FAQs

Q?

What is a colonoscopy procedure?

A.

Colonoscopy is the visual examination of the inner surface of the intestinal tract via means of an endoscope. A long flexible tube (colonoscope), about the thickness of a finger, is inserted into the rectum and advanced along the length of the large bowel (colon). The scope contains a video camera that produces a magnified image of the lining of the large bowel to a TV screen.

Colonoscopy is commonly used for removal of colonic polyps, to identify abnormalities (including cancers), to coagulate bleeding sites, to obtain biopsies, and for other diagnostic purposes.

What can I expect during the Flex Sig procedure?

A.

The procedure itself will take about 15-20 minutes. However please allow for 2 hours at the clinic for pre and post operative assessments.

An intravenous (IV) will be started so that the doctor can give you sedating medication to make you feel relaxed and sleepy.

Q?

What can I expect during the procedure? (colonoscopy)

A.

The procedure itself will take 20-30 minutes. However, please allow for 2 hours at the clinic for pre and post procedure assessments.

An intravenous (IV) will be started so that the doctor can give you sedating medication to make you feel relaxed and sleepy. You may be awake during the procedure but will be unlikely to remember specific details. You may feel uncomfortable for short periods of time during the test because air is used to inflate the bowel.

There is a 1:1000 chance of perforation and a 1:100 chance of bleeding (up to 10 days later) if a polyp is removed. There is a < 5% chance of missing a sizable polyp or significant lesion (the risks are higher if your bowel is not cleaned adequately).

Q?

What is an EGD

A.

An EGD (sometimes called a gastroscopy) is the visual examination of the esopohagus and stomach using an endoscope.

To prepare for the EGD procedure your mouth will be sprayed with a local anaesthetic spray. If the spray is not sufficient, then sedation will be used intravenously. A small tube will be inserted into the back of your mouth and will be manually guided into the back of the throat.

You will then be asked to make a swallow and pass the tube down. At this point a plastic guard will be placed between your teeth to protect the delicate tube. The test will take no more than five minutes or so. If a narrow spot is found in the esophagus, it will be necessary to pass a rubber tube to stretch out the narrow spot. This is called dilatation. If a growth or unusual area is seen, biopsies may be required, but this is totally painless.
