What is a colonoscopy?

Colonoscopy is an examination of the lining of the large intestine (colon) by means of a colonoscope. A colonoscope is a long flexible tube with a tiny video camera on the end. This is passed through the anus and around the colon, enabling the lining of the colon to be directly visualised on a video screen.

Why would I need a colonoscopy?

Colonoscopy may be recommended to:

  • Look for causes of blood loss from the bowel
  • Check for polyps
  • Determine the extent and severity of any inflammation of the colon
  • Re-examine the colon after a polyp or cancer has been removed to check that no new growths have developed

How do I get a referral?

Your GP can refer you for a colonoscopy or you may contact Intus directly to make an appointment.

Common Questions

Where is a colonoscopy performed?

We perform your colonoscopy in a calm, private environment in a procedure room at Intus. Our aim is to create a relaxed clinical environment for this procedure where we have brought together the skills and experience of a leading specialists with the most advanced technology and well trained nursing staff to provide you with quality and efficiency.

Will I be anaesthetised?

Colonoscopy is sometimes uncomfortable, but rarely painful and General Anaesthesia is usually not necessary. Some people prefer not to have any sedation medication for this procedure, however light sedation with a relaxant and/or a pain killer is always available. Our goal is to keep you comfortable at all times and to ensure that the experience is not too unpleasant.

What preparation is involved for a colonoscopy and how long afterwards will I be able to resume normal activities?

A colonoscopy requires a low residue diet 2 days prior, clear fluids for all or part of the day prior, as well as a bowel preparation drink to clear the colon.

If the procedure has been performed under sedation or general anaesthesia, recovery usually takes up to two hours, after which time you will be able to eat or drink as you wish. You will not be able to drive for 24 hours following a general anaesthetic or sedation.

If you have not had any sedation or anaesthesia, you will be able to go home within 30 minutes – we recommend that you stay for a drink and something to eat before you leave – and you can carry on with your usual activities.

You should be able to resume normal activities the day after your procedure. However, you will not be able to drive for 24 hours following a general anaesthetic or sedation.

A written report is provided by your clinician after the procedure (with a copy to your GP) and further advice or diagnostic consultation are arranged as necessary.
