How is a colonoscope test done ?

How is a colonoscope test done ?

Sedation: Colonoscopy is performed by placing a long, flexible tube along the entire colon and rectum via the anus. While people dread this, it is painless when done under sedation. The worst part is the day before when the "prep" is taken to purge the system. Although unpleasant, this will find polyps before they turn into cancers, thus saving one from major surgery. If you're 50, "get 'er done". ...Read more

Had colonscopy done, notes say small AC lesion near the cecum. Had CT scan, waiting for results. Biopsy was not done. Colonscopy 2013 was clear. Idea?

Polypoid lesion: If on colonoscopy a small lesion noted in the ascending colon not seen previously I suspect a small polypoid growth noted. If base not on a stalk, bx might have been held off for possibility that bx could lead to performation. If small such lesions hard to define on scan.

Erosive gastritis. h.pylori blood test positive, breath test positive, stool antigen test negative, biopsy negative. what to do ?

Erosive gastritis. h.pylori blood test positive, breath test positive, stool antigen test negative, biopsy negative.  what to do ?

However, I am impressed by the positive breath test and erosive gastritis. I would have expected stool antigen to be positive, as it mirrors the breath test. Given the discrepant results, treat the patient. ...Read more
