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.

RESUMO

La hernia diafragmática congénita es una discontinuidad del diafragma con herniación de los órganos abdominales a la cavidad torácica, actualmente se postula una hipótesis dual para su origen. Su fisiopatología está determinada por la hipoplasia pulmonar, la hipertensión pulmonar y la disfunción ventricular, entender estos elementos es necesario para un adecuado manejo y la mejoría del pronóstico.

Congenital diaphragmatic hernia is a discontinuity of the diaphragm with herniation of the abdominal organs into the thoracic cavity, currently a dual hypothesis for its origin is postulated. Its pathophysiology is determined by pulmonary hypoplasia, pulmonary hypertension and ventricular dysfunction, understanding these elements is necessary for adequate management and improve prognosis.

RESUMO

Resumen Una hernia diafragmática congénita ocurre cuando existe un defecto estructural en el diafragma que permite la migración de los órganos abdominales a la cavidad torácica. Se considera de presentación tardía cuando se diagnostica después de los 30 días de vida extrauterina. Más del 60% de los pacientes con hernia diafragmática congénita cuentan con un diagnóstico erróneo al momento del nacimiento, encontrándose dentro de los diagnósticos más frecuentes al derrame pleural, neumonía, neumotórax, neumatocele y absceso pulmonar. Presentamos el caso de una paciente del sexo femenino de 3 años que acudió a urgencias por dolor abdominal, náuseas, vómito, intolerancia a la vía oral y dificultad respiratoria. La radiografía de tórax evidenció migración de la cámara gástrica hacia el tórax, dessplazamiento de la silueta cardiaca y las estructuras del mediastino hacia la derecha con la punta de la sonda nasogástrica ubicada en el hemitórax izquierdo. Se concluyó el diagnóstico de hernia diafragmática de presentación tardía. La paciente recibió tratamiento quirúrgico, el cual fue exitoso. Este trabajo destaca la importancia de sospechar el diagnóstico de hernia diafragmática congénita de presentación tardía cuando se abordan pacientes pediátricos con dificultad respiratoria sin otra causa aparente, dolor abdominal, náuseas y vómito.

Abstract A congenital diaphragmatic hernia occurs when the diaphragm has a structural defect that allows the migration of abdominal organs into the chest cavity. It is called late presentation when its diagnosis does after 30 days of life. More than 60% of patients with congenital diaphragmatic hernia are misdiagnosed. The most common misdiagnoses are pleural effusion, pneumonia, pneumothorax, pneuma tocele, and lung abscess. We present a case of a 3-year-old female who attended the emergency room due to abdominal pain, nausea, vomiting, intolerance to the oral route, and respiratory distress. The chest X-ray showed migration of the gastric chamber towards the thorax, displacement of the cardiac silhouette and the mediastinal structures to the right, and the tip of the nasogastric tube located in the left hemithorax. The doctors concluded a late presentation diaphragmatic hernia. The patient received surgical treatment, which was successful. This paper highlights the importance of suspecting the diagnosis of late-onset congenital diaphragmatic hernia when treating pediatric patients with respiratory distress without another apparent cause, abdominal pain, nausea, and vomiting.

RESUMO

Background: Peritoneopericardial diaphragmatic hernia is a rare pathogenesis of congenital origin, which occurs due to a failure in the communication between the diaphragm and the pericardium during embryogenesis. Symptoms may be non-existent or non-specific, depending on the herniated organ involved and, in most cases, the diagnosis is incidental. Regarding the most indicated treatment, there are still divergences in the literature concerning the indication of conservative or surgical treatment. This study reports the case of a feline peritoneopericardial hernia, for which surgical correction was the treatment of choice. Case: A 3-month-old female kitten, no defined racial pattern, was referred to the Veterinary Hospital of the Federal Rural University of Pernambuco for treatment of a peritoneopericardial diaphragmatic hernia. This condition was diagnosed through radiographic examination after the patient having been submitted to pediatric castration and presented anesthetic complications in the transsurgery. Blood count, biochemical profile and Doppler echocardiogram were performed, which showed no significant changes. To obtain a better study and surgical planning, computed tomography was performed to observe the heart located cranially in the pericardial cavity. Caudally to the heart, hepatic parenchyma located in the pericardial cavity was observed; and hepatic vessels presenting slightly enlarged dimensions. These tomographic findings suggested peritoneopericardial diaphragmatic hernia; being the liver present in the pericardial cavity and signs of congestion in the hepatic parenchyma. Due to the likelihood of future worsening of the hernia, surgical correction was performed, with an abdominal midline incision in the preumbilical region to reposition the liver to its normal anatomy, followed by diaphragm reconstitution through a herniorrhaphy. After the surgical procedure, the patient was referred for observation in internment and, after 15 days, the skin sutures were removed. Complete correction of the hernial defect was observed on radiography performed 30 days after the surgical procedure. However, the examination showed the presence of deviation/ deformity in the topography of the sternum and costal cartilages, with slight cardiac displacement to the right hemithorax, suggesting the presence of pectus excavatum. Discussion: Peritoneopericardial diaphragmatic hernia is considered rare and, despite being one of the most common causes of congenital pericardial anomaly in felines, it has a low prevalence ranging from 0.06% to 1.45%. They are usually diagnosed from two years of age, with prevalence for older animals. However, due to having presented anesthetic changes, the patient of this case report could be diagnosed early. Among the most common organs that migrate to the thoracic cavity, the liver is the most commonly observed, which is also the hernia content of the present report. Peritoneopericardial hernia is often diagnosed through radiography and ultrasound, and these imaging tests proved to be sufficient for the diagnosis in this report. However, computed tomography was important for providing a better study of case and for the adoption of median celiotomy as a treatment. Associations with other malformations are described in the literature, with pectus excavatum being the most common and also observed in this report. Peritoneopericardial diaphragmatic hernia is a rare anomaly, rarely reported in the literature and with divergences regarding its treatment. The adoption of early surgical treatment performed in this report showed satisfactory evolution and the possibility of a favorable prognosis.

RESUMO

Introducción: La hernia diafragmática surge como resultado del movimiento de los órganos abdominales hacia el tórax a través de un defecto del diafragma resultante de varios tipos de lesiones, que a menudo representan un desafío diagnóstico y terapéutico. La hernia diafragmática traumática es una enfermedad infrecuente. El trauma diafragmático rara vez es aislado, la mayoría de las veces se acompaña de otras lesiones toracoabdominales, cerebrales o musculoesqueléticas, siendo estas comorbilidades más graves responsables del mal pronóstico y aumento de la mortalidad. Caso clínico: Anciana de 90 años de edad, hipertensa, quien inicia cuadro clínico 48 horas previas a su ingreso, cuando posterior a caída del plano de bipedestación presenta disminución del estado de consciencia, náuseas, vómitos y disnea en reposo. Rx de tórax evidencia asas intestinales en hemitórax derecho. Se realizó laparotomía exploradora. Conclusión: Las hernias diafragmáticas traumáticas son infrecuentes, con incidencia <3%, sintomatología inespecífica y relacionadas generalmente con lesiones asociadas al trauma. Siempre se debe sospechar de una HD ante un paciente con antecedente de trauma cerrado de alto impacto o penetrante, en función de la cinética y mecanismo de lesión. El diagnóstico supone un reto para el cirujano, debiendo apoyarse en una firme sospecha y estudios radiológicos. Su tratamiento es quirúrgico, debiendo ser individualizado, con abordajes torácicos o abdominales en función del caso. La técnica a emplear dependerá de las características del defecto, de la fase del diagnóstico y la experiencia del equipo quirúrgico(AU)

Introduction: Diaphragmatic hernia arises as a result of the movement of the abdominal organs towards the thorax through a defect in the diaphragm resulting from various types of injuries, which often represent a diagnostic and therapeutic challenge. Traumatic diaphragmatic hernia is a rare disease. Diaphragmatic trauma is rarely isolated, most of the time it is accompanied by other thoracoabdominal, brain or musculoskeletal injuries, these more serious comorbidities being responsible for the poor prognosis and increased mortality. Clinical case: A 90-year-old woman with hypertension , who began a clinical picture 48 hours prior to admission, when after falling from the standing plane he presented a decreased state of consciousness, nausea, vomiting, and dyspnea at rest. Chest x-ray shows intestinal loops in the right hemithorax. Exploratory laparotomy was performed. Conclusion: Traumatic diaphragmatic hernias are rare, with an incidence of <3%, non-specific symptoms, and generally related to injuries associated with trauma. HD should always be suspected in a patient with a history of high-impact or penetrating blunt trauma, depending on the kinetics and mechanism of injury. Diagnosis is a challenge for the surgeon, and must be based on a firm suspicion and radiological studies. Its treatment is surgical, and must be individualized, with thoracic or abdominal approaches depending on the case. The technique to be used will depend on the characteristics of the defect, the diagnostic phase and the experience of the surgical team(AU)

RESUMO

RESUMEN La hernia diafragmática traumática se define como el paso del contenido abdominal a la cavidad torácica a través de un defecto en el diafragma producido por un trauma. Su diagnóstico es difícil, a menudo puede pasar inadvertido, debido a la gravedad de las lesiones que le acompañan. Las claves para el diagnóstico son un alto grado de sospecha y el conocimiento de los distintos signos en la tomografía computarizada. Una vez diagnosticada la ruptura diafragmática, se repara quirúrgicamente para evitar complicaciones. Se presenta el caso de un paciente masculino, de 88 años de edad con antecedentes de haber sufrido trauma toracoabdominal cerrado hacía 35 años, que acudió con un cuadro clínico de oclusión intestinal. Se publica este caso porque, además de ser una entidad poco frecuente, resulta importante el conocimiento de esta enfermedad, para valorarla dentro de las posibilidades diagnósticas en aquellos pacientes que aquejen síntomas relacionados con sus complicaciones.

ABSTRACT Traumatic diaphragmatic hernia is defined as the passage of abdominal contents into the thoracic cavity through a defect in the diaphragm caused by trauma. The diagnosis of traumatic diaphragmatic hernia is difficult, it can often go unnoticed, due to the seriousness of the accompanying injuries. The keys to diagnosis are a high degree of suspicion and knowledge of the various signs on computed tomography. Once the diaphragmatic rupture is diagnosed, it is surgically repaired in order to avoid complications. The case of an 88-year-old male patient with a history of having suffered closed thoracoabdominal trauma 35 years earlier, who presented with a clinical picture of intestinal obstruction is presented. This case is published because, in addition to being a rare entity, knowledge of this disease is important, in order to assess it within the diagnostic possibilities, in those patients who suffer from symptoms related to its complications

RESUMO

ABSTRACT Introduction: diaphragmatic injury is a challenge for surgeons. It is an injury that can be isolated. It is frequent in penetrating thoracoabdominal trauma. It represents a diagnostic challenge and the ideal approach is not yet well established. The occurrence of spontaneous healing of these injuries is still much discussed and even more, if it does, what is the healing mechanism? Objective: to macroscopically and histologically evaluate the natural evolution of perforation and cutting wounds equivalent to 30% of the left diaphragm. Method: 50 specimens of rats underwent a surgical procedure and, after 30 days, were euthanized and those that presented scar tissue in the diaphragm, the samples were submitted to histopathological study, using the hematoxylin and eosin stains, Massons trichrome and Picrosirius to assess the presence of collagen or muscle fibers (hyperplasia) in the scar. Results: it was found that healing occurred in diaphragmatic injuries in 90% of rats. We also observed the presence of fibrosis in all analyzed samples. Conclusion: Spontaneous healing occurred in most diaphragmatic injuries and the inflammatory reaction represented by the presence of fibrosis and collagen deposition was observed in all our samples. Muscle fiber hyperplasia did not occur.

RESUMO Introdução: o ferimento diafragmático é um desafio para os cirurgiões. É uma lesão que pode ser isolada. É frequente nos traumas penetrantes toracoabdominais. Representa um desafio diagnóstico e a conduta ideal ainda não está bem estabelecida. A ocorrência da cicatrização espontânea dessas lesões é ainda muito discutida e mais ainda, se ocorre, qual o mecanismo de cicatrização? Objetivo: avaliar macroscopicamente e histologicamente a evolução natural das feridas perfuro cortantes equivalentes a 30% do diafragma esquerdo. Método: 50 espécimes de ratos, foram submetidos a procedimento cirúrgico e, após 30 dias, foram submetidos à eutanásia e aqueles que apresentaram tecido cicatricial no diafragma, as amostras foram submetidas a estudo histopatológico, usando as colorações de hematoxilina e eosina, tricrômico de Masson e Picrossirius para avaliar a presença de colágeno ou de fibras musculares (hiperplasia) na cicatriz. Resultados: verificou-se que ocorreu nas lesões diafragmáticas, a cicatrização em 90% dos ratos. Observamos também, a presença de fibrose em todas as amostras analisadas. Conclusão: ocorreu cicatrização espontânea na maioria das lesões diafragmáticas e a reação inflamatória representada pela presença de fibrose e deposição de colágeno foi observada em todas as nossas amostras. Não ocorreu hiperplasia de fibras musculares.

RESUMO

Resumen La hernia diafragmática congénita es un defecto en la formación del diafragma con una alta mortalidad y morbilidad para el recién nacido. La ubicación en el lado derecho corresponde a solo el 10% de todos los casos y se asocia con una menor supervivencia, especialmente cuando hay una herniación hepática. No se conoce con precisión el porcentaje de casos de hernia diafragmática congénita derecha que no implican una herniación hepática. Aun no hay certeza del tiempo estimado para obtener el mayor beneficio de la corrección quirúrgica, en nuestro caso realizado con éxito a los 2 días de vida, logrando previamente una adecuada estabilidad hemodinámica y ventilatoria. El manejo perioperatorio en unidad de cuidado intensivo neonatal, es fundamental para reducir la morbimortalidad asociada. Se presenta un caso de hernia diafragmática congénita derecha tratado con éxito y se exponen los aspectos más relevantes del manejo médico-quirúrgico de esta patología. MÉD.UIS.2021;34(3): 71-7.

Abstract Congenital diaphragmatic hernia is a congenital defect in the formation of the diaphragm with high mortality and morbidity for the newborn. The location on the right side corresponds to only 10% of all cases and is associated with a lower survival, especially when there is a liver herniation. The percentage of cases of right congenital diaphragmatic hernia that do not involve liver herniation is not known with precision. An estimated time to obtain the greatest benefit from surgical correction is not known with certainty, in our case it was carried out successfully at 2 days of life, previously achieving adequate hemodynamic and ventilatory stability. Perioperative management in the neonatal intensive care unit is essential to reduce the associated morbidity and mortality. A case of congenital right diaphragmatic hernia treated successfully is presented and the most relevant aspects of the medical-surgical management of this pathology are exposed. MÉD.

RESUMO

Abstract Diaphragmatic hernia during pregnancy or puerperium are rare entities that, in the event of a complication, represent a life-threatening emergency for both mother and the unborn child. Resolution in many cases requires a combined access through the thoracic and abdominal cavity to manage the complica tions of necrosis and/or perforation of an abdominal viscera. To treat the thoracic cavity, thoracotomy is the most described approach. Even more, the minimally invasive access by video-assisted thoracic surgery (VATS) is not widely referenced in the literature despite its clear benefits of this technique in the recovery of patients, even in emergencies. We present the case of a postpartum right diaphragmatic hernia, complicated by necrosis of the colonic wall, treated by combined VATS approach and laparotomy in the emergency.

Resumen Las hernias diafragmáticas durante el embarazo o puerperio son entidades raras que, en caso de complicación, representan una emergencia potencialmente mortal tanto para la madre como para el feto. La resolución en muchos casos requiere un acceso combinado a través de la cavidad torácica y abdominal para manejar las complicaciones de la necrosis o perforación de las vísceras abdominales. Para tratar la cavidad torácica, la toracotomía es la vía más descrita. Más aún, el acceso mínimamente invasivo mediante cirugía torácica video-asistida (VATS) no está ampliamente referenciado en la literatura a pesar de los claros beneficios de esta técnica en la recuperación de los pacientes, incluso en emergencias. Presentamos el caso de una hernia diafragmática derecha posparto, complicada por necrosis de la pared colónica, tratada combinado VATS y laparotomía en la urgencia.

RESUMO

Background: Peritoneopericardial diaphragmatic hernia is a congenital defect characterized by an anomalous communication between the abdominal cavity and pericardial sac, which can lead to displacement of the abdominal viscera into the thoracic cavity. The occurrence in felines is higher among long-haired breeds, mainly the Persian breed, possibly based onan autosomal recessive inheritance. The diagnosis of PPDH is performed by means of chest radiography with or without contrast, in association with other imaging tests such as ultrasonography and echocardiography. Our objective in this study was to report the occurrence and macroscopic changes in a case of peritoneopericardial diaphragmatic hernia in a Persian feline. Case: A 9-year-old male Persian cat weighing 3.4 kg was referred to the HPET-Private Veterinary Clinic, Salvador, Bahia, with an history of weight loss and chronic intermittent vomiting during the preceding 6 months, with lateral decubitus and breathing difficulties. Ultrasonography revealed findings suggestive of an infiltrative process in the stomach and duodenum, enlarged gastric lymph nodes, and some nodular images indicating slight displacement of the liver. Chest radiography revealed a cardiac silhouette with markedly enlarged dimensions associated with a dorsal deviation of the terminal trachea, and echocardiography revealed a small amount of pericardial effusion. The patient showed initial clinical improvement after blood transfusion; however, after 2 days, he exhibited significant clinical worsening and was therefore euthanized with the owner's consent. Post mortem evaluation revealed partial herniation of the liver and gallbladder into the chest cavity through a diaphragmatic hernia ring. The heart was partially surrounded by the left medial lobe of the liver, which was displaced into the pericardial sac. Herniated hepatic lobes had an irregular capsular surface with evident lobulation and tension lipidosis. In the abdominal cavity, the remainder of the liver (right lateral and medial lobes) was observed to be slightly enlarged, with an irregular surface, diffusely reddish with intense evidence of the lobular pattern and white and firm multifocal areas (fibrosis). In the duodenum, close to the pylorus, there was a nodule measuring 2.8 x 2.5 x 1.0 cm, with a whitish and ulcerated surface. When cut, it was soft and exhibited a homogeneous, whitish compact surface. Histopathological examinationshowed marked proliferation of fibrous connective tissue, which for the most part separated the lobes by septa and surrounded the portal space (fibrosis), a marked diffuse chronic inflammatory infiltrate composed of lymphocytes and plasma cells. In addition, marked bile duct hyperplasia and multifocal areas of fatty degeneration (steatosis). Discussion: The diagnosis was based on the association of clinical and pathological findings. Considering the age and clinical signs presented by the patient in this report, as well as the presence of few radiographic signs that were indicative of PPDH, the first differential diagnosis thought was pericardial neoplasia. Peritoneopericardial diaphragmatic hernia in felines is always of congenital origin and may occur asymptomatically depending on the number and involvement of herniated viscera. In this case, the patient's diagnosis of peritoneopericardial hernia was a necropsy finding; the fact that in agreement with previous reports of high rates of incidental diagnoses reinforces the importance of performing necropsy for confirmation or diagnosis of unexpected pathologies. In the present case, peritoneopericardial diaphragmatic hernia in isolation may not have led to severe anemia that culminated in the patient's death. The anatomopathological findings were compatible with biliary cirrhosis and multifocal liver fibrosis, accompanied by the presence of anemia and consequent hypovolemia.

RESUMO

Resumen Objetivo: Investigar con cuál técnica quirúrgica, cierre directo o con parche de Goretex, las hernias diafragmáticas congénitas operadas tienen más recidiva. Metodología: Los datos de los pacientes sometidos a reparación por hernia diafragmática congénita en el Hospital Nacional de Niños, entre enero 2008 y el 31 diciembre de 2017, fueron revisados retrospectivamente. De los 94 pacientes, solo 59 cumplen con los criterios de inclusión. Para la comparación de las variables cuantitativas se empleó pruebas de T de Student e intervalos de confianza al 95 %; las variables cualitativas se analizaron por la prueba de Fisher con un nivel de significancia de 0,05. Resultados: La mayoría de las hernias diafragmáticas operadas fueron izquierdas (78 %) y posterolaterales (91 %). La técnica de reparación más frecuente utilizada fue el cierre directo (68%). Hubo más recidivas posteriores a cierre con parche de Goretex. Se presentaron entre 1 y 12 meses postoperatorio. No hubo diferencia estadísticamente significativa entre recidivas con técnica de cierre directo versus cierre con parche de Goretex. Conclusión: Realizar un cierre directo del diafragma es una buena opción quirúrgica para reparación de hernia diafragmática congénita. No hubo en este estudio diferencias estadísticamente significativas en cuanto a recidiva entre utilizar técnica con cierre directo o con parche.

Abstract Objective: To investigate with which surgical technique, direct closure or use of a Goretex patch, congenital diaphragmatic hernias recurre more. Methodology: The data of the patients who underwent repair of congenital diaphragmatic hernia at the National Children's Hospital from January 2008 to December 31, 2017, were reviewed retrospectively. Of the 94 patients, only 59 met the inclusion criteria. For the comparison of the quantitative variables, Student's t-test and 95% confidence intervals were used, the qualitative variables were analyzed by the Fisher's test with a significance level of 0.05. Results: Most of the operated diaphragmatic hernias were left 78% and posterolateral 91%. The most frequent repair technique used was direct closure, 68%. There were more recurrences after closing when a Goretex patch was used. They occurred between 1 and 12 months post-operatively. There was no statistically significant difference between recurrences with the direct closure technique versus closure with the Goretexpatch. Conclusion: Performing a direct closure of the diaphragm is a good surgical option for surgical repair of congenital diaphragmatic hernias. There were no statistically significant differences in relapse in this study between using the direct closure or patch technique.

RESUMO

La hernia diafragmática traumática representa un reto al momento del diagnóstico. Una detección oportuna permite establecer un correcto tratamiento quirúrgico. Se presenta el caso de un paciente masculino de 37 años de edad con antecedente de trauma torácico por arma blanca 4 años antes; quien acude por cuadro de dolor abdominal intenso localizado en epigastrio que se irradia a hipocondrio izquierdo de aparición súbita 72 horas antes de su ingreso. Al examen físico murmullo vesicular disminuido en campo pulmonar izquierdo, y abdomen doloroso a la palpación a nivel de epigastrio e hipocondrio izquierdo. En exámenes de laboratorio no se evidencian alteraciones, mientras que la tomografía reporta hernia diafragmática izquierda; la misma que fue resuelta quirúrgicamente mediante técnica laparoscópica.

Traumatic diaphragmatic hernia represents a challenge at diagnosis. A timely detection allows to establish a correct surgical treatment. It is presented the case of a 37-year-old male patient with a history of stabbing chest trauma 4 years earlier; who comes for symptoms of intense abdominal pain located in the epigastrium that radiates to the left hypochondrium of sudden onset 72 hours before admission. On physical xamination, vesicular murmur decreased in the left lung field, and a painful abdomen on palpation at the level of the epigastrium and left hypochondrium were showed. Laboratory tests did not show any alterations, but tomography reports a left diaphragmatic hernia; this one was solved surgically by laparoscopic technique.

RESUMO

La hernia diafragmática congénita (HDC) es una enfermedad de baja prevalencia, con elevada morbimortalidad. Los factores pronósticos posnatales, durante el primer día de vida, son útiles para la toma de decisiones.Objetivos. Determinar la capacidad predictiva de los factores posnatales ecocardiográficos, clínicos y bioquímicos de mortalidad en los recién nacidos con HDC durante el primer día de vida.Método. Estudio observacional analítico de cohorte retrospectiva. Se incluyeron los pacientes con HDC, en forma consecutiva, desde marzo de 2012 a noviembre de 2018. Se analizaron como predictores el índice de oxigenación (IO), valor más alto de presión parcial de dióxido de carbono en sangre (pCO2), puntaje de gravedad SNAPPE II, ecocardiograma, dosaje de NT-pro péptido natriurético B (NT-proPNB), todos medidos en el primer día de vida.Resultados. La población fue de 178 pacientes con HDC. La sobrevida, del 75 %. El 24 % recibió oxigenación por membrana extracorpórea. La presencia precoz de hipertensión pulmonar sistémica o suprasistémica no mostró capacidad predictiva (OR 2,2; IC 95 %: 0,8-8), p = 0,1. NT-proPNB tampoco mostró buena discriminación (área bajo la curva (ABC) 0,46, p = 0,67). El IO, SNAPPE II y el valor más alto de pCO2 mostraron buena discriminación, ABC IO 0,82, ABC SNAPPE II 0,86 y ABC pCO2 0,75, p < 0,001.Conclusión.SNAPPE II, IO y valor más alto de pCO2, medidos el primer día de vida, mostraron buena capacidad predictiva con respecto a la evolución; SNAPPE II fue superior al IO y al valor más alto de CO2.

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.

RESUMO

Introducción. La hernia diafragmática congénita presenta alta morbimortalidad. Existen herramientas para predecir sobrevida, tanto prenatal (índice pulmón-cabeza observado/esperado ­observed/expected lung-to-head ratio; OE-LHR, por sus siglas en inglés­, presencia de hígado en tórax) como posnatal (puntaje del Grupo de Estudio sobre Hernia Diafragmática Congénita, Congenital Diaphragmatic Hernia Study Group, CDHSG). El objetivo fue identificar factores de riesgo asociados a mortalidad y estimar la mortalidad ajustada por riesgo prenatal en el subgrupo de pacientes con hernia izquierda aislada.Población y métodos. Estudio retrospectivo y analítico de pacientes nacidos en el Hospital Italiano de Buenos Aires durante 2011-2018. Se realizó un análisis multivariable para evaluar factores de riesgo asociados a mortalidad. Para la mortalidad ajustada por riesgo prenatal, se realizó una razón entre la mortalidad observada y la media "esperada" según el OE-LHR.Resultados. Se incluyeron 53 pacientes. La mediana de edad gestacional fue 38 semanas, y la media de peso al nacer, 3054 gramos. El 73 % de los pacientes tuvo hernia aislada. La mortalidad global fue del 45 %, mayor en pacientes con malformaciones asociadas. En el análisis multivariable, la presencia de hipertensión pulmonar grave estimada por ecocardiografía postnatal se asoció en forma independiente a mortalidad: (odds ratio ajustado 6,4; IC 95 %: 1,02-40). La mortalidad global observada en pacientes con hernia izquierda aislada fue similar a la esperada (razón 1,05).Conclusión. La mortalidad global es similar a la esperada según el OE-LHR. En nuestra población, la hipertensión pulmonar grave luego del nacimiento resultó determinante de la mortalidad.

Introduction. Morbidity and mortality are high in congenital diaphragmatic hernia. Some tools help to predict survival, both prenatally (observed/expected lung-to-head ratio [OE-LHR], presence of the liver in the chest) and postnatally (Congenital Diaphragmatic Hernia Study Group [CDHSG] score). Our objective was to identify the risk factors associated with mortality and estimate the risk-adjusted mortality in the prenatal period in the subgroup of patients with isolated left-sided hernia.Population and methods. Retrospective and analytical study of patients born at Hospital Italiano de Buenos Aires between 2011 and 2018. A multivariate analysis was done to assess mortality-associated risk factors. For risk-adjusted mortality in the prenatal period, the ratio between the observed mortality and the mean "expected" mortality based on the OE-LHR was estimated.Results. A total of 53 patients were included. Their median gestational age was 38 weeks, and their mean birth weight was 3054 g. Isolated hernia was observed in 73 % of patients. Overall mortality was 45 %, and higher in patients with associated malformations. In the multivariate analysis, the presence of severe pulmonary hypertension estimated by postnatal echocardiogram was independently associated with mortality (adjusted odds ratio: 6.4, 95 % confidence interval: 1.02-40). The observed overall mortality in patients with isolated left-sided hernia was similar to that expected (ratio: 1.05).Conclusion. Overall mortality was similar to that expected based on the OE-LHR. In our population, severe pulmonary hypertension after birth was a determining factor of mortality

RESUMO

RESUMEN La recurrencia de las hernias diafragmáticas congénitas, luego de reparadas quirúrgicamente, es de baja frecuencia. Se presenta el caso de un paciente masculino de 22 años con hernia diafragmática congénita reparada inicialmente al segundo día de vida, el cual presenta disnea grado 1 y enfermedad por reflujo gastroesofágico. Se evidencia por medio de imagen una hernia diafragmática izquierda, el saco herniario con contenido de bazo, colon, cola de páncreas y glándula suprarrenal izquierda. Se aborda de manera abdominal mediante incisión subcostal izquierda, se reduce el saco herniario, se coloca malla tipo en el defecto diafragmático y se realiza procedimiento de Ladd por la presencia de malrotación intestinal.

ABSTRACT Recurrence of congenital diaphragmatic hernia, after surgical repair, is infrequent. Here, we report the case of a 22-year-old male patient with a history of congenital diaphragmatic disease initally treated with surgery on the second day of life who presented class I dyspnea and gastroesophageal reflux. A left diaphragmatic hernia with a hernia sac containing the spleen, colon, tail of pancreas and left adrenal gland. The patient underwent surgical repair via a left subcostal incision; the hernia sac was reduced, the diaphragmatic defect was repaired with a mesh and the Ladd procedure was performed due to the diagnosis of intestinal malrotation.
