What are the Types of Fistula?
The Types of Fistula are as follows:
Gastrointestinal fistula: These Types of Fistula have abnormal openings in the stomach and intestines that cause the contents to leak out into the body. These Types of fistulas are the results of surgery or from inflammatory bowel disease such as Crohn's disease or ulcerative colitis. Sometimes they may not have symptoms, but symptoms that could be present may include leakage from the contents of the intestine through the openings of the skin. .
Anal fistula: - An anal fistula is the result of an inflammatory tract between the anal canal and the skin. They begin in the anal crypts, which can become infected with abscess formation. If the abscess opens or ruptures, then it becomes a fistula. Symptoms may include itching, discharge or watery pus, rectal pain or an irritation of the skin around the anus.
Urinary fistula: - A urinary fistula is a Type of Fistula that has an abnormal opening in the urinary tract organs or an abnormal connection between the organs. There may be an opening in the bladder or problems with the colon. They might be caused from injuries during a surgery or trauma. Most often they are results of surgery of the bladder or pelvis. Symptoms may include leakage from the vagina, vulva irritation or many urinary tract infections
Arteriovenous fistula: - Individuals can be born with an arteriovenous fistula, but that is uncommon. Instead of blood flowing from the arteries into the capillaries and then to the veins, the blood flows from the artery directly into the vein without going into the capillaries at all. This Type of Fistula can occur if a person is stabbed with a knife or has been shot. It can develop quickly, or take some time. Symptoms may include a mass that can be felt, and the area may be swollen and warm to the touch.
Perilymph fistula: - This Type of Fistula happens when there is an abnormal connection in the air-filled middle ear and the fluid-filled inner ear. There may be an opening between those two areas where there could be complications in parts of the ear, such as the membranes called the round window and the oval window. Or there could be complications in the bone part of the ear which is called the otic capsule. Some of the symptoms of a perilymph fistula may include dizziness, hearing loss, sensitivity to pressure and sensitivity to loud noises.
