Colonoscopy
What is a Colonoscopy?
Colonoscopy is a procedure that enables your doctor to examine the lining of the colon, also known as the large intestine. Colonoscopy is typically done to screen for colon polyps and colon cancer or to search for an explanation of symptoms (e.g. rectal bleeding or diarrhea). An instrument known as a colonoscope, a flexible tube about the thickness of your little finger, is used by the colonoscopy doctor during the colon examination.
There is a light source and camera on the end of the colonoscope; the image is projected onto a video screen. Polyps can be removed with the colonoscope (colon polypectomy) and biopsies (tissue samples) can also be obtained.

In preparation for a colonoscopy, a colon prep or cleansing solution is administered prior to the procedure to clear the colon of all fecal matter in order to optimally visualize the lining of the colon. Intravenous medication is administered during the colonoscopy to ensure a painless experience.
