Fistulas
In medicine, a fistula is an abnormal connection between two epithelialized (a covering) surfaces. Fistulae are usually caused by injury or surgery, but they can also result from an infection or inflammation. Fistulae are generally a disease condition, but they may be surgically created for therapeutic reasons. The secretions may be normal bodily secretions or may be pathological as in the case of fistula abscess. Evacuation can be performed within or without the body. The passageway of the fistula is necessary in order to successfully treat and foresee results and /or complications. Fistulae are most common in the anal area, digestive system or urinary system.
