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., (Copyright © 2023 Elsevier Inc.

Purpose: Children undergoing splenectomy for hemolytic anemia often have cholelithiasis, which may or may not be symptomatic. It is unclear whether concurrent cholecystectomy increases length of stay or morbidity after splenectomy. The purpose of this study was to compare morbidity among children undergoing laparoscopic splenectomy alone versus splenectomy with concurrent cholecystectomy in patients with hemolytic anemia., Methods: We retrospectively evaluated children with hemolytic anemia undergoing non-traumatic laparoscopic splenectomy in the National Surgical Quality Improvement Program-Pediatric database (2012-2020). Outcomes were compared for patients undergoing splenectomy alone (n = 1010) versus splenectomy with cholecystectomy (n = 371). Pearson's Chi-square and Student's t-tests were utilized as appropriate. Propensity score-matching was completed, controlling for eight demographic and clinical variables., Results: 1381 patients were identified, 73.1% undergoing splenectomy alone and 26.9% splenectomy with cholecystectomy. Splenectomy with cholecystectomy patients were older (10.9 years vs. 8.4 years, p < 0.01), more likely to have hereditary spherocytosis (56.1% vs. 40.8%, p < 0.01), less likely to have sickle cell disease (12.1% vs. 33.5%, p < 0.01), more likely ASA class 1 or 2 (49.3% vs. 42.1%, p < 0.01), and had similar preoperative hematocrit levels (29.6 vs. 29.3, p = 0.33). The splenectomy with cholecystectomy group was less likely to receive preoperative blood transfusions (13.5% vs. 25.4%, p < 0.01). There were 360 pairs selected on propensity score-matching, and splenectomy with cholecystectomy was associated with increased operative time (182 min vs. 145 min, p < 0.01) and decreased occurrences of a postoperative transfusion (4.2% vs. 8.9%, p = 0.01). Length of stay after surgery (2.5 days vs. 2.3 days, p = 0.13), composite morbidity (3.9% vs. 3.4%, p = 0.69), and 30-day readmission rates (3.3% vs. 7.4%, p = 0.08) were all similar., Conclusions: Splenectomy with cholecystectomy is associated with similar postoperative morbidity, length of stay and readmission rates compared to splenectomy alone. These data support the safety of concurrent cholecystectomy with splenectomy for children with cholelithiasis in the setting of hemolytic anemia., Type of Study: Retrospective Cohort Study., Level of Evidence: Level III., (Copyright © 2023 Elsevier Inc.
