Excision Fissure in Ano

Symptoms

Symptoms of an Anal Fissure

Tears in the skin cause pain and the underlying muscle goes into spasm, this tightens the anus even further, causing more pain and discomfort when attempting to open the bowels. Pain and irritation caused by fissures can last several hours after bowel opening.

Fissures are often associated with some bright red bleeding when opening the bowels this is usually seen on the toilet paper but occasionally in the toilet as well.

Investigations

How is an Anal Fissure Investigated?

The surgeon will take a full history and carry out a clinical examination. Usually this will involve a rigid sigmoidoscopy and sometimes a proctoscopy as well. If the area is too uncomfortable to examine then the consultant may recommend carrying out an examination under anaesthetic.

If you are over the age of 40 and have had any bleeding or change in bowel habit the doctor may recommend endoscopic examination of the bowel either by flexible sigmoidoscopy or colonoscopy to ensure that it is otherwise healthy, alongside treating the fissure.

Treatment

Anal Fissure Treatment

Most fissures can be treated without the need for surgery. With small, shallow anal fissures patients are advised to keep their stools soft and to avoid straining. This can be helped by taking a high fibre diet with plenty of fluids. The use of stool softeners can help. Warm baths and careful personal hygiene, especially after a bowel movement, can help to relieve pain and irritation. Some patients benefit from using haemorrhoid preparations either bought over-the-counter or prescribed by the doctor.

Fissures that do not respond to the simple measures above can be treated with creams that are specifically designed to relax the anal muscle and improve blood flow to allow healing. The creams used are GTN (rectogesic) or Diltiazem (Anoheal). Both can cause headaches and need to be used for at least 2 months to ensure healing.

Some fissures don't respond to specialist creams. Botulinum Toxin (Bot Tox) has been used to bring about relaxation in the muscle. This involves a simple injection. Although now widely used Botulinum Toxin is not specifically licensed for treatment of fissures. Sometimes Botulinum Toxin injection can relax the muscles so much that patients can experience some leakage from the anus. This will recover after a few weeks.

For fissures that don't heal with creams or Bot Tox injection, surgery may be required. This takes the form of a small cut made into the lowest part of the anal sphincter muscle. This is known as a sphincterotomy and is carried out under general anaesthetic usually as a day case. This is a very effective procedure but occasionally this operation can result in some loss of control and leakage.
