Management of rectovaginal fistulas depends on several factors: cause, size, number, and location of the fistulas and the surgeon's preference. Anal sphincter integrity and prior operations influence the choice of treatment. Regardless of the approach chosen, several principles require consideration before repair.
What is rectovaginal fistula?
rectovaginal fistula is a complication of dystocia, usually resulting from an oversized or malpresented fetus. In 10.64 (taken 5 days postpartum) the ventral anal mucosa is torn and there are extensive lacerations to the dorsal vaginal wall. The white material on the vaginal floor originates from intrauterine therapy.
What causes a fistula to form?
Colovaginal and rectovaginal fistulas are thought to be a relatively uncommon occurrence, but they can cause distressing symptoms depending on the severity, site, location, and etiology.136 The most common cause of colovaginal fistulas is diverticular disease. They also occur as a result of irradiation, pelvic surgery, malignancy, abdominal hysterectomy, abscess formation, perforation by a foreign body, inflammatory bowel disease, and trauma. Fistulas develop in 2% of patients with diverticulitis. Most patients have colovaginal fistulas secondary to diverticular disease, Crohn's disease, or pelvic surgery, parti-cularly hysterectomy.
How long to wait for rectovaginal fistula repair?
Antibiotic coverage and topical hormonal replacement help optimize the health of local tissues and decrease any associated infection and inflammation. The health of the surrounding tissues influences the waiting period before surgical repair. Any inflammation or infection should be resolved. Waiting 3 to 6 months in these cases allows resolution and increases the chance of successful repair. In patients with prior failed repair, a longer waiting period may be necessary. In patients with postirradiation rectovaginal fistulas, a much longer waiting period may be required. Patients with complex fistulas (e.g., large size, radiation induced, neoplasm induced, multiple failed repairs) may require a diverting colostomy before formal repair. After diversion, a waiting period of 2 to 3 months before vaginal repair allows local tissue healing. Complete bowel preparation is given before surgery.

Cases of rectovaginal fistula as a result of tuberculosis and lymphogranuloma venereum have also been reported.1

Why are fistulas considered complex?
Rectovaginal fistulas are considered complex if they are large (>2.5 cm), high, or caused by inflammatory bowel disease. Recurrent fistulas are also considered complex due to their association with tissue scarring and decreased blood supply. To provide the best chance of successful repair, healthy, well-vascularized tissue needs to be introduced after resection of diseased tissue. In all, complex fistulas require more complicated surgical procedures for repair.
What is the most common transanal procedure?
Advancement flaps are the most popular transanal procedure among colorectal surgeons. Many variations exist; however, the general principle remains the same—excision and closure of the rectal portion of the fistula and coverage with a vascularized mucosal flap on the high pressure side of the fistula. The tract is identified by palpation and probing. The fistula tract is débrided and excised. A flap is created that includes mucosa, submucosa, and muscle placed over reapproximated rectovaginal septum (Fig. 3).19The flap base should be at least 2 to 3 times the width of the apex to ensure adequate vascular supply. Flap mobilization should continue 4 to 5 cm cephalad to the fistula defect. These principles ensure a tensionless suture line. As described in Table Table11success rates vary from 29 to 100%.19This wide discrepancy may be explained by differences in technique as well as patient selection. Complications are rare and minor, including fever, urinary tract infection, and spinal headaches.

Rectovaginal fistulas may be caused by childbirth. Prolonged labor with necrosis of the rectovaginal septum or obstetric injury with a third- or fourth-degree perineal tear or episiotomy can lead to rectovaginal fistula. Inadequate repair, breakdown of the repair, or infection can all result in fistula development. Fortunately, rectovaginal fistula from childbirth is less common in developed countries.

How to treat perianal fistula?
Surgical treatment of perianal fistulas was previously the treatment of choice. However, medical management with immune-modulating drugs is now the preferred therapy. Improvement can often be seen quickly; however, it can take several months of treatment to get the disease under control. Medical management is divided into an induction phase and a maintenance phase using drugs such as tacrolimus (brand name Protopic®), a topical medication and cyclosporine (brand name Atopica®), an oral medication. Antimicrobials are also often prescribed to treat secondary bacterial infections. A hypoallergenic food trial may be recommended since many cases have been linked to an underlying allergy. Increasing ventilation of the perianal region by clipping the area, particularly in long-coated dogs, combined with careful systematic bathing and cleaning is a useful palliative measure.
