Recto-vestibular disruption defect resulted from the malpractice in the treatment of the acquired recto-vestibular fistula in infants.

AIM: To explore the pathogenesis of the rectovestibular disruption (RVD) defect and to recommend a successful repair, and prevention of it.

METHODS

Clinical records of 15 girls, age ranged from 3 to 15 (median, 7.5) years, with acquired rectovestibular fistula (RVF) mistreated before were retrospectively reviewed. All of them presented an abnormal appearance of perineum and were suffering from some degree of fecal incontinence, and those were graded III to IV by Li Zheng's Score. Repair of anal sphincters and reconstruction of perineum body and skin by anterior perineal rectoanoplasty were performed in all cases.

RESULTS

Operation in all cases was successful. The perineum looked practically normal and fecal continence score rose up to VI by Li Zheng's Score.

CONCLUSION

The conventional treatment for anal fistula, lay-open or string-treatment, should be considered as malpractice of RVF, and certainly leads to the RVD defect, and the anterior perineal rectoanoplasty could cure it satisfactorily.
