The rectum and vagina are separated by a thin layer of tissue. Diseases that affect the gastrointestinal tract in this area, may lead to erosion or perforation of the vagina. Trauma, surgical complications and labor may produce similar results. Often the injuries or trauma may be complicated by infections that lead to the development of these abnormal channels of communication.
Causes of Rectovaginal Fistula
Prolonged labor can lead to damage to rectovaginal damage. This can later break down forming a communication. Tears of the perineum, that area that separates the vagina from the rectum can occur during the course of delivery. Not only can this lead to a rectovaginal fistula, but it can also lead to damage of the rectal sphincter. Inflammatory disease of the intestine, such as Crohn's disease, can lead to the formation of a fistula between the rectum and vagina. Penetrating trauma and surgical complications can similarly produce this disorder.
Signs and Symptoms of Rectovaginal Fistula
Rectovaginal fistulas can cause immediate problems with the vagina and rectum, or may lead to dysfunction of these organs at some future date. Incontinence of stool may occur. Sexual intercourse may be difficult or painful. Repeated vaginal infections or urinary tract infections may occur secondary to stool contamination of the vagina and urethra. There may be gas passed through the vagina. Intermittent abnormal vaginal discharge may be present.
