| 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 metal or 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 is 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: A child's age and previous experience determine which steps are appropriate to prepare a child for this procedure. For specific recommendations, refer to 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 may be used to determine if a patient has hemorrhoids , anal polyps, inflammation, fissures, or an infection. |
| Normal Values | The anal canal appears normal in size, color, and tone. There is no evidence of bleeding , polyps, hemorrhoids, or other abnormal tissue. |
| What abnormal results mean | This test may be done to determine if a patient has hemorrhoids , an abscess , inflammation, infection, fissures, or polyps (benign or malignant). |
| What the risks are | There are minimal risks for simple anoscopy. If a biopsy is needed, there is a limited risk of bleeding and mild pain. |
