Anal Fissure (cont.)

Anal Fissure Surgery

Lateral internal sphincterectomy describes the procedure where the thickened internal sphincter muscle is incised to allow it to relax by releasing the tension within the circular muscle, and allowing the fissure to heal. The operation is usually performed under general or spinal anesthesia.

Sometimes, when a chronic fissure is present, the surgeon may elect to excise or cut out the fissure at the same time.

The pain of the anal fissure resolves almost immediately post operatively. Laxatives and stool softeners may be recommended for a few days after surgery. A high fiber diet is a lifelong recommendation to prevent recurrence.
