Sydney Colonoscopy

Colonoscopy is more precise than an X-ray. This procedure also allows other instruments to be passed through the colonoscope. These may be used, for example, to painlessly remove a suspicious-looking growth/lesion/polyp or to take a biopsy (a small piece for further analysis). Colonoscopy may help to avoid surgery or to better define what type of surgery may be needed in the future.

Colonoscopy is an important way to check for colon cancer and to treat colon polyps – abnormal growths on the inside lining of the intestine. Polyps vary in size and shape and, while most are not cancerous, some may turn into cancer. However, it is not possible to tell just by looking at a polyp if it is malignant or potentially malignant. This is why colonoscopy is often used to remove polyps, a technique called a polypectomy.

Before the procedure, you will receive instructions about bowel preparation and fasting. It is important to follow these instructions carefully because the bowel needs to be adequately cleansed so that the lining can be examined clearly.

At the time of the procedure, you will receive sedation. The colonoscope is then carefully passed through the rectum and around the colon while the gastroenterologist examines the bowel lining.

If a polyp or abnormal area is found, it may be removed or biopsied during the procedure. These tissue samples can then be sent to a laboratory for examination.

The colonoscopy itself generally does not take long, although the total time at the endoscopy unit will be longer because of preparation, sedation and recovery.

A colonoscopy has a strict diet that must be followed prior to procedure. A pharmaceutical product will also be given to ensure clear images are seen throughout your procedure. Sydney Gastroenterology and Liver Group will give you further information upon confirmation of your procedure.

Please advise us of all medications prior to your procedure.

You will receive sedatives so you won’t be allowed to drive after the procedure until the next day, even if you don’t feel tired. You should arrange for a ride home. You must have someone stay with you at home after the examination as the sedatives could affect your judgment and reflexes for 24 hours.
