What is a Colonoscopy?

Colonoscopy is a way to look at the inside of the colon or lower bowel with a flexible tube called a colonoscope.  The scope has a light and a camera in it.  This allows the doctor to view the inside of the colon to find disease processes which do not show on x-ray examination.

During the test a polyp may be found.  Polyps are abnormal growths of tissue which vary in size. They can be removed during the colonoscopy.  This is called a polypectomy.  Polyps are usually removed because they can cause rectal bleeding or may become cancer.

  • A colonoscopy is similar to a sigmoidoscopy, but the entire colon can be viewed.
  • Mild sedation is usually used during a colonoscopy.
  • Sometimes, CT scans are used as an alternative to a regular colonoscopy. This is called a virtual colonoscopy.

Other tests:

  • Double-contrast barium enema is a special x-ray of the large intestine that looks at the colon and rectum
  • Capsule endoscopy involves swallowing a small, pill-sized camera. It is being studied, but it is not recommended for standard screening at this time.

How to Prepare for a Colonoscopy

Proper preparation is very important for this test. The colon must be clean and empty for the doctor to do the test.  Your doctor will give you a prescription for a medication called COLYTE, GOLYTELY OR NULYTELY.  This will be used to cleanse your bowels.

Contact Your Primary Care Provider for the Following:

  • Regarding any changes or what medication should be taken on the test day.
  • If you are taking any BLOOD THINNER MEDICATIONS such as Coumadin, Heparin, Ticlid or Plavix, these may or may not be stopped before your test.
  • Please talk to your doctor about any medicine changes.
  • Diabetic Patients: Ask your doctor about diabetic medications for day before and day of the test. Please check your blood sugar before arriving for the test.
