When do you repair an anorectal malformation?
Topic overview
NSQIP-P analysis of 291 patients demonstrates that early repair of low anorectal malformations with perineal or vestibular fistulas (≤7 days) shows no increased 30-day complication risk compared to delayed repair (6 weeks-8 months), despite higher cardiac comorbidities in the early group. Early repair was associated with shorter operative times and comparable safety outcomes.
Key takeaways
- Early repair (≤7 days) of low ARMs with perineal/vestibular fistulas shows no increased 30-day complication risk versus delayed repair (6wks-8mo).
- Early repair had shorter operative times (90 vs 130 min) despite patients having more cardiac risk factors.
- Timing decision for low ARM repair remains surgeon-dependent; both early and delayed approaches appear safe based on NSQIP-P data.
- Exclude complex cases (cloaca, Hirschsprung, bladder exstrophy) when considering primary early repair of anorectal malformations.
