Difficult airway management and low Bispectral Index (BIS) in a patient with left Bochdalek congenital diaphragmatic hernia (CDH)

BackgroundBochdalek congenital diaphragmatic hernia (CDH) is a developmental defect in the posterolateral diaphragm, allowing herniation of abdominal contents into the thorax causing mechanical compression of the developing lung parenchyma and lung hypoplasia. We describe a case of an adult patient with a Bochdalek hernia who underwent minimally invasive right thoracotomy Perceval bioprosthetic aortic valve replacement (AVR) requiring one-lung ventilation (OLV) on the side of the hernia. This is a complex and challenging case that brings up numerous thought-provoking anesthetic implications. To the best of our knowledge, a Pubmed search did not reveal any publication to date of difficult airway management in an adult patient with CDH.Case presentationThe first major problem encountered was patient’s crus habitus anatomical condition (exceedingly ventrally displaced trachea) Mallampati Class IV and Cormack-Lehane grade IV extremely difficult endotracheal intubation. Neither glottis nor epiglottis was visible on laryngoscopy; resulting in failed placement of the double-lumen endobronchial tube (DLT) following numerous attempts. The DLT was eventually placed via GlideScope videolaryngoscopy. Whereas the endobroncheal right lung block for left OLV was successfully placed using fiberopticscopy. The crus habitus encroached on OLV tidal volume by the cranially displaced ascending colon and left kidney. Anesthesia was maintained with remifentanil /sevoflurane; adjusted to maintain bispectral index (BIS) at 40–60. Digitally recorded BIS was 38–62 except when BIS precipitously declined to 14–38 (SR, suppression ratio < 10) for 25 min after termination of the cardiopulmonary bypass.ConclusionsWe report a case essentially dealing with an anatomically distorted difficult airway in a patient with left Bochdalek CDH undergoing a complex AVR. We describe anesthetic difficulties and unforeseen issues encountered; such as an extremely difficult DLT placement.

Long-Term Functional Outcomes at 1-Year After Hospital Discharge in Critically Ill Neonates With Congenital Diaphragmatic Hernia.

Congenital diaphragmatic hernia (CDH) is a birth defect associated with long-term morbidity. Our objective was to examine longitudinal change in Functional Status Scale (FSS) after hospital discharge in CDH survivors. Single-center retrospective cohort study. Center for comprehensive CDH management at a quaternary, free-standing children's hospital. Infants with Bochdalek CDH were admitted to the ICU between January 2009 and December 2019 and survived until hospital discharge. None. One hundred forty-two infants (58% male, mean birth weight 3.08 kg, 80% left-sided defects) met inclusion criteria. Relevant clinical data were extracted from the medical record to calculate FSS (primary outcome) at hospital discharge and three subsequent outpatient follow-up time points. The median (interquartile range [IQR]) FSS score at hospital discharge was 8.0 (7.0-9.0); 39 patients (27.5%) had at least moderate impairment (FSS ≥ 9). Median (IQR) FSS at 0- to 6-month ( n = 141), 6- to 12-month ( n = 141), and over 12-month ( n = 140) follow-up visits were 7.0 (7.0-8.0), 7.0 (6.0-8.0), and 6.0 (6.0-7.0), respectively. Twenty-one patients (15%) had at least moderate impairment at over 12-month follow-up; median composite FSS scores in the over 12-month time point decreased by 2.0 points from hospital discharge. Median feeding domain scores improved by 1.0 (1.0-2.0), whereas other domain scores remained without impairment. Multivariable analysis demonstrated right-sided, C- or D-size defects, extracorporeal membrane oxygenation use, cardiopulmonary resuscitation, and chromosomal anomalies were associated with impairment. The majority of CDH survivors at our center had mild functional status impairment (FSS ≤ 8) at discharge and 1-year follow-up; however, nearly 15% of patients had moderate impairment during this time period. The feeding domain had the highest level of functional impairment. We observed unchanged or improving functional status longitudinally over 1-year follow-up after hospital discharge. Longitudinal outcomes will guide interdisciplinary management strategies in CDH survivors.

Right Bochdalek congenital diaphragmatic hernia: a tertiary center\u2019s experience over 13 years

BackgroundRight Bochdalek congenital diaphragmatic hernia (RB-CDH) is far less common than left Bochdalek congenital diaphragmatic hernia, accounting for only 13% of cases. There are limited published data on the outcomes and survival rate of RB-CDH.We aimed at investigating the clinical characteristics and analyzing the risk factors of survival in neonates with RB-CDH treated in our center over a period of 13 years.ResultsFifteen infants with RB-CDH were identified. Most of the patients were full term (74%). The mean birth weight was 2.90± 0.72 kg. The ratio of male to female was 2:1. The mean APGAR score at 1 min was 5.31±2.34, and 7.30±1.59 at 5 min. Ten patients (67%) were imaged by antenatal ultrasound. Eleven patients (73.33%) survived to go for surgical repair. The hernia sac was found in 5 patients (45%). Most hernial defects were closed in a primary fashion. The mean age at the operative repair was 8.11±9.90 days. The average NICU stay for all patients was 40.47±50.38 days. The mean follow-up period was 20.45±9.34 months. Three patients had postoperative complications. The total survival rate in neonates with RB-CDH was 9/15 (60%). Nine out of 11 (82%) neonates survived after surgical repair. Four patients (27%) died before surgical repair. Ventilation-related bilateral pneumothorax was a contributing cause of death in three patients. Birth weight was found lower in the non-survivor’s group (P < 0.05). Moreover, the degree of pulmonary hypertension was more severe among non-survivors. No statistical significance was observed between other variables and mortality.ConclusionWe found that low birth weight and the presence of severe PHTN were risk factors for mortality in neonates with RB-CDH. These results are in line with previous studies on prognostic factors in CDH. Ventilator-related pneumothorax appears to be a significant contributing cause of death. Long-term follow-up studies of infants born with RB-CDH are needed as small number of cases limits large-volume RB-CDH studies.

Human induced pluripotent stem cell-derived lung organoids in an ex vivo model of the congenital diaphragmatic hernia fetal lung.

Three‐dimensional lung organoids (LOs) derived from pluripotent stem cells have the potential to enhance our understanding of disease mechanisms and to enable novel therapeutic approaches in neonates with pulmonary disorders. We established a reproducible ex vivo model of lung development using transgene‐free human induced pluripotent stem cells generated from fetuses and infants with Bochdalek congenital diaphragmatic hernia (CDH), a polygenic disorder associated with fetal lung compression and pulmonary hypoplasia at birth. Molecular and cellular comparisons of CDH LOs revealed impaired generation of NKX2.1+ progenitors, type II alveolar epithelial cells, and PDGFRα+ myofibroblasts. We then subjected these LOs to disease relevant mechanical cues through ex vivo compression and observed significant changes in genes associated with pulmonary progenitors, alveolar epithelial cells, and mesenchymal fibroblasts. Collectively, these data suggest both primary cell‐intrinsic and secondary mechanical causes of CDH lung hypoplasia and support the use of this stem cell‐based approach for disease modeling in CDH.

The management of Bochdalek congenital diaphragmatic hernia: a single center experience and review of the literature

Objectives: Congenital diaphragmatic hernia (CDH) is a rare congenital anomaly of the diaphragm with pulmonary hypoplasia and persistent pulmonary hypertension and has serious consequences. Despite recent diagnosis and treatment strategies, CDH is still a challenging condition. We aim to present our clinical experiences of CDH, and review of the literature. Methods: Data of CDH patients who were operated in our clinic between January 2010 and September 2018 were obtained from the patient's chart. The clinical course and results of the patients with Bochdalek type CDH were reviewed. Results: We performed diaphragmatic closure in 16 patients with Bochdalek CDH during study period. Fourteen (82%) cases were diagnosed antenatally. In 5 (29%) patients, preoperative pulmonary hypertension developed and nitric oxide was administered. Twelve of the sixteen patients (75%) underwent primary repair and 4 of them underwent prosthetic patch. Three patients were repaired thoracoscopically. Five (31%) patients died due to severe persistent pulmonary hypertension on postoperative period. There was no recurrence in our patients who were followed-up for a mean of 27 months. Conclusion: In the management of Bochdalek CDH, the clinical success has been increasing in parallel with the important developments with the application of new treatment modalities in the neonatal intensive care units and new surgical techniques in recent years.

Right congenital diaphragmatic hernia: Four cases and literature review

Background: Left-sided Bochdalek congenital diaphragmatic hernia (CDH) is the most common type of CDH. The right-sided Bochdalek CDH is rare and usually contains only the liver as its content. We describe four children with right CDH managed at our institution over 3 years. Materials and Methods: We present a retrospective analysis of four patients with right CDH managed at our institution from 2012 to 2015 with respect to age at presentation, sex, presenting symptoms, investigations, associated anomalies, management, and outcome. Results: The average age at presentation was 1.5 years, with range being 5 days to 4 years. The three older children presented with a history of frequent respiratory tract infections. The neonate was a preterm low-birth weight baby and had respiratory distress since birth. A chest radiograph suggested right pneumothorax for which intercostal chest drain insertion was done. A repeat chest X-ray showed suspicion of right-sided CDH which was confirmed on computerized tomography. All four patients underwent right thoracotomy with repair of the CDH. The neonate expired on the 4th postoperative day. The other three children had an uneventful postoperative recovery. Conclusion: Right-sided CDH is rare and has varied presentations and poorer outcome.

The "Flat Diaphragm": Does the Degree of Curvature of the Diaphragm on Postoperative X-Ray Predict Congenital Diaphragmatic Hernia Recurrence?

The appearance of the diaphragmatic curvature and the rib insertion level of the diaphragm on postoperative chest X-ray (CXR) may predict recurrence. Our purpose was to examine the relationship between the curvature of the diaphragm on postoperative CXR and recurrence. We performed a retrospective review of left-sided, Bochdalek congenital diaphragmatic hernia (CDH) surgical repairs from 2004 to 2015 at a single institution. We developed a tool to measure the flatness of the diaphragm on postoperative CXR, termed the diaphragmatic curvature index (τ). The primary outcome of interest was recurrence after surgical repair. Of the 127 patients identified, 54% (n = 69) had a primary repair, while 46% (n = 58) required a patch repair. The overall recurrence rate was 21.3% (n = 27). There was no difference in median lateral rib insertion level in patients with and without recurrence or those who had a primary or patch repair. The overall median diaphragmatic curvature index was 6.29 (interquartile range [IQR] 5.30-8.09) and was not significantly different among patients who had a recurrence (6.00, IQR 5.34-8.24) and those who did not (6.46, IQR 5.24-8.07) (P = .853). Within the primary repair group (6.34 versus 6.93, P = .84) and the patch repair group (5.59 versus 6.18, P = .46), the median diaphragmatic curvature index was not different among patients who had a recurrence and those who did not. A flat appearance of the diaphragm on postoperative CXR as measured by the median diaphragmatic curvature index (τ) is not associated with recurrence. The shape of the diaphragm on CXR after CDH repair may not be predictive of recurrence as previously thought.

Bilious emesis as presenting symptom of congenital diaphragmatic hernia in an 8-month-old

Abstract Although congenital diaphragmatic hernia (CDH) primarily presents in either the prenatal or neonatal period, late presentation has a reported incidence of 2.5–25%. This case report describes an 8-month-old-male who presented to the emergency department with dehydration and a 24-h history of bilious emesis. Work-up led to the diagnosis of a left-sided Bochdalek CDH. He subsequently underwent laparoscopic diaphragmatic hernia repair with reduction of near-total length of incarcerated bowel. The patient had an uneventful recovery. Babies born with CDH are typically unstable at birth, and even with repair, the mortality rate remains high. However, in the case of delayed CDH diagnosis where there are no perinatal issues, surgical repair has very high success rates, provided that there are no complications regarding the delay. If there is not a high index of suspicion based on the patient's history and exam, delayed diagnosis and intervention with late CDH presentations can lead to complications which could otherwise be minimized. The purpose of this case report is to raise awareness and contribute to the growing knowledge about delayed CDH presentation among physicians and surgeons to facilitate early diagnosis and care of a morbid yet manageable condition.

Percutaneous Transluminal Coronary Angioplasty in a Patient with Congenital Diaphragmatic Bochdalek Hernia

Herniations through the foramen of Bochdalek are very rare diaphragmatic hernias in adults. Even in infants, respiratory distress syndrome manifests as a complication of a disease, it may be asymptomatic until late in life. Although the presenceof atherosclerotic process do not differ from normal, angiographic characteristics of these vessels, such as the orifice configuration, exit angulation, the route of the artery and the location of the stenotic lesions are much more different. We report an extremely rare case of percutaneous treatment of a coronary stenosis in a patient whose heart was displaced to the right side of the chest due to congenital diaphragmatic Bochdalek hernia.

Sensorineural hearing loss in congenital diaphragmatic hernia survivors is associated with postnatal management and not defect size

Background/PurposeWe determined the incidence of sensorineural hearing loss (SNHL; >20dB at any frequency) in a contemporary cohort of congenital diaphragmatic hernia (CDH) survivors at a single tertiary care center and identified potential risk factors for SNHL. MethodsFrom 2000 through 2011, clinical and audiologic data were collected on 122 surgically-repaired Bochdalek CDH patients. CDH defect size, duration of ventilation, and cumulative aminoglycoside treatment were used for multivariate logistic regression. ResultsIncidence of SNHL was 7.4% (9/122). We identified one significant independent predictor of SNHL: cumulative length of aminoglycoside treatment (P<.001; OR 1.44, 95% CI: 1.13–1.83). ConclusionsOver the last decade, the incidence of SNHL in our CDH patients is low compared to previous reports in the literature (7.4%) and is not associated with CDH defect size or the need for extracorporeal membrane oxygenation. Prolonged duration of aminoglycoside treatment increases the risk of SNHL independent of defect size and duration of ventilation.

Utilization of a novel unidirectional knotless suture during minimal access procedures in pediatric surgery

BackgroundThe application of minimally invasive surgery (MIS) for advanced procedures in children is logical. However, the intracorporeal placement and tying of suture can be challenging, leading to prolonged anesthesia and morbidity. We describe our initial experience with the use of a novel unidirectional barbed knotless suture (V-LOC, Covidien, Mansfield, MA) that permits a safe and efficient advanced MIS reconstruction in infants and children. MethodsFrom August 2010 to February 2012, 11 infants and children underwent diaphragmatic reconstruction utilizing either the absorbable or the permanent V-LOC suture. Data retrieval included gender, weight, diagnosis, operative time, complications and follow up. ResultsThoracoscopic or laparoscopic repairs were carried out in all children. Two of the infants with congenital diaphragmatic hernia of Bochdalek (CDH) developed a recurrence at 4 and 6months of age and required reoperation. There were no other complications or recurrence in the remaining 9 children, and there were no mortalities in the group. ConclusionThis is the first study to evaluate the use of the unidirectional barbed knotless suture in pediatric surgery. We demonstrate that the use of the V-LOC barbed suture is an innovative, safe and time saving option for pediatric MIS. Prospective analysis with long-term follow-up is required to confirm these initial results and to ascertain if this novel approach can be utilized in other pediatric surgical conditions.

Minimal Access Surgery for Repair of Congenital Diaphragmatic Hernia: Is it Advantageous?—An Open Review

Congenital diaphragmatic hernia (CDH) is a congenital life-threatening condition requiring surgical repair in the neonatal period. Minimal access surgery (MAS) is gaining ground on the classical open approach by laparotomy or thoracotomy as it minimizes damage to the abdominal or thoracic wall. Using an open review of the literature, we aimed to determine whether MAS is safe and effective in treating CDH. Furthermore, we provide selection criteria for the optimal surgical approach, laid down in a decision algorithm. An online search of MEDLINE was performed (May 2012), followed by a citations search. All study types except case reports describing open and/or MAS repair of Bochdalek CDH were eligible. Primary outcome data, for example, surgical complications and mortality, were recorded, as well as secondary outcome measures, for example, operative time, duration of postoperative ventilation, tolerance of enteral nutrition, and total length of stay (LOS) in hospital. Analysis was performed in accordance with the standards of the Cochrane Handbook for Systematic Reviews of Interventions. We identified 15 relevant studies, 5 of them describing MAS only and 10 comparing MAS to open repair of CDH. Numbers of included patients and selection criteria for MAS varied widely. Most studies have methodological limitations, such as the use of retrospective data or historical control groups. ECMO treatment and patch use were more frequent in the open repair group (both p < 0.0001). Recurrence risk seemed to be increased in the MAS group. The need for conversion in MAS series ranged widely, from 3.4 to 75.0%. The risk of general surgical complications did not vary between groups. Mortality seemed to be less in the MAS group. Operative time seemed to be longer in the MAS group. Duration of postoperative ventilation and total LOS appeared to be reduced in this group and patients returned quicker to enteral nutrition. We demonstrate that MAS for diaphragmatic hernia appears to be safe in terms of complications and mortality. Besides, it is associated with faster postoperative recovery. Growing experience with this technique is expected to lower the recurrence risk and to shorten the operative time. These findings should be interpreted cautiously because of methodological limitations of the studies included. Selection criteria used in various studies are associated with an important risk of selection bias. Nonetheless, these criteria can be used to identify patients who will benefit most from MAS.

Maternal periconceptional exposure to cigarette smoking and alcohol consumption and congenital diaphragmatic hernia

Congenital diaphragmatic hernia (CDH) is a major birth defect that occurs when abdominal organs herniate through a diaphragmatic opening into the thoracic cavity and is associated with high mortality (>50%). The etiology of CDH is not well understood. Using data from the National Birth Defects Prevention Study, we examined associations between CDH and maternal periconceptional exposure (1 month before through the third month of pregnancy) to cigarette smoking and alcohol. Interview reports of exposures were provided by mothers of CDH (n = 503) and unaffected control (n = 6703) infants delivered from October 1997 through December 2005. Any exposure (yes/no), as well as quantity (average number of cigarettes or drinks), type (active/passive smoking; beer, wine, distilled spirits), and duration (e.g., number of months exposed) were examined. Adjusted odds ratios (aORs) and 95% confidence intervals (CIs) were calculated for all CDH cases combined, selected subtypes (Bochdalek, Morgagni, not otherwise specified), and phenotypes (infants with/without additional major birth defects). The aOR for any smoking was nonsignificantly elevated for all CDH cases combined. Odds of any smoking was significant for isolated Bochdalek CDH (aOR, 1.9; 95% CI, 1.2-3.0). The aORs associated with all measures of alcohol consumption were near unity for each CDH category examined. Stratification of smoking exposure by alcohol consumption and stratification of alcohol consumption by smoking exposure did not appreciably change the aORs. These findings identified periconceptional smoking exposure as a potential risk factor for CDH. Future studies need to confirm our findings and explore possible pathways accounting for the teratogenic effect of smoking.

Adult Bochdalek hernia simulating left pleural effusion: a review and a case report

The authors present a rare case of congenital diaphragmatic Bochdalek hernia in an adult stimulating left pleural effusion. The diagnosis of left pleural effusion was made on the basis of conventional chest X-ray and ultrasonography. The definitive diagnosis of Bochdalek hernia was made by left video-assisted thoracoscopy. The patient was successfully treated operatively by conventional surgery--a combination of left thoracotomy and median laparotomy. The reported case supported the view that Bochdalek hernia in adults presents usually with atypical chronic abdominal and respiratory symptoms. Surgical treatment should best be performed, according to the authors, by competent surgeons with good command of both the thoracic and abdominal approaches to the diaphragm.

Absolute vs relative improvements in congenital diaphragmatic hernia survival: what happened to “hidden mortality”

Purpose The aim of this study is to determine if there has been a true, absolute, or apparent relative increase in congenital diaphragmatic hernia (CDH) survival for the last 2 decades. Method All neonatal Bochdalek CDH patients admitted to an Ontario pediatric surgical hospital during the period when significant improvements in CDH survival was reported (from January 1, 1992, to December 31, 1999) were analyzed. Patient characteristics were assessed for CDH population homogeneity and differences between institutional and vital statistics-based population survival outcomes. SAS 9.1 (SAS Institute, Cary, NC) was used for analysis. Result Of 198 cohorts, demographic parameters including birth weight, gestational age, Apgar scores, sex, and associated congenital anomalies did not change significantly. Preoperative survival was 149 (75.2%) of 198, whereas postoperative survival was 133 (89.3%) of 149, and overall institutional survival was 133 (67.2%) of 198. Comparison of institution and population-based mortality (n = 65 vs 96) during the period yielded 32% of CDH deaths unaccounted for by institutions. Yearly analysis of hidden mortality consistently showed a significantly lower mortality in institution-based reporting than population. Conclusion A hidden mortality exists for institutionally reported CDH survival rates. Careful interpretation of research findings and more comprehensive population-based tools are needed for reliable counseling and evaluation of current and future treatments.

Should Intraoperative Hypercapnea or Hypercarbia Raise Concern in Neonates Undergoing Thoracoscopic Repair of Diaphragmatic Hernia of Bochdalek?

Better understanding of cardiopulmonary physiology in children with congenital diaphragmatic hernia of Bochdalek (CDH) has facilitated improved survival. In addition, it has allowed surgeons to employ minimally invasive techniques to their repair under conditions that might result in hypercarbia and/or recurrent pulmonary hypertension. Under institutional review board approval, the records of all neonates at a single institution who underwent thoracoscopic CDH (T-CDH) were reviewed with attention to the incidence of intraoperative hypercapnea (elevated end tidal CO(2)) or hypercarbia (increased PCO(2) by blood gas measurement) and any associated complications. From 2004 through 2007, 31 consecutive neonates, including those who had undergone extracorporeal membrane oxygenation, had T-CDH. CO(2) insufflation to 3 mm Hg was used until the viscera were reduced within the abdominal cavity. The operative technique and outcomes are described elsewhere. Preoperative analyses revealed a mean arterial PCO(2) of 53 +/- 11 torr and SaO(2) of 95 +/- 5%. The mean highest recorded intraoperative end-tidal CO(2) level was 64 +/- 13 and correlated poorly with the highest arterial PCO(2) (mean, 78 +/- 29 torr; range, 29-130). The mean lowest recorded intraoperative SaO(2) was 92 +/- 8% with only two values less than 88%. The average lowest intraoperative mean arterial blood pressure was 47 +/- 8 mm Hg (range, 34-70 mm Hg). No neonate received inhaled nitric oxide, intravenous buffer administration, or escalation of inotrope administration during the procedures nor did any experience recurrent pulmonary hypertension postoperatively. Hypercapnea and hypercarbia are common phenomena during T-CDH but do not appear to correlate with one another nor result in clinically evident recurrent pulmonary hypertension, hypoxemia, hypotension, need for support with vasoactive medications, inhaled nitric oxide, or buffering agents.

Endoscopic Repair of Late-Presenting Morgagni and Bochdalek Hernia in Children: Case Report and Review of the Literature

Delayed presentation of a congenital diaphragmatic hernia (CDH) is not usual. Primary laparoscopic repair is becoming the standard in many centers. Different approaches and techniques have been proposed. There is not enough evidence in the literature to recommend one technique over another. In this paper, we report one case of Morgagni hernia (MH) and one case of Bochdalek hernia (BH), 2 and 6 years old, respectively, operated on in our hospital. In the first case, the diaphragmatic defect was directly sutured with extracorporeal interrupted nonabsorbable sutures, passed through the abdominal wall with a Reverdin needle. In the second one, intracorporeal nonabsorbable stitches were placed. A search of the literature was made using PubMed and the following words: congenital diaphragmatic hernia, laparoscopy or thoracoscopy, and children. The neonatal Bochdalek hernias were discarded. Data about surgical approach, suturing technique, management of the hernia sac, complications, and recurrence were summarized for both pathologies. Both patients were discharged 48 hours after surgery. There were no complications. No recurrence was evident after 6 months. Eleven articles on the treatment of MHs were found, with a total of 30 patients. For BHs, 10 articles met the inclusion criteria, with a total of 54 patients. In both groups, all the papers were case reports or retrospective reviews of case series. The MH is best approached through laparoscopy, and the BH can be treated through thoracoscopy or laparoscopy. Most researchers prefer direct suture with nonabsorbable material. Both complication and recurrence rates are very low. The endoscopic approach of late-presenting Morgagni and Bochdalek CDH is a safe technique. It offers all the advantages of minimally invasive surgery (MIS), and laparoscopy also permits the diagnosis and treatment of other associated conditions. There are a short number of cases reported and no prospective study comparing open with the MIS approach for the treatment of diaphragmatic malformations.
