Sigmoidoscopy Vs Colonoscopy Procedure
I am considering a screening sigmoidoscopy over that of a colonoscopy due to more preparation and procedural involvement. No family history. Wise?
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
Longer test: A sigmoidoscopy only sees part of the colon. The traditional sigmoidoscopy was 60 centimeters and saw the sigmoid and descending colon. A colonoscope is 120-160cm and should visualize the entire colon. Usually the sigmoidoscopy is done unsedated while the colonoscopy is done with sedation. 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
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! Read more
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. Read more
Cost: This is variable. Would contact the facility or provider to obtain more information about the anticipated cost. Read more
I am refusing to have a colonoscopy or sigmoidoscopy unless it becomes my very last resort. What test options can I insist on in UK please possibleibs?
I am sorry: But I don't practice in the UK and I don't know health care policies in Britain. I don't know if Health Tap has any providers in the United Kingdom. All the physicians that I know in Health Tap are based in the United States. Read more
Can many months of cdif & tx make your colon more likely to perforate from colonoscopy or sigmoidoscopy after its cured (test ok & no sx)?
Depends: An inflamed colon is at higher risk of complications during colonoscopy as it tends to be thicker, more blood flow, and less flexible. If your colon has recovered from for C difficle colitis then your risk is back to normal. If you have been chronically ill and you are malnourished as a result you will have a slightly increased risk as well as a decreased ability to recover from a complication.

Does a sigmoidoscopy hurt? My doctor told me I won’t get any sedation for my sigmoidoscopy, but my friend had sedation for his colonoscopy. Does that mean a sigmoidscopy hurts less?
Less uncomfortable: Different patients have different perceptions of pain. That being said, a sigmoidoscopy is generally less uncomfortable because they insert the instrument not nearly as far as with a colonoscopy. Consequently, they don't have to expand the inside of your colon with as much air during sigmoidoscopy which is generally the uncomfortable part. Sigmoidoscopy is commonly performed without sedation.

Can the cecum be seen during a colonoscopy? Or is it through a sigmoidoscopy? Can cancer of the cecum be detected through radiology tests like ct/mri?
Yes-No-Maybe: Colonoscopy evaluates the entire large intestine, from cecum to rectum. Flexible sigmoidoscopy only goes as far as the left side of the colon, nowhere near the cecum. Routine ct scanning may identify a (large) cecal tumor but is much less sensitive than a colonoscopy; ct colonography is almost as sensitive as a colonoscopy, but is less desirable than colonoscopy since a biopsy cannot be done.

Is sigmoidoscopy enough for a 30 year old no family history of colon cancer patient with red blood covered stool or must a colonoscopy be performed?
Proctosigmoidoscopy is an examination of the rectum and sigmoid colon (just above the rectum) using a narrow, rigid scope with a built-in light. A small amount of air is usually introduced to distend the bowel, allowing for a better view. Generally, a limited prep is helpful, but not always necessary. ...Read more
