What is a Fissure?
An anal fissure is a crack or tear located posteriorally at the bottom of the anus. An ulcer is created by friction of the intestinal content, especially when, for reasons not always known, there is high pressure in the rectum.
The most prominent clinical manifestation of a fissure is periodic pain after defecation - the pain is sharp and is much more severe than the pain caused by hemorrhoids. Unlike with hemorrhoids, blood only appears rarely.
Fissure treatment includes novel drugs or botulinum toxin injection. The treatment is generally performed during a check-up and takes several minutes.
More severe cases require surgery, performed by a surgeon who specializes in proctology.
