An anal fissure is an incision or tears in the anus (the opening through which the stool passes through the body) that extends into the anal canal. A fissure is a common disease of the anus. They also affect men and women, young and old. Fissure usually cause pain in the stool, which is often severe. Redness is the most common cause of rectal bleeding in early childhood. Colon fissures appear in a special tissue that covers the anus and an incision called the anoderm. Prescription drugs used to treat anal fissures that fail to heal with less conservative treatment are ointments containing anesthetics, steroids, nitroglycerin, and calcium channel blocking drugs.
