If it is your job to prep a patient for a colonoscopy, they may ask many questions, especially if it is their first one, or if they have to get one due to an underlying condition. A colonoscopy is a test that enables a doctor to look at the in inner lining of your large intestine, which is the rectum and colon. They use a very thin flexible tube to look at the colon, which allows the doctor to check for ulcers, colon Polyps, tumors, or inflammation and bleeding. Tissue samples may be collected and sent to a lab to check for cancer or precancerous growths. The tube is very flexible, and has a small video camera attached at the end, so that the doctor can take pictures and videos of the colon. The test allows the doctor to view the entire colon and lower part of the intestines. A colonoscopy is more complete than a sigmoidoscopy, which shows only the rectum and bottom portion of the colon.
