I myself phoned Wash., DC and spoke to a person in the VA health care subcommittee, and they told me they are fully aware of this issue with the dental services. The directors of all the hospitals are fully aware of this issue and frustrated on what to do. Sadly, I am not sure what to do.
A colonoscopy (koe-lun-OS-kuh-pee) is an exam used to detect changes or abnormalities in the large intestine (colon) and rectum. During a colonoscopy, a long, flexible tube (colonoscope) is inserted into the rectum. A tiny video camera at the tip of the tube allows the doctor to view the inside of the entire colon. If necessary, polyps or other types of abnormal tissue can be removed through the scope during a colonoscopy. Tissue samples (biopsies) can be taken during a colonoscopy as well.
What Is a Colonoscopy? During a colonoscopy, your doctor uses a thin, flexible camera to check for abnormalities or disease in your lower intestine or colon. The colon is the lowest portion of the gastrointestinal tract that takes in food, absorbs nutrients, and disposes of waste. The colon is attached to the anus via the rectum. The anus is the opening in your body where feces are expelled. During a colonoscopy, your doctor may also take tissue samples for biopsy. They may also remove abnormal tissue such as polyps.
