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.

The anoscope has a light on the end, so the health care provider can see the entire anal canal. A specimen for biopsy can be taken if needed.

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.

There will be some discomfort during the procedure, and you may feel the need to have a bowel movement. You may feel a pinch when a biopsy is taken. You can usually return to normal activities after the procedure.

This test may be used to determine whether you have:

• Anal fissues
• Anal polyps
• Hemorrhoids
• Infection
• Inflammation
• Tumors
