16,18) A recent analysis of cancers not detected by flexible sigmoidoscopy showed that of the prevalent but not detected lesions, 37% were beyond the reach of the sigmoidoscope, while 7% were due to inadequate depth of insertion of the sigmoidoscope; 36% were due to problems in patient compliance, and 21% were due to endoscopist limitation.

Colorectal cancer screening

Similar to the flexible sigmoidoscope, the colonoscope is a longer thin black tube that allows the health care professional to examine the entire large intestine.

Colon cancer

A conscious effort and manual guidance are necessary for the sigmoidoscope to enter the diverticulum.

Proctoscopy is performed with a shorter instrument than sigmoidoscope and is not recommended as a colorectal cancer screening test.

A shorter version of the colonoscope is called a sigmoidoscope.

What is Colonoscopy?

The flexible sigmoidoscope permits fairly complete examination of the colon and increases patient tolerance and comfort.

Making a difference in cancer prevention

Because the sigmoidoscope only visualizes the lower third of the intestine, the entire colon must then be examined with a colonoscope if a polyp is found.
