An anoscopy is a procedure in which a small tube is inserted
into the anus. This allows a doctor to see the inside of the anus and anal canal.
Who is a candidate for the test?
An anoscopy may be ordered for persons who have pain in the
rectum or anus. It can be ordered if the person's doctor suspects
or other problems in the anus. The test may also be done to check for
which are abnormal openings between the anus and the skin.
How is the test performed?
The doctor first does a digital rectal exam.
This is done by inserting a lubricated, gloved finger into the rectum. The
anoscope is a tube-shaped optical device designed just for this test. It has
a light that lets the doctor see inside the anal canal. If an abnormal area is
seen, a piece of tissue can be removed for testing in the laboratory. This
small sample of tissue is called a biopsy.
