What is it like to have a flexible sigmoidoscopy or a colonoscopy ?

Depends!: Very few physicians perform sigmoidoscopy anymore (only checks half the colon and no sedation!). Colonoscopy is usually done with sedation or anesthesia. The procedure itself is usually not uncomfortable. The cleaning out preparation can be arduous. Colonoscopy is 50 times more life saving than a mammogram!

'Flex sig' ='cramps': For a 'flex sig' you are usually awake with no anesthesia unless arranged ahead of time with your doctor/G.I. Doctor . The pain/cramps you experience is from the air placed in the lower colon so we can see the entire bowel wall . The usual indications for flex sig are for follow-up for known proctitis (colitis) otherwise a full colonoscopy is the best test for colon cancer screening.

Both look at: The lower colon but the colonoscopy looks at the entire colon. Preps are different, colonoscopy usually requires sedation and thus someone to drive home, but flex sig can be done in office without sedation and you can resume normal activity right away. Indication are different for each so it depends on the reason you are having the exam in the first place.

Screening: A flex-sig is usually done in the office as a preliminary screening procedure. It is also useful as a follow-up if you have had polyps removed in the lower colon. Is is also useful to re-evaluate colitis and you response to treatment.

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.
