diagnosis

1. Medical history: The woman or infant is born with congenital malformations of the rectum and anus; or the female patient has a history of birth trauma, or a history of abdominal or vaginal pelvic gynecological surgery or inflammatory bowel disease, or a history of vaginal medication or foreign objects, or a history of cancer erosion or radiotherapy, as well as a history of perineal penetration or closed injury, etc. 2. Clinical symptoms and signs: The patient has feces discharged from the vagina; the fistula can be seen under the exposure of the vaginal speculum, or the fistula can be touched by digital examination; or when the uterine probe is used to explore the vaginal fistula, the fingertip touches the probe head in the anus to confirm the diagnosis. If necessary, barium enema X-ray examination and methylene blue injection test can assist in the diagnosis.

Pathogenesis

Rectovaginal fistula can be classified according to its location, size and cause. 1. Classification by fistula location The anterior wall of the rectum in the distal 2/3 of the rectum is connected to the posterior wall of the vagina. Depending on its cause, rectovaginal fistula can occur in any part of the 9-cm recto-vaginal septum. Rectovaginal fistula is generally divided into 3 types.

(1) Low position: The fistula is located at the septum or above it, at the vaginal opening and at the frenulum of the labia. Some people have also suggested that the fistula is in the lower 1/3 of the rectum and the lower 1/2 of the vagina, which is easy to repair from the perineum.

(2) High position: Fistulas in the middle 1/3 of the rectum and the posterior fornix of the vagina near the cervix require transabdominal repair. The median is between the low and high positions. 2. Classification by fistula size: The size of the rectovaginal fistula is about 1 to 2 cm in diameter and can be divided into 3 types:

① Small: Fistula diameter <0.5cm;

②Intermediate type: 0.5～2cm; ③Large type: >2.5cm. The third-degree defect includes the entire posterior vaginal wall to the cervix.
