Infrared Coagulation (IRC) Therapy
The Infrared Coagulator (IRC) is a special instrument that delivers heat to destroy the tissue so it can be removed. The IRC was approved by the US Food and Drug Administration for treating Condyloma (warts), hemorrhoids, chronic rhinitis and tattoo removal. Now, it is used to treat internal and external anal low grade squamous intraepithelial lesions (LSIL) and high grade squamous intraepithelial lesions (HSIL). The procedure takes place in the office with minimal discomfort during and after the treatment.
Lidocaine gel (numbing medicine) will be applied before treatment. High resolution anoscopy (HRA) will be performed to locate the abnormal areas and additional local anesthetic (numbing medicine) will be injected in the areas to be treated. The IRC tip will be placed in direct contact with the abnormal area and deliver heat for 1.5 seconds. This will be repeated as necessary to treat all of the abnormal areas of the anus. You may feel some heat from the IRC. The resulting necrotic (dead) tissue will be removed. Treatment can take up to 1 hour.
Lesions are usually treated in one office visit. Additional treatment may be required for larger lesions.
After the Procedure
Recovery is fast. Avoid lifting anything more than 20 pounds for 1 week after the procedure. Avoid inserting anything into the anus for 2 weeks after the procedure (No anal sex. No toys.).
Call the office or go to your local emergency room if you develop severe pain, heavy bleeding, or fever of more than 101 degrees.
Follow up exam
A follow up exam is scheduled 3 months after the procedure.
