Colonoscopy is the Gold Standard for Colorectal Cancer Screening.
It is the only way to remove polyps and take biopsies of cancers or other abnormal areas.
It is safe and effective. It could save your life!

What is a Colonoscopy?

A colonoscopy is a specialised examination where our specialist will guide a colonoscope into your anus to examine the inside of your large intestine (rectum and colon). This is done under sedation with the patient comfortably asleep and safely monitored.

What is a Colonoscope?

A colonoscope is a thin flexible tube that our specialist uses to perform the colonoscopy. Using controls at one end, he can take pictures and perform biopsies or remove polyps on the inside of the colon and rectum.

How do I prepare for Colonoscopy?

The procedure can be done in half a day without needing to stay overnight. In our practice, we offer patients the option of clearing their bowels on the same morning in the hospital instead of at home the night before! This way patients can have a good night’s rest and do all the preparation under the safe supervision of hospital staff.
The steps for preparation begin up to 1 week before, depending on your medical history.

7 days before the procedure

  • stop blood thinners (eg. Plavix)

3 days before the procedure

  • stop blood thinners (eg. aspirin)
  • no fibre (vegetables, fruits, oats, wholemeal bread, bran, etc…)
  • drink plenty of clear fluids
  • meat is fine

Our doctor and staff will provide you with more details during the consultation.
