Frequently Asked Questions

Q.1.What is Colonoscopy?

Colonoscopy is a procedure that enables a physician (usually a gastroenterologist) to directly image and examine the entire colon. It is effective in the diagnosis and/or evaluation of various GI disorders (e.g. colon polyps, colon cancer, diverticulosis, inflammatory bowel disease, bleeding, change in bowel habits, abdominal pain, obstruction, and abnormal x-rays or CT scans) as well as in providing therapy (for example, removal of polyps or control of bleeding). It is also used for screening for colon cancer. A key advantage of this technique is that it allows both imaging of abnormal findings and also therapy or removal of these lesions during the same examination. This procedure is particularly helpful for the identification and removal of precancerous polyps.

Yes, there are alternative methods to examine the colon, but none are considered more accurate at colon cancer and polyp detection than colonoscopy. They include:

Flexible sigmoidoscopy and a barium enema

Computerized tomography (CT), a test that takes pictures of the inside of the colon, can also be done. This is called CT colonography or “virtual colonoscopy”. Like conventional colonoscopy, this test requires a full preparation the day before the exam (liquids and possibly enemas). This test, however, involves radiation exposure which may increase your long-term risk of developing of cancer.

If any of the above tests suggest the presence of polyps or cancer, a conventional colonoscopy (and a second preparation) will be required.

Fecal Occult Blood Testing (FOBT), is a test whereby stool is examined for minute amounts of blood loss (possibly from polyps or cancer) by way of a chemical reaction resulting in a color change. While FOBT is not a test to examine the colon, it is recommended annually to individuals over age 50. If occult blood is found in the stool, a follow-up colonoscopy will be necessary.

For colon cancer screening, it should be noted that colonoscopy has the highest sensitivity and is the only test that is both diagnostic and therapeutic.

If you have no colorectal symptoms, family history of colon cancer, polyps or inflammatory bowel disease you should have your first exam at age 50 whether you are a man or a woman since colon cancer affects both EQUALLY!

If one or more first-degree relatives has had a precancerous polyp or colon cancer, the general guideline is to begin colon cancer screening 10 years younger than the youngest age of the family member with colon cancer, or age 40, whichever is younger. There are additional guidelines for suspected or confirmed rare syndromes, and you should discuss these options with your doctor.

For patients with ulcerative colitis involving the entire colon and patients with Crohn’s disease, screening for colon cancer should begin 8 – 10 years after the initial diagnosis is made.

No, colonoscopy is usually not painful! Almost all colonoscopies can be performed using “intravenous sedation” or “twilight sedation” in which you are very drowsy but comfortable and still breathing on your own. The most common type of sedation also has a mild amnesiac effect, so most patients do not even remember the procedure! Your doctor can discuss with you the best form of sedation to suit your needs.
