Anal fistulas (breech fistulas) are classified into four types according to their relationship with the muscles controlling the breech.
Intersphincteric Fistulas
It passes between the inner muscle and the outer muscle that controls the breech and opens into the breech.
Transfincteric Fistulas
It passes through the outer muscle that controls the breech and opens into the breech.
Suprasphincteric Fistulas
It passes through all of the muscles controlling the breech and opens into the breech.
Extrasphincteric Fistulas
It opens directly into the rectum, the last part of the large intestine, with the skin around the anus.
Fistulas heal spontaneously very rarely, and can rarely cause cancer if it lasts too long.
The choice of treatment is very important in a patient with fistula. An inadequate treatment causes the fistula to recur after a while. Or, after an uncontrolled intervention, the patient can not hold his ablution. For this reason, it is extremely important to perform the first surgery correctly. Because as the number of surgeries increases, the chance of success decreases.

Breech Anatomy – Anal Canal Anatomy
It is necessary to know the anal canal anatomy to understand the causes, treatment and complications of anal fistula (breech fistula – perianal fistula) disease.
The anal canal forms the last part of the gastrointestinal tract (gastrointestinal tract) (breech). The anal canal surrounds two layers of muscle. The external anal sphincter out of these muscles is the striped muscle that operates under the control of the person. The individual can postpone his toilet using this muscle. The inner layer consists of internal anal sphincter, smooth muscle fibers and is not under the control of the person. Both muscle layers play an important role in controlling a person’s stool and holding it.
Breech Structure
There is a junction between the layer covering the inside of the intestine and the skin layer within 1-2 cm of the anal canal. The glands in the anal canal are opened to this junction. The glands in the anal canal are located between the two muscle layers surrounding the canal and open to the anal canal at this junction level. The main task of the glands is to ensure the slipperiness of the anal canal and to facilitate the defecation function.
