Abstract
BACKGROUND: Rectovaginal fistulas (RVFs) are very rare malformations in females with anorectal malformations (ARMs). Here, we share the clinical features of RVF and report the long-term outcomes. METHODS: RVF patients were classified using a retrospective analysis of ARM patients who underwent operations at Seoul National University Hospital between January 1999 and May 2017. The Krickenbeck continence scoring system was used to evaluate bowel function 5 and 10 years after surgery. RESULTS: Of the total 460 ARM patients, 203 were female, 7 of whom were diagnosed with RVF. The median age and weight at the time of anorectoplasty were 292 days (range, 140-617) and 8.2 kg (range, 5.5-12), respectively. Six patients had associated anomalies and three patients underwent redo-anorectoplasty. Voluntary bowel movements were observed in 6 out of 7 patients at 5 and 10 years of age. Soiling was observed in all patients at the age of five years and in 6 out of 7 patients at the age of ten years. Constipation was observed in 6 out of 7 patients at both five and ten years of age. CONCLUSIONS: An RVF is a very rare malformation, accounting for 1.5% of total ARMs and 3.4% of ARMs in females. Long-term counseling, education, and guidance are needed for effective management of patients' bowel movements. TYPE OF STUDY: Prognosis study LEVEL OF EVIDENCE: Level IV.
