An anoscopy is a simple medical procedure that can help your doctor identify an abnormality in your gastrointestinal tract, notable in your anus and rectum.

To perform an anoscopy, your doctor will insert a device called an anoscope into your anus. This scope is typically made of plastic (disposable) or stainless steel (sterilizable). An anoscope allows your doctor to get a detailed look at the tissue within your anal-rectal areas.

An anoscopy can identify several conditions and diseases that can affect the lower part of your intestines. These include cancer, tears in the tissue called anal fissures, hemorrhoids (swollen veins around the anus and/or rectum), and rectal polyps.
