Benefit of video-assisted thoracic surgery in the emergency of a complicated postpartum diaphragmatic hernia / Beneficio de la cirugía torácica video-asistida en la emergencia de una hernia diafragmática posparto complicada

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.

Comparación de recidiva posterior a hernioplastía diafragmática con cierre directo versus colocación de parche / Comparison of recurrence after diaphragmatic hernioplasties with direct closure versus patch placement

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.

Hernia de Morgagni en el adulto / An Adult with Morgagni Hernia

La hernia diafragmática de Morgagni suele presentarse con poca frecuencia en adultos dado su origen congénito. Por este motivo, suele confundirse desde el punto de vista imagenológico con un lipoma mediastinal, como el caso que nos ocupa. Se presenta un caso de hernia diafragmática de Morgagni en adulto, la cual fue intervenida quirúrgicamente por videotoracoscopia con una evolución posoperatoria satisfactoria(AU)

The Morgagni diaphragmatic hernia usually occurs with a low frequent in adults due to its congenital origin. Therefore, it is often mistaken, imaginologically speaking, for a mediastinal lipoma, as in this case of interest. A case is presented of an adult with a Morgagni diaphragmatic hernia, which was surgically intervened by video-assisted thoracoscopy with a satisfactory postoperative evolution(AU)

Herniorrafia diafragmática videoassistida em gato: relato de caso / Videoassisted diaphragmatic hernia repair in a cat: case report

Relata-se um caso de um felino com sinais de dificuldade respiratória havia cerca de 30 dias e emagrecimento progressivo. Ao exame radiográfico torácico e de abdômen, ficou evidenciada perda de definição da linha diafragmática, sendo compatível com hérnia diafragmática. Na laparoscopia, foi observado grande defeito diafragmático, além de estruturas herniadas. Em razão de as vísceras abdominais direcionarem-se ao tórax, dificultando a oclusão do defeito com suturas intracorpóreas, optou-se pela realização de incisão paracostal, procedendo-se à herniorrafia por celiotomia reduzida. A videolaparoscopia permitiu localizar o local herniado e promover a redução dos órgãos envolvidos com mínimo trauma operatório. Logo, mostrou-se como eficaz ferramenta diagnóstica e auxiliar no tratamento de hérnias diafragmáticas crônicas de grande dimensão em gato.(AU)

This is a case report of a cat with signs of respiratory distress for about 30 days and progressive weight loss. The thoracic radiograph and abdomen examination evidencing loss of definition of the diaphragmatic line is compatible with diaphragmatic hernia. In laparoscopy, a large diaphragmatic defect and herniated structures were observed. Since abdominal viscera point towards the chest making occlusion of defective intracorporeal sutures difficult, paracostal incision proceeding to hernia repair by short celiotomy was chosen. Laparoscopy allows for location of herniated place and promotes the reduction of organs involved with minimal surgical trauma. Therefore, it was shown to be an effective diagnostic tool and an aid in the treatment of chronic diaphragmatic hernias of large size in a cat.(AU)

Hernia diafragmática en pediatría / Diaphragmatic hernia in children

The diaphragmatic hernia is a disorder in the development of the diaphragm, causing the passage of the abdominal contents into the thoracic cavity. The main ones are Bochdalek, hiatal and Morgagni hernias. Prenatal ultrasound determines the diagnosis, prognosis and therapy. Lately nuclear magnetic resonance is being used. The surgical procedure consists of the closure of the defect and correcting the intestinal malrotation. The goal of the treatment is to maintain adequate gas exchange and to prevent or minimize hypoplasia and pulmonary hypertension. This article discusses the diagnosis and management of the various forms of diaphragmatic hernia.

La hernia diafragmática (HD) consiste en un trastorno en el desarrollo del músculo diafragmático, produciéndose el paso de contenido abdominal a la cavidad torácica. Las principales son hernia de Bochdalek, Morgagni y hiatal. La ecografía prenatal determina el diagnóstico, pronóstico y terapia, últimamente se está utilizado la resonancia nuclear magnética. La cirugía consiste en cerrar el defecto y corregir la malrotación intestinal, siendo el objetivo del tratamiento mantener un adecuado intercambio gaseoso y evitar o minimizar la hipoplasia y la hipertensión pulmonar. En este artículo se revisa el diagnóstico y manejo de las diferentes modalidades de hernia diafragmática.

Laparoscopic diaphragmatic hernioplasty in a dog / Hernioplastia diafragmática laparoscópica em cão

A diaphragmatic hernia is characterized by the passage of the abdominal viscera into the thoracic cavity, which may be congenital or acquired. Its treatment is achieved by surgical correction. When there is no tissue or in cases of herniation with a chronic disease, the use biological or synthetic implants is recommended. The objective of this study was to report a technique of laparoscopic diaphragmatic hernia repair using bovine pericardium preserved in a canine, using three portal accesses. Due to the large diaphragmatic defect, reduction with the aid of a network of preserved bovine pericardium in formaldehyde 4% was chosen. The mesh was sutured to the transversus abdominus muscle in two layers. The first layer was sutured using simple continuous pattern, and the second one using simple interrupted sutures. The patient collapsed and died 24 hours postoperatively. However, the purposed technique was feasible...

A hérnia diafragmática é caracterizada pela passagem das vísceras abdominais para a cavidade torácica, podendo ser de origem congênita ou adquirida, que exige o tratamento cirúrgico. Quando houver ausência de tecido ou em casos de herniação com evolução crônica, recomenda-se a utilização de implantes biológicos ou sintéticos. O objetivo deste trabalho é relatar a técnica de herniorrafia diafragmática laparoscópica com o uso de pericárdio bovino conservado em um canino, a partir do acesso laparoscópico com três portais. Devido ao grande defeito diafragmático, optou-se pela sua redução com o auxílio de implante de pericárdio bovino conservado em formaldeído a 4%, este fixado a musculatura diafragmática com sutura intracorpórea, utilizando para isso duas camadas de sutura ambas com náilon 0, a primeira contínua simples seguida de pontos isolados simples, em toda extensão da membrana conservada. Apesar do animal vir a óbito nas primeiras 24 horas do pós-operatório, a técnica adotada se mostrou viável...

Traumatic Diaphragmatic Hernia.

Blunt traumatic diaphragmatic ruptures are uncommon yet associated with high mortality. They occur due to blunt or penetrating thoraco-abdominal injury. Diagnosis is often missed, and a high index of suspicion is vital. They may present acutely or delayed as respiratory distress or obstruction. They can be managed through a laparotomy or a thoracotomy and in the present day with minimal access surgery. We report an interesting case of blunt traumatic diaphragmatic hernia in a 48-year-old man presenting after abdomino-thoracic injury due to fall from height. He had herniation of the colon and stomach. Through a left subcostal incision, the herniated organs were reduced, and the diaphragmatic defect closed with prolene suture.

Cirugía mínimamente invasiva en recién nacidos de < 2. 500 g / Minimally invasive surgery in newborns weighting less than 2, 500 g

Newborns (NB) represent a surgical challenge for the surgeon due to their physiological characteristics and reduced surgical spaces. During the last decade, minimally invasive surgery (MIS) has been adopted as a treatment for this group of patients. Objective: To report our experiences of MIS on NB weighing less than 2,500 grams. Patients and Method: A retrospective descriptive study was conducted analyzing the records of newborns weighing less than 2,500 g and subjected to MIS between April, 2009 and 2012. No patients were excluded. Results: 25 newborns participated on this study; among the treated conditions, congenital diaphragmatic hernia (1), Esophageal Atresia (4 complete repairs and 2 fistula ligation), duodenal obstruction (7), Gastroesophageal reflux disease (6 Nissen procedures, 4 including gastrostomy), Laparoscopic gastrostomy (2) Intestinal obstruction (two bowel resections, end to end anastomosis), and Hypertrophic pyloric stenosis (1). The average weight was 1,920 g (1,300-2,490 g) and 10 of the infants were preterm newborns. 3 mm instruments were used, 5 mm optic 30°. Neither intraoperative complications nor conversions were observed. A patient with tracheoesophageal atresia presented a fistula at the site of anastomosis with spontaneous resolution. Conclusions: MIS has revolutionized surgery, resulting in less intestinal adhesions, postoperative pain, shorter hospital stays and better aesthetic results. Due to the availability of smaller size materials, these procedures could be performed safely.

El Recién Nacido (RN) quirúrgico representa un reto para el cirujano, por sus características fisiológicas y espacios quirúrgicos reducidos. Durante la última década se incorporó la cirugía mínimamente invasiva (CMI) en este grupo de pacientes. Objetivo: Reportar nuestra experiencia en CMI en RN < 2.500 g. Pacientes y Método: Estudio descriptivo retrospectivo, se analizaron fichas de RN < 2.500 g sometidos a CMI entre abril de 2009 y abril de 2012. No se excluyeron pacientes. Resultados: Se incluyeron 25 RN. Las patologías resueltas fueron: Hernia diafragmática congénita (1), Atresia Esofágica (4 reparaciones completas, 2 ligaduras de fístula), Obstrucción Duodenal (7), Reflujo Gastro-esofágico (6 operaciones de Nissen; 4 con gastrostomía), gastrostomía laparoscópica (2), Obstrucción Intestinal (2 resecciones intestinales, anastomosis término-terminal), Estenosis Hipertrófica del Píloro (1). Peso promedio: 1.920 gr (1.300-2.490 gr), 10 RN pre-término. Se utilizó instrumental de 3 milímetros (mm), óptica de 5 mm de 30°. No se presentaron complicaciones intra-operatorias, ni conversión. Un paciente con atresia tráqueo-esofágica, presentó una fístula en el sitio de anastomosis con resolución espontánea. Conclusiones: La CMI ha revolucionado la cirugía, manifestándose en disminución de adherencias intestinales, menor dolor postoperatorio, estadías hospitalarias más cortas y mejor resultado estético. Con el desarrollo material de menor tamaño, estos procedimientos se pudieron realizar en forma segura en esta serie.

Transthoracic repair of diaphragmatic hiatus hernia with esophageal shortening where laparoscopic abdominal approach does not give satisfactory results.

A 50 year old female patient presented with history of regurgitation of food, heart burn, dyspepsia. Patient was investigated and presence of large hiatus hernia was confirmed on endoscopy, computed tomogram chest and barium swallow. Patient had severe symptoms even with maximum medical management, therefore surgical intervention was planned. Left posterolateral thoracotomy was done through sixth intercostal space. Mobilization of esophagus, reduction of stomach and Belsey Mark IV 270 degree anterolateral fundoplication was done. Patient was discharged on 7th postoperative day. First follow up was I month after the discharge and patient had significant relief from the preoperative problems.

Oclusión intestinal por hernia de Bochdalek / Intestinal occlusion caused by Bochdalek hernia

La hernia de Bochdalek es un defecto congénito de la región posterolateral del diafragma, usualmente del lado izquierdo, se presenta en 1 de cada 2 000-5 000 nacidos vivos, su diagnóstico en el momento del nacimiento es relativamente fácil, no así cuando este debe realizarse después del período neonatal, pues puede conllevar a evaluaciones erróneas desde el punto de vista clínico y radiológico. La presentación tardía de esta entidad no es frecuente, por lo que nos proponemos dar a conocer un caso de oclusión intestinal por hernia diafragmática de presentación tardía y revisar la literatura al respecto. Se presenta un lactante de 5 meses producto de un tercer embarazo, parto distócico por presentación pelviana, oligoamnios, Apgar 9-9, antecedentes de salud hasta el cuarto mes en que se le introduce leche de chiva y comienza con regurgitaciones bastante frecuentes. Se le realiza diagnóstico a los 5 meses de oclusión intestinal por hernia diafragmática congénita. Se interviene quirúrgicamente sin complicaciones posoperatorias, es dado de alta a los 7 días, y seguido por consulta externa, con evolución satisfactoria. La hernia diafragmática congénita, cuando se presenta después del periodo neonatal, puede diagnosticarse incidentalmente en un estudio radiológico, o por complicaciones secundarias al paso de las vísceras abdominales al tórax

Bochdalek hernia is a congenital defect of the posterolateral region of the diaphragm, usually located on the left side. It appears in one per 2000 to 5000 live births; the diagnosis at birth is relatively easy but after the neonatal period, it can lead to erroneous assessments from the clinical and radiological viewpoints. The late-presenting hernia is not frequent, so we intended to present a case of intestinal occlusion caused by late-presenting diaphragmatic hernia and to make a literature review on this topic. Here is the case of a 5 months-old infant born from a third pregnancy, which was dystotic as a result of pelvic presentation and with oligohydramnios. He had an Apgar score of 9.9 and a history of health problems until his fourth month of life when he began to be fed with goat's milk and it appeared pretty frequent regurgitation. He was diagnosed at 5 months of life with intestinal occlusion due to congenital diaphragmatic hernia. He was operated on, no complications were observed and then he was discharged from the hospital after 7 days and followed-up at outpatient service, with satisfactory recovery. The congenital diaphragmatic hernia that occurs after the neonatal period can be incidentally diagnosed in a radiological study or because of secondary complications when abdominal viscerae passed into the thorax

Hernia diafragmática congénita atascada / Stuck congenital diaphragmatic hernia

La hernia diafragmática congénita constituye uno de los retos pendientes dentro de las enfermedades quirúrgicas del recién nacido. Se presenta un caso muy inusual, en el cual se diagnosticó una hernia diafragmática derecha atascada, con compromiso de gran parte del intestino. Se describen los medios diagnósticos utilizados, el procedimiento quirúrgico realizado y las complicaciones presentadas. La hernia diafragmática congénita atascada es una complicación potencialmente letal, por el amplio compromiso vascular que produce en los órganos abdominales y que conlleva a la necrosis de estos si no se diagnostica precozmente. Por ello, debe ser considerada en el diagnóstico diferencial de la insuficiencia respiratoria en los recién nacidos y lactantes pequeños

Congenital diaphragmatic hernia is one of the pending challenges in dealing with the surgical diseases of the newborn. This was a very unusual case of a right stuck diaphragmatic hernia that affected a large part of the intestine. The used diagnostic means, the surgical procedure and the observed complications were described. Stuck congenital diaphragmatic hernia is a potentially lethal complication because of the wide vascular effect on the abdominal organs, leading to their necrosis if this problem is not early diagnosed. Therefore, it must be taken into account in the differential diagnosis of the respiratory failure in newborns and small infants

Hernia diafragmática complicada con rotura de víscera hueca dentro de la cavidad torácica / Complicated diaphragmatic hernia with hollow viscus rupture in thoracic cavity

Introduction: diaphragmatic hernias (DH) are a rare condition in adult patients. Most of the cases are asymptomatic findings in imaging studies. Rarely do they present as complicated cases. Clinical cases: we report two clinical cases of complicated DH, one of Bochdalek and another with history of a penetrating thoracic trauma two years before, both with hollow viscus rupture in the thoracic cavity.

Introducción: las hernias diafragmáticas (HD) son una patología relativamente poco frecuente en adultos. La gran mayoría son hallazgos asintomáticos en exámenes de imágenes, y en ocasiones debutan con complicaciones de éstas. Casos clínicos: se presentan dos casos clínicos de HD, una de Bochdalek y otra con antecedente de trauma penetrante torácico hace 2 años, ambas complicadas con rotura de víscera hueca en la cavidad torácica.

Transdiaphragmatic intercostal hernia: imaging aspects in three cases / Hernia intercostal transdiafragmatica: aspectos de imagem em tres casos

Transdiaphragmatic intercostal hernia is uncommon and mostly related to blunt or penetrating trauma. We report three similar cases of cough-induced transdiaphragmatic intercostal hernia, highlighting the anatomic findings obtained with different imaging modalities (radiography, ultrasonography, CT, and magnetic resonance) in each of the cases.

Hérnias intercostais transdiafragmáticas são eventos raros e são geralmente relacionadas a traumas abertos ou fechados, com risco de complicações. Relatamos três casos semelhantes, decorrentes de crises de tosse, destacando o aspecto das alterações anatômicas nos exames de imagem obtidos em cada situação (radiografia, ultrassonografia, TC e ressonância magnética).

Oclusión intestinal por hernia diafragmática derecha encarcelada / Intestinal occlusion for incarcerate left diaphragmatic hernia

La hernia de Morgagni es un defecto congénito de la cara anteromedial del diafragma, que se presenta de forma infrecuente en el adulto. En la mayor parte de los casos su diagnóstico es un hallazgo incidental, y por lo general, los pacientes se encuentran asintomáticos. Se diagnostican radiológicamente y posteriormente se indica la cirugía por el riesgo de estrangulación. Se presentó un caso clínico de una paciente de 78 años, con previo diagnóstico de hernia diafragmática derecha mediante técnicas imagenológicas, que comenzó con manifestaciones de cuadro oclusivo. Fue operada de urgencia por vía transabdominal, se hizo la reducción del saco herniario donde se encontraba epiplón, colon transverso y parte del estómago, y se reparó el defecto diafragmático. El propósito de este trabajo fue reportar un caso reciente de oclusión intestinal causada por hernia de Morgagni encarcelada, su diagnóstico y abordaje quirúrgico.

The Morgagni hernia is a congenital defect of the diaphragm anteromedial side, infrequently present in adults. In most of the cases its diagnosis is an incidental finding, and in general the patients are asymptomatic. They are diagnosed radiologically, and once diagnosed the surgery is indicated to avoid the risk of strangulation. We presented the clinical case of a 78-years-old female patient with a previous diagnosis of left diaphragmatic hernia obtained using imaging techniques, who began with manifestations of an occlusive picture. She was immediately operated by transabdominal way, reducing the hernia sac containing mesentery, transversal colon and part of the stomach, and the diaphragmatic defect was repaired. The purpose of this work was reporting a recent case of intestinal occlusion caused by incarcerated Morgagni hernia, its diagnosis and surgical management.

Características clínico epidemiológicas de pacientes con hernia diafragmática congénita. Instituto Nacional de Salud del Niño, 2006 - 2010 / Epidemiological and clinical characteristics of patients with congenital diaphragmatic hernia. National Institute of Child Health, 2006 - 2010

Se realizó un estudio es de tipo observacional, descriptivo, retrospectivo con el objetivo de describir las características clínico epidemiológicas de los pacientes con Hernia Diafragmática Congénita (HDC) atendidos en el Instituto Nacional de Salud del Niño (INSN), en el periodo 2006 - 2010. Se incluyeron a pacientes del INSN con diagnóstico de HDC a los que se les realizó corrección quirúrgica. Fueron excluidos pacientes con diagnóstico de HDC recidiva, procedentes de otros establecimientos de salud, pacientes con hernia del hiato esofágico y pacientes con hernia diafragmática traumática. Resultados: se hallaron 24 pacientes con HDC, de los cuales 29 por ciento fueron neonatos, el 71 por ciento restante tuvo edades entre 2 meses y 15 años. El 58 por ciento de los pacientes fue de sexo masculino y 42 por ciento de sexo femenino. Los signos y síntomas predominantes fueron: disnea (67 por ciento), murmullo vesicular disminuido en hemitórax izquierdo (38 por ciento), presencia de ruidos hidroaéreos en tórax (33 por ciento) y abdomen excavado (21 por ciento).

Oclusão traqueal para fetos com hérnia diafragmática esquerda grave isolada: um estudo experimental controlado não randomizado / Tracheal occlusion for fetuses with severe isolated left-sided diaphragmatic hernia: a nonrandomized controlled experimental study

OBJETIVO: Comparar a sobrevida pós-natal de fetos com hérnia diafragmática congênita esquerda grave isolada, os quais foram submetidos à oclusão traqueal, com a de controles não randomizados contemporâneos. MÉTODOS: Estudo experimental não randomizado e controlado, conduzido de abril de 2007 a setembro de 2011. Fetos portadores de hérnia diafragmática congênita esquerda isolada com herniação hepática e relação pulmão/cabeça <1,0, que foram submetidos à oclusão traqueal (grupo de estudo) ou conduta expectante (controles não randomizados contemporâneos), foram comparados quanto à relação pulmão/cabeça e ao observado/esperado da relação pulmão/cabeça no diagnóstico, à idade gestacional por ocasião do parto e sobrevida neonatal com alta do berçário. A evolução da relação pulmão/cabeça e do observado/esperado da relação pulmão/cabeça depois da oclusão traqueal foi descrita. Testes de Fisher, Mann-Whitney e Wilcoxon foram usados na análise estatística. RESULTADOS: Não houve diferenças significativas entre o grupo de estudo (n=28) e o Controle (n=13) quanto à relação pulmão/cabeça (p=0,7) e ao observado/esperado da relação pulmão/cabeça (p=0,5), no momento do diagnóstico, nem à idade gestacional no parto (p=0,146). A sobrevida com alta do berçário foi maior (p=0,012) no grupo da oclusão traqueal (10/28=35,7 por cento) do que no Grupo Controle (0/13=0,0 por cento). Houve aumento da relação pulmão/cabeça (p<0,001) e do observado/esperado da relação pulmão/cabeça (p<0,001) entre o momento do diagnóstico da hérnia diafragmática congênita [relação pulmão/cabeça: 0,8 (0,4-0,9); observado/esperado da relação pulmão/cabeça: 27,0 (15,3-45,0)] e um dia antes da retirada do balão traqueal [relação pulmão/cabeça: 1,2 (0,5-1,8); observado/esperado da relação pulmão/cabeça: 40,0 (17,5-60,0)]. CONCLUSÕES: Houve melhora significativa na sobrevida pós-natal com alta do berçário de fetos com hérnia diafragmática congênita esquerda isolada grave, que foram submetidos à oclusão traqueal em relação a controles não randomizados contemporâneos.

PURPOSE: To compare postnatal survival to hospital discharge of fetuses with severe isolated left-sided congenital diaphragmatic hernia, who underwent tracheal occlusion, with that of nonrandomized contemporaneous controls. METHODS: Experimental nonrandomized controlled study, performed from April 2007 to September 2011. Fetuses with severe isolated left-sided congenital diaphragmatic hernia with liver herniation into the chest and lung area-to-head circumference ratio <1.0, who underwent tracheal occlusion (study group) or expectant management (non-randomized contemporaneous controls), were compared in terms of lung area-to-head circumference ratio and observed/expected lung area-to-head circumference ratio (observed/expected lung area-to-head circumference ratio) at the time of diagnosis, gestational age at birth, and survival to hospital discharge. Modifications in lung area-to-head circumference ratio and o/e lung area-to-head circumference ratio after tracheal occlusion were also analyzed. Fisher's exact test, Mann-Whitney's or Wilcoxon's tests were used for the comparisons. RESULTS: There were no significant differences between the Study Group (TO=28) and Controls (n=13) in terms of the lung area-to-head circumference ratio (p=0.709) and the observed/expected lung area-to-head circumference ratio (p=0.5) at the time of diagnosis and gestational age at birth (p=0.146). The survival to hospital discharge was higher (p=0.012) in the tracheal occlusion group (10/28=35.7 percent) than in controls (0/13=0.0 percent). There was a significant increase in lung area-to-head circumference ratio (p<0.001) and observed/expected lung area-to-head circumference ratio (p<0.001) between the diagnosis of the congenital diaphragmatic hernia [lung area-to-head circumference ratio: 0.80 (0.40-0.94); observed/expected lung area-to-head circumference ratio: 27.0 (15.3-45.0)], and the day before retrieval of the balloon [lung area-to-head circumference ratio: 1.2 (0.50-1.80); observed/expected lung area-to-head circumference ratio: 40.0 (17.5-60.0)]. CONCLUSIONS: There was a significant improvement in the survival rate to hospital discharge of fetuses with severe isolated left-sided congenital diaphragmatic hernia, who underwent tracheal occlusion in comparison to nonrandomized contemporaneous controls.

Rare presentation of spontaneous acquired diaphragmatic hernia.

Spontaneous acquired diaphragmatic hernia without any apparent history of trauma is a very rare condition and is very difficult to diagnose. We present a case of a 21-year-old male who presented with abdominal pain for one month and four episodes of vomiting for one day. Clinical suspicion, chest radiography with nasogastric tube in situ and computed tomography (CT) confirmed the diagnosis. The diaphragmatic defect was repaired surgically. The patient had an uneventful post-operative recovery.

Challenges in the management of early versus late presenting congenital diaphragmatic hernia in a poor resource setting

Background: Despite the advances in management; congenital diaphragmatic hernia (CDH) has continued to pose a significant challenge to paediatric surgeons. This is amplified in a setting like ours where there is a dearth of facilities to cope with the problem of CDH. This study was undertaken to highlight the peculiarities of the management of CDH in a poor resource setting. Methods: All confirmed cases of CDH were prospectively documented from 2003 till date. Results: Seven children were treated from 2003 till date. The diaphragmatic defect was on the left side in six (83.8) and on the right side in one (17.7). All the patients had primary closure of the defect without patch via an abdominal approach. The three patients presenting at birth died while the remaining four patients survived. Conclusion: With inadequate neonatal intensive care facilities; the severe early presenting CDH has a dismal prognosis. In contrast; the late presenting CDH poses more diagnostic challenges; but once identified and appropriate treatment instituted; it has an excellent prognosis. We recommend that physicians should include CDH in the differential diagnosis of patients with birth asphyxia and in patients with chronic respiratory symptoms with failure to thrive
