Anoscopy

Definition:

An anoscopy is a procedure that enables a physician to view the anus, anal canal, and lower rectum using a speculum.

How the test is performed:

First, the health care provider performs a digital rectal exam by inserting a lubricated, gloved finger into the rectum to determine if anything will block the insertion of the scope.

He or she then inserts a lubricated metal or plastic anoscope a few inches into the rectum. This enlarges the rectum to allow the health care provider to view the entire anal canal using a light. A specimen for biopsy can be taken if needed. As the scope is slowly removed, the lining of the anal canal is carefully inspected.

How to prepare for the test:

You will be asked to defecate to clear your rectum of stool before the procedure. A laxative, enema, or other preparation may be administered to help clear your rectum.

Infants and children:

A child's age and experience determine which steps are appropriate to help prepare him or her for this procedure. For specific recommendations, refer to the following topics:

Infant test or procedure preparation (birth to 1 year)
Toddler test or procedure preparation (1 to 3 years)
Preschooler test or procedure preparation (3 to 6 years)
Schoolage test or procedure preparation (6 to 12 years)
Adolescent test or procedure preparation (12 to 18 years)

How the test will feel:

There will be some pressure during the procedure, and you may feel the need to defecate. If biopsies are taken, you may feel a pinch.

Why the test is performed:

This test may be used to determine whether you have hemorrhoids, anal polyps, tumors, inflammation, fissures, or infection.
