Colonoscopy is a diagnostic test that lets your doctor look at the interior lining of your large intestine (your colon and rectum) through a thin, flexible viewing instrument called a colonoscope.
Colonoscopy is useful for identifying and removing colon polyps and also for detecting colon cancer, diverticular disease, and colitis. Colonoscopy can also be used as a screening test (colon screening) to identify and remove precancerous and/or precanerous growths in the colon or rectum. During colonoscopy, a lighted flexible instrument is inserted through the entire length of the colon. This allows direct visualization of the inner lining of the colon for diagnostic therapeutic purposes.
Colonoscopy is performed in our office where there is a facility designed for this procedure. Full sedation is given to facilitate a painless and easily accomplished procedure. A cleansing period (laxative) is required before the examination to clear the colon for full visualization. Polyp removal, biopsy, or stool culture may be performed at the time of the procedure. Colonoscopy is a safe procedure. Complications are rare but possible. There is a small chance of bleeding, injury to the bowel wall, or reactions to sedation or bowel preparation. The procedure takes approximately 25 minutes.
