Colonoscopy
What is a colonoscopy?
A colonoscopy is a medical procedure performed by a physician (usually a gastroenterologist) to view inside your colon (large intestine) and rectum. Using a long, flexible, video camera device called a colonoscope or “scope,” the physician can visually study the lining of the colon. Because the colonoscope is flexible, it bends within the curves of your colon to allow the gastroenterologist to view specific portions of the colon’s lining. The colonoscope can also inflate air into your colon to expand the area and provide better views. The physician will likely take photos or videos during the procedure to show you results, document findings in your medical records or provide to other physicians and specialists for further evaluation.
Diverticulosis
Why is this procedure performed?
A colonoscopy can help detect indications of digestive diseases and cancer, such as inflamed tissue, ulcers, infections, and abnormal growths or polyps. Because the colonoscope allows the physician to view the inside of the colon, it is the procedure of choice to screen patients for colon cancer. A colonoscopy is recommended for most people beginning at age 50. It may be recommended for you at a younger age if you have a family history of colon or colorectal cancer.
