Gehle DB, Meyer LC, Jancelewicz T. The role of extracorporeal life support and timing of repair in infants with congenital diaphragmatic hernia. WORLD JOURNAL OF PEDIATRIC SURGERY 2024; 7:e000752. [PMID: 38645885 PMCID: PMC11029407 DOI: 10.1136/wjps-2023-000752] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/05/2023] [Accepted: 03/20/2024] [Indexed: 04/23/2024] Open
Abstract
Extracorporeal life support (ECLS) serves as a rescue therapy for patients with congenital diaphragmatic hernia (CDH) and severe cardiopulmonary failure, and only half of these patients survive to discharge. This costly intervention has a significant complication risk and is reserved for patients with the most severe disease physiology refractory to maximal cardiopulmonary support. Some contraindications to ECLS do exist such as coagulopathy, lethal chromosomal or congenital anomaly, very preterm birth, or very low birth weight, but many of these limits are being evaluated through further research. Consensus guidelines from the past decade vary in recommendations for ECLS use in patients with CDH but this therapy appears to have a survival benefit in the most severe subset of patients. Improved outcomes have been observed for patients treated at high-volume centers. This review details the evolving literature surrounding management paradigms for timing of CDH repair for patients receiving preoperative ECLS. Most recent data support early repair following cannulation to avoid non-repair which is uniformly fatal in this population. Longer ECLS runs are associated with decreased survival, and patient physiology should guide ECLS weaning and eventual decannulation rather than limiting patients to arbitrary run lengths. Standardization of care across centers is a major focus to limit unnecessary costs and improve short-term and long-term outcomes for these complex patients.

Abstract
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.

Early nitric oxide is not associated with improved outcomes in congenital diaphragmatic hernia. Pediatr Res 2023; 93:1899-1906. [PMID: 36725908 DOI: 10.1038/s41390-023-02491-8] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/30/2022] [Revised: 11/07/2022] [Accepted: 12/30/2022] [Indexed: 02/03/2023]
Abstract
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.

Long-Term Evaluation of Gastroesophageal Reflux in Neonates with and without Preventive Anti-reflux Surgery at the Time of Congenital Diaphragmatic Hernia Repair. CHILDREN 2022; 9:children9081137. [PMID: 36010028 PMCID: PMC9406490 DOI: 10.3390/children9081137] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/22/2022] [Revised: 07/12/2022] [Accepted: 07/21/2022] [Indexed: 11/21/2022]
Abstract
One potential comorbidity after congenital diaphragmatic hernia (CDH) is gastroesophageal reflux (GER), which can have a substantial effect on patients’ quality of life, thriving, and complications later in life. Efforts have been made to reduce gastroesophageal reflux with a preventive anti-reflux procedure at the time of CDH repair. In this follow-up study of neonates participating in a primary RCT study on preventive anti-reflux surgery, symptoms of GER were assessed longitudinally. Long-term data with a median follow-up time of ten years was available in 66 patients. Thirty-one neonates received an initial fundoplication. Secondary anti-reflux surgery was necessary in 18% and only in patients with large defects. It was required significantly more often in patients with intrathoracic herniation of liver (p = 0.015) and stomach (p = 0.019) and patch repair (p = 0.03). Liver herniation was the only independent risk factor identified in multivariate regression analysis. Primary fundopexy and hemifundoplication did not reveal a protective effect regarding the occurrence of GER symptoms, the need for secondary antireflux surgery or the gain of body weight regardless of defect size neither in the short nor in the long term. Symptoms of GER must be assessed carefully especially in children with large defects, as these are prone to require secondary anti-reflux surgery in the long-term. Routine evaluation of GER including endoscopy and impedance measurement should be recommended especially for high-risk patients.

Abstract
OBJECTIVE To measure the survival among comparable neonates with CDH supported with and without ECLS. SUMMARY OF BACKGROUND DATA Despite widespread use in the management of newborns with CDH, ECLS has not been consistently associated with improved survival. METHODS A retrospective cohort study was performed using ECLS-eligible CDH Study Group registry patients born between 2007 and 2019. The primary outcome was in-hospital mortality. Neonates who did and did not receive ECLS were matched based on variables affecting risk for the primary outcome. Iterative propensity score-matched, survival (Cox regression and Kaplan-Meier), and center effects analyses were performed to examine the association of ECLS use and mortality. RESULTS Of 5855 ECLS-eligible CDH patients, 1701 (29.1%) received ECLS. "High-risk" patients were best defined as those with a lowest achievable first-day arterial partial pressure of CO2 of ≥60 mm Hg. After propensity score matching, mortality was higher with ECLS (47.8% vs 21.8%, odds ratio 3.3, 95% confidence interval 2.7-4.0, hazard ratio 2.3, P < 0.0001). For the subgroup of high-risk patients, there was lower mortality observed with ECLS (64.2% vs 84.4%, odds ratio 0.33, 95% confidence interval 0.17-0.65, hazard ratio 0.33, P = 0.001). This survival advantage was persistent using multiple matching approaches. However, this ECLS survival advantage was found to occur primarily at high CDH volume centers that offer frequent ECLS for the high-risk subgroup. CONCLUSIONS Use of ECLS is associated with excess mortality for low- and intermediate-risk neonates with CDH. It is associated with a significant survival advantage among high-risk infants, and this advantage is strongly influenced by center CDH volume and ECLS experience.

Abstract
BACKGROUND The Severe Pulmonary Hypoplasia and Evaluation for Resuscitative Efforts (SPHERE) protocol was developed to attempt to identify CDH patients with likely lethal pulmonary hypoplasia. We present our experience with this protocol and utilize the CDH Registry to critically assess the protocol. METHODS SPHERE patients identified based on prenatal imaging (10/2009-1/2018) were offered ECMO if meeting postnatal physiologic criteria, while others received comfort measures. Within the CDH Registry, patients with suspected severe CDH were identified and separated into "passed" (lowest pCO2 ≤100) versus "failed" (lowest pCO2 >100) groups. RESULTS Of 23 SPHERE patients, 57% (13/23) passed criteria for ECMO and survival was 46% (6/13) in that cohort. Of 4912 patients in the CDH Registry, 265 met criteria. There was no difference in survival rates between those that "passed" (122/227; 54%) versus "failed" (18/38; 47%). However, the latter had longer ECMO runs and more required ventilator/ECMO support at 30 days. Amongst survivors, the "failed" group had longer hospital stays and more frequently required tube feeds at discharge. CONCLUSIONS The SPHERE protocol did not predict mortality in the CDH Registry. However, our data suggest resource utilization is significant when unable to reach pCO2 ≤100 despite resuscitation. Morbidity remains high in this group.

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
BACKGROUND Research concerning factors of death after neonatal surgery is scarce. Insight into mortality might improve perioperative care. This study aimed to identify predictive factors of mortality after neonatal surgery in a low income country (LIC). METHODS Charts of all newborn patients who underwent surgical procedures under general anesthesia during the neonatal period in our department of pediatric surgery between January 2010 and December 2017 were reviewed. We used univariate and multivariate analysis to evaluate perioperative variables potentially predictive of early postoperative mortality. RESULTS One hundred eighty-two cases were included in the study: 41 newborns (28.6%) were premature (<37 weeks of gestation) and 52 (22.5%) weighed less than 2.5 kg. The most commonly diagnosed conditions were esophageal atresia (24%) and bowel obstruction (19%). Forty-four patients (24%) died during hospitalization. The highest rate of mortality was observed for congenital diaphragmatic hernia. Univariate analysis showed that perinatal predictive variables of mortality were prematurity, low birth weight, the necessity of preoperative intubation, and duration of surgery more than 2 h. Logistic regression showed three independent risk factors, which are the duration of surgery, low birth weight and the necessity of preoperative intubation. CONCLUSION The overall mortality in infants undergoing neonatal surgery is still high in LICs. Knowledge of independent risk factors of early mortality may help clinicians to more adequately manage the high-risk population. TYPE OF THE STUDY Clinical research paper. LEVEL OF EVIDENCE III.

Abstract
BACKGROUND/PURPOSE The presence of lung injury and the factors that contribute to it in infants with congenital diaphragmatic hernia (CDH) have not been objectively measured during their clinical course. In adults with acute respiratory distress syndrome, higher serum levels of surfactant protein D (SP-D) are linked to lung injury and worse outcomes. We hypothesized that serum SP-D levels would be elevated in CDH infants and that the levels would correlate to the amount of lung injury present. METHODS In this retrospective cohort study, serum SP-D levels were analyzed in 37 CDH infants and 5 control infants using a commercially available enzyme-linked immunosorbent assay kit. RESULTS Infants with more severe CDH had a statistically significant increase (p < 0.001) in serum SP-D over their first month of life. SP-D levels in CDH infants were similar to control infants while on extracorporeal membrane oxygenation (ECMO) but were 2.5-fold higher (p = 0.03) than controls following ECMO termination. SP-D levels increased 1.6-fold following surgical repair of the diaphragm and were significantly higher in the second week following surgery when compared to pre-operative levels (p < 0.03). CONCLUSIONS These results demonstrate that CDH infants experience lung injury during the first week of life, around the time of surgery, and at the time of ECMO termination. Level II prognosis study.

J Pediatr Surg 2019; 54:2048-2052. [PMID: 30824238 DOI: 10.1016/j.jpedsurg.2018.11.022] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/09/2018] [Revised: 11/21/2018] [Accepted: 11/25/2018] [Indexed: 01/31/2023]
Abstract
BACKGROUND Support on Extracorporeal oxygenation membrane (ECMO) represents the last therapeutic option in the management of respiratory failure and pulmonary hypertension refractory to treatment in patients with congenital diaphragmatic hernia (CDH). AIM The objective of this work was to present our experience of all the cases of CDH that we have transported on ECMO. MATERIAL AND METHODS Medical records of patients, national and international, with CDH transported by our service on ECMO from 1997 to 2018 were reviewed. RESULTS During 22 years, we performed 40 ECMO transports of newborns with CDH, 39 primary and one secondary. In 10% (4/40) we transferred patients from their primary hospital after the implantation of cannulae and commencement of ECMO to another center abroad owing to the lack of beds in our unit. Twenty (50%) of the transports were from a foreign country. Median transport distance was 560 (428-1381) km and the median transport time was 4.5 (4.2-6.3) h. The mode of transport was ground ambulance in 20%, helicopter in 10%, fixed wing aircraft in 62.5% and ground ambulance in Freight aircraft in 7.5%. In 40% of the transports, 20 complications occurred. In one of every four transports with complications, more than one event occurred. Most frequent complication was loss of tidal volumes (35%) and in 30% of the complications another patient related event was recorded. Equipment failure occurred in 20%, and climate problems and transport vehicle problems in 15%. No deaths occurred during transport. Venoarterial ECMO was used in 39 of the 40 cases. Survival to discharge was 87% for the entire period and long-term survival was 77%. CONCLUSIONS Long and short distance interhospital transports of CDH patients on ECMO can be performed safely. Despite occurrence of adverse events, the risk of mortality is very low. The personnel involved must be highly competent in intensive care, physiology and physics of ECMO, cannulation, intensive care transport and air transport medicine. They must also be trained to recognize risk factors in these patients. LEVEL OF EVIDENCE III Retrospective cohort study.

Risk-stratification enables accurate single-center outcomes assessment in congenital diaphragmatic hernia (CDH). J Pediatr Surg 2019; 54:932-936. [PMID: 30792092 DOI: 10.1016/j.jpedsurg.2019.01.020] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/26/2019] [Accepted: 01/27/2019] [Indexed: 01/18/2023]
Abstract
BACKGROUND Management of CDH is highly variable from center to center, as are patient outcomes. The purpose of this study was to examine risk-stratified survival and extracorporeal membrane oxygenation (ECMO) rates at a single center, and to determine whether adverse outcomes are related to patient characteristics or management. METHODS A retrospective single-center review of CDH patients was performed, and outcomes compared to those reported by the CDH Study Group (CDHSG) registry. Patient demographics, disparities, and clinical characteristics were examined to identify unique features of the cohort. A model derived using the registry that estimates probability of ECMO use or death in CDH newborns was used to risk-stratify patients and assess mortality rates. Observed over expected (O/E) ECMO use rates were calculated to measure whether "excess" or "appropriate" ECMO use was occurring. RESULTS There were 81 CDH patients treated between 2004-2017, and 5034 in the CDHSG registry. Mortality in ECMO-treated patients was higher than the registry. Socioeconomic variables were not significantly associated with outcomes. The strongest predictors of mortality were ECMO use and early blood gas variables. The risk model accurately predicted ECMO use with a c-statistic of 0.79. Compared with the registry, the disparity in mortality rates was greatest for moderate-risk patients. O/E ECMO use was highest in low and moderate-risk patients. CONCLUSIONS ECMO use is a more consistent predictor of mortality than CDH severity at a single center, and there is relative overuse of ECMO in lower-risk patients. Risk stratification allows for more accurate institutional assessment of mortality and ECMO use, and other centers could consider such an adjusted analysis to identify opportunities for outcomes improvement.

Abstract
BACKGROUND The purpose of this study was to employ a novel ex vivo lung model of congenital diaphragmatic hernia (CDH) to determine how a mechanical compression affects early pulmonary development. METHODS Day-15 whole fetal rat lungs (n = 6-12/group) from nitrofen-exposed and normal (vehicle only) dams were explanted and cultured ex vivo in compression microdevices (0.2 or 0.4 kPa) for 16 h to mimic physiologic compression forces that occur in CDH in vivo. Lungs were evaluated with significance set at P < 0.05. RESULTS Nitrofen-exposed lungs were hypoplastic and expressed lower levels of surfactant protein C at baseline. Although compression alone did not alter the α-smooth muscle actin (ACTA2) expression in normal lungs, nitrofen-exposed lungs had significantly increased ACTA2 transcripts (0.2 kPa: 2.04 ± 0.15; 0.4 kPa: 2.22 ± 0.11; both P < 0.001). Nitrofen-exposed lungs also showed further reductions in surfactant protein C expression at 0.2 and 0.4 kPa (0.53 ± 0.04, P < 0.01; 0.69 ± 0.23, P < 0.001; respectively). Whereas normal lungs exposed to 0.2 and 0.4 kPa showed significant increases in periostin (POSTN), a mechanical stress-response molecule (1.79 ± 0.10 and 2.12 ± 0.39, respectively; both P < 0.001), nitrofen-exposed lungs had a significant decrease in POSTN expression (0.4 kPa: 0.67 ± 0.15, P < 0.001), which was confirmed by immunohistochemistry. CONCLUSIONS Collectively, these pilot data in a model of CDH lung hypoplasia suggest a primary aberration in response to mechanical stress within the nitrofen lung, characterized by an upregulation of ACTA2 and a downregulation in SPFTC and POSTN. This ex vivo compression system may serve as a novel research platform to better understand the mechanobiology and complex regulation of matricellular dynamics during CDH fetal lung development.

Abstract
PURPOSE This study assesses the impact of extracorporeal membrane oxygenation (ECMO) associated morbidities on long-term quality of life (QOL) outcomes. METHODS A single center, retrospective review of neonatal and pediatric non-cardiac ECMO survivors from 1/2005-7/2016 was performed. The 2012 Pediatric Quality of Life Inventory™ (PedsQL™) survey was administered. Clinical outcomes and QOL scores between groups were compared. RESULTS Of 74 patients eligible, 64% (35 NICU, 12 PICU) completed the survey. Mean time since ECMO was 5.5±3years. ECMO duration for venoarterial (VA) and venovenous (VV) were similar (median 9 vs. 7.5days, p=0.09). VA ECMO had higher overall complication rate (64% vs. 36%, p=0.06) and higher neurologic complication rate (52% vs. 9%, p=0.002). ECMO mode and ICU type did not impact QOL. However, patients with neurologic complications (n=15) showed a trend towards lower overall QOL (63/100±20 vs. 74/100±18, p=0.06) compared to patients without neurologic complications. A subset analysis of patients with ischemic or hemorrhagic intracranial injuries (n=13) had significantly lower overall QOL (59/100±19 vs. 75/100±18, p=0.01) compared to patients without intracranial injuries. CONCLUSION Neurologic complication following ECMO is common, associated with VA mode, and negatively impacts long-term QOL. Given these associations, when clinically feasible, VV ECMO may be considered as first line ECMO therapy. TYPE OF STUDY Retrospective review. LEVEL OF EVIDENCE II.

Abstract
AIM To prospectively evaluate cerebral perfusion after repair of congenital diaphragmatic hernia (CDH) and right-common-carotid-artery (rCCA) occlusion after extracorporeal membrane oxygenation (ECMO) therapy. PATIENTS AND METHODS A total of 29 2-year-old-children with a history of CDH repair underwent cerebral magnetic resonance perfusion imaging. In 14 patients, the rCCA was occluded after ECMO therapy. Fifteen patients with CDH without ECMO served as controls. Regional cerebral-blood-flow (rCBF) was measured cortically and subcortically in both hemispheres and compared intra-individually and between both groups. RESULTS Patients with rCCA-occlusion showed intra-individual side differences between hemispheres, with significantly lower subcortical perfusion of the right hemisphere and reduced cortical perfusion. In one-third of patients with rCCA-occlusion, rCBF of the right-hemisphere was reduced by more than 20% when compared to the left hemisphere. Despite intra-individual side differences, mean rCBF in patients with rCCA occlusion was not reduced compared to controls. CONCLUSION Beside intra-individual side differences, overall right hemisphere perfusion is sufficient after rCCA-occlusion due to collateral blood supply.

Abstract
Among congenital malformations, congenital diaphragmatic hernia (CDH) is distinguished by its relatively low occurrence rate, need for resource intensive, integrated multidisciplinary care, and widespread variation in practice and outcome. Although randomized controlled trials (RCTs) are considered the gold standard for generating evidence, they are poorly suited to the study of a condition like CDH due to challenges in illness severity adjustment, unpredictability in clinical course and the impact limitations of studying a single intervention at a time. An alternative to RCTs for comparative effectiveness research for CDH is the patient registry, which aggregates multi-institutional condition-specific patient level data into a large CDH-specific database for the dual purposes of collaborative research and quality improvement across participating sites. This article discusses patient registries from the perspective of structure, data collection and management, and privacy protection that guide the use of registry data to support collaborative, multidisciplinary research. Two CDH-specific registries are described as illustrative examples of the "value proposition" of registries in improving the evidence basis for best practices for CDH.

Abstract
Despite wide use and decades of experience, survival of congenital diaphragmatic hernia (CDH) patients treated with extra-corporeal membrane oxygenation (ECMO), as reported by the extra-corporeal life support organization (ELSO), remains unchanged at 50%. High-survival rates both with and without utilizing ECMO have been reported, fueling questions about the utility of ECMO support in this difficult population. This review looks at data from the Congenital Diaphragmatic Hernia Study Group and individual center reports, to evaluate the role of ECMO in CDH, focusing on defining the patients most likely to benefit, and discussing how those benefits can best be achieved. These data show that ECMO improves survival in those CDH patients who are most severely affected, but potential complications of ECMO delivery outweigh benefit in patients with less severely affected. Improved results can be expected by minimizing ECMO complications, and by improving rates of CDH repair in patients that require ECMO.

Abstract
BACKGROUND/PURPOSE Extracorporeal membrane oxygenation (ECMO) is a treatment option for stabilizing neonates with congenital diaphragmatic hernia (CDH) in a critical condition when standard therapy fails. However, the use of this approach in Taiwan has not been previously reported. METHODS The charts of all neonates with CDH treated in our institute during the period 2007-2014 were reviewed. After 2010, patients who could not be stabilized with conventional treatment were candidates for ECMO. We compared the demographic data of patients with and without ECMO support. The clinical course and complications of ECMO were also reviewed. RESULTS We identified 39 neonates with CDH with a median birth weight of 2696 g (range, 1526-3280 g). Seven (18%) of these patients required ECMO support. The APGAR score at 5 minutes differed significantly between the ECMO and non-ECMO groups. The survival rate was 84.6% (33/39) for all CDH patients and 57.1% (4/7) for the ECMO group. The total ECMO bypass times in the survivors was in the range of 5-36 days, whereas all nonsurvivors received ECMO for at least 36 days (mean duration, 68 days). Surgical bleeding occurred in four of seven patients in the ECMO group. CONCLUSION The introduction of ECMO rescued some CDH patients who could not have survived by conventional management. Prolonged (i.e., > 36 days) ECMO support had no benefit for survival.

Abstract
AIM To discuss the chronological changes observed in a national survey of neonatal surgery in Japan performed every 5 years by the Committee in the Japanese Society of Pediatric Surgeons. METHODS We analyzed the data obtained for 20 years from 1993 to 2013 and herein report the chronological changes. RESULTS The number of summarized cases was least in 1993, with 2806 cases, and subsequently increased to 3753 cases in 2013. The mortality rate among the patients with maternal transport linearly decreased (p = 0.0386). Although the proportion of extremely low birth weight infants linearly increased (p = 0.0014), with an annual rate of +0.39 %, the mortality rate linearly decreased (p = 0.0010), with an annual rate of -1.68 %. Moreover, the overall mortality rate linearly decreased (p = 0.0002), with an annual rate of -0.26 %. Most diseases were observed to exhibit a decline in the mortality rate with the same trend as overall mortality. The decline in the mortality rate was most robust with respect to congenital diaphragmatic hernia (CDH). The mortality rates, except for that of CDH, omphalocele, esophageal atresia, and intestinal perforation, declined to 5 % or lower by 2013. CONCLUSIONS The present findings may be the result of remarkable progress in perinatal management.

Abstract
PURPOSE Centers that care for newborns with congenital diaphragmatic hernia (CDH) may impose selection criteria for offering or limiting aggressive support in those patients most severely affected. The purpose of this study was to analyze outcomes in newborns with highly severe CDH uniformly treated for survival. METHODS We reviewed 172 consecutive inborn patients without associated lethal anomalies treated at a single institution with a dedicated CDH program. Survival, respiratory outcome, and time to discharge in the most severe 10% (or fewer) of patients based on the physiologic measures of 5-minute Apgar, CDH Study Group (CDHSG) predicted survival, need for ECMO in the first 6 hours, and need for ECMO in the first 3 hours of life were studied. We also identified patients with best PaCO2 greater than 100 and best pH less than 7.0. A multivariate model (AUC-0.92) predicting mortality was also used to define the most severe 10%. RESULTS Of 172 consecutive inborn patients, 18 had a 5-minute Apgar of 3 or less, and 11 survived (61%), 10 had a 5-minute Apgar of 2 or less, and 6 survived (60%), and 6 had a 5-minute Apgar of 1 or less, and 4 survived (67%). Seventeen had a CDHSG predicted survival less than 25%, and 9 survived (53%). Thirteen of 172 required ECMO for rescue in the first 6 hours of life, and 9 survived (69%), including 7 in the first 3 hours, and 5 survived (71%). Despite focused resuscitation in the delivery room and high levels of ventilatory support, 22 patients had a best PCO2 greater than 100 and best pH less than 7.0 for 1 hour or longer. Twelve of these 22 survived to discharge (55%). Of 17 defined by multivariate predictive modeling as the most severe, 8 survived (47%) with zero of the 3 ECMO ineligible prematures surviving. Of the 16 (10%) most severe ECMO-eligible patients, 10 of 16 survived (63%). All survivors were discharged home on no ventilatory support greater than nasal cannula oxygen. CONCLUSION In newborn CDH patients without lethal associated anomalies, accepted measures of physiologic severity failed to predict mortality. Survival met or exceeded 50% even in the most severe 10% as defined by these measures. These data support the practice of treating each patient for survival regardless of the physiologic severity in the first hours of life, and selection criteria for not offering ECMO should be reevaluated where practiced.

Abstract
The Congenital Diaphragmatic Hernia Study Group (CDHSG) is an international consortium of centers that prospectively collect and voluntarily contribute data about live-born CDH patients they manage. These data are compiled to form a registry from which any participating center may utilize the dataset to answer specific clinical questions and monitor outcomes. Since its inception in 1995, 112 centers have participated (including 66 centers from 13 countries currently active), data on more than eight thousand total children have been collected, and 35 manuscripts have been generated using registry data. This review covers the formation and structure of the CDH study group and registry, including function, center involvement, and the evolution of data collection. We also review reports generated by the CDHSG, with particular focus on the work after 2008. International multicenter consortiums, such as the CDHSG, allow physicians that manage uncommon, complex, heterogeneous diseases to develop evidence-based hypotheses and conclusions for clinical questions.

Growth in children with congenital diaphragmatic hernia during the first year of life. J Pediatr Surg 2014; 49:1363-6. [PMID: 25148738 DOI: 10.1016/j.jpedsurg.2014.02.081] [Citation(s) in RCA: 31] [Impact Index Per Article: 3.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/24/2013] [Revised: 01/06/2014] [Accepted: 02/12/2014] [Indexed: 11/20/2022]
Abstract
PURPOSE Infants with congenital diaphragmatic hernia (CDH) have high rates of mortality and long-term morbidity, including poor growth and failure to thrive. The aim of this study was to describe growth patterns during the first year of life in infants with congenital diaphragmatic hernia in a non-ECMO cohort. METHODS Medical records of infants with CDH admitted to our center between January 2005 and December 2011 were reviewed. Infants with anthropometric measurements at 3, 6 and 12months were included. Anthropometric measurements were obtained for the first year of life. Logistic regression analyses were performed to find predictive associations with failure to thrive (FTT). RESULT Of the 45 survivors, 38 were seen twice (84%) and 24 (53%) were seen on three occasions to age 12months. Poor growth was observed with weight being most affected. FTT was present in 63% during the first six months of life. Days of mechanical ventilation were the only predictor of FTT. Besides poor weight gain, height and head circumference were also reduced. However, catch-up growth occurred during the second half of infancy and at age 12months failure to thrive had reduced by two thirds to 21%. CONCLUSIONS Poor growth is a common early finding in CDH patients, which improves during infancy. This emphasizes the importance of close follow-up and aggressive nutritional management in CDH patients.

Abstract
Congenital diaphragmatic hernia is an uncommon congenital anomaly of the diaphragm with pulmonary hypoplasia and persistent pulmonary hypertension as serious consequences. Despite recent advances in therapy, congenital diaphragmatic hernia remains a challenging condition. Best treatment strategies are still largely unknown, and practice strategies vary widely among different centres. Additionally, as congenital diaphragmatic hernia is a relatively uncommon condition, it is difficult to recruit sufficient numbers of patients for clinical trials. In recent years, survival rates of congenital diaphragmatic hernia patients appear to have increased. With the progressively improved survival rates, the long-term prognosis and quality of life of patients have become an increasingly important issue. Survivors have been shown to be at risk for many long-term morbidities, which highlights the importance of long-term follow-up of these children. The aim of this review is to give an overview of the current knowledge regarding congenital diaphragmatic hernia.

Abstract
PURPOSE Recent experimental work suggests the therapeutic role of mesenchymal stromal cells (MSCs) during lung morphogenesis. The purpose of this study was to investigate the potential paracrine effects of amniotic fluid-derived MSCs (AF-MSCs) on fetal lung growth in a nitrofen explant model. METHODS Pregnant Sprague-Dawley dams were gavage fed nitrofen on gestational day 9.5 (E9.5). E14.5 lung explants were subsequently harvested and cultured ex vivo for three days on filter membranes in conditioned media from rat AF-MSCs isolated from control (AF-Ctr) or nitrofen-exposed (AF-Nitro) dams. The lungs were analyzed morphometrically and by quantitative gene expression. RESULTS Although there were no significant differences in total lung surface area among hypoplastic lungs, there were significant increases in terminal budding among E14.5+3 nitrofen explants exposed to AF-Ctr compared to explants exposed to medium alone (58.8±8.4 vs. 39.0±10.0 terminal buds, respectively; p<0.05). In contrast, lungs cultured in AF-Nitro medium failed to augment terminal budding. Nitrofen explants exposed to AF-Ctr showed significant upregulation of surfactant protein C to levels observed in normal fetal lungs. CONCLUSIONS AF-MSCs can augment branching morphogenesis and lung epithelial maturation in a fetal explant model of pulmonary hypoplasia. Cell therapy using donor-derived AF-MSCs may represent a novel strategy for the treatment of fetal congenital diaphragmatic hernia.

Abstract
OBJECTIVES The purpose of this study was to compare different methods for measuring the fetal lung area-to-head circumference ratio and to investigate their prediction of postpartum survival and the need for neonatal extracorporeal membrane oxygenation (ECMO) therapy in fetuses with isolated congenital diaphragmatic hernias. METHODS This prospective study included 118 fetuses of at least 20 weeks' gestation with isolated left-sided congenital diaphragmatic hernias. The lung-to-head ratio was measured with 3 different methods (longest diameter, anteroposterior diameter, and tracing). To eliminate the influence of gestational age, the observed-to-expected lung-to-head ratio was calculated. Receiver operating characteristic (ROC) curves were calculated for the statistical prediction of survival and need for ECMO therapy by the observed-to-expected lung-to-head ratio measured with the different methods. RESULTS For survival and ECMO necessity 118 and 102 cases (16 neonates were not eligible for ECMO) were assessed, respectively. For prediction of postpartum survival and ECMO necessity, the areas under the ROC curves and 95% confidence intervals showed very similar results for the 3 methods for prediction of survival (tracing, 0.8445 [0.7553-0.9336]; longest diameter, 0.8248 [0.7360-0.9136]; and anteroposterior diameter, 0.8002 [0.7075-0.8928]) and for ECMO necessity (tracing, 0.7344 [0.6297-0.8391]; longest diameter, 0.7128 [0.6027-0.8228]; and anteroposterior diameter, 0.7212 [0.6142-0.8281]). Comparisons between the areas under the ROC curves showed that the tracing method was superior to the anteroposterior diameter method in predicting postpartum survival (P = .0300). CONCLUSIONS Lung-to-head ratio and observed-to-expected lung-to-head ratio measurements were shown to accurately predict postnatal survival and the need for ECMO therapy in fetuses with left-sided congenital diaphragmatic hernias. Tracing the limits of the lungs seems to be the favorable method for calculating the fetal lung area.

Abstract
OBJECTIVES To compare different rotation angles for assessment of fetal lung volume by 3-dimensional (3D) sonography with magnetic resonance imaging (MRI) regarding prediction of mortality and the need for neonatal extracorporeal membrane oxygenation (ECMO) therapy in fetuses with congenital diaphragmatic hernias. METHODS One hundred patients with fetal congenital diaphragmatic hernias between 22 and 39 weeks' gestation were examined by 3D sonography and MRI. Sonographic contralateral fetal lung volumes were assessed by the rotational technique (virtual organ computer-aided analysis) at 3 different rotation angles: 6°, 15°, and 30°. The MRI fetal lung volumes were calculated based on multiplanar T2-weighted MRI. To eliminate the influence of gestational age, the observed to expected contralateral fetal lung volume on sonography and the observed to expected fetal lung volume on MRI were calculated. Receiver operating characteristic (ROC) curves were calculated for the statistical prediction of survival and need for ECMO therapy by the observed to expected contralateral fetal lung volume (sonography) and observed to expected fetal lung volume (MRI). RESULTS One hundred cases were assessed for survival and 89 for ECMO necessity (11 neonates were not eligible for ECMO). For prediction of postpartum survival and ECMO necessity, the areas under the ROC curves (AUCs) showed very similar results for MRI and 3D sonography: observed to expected fetal lung volume by MRI, 0.819 (95% confidence interval, 0.730-0.909) and 0.835 (0.748-0.922), respectively; 6° sonography, 0.765 (0.647-0.883) and 0.820 (0.734-0.905); 15° sonography, 0.784 (0.672-0.896) and 0.811 (0.719-0.903); and 30° sonography, 0.732 (0.609-0.855) and 0.772 (0.671-0.872). Comparisons between the AUCs revealed no statistical differences. CONCLUSIONS We have shown the good prognostic value of 3D sonography in fetuses with congenital diaphragmatic hernias compared with MRI, particularly when using small rotation angles. Therefore, it can be an appropriate diagnostic tool when counseling patients for congenital diaphragmatic hernias.

Abstract
BACKGROUND During the last decade, new supportive modalities and new therapeutic strategies to treat congenital diaphragmatic hernia (CDH) have been introduced. In Japan, the large number of hospitals prevents centralizing infants with CDH in tertiary centers. The aim of this study was to evaluate the correlations between the number of CDH patients, survival rates, and the current strategies employed to treat CDH at the individual hospitals. METHODS Eighty-three hospitals with 674 CDH cases were analyzed using questionnaires. We classified the hospitals into three groups according to the number of CDH patients treated: Group 1 (G1; more than 21 patients), Group 2 (G2; 11-20 patients), and Group 3 (G3; fewer than 10 patients). RESULTS The median number of CDH patients in G1, G2, and G3 were 28, 14, and 4, respectively. The overall survival rate was 74.5%. When only the isolated CDH cases with a prenatal diagnosis were included, the overall survival rate was 79.3%. The survival rate of isolated CDH cases with a prenatal diagnosis was significantly higher in G1 than that in G2 or G3 (87.2% vs 75.2% vs 74.3%; P < 0.001). There were no differences in perinatal therapeutic strategies among the three groups. CONCLUSIONS We concluded that it might therefore be important to centralize infants with CDH, especially those with isolated CDH with a prenatal diagnosis, to tertiary centers in Japan in order to improve the survival rates.

Abstract
BACKGROUND/PURPOSE Congenital diaphragmatic hernia (CDH) remains a defiant challenge for pediatric surgeons. Since 2003, we developed a new protocol aiming for the better outcome. In this study, the usefulness of our new protocol was evaluated. MATERIALS AND METHODS Forty-six neonates with CDH at the age of less than 24 h were divided into two groups based on the difference of era and treatment protocols. In Group 1, 15 patients were treated between 1997 and 2002 and 31 patients were treated between 2003 and 2011 in Group 2. In the latter group, a new protocol was introduced focusing on the prevention of lung edema as well as lung injury by steroid administration and on the stabilization of cardiopulmonary function using continuous D-mannitol infusion. The survival rate and the postoperative intubation period (POIP) were compared between the two groups. RESULTS The overall survival rate was significantly increased from 53 % (8/15) to 81 % (25/31) (p < 0.05). In isolated CDH, the survival rate was increased from 58 to 93 %. The average POIP was remarkably shortened from 39.0 to 4.4 days (p < 0.01). CONCLUSION Our new protocol remarkably improved the survival rate and shortened the period of mechanical ventilation in neonates with CDH.

Abstract
OBJECTIVE To evaluate the impact of associated heart defects on outcomes to discharge, and identify factors affecting survival of all infants born with congenital diaphragmatic hernia (CDH) in last decade using Congenital Diaphragmatic Hernia Study Group data. STUDY DESIGN This was a retrospective review of all infants with CDH enrolled in Congenital Diaphragmatic Hernia Study Group database from January 2000 to December 2010. The study cohort was divided into 3 groups (GRP): GRP 1, CDH with major heart defects; GRP 2, CDH with minor heart defects; and GRP 3, CDH with no reported heart defects. RESULTS The 4268 enrolled infants included 345 (8%) in GRP 1, 412 (10%) in GRP 2, and 3511 (82%) in GRP 3. Survival was significantly lower in GRP 1 compared with GRP 2 and GRP 3 (36% vs 73%). In GRP 1, the most common defects were left heart obstructive lesions (34%). Survival was lowest in infants with transposition of great arteries (0%) and single ventricle physiology (16%). There was no change in survival rate for any group between 2000-2005 and 2006-2010. In GRP 1, factors that predicted lower survival were birth weight <2.5 kg, associated noncardiac anomalies, single ventricle physiology, no sildenafil therapy, no CDH repair, and no cardiac repair. CONCLUSION Survival is significantly lower in patients with CDH and major heart defects compared with patients with minor or no heart defects. Outcomes of newborns with CDH and major heart defects have not improved over the last decade.

Abstract
PURPOSE Congenital diaphragmatic hernia (CDH) remains a challenging and life-threatening congenital anomaly. The aim was to evaluate whether treatment and survival has changed during the last decade. METHODS We retrospectively analysed all consecutive infants with CDH referred to two European tertiary paediatric surgical centres over 11 years (January 1999 to December 2009). Minimum follow-up was 1 year. χ(2) test for trend was used to evaluate significance. RESULTS There were 234 infants. There was no significant variation over time in the proportion of infants receiving high frequency oscillatory ventilation (HFOV) (p = 0.89), inhaled nitric oxide (iNO) (p = 0.90) or extracorporeal membrane oxygenation (ECMO) (p = 0.22). 205 infants (88 %) were stabilised and underwent surgical repair; of these, 186 (79 %) survived after surgery. Over time there was a significant increase in the proportion of infants undergoing surgical repair (p = 0.018) without a concomitant significant improvement in survival (p = 0.099). CONCLUSION This multicentre analysis indicates that the survival rate of infants with CDH referred to two European paediatric surgical centres is high (79 %). The use of HFOV, iNO and ECMO has not changed in recent years. We observed a significant increase in the proportion of infants who undergo surgery but this has not resulted in a significant increase in the overall survival rate.

Abstract
Congenital diaphragmatic hernia (CDH) is associated with significant mortality due to lung hypoplasia and pulmonary hypertension. The role of embryonic pulmonary innervation in normal lung development and lung maldevelopment in CDH has not been defined. We hypothesize that developmental defects of intrapulmonary innervation, in particular autonomic innervation, occur in CDH. This abnormal embryonic pulmonary innervation may contribute to lung developmental defects and postnatal physiological derangement in CDH. To define patterns of pulmonary innervation in CDH, human CDH and control lung autopsy specimens were stained with the pan-neural marker S-100. To further characterize patterns of overall and autonomic pulmonary innervation during lung development in CDH, the murine nitrofen model of CDH was utilized. Immunostaining for protein gene product 9.5 (a pan-neuronal marker), tyrosine hydroxylase (a sympathetic marker), vesicular acetylcholine transporter (a parasympathetic marker), or VIP (a parasympathetic marker) was performed on lung whole mounts and analyzed via confocal microscopy and three-dimensional reconstruction. Peribronchial and perivascular neuronal staining pattern is less complex in human CDH than control lung. In mice, protein gene product 9.5 staining reveals less complex neuronal branching and decreased neural tissue in nitrofen-treated lungs from embryonic day 12.5 to 16.5 compared with controls. Furthermore, nitrofen-treated embryonic lungs exhibited altered autonomic innervation, with a relative increase in sympathetic nerve staining and a decrease in parasympathetic nerve staining compared with controls. These results suggest a primary defect in pulmonary neural developmental in CDH, resulting in less complex neural innervation and autonomic imbalance. Defective embryonic pulmonary innervation may contribute to lung developmental defects and postnatal physiological derangement in CDH.

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
The management of congenital diaphragmatic hernia (CDH) is undergoing continual change and refinement, fuelled by recent advances in this field. Although many studies have documented the benefits of these recent advances but definite recommendations are lacking. Also, injudicious use of some of these strategies may be counterproductive, underscoring the importance of evidence based treatment strategy. This article discusses the utility of the recent advances in the management of CDH.

Abstract
The practise of evidence based medicine means integrating the clinical expertise with the best available external clinical evidence from systematic research. There is a lack of supporting scientific evidence from rigorous trials in neonatal surgery. The indications for surgery and the type of operation performed in neonates are rarely supported by randomised controlled trials. As a consequence, the majority of the operations performed in neonates are supported by retrospective studies and surgeon preference. This review article is focussed on operations in neonates which are performed by general paediatric surgeons. Only a few randomised controlled trials have been performed in neonatal diseases such as congenital diaphragmatic hernia, necrotizing enterocolitis, pyloric stenosis and inguinal hernia. All of these trials have been based on collaboration between paediatric surgical units highlighting the importance of creating a network of centres that will promote multicentre prospective studies.

Congenital diaphragmatic hernia requiring extracorporeal membrane oxygenation: does timing of repair matter? J Pediatr Surg 2009; 44:1165-71; discussion 1171-2.

Abstract
PURPOSE Severe congenital diaphragmatic hernia (CDH) requiring extracorporeal membrane oxygenation (ECMO) is associated with high mortality. Timing of CDH repair relative to ECMO therapy remains controversial. Our hypothesis was that survival would significantly differ between those who underwent repair during ECMO and those who underwent repair after ECMO therapy. METHODS We examined deidentified data from the CDH study group (CDHSG) registry from 1995 to 2005 on patients who underwent repair and ECMO therapy (n = 636). We used Cox regression analysis to assess differences in survival between those who underwent repair during and after ECMO. RESULTS Five covariates were significantly associated with mortality as follows: timing of repair relative to ECMO (P = .03), defect side (P = .01), ECMO run length (P < .01), need for patch repair (P = .03), birth weight (P < .01), and Apgar score at 5 minutes (P = .03). Birth year, inborn vs transfer status, diaphragmatic agenesis, age at repair, and presence of cardiac or chromosomal abnormalities were not associated with survival. Repair after ECMO therapy was associated with increased survival relative to repair on ECMO (hazard ratio, 1.407; P = .03). CONCLUSION These data suggest that CDH repair after ECMO therapy is associated with improved survival compared to repair on ECMO, despite controlling for factors associated with the severity of CDH.

Abstract
Congenital diaphragmatic hernia (CDH) is a life-threatening anomaly with a mortality rate of approximately 40-50%, depending on case selection. It has been suggested that new therapeutic modalities such as nitric oxide (NO), high frequency oxygenation (HFO) and extracorporal membrane oxygenation (ECMO) might decrease mortality associated with pulmonary hypertension and the sequelae of artificial ventilation. When these new therapies indeed prove to be beneficial, a larger number of children with severe forms of CDH might survive, resulting in an increase of CDH-associated complications and/or consequences. In follow-up studies of infants born with CDH, many complications including pulmonary damage, cardiovascular disease, gastro-intestinal disease, failure to thrive, neurocognitive defects and musculoskeletal abnormalities have been described. Long-term pulmonary morbidity in CDH consists of obstructive and restrictive lung function impairments due to altered lung structure and prolonged ventilatory support. CDH has also been associated with persistent pulmonary vascular abnormalities, resulting in pulmonary hypertension in the neonatal period. Long-term consequences of pulmonary hypertension are unknown. Gastro-esophageal reflux disease (GERD) is also an important contributor to overall morbidity, although the underlying mechanism has not been fully understood yet. In adult CDH survivors incidence of esophagitis is high and even Barrett's esophagus may ensue. Yet, in many CDH patients a clinical history compatible with GERD seems to be lacking, which may result in missing patients with pathologic reflux disease. Prolonged unrecognized GERD may eventually result in failure to thrive. This has been found in many young CDH patients, which may also be caused by insufficient intake due to oral aversion and increased caloric requirements due to pulmonary morbidity. Neurological outcome is determined by an increased risk of perinatal and neonatal hypoxemia in the first days of life of CDH patients. In patients treated with ECMO, the incidence of neurological deficits is even higher, probably reflecting more severe hypoxemia and the risk of ECMO associated complications. Many studies have addressed the substantial impact of the health problems described above, on the overall well-being of CDH patients, but most of them concentrate on the first years after repair and only a few studies focus on the health-related quality of life in CDH patients. Considering the scattered data indicating substantial morbidity in long-term survivors of CDH, follow-up studies that systematically assess long-term sequelae are mandatory. Based on such studies a more focused approach for routine follow-up programs may be established.

Abstract
Significant advances in the postnatal management of patients with congenital diaphragmatic hernia (CDH) have resulted in a remarkable improvement in survival rates over the past two decades. The success of current postnatal management of CDH patients has rendered fetal intervention to be limited to the most severe cases, and the role for prenatal treatment of CDH patients remains unclear. The adoption of lung-preserving strategies including high-frequency oscillatory ventilation (HFOV) and extracorporeal membrane oxygenation (ECMO) have improved CDH outcomes especially in those patients with significant ventilatory or circulatory compromise. Survival rates of up to 90% are being reported in some high-volume centers. However, the increased survival in CDH patients has been accompanied by an increase in neurological, nutritional and musculoskeletal morbidity among the long-term survivors. This has resulted in the need to provide resources for the long-term follow-up and support of this patient population. In this article, the postnatal management strategies and primary and secondary outcomes of high-volume international pediatric surgical centers will be reviewed. Finally, the role of a multidisciplinary management team for the follow-up of long-term CDH survivors will be discussed.

Abstract
AIM Prostaglandin-E1 (PGE1) is used at most centers for treating pulmonary hypertension (PH) in congenital diaphragmatic hernia (CDH) because it has been regarded as effective. The aim of this study was to investigate the role of PGE1 for treating PH in CDH. METHODS We reviewed 49 CDH cases with echocardiography-proven PH. PH was treated with PGE1 and nitric oxide (NO) and high frequency oscillatory ventilation (HFOV) from 1997 to 2001 (PG + NO; n = 19) and with NO and HFOV from 2002 to 2007 (NO; n = 30). RESULTS Subject demographics, severity of PH, and presence of other anomalies were not significantly different between the two groups. In the PG + NO group, 12/19 (63.2%) survived (PG + NO-s) and 7/19 (36.8%) died (PG + NO-d). In the NO group, 21/30 (70.0%) survived (NO-s) and 9/30 (30.0%) died (NO-d). Survival rates were not significantly different. In the NO-s group, spontaneous closure of the ductus arteriosus (DA) was significantly earlier compared with the PG + NO-s group (P < 0.01; 4.0 +/- 0.9 vs. 9.5 +/- 2.2 days after birth). DA diameters were significantly larger in groups that died compared with groups that survived (P < 0.01), and PH persisted in groups that died. In the NO-s group, surgery was possible significantly earlier compared with the PG + NO-s group (P < 0.01; 3.75 +/- 0.67 vs. 6.12 +/- 0.78 days after birth). No NO-s case developed a PH crisis even though PGE1 was not used. Hospital stay was significantly shorter in the NO-s group compared with the PG + NO-s group (P < 0.05; 39.9 +/- 19 vs. 53.2 +/- 23 days). CONCLUSION Nitric oxide alone would appear to simplify the management of CDH with PH and provide better outcome.

NKCC-1 and ENaC are down-regulated in nitrofen-induced hypoplastic lungs with congenital diaphragmatic hernia. Pediatr Surg Int 2008; 24:993-1000.

Abstract
Congenital diaphragmatic hernia (CDH) is accompanied by pulmonary hypoplasia and pulmonary hypertension. Fetal lung growth is dependent on the secretion of lung liquid, which normally is absorbed at partus. The ion channel NKCC-1 is involved in this secretory process, but has recently also been reported to be implicated in absorption. CDH patients show a disturbed transition from secretion to absorption. alpha- and beta-ENaC are essential for lung liquid absorption. Common for all transcellular ion transport is the need for Na/K-ATPase as a primary driving force. The aim of the study was first to map the normal pulmonary expression of the above proteins during late gestation and secondly to see if the expression was affected in a CDH rat model. Pregnant Sprague-Dawley rat dams were given nitrofen on gestational day 9.5 to induce CDH. The fetuses were removed on gestational days E18 and E21. In addition, newborn rats were harvested postpartum on day P2. The fetuses were put into one of two groups: hypoplastic lungs without CDH (N-CDH) and hypoplastic lungs with CDH (N+CDH). The pulmonary expression of NKCC-1, alpha-/beta-ENaC and Na/K-ATPase was then analyzed using Western blot. We found that the protein levels of NKCC-1 on gestational days E18 and E21 were significantly lower among fetuses with N+CDH as well as N-CDH compared to controls. The expression of beta-ENaC was also significantly down-regulated in both the groups on E18 and E21. The protein levels of alpha-ENaC and Na/K-ATPase were not found to be significantly decreased, but both showed a tendency towards down-regulation. The marked down-regulation of NKCC-1 in fetal hypoplastic lungs with CDH indicates a possibly decreased lung liquid production. This may be one of the mechanisms behind the disturbed pulmonary development in CDH. We also show that beta-ENaC is down-regulated. Down-regulation of beta-ENaC may result in abnormal lung liquid absorption, which could be one of the mechanisms behind the respiratory distress seen in CDH patients postpartum.

Abstract
PURPOSE To prospectively assess the results of logistic regression analysis that were based on magnetic resonance (MR) image fetal lung volume (FLV) measurements to predict survival and the corresponding need for extracorporeal membrane oxygenation (ECMO) therapy in fetuses with congenital diaphragmatic hernia (CDH) before and after 30 weeks gestation. MATERIALS AND METHODS Written informed consent was obtained and the study was approved by the local research ethics committee. FLV was measured on MR images in 95 fetuses (52 female neonates, 43 male neonates) with CDH between 22 and 39 weeks gestation by using multiplanar T2-weighted half-Fourier acquired single-shot turbo spin-echo MR imaging. On the basis of logistic regression analysis results, mortality and the need for ECMO therapy were calculated for fetuses before and after 30 weeks gestation. RESULTS Overall, higher FLV was associated with improved survival (P < .001) and decreasing probability of need for ECMO therapy (P = .008). Survival at discharge was 29.2% in neonates with an FLV of 5 mL, compared with 99.7% in neonates with an FLV of 25 mL. The corresponding need for ECMO therapy was 56.1% in fetuses with an FLV of 5 mL and 8.7% in fetuses with an FLV of 40 mL. Prognostic power was considerably lower before 30 weeks gestation. CONCLUSION Beyond 30 weeks gestation, logistic regression analysis that is based on MR FLV measurements is useful to estimate neonatal survival rates and ECMO requirements. Prior to 30 weeks gestation, the method is not reliable and the FLV measurement should be repeated, particularly in fetuses with small lung volumes, before a decision is made about therapeutic options.

Abstract
The Congenital Diaphragmatic Hernia Registry (CDHR) was established to collect data on all infants treated at participating institutions with congenital diaphragmatic hernia (CDH) to assess therapy and improve outcome. Since 1995, the CDHR has accumulated data on over 4000 infants. The collective efforts of the CDH Study Group have provided valuable information regarding the efficacy of various therapeutic interventions and have tried to establish predictors of outcome. Because CDH is an uncommon, heterogeneous structural anomaly with a wide spectrum of severity, individual institutions may vary significantly in their experiences and treatment approaches. International multicenter registries, like the CDHR, are useful to provide clinically relevant direction by accumulating far more data on a large patient population than any single institution might.

Abstract
The purpose of this historical study was to compare the outcome for two treatment strategies, for neonates with congenital diaphragmatic hernia (CDH). The records of 65 infants born between 1991 and 2005 with CDH from a single tertiary care perinatal centre in the United Kingdom were retrospectively reviewed. Conventional mechanical ventilation (CMV) and systemic vasodilators were used from 1991 to 1995 (era 1). High frequency oscillatory ventilation (HFOV) and nitric oxide (NO) were used between 1996 and 2005 (era 2). Main outcome measures were survival and incidence of chronic lung disease. The results showed that the survival rate was 38% (8/21) in era 1 and 73% (32/44) in era 2, 95% CI for difference -59 to -10%. The incidence of chronic lung disease in survivors was 45% (5/11) in era 1 and 30% (9/30) in era 2, 95% CI for difference -18 to 49%. These data show significantly improved survival with elective use of HFOV and NO compared to CMV and systemic vasodilators. The survival results for CDH at St George's Hospital are comparable to those published from other institutions. The results may reflect a reduction in ventilator-induced lung injury with HFOV compared to CMV.

Abstract
Conventional treatment of respiratory failure involves positive pressure ventilation with high concentrations of inspired oxygen. If adequate gas exchange still cannot be achieved extracorporeal membrane oxygenation (ECMO) may be an option. The general indication for ECMO for respiratory insufficiency is a reversible pulmonary disease, which cannot be managed by conventional means. ECMO is a modified heart-lung machine. Blood is withdrawn from a central vein in the patient and pumped through an artificial oxygenator back to the patient, either to a central artery (veno-arterial ECMO) or to a central vein (veno-venous ECMO). Total gas exchange can be achieved through the extracorporeal system, and the lungs do not have to be subjected to high-pressure ventilation. To date over 21,500 neonates have been treated with ECMO with an overall survival to hospital discharge of 76%. Meconium aspiration syndrome carries the highest survival (94%), whereas congenital diaphragmatic hernia on ECMO only has a survival of 52%. A total of 3500 pediatric patients (30 days to 18 years) have been treated with ECMO with a survival of 56%. Aspiration and viral pneumonia are the pediatric diagnoses with the highest survival rates. Randomized controlled studies have shown a significant advantage of ECMO with regard to survival in neonates. In the pediatric age group, nonrandomized studies have shown lower mortality in ECMO-treated patients.

Abstract
The incidence of congenital diaphragmatic hernia (CDH) may be as high as 1 in 2000. Over the past two decades, antenatal diagnosis rates have increased, the pathophysiology of CDH has become better understood, and advances in clinical care, including foetal surgery, have occurred. However, there remains a paucity of randomised controlled trials to provide evidence-based management guidelines. Reports of improved survival rates appear to be confined to a select subset of CDH infants, surviving to surgical repair, while the overall mortality, at over 60%, appears to be unchanged, largely due to the often forgotten 'hidden mortality' of CDH. The significant long-term morbidity in surviving infants has become apparent, and the need for long-term multidisciplinary follow up established. A total of 10% of cases may present later in life, and misdiagnosis on initial chest X-ray may lead to significant morbidity.

Abstract
OBJECTIVE The purpose of our study was to prospectively assess, using MRI and MR angiography, the cerebral and vascular status of 2-year-old children with congenital diaphragmatic hernia (CDH) in whom carotid artery reconstruction was performed after neonatal extra-corporeal membrane oxygenation (ECMO) therapy and to compare the neurologic development of children with vascular reocclusion with that of CDH children with successful repair and with non-ECMO controls. SUBJECTS AND METHODS A total of 30 infants (17 boys, 13 girls; 2 +/- 0.26 years) were included. Of these, 18 (60%) infants received arteriovenous ECMO therapy with subsequent reconstruction of the right common carotid artery (RCCA). Two years postoperatively, the children were examined with cerebral MRI, including 3D time-of-flight and contrast-enhanced 3D MR angiography of the intra- and extracranial brain-supplying arteries. The pathologic findings were analyzed for the ability to predict impaired neurologic development. RESULTS The RCCA was occluded or highly stenotic in 13 (72%) of 18 children. All infants showed intra- and extracranial collaterals and a patent internal carotid artery. The average duration of ECMO was not longer than in cases of successful reconstruction (p = 1). The ECMO group showed a significantly greater incidence of cerebral injuries (p = 0.007) but no relevant impairment in neurologic development compared with controls (p = 0.26). Unsuccessful RCCA repair had no predictive value for a poor neurologic outcome (p = 1). CONCLUSION The outcome of RCCA repair after ECMO is possibly poorer than expected, with vascular occlusion or high-grade stenosis occurring in almost three quarters of patients. Although reocclusion of the RCCA does not increase the risk for cerebral lesions or an impaired neurologic development during the first 2 years postoperatively, the overall benefit of RCCA repair remains doubtful, and the potential long-term risk arising from these plaques has yet to be assessed.
