Maybe one day: There are large studies underway right now to answer that question. The US Preventative Services Task Force has not yet decided on whether the fecal DNA test is enough on its own to screen for colon cancer. ...Read more

Bowel issues 3 years, 4 Ct scans over that time with oral contrast, sigmoidoscopy to 35 cm, only diverticulosis seen, chances of missed cancer?

Bowel issues 3 years, 4 Ct scans over that time with oral contrast, sigmoidoscopy to 35 cm, only diverticulosis seen, chances of missed cancer?

Slim: in spite of the low chance of missing a cancer, a complete colonoscopy would examine the rest of the colon not visualized on sigmoidoscopy. CT is only fair to see colon cancers unless large because stool may get in the way. If you are still concerned then talking to your doctor may resolve these issues. ...Read more

Please tell me about flexible sigmoidoscopy and colonoscopy ?

Please tell me about flexible sigmoidoscopy and colonoscopy ?

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

Have Crohns. GI wants to do check-up colonscopy. Unilateral leg swelling w/ vein stick out; MRI, vein ultrasound, ABI, norm. Proceed with colonoscopy?

Have Crohns. GI wants to do check-up colonscopy. Unilateral leg swelling w/ vein stick out; MRI, vein ultrasound, ABI, norm. Proceed with colonoscopy?

Yes: Sometimes there is a microperforation with Crohns and a locatlized inflammatory process is set up where DVT occurs within the femoral or external iliac vein on the left side. This could produce the unilateral leg swelling which I assume would be on the left. If this proved to be such as on pelvic CT then anticoag and even a cava umbrella might be necessary and of course the colonoscopy. ...Read more

Dietary modification: You can try a gluten free diet. Ct scans, mri, and colonoscopy are not sensitive or specific when the symptoms are loose stools.

Diagnosed with a "tortuous colon" via oral barium CT scan & colonoscopy; have very distended abbdomen, pain, etc. What to do?

High fiber diet: The elongated colon may need help from a high fiber diet. Avoiding foods and medications that cause constipation is also important. Ask your doctor if there are other issues that may need to be addressed, as the tortuous colon may not be the explanation for your current complaints. ...Read more

66 years old. No hx of polyps or positive hematocult. Is cologuard a good idea instead of colonoscopy. Had negative virtual colonoscopy seven years ag?

66 years old. No hx of polyps or positive hematocult. Is cologuard a good idea instead of colonoscopy. Had negative virtual colonoscopy seven years ag?

Colon cancer screen: If you have never had a colonoscopy, you should. It currently is the gold standard for colon cancer screening. Cologuard and virtual colonography both have a substantially higher false negative rate. With medication, colonoscopy these days is very easy, comfortable, and safe, and will give you the highest likelihood of being able to preevent colon cancer. Don't sell yourself short! ...Read more
