Colonoscopy

What is a Colonoscopy?

A colonoscopy is the procedure used to directly examine the inside of the bowel with the aid of a colonoscopy. This is a long thin fibre-optic instrument about the thickness of your index finger. The procedure takes about 30 minutes; the entire process may take approximately 2 hours.

It allows full color inspection of the inside of the bowel, and in most instances can provide substantially more detail and accuracy. It is also advantageous as it allows biopsy and removal of polyps to be carried out at the same time.

As colonic polyps carry a risk of cancer, it is recommended that all polyps found at the time of colonoscopy be removed. This is despite the minor risk of bleeding or perforation.

Adequate preparation is crucial

It is very important that the bowel is thoroughly emptied and cleaned for a successful colonoscopy. The adequacy of examination relies on un-obscured view of the bowel.

The bowel preparation will make you go to the toilet frequently so plan to say close to the toilet. If you have a colostomy or ileostomy, you may need to notify your stomal therapist for a special drainage bag.

What are the risks?

Colonoscopy is a very safe, but as with all medical procedures there is some risk. The sedative drugs can cause heart or lung complications. They are more likely in patients with underlying heart or lung disease.

Very rarely the colonoscope can make a hole in the bowel (1:1000 chance). Removal of polyps is associated with a risk of bleeding and slightly increased risk of making a hole in the bowel. Minor complications such as abdominal pain, dehydration and soreness at the site of the injection are more common. The risk of perforation is rare, but if it occurs, may require surgery.

Please tell your doctor if you are pregnant, or breast feeding, or have a cardiac pacemaker, or suffer from heart valve disease, or have diabetes, or take blood thinners.

AFTER THE COLONOSCOPY

When the procedure is finished you will return to the post procedure area where we will ask you to fast until the effects of the sedation have worn off. We suggest that during this time you rest on your bed and try to relax. After this time, you will be given something to eat and drink. Then you will be allowed to go home.

You must not drive a car, operate machinery or undertake any legal decisions for 24 hours after the procedure. Arrangements must be made for a friend or relative to pick you up from the hospital.

IF you have any questions about the colonoscopy or information you have just read, please ask the nursing staff or your doctor as we are more than happy to answer any questions you may have.

DISCHARGE

Should you have severe abdominal pain, bleeding from the back passage, fever or other symptoms that concern you, please contact the doctor immediately or go to your nearest hospital emergency department.

You should not plan to travel too far from medical aid for the next two weeks following the procedure as there is a risk of bleeding particularly if a polyp has been removed.

There may be some spotting of blood in the first 24 hours. This is not abnormal and not a cause for alarm. If this does NOT stop or causes concern, please seek medical attention.
