Hernia diafragmática traumática derecha en paciente geriátrico. Reporte de un caso infrecuente / Traumatic right diaphragmatic hernia in an elderly patient. A rare case report

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)

Hernia diafragmática derecha postraumática de presentación tardía. Un caso infrecuente / Post-traumatic right diaphragmatic hernia of late presentation. A rare case

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

Natural evolution of perforating wounds of 30% extension of the left diaphragm and the anatomopathological characteristics of its healing. Experimental Study / Evolução natural das feridas perfurocortantes de 30% de extensão do diafragma esquerdo e das características anatomopatológicas de sua cicatrização. Estudo Experimental

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.

Manejo laparoscópico de hernia diafragmática traumática: reporte de un caso / Laparoscopic management of traumatic diaphragmatic hernia: a case report

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.

Herida toracoabdominal izquierda como causa de hernia diafragmática. Presentación de tres casos / Left thoraco-abdominal wound as a cause of diaphragmatic hernia. Presentation of three cases

RESUMEN Las lesiones por arma blanca en la región toracoabdominal tienen la posibilidad potencial de dañar dos cavidades anatómicas: tórax y abdomen, con la subsiguiente lesión del músculo diafragma y la producción de una hernia de contenido visceral, asociada o no a lesión visceral. En caso de que esta entidad clínica sea pasada por alto, existe una alta probabilidad de complicaciones que ponen en riesgo la vida; por tanto, realizar un manejo adecuado constituye un reto para el cirujano general, que precisa de un alto índice de sospecha para formular el diagnóstico. Se presentan tres casos de víctimas de agresión con arma perforo-cortante en región toracoabdominal izquierda, atendidos en instalaciones donde se disponía de limitados recursos diagnósticos. Se exponen datos clínicos, pruebas de apoyo al diagnóstico, procedimiento quirúrgico, curso posoperatorio y evolución. El abordaje quirúrgico abdominal es la regla de oro para reparar el diafragma lesionado, y la pleurostomía mínima es eficaz cuando existe compromiso torácico.

ABSTRACT Injuries caused by white arms in the thoraco-abdominal region have the potential to damage both anatomical cavities: thorax and abdomen, with the subsequent injury of the diaphragm muscle and the production of a visceral hernia, associated or not with visceral injury. In case this clinical entity is overlooked, there is a high probability of life-threatening complications; therefore, adequate management is a challenge for the general surgeon, who needs a high index of suspicion to formulate the diagnosis. Three cases of victims of assault with a perforating-cutting weapon in the left thoraco-abdominal region are presented, attended in facilities where limited diagnostic resources were available. Clinical data, diagnostic support tests, surgical procedure, postoperative course and progress are explained. The abdominal surgical approach is the gold rule for repairing the injured diaphragm, and the minimal thoracostomy is effective when there is thoracic involvement.

Alternativas quirúrgicas en hernias y eventraciones diafragmáticas crónicas / Surgical alternatives for chronic diaphragmatic hernias and eventrations

Introducción: las eventraciones y las hernias diafragmáticas crónicas son dos afecciones que en ocasiones se confunden; tienen una frecuencia relativamente baja y su estrategia quirúrgica varía. Objetivo: mostrar la experiencia del Hospital Universitario Clínico Quirúrgico Comandante Manuel Fajardo en la atención de enfermos con hernias y eventraciones diafragmáticas. Métodos: se presentan 11 pacientes atendidos desde 1998 hasta 2015 por afecciones del diafragma como eventraciones y hernias diafragmáticas crónicas. Del total, 7 fueron operadas con anillos de hasta 10 cm y dos con más de 10 cm. Resultados: se operaron 9 pacientes con hernias diafragmáticas y 2 con eventraciones. Ocho hernias fueron del lado izquierdo y una derecha. En 8 de las hernias el contenido era multivisceral. La hernia derecha tenía un anillo de más de 10 cm y con el hígado en su contenido. Cinco fueron reparadas mediante superposición de colgajos y en cuatro se necesitó una malla protésica. Las eventraciones se presentaron en dos mujeres, ambas parciales, una derecha y otra izquierda, tratadas con plicatura del hemidiafragma en dos planos. Conclusiones: las hernias y las eventraciones diafragmáticas son entidades parecidas con particularidades y terapéutica diferentes. En las eventraciones, la plicatura del diafragma es la técnica de elección, por vía abierta o de preferencia por toracoscopia. En las hernias diafragmáticas, la reparación depende del tamaño del anillo, hasta 10 cm se prefiere la reparación con superposición de colgajos y en defectos mayores el uso de mallas protésicas, preferentemente por una toracotomía(AU)

Introduction: Chronic diaphragmatic hernias and eventrations are two conditions sometimes mistaken for each other. They have a relatively low frequency and their surgical strategy varies. Objective: To show the experience at Comandante Manuel Fajardo Clinical Surgical University Hospital in the caring for patients with diaphragmatic eventrations and hernias. Methods: 11 patients attended from 1998 to 2015 were presented for diaphragmatic conditions, such as hernias and chronic diaphragmatic eventrations. Of the total, 7 were operated with rings of up to 10 cm. Two were operated for rings of more than 10 cm. Results: 9 patients with diaphragmatic hernias and 2 with incisional hernias were operated. Eight hernias were on the left side. One hernia was on the right side. In 8 of the hernias, the content was multivisceral. The right hernia had a ring of more than 10 cm, and had the liver in its content. Five hernias were repaired by flaps. Four hernias required a prosthetic mesh. The eventrations were presented in two women, both partial: one was on the right and the other was on the left, and both were treated with plication of the hemidiaphragm in two planes. Conclusions: Diaphragmatic hernias and eventrations are similar entities with different characteristics and therapeutics. In eventrations, the plication of the diaphragm is the technique of choice, either openly or preferably by thoracoscopy. In diaphragmatic hernias, repair depends on the size of the ring, up to 10 cm, flap repair is preferred, and in larger defects, it is the use of prosthetic meshes, preferably by thoracotomy(AU)

Hernia diafragmática aguda en un adolescente / Acute diaphragmatic hernia in an adolescent

Se presenta el caso clínico de un paciente de 13 años de edad, quien ingresó en el Servicio de Cirugía del Hospital Básico de Latacunga, Ecuador, tras haber sido atropellado por un automóvil que le produjo traumatismos torácico y abdominal cerrados. Los estudios radiológicos confirmaron el diagnóstico de hernia diafragmática traumática izquierda. Durante la cirugía se encontró un defecto de 10 cm en el diafragma izquierdo, con el estómago, bazo y colon herniados en el tórax, para lo cual se efectuó reducción y frenorrafia. Dicho paciente evolucionó satisfactoriamente y egresó al quinto día. Se realizó seguimiento durante 6 meses y no presentó complicaciones.

The case report of a 13 year-old patient is presented who was admitted in the Surgery Service of the Basic Hospital from Latacunga, Ecuador, after being runned over by an automobile that produced him closed thoracic and abdominal traumatisms. The radiological studies confirmed the diagnosis of left traumatic diaphragmatic hernia. During surgery a defect of 10 cm was found in the left diaphragm, with stomach, spleen and colon herniated in the thorax, for which reduction and frenorrafia were carried out. This patient had a satisfactory clinical course and was discharged on the fifth day. Follow-up was carried out during 6 months and there were no complications.

Hérnia diafragmática direita associada à hepatotórax assintomático com correção de cirurgia precoce / Right diaphragmatic hernia associated to asymptomatic hepatotorax with early surgical correction

A ruptura diafragmática decorrente de lesão traumática é uma entidade rara, secundária ao trauma fechado ou penetrante. O diagnóstico é difícil, o que pode fazer com que o tratamento cirúrgico seja retardado, acarretando um aumento da morbimortalidade. Os autores relatam o caso de paciente de 39 anos, do sexo feminino, vítima de trauma com alto impacto devido a atropelamento. Após 13 dias de internamento, radiografia de tórax permaneceu com obliteração do seio costofrênico e velamento do terço inferior do hemitórax direito. Tomografia computadorizada de tórax evidenciou grande parte do fígado em posição intratorácica, sugerindo a possibilidade de ruptura torácica e hepatotórax. O tratamento foi realizado por meio de uma toracotomia anterolateral direita com rafia do defeito diafragmático e redução do saco herniário. Sendo assim, apesar de raro, o hepatotórax é uma entidade que deve sempre ser lembrada em pacientes vítimas de traumas torácicos de alta intensidade.

The diaphragmatic rupture due to traumatic injury is a very rare entity that may be due to blunt or penetrating trauma. Diagnosis is difficult and therefore surgical treatment may be delayed, resulting in increased morbidity and mortality. The authors report the case of a 39-year-old patient, female, who was victim of a high-impact trauma due to trampling. Standard chest X-ray did not showed positive evolution after 13 days of hospitalization, with costophrenic angle obliteration and opacification of the lower third of the right hemithorax. It asked then a chest CT scan that showed much of the liver in intratoracic position. The treatment was carried out successfully by a right anterolateral thoracotomy with suture and correction of diaphragmatic hernia. Thus, although rare, hepatotorax is an entity that should always be remembered in trauma patients with high impact.

Analysis of natural history of the diaphragmatic injury on the right in mice / Análise da evolução natural dos ferimentos diafragmáticos à direita em ratos

Objective: to evaluate natural evolution of right diaphragmatic injury after the surgical removal of a portion from hemi diaphragm. Methods: the animals were submitted to a surgical removal of portion from right hemi diaphragm by median laparotomy. The sample consists of 42 animals being 2 animals from pilot project and 40 operated animals. And the variables of the study were herniation, liver protection, healing, persistent diaphragm injury, evaluation of 16 channels tomography and the variables "heart rate" and "weight". Results: we analyzed 40 mice, we had two post-operative deaths; we had 17 animals in this group suffered from herniation (42.5%) and 23 animals didn't suffer from herniation (57.5%). Analyzing the tomography as image method in the evaluation of diaphragmatic hernia, we had as a method with good sensitivity (78.6%), good specificity (90.9%), and good accuracy (86.1%) when compared to necropsy. Conclusion: there was a predominance of healing of right hemi diaphragm, the size of initial injury didn't have influence on occurrence of the liver protection or hernia in mice.

Objetivo: avaliar a evolução natural do ferimento diafragmático à direita após a retirada cirúrgica de uma porção do hemidiafragma. Métodos: os animais foram submetidos à ressecção de uma porção do hemidiafragma à direita através da laparotomia mediana. Foram operados 40 ratos. As variáveis analisadas foram: herniação, proteção hepática, cicatrização, lesão persistente do diafragma, avaliação da tomografia computadorizada, frequência cardíaca e peso. Resultados: foram analisados 40 ratos. Houve duas mortes no pós-operatório. Dezessete animais tiveram herniação (42,5%) e 23 (57,5%), não. Analisando emprego da tomografia computadorizada na avaliação da hérnia diafragmática, tivemos um método com boa sensibilidade (78,6%), boa especificidade (90,9%) e boa acurácia (86,1%) quando comparados com a necrópsia. Conclusão: houve predomínio de cicatrização do hemidiafragma à direita e o tamanho da lesão inicial não influenciou na ocorrência de proteção hepática ou hérnia em ratos.

Hernia pulmonar espontánea secundaria a acceso de tos: reparación por técnica asistida por video / Spontaneous lung hernia secondary to coughing fit: repair by video assisted technique

La hernia pulmonar es la protrusión del tejido pulmonar a través de una de las estructuras que lo contienen. Generalmente, son secundarias a traumatismos o a un procedimiento quirúrgico; con menos frecuencia, pueden ser espontáneas posteriores a accesos de tos. El diagnóstico se hace por el cuadro clínico y debe confirmarse con radiografía o tomografía, con las cuales se puede ver la protrusión del tejido pulmonar a través de los espacios intercostales. Pueden tratarse de manera conservadora si son asintomáticas, pero el tratamiento más común es el quirúrgico, con técnica abierta o asistida por video. Se presenta una revisión bibliográfica y el reporte de un caso manejado con técnica asistida por video.

Lung hernia is the protrusion of lung tissue through one of its bounding structures. Usually it develops as the result of thoracic trauma or after a surgical procedure; less frequently it can be spontaneous after a coughing fit. Diagnosis is made on the basis of the clinical findings and should be confirmed by X-ray imaging or computed tomography, which evidence the protrusion of the lung through the intercostal spaces. Treatment of lung hernia may be conservative when the patient is asymptomatic, but surgical intervention is most commonly performed, which can be by the open technique or by the video assisted technique. We present a literature review and report a case that was managed by the video assisted surgical technique.

Hernia diafragmática traumática. Presentación de un caso / Traumatic Diaphragmatic Hernia. A Case Report

El trauma diafragmático se produce de forma secundaria tras lesiones penetrantes y trauma cerrado del abdomen y tórax. La hernia diafragmática traumática representa una entidad poco frecuente en la clínica. Cuando se presenta constituye un verdadero reto diagnóstico para el internista, cirujano y el radiólogo. Requiere de un alto índice de sospecha y el uso adecuado de las imágenes diagnósticas. El tratamiento siempre es quirúrgico. Por tales razones se presenta el caso de un paciente que fue operado debido a una herida por arma blanca en el tórax y que con posterioridad se le diagnosticó una hernia diafragmática traumática en el lado izquierdo del torax. Volvió a ser operado y la evolución posquirúrgica resultó satisfactoria.

Diaphragmatic trauma is secondary to penetrating injuries and blunt abdominal and thoracic trauma. Traumatic diaphragmatic hernia is an uncommon entity. Its diagnosis poses a real challenge to internists, surgeons and radiologists since it requires a high level of suspicion and appropriate use of diagnostic imaging. Surgical treatment is always needed. For these reasons, we present the case of a patient operated on due to a stab wound to the chest who was subsequently diagnosed with a traumatic diaphragmatic hernia on the left side of the chest. He underwent surgery again and had a successful postoperative recovery.

Hernia diafragmática traumática en un niño / Diaphragmatic traumatic hernia in the little boy

La hernia diafragmática traumática es una afección poco frecuente sobre todo en edades pediátricas. El objetivo de este trabajo es reportar un caso de hernia diafragmática secundaria a un trauma toracoabdominal cerrado. Se presenta el caso de un paciente de 12 años, masculino ingresado en el Servicio de Cirugía Pediátrica de la Provincia de Santiago de Cuba, por haber sufrido un accidente en el hogar (caída de una pared de ladrillos sobre su cuerpo), que produjo traumatismos a nivel craneal, torácico y lumbar. Los estudios radiológicos confirmaron el diagnóstico de hernia diafragmática traumática izquierda. En el acto quirúrgico se comprueba defecto del diafragma izquierdo de aproximadamente 15 cm, con hernia de estómago, bazo y colon. Se realizó reducción y frenorrafia con puntos de colchonero usando poliéster 0, más pleurostomía mínima baja izquierda. El paciente evolucionó satisfactoriamente y egresó a los 10 días para seguimiento en la consulta externa durante 6 meses hasta el alta definitiva(AU)

Traumatic diaphragmatic hernia is a rare illness at pediatric ages. The objective of this paper was to report a case of diaphragmatic hernia secondary to closed thoracoabdominal trauma. This patient is a 12 years-old boy admitted to the pediatric surgery service of Santiago de Cuba province because of an accident at home (a brick wall fell down upon his body) that caused him cranial, thoracic and lumbar traumas. The radiological studies confirmed the diagnosis of traumatic diaphragmatic hernia on the left side. During the surgical act, there was observed an almost 15cm left diaphragm defect with hernias in stomach, spleen and colon. Reduction and phrenorraphy were performed using mattress sewing stitch type, polyester 0 plus left low minimal pleurostomy. The progression of the patient was satisfactory and was discharged from hospital ten days after surgery to be followed up in the outpatient service for 6 months until his complete recovery(AU)

Hernia diafragmática traumática derecha / Right traumatic diaphragmatic hernia

Paciente masculino, de 47 años de edad que sufrió un accidente automovilístico en el año 1991, con fractura de columna lumbar , que dejó como secuela una paraparesia flácida postraumática con nivel neurológico de lesión del segmento L5, con disminución de la fuerza muscular y de la sensibilidad en las extremidades inferiores. Se le hizo inmovilización con yeso durante 6 meses y fue intervenido quirúrgicamente en ese propio año. Se le realizó fijación y osteosíntesis con material metálico. Se rehabilitó durante varios anos alcanzando buen fortalecimiento muscular y en noviembre de 2008, en horas de la noche, comienza con dolor intenso a nivel de hipocondrio y hemitórax derecho, que se incrementa con el decúbito supino y mejora con el decúbito lateral izquierdo y con disnea moderada. Al examen físico del tórax, se constató aumento de la matidez del tercio inferior del hemitórax derecho y se auscultaron ruidos hidroaéreos a este nivel. Se realizó radiografía (Rx) de tórax vista posteroanterior(PA), donde se constató elevación del hemidiafragma derecho e imagen compatible con presencia de asas intestinales en el tercio inferior de este hemitórax. Se diagnosticó una hernia diafragmática traumática derecha , que es una enfermedad poco frecuente debido al efecto amortiguador del hígado. Se realizó tratamiento médico inicialmente y una hora después , cesa el dolor. Se redujo la hernia de manera espontánea, lo que se corroboró en el Rx de tórax ( vista PA) evolutivo. Posteriormente fue intervenido quirúrgicamente de forma electiva y el resultado fue favorable(AU)

A 47 years-old male patient, who was injured in a car accident in 1991 and suffered lumbar column fracture that left as a sequel a postraumatic flaccid paraparesia with neurological lesion of L5 segment, reduction of muscle strength and sensitivity in lower limbs. He had plaster for 6 months and was surgically treated in that year. He underwent fixation and osteosynthesis with metal material. During several years, he went to rehabilitation program and finally achieved good muscle strengthening. In November 2008, he began feeling intense pain at hypochondrium and right hemithorax at night and also moderate dyspnea. On the physical exam, it was confirmed that there was increase of lower third of right hemithorax and hydroaerial noises were heard. Chest x-ray using posteroanterior view was performed, which revealed increase of right hemidiaphragm and images compatible with intestinal loop in the lower third of this hemithorax. Right traumatic diaphragmatic hernia was diagnosed. This is an infrequent disease due to the shock-absorbing effect of the liver. He was medically treated and one hour later, the pain ceased. Hernia was reduced spontaneously, which was confirmed in the posterior chest x-ray. He was further operated on electively and the final result was favorable(AU)

Presentación tardía de hernia diafragmática traumática con necrosis gástrica: revisión de la literatura científica / Delayed presentation of diaphragmatic hernia with gastric necrosis: literature review

La hernia diafragmática complicada de presentación tardía constituye una urgencia quirúrgica debido a la isquemia y eventual necrosis y gangrena de los órganos herniados. Los órganos o estructuras que se encuentran con mayor riesgo de sufrir complicaciones por la hernia son el colon, el estómago, el bazo, el epiplón mayor y los intestinos. La necrosis y gangrena del estómago se deben a su estrangulamiento dentro de la hernia, lo que constituye una complicación grave y potencialmente mortal. El presente artículo resume brevemente la literatura científica relevante sobre el diagnóstico clínico y radiológico, y el tratamiento de la necrosis gástrica como complicación de la hernia diafragmática de presentación tardía.

Complicated diaphragmatic hernia with delayed presentation constitutes a surgical emergency due to ischemia and eventual necrosis and gangrene of the herniated organs. The organs or structures at greater risk of complications are colon, stomach, spleen, greater omentum, and small bowel. Gastric necrosis and gangrene are secondary to the twisting and strangulation of the stomach inside the hernia sac, constituting a severe and potentially lethal complication. This article reviews and briefly resumes the current relevant literature on the clinical and radiological diagnosis and the treatment of gastric necrosis as complication of diaphragmatic hernia with delayed presentation.

Exame radiográfico convencional do tórax no diagnóstico de hérnia diafragmática pós-traumática / Plain chest radiographs for the diagnosis of post-traumatic diaphragmatic hernia

OBJETIVO: Descrever as alterações do exame radiográfico de tórax em pacientes com diagnóstico de hérnia diafragmática pós-traumática (HDPT) confirmado no intraoperatório. MÉTODOS: No período entre janeiro de 1990 e agosto de 2008 foram tratados 45 pacientes com HDPT. Foram analisados dados demográficos, mecanismo de trauma, alterações na radiografia convencional de tórax (Rtx), extensão e localização da lesão do diafragma e órgãos herniados. Foram descritos os achados radiográficos mais frequentes identificados por assistentes da cirurgia e da radiologia. RESULTADOS: A Rtx foi realizada em 32 pacientes, com predomínio do sexo masculino (27 casos - 84,4%) e a média das idades foi 34 anos. O mecanismo de trauma mais frequente foi o contuso (25 casos - 78,1%). O exame radiográfico de tórax apresentava alterações sugestivas de HDPT em 26 casos (81,3%). Na laparatomia exploradora constatou-se HDPT à esquerda em 28 casos (87,5%) e à direita em 4 (12,5%). O órgão herniado mais frequente foi o estômago. CONCLUSÃO: O estudo mostrou que o Rtx é muito útil na pesquisa inicial no diagnóstico de HDPT. A dificuldade é que as lesões de diafragma, principalmente após trauma penetrante, podem passar inicialmente despercebidas, sem alterações nesse método de imagem, tornando o diagnóstico difícil.

OBJECTIVE: To describe changes in the radiographic examination of the chest in patients with post-traumatic diaphragmatic hernia (PTDH) confirmed intra-operatively. METHODS: Between January 1990 and August 2008 45 patients with PTDH were treated. We analyzed demographic data, cause of injury, changes in chest radiography (CXR), extent and location of the diaphragmatic lesion and herniated organs. We described the radiographic findings most frequently identified by surgeons and radiologists. RESULTS: CXR was performed on 32 patients, predominantly male (27 cases, 84.4%) and the mean age was 34 years. The most common cause of injury was blunt trauma (25 cases, 78.1%). Radiographic examination of the chest showed changes suggestive of PTDH in 26 cases (81.3%). During exploratory laparotomy, left PTDH was found in 28 cases (87.5%) and right in four (12.5%). The most frequently herniated organ was the stomach. CONCLUSION: The study showed that CXR is very useful in the initial diagnostic approach to PTDH. The difficulty is that diaphragmatic injuries, particularly after penetrating trauma, may initially go unnoticed, and without changes in the CXR images, diagnosis is made difficult.

Hérnia diafragmática à direita por trauma contuso: uma revisão bibliográfica / Right diaphragmatic hernia due to blunt trauma: a literature review

As hérnias diafragmáticas são decorrentes principalmente de traumas contusos e são mais comuns à esquerda. Essa menor frequência à direita é explicada pela contenção e proteção do fígado ao hemidiafragma homolateral. Entretanto, apesar de as lesões à esquerda serem mais frequentes, aquelas situadas à direita associam-se a lesões mais graves e resultam em mais instabilidade hemodinâmica, o que gera elevada mortalidade no momento do trauma. Além disso, a hérnia diafragmática direita, pode permanecer assintomática por longo tempo, favorecendo a aparecimento de complicações como isquemia e ruptura das vísceras herniadas dentro do tórax. Assim é fundamental um diagnóstico precoce, a fim de se realizar o tratamento cirúrgico, uma vez que o diafragma não cicatriza espontaneamente. (AU)

The diaphragmatic hernias are mainly due to blunt trauma and are more common on the left. This lower frequency on the right side is explained by liver protection of the ipsilateral hemidiaphragm. However, despite the injuries are more frequent on the left, those situated on the right are associated with more severe injuries and result in more hemodynamic instability, which leads to high mortality at the time of trauma. Furthermore, the right diaphragmatic hernia can remain asymptomatic for long time, favoring the onset of complications such as ischemia and rupture of the herniated organs inside the chest. Therefore early diagnosis is fundamental in order to perform surgical treatment, since the diaphragm does not heal spontaneously. (AU)

Hernia diafragmática secundaria a trauma abdominal cerrado / Diaphragmatic hernia secondary to blunt trauma of the abdomen

La hernia diafragmática traumática (HDT) es una complicación poco común en el trauma abdominal cerrado y puede no ser diagnosticada a menos de que se tenga un alto índice de sospecha. El mecanismo fisiopatológico consiste en un impacto de alta energía con aceleración y desaceleración que condiciona incremento súbito de la presión intraabdominal. El hemidiafragma izquierdo es afectado más comúnmente. El diagnóstico temprano y oportuno es fundamental debido a la elevada incidencia con la que se asocia a lesión a otros órganos y complicaciones. El objetivo de este artículo es presentar el caso de un paciente de 62 años que desarrolló hernia diafragmática secundaria a trauma abdominal cerrado y revisar la literatura relacionada a esta entidad.
