Abstract

By definition, an anal fissure is a linear tear, usually painful, in the anoderm. Acute anal fissures are generally limited to the mucosa, while chronic anal fissures may extend into the submucosa and expose the internal anal sphincter (IAS). Chronic anal fissures may develop into anal ulcers and are usually associated with a sentinel pile, or skin tag. The majority of anal fissures occur in the posterior midline in both sexes (approximately 85%-90%), although anterior-based fissures occur more commonly in females (1).
