What is a colonoscopy?

A colonoscopy is a test that allows your doctor to look at the inner lining of your large intestine - the rectum and colon. The physician uses a thin, flexible tube called a colonoscope, with a small camera attached, to look at and take pictures or video of the colon. A colonoscopy helps find ulcers, colon polyps, tumors, and areas of inflammation or bleeding. During a colonoscopy, tissue samples can be collected and abnormal growths can be taken out. A colonoscopy can also be used as a screening test to check for cancer or precancerous growths in the colon or rectum.

Accuracy of a colonoscopy is important. The Adenomatous Polyp Detection Rate or ADR Rate, is how the quality of a colonscopy exam is measured. At the MacNeal (GI) Gastroenterology Lab, the polyp detection rate is higher than the national average rates for men and women. The national standard is that a significant polyp should be removed in at least 15% of colonoscopies in women and 25% of colonoscopies in men.  Additionally, flat polyps and small polyps are more difficult to see. MacNeal’s GI Lab uses high definition and computer-enhanced endoscopy imaging to improve visibility for difficult polyps and improve polyp detection. 

Who should have a colonoscopy?

Anyone over the age of 50. Your doctor may recommend earlier or more frequent testing if you have a higher risk of colorectal cancer. Talk to your doctor about when you should be tested.
