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.

Blood thinners, such as Coumadin® (warfarin) or Plavix® (clopidigrel).
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

safely do this. Contact us if you have questions.

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.

▪ Do not return to work.
▪ Do not use hazardous machinery.
▪ Do not make any important decisions.
▪ Plan to rest.
▪ Do not drink alcohol.
▪ Do not drive.
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.
