Rectovaginal fistula and anal-vaginal fistula are two rare diseases but have a significant impact on the patient's quality of life. Therefore, when experiencing these two conditions, patients should choose appropriate treatment methods early.

A rectovaginal fistula is an abnormal connection between the lower part of the large intestine and the vagina. Gas and feces from the rectum can leak through the fistula into the vagina, causing a lot of inconvenience for the patient in daily life. Some rectovaginal fistulas can close on their own, but most require surgery.
