What is the risk of bowel perforation from CT colonography "virtual colonoscopy"??

What is the risk of bowel perforation from CT colonography "virtual colonoscopy"??

Not invasive.: A traditional colonoscopy is invasive; the fiber optic camera is passed through the colon, and therein causes the low risk of perforation of the colon. A CT colonography is not invasive; it's just a fancier CT scan, so there's nothing to directly cause a perforation. ...Read more

Can the camera pill detect ulcerative colitis? I want to avoid doing a traditional colonoscopy.

Can the camera pill detect ulcerative colitis?  I want to avoid doing a traditional colonoscopy.

Well yes, but...: Finding that your colon is inflamed by capsule endoscopy does not MAKE a diagnosis of ulcerative colitis. The distribution of colitis, biopsy findings, IBD markers, as well as ruling out infection & ischemia are all important parts of the diagnosis. If you have UC you will likely need repeated colonoscopy surveillance with histology. Get a GI doctor who hears & can address your expressed concerns. ...Read more

Returning : Returning to the er is unlikely to help make the diagnosis. Er's are set up for emergency situations, and they cannot perform complicated testing as you know. The best thing is to establish with an excellent primary care physician, either an internal medicine or family practice physician. However, you need to know that there are some conditions that cannot be diagnosed by current technology, and it is a matter of managing the symptoms. While that is a frustrating situation, it is reality, and is something to consider as you go through this process. ...Read more

What is a colonoscopy?

What is a colonoscopy?

Look inside colon: You are sedated (very sleepy, but still breathing on your own). The endoscopist places an instrument through your anus and then passes it into the colon to carefully exam the colon for polyps, cancer, etc. If any abnormalities are found a biopsy may be done. Typically, it is painless - the only bother is cleaning out your bowels beforehand and even that's not so bad. ...Read more
