Trans-fistula Anorectoplasty (TFARP) in the Management of Anorectal Malformation (ARM) with Recto Vestibular Fistula (RVF) in Females: A Retrospective Study

Abstract

Aim: To determine the outcome of trans-fistula anorectoplasty (TFARP) in female children having anorectal malformation with recto-vestibular fistula. Study Design: A retrospective study. Place and Duration: Department of pediatric surgery during the period of February 2018 to February 2020. Methodology: A total of 87 female children who have imperforate anus with recto-vestibular fistula from the age of 3 months to 6 years were included in this study. Initially, we have started this technique with the covering sigmoid colostomy, then TFARP after 12 weeks interval & once new anus healed and hegar dilatation achieved then sigmoid colostomy closed after 24 weeks of the first procedure. When we were experienced then we start TFARP as a single-stage procedure. Post-operative data regarding early complications of local wound infections, prolapse of the rectal mucosa, and late complications for anal stenosis, rectal prolapse, and scarring in the perineal body were collected up to 2-3 months respectively. Results: A total of 87 patients were included in this study. The average operative time was 40 minutes. The total days of hospital stay were 3 to 5 days. Regarding early complications, skin excoriation was present in 21 (24%) followed by vaginal tear in 17 (19%) cases. Mucosal prolapse was a late complication observed in 17 (20%) cases. Continence was good (Score 0) in 33 (38%) cases, while it was fair (score 1) in 36 (41%) cases. Conclusion: Primary repair of recto-vestibular fistula by Trans-fistula anorectoplasty in children is a feasible procedure that has a good cosmetic appearance and anal continence. Single-stage reconstruction is possible in children with satisfactory results. It produces less morbidity and is a more efficient procedure.
