Background
The present article details a new technique for the repair of rectovestibular fistula.
Materials and Methods
Twenty-five patients with rectovestibular fistula, between 13 days and 4 years of age underwent surgical correction by transfistula anorectoplasty (TFARP). The technique, described in detail, involves mobilization of the fistula and the rectum through the fistula and creation of a new anus in the anatomically normal site by preserving both the perineal skin bridge (skin between the neo-anus and the posterior fourchette) and the levator muscle.
Results
The mean operating time was 85 min, and the mean hospital stay was 5 days. Moderate anal stenosis developed in 1 patient and was treated successfully by anal dilatations using Hegar dilators. A diverting colostomy was not required in any patient, and none of the patients developed rectal prolapse. Eleven patients who are now 3 years of age or older have voluntary bowel movements with good fecal continence scores. The 14 neonates and infants, who are still too young to be evaluated for continence, have symmetric anal contraction to stimulation and strong squeeze on digital rectal examination. The average number of bowel movements per day was three to five, without the need for any laxative or enema.
Conclusions
Transfistula anorectoplasty is a simple surgical procedure that does not divide the levator muscle or the perineal body. Preservation of these structures contributes significantly toward improvement of the aesthetic appearance of the perineum and of fecal continence.
