RESUMO
OBJECTIVE: To evaluate the impact of repeat extracorporeal life support (ECLS) on survival and in-hospital outcomes in the congenital diaphragmatic hernia (CDH) neonates. BACKGROUND: Despite the widespread use of ECLS, investigations on multiple ECLS courses for CDH neonates are limited. METHODS: This is a retrospective cohort study of all ECLS-eligible CDH neonates enrolled in the Congenital Diaphragmatic Hernia Study Group registry between 1995 and 2019. CDH infants with estimated gestational age at birth <32 weeks and a birth weight <1.8 kg and/or with major cardiac or chromosomal anomalies were excluded. The primary outcomes were survival and morbidities during the index hospitalization. RESULTS: Of 10,089 ECLS-eligible CDH infants, 3025 (30%) received 1 ECLS course, and 160 (1.6%) received multiple courses. The overall survival rate for patients who underwent no ECLS, 1 ECLS course, and multicourse ECLS were 86.9±0.8%, 53.8±1.8%, and 43.1±7.7%, respectively. Overall ECLS survival rate is increased by 5.1±4.6% ( P =0.03) for CDH neonates treated at centers that conduct repeat ECLS compared with those that do not offer repeat ECLS. This suggests that there would be an overall survival benefit from increased use of multiple ECLS courses. Infants who did not receive ECLS support had the lowest morbidity risk, while survivors of multicourse ECLS had the highest rates of morbidities during the index hospitalization. CONCLUSIONS: Although survival is lower for repeat ECLS, the use of multiple ECLS courses has the potential to increase overall survival for CDH neonates. Increased use of repeat ECLS might be associated with improved survival. The potential survival advantage of repeat ECLS must be balanced against the increased risk of morbidities during the index hospitalization.

BACKGROUND: Inhaled nitric oxide (iNO) is widely used for the management of infants with congenital diaphragmatic hernia (CDH); however, evidence of benefit is limited. METHODS: This is a multicenter cohort study using data from the Congenital Diaphragmatic Hernia Study Group between 2015 and 2020. The impact of early iNO use in the first 3 days of life prior to ECLS use on mortality or ECLS use was explored using multivariate logistic regression models and subgroup analyses. RESULTS: Of the 1777 infants, 863 (48.6%) infants received early iNO treatment. Infants receiving iNO had lower birth weight, larger defect size, more severe pulmonary hypertension, and abnormal ventricular size and function. After controlling for these factors, early iNO use was associated with increased mortality (aOR 2.06, 95% CI 1.05-4.03, P = 0.03) and increased ECLS use (aOR 3.44, 95% CI 2.11-5.60, P < 0.001). Subgroup analyses after stratification by echocardiographic characteristics and defect size revealed no subgroup with a reduction in mortality or ECLS use. CONCLUSIONS: Use of iNO in the first 3 days of life prior to ECLS was not associated with a reduction in mortality or ECLS use in either the regression models or the subgroup analyses. The widespread use of iNO in this vulnerable population requires reconsideration. IMPACT: Evidence to support widespread use of iNO for infants with congenital diaphragmatic hernia is limited. The use of iNO in the first 3 days of life was associated with significantly increased mortality and ECLS use. Stratification by echocardiographic characteristics and defect size did not reveal a subgroup that benefited from iNO. Even the subset of patients with R-to-L shunts at both ductal and atrial levels, a surrogate for elevated pulmonary arterial pressures in the absence of significantly decreased LV compliance, did not benefit from early iNO use. Early iNO therapy was of no benefit in the management of acute pulmonary hypertension in infants with congenital diaphragmatic hernia, supporting reconsideration of its use in this population.

BACKGROUND: The aim of this study was to describe the incidence of Congenital Diaphragmatic Hernia, CDH, associated with known or clinically suspected syndromes, and the postnatal outcomes from a large database for CDH. METHODS: Data from the multicenter, multinational database on infants with CDH (Congenital Diaphragmatic Hernia Study Group Registry) born from 1996 to 2020 were analyzed. Patients with known or suspected syndromes were grouped and outcome data were analyzed and compared to those without syndromic features. RESULTS: A total of 12,553 patients were entered in the registry during the study period, and 421 had reported known syndromes, representing 3.4% of all CDH cases in the registry. A total of 50 different associated syndromes were reported. In addition to those with clinically suspected genetic conditions, a total rate of genetic syndromes with CDH was 8.2%. The overall survival to discharge for syndromic CDH was 34% and for non-syndromic CDH was 76.7%. The most common were syndromes Fryns syndrome (19.7% of all syndromes, 17% survival), trisomy 18 or Edward syndrome (17.5%, 9% survival), trisomy 21 or Down syndrome (9%, 47% survival), trisomy 13 or Patau syndrome (6.7%, 14% survival), Cornelia de Lange syndrome (6.4% of all syndromes, 22% survival) and Pallister-Killian syndrome (5.5% of all syndromes, 39.1% survival). In addition, 379 cases had reported chromosomal anomalies and 233 cases had clinically suspected syndromes, based on two more dysmorphic features or malformations in addition to CDH, but without molecular diagnosis. The syndromic CDH group had lower birth weight and gestational age at birth and increased incidence of bilateral CDH (2.9%) and rates of non-repair (53%). The length of hospital stay was longer, and larger number of patients needed O2 at 30 days. Extracorporeal life support was used only in 15% of the cases. Those who underwent surgical repair had survival to discharge rates of 73%. CONCLUSION: Syndromic CDH is rare and only 3.4% of the reported cases of CDH have a known syndrome or association, but, if including patients with two dysmorphic features malformations, in addition to CDH, altogether as many as 8.2% have a diagnosed or suspected genetic condition. These children have with lower survival rates. Given higher rates of non-repair and decreased extracorporeal life support use, along with a high early mortality, decision-making regarding goals of care clearly influences outcomes. Survival varies depending on the genetic cause. Early genetic diagnosis is important and may influence the decision-making.

OBJECTIVE: To determine in-hospital morbidities for neonates with right-sided congenital diaphragmatic hernia (R-CDH) compared with those with left-sided defects (L-CDH) and to examine the differential effect of laterality and defect size on morbidities. STUDY DESIGN: This retrospective, multicenter, cohort study from the international Congenital Diaphragmatic Hernia Study Group registry collected data from neonates with CDH surviving until hospital discharge from 90 neonatal intensive care units between January 1, 2007, and July 31, 2020. Major pulmonary, cardiac, neurologic, and gastrointestinal morbidities were compared between neonates with L-CDH and R-CDH, adjusted for prenatal and postnatal factors using logistic regression. RESULTS: Of 4123 survivors with CDH, those with R-CDH (n = 598 [15%]) compared with those with L-CDH (n = 3525 [85%]) had an increased odds of pulmonary (1.7; 95% CI, 1.4-2.2, P < .0001), cardiac (1.4; 95% CI, 1.1-1.8; P = .01), gastrointestinal (1.3; 95% CI, 1.1-1.6; P = .01), and multiple (1.6; 95% CI, 1.2-2.0; P < .001) in-hospital morbidities, with a greater likelihood of morbidity with increasing defect size. There was no difference in neurologic morbidities between the groups. CONCLUSIONS: Neonates with R-CDH and a larger defect size are at an increased risk for in-hospital morbidities. Counseling and clinical strategies should incorporate knowledge of these risks, and approach to neonatal R-CDH should be distinct from current practices targeted to L-CDH.

BACKGROUND: Congenital diaphragmatic hernia (CDH) is a morbid and potentially fatal condition that challenges providers. The aim of this study is to compare outcomes in neonates with prenatally diagnosed CDH that are inborn (delivered in the institution where definitive care for CDH is provided) versus outborn. METHODS: Prenatally diagnosed CDH cases were identified from the Congenital Diaphragmatic Hernia Study Group (CDHSG) database between 2007 and 2019. Using risk adjustment based on disease severity, we compared inborn versus outborn status using baseline risk and multivariable logistic regression models. The primary endpoint was mortality and the secondary endpoint was need for extracorporeal life support (ECLS). RESULTS: Of 4195 neonates with prenatally diagnosed CDH, 3087 (73.6%) were inborn and 1108 (26.4%) were outborn. There was no significant difference in birth weight, gestational age, or presence of additional congenital anomalies. There was no difference in mortality between inborn and outborn infants (32.6% versus 33.8%, P = 0.44) or ECLS requirement (30.9% versus 31.5%, P = 0.73). Among neonates requiring ECLS, outborn status was a risk factor for mortality (OR 1.51, 95% CI 1.13-2.01, P = 0.006). After adjusting for post-surgical defect size, which is not known prenatally, outborn status was no longer a risk factor for mortality for infants requiring ECLS. CONCLUSIONS: Risk of mortality and need for ECLS for inborn CDH patients is not different to outborn infants. Future studies should be directed to establishing whether highest risk infants are at risk for worse outcomes based on center of birth.

PURPOSE: Off-label use of prostacyclins to manage congenital diaphragmatic hernia-associated pulmonary hypertension (CDH-PHTN) has been described over recent years, but use is not standardized across institutions. This study aims to describe trends in use of these medications in the CDH Study Group (CDHSG) patients. METHODS: The CDHSG was queried for all patients born from 2007 to 2019. Records were reviewed to describe the number of patients receiving prostacyclins, the day of life on which the agent was started, start time relative to ECLS, the duration of medication use, and continuation of the medication at the time of discharge. Finally, trends in use by year of birth were evaluated to assess for changes in use over time. RESULTS: There were 6439 patients identified from the registry who were born during the study period. 4372 (68%) patients received medications to treat pulmonary hypertension. Of these, 604 (14%) received a prostacyclin at some point during their care. The median start time for prostacyclins was 7.5 days of life (mean 16.9 days, SD 32.5 days), and the median duration was 12.5 days (mean 25.1 days, SD 49.1 days). Among patients who received prostacyclins, 340 patients required ECLS during care, 53 (15.5%) of whom started the prostacyclin prior to ECLS, and 159 (46.8%) of whom started prostacyclin therapy during their ECLS run. Only a small cohort (26/604, 4.3%) required continuation of the prostacyclin at the time of discharge. The proportion of patients receiving a prostacyclin remained relatively stable over the study period. CONCLUSIONS: While the proportion of patients receiving a prostacyclin for management of CDH-PHTN has remained relatively stable over the last 13 years, there is significant variation in timing of initiation and duration of use especially in the pre-ECLS period that warrants further investigation to describe optimal use in these patients.

PURPOSE: Congenital diaphragmatic hernia (CDH) patients often have suspected isolated aortic arch anomalies (IAAA) on imaging. The purpose of this work was to describe the incidence and outcomes of CDH + IAAA patients. METHODS: Cardiovascular data were collected for infants from the CDH Study Group born between 2007 and 2019. IAAA were defined as coarctation of aorta, hypoplastic aortic arch, interrupted aortic arch, and aortic aneurysmal disease on early, postnatal echocardiography. Patients with major cardiac malformations and/or chromosomal abnormalities were excluded. Primary outcomes included the rate of aortic intervention, rates of extracorporeal life support (ECLS) utilization, and mortality. RESULTS: Of 6357 CDH infants, 432 (7%) were diagnosed with a thoracic aortic anomaly. Of these, 165 were diagnosed with IAAA, most commonly coarctation of the aorta (n = 106; 64%) or hypoplastic aortic arch (n = 58; 35%). CDH + IAAA patients had lower birthweights (3 kg vs. 2.9 kg) and Apgar scores (7 vs. 6) than patients without IAAA (both χ2 p < 0.001). CDH + IAAA were less likely to undergo diaphragm repair (72 vs. 87%, p < 0.001), and overall mortality was higher for CDH + IAAA infants (58 vs. 24%, p < 0.001). When controlling for defect size, birth weight, and Apgar, IAAA were significantly associated with mortality (OR 3.3, 95% CI 2.2-5.0; p < 0.01) but not associated with ECLS (OR 0.98, 95% CI 0.65-1.50; p = 0.90). Only 17% (n = 28) of CDH + IAAA patients underwent aortic intervention. CONCLUSIONS: IAAA in CDH are associated with increased mortality. This often simply reflects severity of the defect and thoracic anatomic derangement, as opposed to unique aortic pathology, given few CDH + IAAA patients undergo aortic intervention.

The Congenital Diaphragmatic Hernia Study Group (CDHSG) is an international consortium of medical centers actively collecting and voluntarily contributing data pertaining to live born congenital diaphragmatic hernia (CDH) patients born and/or managed at their institutions. These data are aggregated to construct a comprehensive registry that participating centers can access to address specific clinical inquiries and track patient outcomes. Since its establishment in 1995, 147 centers have taken part in this initiative, including 53 centers from 17 countries outside the United States, with 95 current active centers across the globe. The registry has amassed data on over 14,000 children, resulting in the creation of over 75 manuscripts based on registry data to date. International, multicenter consortia enable health care professionals managing uncommon, complex, and diverse diseases to formulate evidence-based hypotheses and draw meaningful and generalizable conclusions for clinical inquiries. This review will explore the formation and structure of the CDHSG and its registry, outlining their functions, center participation, and the evolution of data collection. Additionally, we will provide an overview of the evidence generated by the CDHSG, with a particular emphasis on contributions post-2014, and look ahead to the future directions the study group will take in addressing CDH.

BACKGROUND: Pulmonary hypertension (PHTN) causes significant morbidity and mortality in patients with congenital diaphragmatic hernia (CDH). Currently, there is no routinely obtained prenatal prognostic marker to reliably predict postnatal CDH-associated PHTN severity. METHODS: The CDH Study Group (CDHSG) registry was queried for infants born from 2015 to 2021 with a graded (1-4) PHTN diagnosis. Fetal observed-to-expected lung volume to head circumference ratio (o/e LHR), percent predicted lung volume (PPLV), and total lung volume (TLV) were classified by severity. RESULTS: Of 4056 patients, 1047 and 785 infants had prenatal ultrasound or magnetic resonance imaging, respectively. Both moderate and severe o/e LHR were associated with increased odds of postnatal development of moderate (OR 2.913) and severe PHTN (OR 4.924). CONCLUSIONS: In infants with CDH, prenatal predictor severity was associated with higher severity of PHTN and increased ECLS usage. Overall, patients with worse prenatal prognostic indicators were less likely to receive pulmonary vasodilator treatment.
RESUMO
OBJECTIVE: Congenital Diaphragmatic Hernia (CDH) associated with hydrops is rare. The aim of this study was to describe the incidence of this combination of anomalies and the postnatal outcomes from a large database for CDH. STUDY DESIGN: Data from the multicenter, multinational database on infants with prenatally diagnosed CDH (CDHSG Registry) born from 2015 to 2021 were analyzed. RESULTS: A total of 3985 patients were entered in the registry during the study period, 3156 were prenatally diagnosed and 88 were reported to have associated fluid in at least 1 compartment, representing 2.8% of all prenatally diagnosed CDH cases in the registry. The overall survival to discharge for CDH patients with hydrops was 43%. The hydropic CDH group had lower birth weight and gestational age at birth, and increased incidence of right-sided CDH (55%), and rate of non-repair (45%). However, the survival rate for hydropic infants with CDH undergoing surgical repair was 80%. Other associated anomalies were more common in hydropic CDH (50% vs 37%, p = 0.001). CONCLUSION: Hydropic CDH is rare, only 2.8% of all prenatally diagnosed cases, and more commonly occurring in right-sided CDH. Survival rates are low, with higher rates of non-repair. However, decision-making regarding goals of care and an aggressive surgical approach in selected cases may result in survival rates comparable to non-hydropic cases.
RESUMO
BACKGROUND: We aimed to investigate the clinical characteristics and outcomes of patients with isolated left-sided congenital diaphragmatic hernia (CDH) who developed preoperative pneumothorax and determine its risk factors. METHODS: We performed an international cohort study of patients with CDH enrolled in the Congenital Diaphragmatic Hernia Study Group registry between January 2015 and December 2020. The main outcomes assessed included survival to hospital discharge and preoperative pneumothorax development. The cumulative incidence of pneumothorax was estimated by the Gray test. The Fine and Gray competing risk regression model was used to identify the risk factors for pneumothorax. RESULTS: Data for 2858 neonates with isolated left-sided CDH were extracted; 224 (7.8%) developed preoperative pneumothorax. Among patients with a large diaphragmatic defect, those with pneumothorax had a significantly lower rate of survival to discharge than did those without. The competing risks model demonstrated that a patent ductus arteriosus with a right-to-left shunt flow after birth (hazard ratio [HR]: 1.78; 95% confidence interval [CI]: 1.21-2.63; p = 0.003) and large defects (HR: 1.65; 95% CI: 1.13-2.42; p = 0.01) were associated with an increased risk of preoperative pneumothorax. Significant differences were observed in the cumulative incidence of pneumothorax depending on defect size and shunt direction (p < 0.001). CONCLUSIONS: Pneumothorax is a significant preoperative complication associated with increased mortality in neonates with CDH, particularly in cases with large defects. Large diaphragmatic defects and persistent pulmonary hypertension were found to be risk factors for preoperative pneumothorax development. LEVEL OF EVIDENCE: LEVEL â ¢ Retrospective Comparative Study.

Importance: Prostacyclin (PGI2) is a therapeutic option to treat congenital diaphragmatic hernia (CDH)-associated pulmonary hypertension in neonates. Its use may decrease the need for extracorporeal life support (ECLS). Objective: To evaluate the association of early PGI2 therapy with ECLS use and outcomes among patients with CDH. Design, Setting, and Participants: This was a cohort study from the CDH Study Group (CDHSG) registry of patients born from January 2007 to December 2019. Patients were from 88 different tertiary pediatric referral centers worldwide that contributed data to the CDHSG. Patients were included in the study if they were admitted within the first week of life. Propensity score matching was performed using estimated gestational age, birth weight, transfer status, 1-minute and 5-minute Apgar scores, highest and lowest partial pressure of arterial carbon dioxide in the first 24 hours of life, and degree of pulmonary hypertension as covariates to generate a matched cohort of exposed and unexposed patients. Data were analyzed from January 2021 to December 2022. Exposures: Early PGI2 therapy was defined as initiation of PGI2 within the first week of life. Patients who received ECLS were included in the early PGI2 group if PGI2 was started prior to ECLS. Main Outcomes and Measures: The primary outcome of the study was the proportion of patients receiving ECLS in the exposed and unexposed groups. Results: Of 6227 patients who met inclusion criteria (mean [SD] gestational age, 37.4 [2.36] weeks; 2618 [42%] female), 206 (3.3%) received early PGI2 therapy. ECLS was used in 46 of 206 patients who received PGI2 (22.2%) and 1682 of 6021 who did not (27.9%). After propensity score matching, there were 147 patients in the treatment and control groups. Thirty-four patients who received PGI2 (23.3%) and 63 who did not (42.9%) received ECLS. Those who received PGI2 were less likely to receive ECLS (adjusted odds ratio, 0.39; 95% CI, 0.22-0.68) and had shorter mean (SD) duration of ECLS (8.6 [3.73] days vs 12.6 [6.61] days; P < .001), although there was no significant difference in in-hospital mortality. Conclusions and Relevance: In this study, there was decreased use of ECLS and decreased ECLS duration among patients with CDH who started PGI2 therapy during the first week of life. These results identify a potential advantage of early prostacyclin therapy in this population.

Background: Congenital diaphragmatic hernia (CDH) is associated with significant pulmonary morbidity. Previous investigation has shown that postnatal inpatient morbidity is linked to diaphragmatic defect size. The objective of this study was to evaluate long-term pulmonary outcomes by CDH study group defect size. Methods: A retrospective analysis was conducted for CDH patients (n=133) managed in a neonatal intensive care unit (NICU) at a single children's hospital within an adult hospital system and subsequently followed up at a comprehensive multidisciplinary CDH clinic (n=102) from January 2012 to April 2022. CDH patients were stratified according to Congenital Diaphragmatic Hernia Study Group (CDHSG) Stage, and then categorized as low-risk (LR), defect size A and B, or high-risk (HR), defect size C and D. Inpatient data, including the presence of pulmonary hypertension, extracorporeal life support (ECLS) utilization, and mechanical ventilation days, were collected. Post-discharge data including the prevalence of asthma, pulmonary hypertension, emergency department visits, the total number of hospitalizations, and average rehospitalization days were collected. Frequentist analysis was used. Results: The outcomes for 133 NICU patients were analyzed (HR: n=54, LR: n=79). During NICU stay, the prevalence of pulmonary hypertension [HR: 16/54 (30%) vs. LR: 9/79 (12%), P=0.009], ECLS utilization [HR: 19/54 (35%) vs. LR: 4/79 (5%), P<0.001], and the average number of mechanical ventilation days [HR: 17 days (IQR: 12-27) vs. LR: 5 days (IQR: 2-9), P<0.001] were significantly higher in the HR CDH group. Post NICU discharge, the prevalence of asthma [HR: 20/54 (37%), vs. LR: 17/79 (22%), P=0.050)] and the total days of rehospitalization [HR: 9 (IQR: 2-27) vs. LR: 4 (IQR: 1-8), P=0.035] were significantly higher in HR group. Of the patients seen in the comprehensive multidisciplinary CDH clinic, obstructive lung disease measured by impulse oscillometry was increased in the HR CDH population compared to the reference group [median R5Hz was 12.95 kPa/(L/s) in CDH vs. 9.8 kPa/(L/s) (P=0.010)]. Conclusions: HR CDHSG Stage is associated with worse inpatient and long-term pulmonary outcomes.
RESUMO
BACKGROUND: Emanuel Syndrome (ES), a rare chromosomal disorder caused by a supernumerary chromosome 22 derivative (der(22)t(11;22)), was identified in a fetus with congenital diaphragmatic hernia (CDH) at our fetal center. We aimed to identify a precedent for clinical care and patient outcomes to guide family decision-making. METHODS: This non-funded and non-registered study queried the entire CDH Registry (CDHR) including >10,000 patients since 1995 and conducted a systematic literature review for patients with concomitant ES and CDH. RESULTS: Literature review captured 12 citations and identified 9 patients with CDH+ES from over 400 known ES cases. Given the rarity of the disease and to reduce bias, there were no exclusion criteria aside from non-English language. Of these 9, two underwent surgical CDH repair with neither surviving. The CDHR identified 6 patients with ES, all reported after 2013 and prenatally diagnosed. Median estimated gestational age was 39 weeks (range 37-40) and median birth weight was 2.72 kg (range 2.4-3.4 kg). 3 patients died within the first few postnatal days; surgical repair was not offered due to "anomalies" and "pulmonary hypertension" in two and one family chose comfort measures. The other 3 patients underwent surgical repair, and 2 were supported with ECMO. Two patients survived to discharge, incurring surgical comorbidities associated with severe CDH including gastrostomy dependence, tracheostomy, and CDH recurrence. CONCLUSIONS: ES patients with CDH have potential to tolerate repair and survive to discharge, however with significant additional morbidity combined with severe challenges inherent to ES. This represents the largest series of patients with CDH and ES to date. LEVEL OF EVIDENCE: IV (Case series with no comparison group).

OBJECTIVE: To determine the association between prenatal ultrasound (US) and magnetic resonance imaging (MRI) characteristics in right congenital diaphragmatic hernia (RCDH) with postnatal outcome. STUDY DESIGN: CDH Study Group data were reviewed for all RCDH infants (n = 156) born between 2015 and 2019. Prenatal US and MRI lung size measurements were correlated with survival, extracorporeal life support (ECLS), and defect size. RESULT: Overall survival was 64.1%. ECLS was required in 40.4%. US and MRI-based prenatal assessment of pulmonary hypoplasia does not predict survival. Prenatal measurement of lung size using either US or MRI correlates with ECLS use. Only MRI-based measures of lung size are associated with defect size. CONCLUSION: Image-based prenatal predictors of survival, ECLS, and defect size are of limited value in RCDH. Extrapolation of prenatal survival and morbidity indicators from left to right-sided CDH is not appropriate. There is an urgent need to develop RCDH prenatal prediction models.

BACKGROUND: Bronchopulmonary sequestration (BPS) has long been identified in patients with congenital diaphragmatic hernia (CDH), however the reported incidence in the literature varies widely and is not based on large series. METHODS: Version 4 of the Congenital Diaphragmatic Hernia Study Group (CDHSG) included questions specifically identifying BPS-associated cases. The data were prospectively collected between 2015 and 2020. Clinical characteristics and outcomes for CDH+BPS patients were compared to patients without BPS using univariate and multiple regression analyses. RESULTS: Out of 2118 total patients, 72 had a pulmonary sequestration (3.4%). The amount of CDH+BPS with high-risk (CDHSG type C and D) defects was significantly greater than those without BPS (68.0% vs 49.3%, respectively; p = 0.001). The need for ECLS (35/72, 48.6%) and overall mortality (21/72, 29.2%) was significantly higher in CDH+BPS. When corrected for hernia size, cardiac and chromosomal anomalies, the need for ECLS (OR 2.2, p = 0.004) and mortality (OR 2.0, p = 0.015) was significantly greater in CDH+BPS. CONCLUSIONS: This is the largest series to look at the incidence of BPS in children with CDH. They are associated with larger defect sizes, a greater need for ECLS and higher mortality than those patients without BPS.

PURPOSE: There is a known association between Cornelia de Lange syndrome (CdLS) and congenital diaphragmatic hernia (CDH), with CDH being the cause of death in 5%-20% of CdLS cases. We aimed to identify and describe patients with CDLS and CDH. We hypothesized that CdLS would be associated with high-risk CDH and poor outcomes. METHODS: CDH Study Group patients from 1995 to 2019 were included. Those with CdLS were reviewed retrospectively. Rates of repair and outcomes were compared between patients with and without CdLS. RESULTS: We identified 9,251 CDH patients. Of those, 21 had confirmed CdLS. CdLS patients had a lower birth weight (2.2±0.57 kg) than non-CdLS patients (2.9±0.64 kg) (p<0.001). 5-min Apgar scores were lower in CdLS patients (6, 4-7) than non-CdLS patients (7, 5-8) (p=0.014). Only 33% of CdLS patients underwent diaphragmatic repair compared to 84.2% of non-CdLS patients (p<0.001). Mortality was 76% for CdLS patients compared with 29% for non-CdLS patients (p<0.001). Of the 7 CdLS patients who underwent repair, 5 survived to hospital discharge. CONCLUSIONS: Infants with CdLS and CDH have a poor prognosis. However, CdLS patients who undergo repair can survive to discharge; therefore, the concomitant diagnosis of CdLS and CDH is not necessarily a contraindication to repair. Early recognition of these anomalies can assist with counseling and prognostication. TYPE OF STUDY: Retrospective comparative study LEVEL OF EVIDENCE: III.

BACKGROUND/PURPOSE: The purpose of this study was to evaluate the characteristics of neonates with congenital diaphragmatic hernia (CDH) undergoing enteral access procedures (gastrostomy or jejunostomy) during their initial hospitalization, and establish a clinical scoring system based on these characteristics. METHODS: Data were obtained from the multicenter, multinational CDH Study Group database (CDHSG Registry) between 2007 and 2019. Patients were randomly partitioned into model-derivation and validation subsets. Weighted scores were assigned to risk factors based on their calculated ß-coefficients after logistic regression. RESULTS: Of 4537 total patients, 597 (13%) underwent gastrostomy or jejunostomy tube placement. In the derivation subset, factors independently associated with an increased risk for enteral access included oxygen requirement at 30-days, chromosomal abnormalities, gastroesophageal reflux, major cardiac anomalies, ECMO requirement, liver herniation, and increased defect size. Based on the devised scoring system, patients could be stratified into very low (0-4 points; <10% risk), low (5-6 points; 10-20% risk), intermediate (7-9 points; 30-60% risk), and high risk (≥10 points; 70% risk) groups for enteral access. CONCLUSION: This study identifies risk factors associated with enteral access procedures in neonates with congenital diaphragmatic hernia and establishes a novel scoring system that may be used to guide clinical decision making in those with poor oral feeding. TYPE OF STUDY: Prognosis study.
