• Definition
    • Anoscopy is a method to look at the:

      • Anus
      • Anal canal
      • Lower rectum
  • How the Test is Performed
    • The procedure is usually done in a doctor's office.

      A digital rectal exam is done first. Then, a lubricated instrument called an anoscope is placed a few inches into the rectum. You will feel some discomfort when this is done.

      The anoscope has a light on the end, so your health care provider can see the entire area. A sample for biopsy can be taken, if needed.

  • How to Prepare for the Test
    • You may receive a laxative, enema, or other preparation before the procedure so that you can completely empty your bowel. You should empty your bladder before the procedure.

  • How the Test will Feel
    • There will be some discomfort during the procedure. You may feel the need to have a bowel movement. You may feel a pinch when a biopsy is taken.

      You can usually return to normal activities after the procedure.

  • Why the Test is Performed
    • This test may be used to determine whether you have:
