Sigmoidoscopy (Flexible Sigmoidoscopy)

Advantages of a sigmoidoscopy: 

• The test is usually quick, with few complications.
• Usually does not require sedation.
• Many primary care doctors can do the test in their office.
• Less extensive cleansing of the colon is necessary than for a colonoscopy.
• For most patients, discomfort is minimal.
• Can identify and remove polyps before they turn into cancer.
• In some cases, the doctor may be able to perform a biopsy (the removal of tissue for examination under a microscope by a pathologist) and, if necessary, remove polyps during the test.
• Moderate cost, covered by most health insurance.
• Can accurately find polyps in the lower part of the colon (where most polyps occur).
• If the results are normal, a more expensive colonoscopy will not be recommended.

Disadvantages of sigmoidoscopy: 

• This test allows the doctor to view only the rectum and the lower part of the colon. Any polyps in the upper part of the colon will be missed.
• May require enema preparation.
• Patients may find the test uncomfortable and embarrassing.
• There is a small risk of bleeding or tearing of the lining of the colon.
• Additional procedures, such as a colonoscopy, may be necessary if the test indicates an abnormality.
