What is the best way to screen?
Colonoscopy is the most accurate test to detect colon polyps and colon cancer. However, you may have heard of alternative colon screening tests. CT colography is a second best alternative, but if polyps are found, the patient will need to undergo colonoscopy in order to remove and perform the biopsy. Flex sigs are inadequate because they only evaluate one third of the colon, where colonoscopy allows the physician to view the entire colon. Barium enemas are inadequate because they cannot detect small polyps, and fecal occult blood tests often result in a large number of false positive and false negative results.
How do I proceed with getting a test?
Contact your primary physician for a referral or call Minnesota Gastroenterology at 612-871-1145 to schedule a procedure.
What is a colonoscopy?
A colonoscopy is the most accurate test to detect colon polyps and colon cancer, and the only test where polyps can be removed during this single procedure. During this procedure a gastroenterologist examines the lining of your large intestine through a flexible tube called a colonoscope. During the procedure you will be given medicine through an IV line to help you relax; you may experience a feeling of pressure, bloating or mild cramping during and after your procedure. If abnormal tissue or polyps are found, the doctor may remove them through the colonosocope for closer examination. If biopsies are taken you will be notified of the results and next steps within a few days of the procedure.
What will be involved in having this test done?
To produce the best and most accurate results, your colon must be completely clean. A special diet will need to be followed several days prior to your procedure. You will need to go to the pharmacy and pick up the bowel cleansing preparation. As instructed, you will drink the special bowel cleansing preparation to help clean out your colon. Be sure to check the instructions given to you for this cleansing. It may require you to stay close to bathroom facilities during your cleansing period.
What if they find something?
Most polyps can be removed during the colonoscopy procedure for closer examination. If a cancer is found, a referral will be made to a surgeon or oncologist. If nothing is found and you are not in a high risk category, you will be asked to return in 5-10 years. Remember, colon cancer, when detected early, is 90% curable.
What is the cost of the test?
Most insurers cover colonoscopy even if a flex sig has already been performed. Please contact your insurer for more information about potential out of pocket expenses. The cost of the exam can vary from physician group to physician group. In addition to the physician charge, there is a charge for the colonoscopy from the hospital or ambulatory center - this cost can vary as much as $1,000. Be sure to check with your insurance company to identify the out-of-pocket cost.
