High-Resolution Anoscopy (HRA)

High-Resolution Anoscopy is a procedure that is used to examine and evaluate the anal canal for abnormal cells or lesions that have a high likelihood of turning into cancer.  High-resolution anoscopy is performed with magnification (enlarging the apparent size not the physical size, of something).  High-resolution anoscopy has been shown to reduce the risk of anal cancer.  In addition, to the anoscope, which helps keep the anus open, a doctor uses another device called a colposcope.  A colposcope is a high-resolution mobile microscope which provides the magnification to view the area.  A doctor uses the colposcope to closely examine suspicious areas in the anal canal.

To better view the suspicious areas, the physician applies acetic acid (similar to a mild, vinegar-like solution) to a cotton swab which is then applied into the anus through the anoscope.  The acid reacts with certain abnormal cells which makes them appear white.

If any abnormal cells are detected during the exam, local anesthetic (lidocaine or similar) is used during the procedure to reduce discomfort, a biopsy (a small sample of tissue) of the abnormal tissue is performed by the surgeon.  The cells/tissue removed during the biopsy will then be sent to a laboratory for further examination under a microscope by a pathologist to confirm any cell changes.

High-resolution anoscopy are performed at a hospital or outpatient facility under sedation (similar to a colonoscopy) and local anesthesia.  High-resolution anoscopy typically takes 20-30 minutes to perform.  If a biopsy is obtained, some light bleeding and discomfort should be expected for one to two days.
