Anal FissureAnal Fissure is one of the most common pathologies of the anus. An Anal Fissure is a small tear in the tissue inside the anal margin of the anal canal, and although small ( usually less than 1cm), it is very painful and can cause a sphincter muscle spasm that may last several hours.
Anal Fissure can affect people of any age (it is the most common cause for anal bleeding in children) but it is most commonly found in young adults. It affects both genders equally and is usually located posteriorly on the midline of the anus (The 6 o´clock position).
It is not yet clear what actually causes an anal fissure, but it is known that trauma to the anal canal due to constipation and the passing of hard stool is often the triggering factor. Small anal fissures may heal spontaneously but some persist and become chronic. It is believed that fissures tend to persist in people that have an inner sphichter muscle that is more contracted ( higher anal pressure )than that of people whose fissures heal spontaneously.
In our Practice we see many patients that have been treated elsewhere for their fisssures but without success: Nitroglycerine ointments, anaesthetic injections around the fissure, botulinum toxin, stool regulators and other treatments seldom lead to healing of the fissure, but are often recommended instead of surgery, for fear of anal incontinence.
