What this trial studies

This ambispective multicenter cohort collects surgical and follow-up data on children with perineal or vestibular fistula repaired between 2020 and 2027, combining retrospective chart review with prospective annual visits. Functional outcomes including fecal continence (Krickenbeck score), postoperative complications (Clavien–Madadi classification), quality of life (HAQL), constipation and bowel management needs, and time to continence will be recorded. Patients enrolled after activation will be followed annually until continence is achieved or up to 6 years of age. Outcomes after PSARP (and variants), ASARP, and TAP will be compared to identify differences in mid- and long-term results.

Who should consider this trial

Good fit: Children under 18 with anorectal malformations presenting a perineal or vestibular fistula who underwent PSARP (or variants), ASARP, or TAP and whose parents or guardians provide consent are ideal candidates.

Not a fit: Patients with other types of anorectal malformations, those treated with different surgical techniques, or adults over 18 are unlikely to benefit from this comparison.

Why it matters

Potential benefit: If successful, this could help surgeons choose the best repair method to improve long-term fecal continence and quality of life for affected children.

How similar studies have performed: PSARP is established as the gold standard and some single-center comparisons exist, but there is limited multicenter long-term data directly comparing ASARP and TAP to PSARP, so this prospective multicenter approach adds needed evidence.
