PURPOSE: The aim of this study was as an introduction of a technical modification to the anterior perineal approach for the treatment of anorectal anomalies (AA) and analysis of its long-term results.
METHODS: Forty-three children with AA underwent a modified anterior perineal anorectoplasty (APA), which involved the following technical guidelines: construction of a rectoanal muscular conduit through the levator ani muscle and the external anal sphincter, which were sutured to each other; preservation of the rectal end of the fistula; and invagination of the perineal skin through the neoanus. Fecal continence was assessed on average 7 years postreconstruction by Kelly's score.
RESULTS: Of the 20 patients (19 boys) with high AA, results were good, fair and poor in, respectively, 50%, 30%, and 20% of them. Results were good and fair in, respectively, 79% and 21% of the 14 patients (all girls) with intermediate AA. All 9 patients (7 boys) with low AA had good results. The differences among groups were statistically significant (P = .016).
CONCLUSIONS: This modified APA allows for the surgeon to securely identify, preserve, and reconstruct all anatomic structures that are relevant for fecal continence. The long-term results of this initial series suggest that this modified APA is a valuable alternative for the treatment of AA.
