What is a Colonoscopy?
A colonoscopy is an examination of the lining of the rectum and colon (the large intestine) through a flexible tube called a colonoscope. This allows a specially trained doctor to directly view this area and identify, biopsy, or remove any abnormalities such as polyps. Removal of polyps helps to prevent colon cancer.
- Any stool that is left in the colon can hide polyps and small cancers and result in the need to repeat the colonoscopy. Therefore, it is critical that you follow your physician's instructions as directed. To make sure your colon is as clean as possible before your test, it is very important to follow the colonoscopy preparation instructions.
- You will be given sedation for the procedure. For your safety, you must arrange for a responsible adult to escort you home after the procedure. If you do not have an escort at the time of your procedure, your procedure will be canceled.
- If you are planning to take a bus, taxi or paratransit home from your procedure, you must have someone with you other than the driver. If you do not have an escort at the time of your procedure, your procedure will be canceled.
