Rectovaginal Fistula

Rectovaginal fistulas are vexing problems, causing considerable distress to the patient and challenging the skill of the surgeon. They comprise approximately 5% of anal fistulas and most commonly are caused by fourth-degree perineal tears or postoperative infection associated with childbirth. Thorough evaluation of the etiology and characteristics of the fistula help to guide surgical decision making and optimize the outcome after surgery.
