[Anal fissure].

The anal fissure is a very common disease of the anal canal. Diagnosis is easy and most patients have a typical history of pains and anal bleeding. Proctoscopy will certify the anal fissure. The treatment is based on reducing the spastic of the internal anal sphincter, either by dilating the anal canal or sphincterotomy. Excision of the anal fissure should only be done in case of fissures with intersphincteric fistula or abscess. High fibre diet and increasing the volume of daily drinks is a useful and very efficient help in treating anal fissures.
