Anoscopy is a method to view the anus, anal canal, and lower rectum.
The procedure is usually done in a doctor's office.
A digital rectal exam is done first. Then, a lubricated instrument (anoscope) is placed a few inches into the rectum. You will feel some discomfort when this is done.

You may receive a laxative, enema, or other preparation before the procedure so that you can completely empty your bowels. You should empty your bladder before the procedure.
