Colonoscopy

Colonoscopy. This exam allows your doctor to view your entire colon using a thin, flexible, lighted tube with a camera at the end. During the procedure, your doctor can also take small samples of tissue (biopsy) for laboratory analysis. A biopsy is the way to make the diagnosis of IBD versus other forms of inflammation.

1) What is a colonoscopy?

A colonoscopy can also be called a ‘colonoscopy’. A long flexible tube (colonoscope) is inserted into your rectum and slowly moved up into the colon. You are given medication to ease the discomfort. The colonoscope sends a picture of the inside of your colon to a video screen. A doctor examines the inside of the colon and may remove polyps using small instruments that are passed through the colonoscope. For most people, the colonoscopy goes smoothly.

Sometimes a repeat colonoscopy is needed. If this is the case, we will make the appointments for you. The specialist will follow up any abnormalities detected by the colonoscopy.

2) Where do I go to get a colonoscopy?

The programme nurse will make an appointment for you at your nearest regional hospital. The procedure is done on an outpatient basis by a qualified specialist. You will be sent instructions on how to prepare for a colonoscopy.

3) How do I prepare for a colonoscopy?

In order for the specialist to properly examine the inside of the colon, the colon must be empty. You will therefore be asked to take a strong laxative to cleanse the colon the day before and the day of the procedure. You will need to buy the laxative at the pharmacy and the programme nurse will explain how to take it. In addition, you will not be able to eat solid food the day before the procedure but you will be able to drink clear liquids.

4) What happens after a colonoscopy?

– Expect to spend two to three hours in hospital. The procedure takes about 20-45 minutes.
– Bring a list of your medications with you.
– You will be closely monitored before, during and after the procedure.
– The doctor will give you the results of the procedure and tell you if you will be seen again afterwards.
– If the colonoscopy is normal or negative, you will be invited to have another FIT in 10 years.
– If the doctor has removed polyps, he or she will give you the results of the tests when they are known (in about two to three weeks) and discuss with you the possibility of returning to the programme or the need for follow-up with different tests.
– Have an adult drive you home. You cannot drive until the next day.
– You may want to sleep when you get home. It is recommended that you do not operate equipment, sign legal documents or take alcohol until the next day.
– A responsible adult must stay with you for 24 hours after the colonoscopy.
– Unless your specialist advises otherwise, you may resume your diet and medication after the colonoscopy.
– The air that has been blown into your colon may give you gas and cramps during the procedure and afterwards. It is important to relax and pass gas as soon as possible. If the pain increases or persists, go to the emergency room and tell them that you have had a colonoscopy.
