Gregory Endoscopy Centre
Colonoscopy is a diagnostic procedure that allows the physician to examine the entire length of the large intestine. Colonoscopy can assist in identifying problems with the colon, such as early signs of cancer, inflamed tissue, ulcers and bleeding. Colonoscopy is also used to screen for colorectal cancer, the second leading cause of cancer-related deaths in the United States and the fourth most common cancer in men and women. Patients often don’t feel any symptoms during the early stages of colon cancer, but the colonoscopy can provide your doctor with visual evidence.
During the procedure a thin, flexible, lighted tube, called a colonoscope, is placed into the rectum and colon. In addition to allowing visualization of the internal colon, the colonoscope enables the physician to irrigate, suction, inject air and access the bowel with surgical instruments. During a colonoscopy, the physician may remove tissue and/or polyps for further examination and possibly treat any problems that are discovered.
Other related procedures that may be used to assess problems of the colon include abdominal x-ray, computed tomography (CT scan) of the abdomen, abdominal ultrasound, barium enema and sigmoidoscopy.

Other Printable Colonoscopy Resources:
A low-fiber diet limits the amount of food waste that has to move through the large intestine.
Please follow this diet three to five days prior to the procedure (click for PDF).
For Patients with Diabetes: Contact your primary care provider about diabetic medications. You will not be eating or drinking for a few hours before your test. Your medications may need adjustment to keep your blood sugar at a safe level.
For Patients on Blood Thinners: Medicines like Coumadin (warfarin), Pradaxa and Plavix (clopidogrel) are usually stopped 5 to 7 days before your test. Stopping them helps prevent bleeding if tissue is removed or biopsied. You must contact your primary care provider for specific directions about these medications. In some cases, you may not be able to have your test while taking blood thinners.
For Patients with Pacemakers, Defibrillators and Other Implanted Devices: Bring your device card with you. Make sure your pacemaker has had its routine checkup.
