Abstract
Congenital diaphragmatic hernia (CDH) is a rare developmental defect of the diaphragm, characterized by the herniation of abdominal contents into the chest, resulting in varying degrees of pulmonary hypoplasia and pulmonary hypertension. Significant advances in the prenatal diagnosis and identification of prognostic factors have resulted in the continued refinement of the approach to fetal therapies for CDH. In the postnatal period, protocolized approaches to lung-protective ventilation, nutrition, prevention of infection, and early aggressive management of pulmonary hypertension have led to improved outcomes in infants with CDH. Surgical repair of CDH is not urgent in most circumstances and can be delayed until the pulmonary status of the patient has stabilized. This article provides a comprehensive review of CDH, focusing on the complex pathophysiology, advances in prenatal diagnosis, fetal interventions, and optimal postnatal management of CDH.

The Genomics of Congenital Diaphragmatic Hernia: A 10-Year Retrospective Review. J Pediatr 2022; 248:108-113.e2. [PMID: 35430246 DOI: 10.1016/j.jpeds.2022.04.012] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/08/2021] [Revised: 03/26/2022] [Accepted: 04/08/2022] [Indexed: 12/13/2022]
Abstract
OBJECTIVE To evaluate genetic testing use in infants with congenital diaphragmatic hernia (CDH) over the past decade to better inform future practices and individualize prognostication and management. STUDY DESIGN A retrospective cohort study was performed of all infants with CDH enrolled in the Pulmonary Hypoplasia Program at Children's Hospital of Philadelphia, born between January 2011 and February 2021. For each infant, demographic information, prenatal and postnatal history, and genetic testing were reviewed. RESULTS The charts of 411 infants were analyzed. Overall, 22% (n = 89) were complex/syndromic and 78% (n = 322) were isolated/nonsyndromic. Mortality was significantly higher in complex/syndromic infants (P < .001) and in infants with diagnostic genetic testing (P < .001). Microarray was diagnostic in 9% (n = 34/399) and exome sequencing was diagnostic in 38% (n = 15/39). Genetic testing was diagnostic in 57% (n = 51/89) of complex/syndromic infants, but in only 2% of isolated/nonsyndromic infants (n = 8/322). Overall, genetic testing was diagnostic in 14% (n = 56). CONCLUSIONS The high diagnostic rate in this cohort highlights the utility of comprehensive genetic testing in infants with CDH. However, 43% of complex/syndromic and 98% of isolated/nonsyndromic infants do not have a genetic etiology identified. This finding underscores the need for additional genetic and genomic studies (eg, whole genome, RNA sequencing) to identify novel genes and mutational mechanisms (single genes, regulatory elements, complex traits) that will allow for improved diagnostic rates and ultimately individualized management of infants with CDH.

Abstract
Introduction Morgagni Hernia (MH) is a type of congenital diaphragmatic hernia (CDH). CDH is a diaphragmatic discontinuity that permits abdominal viscera to herniate into the chest during development. It does not only occur in early childhood but also has been reported in adults. The most prevalent clinical sign of MH is respiratory disorder of all ages. Case presentation An elderly woman with a known history of diabetes, ischemic heart disease, hypertension, and constipation presented to us with increased abdominal pain. Besides, her PCR test results were positive for COVID-19. She underwent diagnostic laparoscopy surgery. The incision was closed with an intracorporeal suture, and then dual mesh was fixed to diaphragmatic wall. The postoperative progress was satisfactory two weeks after surgery. Based on a negative PCR test, the patient was discharged from the hospital. Discussion The foramina of Morgagni is a defect in the costosternal trigons produced by a lack of anterior pleuroperitoneal membrane muscularization. Although gastrointestinal symptoms and cardiorespiratory discomfort are typically connected with the diagnosis and treatment of MH in youngsters, there are a few middle-aged people who, like our case, develop symptoms suddenly. Albeit a paradigm change in the 21st century deems less invasive laparoscopic surgery to be the treatment of choice, open surgical procedures via a trans-thoracic or trans-abdominal route are still used. Conclusion MH is indeed uncommon in adults, but in patients with an acute onset of intestinal obstruction, the possibility of MH should be in mind. It can be fatal if it is misdiagnosed. The possibility of Morgagni hernia should be in mind even in elderly patients Laparoscopic technique is one of the best approaches to the Morgagni hernia cause all abdominal organs can be evaluated with laparoscopy in a minimally invasive manner. The operation can be performed in a COVID-19 positive patient. COVID-19 may be a spark of underlying disease manifestations.

Abstract
OBJECTIVE A congenital diaphragmatic hernia (CDH) complicated with gastric perforation is extremely rare. Herein, we report an unusual case of unexpected intrauterine gastric perforation of a left side CDH with concurrent pleural effusion and ascites. CASE REPORT A 21-year-old female underwent prenatal ultrasound at 37 weeks of gestation and revealed a left side CDH, pleural effusion with a large thick-walled cystic mass over the left thorax, ascites, and polyhydramnios. Under the impression of CDH with suspected gastric perforation, Cesarean delivery was arranged and a male neonate was delivered. The neonate received emergency laparotomy soon and a herniation originated from the foramen of Bochdalek and a perforation located in the stomach body along the greater curvature were found. The pathologic diagnosis was consistent with a spontaneous gastric perforation with ischemic change. CONCLUSION Sonographic findings of pleural effusion and ascites associated with CDH are clues of antenatal gastrointestinal perforation.

Abstract
Congenital diaphragmatic hernia (CDH) is a developmental birth defect consisting of a diaphragmatic defect and abnormal lung development. CDH complicates 2.3-2.8 per 10,000 live births. Despite efforts to standardize clinical practice, management of CDH remains challenging. Frequent re-evaluation of clinical practices in CDH reveals that management of CDH is evolving from one of postnatal stabilization to prenatal optimization. Translational research reveals promising avenues for in utero therapeutic intervention, including fetoscopic endoluminal tracheal occlusion. These remain highly experimental and demand improved antenatal diagnostics. Timely diagnosis of CDH and identification of severely affected fetuses allow time for delivery planning or in utero therapeutics. Optimal perinatal care and surgical treatment strategies are highly debated. Improved CDH mortality rates have placed increased emphasis on identifying and monitoring the long-term sequelae of disease throughout childhood and into adulthood. We review the current management strategies for CDH, highlighting where progress has been made, and where future developments have the potential to revolutionize care in this vulnerable patient population.

Abstract
Bilateral agenesis of the diaphragm is a very rare congenital diaphragmatic defect. Bilateral congenital diaphragmatic hernia (CDH) is much more frequently associated with other anomalies compared with unilateral CDH (70% vs 30%-40%). These include cardiovascular, respiratory (other than lung hypoplasia), gastrointestinal, renal, and genital malformations. We report a case of complete bilateral agenesis of the diaphragm associated with a horseshoe kidney and an imperforate anus. These additional malformations have not previously been reported in association with complete bilateral agenesis of the diaphragm. We also present a review of previous cases of total diaphragm agenesis published in the English language and provide some insights about pathogenesis.

Abstract
The importance of the complete absence of a hemidiaphragm or unilateral diaphragmatic agenesis in adulthood in relation to performing laparoscopic procedures has not been well documented. This article reports for the first time in literature a case of successful laparoscopic cholecystectomy in an adult with previously undiagnosed unilateral diaphragmatic agenesis. A 36-year-old female complaining of stubborn right upper abdominal pain radiating to her upper back was diagnosed as having cholelithiasis and was scheduled for laparoscopic cholecystectomy. There were also bilateral upper extremity malformations to a certain level. Routine diagnostic tests demonstrated that her entire liver and some bowel loops were in the right hemithorax, suggesting right-sided diaphragmatic hernia. Laparoscopic procedure was performed with the insertion of four trocars. Exploration of abdomen revealed total absence of the right hemidiaphragm. Cholecystectomy was completed laparoscopically in about 45 minutes without need for additional trocars. Patient had an uneventful recovery and was discharged on the second postoperative day without any complaint. Laparoscopic cholecystectomy in adults with diaphragmatic agenesis and intrathoracic abdominal viscera can be performed successfully. Nevertheless, any bile duct aberrations must be documented prior to surgery, and the surgeon should be able to convert to open procedure if necessary.

Abstract
Acute respiratory failure requiring assisted ventilation is one of the most common reasons for admission to the neonatal intensive care unit. Respiratory failure is the inability to maintain either normal delivery of oxygen to the tissues or normal removal of carbon dioxide from the tissues. It occurs when there is an imbalance between the respiratory workload and ventilatory strength and endurance. Definitions are somewhat arbitrary but suggested laboratory criteria for respiratory failure include two or more of the following: PaCO2 > 60 mmHg, PaO2 < 50 mmHg or O2 saturation <80 % with an FiO2 of 1.0 and pH < 7.25 (Wen et al. 2004).

Abstract
Congenital Diaphragmatic Hernia (CDH) is defined by the presence of an orifice in the diaphragm, more often left and posterolateral that permits the herniation of abdominal contents into the thorax. The lungs are hypoplastic and have abnormal vessels that cause respiratory insufficiency and persistent pulmonary hypertension with high mortality. About one third of cases have cardiovascular malformations and lesser proportions have skeletal, neural, genitourinary, gastrointestinal or other defects. CDH can be a component of Pallister-Killian, Fryns, Ghersoni-Baruch, WAGR, Denys-Drash, Brachman-De Lange, Donnai-Barrow or Wolf-Hirschhorn syndromes. Some chromosomal anomalies involve CDH as well. The incidence is < 5 in 10,000 live-births. The etiology is unknown although clinical, genetic and experimental evidence points to disturbances in the retinoid-signaling pathway during organogenesis. Antenatal diagnosis is often made and this allows prenatal management (open correction of the hernia in the past and reversible fetoscopic tracheal obstruction nowadays) that may be indicated in cases with severe lung hypoplasia and grim prognosis. Treatment after birth requires all the refinements of critical care including extracorporeal membrane oxygenation prior to surgical correction. The best hospital series report 80% survival but it remains around 50% in population-based studies. Chronic respiratory tract disease, neurodevelopmental problems, neurosensorial hearing loss and gastroesophageal reflux are common problems in survivors. Much more research on several aspects of this severe condition is warranted.

Abstract
BACKGROUND/PURPOSE The prognosis for multiple vs singleton pregnancies affected by congenital diaphragmatic hernia (CDH) is not known. To improve the counseling of families with multiple gestation pregnancies complicated by CDH, we examined outcomes of a consecutive series of CDH cases occurring in multiple gestation pregnancy referrals. METHODS Clinical characteristics and morbidity and mortality data were gathered for a consecutive series of infants with CDH from 16 multiple gestation pregnancies. Outcomes were compared to a cohort of 91 patients with CDH from singleton pregnancies. Multivariate regression was also used in an attempt to determine whether multiple gestation pregnancy was independently predictive of subsequent long-term adverse outcomes. RESULTS Four pregnancies were lost to follow-up, and 1 underwent selective reduction. Overall mortality for live-born multiple gestation fetuses affected by CDH was 30% and was 8% for unaffected siblings. No pregnancy was concordant. Clinical features were not different between the case series and control infants, except median gestational age at delivery, which was significantly lower for the multigestational infants (34 [range, 32-36] vs 38 [range, 28-41] weeks) (P = .02). Long-term morbidity was comparable between cases and controls. CONCLUSIONS In terms of mortality, outcomes of multigestational pregnancies affected by CDH are no worse than for CDH pregnancies in general. Long-term risk may depend more on CDH severity rather than the presence of multiple fetuses.

Abstract
Congenital absence of the left pericardium (allowing communication between pericardial and pleural cavities) is a rare developmental defect that results from faulty partitioning of the pleuropericardic cavity during the 5th week of development. It occurs sporadically in most instances, and may be associated with other malformations of the thoracic viscera. We report here two sibs born to consanguineous parents with absent left fibrous pericardium and developmental defects of the septum transversum: left posterolateral diaphragmatic hernia in one child, left diaphragmatic eventration in the other sib. This appears to be the first familial report of this rare association.

Abstract
The management of congenital diaphragmatic hernia (CDH) in the newborn infant has changed radically since the first successful outcomes were reported 60 years ago. Then it seemed a surgical problem with a surgical solution – do an operation, remove the intestines and solid viscera from the thoracic cavity, repair the defect and allow the lung to expand. CDH in that era was regarded as the quintessential neonatal surgical emergency. The expectation was that urgent surgery would result in improvement in lung function and oxygenation. That approach persisted up to the 1980s when it was realized that the problem was far more complex and involved both an abnormal pulmonary vascular bed as well as pulmonary hypoplasia. The use of systemically delivered pulmonary vasodilator therapy, principally tolazoline, became a focus of interest in the 1980s with small case reports and case series suggesting improved survival. In the 1990s, based on studies that showed worsening thoracic compliance and gas exchange following surgical repair, deferred surgery and pre-operative stabilization became the standard of care. At the same time extracorporeal membrane oxygenation (ECMO) was increasingly used either as part of pre-operative stabilization or as a rescue therapy after repair. Other centres chose to use high frequency oscillatory ventilation (HFOV). Despite all these innovations the survival in live born infants with CDH did not improve to more than 50% in large series published from high volume centres. However, in the past 10 years there has been an appreciable improvement in survival to the extent that many centres are now reporting survival rates of greater than 80%. Probably the biggest impact on this improvement has been the recognition of the role that ventilation induced lung injury plays in mortality and the need for ECMO rescue. This has ushered in an era of a lung protective or “gentle ventilation” strategy which has been widely adopted as a standard approach. While there have been these radical changes in postnatal management attempts have been made to improve outcome with prenatal interventions, starting with prenatal repair, which was abandoned because of preterm labour. More recently there has been increasing experience in the use of balloon occlusion of the trachea as a prenatal intervention strategy with patients being selected based on prenatal predictors of poor outcome. This approach can only be justified if those predictors can be validated and the outcomes (death or serious long term morbidity) can be shown to be better than those currently achievable, namely 80% survival in high volume CDH centres rather than the 50–60% survival frequently quoted in historical papers.

Abstract
Congenital diaphragmatic hernia (CDH) is a common and well-studied birth defect. The etiology of most cases remains unknown but increasing evidence points to genetic causation. The data supporting genetic etiologies which are detailed below include the association of CDH with recurring chromosome abnormalities, the existence of CDH-multiplex families, and the co-occurrence of CDH with additional congenital malformations.

Abstract
Congenital diaphragmatic hernia (CDH) is a common and often devastating birth defect. In order to learn more about possible genetic causes, we reviewed and classified 203 cases of the Bochdalek hernia type identified through the Brigham and Women's Hospital (BWH) Active Malformation Surveillance Program over a 28-year period. Phenotypically, 55% of the cases had isolated CDH, and 45% had complex CDH defined as CDH in association with additional major malformations or as part of a syndrome. When classified according to likely etiology, 17% had a Recognized Genetic etiology for their CDH, while the remaining 83% had No Apparent Genetic etiology. Detailed analysis using this largest cohort of consecutively collected cases of CDH showed low precurrence among siblings. Additionally, there was no concordance for CDH among five monozygotic twin pairs. These findings, in conjunction with previous reports of de novo dominant mutations in patients with CDH, suggest that new mutations may be an important mechanism responsible for CDH. The twin data also raise the possibility that epigenetic abnormalities contribute to the development of CDH.

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
In a 10-year review of autopsy records from Lutheran General Hospital (1992-2002), 13 cases of congenital diaphragmatic hernia (CDH) were found. The fetuses ranged between 21 and 35 wk of gestation. Four were born alive and five were diagnosed prenatally. The defect was left-sided in 11 cases. Cytogenetic study revealed five cases with normal karyotype and three cases with complex karyotypes. In five cases, no karyotype was performed. The three complex karyotypes were: 46,XX,del(8)(p23.1), 47,XX, +i(12)(p10)[6]/46XX[14] (Pallister-Killian syndrome), and 47,XY,+der(22)t(11:22) (q23.3:q11.2). The unbalanced translocation of chromosomes 11 and 22 in congenital diaphragmatic hernia has not been previously described. Three fetuses had heart abnormalities, including one which was associated with the 8p deletion. The other two had no karyotype study. Neither in this study, nor in the literature, is there a consistent or prevailing association between a specific chromosomal anomaly and CDH. The embryologic closure of the diaphragmatic leaflets may be mediated by a nonstructural chromosomal defect, more than one gene, and/or may be related to abnormalities not currently detectable.

Abstract
After more than 2 decades of experimental and clinical work, fetal surgery is an accepted treatment option for highly selected fetuses with life-threatening anomalies. Fetal lung masses associated with hydrops are nearly 100% fatal. These lesions can be resected in utero if they are predominantly solid or multicystic. Thoracoamniotic shunt placement may be effective in the setting of a single large cyst. Fetuses diagnosed with left congenital diaphragmatic hernia before 26 weeks' gestation with associated liver herniation and a low right lung to head circumference ratio have a relatively poor prognosis with conventional therapy after birth, but in utero therapeutic approaches have yet to show a comparative survival benefit. A prospective randomized trial is required to critically evaluate the efficacy of fetal tracheal occlusion for severe diaphragmatic hernia. Fetal sacrococcygeal teratoma complicated with progressive high output cardiac failure may benefit from in utero resection of the tumor.

Abstract
After more than two decades of experimental and clinical work, fetal surgery has become an accepted treatment modality for selected fetuses with life-threatening anomalies. Color Doppler ultrasound and ultrafast fetal magnetic resonance imaging have enhanced the accuracy of prenatal evaluation traditionally made by ultrasound alone. Fetal lung masses associated with hydrops are nearly 100% fatal. These lesions can be resected in utero if they are predominantly solid or multicystic. Thoracoamniotic shunting may be effective in the setting of a single large predominant cyst. Fetuses diagnosed with left congenital diaphragmatic hernia before 26 weeks' gestation with liver herniation and a sonographic right lung to head circumference ratio (LHR) of less than one may benefit from fetal tracheal occlusion. Fetal sacrococcygeal teratoma complicated with placentomegaly, hydrops, or progressive high output heart failure may benefit from in utero resection of the tumor. Although preterm labor still remains the Achilles heel of open fetal surgery, effective tocolysis may, in the future, expand the scope of fetal surgery.

Abstract
Despite advances in postnatal care, patients born with a congenital diaphragmatic hernia (CDH) suffer substantial morbidity and mortality. The present study was undertaken to determine the prognostic influence of prenatally-diagnosed liver herniation in the hemithorax in fetuses with CDH. The medical records of 48 patients evaluated for a prenatally-diagnosed left CDH were retrospectively reviewed. Patients were analysed according to the position of the liver by prenatal ultrasound; 32 fetuses had a major portion of the liver herniated into the left hemithorax ('liver up') and 16 had an intra-abdominal liver ('liver down'). Liver position was determined using colour-flow Doppler ultrasonography. There were two fetal deaths in the liver-up group and one in the liver-down group. The liver-up group more frequently required extracorporeal membrane oxygenation (ECMO) support (53 per cent) compared with the liver-down group (19 per cent). Postnatal survival was significantly less in the liver-up group (43 per cent) vs. the liver-down group (93 per cent). Fetuses with congenital diaphragmatic hernia and liver herniated into the hemithorax have a much worse prognosis than similarly afflicted fetuses without liver herniation. Prenatal ultrasonographic diagnosis of congenital diaphragmatic hernia allows for preparation for a critically ill newborn and aids in prenatal family counselling.
