Abstract
Unexpected cardiac arrest in the perioperative period is a devastating complication. Owing to immaturity of organ systems, and presence of congenital malformations, morbidity and mortality are higher in neonates. There is abundant literature about early recognition and management of perioperative adverse events in children, but similar data and guidelines for surgical neonates is lacking. The current neonatal resuscitation guidelines cater to a newborn requiring resuscitation at the time of birth in the delivery room. The concerns in a newborn undergoing transition from intrauterine to extra uterine life is significantly different from a neonate undergoing surgery. This review highlights the causes and factors responsible for peri-arrest situations in neonates in the perioperative period, suggests preoperative surveillance for prevention of these conditions, and finally presents the resuscitation protocol of the surgical neonate. All these are comprehensively proposed as Neonatal Peri-operative Resuscitation (NePOR) protocol.

Being small for gestational age is not an independent risk factor for mortality in neonates with congenital diaphragmatic hernia: a multicenter study. J Perinatol 2022; 42:1183-1188. [PMID: 35449444 DOI: 10.1038/s41372-022-01326-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/30/2020] [Revised: 11/21/2021] [Accepted: 01/21/2022] [Indexed: 12/14/2022]
Abstract
BACKGROUND Congenital diaphragmatic hernia (CDH) accounts for 8% of all major congenital anomalies. Neonates who are small for gestational age (SGA) generally have a poorer prognosis. We sought to identify risk factors and variables associated with outcomes in neonates with CDH who are SGA in comparison to neonates who are appropriate for gestational age (AGA). METHODS We used the multicenter Diaphragmatic Hernia Research & Exploration Advancing Molecular Science (DHREAMS) study to include neonates enrolled from 2005 to 2019. Chi-squared or Fisher's exact tests were used to compare categorical variables and t tests or Wilcoxon rank sum for continuous variables. Cox model analyzed time to event outcomes and logistic regression analyzed binary outcomes. RESULTS 589 neonates were examined. Ninety were SGA (15.3%). SGA patients were more likely to be female (p = 0.003), have a left sided CDH (p = 0.05), have additional congenital anomalies and be diagnosed with a genetic syndrome (p < 0.001). On initial single-variable analysis, SGA correlated with higher frequency of death prior to discharge (p < 0.001) and supplemental oxygen requirement at 28 days (p = 0.005). Twice as many SGA patients died before repair (12.2% vs 6.4%, p = 0.04). Using unadjusted Cox model, the risk of death prior to discharge among SGA patients was 1.57 times the risk for AGA patients (p = 0.029). There was no correlation between SGA and need for ECMO, pulmonary hypertensive medication at discharge or oxygen at discharge. After adjusting for confounding variables, SGA no longer correlated with mortality prior to discharge or incidence of unrepaired defects but remained significant for oxygen requirement at 28 days (p = 0.03). CONCLUSION Infants with CDH who are SGA have worse survival and poorer lung function than AGA infants. However, the outcome of SGA neonates is impacted by other factors including gestational age, genetic syndromes, and particularly congenital anomalies that contribute heavily to their poorer prognosis.

Abstract
PURPOSE This study determined the prevalence, mortality, and time trends of children with congenital diaphragmatic hernia (CDH). METHODS Twenty-five hospital- and population-based surveillance programs in 19 International Clearinghouse for Birth Defects Surveillance and Research member countries provided birth defects mortality data between 1974 and 2015. CDH cases included live births, stillbirths, or elective termination of pregnancy for fetal anomalies. Prevalence, cumulative mortality rates, and 95% confidence intervals (CIs) were calculated using Poisson regression and a Kaplan-Meier product-limit method. Joinpoint regression analyses were conducted to assess time trends. RESULTS The prevalence of CDH was 2.6 per 10,000 total births (95% CI: 2.5-2.7), slightly increasing between 2001 and 2012 (average annual percent change = 0.5%; 95% CI:-0.6 to 1.6). The total percent mortality of CDH was 37.7%, with hospital-based registries having more deaths among live births than population-based registries (45.1% vs. 33.8%). Mortality rates decreased over time (average annual percent change = -2.4%; 95% CI: -3.8 to 1.1). Most deaths due to CDH occurred among 2- to 6-day-old infants for both registry types (36.3%, hospital-based; 12.1%, population-based). CONCLUSIONS The mortality of CDH has decreased over time. Mortality remains high during the first week and varied by registry type.

Abstract
PURPOSE To determine the global prevalence for congenital diaphragmatic hernia (CDH) and identify CDH-related risk factors. METHODS Using a defined strategy, a systematic review of the literature was conducted according to PRISMA guidelines, searching for population-based epidemiological studies to evaluate the prevalence of CDH globally and per country. Studies containing overlapping populations or timeframes were excluded. CDH-related risk factors were calculated by meta-analysis using RevMan5.3 and expressed as risk ratio and 95% confidence interval. RESULTS Prevalence: Of 8230 abstracts screened, 30 full-text articles published between 1980 and 2019 were included. The overall prevalence of CDH was 2.3 in 10,000 births (16,710 CDH babies in 73,663,758 livebirths). RISK FACTORS From 9 studies we found that male sex [RR 1.38 (1.05-1.80), p=0.02] and maternal age >35 years [RR 1.69 (1.26-2.25), p=0.0004] were associated with CDH. Conversely, maternal black ethnicity resulted as a protective factor [RR 0.82 (0.77-0.89, p<0.00001]. CONCLUSION This study reveals that there is a worldwide paucity of population-based studies, and those studies that report on prevalence and risk factors come from a small number of countries. The prevalence of CDH varies within and across geographical world regions. The main risk factors for CDH identified are male sex and older maternal age. More epidemiological studies, involving more world regions, are needed to identify possible strategies to help strengthen our understanding of the risk factors, provide clinicians with the tools necessary for prenatal and postnatal counseling, and inform policy makers on how to strategize CDH care in different parts of the world.

Abstract
PURPOSE The purpose of this study was to evaluate the impact of congenital heart disease (CHD) on infants with congenital diaphragmatic hernia (CDH). METHODS Using a defined search strategy (PubMed, Cochrane, Embase, Web of Science MeSH headings), we searched studies reporting the incidence, management, and outcome of CDH infants born with associated CHD. RESULTS Of 6410 abstracts, 117 met criteria. Overall, out of 28,974 babies with CDH, 4427 (15%) had CHD, of which 42% were critical. CDH repair was performed in a lower proportion of infants with CHD (72%) than in those without (85%; p < 0.0001). Compared to CDH babies without CHD, those born with a cardiac lesion were more likely to have a patch repair (45% vs. 30%; p < 0.01) and less likely to undergo minimally invasive surgery (5% vs. 17%; p < 0.0001). CDH babies with CHD had a lower survival rate than those without CHD (52 vs. 73%; p < 0.001). Survival was even lower (32%) in babies with critical CHD. CONCLUSION CHD has a strong impact on the management and outcome of infants with CDH. The combination of CDH and CHD results in lower survival than those without CHD or an isolated cardiac defect. Further studies are needed to address some specific aspects of the management of this fragile CDH cohort. TYPE OF STUDY Systematic review and meta-analysis. LEVEL OF EVIDENCE Level III.

Abstract
Purpose: The aim of this research is to study the predictors of neonatal surgical mortality (NSM)-defined as in-hospital death or death within 30 days of neonatal surgery. Materials and Methods: All neonates operated over the study period of 18 months were included to evaluate NSM. The evaluated preoperative and intraoperative variables were birth weight, gestation age, age at presentation, associated anomalies, site and duration of surgery, intraoperative blood loss, and temperature after surgery. Assessed postoperative variables included the need for vasopressors, postoperative ventilation, sepsis, reoperations, and time taken to achieve full enteral nutrition. Univariate and multivariate logistic regression was applied to find the predictors of mortality. Results: Based on patient's final outcome, patients were divided into two groups (Group 1-survival, n = 100 and Group 2-mortality, n = 50). Incidence of NSM in this series was 33.33%. Factors identified as predictors of NSM were duration of surgery >120 min (P = 0.007, odds ratio [OR]: 9.76), need for prolonged ventilation (P = 0.037, OR: 5.77), requirement of high dose of vasopressors (P = 0.003, OR: 25.65) and reoperations (P = 0.031, OR: 7.16 (1.20–42.81). Conclusion: NSM was largely dependent on intraoperative stress factors and postoperative care. Neonatal surgery has a negligible margin of error and warrants expertize to minimize the duration of surgery and complications requiring reoperations. Based on our observations, we suggest a risk stratification score for neonatal surgery.

Abstract
BACKGROUND Congenital diaphragmatic hernia (CDH) is a malformation of the diaphragm accounting for 8% of all major congenital anomalies. Although many clinical factors of survival in children with CDH have been established, limited research exists on the role of sociodemographic and other factors. We aimed to systematically identify and summarize all available international literature, published from January 2000 to July 2017, evaluating specific mortality factors for children with prenatally diagnosed, isolated, left-sided CDH. METHODS MEDLINE, PROSPERO, EMBASE, Scopus, The Cochrane Library databases, and the table of contents for the past 5 years for relevant journals were searched systematically. The risk factors of interest were as follows: birth weight, gestational age (GA) at diagnosis, GA at birth, infant sex, maternal age, ethnicity, socioeconomic status (SES), and plurality. The primary outcome measure was survival. Data were extracted on study design, study quality, participant data, and survival-related effect estimates. RESULTS Seven studies fulfilled the inclusion criteria. In total, 347 children were included in the review. Birth weight, GA at diagnosis, and GA at birth were evaluated in five studies each, infant sex in two, and maternal age in one. None of these factors were significantly associated with survival. No studies evaluated the influence of plurality, ethnicity or SES. CONCLUSION Although the factors of interest showed no significant association with survival, more evidence is required to confirm these findings. Understanding whether sociodemographic factors are associated with survival may help inform the development of public health interventions to improve survival rates for children with CDH.

ULTRASOUND IN OBSTETRICS & GYNECOLOGY : THE OFFICIAL JOURNAL OF THE INTERNATIONAL SOCIETY OF ULTRASOUND IN OBSTETRICS AND GYNECOLOGY 2018; 51:208-213. [PMID: 28295742 DOI: 10.1002/uog.17463] [Citation(s) in RCA: 29] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/15/2016] [Revised: 02/20/2017] [Accepted: 03/03/2017] [Indexed: 06/06/2023]
Abstract
OBJECTIVE Congenital diaphragmatic hernia (CDH) is a severe anomaly. The observed-to-expected lung-area-to-head-circumference ratio (o/e-LHR) has been shown to provide a useful prediction of subsequent survival of fetuses with CDH in referral centers with expertise and a large caseload. However, the accuracy of o/e-LHR measurements in general fetal medicine units with less expertise is not well known. The aim of this study was to evaluate the capacity of o/e-LHR to provide a useful prediction of mortality of fetuses with CDH when the measurement is performed in fetal medicine units with different levels of expertise. METHODS Between January 2008 and November 2013, 305 live births with expectantly managed left-sided isolated CDH were recorded in the database of the French National Center for Rare Diseases (31 centers) and followed up after birth. Centers were grouped into two categories according to their mean annual CDH caseload over the study period: large centers with an average of ≥ 14 cases and smaller centers with < 14 cases per year. The relationship between o/e-LHR and 28-day and 6-month mortality was modeled using fractional polynomials and the predictive value of o/e-LHR was quantified using the area under the receiver-operating characteristics curve. Comparisons between the two center categories were carried out. Analyses were adjusted for potential confounders such as thoracic herniation of the liver and gestational age at birth and at diagnosis. RESULTS During the study period, two large centers managed a total of 82 CDH cases and 29 smaller centers a total of 223 CDH cases. Overall, there was a significant inverse relationship between 28-day mortality rate and o/e-LHR, which decreased from 54% when o/e-LHR was 20% to 6% when o/e-LHR was 75% (P < 0.01). When the category of center was considered, adjusted associations between o/e-LHR and 28-day mortality were significantly different (P = 0.032) between large and smaller centers. The ability to predict survival at 28 days postpartum based on o/e-LHR was better in large centers; for a specificity of 0.30, the sensitivity was 0.71 in large centers and 0.55 in smaller ones. The results were similar for 6-month mortality. CONCLUSIONS Our results show that o/e-LHR measured on two-dimensional ultrasound is a good indicator of neonatal prognosis in cases of CDH that may be used even in fetal medicine centers with a small caseload. However, our results also suggest that LHR measurement may be difficult to perform correctly. Therefore, appropriate training should be offered to professionals. Copyright © 2017 ISUOG.

Abstract
OBJECTIVE The rate of congenital diaphragmatic hernia (CDH) varies, but most reports estimate the incidence to be less than three per 10,000 births. Our objective was to document the incidence of CDH in a geographically well-defined population using available resources for highly accurate incident case ascertainment. METHODS We ascertained CDH cases in Olmsted County, Minnesota, United States of America, from 1981 through 2014 using resources of the Rochester Epidemiology Project. Overall and sex-specific incidence rates were calculated, and hospital survival was assessed. RESULTS A total of 26 incident CDH cases were identified; the overall incidence of 3.6 (95% CI, 2.2-5.0) per 10,000 did not differ significantly over the 34-year study period (p = .28). The estimated incidence was 4.3 (95% CI, 2.2-6.5) for male infants and 2.9 (95% CI, 1.1-4.6) for female infants. The percentage of cases diagnosed prenatally was 33% from 1981 through 2000 and 50% from 2001 through 2014. The rate of survival to discharge in the two periods was 50% and 88%. CONCLUSION The incidence of CDH in Olmsted County exceeds the majority of published rates, which most likely can be attributed to our comprehensive case ascertainment.

Abstract
BACKGROUND Congenital diaphragmatic hernia (CDH) is a relatively frequent and severe malformation. Population-based data on clinical presentation and associated mortality are scarce. We examined a state-wide cohort of infants with a clinically validated diagnosis of CDH to assess their clinical profile, sociodemographic patterns, and infant mortality. METHODS We identified CDH cases from Utah's statewide population-based surveillance program among the cohort of all pregnancy outcomes (live births, stillbirths, and pregnancy terminations) delivered from 1999 to 2011. Clinical geneticists reviewed all cases and classified them based on etiology (known, unknown), and whether they were isolated, multiple (additional unrelated major malformations or unique minor malformation), or syndromic (genetic, chromosomal). RESULTS CDH occurred in 1 in 3156 births (227/718,990, or 3.17 per 10,000), with no time trend during the 13 years (p = 0.85). CDH was much more common in males (male to female ratio, 1.72:1; p < 0.01). Clinically, 64% of the cases were isolated, 23% were multiples, and 13% were syndromic. Most cases were live born (90%), with fewer stillbirths (7%) and pregnancy terminations (3%). Overall infant mortality was 32.5%, and varied considerably by underlying etiology (isolated 21%; multiple 44%; syndromic 82%). Prognosis was related to specific clinical findings within each etiologic group (e.g., prematurity, low Apgar score, and intrathoracic liver). CONCLUSION This information on specific clinical and etiologic factors associated with prognosis can help clinicians and parents in the complex discussions about care planning and management that often occur in a crisis situation, following the diagnosis of CDH, whether prior or after delivery.

Abstract
PURPOSE The aim was to review the respiratory failure causes and outcomes of infants with omphalocele or gastroschisis receiving ECMO and reported to the Extracorporeal Life Support Organization (ELSO). METHODS Gastroschisis and omphalocele infants supported with ECMO and reported to the ELSO Registry between 1992 and 2015 were retrospectively reviewed. Clinical variables, diagnosis of respiratory failure (pulmonary hypertension (PHN), congenital heart defects (CHD), congenital diaphragmatic hernia (CDH), and sepsis), and outcomes were recorded. Univariate analysis was performed using Student's t-test for continuous or Fisher's exact test for categorical variables. RESULTS Fifty-two infants with gastroschisis (41) (79%) or omphalocele (11) (21%) were identified. The survival to discharge rate of 51% for gastroschisis remained stable and was significantly higher (P=0.05). The overall mortality rate for omphalocele was 82%. Omphalocele had significantly more PHN (P<0.01), CDH (P<0.01), and multiple anomalies (P=0.04) had significantly more sepsis (P=0.02), and none had a CDH. CONCLUSION Infants with gastroschisis requiring ECMO support have significantly better survival than omphaloceles, and respiratory failure is significantly associated with sepsis. The majority of omphalocele infants die despite ECMO, and respiratory failure is associated PHN and CDH. The association of omphalocele, PHN, and CDH merits further investigation. STUDY TYPE AND EVIDENCE LEVEL Retrospective comparative study of Registry Database, Level 3.

Abstract
INTRODUCTION The pathogenesis of congenital diaphragmatic hernia (CDH) is not clear. Risk factors including environmental factors have been implicated in the pathogenesis of few congenital anomalies. We aimed to assess the effect of season on the incidence of CDH and mortality rate in the southwest of Iran. MATERIAL AND METHODS In this retrospective study, the records of 60 patients with CDH who were admitted at Neonatal Intensive Care Unit (NICU) of Imam Khomeini Hospital of Ahvaz, Iran were evaluated. RESULTS Assuming that all the neonates born with CDH in the region reach this hospital, overall CDH prevalence rate was 1.09 per 10 000 total births. Conceptions in spring and summer in this region had statistically significantly higher incidence of CDH. Survival rate in the series was 41.6%. CONCLUSION Seasonal variation has impact on the incidence of CDH. Mortality rate in neonates with CDH is still very high.

Abstract
Neonatal surgery is recognized as an independent discipline in general surgery, requiring the expertise of pediatric surgeons to optimize outcomes in infants with surgical conditions. Survival following neonatal surgery has improved dramatically in the past 60 years. Improvements in pediatric surgical outcomes are in part attributable to improved understanding of neonatal physiology, specialized pediatric anesthesia, neonatal critical care including sophisticated cardiopulmonary support, utilization of parenteral nutrition and adjustments in fluid management, refinement of surgical technique, and advances in surgical technology including minimally invasive options. Nevertheless, short and long-term complications following neonatal surgery continue to have profound and sometimes lasting effects on individual patients, families, and society.

Abstract
BACKGROUND Outcomes of neonates with congenital diaphragmatic hernia (CDH) are variable; reports are frequently limited to the experience of single tertiary care centres-a possible source of bias. Population-based studies decrease survivor bias and provide additional insight into this high-mortality condition. The objective of this study was to examine the incidence and outcomes of CDH in Croatia. METHODS All cases of CDH in Croatia from 2001 through 2013 were ascertained from public health records. Overall and sex- and region-specific incidence rates were calculated, and characteristics associated with 1-year survival were assessed. RESULTS We identified 145 cases of CDH during the study period, for an incidence of 2.67 per 10 000 total births. The incidence did not differ by calendar year (P = 0.38) or geographic region (P = 0.67). There was a slightly higher incidence among males (rate ratio, 1.37, 95% CI 0.99, 1.91). The 1-year survival rate was 33.1% for the entire cohort and 47.9% for liveborns who received any treatment at an intensive care unit. From multivariable analysis, survival was decreased in neonates with left CDH, liver up (odds ratio 0.1, 95% CI, 0.03, 0.4) and increased when treated in a centre with higher case volume (odds ratio 12.8, 95% CI, 2.2, 72.1). CONCLUSIONS The incidence of CDH in Croatia is within the range of previous reports. Survival was substantially higher in neonates treated in a centre with higher case volume, which suggests that centralisation of medical care for CDH may be warranted in Croatia.

Abstract
OBJECTIVE Our study had two objectives. First, we separately evaluated observed-to-expected MR fetal lung volume (FLV) of lungs ipsilateral and contralateral to a congenital diaphragmatic hernia (CDH). Second, we compared the prognostic value of observed-to-expected MR FLV of the ipsilateral and contralateral lungs with that of observed-to-expected MR FLV of both lungs with respect to survival, need for extracorporeal membrane oxygenation (ECMO), and development of chronic lung disease (CLD). MATERIALS AND METHODS We evaluated observed-to-expected MR FLV of the lung ipsilateral to the diaphragmatic defect as well as in the contralateral lung in 107 fetuses with isolated CDH. ROC analysis and logistic regression analysis were performed to assess the prognostic value of the observed-to-expected MR FLV for association with outcome. RESULTS In all fetuses with CDH, values in the ipsilateral (mean observed-to-expected MR FLV ± SD, 9.4% ± 9.6%) and the contralateral lung (mean observed-to-expected MR FLV, 48.9% ± 18.5%; p < 0.0001) were significantly lower than values measured in healthy fetuses. Observed-to-expected MR FLV of both lungs and of the contralateral and ipsilateral lung revealed significant differences regarding survival (p < 0.0001, p < 0.0001, and p = 0.0170, respectively), need for ECMO (p < 0.0001, p < 0.0001, and p = 0.0051, respectively), and development of CLD (p = 0.0004, p = 0.0002, and p = 0.0460, respectively). Compared with the observed-to-expected MR FLV of both lungs, the observed-to-expected MR FLV of the contralateral lung showed a slightly higher prognostic accuracy regarding survival (AUC = 0.859 vs 0.825) and development of CLD (AUC = 0.734 vs 0.732) and a similar prognostic accuracy regarding need for ECMO (AUC = 0.805 vs 0.826). Observed-to-expected MR FLV of the ipsilateral lung did not show good prognostic value regarding survival (AUC = 0.617), need for ECMO (AUC = 0.673), and development of CLD (AUC = 0.636). These AUCs were significantly smaller than the AUCs resulting from the observed-to-expected MR FLV of both lungs (each p < 0.05) and considerably smaller than the AUCs of the observed-to-expected MR FLV of the contralateral lung (each p < 0.10). CONCLUSION Patients with CDH showed a substantially lower observed-to-expected MR FLV of both lungs compared with healthy fetuses. The observed-to-expected MR FLV of both lungs as well as of the lung contralateral to the CDH were reliable prenatal predictors of survival, need for ECMO, and development of CLD.

Abstract
PURPOSE The purpose of this study was to evaluate the impact of various types of associated anomalies on CDH mortality and morbidity. METHODS All CDH patients at a tertiary care center from January 2004 to January 2014 were reviewed retrospectively. Isolated CDH was defined as CDH without any associated anomalies. Cardiac anomalies were stratified into minor and major based on the Risk Adjustment for Congenital Heart Surgery-1 (RACHS-1) scoring system. Other anatomic anomalies requiring intervention in the perinatal period were classified as major anomalies. The outcomes of interest were 6-month mortality as well as pulmonary and gastrointestinal morbidity. RESULTS Of 189 CDH patients, 93 (49%) had isolated CDH. Others had: cardiac anomalies alone (n=47, 25%), genetic anomalies (n=28, 15%), structural anomalies alone (n=18, 10%), and both cardiac and genetic anomalies (n=20, 11%). Fifty (26.5%) patients were dead before six months of age. Mortality rate at 6months was higher in patients with genetic and major cardiac anomalies. A major cardiac anomaly was independently associated with a 102-fold increased risk of mortality at 6months (95%CI: 3.1-3402). Pulmonary morbidity was increased in patients with genetic, major cardiac, and major structural anomalies, while gastrointestinal morbidity was higher in patients with major structural anomalies alone. CONCLUSION Major cardiac and genetic anomalies were associated with increased 6-month mortality in CDH patients. However, the association with minor cardiac anomalies and/or structural anomalies did not affect mortality and morbidity of CDH patients. The presence of minor anomalies should not adversely impact their perinatal management or consideration for in-utero therapy.

Congenital diaphragmatic hernia: does gestational age at diagnosis matter when evaluating morbidity and mortality? Am J Obstet Gynecol 2015; 213:535.e1-7. [PMID: 26070705 DOI: 10.1016/j.ajog.2015.06.012] [Citation(s) in RCA: 29] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/02/2015] [Revised: 04/12/2015] [Accepted: 06/01/2015] [Indexed: 11/22/2022]
Abstract
OBJECTIVE The objective of the investigation was to study the relationship between gestational age at diagnosis and mortality and morbidity in fetuses with an isolated congenital diaphragmatic hernia. STUDY DESIGN Between January 2008 and November 2013, 377 live births with isolated congenital diaphragmatic hernia diagnosed antenatally at a known gestational age were recorded in the database of the French National Center for Rare Diseases. The primary outcome studied was mortality estimated at 28 days and at 6 months. The secondary outcome was morbidity evaluated by pulmonary arterial hypertension at 48 hours, oxygen therapy dependence at 28 days, oral disorders, enteral feeding, and prosthetic patch repair. Analyses were adjusted for the main factors of congenital diaphragmatic hernia severity (side of the hernia, thoracic herniation of the liver, gestational age at birth, lung-to-head ratio, and prenatal treatment by tracheal occlusion. RESULTS Mortality rates at 28 days decreased significantly (P < .001) when gestational age at diagnosis increased: 61.1%, 39.2%, and 10.4% for a diagnosis in the first, second, and third trimester, respectively. Adjusted odds ratios were 3.12 [95% confidence interval, 1.86-5.25] and 0.35 [95% confidence interval, 0.18-0.66] for a diagnosis in the first and third trimesters, respectively, compared with a diagnosis in the second trimester. Similarly, morbidity decreased significantly when gestational age at diagnosis increased, and the trend remained significant after adjustment for the main factors of congenital diaphragmatic hernia severity (P < .001). CONCLUSION Gestational age at diagnosis is an independent predictor of postnatal prognosis for children presenting an isolated congenital diaphragmatic hernia and should be taken into account when estimating postnatal morbidity and mortality.

Abstract
OBJECTIVE We performed a retrospective cohort study in order to examine recent trends in use of post-partum treatments and in-hospital mortality for congenital diaphragmatic hernia (CDH). STUDY DESIGN Included were infants with CDH, born in 2003 to 2012 and hospitalized at ⩽7 days of age at one of 33 United States tertiary referral children's hospitals with extracorporeal membrane oxygenation (ECMO) programs. In-hospital mortality as well as use of ECMO, surfactant and a variety of vasodilators were examined for trends during the study period. RESULT Inclusion criteria were met by 3123 infants with CDH. Among 2423 term or near-term infants, odds of death decreased annually for those with isolated or complex CDH. For 700 premature or low-birth weight infants with CDH, in-hospital mortality did not change. Among treatments for CDH, increasing with time in the study cohort were use of milrinone and sildenafil individually, and use of multiple vasodilators during the hospitalization. CONCLUSION Survival improved in large subgroups of term or near-term infants with CDH in this 10-year multicenter cohort, temporally associated with increasing use of multiple vasodilators. Use of vasodilators for infants with CDH is increasing despite a lack of evidence supporting efficacy or safety. Prospective research is needed to clarify specific causal effects contributing to improving survival in these infants.

Abstract
BACKGROUND Within congenital diaphragmatic hernia (CDH) care, there have been attempts to identify clinical parameters associated with patient survival, including markers of postnatal pulmonary gas exchange. This study aimed to identify whether postnatal pulmonary gas exchange parameters correlated with CDH patient survival. METHODS A retrospective review was performed of isolated CDH neonates treated at a single institution from 1/2007 to 12/2013. Patient demographics, prenatal imaging, and postnatal clinical parameters, including arterial blood gas values within the first 24hours of life, were collected. RESULTS Seventy-four patients with isolated CDH were identified. Fifty-seven had fetal MRI. Overall, 30-day patient survival was 85%. Sixteen infants (22%) required ECMO within 24hours. Mean initial PaCO2 in nonsurvivors was higher, and infants who remained hypercarbic postresuscitation (72±19mmHg) had a worse prognosis than those who resuscitated to a normal PaCO2 (39±1.6mmHg) (p<0.001). Prenatal fetal lung volumes measured by MRI were not strongly correlated with PaCO2 levels. CONCLUSION CDH nonsurvivors are unable to maintain sufficient pulmonary gas exchange during the first 24hours of resuscitation. Furthermore, prenatal fetal lung volumes are weakly correlated with actual pulmonary gas exchange. These data may be useful for patient counseling during the resuscitative phase of CDH care.

Abstract
This study aimed to demonstrate that congenital diaphragmatic hernia (CDH) results in
vascular abnormalities that are directly associated with the severity of pulmonary
hypoplasia and hypertension. These events increase right ventricle (RV) afterload and
may adversely affect disease management and patient survival. Our objective was to
investigate cardiac function, specifically right ventricular changes, immediately
after birth and relate them to myocardial histological findings in a CDH model.
Pregnant New Zealand rabbits underwent the surgical procedure at 25 days of gestation
(n=14). CDH was created in one fetus per horn (n=16), and the other fetuses were used
as controls (n=20). At term (30 days), fetuses were removed, immediately dried and
weighed before undergoing four-parameter echocardiography. The lungs and the heart
were removed, weighed, and histologically analyzed. CDH animals had smaller total
lung weight (P<0.005), left lung weight (P<0.005), and lung-to-body ratio
(P<0.005). Echocardiography revealed a smaller left-to-right ventricle ratio
(LV/RV, P<0.005) and larger diastolic right ventricle size (DRVS, P<0.007).
Histologic analysis revealed a larger number of myocytes undergoing mitotic division
(186 vs 132, P<0.05) in CDH hearts. Immediate RV dilation of CDH
hearts is related to myocyte mitosis increase. This information may aid the design of
future strategies to address pulmonary hypertension in CDH.

Abstract
The aim of this study was to report the birth prevalence and short-term outcome of congenital diaphragmatic hernia (CDH) in a large geographically defined population, and to assess the feasibility of performing a randomised control trial (RCT) in this population. Data were collected on all cases of CDH reported to the East Midlands and South Yorkshire Congenital Anomalies Register between 1997 and 2005. A total of 194 cases of CDH were identified from 547,025 births; a birth prevalence of 3.5/10,000. Overall 1-year survival was 42%. In total, 69% of cases resulted in a live birth, of these 61% survived to 1 year; 73% were diagnosed antenatally and 22% postnatally, with 1-year survivals 30% and 71%, respectively. A total of 54% were isolated cases and 46% associated with another anomaly, with more live births (80% vs. 56%) and better 1-year survival (62% vs. 19%) with isolated CDH. Overall, only 83 babies were born alive with an isolated CDH: the only group suitable for inclusion in a RCT. In conclusion, given the small numbers of live isolated CDH cases it is impossible that any network alone would be able to perform a valid RCT of treatments, highlighting the need for collaborative international trials to address this complex condition.

Abstract
OBJECTIVE To review outcomes of patients with congenital diaphragmatic hernia (CDH) requiring extracorporeal membrane oxygenation (ECMO) at a level IIIC neonatal intensive care unit and to determine if pre-ECMO respiratory status can help predict mortality. STUDY DESIGN A single-center retrospective chart review was conducted on all infants with CDH treated with ECMO in the past 15 years. Demographic and clinical information, including pre-ECMO ventilatory and blood gas data, was collected. Differences between survivors and non-survivors were evaluated using independent samples t-/Mann-Whitney U-and Fisher's exact/chi (2)-tests for continuous and categorical data, respectively. Cox regression analysis was performed to evaluate predictors of survival while controlling for covariates. Significant predictors were further explored with receiver operating characteristic (ROC) curve and Kaplan-Meier survival analysis. RESULT Overall survival of the population of 62 patients treated with ECMO was 50%. Survivor and non-survivors were similar in birth weight, gestational age, gender, race and Apgar scores. Approximately 80% of patients in both groups had a left-sided defect. Less than half of patients were prenatally diagnosed in either group. Patients in the non-survivor group had associated anomalies (42 vs 23% for survivors) but this was not statistically significant (P=0.303). Non-survivors were more likely to be put on ECMO earlier, stay on ECMO longer and be operated upon later. On pre-ECMO blood gas analyses, survivors had higher pH and PaO(2), and lower oxygenation index and PaCO(2) compared with non-survivors. After controlling for covariates, a lower minimum PaCO(2) and side of defect were the only independent predictors of survival. ROC curve for minimum pre-ECMO PaCO(2) had a significant area under the curve (0.72, P=0.003). Survival was 27% in babies unable to achieve a pre-ECMO PaCO(2) <60 mm Hg whereas no patients survived if their lowest pre-ECMO PaCO(2) was >70 mm Hg. CONCLUSION Minimum achievable pre-ECMO PaCO(2) is an independent predictor of survival in patients with CDH requiring ECMO life support. These data provide useful prognostic information for counseling families and may facilitate direction of care in extreme cases where the degree of pulmonary hypoplasia may be incompatible with life.

Abstract
BACKGROUND Despite advances in therapeutic modalities, congenital diaphragmatic hernia (CDH) still accounts for significant neonatal mortality. This study aimed to describe the demographic features, clinical experiences of postnatal care, and differences between non-survivors and survivors with CDH. METHODS We retrospectively reviewed medical records of neonates with CDH admitted to Kaohsiung Chang Gung Memorial Hospital over a 21-year period. Neonates with diaphragmatic eventration and those transferred after surgery were excluded. RESULTS A total of 24 live-born neonates fulfilled the study criteria; 13 (54%) were boys and 11 (46%) were girls. Eight (33%) patients were prenatally diagnosed. The mean gestational age was 38.8 +/- 1.8 weeks (range, 35-41 weeks). Twenty-three (96%) had Bochdalek hernia [19 (83%) left-sided, 4 (17%) right-sided], and one (4%) had right-sided Morgagni hernia. Additional major congenital anomalies were identified in five patients (21%). The overall mortality was 21% (5/24); all deaths occurred before surgery. Statistically significant differences between survivors and non-survivors were found for right-sided CDH, low 1-minute and 5-minute Apgar scores, and low pH of the first arterial blood gas. Deaths were attributed to severe persistent pulmonary hypertension, unresponsiveness to aggressive resuscitation at birth, and major associated malformations. CONCLUSION Seventy-nine percent of our CDH patients survived to hospital discharge. Resuscitation by a skilled neonatology team to prevent low Apgar scores and low pH, careful evaluation of other anomalies, and overcoming pulmonary hypertension might improve the survival rate. Recognizing unfavorable factors in CDH may help clinicians manage the critical care of these babies.

Abstract
OBJECTIVE Congenital diaphragmatic hernia (CDH) has a poor prognosis, despite intensive management. The prognosis of CDH is correlated with hypoplastic lung, but it is difficult to measure the degree of hypoplasia. The aims of this study were, therefore, to examine the relationship between chest X-ray and prognosis, and to assess whether the radiographic findings were a good indicator of hypoplastic lungs in patients with CDH. STUDY DESIGN Fifty neonates with CDH were classified radiographically into apex and hilar types. To assess the differences in clinical course between these two groups, gestational age, birth weight, prenatal diagnosis, survival rate, requirement of extracorporeal membrane oxygenation (ECMO) therapy and lung area on X-rays were analyzed. RESULTS In all, 32 cases were of the apex type and 18 were hilar. The survival rate of the hilar group (33%) was significantly worse than that of the apex group (81%) (P<0.001). The hilar group required ECMO therapy more frequently than did the apex group. CONCLUSIONS The present results show a significant correlation between survival rate and the findings of chest X-rays in CDH. Radiographic findings are thus a good clinical indicator of the prognosis of CDH in neonates.

Abstract
PURPOSE Venoarterial extracorporeal membrane oxygenation (ECMO) (VA) is used more commonly in neonates with congenital diaphragmatic hernia (CDH) than venovenous ECMO (VV). We hypothesized that VV may result in comparable outcomes in infants with CDH requiring ECMO. METHODS We retrospectively analyzed the Extracorporeal Life Support Organization (ELSO) database (1991-2006). Multivariate logistic regression analyses were used to compare VV- and VA-associated mortality. RESULTS Four thousand one hundred fifteen neonates required ECMO, with an overall mortality rate of 49.6%. Venoarterial ECMO was used in 82% and VV in 18% of neonates. Pre-ECMO inotrope use and complications were equivalent between VA and VV. The mortality rate for VA and VV was 50% and 46%, respectively. After adjusting for birth weight, gestational age, prenatal diagnosis, ethnicity, Apgar scores, pH less than 7.20, Paco(2) greater than 50, requiring high-frequency ventilation, and year of ECMO, there was no difference in mortality between VV vs VA. Renal complications and on-ECMO inotrope use were more common with VV, whereas neurologic complications were more common with VA. The conversion rate from VV to VA was 18%; conversion was associated with a 56% mortality rate. CONCLUSION The short-term outcomes of VV and VA are comparable. Patients with CDH who fail VV may be predisposed to a worse outcome. Nevertheless, VV offers equal benefit to patients with CDH requiring ECMO while preserving the native carotid.

Abstract
Treatment of congenital diaphragmatic hernia (CDH) challenges obstetricians, pediatric surgeons, and neonatologists. Persistent pulmonary hypertension (PPHT) associated with lung hypoplasia in CDH leads to a high mortality rate at birth. PPHT is principally due to an increased muscularization of the arterioles. Management of CDH has been greatly improved by the introduction of prenatal surgical intervention with tracheal obstruction (TO) and by more appropriate postnatal care. TO appears to accelerate fetal lung growth and to increase the number of capillary vessels and alveoli. Improvement of postnatal care over the last years is mainly due to the avoidance of lung injury by applying low peak inflation pressure during ventilation. The benefits of other drugs or technical improvements such as the use of inhaled nitric oxide or extracorporeal membrane oxygenation (ECMO) are still being debated and no single strategy is accepted worldwide. Despite intensive clinical and experimental research, the treatment of newborn with CDH remains difficult.

Abstract
AIMS To compare surgical results for congenital diaphragmatic hernia (CDH) in two Scandinavian university hospitals and to evaluate the effects of abortions on the clinical profile of CDH in Iceland. METHODS A retrospective study including all CDH-cases in Iceland 1983-2002 and children referred to Lund University Hospital 1993-2002. Aborted fetuses with CDH from a nation-wide Icelandic abort-registry were also included. RESULTS In Iceland, 19 out of 23 children with CDH were diagnosed < 24 hours from delivery, one with associated anomalies. Eight fetuses were diagnosed prenatally and seven of them aborted, three having isolated CDH at autopsy. In Iceland, 15 of 18 children operated on survived surgery (83% operative survival). In Lund 28 children were treated with surgery, 23 of them diagnosed early after birth or prenatally. Four children did not survive surgery (86% operative survival) and 9 (31%) had associated anomalies. All the discharged children treated in Iceland and Lund are alive, 3-22 years postoperatively. CONCLUSION CDH is a serious anomaly where morbidity and mortality is directly related to other associated anomalies and pulmonary hypoplasia. However, majority of CDH patients do not have other associated anomalies. In spite of improved surgical results (operative mortality < 20%), a large proportion of pregnancies complicated with CDH are terminated. We conclude that the improved survival rate after corrective surgery must be emphasized when giving information to parents regarding abortion of fetuses with a prenatally diagnosed CDH.

Abstract
AIM The aim of this study was to determine the presence of the neuronal nitric oxide synthase (nNOS) in near full-term lambs with congenital diaphragmatic hernia (CDH) and its role in the modulation of pulmonary vascular basal tone. METHODS We surgically created diaphragmatic hernia on the 85th day of gestation. On the 135th, catheters were used to measure pulmonary pressure and blood flow. We tested the effects of 7-nitroindazole (7-NINA), a specific nNOS antagonist and of N-nitro-L-arginine (L-NNA), a nonspecific nitric oxide synthase antagonist. In vitro, we tested the effects of the same drugs on isolated pulmonary vessels. The presence of nNOS protein in the lungs was detected by Western blot analysis. RESULTS Neither 7-NINA nor L-NNA modified pulmonary vascular basal tone in vivo. After L-NNA injection, acetylcholine (ACh) did not decrease significantly pulmonary vascular resistance (PVR). In vitro, L-NNA increased the cholinergic contractile-response elicited by electric field stimulation (EFS) of vascular rings from lambs with diaphragmatic hernia. CONCLUSION We conclude that nNOS protein is present in the lungs and pulmonary artery of near full-term lamb fetuses with diaphragmatic hernia, but that it does not contribute to the reduction of pulmonary vascular tone at birth.

Abstract
Morgagni hernia (MH) is a congenital herniation of the abdominal organs through the subcostosternal portion of the diaphragm. It is a rare type of diaphragmatic hernia that has been associated with other congenital anomalies. The purpose of this clinical review was to determine the incidence of associated anomalies in patients with MH at a major pediatric referral center. The medical records of all patients with the diagnosis of MH were reviewed retrospectively between 1983 and 2006. The age, sex, side of herniation, presenting symptoms and signs, associated anomalies, radiologic features, intraoperative findings, postoperative course, complications, and mortality were recorded. There were 11 males and 5 females. The average age of the patients was 34.5 months (range 2 months-14 years). Twelve patients (75%) had at least one associated congenital malformation and eight (66.6%) of them had multiple anomalies. Six (37.5%) patients had a chromosomal anomaly, Down's syndrome in five and Turner syndrome in one. MH has a high incidence of associated congenital malformations.

Abstract
BACKGROUND Prenatal diagnosis and outcome of right congenital diaphragmatic hernia (RCDH) are far less well known than the more common left CDH (LCDH). In addition, onset of RCDH beyond the neonatal period with a spectrum of atypical symptoms is not unusual. A retrospective analysis of RCDH treated at a single center over 18 years has been reviewed with regard to outcome after the introduction of a new treatment protocol for CDH. METHODS All charts of patients with CDH between 1987 and 2004 were reviewed. Twenty-nine patients with RCDH were identified. The patients were divided into 2 historical groups: group 1, from 1987 to 1998 (16 patients), and group 2, from 1999 to 2004 (13 patients). From 1999, at the Department of Pediatric Surgery of Padua, the management of a baby born with CDH has been standardized and includes planned delivery at term, high-frequency oscillatory ventilation since birth, inhaled nitric oxide if required, extracorporeal membrane oxygenation as a "last resort," and delayed repair once the infant is hemodynamically stable. Patients with either prenatal diagnosis of RCDH or early onset of symptoms (<6 hours of life) were considered "high risk," and those with late onset (>6 hours) were considered "low risk." RESULTS Of 29 patients, prenatal diagnosis was available in 8 (27.5%) and major associated malformations in 8 patients (27.5%). Eight (50%) of 16 cases from group 1 and 9 (69.2%) of 13 cases from group 2 were high-risk patients. There was a trend in favor of a higher survival among high-risk patients from group 2 (25% vs 44%), although this was not statistically significant. As expected, all low-risk patients survived (P = .0001). Plain thorax x-ray was diagnostic in 23 (82.1%) cases, initially normal in 3, not performed in 1, and misinterpreted as right lower lobe pneumonia in 2. At operation, the prosthetic patch was required in 2 (9%) of 22 cases and the peritoneal sac was found in 4 (13.7%). CONCLUSIONS (1) The rate of prenatal diagnosis of RCDH was low and remained stable throughout the examined period. (2) The introduction of a treatment protocol, using high-frequency oscillatory ventilation since birth, improved the survival of high-risk patients with RCDH, although the data did not reach statistical significance. (3) The majority (75%) of low-risk patients presented beyond the first week of life with a variety of aspecific gastrointestinal or respiratory symptoms that accounted for initial misdiagnosis. (4) Even in these cases, the outcome was excellent.

Abstract
BACKGROUND Congenital diaphragmatic hernia (CDH) is a severe birth defect of unknown etiology. The aims of the current report were to extend the literature on the descriptive epidemiology of CDH and to determine whether its mortality rate decreased in California during the study period. METHODS Using data from a large population-based registry, we ascertained 631 CDH cases from 1989 to 1997. We also classified cases as isolated or nonisolated based on the presence and type of major accompanying malformations. Approximately 2.5 million live and stillbirths occurred during the ascertainment period. Multivariate Poisson regression analysis was applied to examine the time trend and risk factors. RESULTS The overall prevalence of CDH was 2.49 per 10,000 live and stillbirths and did not vary over the study period. Isolated cases, which accounted for 58% of cases, revealed a prevalence of 1.45 per 10,000. Heart malformations were the most frequent major anomalies accompanying CDH. We observed a lower risk of isolated CDH among blacks. Advanced maternal age groups had a higher risk for nonisolated CDH. Multiparous women tended to have a lower risk for nonisolated CDH. Male infants and multiple births had an increased risk for isolated and nonisolated CDH. Infant mortality was slightly decreased over the study period. CDH cases with additional anomalies had higher mortality rates than isolated cases. CONCLUSION Our observations add to the relatively few population-based descriptive epidemiologic studies of the prevalence and mortality, and maternal and infant characteristics of CDH.

Abstract
This report describes a case of prenatally diagnosed bilateral diaphragmatic hernia. At 22 weeks' gestation, ultrasound revealed a cystic structure behind the fetus's heart on the axial image at the level of the cardiac four-chamber view. This suggested a left-sided congenital diaphragmatic hernia with herniation of the stomach into the left hemithorax. However, the left-to-right midline shift of the heart was minimal, which is not typical of left-sided congenital diaphragmatic hernia. Throughout the 30th week of gestation, the right and left branches of the pulmonary artery were hypoplastic compared with the values in normal fetuses of the same gestational age. The presumptive diagnosis was bilateral congenital diaphragmatic hernia. A female newborn weighing 2900 g was delivered at 37 weeks' gestation, and she died at 7 h of age. An autopsy revealed large defects on both sides of the diaphragm. In conclusion, prenatal diagnosis of bilateral diaphragmatic hernia is possible with fetal sonography.

Abstract
OBJECTIVES There have been many recent reports of improved survival rates for congenital diaphragmatic hernia (CDH), largely derived from institution-based data. These are often flawed by case selection bias. The objectives of this study were to document the true incidence, management, and outcomes of CDH in a geographically defined population over a 12-year period and to determine the changing trends in these over time. We also sought to ascertain the prenatal and postnatal factors associated with morbidity and death among these infants. METHODS A retrospective study of all cases of CDH in Western Australia from 1991 to 2002 was conducted. Cases were identified from 5 independent databases within the Western Australian health network, including the Western Australian Birth Defects Registry. All fetuses and neonates diagnosed with CDH in Western Australia during this period were identified, including miscarriages, stillbirths, and terminations of pregnancies in which a diagnosis of fetal CDH had been made, as well as those diagnosed postnatally. Cases not known to involve CDH until diagnosis at autopsy were also included. Infants with diaphragmatic eventration were excluded from the study. Detailed information was obtained from review of maternal and infant medical records. RESULTS One hundred sixteen cases of CDH were identified. Of these, 71 (61%) infants were born alive and 37 survived beyond 1 year of age (52% of live-born infants, 32% of all cases of CDH). Pregnancies involving 38 (33%) fetuses were terminated electively, 4 (3%) fetuses were aborted spontaneously, and 3 (3%) fetuses were stillborn. Another major congenital anomaly was present in 54 (47%) cases. Twenty-one (18%) cases had other anomalies that were likely to be fatal. Of all cases with an additional major anomaly, 42 (78%) died. Twenty-seven (71%) of 38 fetuses for whom the pregnancy was terminated had another major anomaly. Twenty-three (32%) live-born infants had another major anomaly (4 of which were considered fatal conditions); however, this did not affect their survival rates. Fifty-three percent of cases were diagnosed prenatally, and 49% of these pregnancies were then terminated. Of live-born infants with prenatally diagnosed CDH, 10 (33%) survived beyond 1 year of age. The gestational age at diagnosis did not affect the survival rate for live-born infants. Postnatal diagnosis occurred in 55 (47%) cases. Of these, 41 (74%) case subjects were born alive and diagnosed on clinical grounds after birth. In the remaining 14 cases, the diagnosis was made in postmortem examinations of fetuses from pregnancies that were terminated for other reasons (8 cases) or after spontaneous abortion or stillbirth (5 cases). Significant differences were found between prenatally and postnatally diagnosed live-born infants. Among live-born infants, prenatal diagnosis was associated with a significantly reduced survival rate (33%, compared with 66% for postnatally diagnosed infants). Prenatally diagnosed live-born infants were of lower birth weight and were born at an earlier gestational age. There was no statistically significant difference between the 2 groups in the onset of labor (spontaneous or induced) or in the rate of elective cesarean sections. Prenatally diagnosed live-born infants were more likely to be delivered in a tertiary perinatal center and were intubated more commonly at delivery. No difference was found in the Apgar scores at either 1 or 5 minutes between the groups. Of 71 live-born infants, 37 (52%) survived to 1 year of age. The majority of deaths occurred within the first 7 days of life (44%). Preoperative air leaks occurred for 16 (22%) infants, of whom 14 (88%) died. Factors found to predict death of live-born infants included prenatal diagnosis, right-sided hernia, major air leak, earlier gestational age at birth, lower birth weight, and lower Apgar scores at 1 and 5 minutes. Over the course of the decade, there were significant increases in the proportion of cases in which the diagnosis of CDH was made with prenatal ultrasonography and in the number of live-born infants born at the tertiary perinatal center. The mortality rate for all cases, the mortality rate for live-born infants, and the proportion of pregnancies involving prenatally diagnosed cases that were terminated electively were all greater in the later epoch but not significantly so. CONCLUSIONS This was a comprehensive, population-based study of CDH, with full case ascertainment, large sample size, and complete outcome data for all cases. The majority of published studies of CDH examined specific patient populations, such as neonates referred to tertiary pediatric surgical centers. Invariably, those studies failed to detect the demise of cases with CDH before arrival at the referral center, whether through termination of pregnancy, in utero fetal demise, or postnatal death occurring before transfer. Exclusion of these cases from calculations of mortality rates results in significant case selection bias. In our study, 35% of live-born infants died before referral or transport. The population of infants reaching the tertiary surgical center represented only 40% of the total cases of CDH. Wide variations in reported survival rates occur throughout the literature. These differences reflect the influence of this case selection bias, as well as variable referral policies and management practices. For our study population, survival rates differed vastly depending on the subgroup analyzed. Ninety-two percent of postoperative infants survived beyond 1 year of age, as did 80% of infants who reached the surgical referral center. However, only 52% of live-born infants, 32% of all cases, and 16% of all prenatally diagnosed cases survived. Therefore, the overall mortality rate for this condition remains high, despite increased prenatal detection, transfer to tertiary institutions for delivery, and advances in neonatal care, and is influenced significantly by the rate of prenatal termination. In our study, 33% of all cases of CDH and 49% of prenatally diagnosed fetuses underwent elective termination of pregnancy. This large number of fetal terminations confounds the accurate assessment of the true outcomes of this condition.

Abstract
BACKGROUND Two severe birth defects, congenital diaphragmatic hernia (CDH) and esophageal atresia (EA) with or without tracheoesophageal fistula (TEF), have traditionally been analyzed separately in epidemiological studies. Lung hypoplasia (LH), part of the CDH spectrum, is not usually associated with EA/TEF, yet both are foregut malformations. METHODS We conducted an epidemiological study of two combinations of the defects in the population of 3,318,966 live births and stillbirths monitored from 1983 to 1996 by the California Birth Defects Monitoring Program (CBDMP). RESULTS A total of 433 cases had a Bochdalek type CDH/LH (0.13 per 1000 births), 893 had EA/TEF (0.27 per 1000 births), and 646 had LH (0.19 per 1000 births). Among them, 18 cases had CDH/LH with EA/TEF (0.005 per 1000 births), and 53 had EA/TEF and LH (0.02 per 1000 births); both prevalences are significantly higher than expected. Sixteen of 17 cases of CDH/LH with EA/TEF, and 34 of 40 cases of EA/TEF with LH were stillborn or died; 72% and 74%, respectively, had an autopsy. The male to female sex ratios were 1.43 and 1.13, respectively. In both groups, infants had similar proportions of additional severe defects, except for genitourinary and anal defects and syndromes/associations, which were more prevalent in the EA/TEF with LH group. We reviewed human studies and experimental animal models for factors reported to cause any combination of the defects. CONCLUSIONS Several genetic and environmental factors could affect the significant co-occurrence of the defects. Future studies should include storage of patients' biological materials for DNA analysis, karyotyping, and environmental exposure evaluation.

Abstract
BACKGROUND/PURPOSE Delayed presentation of congenital diaphragmatic hernia (CDH) has been considered rare, and clinical manifestations differ from the more common newborn entity. Associated malformations in late-appearing CDH have been reported in a few patients. The authors reviewed their clinical experience to catalogue the frequency and clinical importance of associated malformations in patients with late-presenting CDH. METHODS The records of patients greater than 1 month of age with Bochdalek type CDH treated in the authors' clinic, from 1991 to 2001, were retrospectively reviewed. Twenty patients (age range, 1 month to 10 years) were included in the study. RESULTS Associated malformations were documented in 16 of the patients (80%) and included malrotation in 12 patients, umbilical hernia in 2, pulmonary hypoplasia in 4, pulmonary sequestration in 1, gastroesophageal duplication cyst coexisting with polysplenia in 1, atrial septal defect and ventricular septal defect in 1, hydronephrosis in 1, wandering spleen in 1, talipes equinovarus in 1, and type I diabetes mellitus in 1. CONCLUSIONS The results of this study show a significant incidence and a wide spectrum of associated malformations. These findings suggest that patients with late CDH should be evaluated carefully for additional anomalies that may help to establish correct diagnosis and treatment.

Abstract
OBJECTIVE The prenatal differentiation of a fetal congenital diaphragmatic hernia from other echogenic chest masses can be difficult. The implications of the leading diagnosis can greatly affect the neonatal prognosis. The cases presented illustrate how the primary diagnosis of a fetal chest mass can change during the course of gestation as the appearance of the chest mass evolves. METHODS A descriptive analysis of 2 cases reviewed the importance of considering multiple causes of an echogenic chest mass. RESULTS The sonographic features of a congenital diaphragmatic hernia that have been described in the literature were not always present at the time of initial evaluation. CONCLUSIONS A congenital diaphragmatic hernia should be part of the differential diagnosis considered during consultation with parents whose fetus has an echogenic chest mass.

Abstract
PURPOSE The aim of this study was to review all available studies reported in the English-language literature from 1975 through 1998, and by meta-analysis assess the importance of prenatal diagnosis, associated malformations, side of hernia, timing of surgery, and study population on mortality rates in patients with congenital diaphragmatic hernia (CDH). METHODS One-hundred-two studies were identified, and 51 studies (2,980 patients) fulfilled the prespecified inclusion criteria. Studies were grouped according to study population into: (I) fetuses diagnosed prenatally; (II) neonates admitted to a treatment center; and (III) population-based studies. RESULTS Pooled total mortality rate was significantly higher in category I than in category III (75.6% v 58.2%, P < .001). Pooled hidden postnatal mortality rate (deaths before admittance to a treatment center) in population-based studies was 34.9%. Prenatally diagnosed patients in both category II and III had significantly higher mortality rates than those diagnosed postnatally. Mortality rates were significantly higher among CDH infants with associated major malformations compared with isolated CDH in all 3 categories. An increased mortality rate in right-sided CDH was found in category II and III. CONCLUSIONS Prenatal diagnosis of CDH, presence of associated major malformations, and the study population have a major influence on mortality rate. The very high mortality rate in studies of fetuses with a prenatal diagnosis of CDH should be taken into account in prenatal counselling.
