Getting Ready for Rectal Dilitation
What is a Rectal Dilitation?
A rectal dilitation is a stretching of the rectal muscle. This is sometimes needed because a tight area has developed after bowel surgery. Stretching allows stool to pass through as normal.
Important – Read 1 week in advance.
Procedure may be cancelled if instructions are not followed.
Getting Ready for a Rectal Dilitation
1. 7 days before, you should stop taking the blood thinner Effient® (prasugrel).
2. 5 days before, you should stop taking:
- Blood thinners, such as Coumadin® (warfarin) or Plavix® (clopidogrel).
3. 2 days before, you should stop taking the blood thinner Pradaxa® (dabigatran).
Blood thinning pills should never be stopped without discussing this with the doctor who prescribes it for you. The doctor will give you instructions on how to safely do this. Contact us if you have questions.
4. Diabetic medicines (oral and insulin) will need to be adjusted for the time you’re not eating as normal. Please discuss this with your local doctor.
5. You must have an adult to drive you home or your exam will be cancelled. You may take a cab or bus home only if you have a responsible adult with you other than the driver.
6. Plan ahead. For your exam you will be given sedatives which can greatly affect your judgment. On the day of your exam, you will not be able to drive or return to work. Do not make important personal or business decisons until the next day.
7. Our staff will need to review your health history, prior surgeries, allergies, and medicines taken. Please bring this information with you.

The Rectal Dilitation
A nurse will review your health history and place an IV. The IV is used to give you medicines which make you feel drowsy and relaxed during your test. The procedure will take less than 30 minutes. You will then go to our Recovery Room for about an hour. Your driver may sit with you there. Once awake, you will be given something to drink. Your doctor will discuss results with you before discharge. You and the doctor who referred you will receive a copy of the report.
After the Rectal Dilitation and for the Rest of the Day
- Do not return to work.
- Do not use hazardous machinery.
- Do not make any important decisions.
- Plan to rest.
- Do not drink alcohol.

You should be able to resume normal daily tasks on the day after your test. You may notice a small amount of rectal bleeding; this is normal. If it continues longer than 48 hours, please contact your doctor.
