Perianal Fistulas and Chrons Disease

Many people who suffer from chrons, then often go on to get fistulas of some sort, including Perianal fistulas. So what exactly is a Fistula?

The medical definition is that a fistula is an abnormal tunnel that connect two body cavities like the rectum to the vagina or it can connect a body cavity to the skin, so the rectum to the skin.Ok, so we now know what a fistula is, so then what is a Perianal Fistula? Quite simply a Perianal fistula is a fistula that connects the perianal skin with the anus or the rectum.

How are fistulas formed?
When a abscess in your body does not heal, this the eventually breaks through the skin or into another body cavity as described before.

It has been found that fistulas are far more common in people with chrons disease than those with ulcerative colitis and it has been found that about a quarter of people with Crohn's disease go on to develop a fistula.Perianal fistulas with people who have chrons can cause scarring, faecal incontinence, and in about 10 to 18% of people even proctectomy (which is a surgical resection of the rectum. Also called rectectomy.)

The diagnostic and therapeutic options to those with perianal fistulas available were limited, but this has started to change recently over the last ten years or so and the options for the diagnosis and treatment of fistulizing Crohn's disease have changed allot and are still continuing to change and improve even though the exact way to treat them is still controversial.
