Alternatives
A colonoscopy is the best method available to detect, diagnose and treat abnormalities within the colon. There are alternatives to this procedure, but these are quite limited and can only diagnose, not treat, potential problems within the colon. Options include:
Cologuard® or Fecal Immunochemical Testing (FIT)
These stool tests are for adults 45 years or older at average risk for
colon cancer and can be collected at home. These tests are not for patients
who have had certain types of
polyps in the past, a history of inflammatory bowel disease (IBD), certain hereditary
syndromes, or a personal or family history of colorectal cancer. Stool
tests are not a replacement for a colonoscopy in high-risk patients. Some
patients with a positive test will have a completely normal colonoscopy
exam; some will have polyps that can be removed; and a small percentage
will have colon cancer. Any patient who has a positive stool test should
then schedule a diagnostic colonoscopy.
Barium enema
This is an X-ray exam of the colon. A small tube is passed through the
rectum, and barium (a metallic substance) is instilled to coat the lining
of the colon. X-rays are then taken to see the soft tissues of the colon.
A colonoscopy still may be required to diagnose and treat an abnormality.
Flexible sigmoidoscopy
This is a limited examination with a scope only visualizing the last one-third
of the colon. It is only recommended if known abnormalities are located
in this area.
If you have any questions about these alternative options, talk to your primary care provider.
