RESUMO
INTRODUCTION: Congenital diaphragmatic hernia (CDH) remains a therapeutic challenge. The surgical classification recommended by the Congenital Diaphragmatic Hernia study group (CDHSG), based on the size of the defect, is used for staging in reference centres. Larger defects are associated with poorer outcomes. Our aim was to describe and compare the morbidity at hospital discharge of newborns who underwent surgical correction of CDH at the Juan P. Garrahan, according to the surgical staging of the defect proposed by the CDHSG. MATERIAL AND METHODS: The study included patients with CDH admitted to the Juan P. Garrahan Hospital between 2012 and 2020, and we analysed the distribution, morbidity and mortality associated with the size of the defect. We carried out a descriptive analysis, calculating measures of central tendency and dispersion, and bivariate and multivariate analyses. RESULTS: A total of 230 patients with CDH were admitted and 158 underwent surgery. We found that defect sizes C and D sizes were associated with an increased risk of chronic pulmonary disease (CPD) (OR, 5.3; 95% CI, 2.2-13.4; P<.0000), need of extracorporeal membrane oxygenation (OR 3.9; 95% CI, 1.3-12.8; P<.005) and chylothorax (OR, 2.1; 95% CI, 0.8-6.4; P<.10]. The multivariate analysis revealed that a large defect size (C-D) was independently and significantly associated with CPD (OR 4.19; 95% CI, 1.76-9.95). CONCLUSION: Staging the defect according to de CDHSG classification during surgery allows the application of uniform management criteria and the prediction of patient outcomes and complications during the hospital stay.

INTRODUCTION: Mortality related to CDH is high, but with great variability among centers. There are few studies on patients with this condition born in South America which show poor outcomes. The goal of this study is to present the outcome of CDH in several high-volume quaternary centers in South America, ascertain the factors associated with lower mortality in our population, and compare our outcomes to those of the CDH Study Group (CDHSG). METHODS: The data from two South American centers were retrospectively analyzed and compared with contemporary data from other CDHSG participating centers. Patient demographic and clinical characteristics were also evaluated and compared. RESULTS: Between 2013 and 2018, the two South American centers saw 335 patients with CDH with an overall survival rate of 73.1%. Survival for the high, intermediate, and low-risk groups as determined by the Brindle score was 50%, 70%, and 87%, respectively. In our cohort the strongest predictors of mortality were ECMO use and early PaCO2. There were no significant differences in mortality between the two South American centers and the other CDHSG centers when adjusted by risk score, however, the South American centers had higher use of ECMO in the intermediate-risk group. DISCUSSION: Quaternary South American centers had similar outcomes to CDHSG centers worldwide. The availability and coordination of centralized dedicated care allow more efficient use of scarce technical and professional resources in patients with CDH. LEVEL OF EVIDENCE: III.

Introduction: Congenital diaphragmatic hernia (CDH) prevalence is low while its associated morbidity and mortality rates are high. Postnatal prognostic factors on the first day of life are useful for predicting the outcome. Objectives: To determine the mortality predictive ability of postnatal echocardiographic, clinical, and biochemical factors among newborn infants with CDH in their first day of life. Method: Observational analytical study of a retrospective cohort. Patients with CDH were consecutively included between March 2012 and November 2018. On the first day of life, analyzed predictors were the oxygenation index (OI), the highest partial pressure of carbon dioxide (pCO2) level in blood, the SNAPPE II severity score, the echocardiography, and the N-terminal pro-B-type natriuretic peptide (NTproBNP) value. Results: The population consisted of 178 patients with CDH. Survival was 75 %. Extracorporeal membrane oxygenation was used in 24 %. The early onset of systemic or suprasystemic pulmonary hypertension showed no predictive ability (OR: 2.2, 95 % CI: 0.8-8), p = 0.1. NT-proBNP did not show good discrimination either (area under the curve [AUC]: 0.46, p = 0.67). The OI, SNAPPE II score, and the highest pCO2 level showed adequate discrimination power, AUC for OI: 0.82, AUC for SNAPPE II: 0.86, and AUC for pCO2: 0.75, p < 0.001. Conclusion: The SNAPPE II score, the OI, and the highest pCO2 level measured on the first day of life, showed a good predictive ability in terms of the course of the disease; the SNAPPE II score was better than the OI and the highest pCO2 level.
