Colonoscopy
What is colonoscopy?
Colonoscopy is a safe, effective method of examining the full lining of the colon and rectum, using a long, flexible, tubular instrument.
Who should have a colonoscopy?
Colonoscopy is routinely recommended to adults 50 years of age or older as part of a colorectal cancer screening program. A colonoscopy may be necessary to:
- Check unexplained abdominal symptoms
- Check inflammatory bowel disease (colitis)
- Verify findings of polyps or tumors located with a barium enema exam
How is colonoscopy performed?
The colonoscope is inserted into the rectum and is advanced to the portion of the colon where the small intestine joins the colon. During a complete examination of the bowel, your physician will remove polyps or take biopsies as necessary.
