Why Is A Flexible Sigmoidoscopy Done Instead Of A Colonoscopy
Sigmoidoscopy is the use of a flexible fiberoptic camera or specially designed scope to examine the inside of the colon. Because the procedure only examines the left side of the colon (in an area called the sigmoid), it is termed sigmoidoscopy. This is to differentiate it from a colonoscopy, where the entire right and left side of the colon is examined. A sigmoidoscopy ...Read more
Two separate procedu: These are two separate procedures for checking the large intestine. Sigmoidoscope is shorter and can look inside about one half of the( lower) colon. Colonoscopy is done with a colonoscope, which is much longer and can go up all the way into the entire colon and check it out for any internal disease of the colon like cancer or polyps. ...Read more

Proctosigmoidoscopy is an examination of the rectum and sigmoid colon (just above the rectum) using a narrow, rigid scope with a built-in light.
