procedures, ileoscopies have some risks:

  1. The instrument may tear the wall of the colon which may require surgery to repair.
  2. There may be adverse drug reactions or heart/breathing complications.
  3. Bleeding may occur and is more often a risk when tissue or polyps are removed.
  4. There may be discomfort during and after the procedure.

Do you have questions? Contact our office at 207-773-7964.
Office is open 8:30 am – 4:30 pm Monday – Friday
