A rare clinical entity of asymptomatic adult bochdalek hernia

Bochdalek hernia (BH) is the commonest congenital diaphragmatic hernia, caused by the failure of the posterolateral diaphragmatic foramina to fuse properly. It is extremely rare in adults and accounts for 5-10%. Presenting a case of 48 years female with complaints of dry cough and left chest pain for 1 week. Diminished breath sounds and abnormal gurgling sounds heard on auscultation of left chest wall. X-ray chest showed elevated left hemi diaphragm and gastric bubble. Computed tomography (CT) chest revealed left diaphragmatic hernia with splenic flexure, transverse colon, mesocolon, spleen and upper pole of left kidney as content and atelectasis of left lung lower lobe. Patient underwent laparoscopic repair of hernia with mesh plasty. Intraoperatively, the contents were reduced into the abdominal cavity and left lung expansion noted. The defect of size 6×10 cm in the left diaphragm was sutured and composite mesh placed. Post-operative chest x-ray showed expanded left lung. On follow up of patient after 2 weeks and 1 month, patient was asymptomatic. BH in adults is an uncommon. The contents can be reduced via thoracic or abdominal approach, with abdominal approach having easier access. With the advent of minimal access techniques, delineating clear anatomy, more working space, early recovery, and early return to home and work is possible. Thus, laparoscopic repair of adult diaphragmatic hernia is a safe and effective modality of surgical treatment.

Hernia de Bochdalek en adulto: una entidad extremadamente infrecuente. Reporte de caso / Bochdalek hernia in adult: an extremely infrequent entity

Resumen Introducción: La hernia de Bochdalek es el tipo de hernia diafragmática congénita más frecuente. Existen menos de 200 reportes en adultos, lo cual representa el 5% de la literatura médica. Por lo que su diagnóstico es excepcional. Caso clínico: Mujer de 23 años de edad, ingresó referida de su unidad de salud con diagnóstico de neumotórax espontáneo tras presentar dolor en el hemitórax izquierdo y disnea 24 horas posteriores a trabajo de parto. En el servicio de urgencias se colocó sonda endopleural; sin embargo, al no obtener reexpansión pulmonar, se solicitó TAC simple toracoabdominal e interconsulta con los servicios de radiología y cirugía. Se realizó diagnóstico de hernia de Bochdalek incarcerada y laparotomía urgente con cierre primario del defecto herniario. Cursó con adecuada evolución y fue egresada al cuarto día postoperatorio. Discusión: El diagnóstico de hernia de Bochdalek se asocia a errores diagnósticos hasta en 38% de los casos, dada su baja incidencia y variedad de presentación clínica. En este caso se realizó un diagnóstico inicial de neumotórax con colocación de sonda endopleural, lo cual pudo haber ocasionado graves consecuencias. Conclusión: El diagnóstico de hernia de Bochdalek representa un reto ya que el retraso del manejo se asocia a riesgo elevado de complicaciones.

Abstract Introduction: The Bochdalek hernia is the most common congenital diaphragmatic defect. There are less than 200 cases reported in adults, which represent about 5% of the cases in medical literature; therefore, its diagnosis is hard to make. Clinical case: A 23-year-old female patient who was referred from her medical institution with a diagnosis of spontaneous pneumothorax after suffering from left hemithorax pain and dyspnea 24 hours after undergoing labor. At the emergency room, an endopleural tube was placed, but since there was no pulmonary re-expansion, an unenhanced CT scan was performed and a medical petition was requested to the radiology and surgery department. A diagnosis of incarcerated Bochdalek hernia was made and the patient underwent an emergency laparotomy with primary closure. She recovered successfully and was discharged from hospital on the fourth postoperative day. Discussion: Bochdalek hernia is misdiagnosed in about 38% of the cases because of its low incidence and the different types of clinical presentations. In this case, the main diagnosis was initially a spontaneous pneumothorax with endopleural seal placement, which could have caused several complications. Conclusion: The Bochdalek hernia represents a diagnostic challenge because delaying its management is associated with high-risk complications.

Concomitant diaphragmatic hernia repair with coronary artery bypass grafting surgery

Congenital Bochdalek diaphragmatic hernia (DH) is often diagnosed incidentally in adulthood. It is recommended that all cases of DH be repaired immediately at diagnosis since acute presentation after the complications have already developed has higher morbidity and mortality. A 47-year-old male presented with Grade III angina and dyspnea. A routine chest radiograph revealed bowel shadows in the right thorax, and subsequent computerized tomography (CT) scan confirmed the same. Coronary angiogram revealed coronary artery disease which needed surgery. Off-pump coronary artery bypass grafting followed by DH repair under one-lung ventilation.

rare case of Bochdalek diaphragmatic hernia with concomitant partial situs inversus.

Congenital diaphragmatic hernias clinically presenting in adulthood are exceedingly rare lesions, mainly left-sided defect (Bochdalek). Bochdalek hernias most commonly manifest during the patient’s first few weeks of life. Diagnosis beyond the first 8 weeks of life is estimated to represent 5-25% of all Bochdalek hernias. Here we have a 32 year old female patient who presented with 10x10 cm diaphragmatic hernia with dextrocardia who was asymptomatic for years.

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

An Adult Right-sided Bochdalek Hernia Accompanied with Hepatic Hypoplasia and Inguinal Hernia

We herein report a very rare case of adult right-sided Bochdalek hernia accompanied with hepatic hypoplasia and inguinal hernia. A 29-year-old man was admitted with right-sided pneumothorax. A computed tomography was performed and revealed large right sided Bochdalek hernia with hepatic hypoplasia. Under thoracolaparotomy, the defect was closed with Gore-Tex soft tissue patch. After the operation, left-sided inguinal hernia was found. However, it turned out that it had been present during infancy and spontaneously resolved during adolescence. This is the first report of right-sided Bochdalek hernia with hepatic hypoplasia and inguinal hernia in an adult.

Clinical Study of Congenital Diaphragmatic Diseases in Neonates and Infants

Congenital diaphragmatic disease is one of the common major congenital anomalies, and its mortality remained still high despite recent medical advances. The aim of this study is to examine the clinical characteristics of congenital diaphragmatic diseases. A total of 39 patients with congenital diaphragmatic disease that underwent surgery from January, 1997 to December, 2009 at Pusan National University Hospital were included in this study. Medical records were retrospectively reviewed. The male to female ratio was 30:9. Six out of 39 cases died (NS) before surgery, 17 patients had Bochdalek's hernia (BH), 11 patients hiatus hernia (HH), 4 diaphragmatic eventration (DE), and 1 Morgagni hernia (MH). There were no differences in mean birth weight and mean gestational age. NS (83.3%). BH (35.3%) was diagnosed more frequently than other diseases in the prenatal period. Three patients (17.6%) of BH expired due to pulmonary hypoplasia and 1 patient had co-existing congenital heart disease. BH was diagnosed more frequently in the prenatal stage and had a higher motality rate than other conditions. Therefore, BH needs to be concentrated more than other anomalies.

A Rare Case of Incarcerated Bochdalek Diaphragmatic Hernia in a Pregnant Lady

The occurrence of congenital diaphragmatic hernia in a pregnant adult is rare. In contrast to neonatal diaphragmatic hernias, most of the adult patients present with vague gastrointestinal symptoms mimicking other diseases hence the importance of high index of suspicion. We report a case of a young pregnant lady with congenital diaphragmatic hernia presenting with symptoms and clinical signs suggestive of acute pancreatitis. The patient had a laparotomy performed to reduce the hernial content and the diaphragmatic defect was successfully repaired.

Prognosis of Bochdalek Hernia in Neonate after Change in Management Principle

There are considerable controversies in the management of congenital diaphragmatic hernia. By 1997, early operation, routine chest tube on the ipsilateral side and maintainingrespiratory alkalosis by hyperventilation were our principles (period I). With a transition period from 1998 to 1999, delayed operation with sufficient resuscitation, without routine chest tube, and permissive hypercapnia were adopted as our practice. High frequency oscillatory ventilation (HFOV) and nitric oxide (NO) were applied, if necessary, since year 2000(period II). Sixty-seven cases of neonatal Bochdalek hernia from 1989 to 2005 were reviewed retrospectively. There were 33 and 34 cases in period I and II, respectively. The neonatal survival rates were 60.6 % and 73.5 %, respectively, but the difference was not significant. In period I, prematurity, low birth weight, prenatal diagnosis, inborn, and associated anomalies were considered as the significant poor prognostic factors, all of which were converted to nonsignificant in period II. In summary, improved survival was not observed in later period. The factors considered to be significant for poor prognosis were converted to be nonsignificant after change of the management principle. Therefore, we recommend delayed operation after sufficient period of stabilization and the avoidance of the routine insertion of chest tube. The validity of NO and HFOV needs further investigation.

Riñón intratorácico en recién nacido con síndrome de dificultad respiratoria por hernia diafragmática congénita

La hernia diafragmática congénita (HDC) se presenta con frecuencia de 0.17 a 0.57 por 1000 recién nacidos vivos y se asocia con riñón intratorácico (RI) en 0.25%. El objetivo del presente trabajo es describir las dos patología presentes en un neonato y revisar la literatura al respecto. Caso clínico: recién nacido, masculino, quien a las cuatro horas de vida presentó taquipnea de aparición súbita y persistente. Al examen físico: dificultad respiratoria (Silverman de ocho puntos) y cianosis; gases arteriales a su ingreso: hipoxemia e hipocapnia (insuficiencia respiratoria tipo I). Radiografía de tórax: aumento discreto de la trama bronquial y de la densidad parahiliar; pulmones normales, evidencia de membrana pleuroperitoneal y masa sólida superpuesta sobre silueta cardiaca, confirmada por ecocardiograma. Tomografía axial computada (TAC): riñón izquierdo y parte de bazo dentro del tórax, al lado del lóbulo inferior del pulmón izquierdo. Inmediatamente se le instaló al paciente ventilación mecánica convencional y dos días después, se intervino quirúrgicamente para corrección de HDC y descenso de riñón izquierdo. Posterior al acto operatorio, desapareció la sintomatología inicial y su evolución posterior fue satisfactoria. El presente caso ilustra como el riñón en ocasiones puede emigrar al tórax por defecto congénito de la pared del diafragma y ser un hallazgo causal al momento de la exploración radiológica.

Congenital diaphragmatic hernia (CDH) is found frequently in from 0.17 to 0.57 among 1000 newborns and is associated with intrathoracic kidney (IK) in 0.25%. The objective of the present work was to describe both present pathologies in a newborn and to review the literature in this respect. Clinical case: male newborns, who presented tachypnea sudden and persistent for the first 24 h of life. For the that was physical exam, we included breathing difficulty (eight points of Silverman's) and cyanosis; initial arterial gases: hypoxemia and hypocapnia (acute respiratory failure type I); thorax X-ray; increase of bronchial plot and of parahiliary density; normal lungs, pleuroperitoneal membrane and solid mass superimposed on heart silhouette were observed and confirmed by echocardiogram. Computed axial tomography (CAT) revealed left kidney and part of spleen inside thorax, beside inferior lobe of left lung. Immediately, the patient was mechanically ventilated and after 2 days, was operated sourgically for correction of CDH and descent of left kidney. After surgical intervention, initial syntomatology disappeared and evolution was satisfactory. The present case illustrates how the kidney on occasion can emigrate due to congenital default to the thorax of the wall of the diaphragm and be a casual discovery at the moment of radiologic exploration.

Bochdalek Hernia in Neonate

PURPOSE: Repair of congenital diaphragmatic hernias (CDH) has changed from an urgent procedure to a delayed procedure during the last decade. Recently, several new therapeutic methods have been suggested, such as extracorporeal membrane oxygenation, high frequency oscillatory ventilation, partial liquid ventilation, nitric oxide (NO) inhalation, surfactant therapy, and fetal tracheal ligation. Despite recent approaches, CDH remains an unsolved problem with a mortality rate of 35% to 50%. We evaluated the clinical manifestations and the outcomes of newborns that had a Bochdalek hernia. METHODS: The charts of all neonates with a Bochdalek hernia who had been treated at the Division of Pediatric Surgery, Asan Medical Center, from May 1989 to December 1999 were reviewed (n=32). The following para meters were analyzed for survival; gestational age, birth weight, the presence of associated anomalies, the side of defect, the presence of a sac, the position of the stomach, the age at surgery, the availability of high frequency ventilation therapy, and the availability of NO inhalation therapy (1998-1999). RESULTS: Overall, 20 of the 32 newborns survived (62.5%). The average age at gestation was 269 days (range: 202 to 288 days). The average weight at birth was 2,800 gram (range: 856-4,000 grams). There were seven major anomalies. Six patients died without repair. The average age at repair was 39.8 hours (range: 0.5 to 168 hours). The defect was left sided in 23 cases (88.5%). Four had hernia sacs. The stomach had herniated into the chest in 7 of 26 cases. Since 1998, the survival rate has been 7/10 (70.0%). The significant prognostic factors were birth weight and the presence of major anomalies (p<0.05). CONCLUSION: Birth weight and the presence of major anomalies had a significant effect on survival. In neonates with CDH, and careful long-term follow up is required to evaluate strategies using high frequency ventilation and inhaled NO.

Right-side Bochdalek Hernia with Unusual Kidney Herniation in an Old Patient / 대한내과학회지

Bochdalek hernia through Bochdalek foramen, defect at the posterolateral side of the diaphragm is one of the congenital diaphragmatic hernias. It usually occurs in infants, but very rare in old age and also on the right side. We experienced the right-side Bochdalek hernia including kidney herniation in 68 years old man man ifested by hemoptysis. CT scan revealed diaphragmatic defect and herniated liver, colon and kidney. Thoracotomy was performed and the 10 cm-sized large defect was closed with patch. After then, the patient has been well without symptom.

Treatment of bochdalek′s hernia and defect of diaphragm in children / 实用儿科临床杂志

Objective To study the diagnosis and treatment of bochdalek′s hernia in children, especially to introduce the methods of repairing the defect of diaphragm using rib-flap and terylene fabric.Methods The diagnosis, misdiagnosis and methods of repairing of diaphragm in 10 cases of bochdalek′s hernia were retrospectively reviewed, and the findings of reconstruction of diaphragm in 2 cases of defect of diaphragm were analyzed.Results All of the 12 cases were misdiagnosed for the first time. Ten cases were cured through abdominal surgery and 2 cases were cured through reconstruction of diaphragm.Conclusions Bochdalek′s hernias in children are lack of specific clinical manifestation and often misdiagnosed before operation. Early surgical treatment is necessary once the diagnosis is established, and the defect of diaphragm should be reconstructed. The repairment of diaphragm using rib-flap and terylene fabric is a practical methods.
