Association of Age at Duodenal Atresia Repair With Outcomes: A Pediatric NSQIP Analysis
JOURNAL OF PEDIATRIC SURGERY(2024)
Abstract
Purpose: Neonates with duodenal atresia (DA) are often born prematurely and undergo repair soon after birth, while others are delayed to allow for growth until closer to term corrected gestational age (cGA). Premature infants have been demonstrated to experience worse outcomes, but it is unclear whether delaying surgery mitigates the increased morbidity. This study evaluates the association of timing of DA repair with postoperative morbidity. Methods: We retrospectively evaluated neonates undergoing DA repair from the National Surgical Quality Improvement Program-Pediatric database (2015-2020). A multivariable regression analyzed factors associated with composite morbidity, including cGA and age in days of life (DOL) at surgery. A propensity score matched analysis was completed in premature neonates born at <= 35 weeks gestation to compare outcomes at similar birth gestational ages (bGA) and birth weight who underwent early (<7 DOL) versus delayed (>= 7 DOL) repair. Results: 809 neonates were included with a median bGA of 36 weeks (IQR 34-38), birth weight of 2.46 kg (IQR 1.96-2.95), and DOL at surgery of 2 (IQR 1-5). Infants born <= 35 weeks represented 35.23% of the cohort. On multivariable analysis, increasing cGA at surgery was associated with decreased morbidity (OR: 0.91, CI [0.84, 0.99]), and increasing DOL at surgery was associated with increased morbidity (OR: 1.02, CI [1.00, 1.04]). On propensity score matched analysis, delayed repairs were associated with increased postoperative ventilation (6 days vs. 2 days, p < 0.05); however, there were no differences in composite or surgical morbidity between early and delayed repairs. Conclusions: Morbidity after DA repair in neonates <= 35 weeks cGA is primarily driven by non-surgical causes, but delaying surgery does not appear to mitigate the risks associated with prematurity. It seems reasonable to consider repair in neonates around 33-34 weeks gestation without prohibitive risk factors. Optimal timing of DA repair requires a delicate balance between these factors. Level of Evidence: Level III. Type of Study: Retrospective Cohort Study.
