Most cases are related to chronic inflammatory diseases such as Crohn's disease and tuberculosis. Others may result from diverticulitis, tumors, or chronic trauma. A surgery or an injury can lead to the production of a fistula, too, as in the case of biliary or arteriovenous fistulas.  Recto-vaginal fistulas may be secondary to Crohn's disease, obstetric injuries due to birth, radiation therapy or cancer. Fistulas in children or infants are mostly congenital affecting boys more than girls. Any fistula generally comes accompanied by these symptoms:  Constant discharge (pus) Pain (related to infection) Bleeding Pain in the abdomen Diarrhea Loss of appetite Weight loss Nausea and vomiting A fistula, by definition, is a tube-like tunnel with 2 openings: 1 primary opening leading to another exterior opening called the secondary opening. Many types of fistulas are known, but 90% of all fistulas are anorectal fistulas. Physically, they can take on the following forms:   Blind Fistula: A link between two surfaces; one end is closed and the other is opened. This can turn into a complete fistula if untreated.  Incomplete Fistula: A link has only one external opening.  Complete Fistula: A link between an internal opening and external opening.  Horseshoe Fistula: A link in a U shape, between two external openings around the anus. Unfortunately, a fistula's symptoms isn't where the problem stops — it can also lead to its own complications. They are the following:  Secretions that produce inflammation around the anal area Tumors of the anal canal Radial fungus disease (very rare) Exposure to severe trauma Cracks around the anal area Infections of the digestive tract Because of this, it is highly advised that you clean the anus well after using the toilet, observe the rules of public safety and personal hygiene, and use wipes after using the toilet and throw away after each use.
