PURPOSE: The purpose of the study was to review a 10-year experience of operative procedures for rectovestibular fistula with normal anus (RVFNA) at one institution. MATERIALS AND METHODS: From January 1999 to December 2008, 182 female patients of RVFNA were treated surgically in the Department of Surgery, Beijing Children's Hospital, Capital Medical University, China. The patients' age ranged from 4 months to 15 years, with a mean age of 3.4 years. Fourteen children had a failed previous operation in other institutions. One hundred fifty-six patients (85.71%) had a definite history of vulvar inflammation within 3 months after birth and fecal leakage thereafter. In 61 of the 156 patients, a perineal abscess appeared after an episode of diarrhea. Four cases (2.20%) had associated anomalies of the VACTERL type. One hundred seventy-three patients (95.05%) had 1 external opening, whereas 9 others (4.95%) had 2 external openings separated by a skin bridge. In all cases, the internal orifice opened above the dentate line. The fistula in 135 cases (74.18%) presented as an opening with a small diameter (<5 mm). In our series, vestibular-rectal pull-through procedure was performed in 98 cases, transanal procedure in 69 cases, and anterior perineal anorectoplasty in 15 cases. None had a diverting colostomy. RESULTS: Recurrence of fistula occurred in 5 to 10 days after operation in 21 cases (11.54%). Eight of them healed spontaneously after daily sitz bath with 3% boric acid, whereas other 13 patients (7.14%) required reoperation. Follow-up was obtained by telephone or by personal visit in the outpatient department, from 3 months to 10 years (median, 5.7 years). All the patients were continent and had regular bowel movement. CONCLUSIONS: Most RVFNA was acquired after infection. Procedure requiring extensive perineal dissection and diverting colostomy are unnecessary in most RVFNA cases. We performed simple resection in most patients with satisfactory results. In the cases with a large external opening and abnormal perineal appearance, a more extensive perineal dissection might be necessary.
