Transanal fistula repair for the treatment of rectovestibular fistula with normal anus in female children: a 5-year single-center experience.

Abstract

The purpose of this study was to review a 5-year operative experience of transanal fistula repair for the treatment of rectovestibular fistula with a normal anus in female children. In this study, we conducted a retrospective review of children diagnosed with rectovestibular fistula with normal anus who underwent transanal fistula repair in the department of General Surgery, Children's Hospital of Chongqing Medical University. Clinical data were retrospectively analyzed. A total of 56 female children were included in the study. The patients' ages ranged from 1year 10months to 15years 11months, with an average age of 5years 1month. These children had a clear history of gas or loose stool leakage through the vestibular area, with or without a history of vestibular infection. All patients had a normal anus and underwent transanal fistula repair. Follow-up was conducted through telephone or outpatient visits for a duration of 10months to 5years (average follow-up duration 19months). Three patients experienced minimal secretion from the external orifice of the vestibular fistula within two weeks after the operation, but were successfully treated with sitting bath therapy without any relapse. Another three cases had a recurrence of the fistula, and two of them underwent transanal fistula repair at our center again, resulting in a successful cure after reoperation. The remaining case has not yet undergone reoperation. In the long-term follow-up, all the children had satisfactory anal appearance, with no fecal incontinence, anorectal stenosis, or fistula infection. Transanal fistula repair is a simple, safe, and effective surgical method to treat female children with rectovestibular fistula with a normal anus.
