Anoscopy

How the test is performed:

An anoscopy involves viewing the anus and anal canal.

First, the doctor performs a digital rectal exam. The doctor inserts a lubricated, gloved finger into the rectum to determine if anything will block the insertion of the scope.

The doctor then inserts a lubricated plastic anoscope a few inches into the rectum. This enlarges the rectum to allow the doctor 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 can be carefully inspected.

How to prepare for the test:

Clear your rectum of stool before the procedure. A laxative, enema, or other preparation may be administered to aid evacuation.

Infants and children:
The physical and psychological preparation you can provide for this or any test or procedure depends on your child's age, interests, previous experience, and level of trust. For specific information regarding how you can prepare your child, see the following topics as they correspond to your child's age:

• 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 a little 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 is commonly used to determine if a patient has hemorrhoids, anal polyps, inflammation, fissures, or an infection.
