An anal fissure is a small lesion that resembles a small, painful wound in the anus causing bleeding with bowel movements. In rare cases the anal fissure does not heal on its own or with medical treatment, or causes too much pain, in which case surgical intervention is necessary. The operation is performed under local or general anesthetic, and consists of cutting a small number of muscular fibers in the anal sphincter, at the fissure area, thus reducing the pressure applied around the fissure by the muscle and allowing it to heal. A common complication of this operation is a consequent anal incontinence during the few days following surgery.
