Anal fissure is a defect in (break or tear) of the skin of anal canal. The symptoms of an anal fissure usually include pain and bleeding. An anal fissure causes a severe and sharp pain when you pass stools. Once this sharp pain has passed, it is usually replaced by a deep burning pain, which may be felt for several hours after you have been to the toilet. Anal fissures can also cause bleeding when you pass stools. Most people notice a small amount of bright red blood, either in their stools or on the toilet paper.
Nearly 90% of acute anal fissures will heal using conservative measures alone. By contrast, only 20 – 30% of chronic fissures are likely to heal by conservative therapy. There are three levels of the therapy:
- Chemical Sphincterotomy
- Botulinum Toxin
- Surgical Treatment
The recurrence rate of anal fissure after treatment ranges up to 30%. Some degree of impaired continence is observed in 11 % of patients after surgical treatment of anal fissure.
