Sigmoidoscopy (Definition)

Sigmoidoscopy is the use of a flexible fiberoptic camera or specially designed scope to examine the inside of the colon.

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?

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. ...Read more
