RESUMO
INTRODUCTION: Necrotizing enterocolitis (NEC) is a significant cause of morbidity and mortality among extremely premature infants. Approximately 50% of cases progress to surgery, frequently resulting in resection of necrotic bowel and ostomy creation. Premature neonates are at risk for bronchopulmonary dysplasia and feeding failure; surgery in these patients is higher risk. We evaluated the incidence of gastrostomy tube (GT) placement after ostomy reversal in surgical NEC to define a subset of patients who would benefit from concurrent ostomy reversal and GT placement. METHODS: A single-center retrospective study of infants with surgical NEC requiring ostomy creation between 2007 and 2021 was performed. RESULTS: Eighty patients met inclusion criteria. A GT was placed in 45/80 (56.3%), of which 3/45 (6.7%) were placed before, 20/45 (44.4%) concurrently with, and 22/45 (48.9%) after ostomy reversal. Between those who did and did not require GT placement, there were no significant differences in gestational age (27 versus 27 wk, P = 0.94) or birth weight (830 g versus 1055 g, P = 0.36). Hospital length of stay was longer in the GT group (128.2 versus 70.9 d, P < 0.0001). Time from ostomy reversal to hospital discharge was shorter when performed concurrently with GT (56 versus 77 d, P = 0.02). There were no differences in short-term or long-term GT related complications based on timing of GT placement. CONCLUSIONS: GT placement occurred in approximately 50% of patients with surgical NEC and GT may be accomplished safely at the time of ostomy reversal thus reducing the need for an additional procedure.

BACKGROUND: Micrognathia can be diagnosed in utero with ultrasound by measuring the jaw index and/or inferior facial angle, though it can be challenging due to fetal positioning. The jaw index can be measured with magnetic resonance imaging (MRI) using the masseter muscle, but indistinct margins can lead to inaccuracy; the easily visualized posterior teeth buds may be a better landmark. OBJECTIVE: We aimed to evaluate inter-reader variability, agreement with ultrasound, and association with postnatal outcomes using MRI to measure the inferior facial angle, jaw index by masseter muscle, and jaw index by posterior teeth buds. MATERIALS AND METHODS: A single-institution retrospective review was performed of singleton pregnancies with prenatally diagnosed micrognathia by ultrasound or MRI from September 2013-June 2022. Ultrasound measurements were obtained by a maternal-fetal medicine specialist and MRI measurements by two radiologists to evaluate inter-reader variability. Intraclass correlation coefficients (ICC) and Bland-Altman analysis were used to assess agreement between imaging methods and logistic regressions and ROC curves to assess associations with postnatal outcomes. RESULTS: Forty-three fetuses (median gestational age 26 weeks (IQR 22-31); 47% male (20/43)) were included. Ultrasound measurements could not be obtained for jaw index in 15/43 (35%) fetuses and inferior facial angle in 11/43 (26%); MRI measurements were obtained by at least one reader in all cases. Jaw index by teeth buds demonstrated lowest inter-reader variability (ICC = 0.82, P < 0.001) and highest agreement with ultrasound (bias -0.23, 95% CI -2.8-2.2). All MRI measurements, but not ultrasound, predicted need for mandibular distraction (inferior facial angle P = 0.02, jaw index by masseter muscle P = 0.04, jaw index by teeth buds P = 0.01). CONCLUSION: Fetal MRI measurements, particularly jaw index measured by posterior teeth buds, demonstrate low inter-reader variability and high agreement with ultrasound, and may predict need for mandibular distraction postnatally.
RESUMO
INTRODUCTION: Fetal growth restriction (FGR) is associated with impaired angiogenesis and chronic inflammation. MicroRNAs (miRs) are short noncoding RNAs that regulate gene expression at the post-transcriptional level by targeting messenger RNA (mRNA) for degradation or by suppressing translation. We hypothesize that dysregulation of miR-15b, an antiangiogenic miR, and miR-146a, an anti-inflammatory miR, are associated with the FGR's pathogenesis. METHODS: Pregnant mice were provided ad libitum access to food between E1 and E8. From E9-E18, dams received either a 50% caloric restricted diet (FGR) or continued ad libitum access (controls). Placentas were harvested at E18.5 and total RNA was extracted. Gene expression levels of miRs and mRNAs were compared between FGR and control placentas. RESULTS: Placentas affected by FGR demonstrated increased expression of miR-15b. Vascular endothelial growth factor alpha, which is downregulated in response to increased levels of miR-15b, was suppressed. The anti-inflammatory miR, miR-146a, was downregulated, resulting in upregulation of proinflammatory (IL-6, IL-8, and NFkB1) and oxidative stress (HIF-1α, SOD2, and Nox2) mediators. CONCLUSIONS: Aberrant angiogenesis and chronic inflammation seen in FGR appear to be associated with dysregulated miR-15b and miR-146a gene expression, respectively. This observation suggests these miRs play a post-transcriptional regulatory role in FGR, providing an insight into possible therapeutic targets.
RESUMO
INTRODUCTION: Children may require durable central venous catheters (CVCs) for various reasons. CVC-related integrity complications are common and can often be repaired at the bedside to increase lifetime. Variability in repair techniques can lead to complications, including the need for repeat repair and Central Line Associated Blood Stream Infection (CLABSI). METHODS: The impact of an educational curriculum to standardize tunneled CVC repairs for trainees on a pediatric surgery service was studied, focusing on comfort level with tunneled CVC repair and to determine the impact on complication rates. Rotating trainees studied a dedicated audiovisual educational curriculum comprised of a video, educational slides, and a practical component from November 2020 through January 2022. Experience and comfort level with tunneled CVC repairs were assessed before and after the rotation. CVCs repaired during the duration of the study were evaluated and compared to the period prior. RESULTS: Forty-nine individuals completed the pre- and post-training survey. Respondents (34.7%, n = 17) most commonly reported one year of surgical experience, and (79.6%, n = 39) had never observed or assisted in a repair previously. Following training, respondents felt more comfortable with all aspects of the CVC repair process (p < 0.001). There were no statistically significant differences in re-repair rates or CLABSI rates following the implementation of the curriculum. CONCLUSIONS: Tunneled CVC procedural repair variability can be standardized with a dedicated educational curriculum for rotating trainees, which improves knowledge and comfort with such procedures.

PURPOSE: Congenital heart disease (CHD) is a risk factor for the development of pneumatosis intestinalis (PI). Patients with single ventricle physiology (SVP) may be at higher risk of developing PI secondary to variations in systemic blood flow which affect bowel perfusion when compared to patients with biventricular physiology (BVP). We hypothesized that patients with SVP would have increased risk of recurrent PI. METHODS: A retrospective review was done from 10/2014 through 05/2020 with patients that met the following criteria: CHD, radiographic evidence of PI, and less than 1 year of age. Groups were divided based on ventricular physiology. Primary outcome was radiographic recurrence of PI and secondary outcomes were average antibiotic duration, NPO duration, median length of stay, need for GI operation, and death from PI. RESULTS: A total of 51 patients were included, 34 with SVP and 17 with BVP. 26.47% of SVP had recurrence of PI whereas no BVP experienced a recurrence of PI. There was no significant difference in any of the secondary outcomes. CONCLUSION: Our data suggest that patients with SVP are more likely to have recurrence of radiographic PI. We may need to consider patients with SVP that get PI as their own separate group.

BACKGROUND: Despite advancements in medical therapy for ulcerative colitis (UC), a significant proportion of children progress to colectomy with ileal pouch-anal anastomosis (IPAA). Procedural related complications between two- and three-stage operations in children have not been well described. METHODS: We performed a retrospective review of patients who underwent a colectomy for UC or inflammatory bowel disease unclassified between 2008 and 2018. RESULTS: Forty-nine children underwent an IPAA at the time of colectomy (two stage) or during a subsequent operation (three stage). Preoperative hemoglobin and albumin concentrations were lower among those undergoing three-stage procedures. The rate of early complications (≤30 days) was similar between the two groups (p = 0.46); however, late complications (>30 days) were more commonly associated with three-stage procedures (p = 0.03). Time with a stoma was 3.2 months longer among those who underwent a three-stage procedure. While three-stage procedures were more often performed during the first half of the study period (2008-2012), two-stage procedures became more common during the second half (2013-2018). During this transition to favor two-stage procedures, complication rates did not significantly change. CONCLUSION: Although three-stage procedures were thought to be associated with fewer complications, we found comparable complication rates as we transition to two-stage procedures.

BACKGROUND: Right congenital diaphragmatic hernia (CDH) occurs less frequently than left CDH. Therefore, prognostic indicators for right CDH are not as well studied as for left CDH. METHODS: A retrospective review from a single, tertiary referral center (from 1994 until July 2013) of patients with unilateral right CDH was conducted. Prenatal characteristics were evaluated and correlated with survival to discharge and need for extracorporeal membranous oxygen (ECMO). RESULTS: In total, 34 patients were identified. There were 12 postnatal deaths and 2 fetal demises (6%), representing an overall mortality of 41%. Six patients required ECMO. Nine patients underwent fetal intervention and were analyzed separately. For patients not undergoing fetal intervention, the survival rate was 52% and a higher mean (±SD) lung-to-head ratio (LHR) was associated with survival (1.1 ± 0.4 vs. 0.8 ± 0.2, p = 0.03). There were no deaths or need for ECMO in any patient with an LHR ≥1.0. Of the 9 patients who underwent fetal intervention, survival was 78% and only 1 patient required ECMO. Fetal intervention was primarily tracheal occlusion (n = 8). CONCLUSIONS: An LHR <1.0 is associated with worse survival for right CDH and may also reflect the need for ECMO.

Although in utero hematopoietic cell transplantation is a promising strategy to treat congenital hematopoietic disorders, levels of engraftment have not been therapeutic for diseases in which donor cells have no survival advantage. We used an antibody against the murine c-Kit receptor (ACK2) to deplete fetal host hematopoietic stem cells (HSCs) and increase space within the hematopoietic niche for donor cell engraftment. Fetal mice were injected with ACK2 on embryonic days 13.5 to 14.5 and surviving pups were transplanted with congenic hematopoietic cells on day of life 1. Low-dose ACK2 treatment effectively depleted HSCs within the bone marrow with minimal toxicity and the antibody was cleared from the serum before the neonatal transplantation. Chimerism levels were significantly higher in treated pups than in controls; both myeloid and lymphoid cell chimerism increased because of higher engraftment of HSCs in the bone marrow. To test the strategy of repeated HSC depletion and transplantation, some mice were treated with ACK2 postnatally, but the increase in engraftment was lower than that seen with prenatal treatment. We demonstrate a successful fetal conditioning strategy associated with minimal toxicity. Such strategies could be used to achieve clinically relevant levels of engraftment to treat congenital stem cell disorders.

INTRODUCTION: Amniotic band syndrome (ABS) is uncommon. We review our single-institutional experience to define its natural history and outcomes. MATERIALS AND METHODS: We conducted a retrospective analysis from a single, tertiary referral center of patients evaluated for and confirmed to have ABS from 1997 to 2012. RESULTS: Twenty-eight patients had confirmed ABS. The mean ± SD maternal age was 27.9 ± 5.9 years, and the mean gestational age at diagnosis was 20.7 ± 3.8 months. Oligohydramnios was reported in 4 patients. Eleven patients had membrane disruption, of whom 4 had undergone a prior percutaneous intervention. Extremities were the most common site affected (n = 20), followed by the umbilical cord (n = 7), abdomen (n = 5), limb-body wall complex (n = 5), head (n = 1), and chest (n = 1). Nine patients were felt to be candidates for fetal intervention; 5 underwent fetoscopic amniotic band lysis with 4 survivors. Overall survival, excluding 3 terminations, was 74%. There were 5 fetal demises and one neonatal death. Cord involvement was higher in nonsurvivors (67%) compared to survivors (19%, p = 0.05). DISCUSSION: ABS most commonly involves the extremities. Membrane disruption is not always present. Fetoscopic lysis is appropriate for select patients, and special consideration should be given for cord involvement, which is associated with a worse outcome.

PURPOSE OF REVIEW: Maternal-fetal cellular trafficking (MFCT) is the bidirectional passage of cells between mother and fetus during pregnancy. This results in the presence of fetal cells in the maternal circulation, known as fetal microchimerism, and maternal cells in the fetal circulation, known as maternal microchimerism. The biologic role of this transplacental cellular trafficking during pregnancy is not known, although it has been implicated in development of the fetal immune system, tolerance mechanisms during pregnancy, tissue repair in autoimmune disease and cancer, and immune surveillance. RECENT FINDINGS: Clinical utility of MFCT has been identified in prenatal testing for aneuploidies and prediction of pregnancy complications. Additionally, this transplacental passage of cells has been implicated in the delicate balance between immunologic priming and tolerance, which can influence the occurrence of autoimmune disease and transplantation outcomes. Ongoing studies are evaluating the utility of microchimerism in predicting the risk of graft rejection in transplantation. SUMMARY: In this review, we will discuss the clinical implications of MFCT in pregnancy, fetal surgery, autoimmune disease, transplantation, and cancer.

BACKGROUND: Open fetal resection for large lung lesions has virtually been replaced by maternal steroid administration. Despite this paradigm shift, little is known about the effects steroids have on lung lesion growth in utero. METHODS: A 10-year retrospective review of all prenatally diagnosed lung lesions cared for at our fetal care center was performed. We evaluated the effects of prenatal steroids on congenital pulmonary airway malformation (CPAM)-volume-ratio (CVR), distinguishing change in CVR among CPAMs, bronchopulmonary sequestrations (BPS), and bronchial atresias. We also correlated fetal ultrasound and MRI findings with pathology to determine the accuracy of prenatal diagnosis. RESULTS: We evaluated 199 fetuses with a prenatal lung lesion. Fifty-four (27 %) were treated with prenatal steroids with a subsequent 21 % mean reduction in the CVR (2.1 ± 1.4 to 1.1 ± 0.4, p = 0.003). Fetuses with hydrops and mediastinal shift who were treated with steroids rarely had resolution of these radiographic findings. Postnatal pathology was available for 91/199 patients (45.7 %). The most common diagnosis was CPAM (42/91, 46 %), followed by BPS (30/91, 33 %), and bronchial atresia (14/91, 15 %). Fetuses who received steroids and had pathology consistent with CPAM were more likely to have a reduction in their CVR (p = 0.02). Fetal ultrasound correctly diagnosed the type of lung lesion in 75 % of cases and fetal MRI in 81 % of cases. CONCLUSIONS: Prenatally diagnosed CPAMs are more likely to respond to maternal steroids than BPS or bronchial atresias. Knowing the diagnosis in utero could aid to steward steroid usage, however, fetal imagining modalities are not perfect in distinguishing subtype. LEVEL OF EVIDENCE: III.
RESUMO
Fetal growth restriction (FGR) is associated with aberrant placentation and accounts for a significant proportion of perinatal deaths. microRNAs have been shown to be dysregulated in FGR. The purpose of this study was to determine microRNA-regulated molecular pathways altered using a caloric restricted mouse model of FGR. Pregnant mice were subjected to a 50% caloric restricted diet beginning at E9. At E18.5, RNA sequencing of placental tissue was performed to identify differences in gene expression between caloric restricted and control placentas. Significant differences in gene expression between caloric restricted and control placentas were observed in 228 of the 1546 (14.7%) microRNAs. Functional analysis of microRNA-mRNA interactions demonstrated enrichment of several biological pathways with oxidative stress, apoptosis, and autophagy pathways upregulated and angiogenesis and signal transduction pathways downregulated. Ingenuity pathway analysis also suggested that ID1 signaling, a pathway integral for trophoblast differentiation, is also dysregulated in caloric restricted placentas. Thus, a maternal caloric restriction mouse model of FGR results in aberrant microRNA-regulated molecular pathways associated with angiogenesis, oxidative stress, signal transduction, apoptosis, and cell differentiation. As several of these pathways are dysregulated in human FGR, our findings suggest that this model may provide an excellent means to study placental microRNA derangements seen in FGR.

INTRODUCTION: Prosthetic patches (patch) and muscle flaps (flap) are techniques used for repair of congenital diaphragmatic hernia (CDH) with a large defect unamenable to primary closure. We hypothesized that the flap technique for CDH repair while on extra-corporeal membrane oxygenation (on-ECMO) would have decreased bleeding complications compared to patch due to the hemostatic advantage of native tissue. METHODS: A single-center retrospective comparative study of patients who underwent on-ECMO CDH repair between 2008 and 2022 was performed. RESULTS: Fifty-two patients met inclusion criteria: 18 patch (34.6%) and 34 flap (65.4%). There was no difference in CDH severity between groups. On univariate analysis, reoperation for surgical bleeding was lower following flap repair compared to patch (23.5% vs 55.6%, respectively; p = 0.045), 48-h postoperative blood product transfusion was lower after flap repair (132 mL/kg vs 273.5 mL/kg patch; p = 0.006), and two-year survival was increased in the flap repair group compared to patch (53.1% vs 17.7%, respectively; p = 0.036). On multivariate analysis adjusting for CDH side, day on ECMO repaired, and day of life CDH repaired, flap repair was significantly associated with lower five-day postoperative packed red blood cell transfusion amount, improved survival to hospital discharge, and improved two-year survival. CONCLUSIONS: Our experience suggests that the muscle flap technique for on-ECMO CDH repair is associated with reduced bleeding complications compared to prosthetic patch repair, which may in part be responsible for the improved survival seen in the flap repair group. These results support the flap repair technique as a favored method for on-ECMO CDH repair. LEVEL OF EVIDENCE: Level III.

OBJECTIVE: Treatment of neonates with anorectal malformations (ARMs) can be challenging due to variability in anatomic definitions, multiple approaches to surgical management, and heterogeneity of reported outcomes. The purpose of this systematic review is to summarize existing evidence, identify treatment controversies, and provide guidelines for perioperative care. METHODS: The American Pediatric Surgical Association Outcomes and Evidence Based Practice Committee (OEBP) drafted five consensus-based questions regarding management of children with ARMs. These questions were related to categorization of ARMs and optimal methods and timing of surgical management. A comprehensive search strategy was performed, and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were used to perform the systematic review to attempt to answer five questions related to surgical care of ARM. RESULTS: A total of 10,843 publications were reviewed, of which 90 were included in final recommendations, and some publications addressed more than one question (question: 1 n = 6, 2 n = 63, n = 15, 4 n = 44). Studies contained largely heterogenous groups of ARMs, making direct comparison for each subtype challenging and therefore, no specific recommendation for optimal surgical approach based on outcomes can be made. Both loop and divided colostomy may be acceptable methods of fecal diversion for patients with a diagnosis of anorectal malformation, however, loop colostomies have higher rates of prolapse in the literature reviewed. In terms of timing of repair, there did not appear to be significant differences in outcomes between early and late repair groups. Clear and uniform definitions are needed in order to ensure similar populations of patients are compared moving forward. Recommendations are provided based primarily on A-D levels of evidence. CONCLUSIONS: Evidence-based best practices for ARMs are lacking for many aspects of care. Multi-institutional registries have made progress to address some of these gaps. Further prospective and comparative studies are needed to improve care and provide consensus guidelines for this complex patient population.
RESUMO
PURPOSE: Fetal repair of myelomeningocele (MMC) and myeloschisis leads to improved neurologic outcomes compared to postnatal repair, but the effects of modifications in closure techniques have not been extensively studied. Previous work has suggested that a watertight repair is requisite for improvement in hindbrain herniation (HBH) and to decrease postnatal hydrocephalus (HCP). Our institution adopted the myofascial closure technique for open fetal MMC repair in July 2019, which we hypothesized would result in decreased need for patch closure, improved HBH, and decreased rate of surgically-treated HCP. METHODS: A single-center retrospective study of patients who underwent fetal MMC or myeloschisis repair between March 2013 and February 2022 was performed. Outcomes were evaluated (n = 70 prior to July 2019, n = 34 after July 2019). Statistical significance was determined by Fisher's exact and Chi square tests (p < 0.05 significant). RESULTS: Patients who underwent myofascial closure were less likely to require a patch for skin closure (14.7% vs 58.6%, p < 0.0001). Myofascial closure was also associated with an increased rate of HBH improvement on two-week postoperative fetal MRI (93.9% vs 65.7%, p = 0.002). Surgically-treated HCP at one year was lower in the myofascial closure group (n = 21), however this did not reach statistical significance (23.8% vs 41.9%, p = 0.19). CONCLUSIONS: We conclude that the myofascial closure technique for repair of fetal MMC and myeloschisis is associated with significantly decreased need for patch closure and improvement in hindbrain herniation compared to our previous skin closure technique. These results support a surgical approach that employs a multilayer watertight closure.

INTRODUCTION: Controversy exists in the optimal management of adolescent and young adult primary spontaneous pneumothorax. The American Pediatric Surgical Association (APSA) Outcomes and Evidence-Based Practice Committee performed a systematic review of the literature to develop evidence-based recommendations. METHODS: Ovid MEDLINE, Elsevier Embase, EBSCOhost CINAHL, Elsevier Scopus, and Wiley Cochrane Central Register of Controlled Trials databases were queried for literature related to spontaneous pneumothorax between January 1, 1990, and December 31, 2020, addressing (1) initial management, (2) advanced imaging, (3) timing of surgery, (4) operative technique, (5) management of contralateral side, and (6) management of recurrence. The Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) guidelines were followed. RESULTS: Seventy-nine manuscripts were included. Initial management of adolescent and young adult primary spontaneous pneumothorax should be guided by symptoms and can include observation, aspiration, or tube thoracostomy. There is no evidence of benefit for cross-sectional imaging. Patients with ongoing air leak may benefit from early operative intervention within 24-48 h. A video-assisted thoracoscopic surgery (VATS) approach with stapled blebectomy and pleural procedure should be considered. There is no evidence to support prophylactic management of the contralateral side. Recurrence after VATS can be treated with repeat VATS with intensification of pleural treatment. CONCLUSIONS: The management of adolescent and young adult primary spontaneous pneumothorax is varied. Best practices exist to optimize some aspects of care. Further prospective studies are needed to better determine optimal timing of operative intervention, the most effective operation, and management of recurrence after observation, tube thoracostomy, or operative intervention. LEVEL OF EVIDENCE: Level 4. TYPE OF STUDY: Systematic Review of Level 1-4 studies.

Extrahepatic liver (EL) rests are rare, with a reported annual incidence of 0.24-0.47. While reports often note EL incidentally found on pathologic specimens of aberrant tissue, there has been a case report of hepatocellular carcinoma arising from one of these rests, highlighting the importance of surgical resection. EL has been reported to cause symptoms such as abdominal pain, intraperitoneal bleeding and compression of adjacent organs. Most commonly, it has been identified in the gallbladder, likely due to proximity of the gallbladder to the native liver. The paucity of diagnostic tests makes the preoperative diagnosis challenging. We present a case of a 12-year-old female presenting with severe epigastric pain secondary to incapsulated EL tissue attached to the stomach via a narrow stalk. By describing this case, we hope to improve the diagnosis and management of abdominal masses with unclear etiology.
RESUMO
BACKGROUND: Adolescents with blunt solid organ injuries (BSOI) are cared for at both pediatric trauma centers (PTC) and adult trauma centers (ATC). Over the past decade, treatment strategies have shifted towards non-operative management with reported favorable outcomes. The aim of this study was to compare management strategies and outcomes between PTC and ATC. METHODS: We queried the 2016-2018 Trauma Quality Improvement Program (TQIP) datasets to identify adolescents between the ages of 16 and 19 with BSOI. Characteristics were stratified by center type (pediatric or adult) for comparative analyses. Separate logistic regressions were used to assess the association of hospital type, location of injury, age, gender, weight, Glascow Coma Score (GCS), Injury Severity Score (ISS), and intensive care unit (ICU) admissions for outcomes of interest. RESULTS: Among the 3,011,310 patients enrolled in the 2016-2018 TQIP datasets, 106,892 (3.5%) had a BSOI ICD9/10 code. Of those, 9,193 (8.6%) were between 16 and 19 years of age and included in this analysis. Within this cohort, 6,073 (66.1%) were managed at an ATC and 3,120 (33.9%) were managed at a PTC. While statistically different, there were no clinically relevant differences for age, weight, and sex between groups. A significantly higher ISS and lower GCS score were observed among those admitted to ATC compared to PTC. ICU admissions were more frequent at ATC. Number of blood transfusions by 4 h after presentation were also higher among those admitted to an ATC. Despite a lower ISS and higher GCS at presentation, mortality was higher among those treated at a PTC with an odds ratio (95% confidence interval) of 2.42 (1.31-4.53). After excluding adolescents with a traumatic brain injury, a common cause of mortality among adolescent trauma patients, these differences in outcomes persisted. CONCLUSIONS: Our data suggest that adolescents with BSOI managed at a PTC are less likely to receive blood transfusions by 4 h of admission or be admitted to the ICU than those managed at an ATC. However, this more conservative approach may come at the expense of higher overall mortality. Further work is needed to understand these differences and determine if PTC need to be more aggressive in managing BSOI.

BACKGROUND: Previous studies have examined characteristics critical to make a successful applicant in the pediatric surgery match. No previous study has focused on what applicants consider important as they interview pediatric surgery training programs. STUDY DESIGN: Successfully matched applicants to our training program from 2018 to 2020 were identified and a 49-question survey sent electronically. In addition to a descriptive analysis of responses, comparisons between those who matched into one of their top three programs and those who matched outside of their top three programs were made. A Likert scale was used and data are reported as mean (95% confidence intervals). RESULTS: One hundred and thirty individuals were surveyed. Sixty-three (48%) responded. The most important characteristics identified were total index case volume 1.94 (1.87, 2.00), interactions with faculty on the interview day 1.84 (1.74, 1.94), neonatal case volume 1.75 (1.61, 1.88) and degree of autonomy 1.63 (1.50, 1.77). Respondents also placed a high importance on the in-person interview experience 1.63 (1.49, 1.77).
