Causes of anal fistula
Anal abscess : -
Anal fistulas most commonly develop as a result of an anal abscess. An abscess is a collection of pus and infected fluid. An anal abscess normally develops after a small gland, just inside the anus, becomes infected with bacteria or foreign matter. Abscesses are usually treated with a course of antibiotics. In most cases, you will also need to have the infected fluid drained away from the abscess. ...

* irritable bowel syndrome (IBS)
* diverticulitis
* ulcerative colitis
* Crohn's disease..
Diagnosing anal fistula

* Fistula probe - a fine, narrow instrument which is specifically designed to be inserted though a fistula...
f your fistula is in a complicated or unusual position, your doctor may also have to carry out further tests, which may include:
* Diluted methylene blue dye - this dye is injected into the fistula and it helps to show your doctor the fistula's position and path. The dye very rarely causes any side effects.
* Fistulography - this involves having a special solution injected into your fistula. You will then have an x-ray, which shows the path of the solution as an x- ray image...
Treating anal fistula
The main aim of treatment for an anal fistula is to heal the fistula with as little effect on the anal sphincter muscles (the ring of muscles that open and close the anus) as possible. Damage to the sphincter muscles could cause incontinence problems in the future.
Very few anal fistulas are able to heal by themselves, so surgery is usually necessary. ...
Fistulotomy : -
The main surgical procedure used to treat a fistula is a fistulotomy. During this procedure, the surgeon will cut open the fistula, whilst you are under general anaesthetic, and then scrape and flush out its contents. The fistula is then laid open and flattened out. After 1-2 months, the fistula will heal into a flat scar...
Fibrin glue or collagen plug : -
Most cases of anal fistula will require surgery, However, in some cases you may be able to have the fistula sealed with a special type of glue made from protein. This means the fistula will not have to be cut open. The glue is injected through the opening of the fistula, and then stitched closed. A fistula can also be sealed using a small plug made of collagen and then stitched closed.....
