Abstract
BackgroundAnorectal malformations (ARMs) have a wide spectrum of presentation ranging from mild defects with perineal fistulas to more severe defects requiring complex management. A primary repair of ARMs with perineal or rectovestibular fistulas has been shown to have good outcomes. However, the timing of the reconstruction is still debated. The aim of this study is to investigate the safety of early versus delayed repair. MethodsThis study was performed using data from the National Surgical Quality Improvement Program-Pediatric (NSQIP-P) from 2012 to 2017. Patients who underwent repair of anorectal malformation with perineal or vestibular fistula were included in the study. Patients with associated diagnosis for Hirschsprung disease, cloaca, rectal prolapse or stenosis, bladder exstrophy, and tracheoesophageal fistula were excluded. 30-day postoperative outcomes included wound and nonwound complications, readmissions, and reoperations. Outcomes were compared by early (≤7 days of age) versus delayed repair (6 weeks to 8 months). ResultsA total of 291 patients were included, with 66 in the early and 231 in the delayed group. Patients in the early group were more likely to be male (68.2% vs 31.8%; p < 0.01) and have cardiac risk factors (71.2% vs 49.4%, p < 0.01). The mean operative time was significantly shorter in the early group (90.1 vs 129.6 min; p < 0.01). 30-day complications were not statistically significant between the two groups (p = 0.76). After multivariate analysis, timing of repair did not affect 30-day complications (p = 0.15). ConclusionOur study shows that early repair of low anorectal malformations with a perineal or vestibular fistula appears to be associated with no increase in risk of postoperative complications as compared to delayed repair. At present, the decision remains dependent on the surgeon's experience and judgment. Level of evidenceLevel III. Retrospective comparative study.
