A clinical consensus guideline for nutrition in infants with congenital diaphragmatic hernia from birth through discharge. J Perinatol 2024; 44:694-701. [PMID: 38627594 DOI: 10.1038/s41372-024-01965-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/30/2023] [Revised: 03/28/2024] [Accepted: 04/08/2024] [Indexed: 05/15/2024]
Abstract
OBJECTIVE To develop a consensus guideline to meet nutritional challenges faced by infants with congenital diaphragmatic hernia (CDH). STUDY DESIGN The CDH Focus Group utilized a modified Delphi method to develop these clinical consensus guidelines (CCG). Topic leaders drafted recommendations after literature review and group discussion. Each recommendation was sent to focus group members via a REDCap survey tool, and members scored on a Likert scale of 0-100. A score of > 85 with no more than 25% outliers was designated a priori as demonstrating consensus among the group. RESULTS In the first survey 24/25 recommendations received a median score > 90 and after discussion and second round of surveys all 25 recommendations received a median score of 100. CONCLUSIONS We present a consensus evidence-based framework for managing parenteral and enteral nutrition, somatic growth, gastroesophageal reflux disease, chylothorax, and long-term follow-up of infants with CDH.

Abstract
Infants born with congenital diaphragmatic hernia have high mortality and morbidity and require coordinated multidisciplinary care for optimal outcomes. Over the past several decades numerous articles have been published on the technical aspects of the care of these patients demonstrating both the variation in management across institutions as well as the desirability and need for standardization of care. Unfortunately, none have focused on the organization of care for CDH patients encompassing the range from early prenatal diagnosis to long-term postnatal care. However, to achieve optimal care and optimal outcomes, it is important to not only have excellent technical surgical and medical care but also to have an organized, systematic, and purposefully designed program for the delivery of healthcare to infants with this condition. In this article, based on our experience and drawing on general principles of building clinical programs, we describe the important elements of an ideal CDH program.

Abstract
BACKGROUND This study aimed to evaluate the effectiveness of video-assisted thoracic surgery for the treatment of congenital diaphragmatic hernia (CDH) in a larger series compared with conventional open surgery. Additionally, we summarized the experience of thoracoscopic surgery in the treatment of CDH in infants. METHODS We retrospectively analysed the clinical data of 109 children with CDH who underwent surgical treatment at the Department of Cardiothoracic Surgery of Children's Hospital of Chongqing Medical University from January 2011 to January 2021. According to the surgical method, the children were divided into an open group (62 cases) and a thoracoscopy group (47 cases).Patients who underwent surgical correction had the diaphragmatic defect size graded (A-D) using a standardized system. We compared the operation time, intraoperative blood loss, postoperative mechanical ventilation time, postoperative hospital stay, postoperative CCU admission time and other surgical indicators as well as the recurrence rate, mortality rate and complication rate of the two groups of children. RESULTS The index data on the operation time, intraoperative blood loss, postoperative mechanical ventilation time, postoperative hospital stay and postoperative CCU admission time were better in the thoracoscopy group than in the open group. The difference between the two groups was statistically significant (P < 0.05). We compared the number of incision infections, lung infections, atelectasis, pleural effusion, and chylothorax between the two groups. There were more children in the open group than in the thoracoscopy group. The overall incidence of postoperative complications in the open group (51.61%) was higher than that in the thoracoscopy group (44.68%).The recurrence rate of the thoracoscopy group (8.51%) was higher than that of the open group (3.23%). In the open group, 7 patients died of respiratory distress after surgery, and no patients died in the thoracoscopy group. CONCLUSIONS Thoracoscopic surgery and open surgery can effectively treat CDH. Compared with conventional open surgery, thoracoscopy has the advantages of shorter operation time, less trauma, faster recovery and fewer complications. We believe that thoracoscopic surgery for type A/B diaphragmatic defect has certain advantages, but there is a risk of recurrence.

Abstract
Purpose: To describe a minimally invasive technique with primary closure and strong suture connection that is feasible in cases of larger, most common type B defects of congenital diaphragmatic hernia (CDH). Background: The thoracoscopic approach (TA) is a favorable technique for the repair of CDH and is still evolving globally. A common issue is finding the optimal suture technique for secure closure in order to prevent recurrences. Whether a defect can be closed only by sutures or by using a patch depends on the size of CDH, the presence of a muscular rim along the inner thoracic surface and finally on the surgeon’s experience. From a geometrical point of view, the challenge is to transform the circular defect into a line, without tension, with a strong compound and preferably without additional material. To address this, we apply a setting of the sutures in a “T-shape” and a way to lead the sutures around the rib bones in order to increase stability. This method allows for the primary closure of CDHs and also applies to larger defects. Cases: We present seven newborns with posterolateral CDH on the left side. The defects were solely repaired by TA and by the suturing technique described in detail.

Abstract
Congenital diaphragmatic hernia (CDH) is a rare birth defect characterized by incomplete closure of the diaphragm and herniation of fetal abdominal organs into the chest that results in pulmonary hypoplasia, postnatal pulmonary hypertension owing to vascular remodelling and cardiac dysfunction. The high mortality and morbidity rates associated with CDH are directly related to the severity of cardiopulmonary pathophysiology. Although the aetiology remains unknown, CDH has a polygenic origin in approximately one-third of cases. CDH is typically diagnosed with antenatal ultrasonography, which also aids in risk stratification, alongside fetal MRI and echocardiography. At specialized centres, prenatal management includes fetal endoscopic tracheal occlusion, which is a surgical intervention aimed at promoting lung growth in utero. Postnatal management focuses on cardiopulmonary stabilization and, in severe cases, can involve extracorporeal life support. Clinical practice guidelines continue to evolve owing to the rapidly changing landscape of therapeutic options, which include pulmonary hypertension management, ventilation strategies and surgical approaches. Survivors often have long-term, multisystem morbidities, including pulmonary dysfunction, gastroesophageal reflux, musculoskeletal deformities and neurodevelopmental impairment. Emerging research focuses on small RNA species as biomarkers of severity and regenerative medicine approaches to improve fetal lung development.

Abstract
OBJECTIVE Antenatal recognition of severe cases of congenital diaphragmatic hernia (CDH) by ultrasound (US) and magnetic resonance imaging (MRI) may aid decisions regarding the indication of fetal endoscopic tracheal occlusion. METHODS An integrative review was performed. Searches in MEDLINE and EMBASE used terms related to CDH, diagnosis, MRI, and US. The inclusion criteria were reviews and guidelines approaching US and MRI markers of severity of CDH published in English in the past 10 years. RESULTS The search retrieved 712 studies, out of which 17 publications were included. The US parameters were stomach and liver positions, lung-to-head ratio (LHR), observed/expected LHR (o/e LHR), and quantitative lung index. The MRI parameters were total fetal lung volume (TFLV), observed/expected TFLV, relative fetal or percent predicted lung volumes, liver intrathoracic ratio, and modified McGoon index. None of the parameters was reported to be superior to the others. CONCLUSION The most mentioned parameters were o/e LHR, LHR, liver position, o/e TFLV, and TFLV.

Abstract
Congenital diaphragmatic hernia (CDH) is a rare congenital anomaly, whose presentation is complicated by pulmonary hypertension (PH), pulmonary hypoplasia, and myocardial dysfunction, each of which have significant impact on short-term clinical management and long-term outcomes. Despite many advances in therapy and surgical technique, optimal CDH management remains a topic of debate, due to the variable presentation, complex pathophysiology, and continued impact on morbidity and mortality. One of the more recent management strategies is the use of prostaglandin E1 (PGE1) infusion in the management of PH associated with CDH. PGE1 is widely used in the NICU in critical congenital cardiac disease to maintain ductal patency and facilitate pulmonary and systemic blood flow. In a related paradigm, PGE1 infusion has been used in situations of supra-systemic right ventricular pressures, including CDH, with the therapeutic intent to maintain ductal patency as a "pressure relief valve" to reduce the effective afterload on the right ventricle (RV), optimize cardiac function and support pulmonary and systemic blood flow. This paper reviews the current evidence for use of PGE1 in the CDH population and the opportunities for future investigations.

Abstract
The consequences of most hernias can be immediately corrected by surgical repair. However, this isn't always the case for children born with a congenital diaphragmatic hernia. The derangements in physiology encountered immediately after birth result from pulmonary hypoplasia and hypertension caused by herniation of abdominal contents into the chest early in lung development. This degree of physiologic compromise can vary from mild to severe. Postnatal management of these children remains controversial. Although heavily studied, multi-institutional randomized controlled trials are lacking to help determine what constitutes best practice. Additionally, the results of the many studies currently within the literature that have investigated differing aspect of care (i.e., inhaled nitric oxide, ventilator type, timing of repair, role of extracorporeal membrane oxygenation, etc.) are difficult to interpret due to the small numbers investigated, the varying degree of physiologic compromise, and the contrasting care that exists between institutions. The aim of this paper is to review areas of controversy in the care of these complex kids, mainly: the use of fraction of inspired oxygen, surfactant therapy, gentle ventilation, mode of ventilation, medical management of pulmonary hypertension (inhaled nitric oxide, sildenafil, milrinone, bosentan, prostaglandins), the utilization of extracorporeal membrane oxygenation, and the timing of surgical repair.

Abstract
PURPOSE Given that the application of thoracoscopic surgery to late-presenting congenital diaphragmatic hernia (CDH) in infants and children is controversial, we summarized our experiences with patients at two medical centers and aimed to discuss the safety and feasibility of thoracoscopic repair. MATERIALS AND METHODS A retrospective review of late-presenting CDH cases involving patients who underwent thoracoscopic repair from October 2010 to June 2017 was performed. Data, including patients' demographic characteristics, manipulative details, and postoperative complications, were extracted and analyzed. RESULTS A total of 59 cases were included in this study. Patients ranged in age from 2 months to 8 years (mean: 18 months). Twenty-five patients presented with shortness of breath and dyspnea. Furthermore, 34 cases were found occasionally. Forty-six left-sided hernias and 13 right-sided hernias were found. Operating time ranged from 30 to 100 minutes (mean: 55 minutes), and the amount of blood loss was 3-5 mL (mean: 3.8 mL). The size of the diaphragmatic defect ranged from 2 × 2 cm to 5 × 8 cm. The chest tubes were taken out within 24 hours. The average length of postoperative hospital stay was 5.2 ± 0.4 days (range: 4-6 days). The length of the follow-up period ranged from 3 months to 3 years (mean: 18 months), with no recurrences. CONCLUSION Thoracoscopic repair of late-presenting CDH is a safe and efficacious technique. It can facilitate the procedure and decrease the recurrence rate by shifting the focus to operative details. The prognosis is excellent once the correct operative details are achieved.

Abstract
BACKGROUND Erythropoietin (EPO), an essential stimulator of erythropoiesis produced by the fetal liver, is important both in vascular remodeling and modulation of the endothelial response in the pulmonary vasculature. In addition, EPO guides alveolar development, along with retinoic acid (RA). EPO is a direct target of RA, and the retinoid pathway is altered in the nitrofen-induced congenital diaphragmatic hernia (CDH) model. In the present study, we tested the hypothesis that the synthesis of EPO is suppressed in a rat model of CDH. MATERIALS AND METHODS Pregnant rats were treated with either nitrofen or vehicle on gestational day 9 (D9). Fetuses were sacrificed on D19 and D21 and divided into control and CDH groups. Immunohistochemistry and quantitative real-time polymerase chain reaction (RT-PCR) were performed to determine the expression of EPO in the fetal liver and kidney. We also estimated the expression of EPO receptor in the fetal lung. RESULTS The relative EPO mRNA expression in the liver on D19 and in the kidney on D21 were significantly lower in the CDH group than in the controls (P = 0.0008 and P = 0.0064, respectively). In addition, the results of immunohistochemistry supported the findings from the RT-PCR analysis. No significant changes were noted in the expression pattern or EPO receptor levels in the fetal lungs of the CDH group compared to the controls. CONCLUSIONS Our results reveal the suppressed EPO synthesis in the CDH fetus, which may contribute to the pathogenesis of lung hypoplasia and modification of pulmonary vasculature in the CDH rat model.

Abstract
OBJECTIVE To compare endotracheal fluid (EF) and amniotic fluid (AF) phospholipidic profile changes following tracheal occlusion (TO) in the congenital diaphragmatic hernia (CDH) fetal lamb model, in order to support the efficacy of TO on lung maturity. METHODS A diaphragmatic defect was induced at 70 days' gestation, TO was carried out at day 102 and cesarean section at 136 days' gestation. EF and AF samples, collected at delivery, were evaluated using mass spectrometry (the analysis focused on palmitoyloleoyl-phosphatidylcholine [POPC, PC(18:1/16:0)], dipalmitoyl-phosphatidylcholine [DPPC, PC(16:0/16:0)] and sphingomyelins [SMs]). RESULTS The effects of CDH and TO were different on AF and EF. POPC levels were higher than DPPC levels in AF of healthy lambs. Following induction of the diaphragmatic malformation, an evident decrease in POPC was noted, while a substantial return to normal POPC levels and an increased DPPC peak were prompted by the TO. After CDH induction, a decrease in N-palmitoyl-D-sphingomyelin [SM(d18:1/16:0)] was revealed (P<0.01) and an increased peak in SMs in AF was prompted by the TO (P=0.05). While the most represented phosphatidylcholine (PC) species in EF of healthy lambs was DPPC, CDH induced a decrease in the DPPC peak and treatment with TO induced its partial recovery. SMs were detectable only in healthy EF samples. CONCLUSION The phospholipid recovery profile following TO suggests the potential role of this therapy in restoring processes involved in surfactant-mediated lung maturation, even though other interactions involved in AF turnover should be considered. Moreover, these metabolites could be used as biomarkers of fetal pulmonary development.

Morgan TA, Basta A, Filly RA. Fetal stomach and gallbladder in contact with the bladder wall is a common ultrasound sign of stomach-down left congenital diaphragmatic hernia. JOURNAL OF CLINICAL ULTRASOUND : JCU 2017; 45:8-13. [PMID: 27663268 DOI: 10.1002/jcu.22400] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/14/2016] [Accepted: 08/21/2016] [Indexed: 06/06/2023]
Abstract
PURPOSE The aim of this study was to identify sonographic (US) findings that can assist in prenatal diagnosis of stomach-down left congenital diaphragmatic hernia (CDH), specifically related to positioning of the abdominal contents including the stomach, bladder, and gallbladder. METHODS All US examinations with a postnatally confirmed diagnosis of stomach-down left CDH over a 13-year period were retrospectively reviewed for abnormal position of the abdominal contents, including whether the fetal stomach was in contact with the urinary bladder. Normal fetuses that underwent comprehensive US surveys were similarly evaluated for comparison in a 2:1 ratio. RESULTS Twenty-two fetuses with stomach-down left CDH were identified in a cohort of 278 fetuses with left CDH. In 15/22 (68.2%) cases of stomach-down left CDH, the bladder and stomach walls were in contact. Contact of the fetal gallbladder with the fetal bladder wall was also observed and was present even more commonly (17/22 cases [77.3%]). There was no case of either the stomach or gallbladder in contact with the bladder wall in the normal fetal cohort (n = 44). CONCLUSIONS Recognition of the fetal stomach and/or gallbladder in contact with the bladder wall can help in the detection of stomach-down left CDH. © 2016 Wiley Periodicals, Inc.

Pediatr Surg Int 2016; 32:1121-1126.

Abstract
PURPOSE High mortality and morbidity in infants born with congenital diaphragmatic hernia (CDH) are attributed to pulmonary hypoplasia and pulmonary hypertension (PH). Forkhead box (Fox) transcription factors are known to be crucial for cell proliferation and homeostasis. FoxF1 is essential for lung morphogenesis, vascular development, and endothelial proliferation. Mutations in FoxF1 and also the Fox family member FoxC2 have been identified in neonates with PH. In human and experimental models of arterial PH, the Fox protein FoxO1 was found to be downregulated. We hypothesized that Fox expression is altered in the lungs of the nitrofen-induced CDH rat model and investigated the expression of FoxF1, FoxC2, and FoxO1. METHODS Following ethical approval (Rec 913b), time-pregnant Sprague-Dawley rats received nitrofen or vehicle on gestational day (D9). Fetuses were sacrificed on D21, inspected for CDH and divided into CDH (n = 11) and control group (n = 11). Gene expression of FoxF1, FoxC2, and FoxO1 was evaluated with qRT-PCR. Detected alterations of mRNA levels were subsequently assessed on the protein level by performing western blot analysis and laser scanning confocal microscopy. RESULTS The relative mRNA level of FoxF1 was significantly downregulated in CDH lungs compared to controls (FoxF1 CDH 1.047 ± 0.108, FoxF1 Ctrl 1.419 ± 0.01, p = 0.014). Relative mRNA levels of FoxC2 and FoxO1 were not found to be altered between the experimental groups (FoxC2 CDH 30.74 ± 8.925, FoxC2 Ctrl 27.408 ± 7.487, p = 0.776; FoxO1 CDH 0.011 ± 0.002, FoxO1 Ctrl 0.011 ± 0.001, p = 0.809). On the protein level, western blotting demonstrated a reduced pulmonary protein expression of FoxF1 in CDH lungs. Confocal microscopy showed a markedly diminished expression of FoxF1 in the pulmonary vasculature of CDH lungs compared to controls. CONCLUSION Our study demonstrates a strikingly reduced expression of FoxF1 in the pulmonary vasculature of nitrofen-induced CDH. Altered FoxF1 gene expression during embryogenesis may participate in vascular maldevelopment resulting in PH in this animal model.
