Colonoscopy

Colonoscopy is used to visually examine the wall of the large intestine (colon). Dr. Bagnato uses this technique when patients complain of symptoms such as abdominal pain, rectal bleeding, or unexplained weight loss. Using colonoscopy, Dr. Bagnato can see inflamed tissue, abnormal growths, or ulcers. He can also detect early signs of cancer in the colon and rectum.

The Colonoscopy Procedure

A colonoscope is a thin, flexible tube 5 to 6 feet in length with a small video camera attached to the front end. It sends images from the inside of the colon to a video screen where Dr. Bagnato can view the colon lining. A colonoscope can be used to look at the whole colon. A different procedure, known as a sigmoidoscopy, uses a similar but shorter scope to examine only the rectum and the lower part of the colon.

A few days before your procedure, Dr. Bagnato will give you detailed instructions on how to prepare for the colonoscopy. The preparation is necessary to make sure that your colon is empty at the time of the exam so that Dr. Bagnato's view will not be obstructed.

To prepare for the procedure, you will need to consume a diet of clear liquids for a day or two beforehand and drink a liquid that will help clean out any residual materials from your colon. Most people agree that the colon prep procedure is more difficult than the actual colonoscopy. We will give you tips and guidance to make the prep as comfortable as possible.

What to Expect During the Colonoscopy

During the exam, Dr. Bagnato will have you lie on your left side with your knees drawn up toward your chest. You will be given a sedative to relax you and pain medication to ease any discomfort.

Dr. Bagnato will insert the colonoscope through your anus and gently advance it until it reaches the lower part of the small intestine. He may ask you to occasionally shift your position to help with the advancement of the scope.

Air will be gently blown into the intestine through the scope to allow Dr. Bagnato a better view. Tissue samples may be taken during the procedure or small polyps may be removed if they are found.

Because of the sedative administered during a colonoscopy, most patients do not remember the procedure at all.
