Thoracoscopic surgery versus traditional open surgery for infants with congenital diaphragmatic eventration: A retrospective cohort study / 中国胸心血管外科临床杂志

@#Objective    To compare and analyze the treatment effect of thoracoscopic surgery and traditional open surgery on infants with congenital diaphragmatic eventration, and summarize the experience of thoracoscopic surgery in infants with congenital diaphragmatic eventration. Methods    We retrospectively analyzed the clinical data of 105 children with congenital diaphragmatic eventration who received operation in the Department of Cardiothoracic Surgery of Children’s Hospital of Chongqing Medical University from January 2010 to January 2019. The patients were divided into an open group and a thoracoscopic group according to the operation methods. There were 41 patients in the thoracoscopic group, including 30 males and 11 females, with an average of 13.42±11.08 months (range: 1 d to 3 years). There were 64 patients in the open group, including 44 males and 20 females, with an average age of 8.21±9.33 months (range: 15.0 d to 1.6 years). The operation time, intraoperative bleeding volume, postoperative mechanical ventilation time, hospital stay and other operation indexes as well as the mortality, recurrence rate and complication rate of the two groups were observed. Results    The operation indexes such as operation time, intraoperative bleeding volume, postoperative mechanical ventilation time, thoracic drainage time, CCU stay and hospital stay of the thoracoscopic group were better than those in the open group (P<0.05). There was no statistical difference between two groups in postoperative diaphgram muscles descent, postoperative feeding time or patients needing thoracic drainage (P>0.05). The incidence of postoperative complications in the thoracoscopic group (19.51%) was lower than that in the open group (23.44%, P>0.05), and the difference in mortality and recurrence rate between the two groups was not statistically significant (P>0.05). Conclusion    Both thoracoscopic diaphragmatic plication and traditional open surgery can effectively treat congenital diaphragmatic eventration, but compared with traditional open surgery, thoracoscopic diaphragmatic plication has the advantages of shorter operation time, less trauma, more rapid recovery and fewer complications, so it should be the first choice for children with congenital diaphragmatic eventration.

Thoracoabdominal compartment syndrome complicating right-sided diaphragmatic eventration with co-existent unilateral renal agenesis

Diaphragmatic eventration (DE) associated with intestinal malrotation and renal agenesis is a rare entity. The authors report a case of a 69-year-old man who had symptoms of heart failure. He had a previous imaging diagnosis of right diaphragmatic eventration and dilated cardiomyopathy. He died on the second day after the hospital admission and had a post mortem examination that confirmed complete right diaphragmatic eventration, intestinal malrotation, left renal agenesis, dilated cardiomyopathy, and anteriorly rotated right kidney and had findings suggestive of a thoracoabdominal compartment syndrome. Thoracoabdominal compartment syndrome is described as transmission of abdominal pressure through a defective diaphragm causing compression of the hemithorax viscera and mediastinal shift with a hemodynamic alteration. The association of these anomalies is rare, and the possibility of this finding in a patient with eventration should always be considered.

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)

Four-Dimensional CT of the Diaphragm in Children: Initial Experience

OBJECTIVE: To evaluate the technical feasibility of four-dimensional (4D) CT for the functional evaluation of the pediatric diaphragm. MATERIALS AND METHODS: In 22 consecutive children (median age 3.5 months, age range 3 days–3 years), 4D CT was performed to assess diaphragm motion. Diaphragm abnormalities were qualitatively evaluated and diaphragm motion was quantitatively measured on 4D CT. Lung density changes between peak inspiration and expiration were measured in the basal lung parenchyma. The diaphragm motions and lung density changes measured on 4D CT were compared between various diaphragm conditions. In 11 of the 22 children, chest sonography was available for comparison. RESULTS: Four-dimensional CT demonstrated normal diaphragm (n = 8), paralysis (n = 10), eventration (n = 3), and diffusely decreased motion (n = 1). Chest sonography demonstrated normal diaphragm (n = 2), paralysis (n = 6), eventration (n = 2), and right pleural effusion (n = 1). The sonographic findings were concordant with the 4D CT findings in 90.9% (10/11) of the patients. In diaphragm paralysis, the affected diaphragm motion was significantly decreased compared with the contralateral normal diaphragm motion (−1.1 ± 2.2 mm vs. 7.6 ± 3.8 mm, p = 0.005). The normal diaphragms showed significantly greater motion than the paralyzed diaphragms (4.5 ± 2.1 mm vs. −1.1 ± 2.2 mm, p < 0.0001), while the normal diaphragm motion was significantly smaller than the motion of the contralateral normal diaphragm in paralysis (4.5 ± 2.1 mm vs. 7.6 ± 3.8 mm, p = 0.01). Basal lung density change of the affected side was significantly smaller than that of the contralateral side in diaphragm paralysis (89 ± 73 Hounsfield units [HU] vs. 180 ± 71 HU, p = 0.03), while no significant differences were found between the normal diaphragms and the paralyzed diaphragms (136 ± 66 HU vs. 89 ± 73 HU, p = 0.1) or between the normal diaphragms and the contralateral normal diaphragms in paralysis (136 ± 66 HU vs. 180 ± 71 HU, p = 0.1). CONCLUSION: The functional evaluation of the pediatric diaphragm is feasible with 4D CT in select children.

Reparación protésica en una paciente con hernia incisional catastrófica / Prosthetic repair in a patient with catastrophic incisional hernia

Se presenta el caso clínico de una paciente de 66 años de edad, blanca, con antecedentes de hipertensión arterial, diabetes mellitus de tipo II y sobrepeso, quien fue operada en el Hospital General Universitario Dr Juan Bruno Zayas Alfonso de Santiago de Cuba por presentar una eventración gigante en la pared abdominal anterior, que no le permitía deambular sin apoyo. Se realizó la reparación protésica que resultó eficaz y segura, con 13 años sin recurrencia

The case report of a 66 years white patient with a history of hypertension, type II diabetes mellitus and overweight is presented, who was operated on at Dr Juan Bruno Zayas Alfonso University General Hospital in Santiago de Cuba due to a considerable eventration in the front abdominal wall that didn't allow her wandering around without support. The prosthetic repair which was effective and safe, was carried out with no recurrence during 13 years

Atypical Neonatal Marfan Syndrome with p.Glu1073Lys Mutation of FBN1: the First Case in Korea

Neonatal Marfan syndrome (nMFS) is considered to be on the most severe end of the spectrum of type I fibrillinopathies. The common features of nMFS include ascending aortic dilatation, severe mitral and/or tricuspid valve insufficiency, ectopia lentis, arachnodactyly, joint contractures, crumpled ear, loose skin, and pulmonary emphysema.We describe a newborn male diagnosed with nMFS. He presented several atypical features, such as diaphragmatic eventration, severe hydronephrosis with hydroureter, and dilated cisterna magna. Molecular analysis revealed a missense mutation at nucleotide 3217 (c.3217G>A) in exon 26 of the fibrillin-1 (FBN1) gene, resulting in the substitution of a glutamate for a lysine at codon 1073 (E1073K) in the 12th calcium binding epidermal growth factor-like domain of the FBN1 protein. Here we report a rare case of Nmfs with several combined atypical features, such as diaphragmatic eventration, severe hydronephrosis with hydroureter, and dilated cisterna magna. Our report is the first atypical nMFS case with p.Glu1073Lys mutation of FBN1 in Korea and may help clinicians with the diagnosis and follow-up of atypical nMFS.

Is polysomnographic examination necessary for subjects with diaphragm pathologies?

OBJECTIVES: While respiratory distress is accepted as the only indication for diaphragmatic plication surgery, sleep disorders have been underestimated. In this study, we aimed to detect the sleep disorders that accompany diaphragm pathologies. Specifically, the association of obstructive sleep apnea syndrome with diaphragm eventration and diaphragm paralysis was evaluated. METHODS: This study was performed in Süreyyapasa Chest Diseases and Thoracic Surgery Training and Research Hospital between 2014-2016. All patients had symptoms of obstructive sleep apnea (snoring and/or cessation of breath during sleep and/or daytime sleepiness) and underwent diaphragmatic plication via video-assisted mini-thoracotomy. Additionally, all patients underwent pre- and postoperative full-night polysomnography. Pre- and postoperative clinical findings, polysomnography results, Epworth sleepiness scale scores and pulmonary function test results were compared. RESULTS: Twelve patients (7 males) with a mean age of 48 (range, 27-60) years and a mean body mass index of 25 (range, 20-30) kg/m2 were included in the study. Preoperative polysomnography showed obstructive sleep apnea syndrome in 9 of the 12 patients (75%), while 3 of the patients (25%) were regarded as normal. Postoperatively, patient complaints, apnea hypopnea indices, Epworth sleepiness scale scores and pulmonary function test results all demonstrated remarkable improvement. CONCLUSION: All patients suffering from diaphragm pathologies with symptoms should undergo polysomnography, and patients diagnosed with obstructive sleep apnea syndrome should be operated on. In this way, long-term comorbidities of sleep disorders may be prevented.

Eventración diafragmática en el adulto. Reporte de un caso / Diaphragmatic eventration in adults. Case report

Resumen Introducción: El diafragma es un órgano fibromuscular cuya función fisiológica es otorgar la fuerza mecánica para la ventilación. Otra de las funciones del diafragma es dividir la cavidad torácica de la cavidad abdominal2. El diafragma se ve afectado rara vez por enfermedades. Entre las patologías primarias se encuentra la eventración diafragmática. Reporte de caso: Paciente del sexo femenino de 21 años de edad sin antecedentes de importancia quien presenta caída de su propia altura y trauma contuso en tórax. Se realiza radiografía como parte del estudio y se observa elevación del hemidiafragma izquierdo. El estudio se complementa con tomografía axial computada y se diagnostica eventración diafragmática. Ante los hallazgos, se plantea el procedimiento quirúrgico como terapia definitiva; sin embargo, la paciente no lo acepta, por lo que se ha mantenido en seguimiento por la consulta externa. Discusión: La eventración diafragmática es causada por debilidad de la parte muscular diafragmática. Se cree que es causada por la ausencia congénita o funcional de la musculatura diafragmática. El cuadro clínico generalmente es asintomático; en caso de existir sintomatología, ésta se relaciona a problemas respiratorios. El diagnóstico se corrobora con estudios radiológicos, de los cuales los más utilizados son la radiografía de tórax y la tomografía axial computada. El tratamiento puede ser conservador o quirúrgico. El pronóstico dependerá del grado de hipoplasia pulmonar y la de coexistencia de alguna otra alteración. Conclusión: La eventración diafragmática es rara vez diagnosticada en pacientes adultos asintomáticos. El manejo dependerá de la decisión del cirujano y del paciente.

Abstract Background: The diaphragm is a fibromuscular organ whose primary function is related to ventilation. It also serves as a barrier between pleural and abdominal cavities. This organ is rarely affected by pathologic entities, but eventration is among the primary diseases of this structure. Case Report: We present the case of a 21 year old female with no relevant personal history. She arrived to the emergency room with thoracic blunt trauma. Chest radiography is indicated, showing elevation of the left hemidiaphragm. This study was complemented with a computed tomography making a presumptive diagnosis of diaphragmatic eventration. As part of the treatment, we proposed surgical therapy but the patient refused and now she is under surveillance in her clinic. Discussion: Diaphragmatic eventration is caused by the weakness of the muscular part of the organ. It is thought that is caused by functional or congenital absence of the diaphragmatic musculature. The clinical presentation is variable but, in most of the cases, the patients are asymptomatic. The diagnosis is made by radiologic studies such as chest plains and computed tomography. Treatment could be conservative or surgical. The prognosis will depend on the degree of pulmonary hypoplasia and the coexistence of other malformations. Conclusion: Diaphragmatic eventration is rarely diagnosed in adults and the treatment will depend on the surgeon´s and the patient´s joined decision.

Abordaje fisioterapéutico en paciente con eventración compleja / Physiotherapeutic approach in patient with complex eventration

Eventración diafragmática en pediatría: revisión de un caso y revisión de la literatura / Diaphagmatic eventration in children: a case report and review of the literature

Diaphragmatic eventration is an abnormal elevation of one of the hemidiaphragms, with deviation of the mediastinum to the contralateral side. It is usually asymptomatic. It can be either congenital or acquired. If it is asymptomatic, the patient should be kept under observation. The resolution must be surgical if the ascent of the diaphragm is pointed, if there is any symptom or recurrent pneumonia. This article describes the case of a patient with congenital diaphragmatic eventration. The difficulties the patient presented in the diagnosis are reviewed.

La eventración diafragmática es la elevación anormal de uno de los hemidiafragmas, con desviación del mediastino hacia el lado contralateral, generalmente asintomática. Se clasifica en congénita y adquirida, si es asintomática el paciente se debe mantener en observación, la resolución debe ser quirúrgica si el ascenso diafragmático es acentuado, presenta síntomas o neumonía recurrente. En este artículo se revisa el caso de un paciente con eventración diafragmática congénita, que presentó dificultades en el diagnóstico.

A “Near Miss" Congenital Eventration of the Right Hemidiaphragm in A Neonate: A Case Report

Focal eventration involving the posterior segment of the hemidiaphragm is a rare congenital anomaly. We report of a 10- day-old infant who presented with significant respiratory insufficiency and failure to show any responses to standard treatment. The diagnosis of focal eventration of the diaphragm was not anticipated until ultrasonographic examination revealed the defect. Diaphragmatic plication resulted in complete resolution of symptoms. A high level clinical awareness is crucial as a relatively simple surgical procedure could avert long term life-threatening complications.

Gastric Volvulus with Eventration of Diaphragm

Gastric volvulus with eventration of diaphragm is an uncommon occurrence. We report here case of a middle-aged woman who came with left-sided chest pain since 1 month, and occasional history of breathlessness in supine position. She was advised to have chest radiograph and ECG done. ECG was within normal limits. On chest radiograph, there was smooth, round, well-defined elevation of left hemidiaphragm with air fluid levels below it. Mediastinum was shifted towards right side. Based on that, barium meal was advised which showed contrast filling with alteration of axis of stomach. Organoaxial type of gastric volvulus is confirmed.

Open Transthoracic Plication of the Diaphragm for Unilateral Diaphragmatic Eventration in Infants and Children

BACKGROUND: To evaluate our experience of early surgical plication for diaphragmatic eventration (DE) in infancy and childhood. METHODS: This study evaluated infants and children with symptomatic DE who underwent plication through an open transthoracic approach in our childhood development department between January 2005 and December 2012. Surgical plication was performed in several rows using polypropylene U-stitches with Teflon pledgets. RESULTS: The study included 12 infants and children (7 boys and 5 girls) with symptomatic DE (9 congenital and 3 acquired). Reported symptoms included respiratory distress (91.7%), wheezing (75%), cough (66.7%), and recurrent pneumonia (50%). Preoperative mechanical ventilatory support was required in 41.7% of the patients. The mean length of hospital stay was 6.3+/-2.5 days. The mean follow-up period was 24.3+/-14.5 months. Preoperative symptoms were immediately relieved after surgery in 83.3% of patients and persisted in 16.7% of patients one year after surgery. All patients survived to the end of the two-year follow-up and none had recurrence of DE. CONCLUSION: Early diagnosis and surgical plication of the diaphragm for symptomatic congenital or acquired diaphragmatic eventration offers a good clinical outcome with no recurrence.

Two Cases of Congenital Diaphragmatic Hernia Manifestated with Atypical Symptoms in Newborn Infants / 대한주산의학회잡지

Most of the congenital diaphragmatic hernia (CDH) cases are diagnosed at prenatal period or immediately after birth with severe respiratory symptom. The classic triad, which is respiratory distress, apparent dextrocardia and a scaphoid abdomen, is usually seen in this period. Several case reports have described older infants and children with a wide spectrum of symptoms of CDH, whereas extremely few cases were reported in neonatal period except classic triad such as straungulation of the bowel. These atypical manifestations can lead physician to delayed diagnosis. We report two cases of CDH newborns. First case was diagnosed with pneumoperitoneum following tension pneumothorax, transient diaphragm eventration on 5 days after birth. The other case was diagnosed with failure to thrive and mediastinal mass on 30 days after birth. These cases suggest physicians to consider CDH in late newborn period with pneumoperitoneum following tension pneumothorax, transient diaphragm eventration, failure to thrive, and mediastinal mass.

Objective: to show the advantages of the Laparomesh mesh for the prevention and repair of incisional hernia. Methods: an observational, descriptive, longitudinal and prospective study was conducted in 37 patients who had been operated on in Manuel Fajardo and Juan Bruno Sayas teaching hospitals in Havana and Santiago de Cuba, respectively, from November 2008 to June 2013. They had midline incisional hernias or were at risk of developing them, so they underwent hernioplasty with Laparomesh mesh. Results: the average age was 46 and males prevailed. Spinal or general anesthesia was used as well as prophylaxis with cefazolin. Conclusions: there have been no manifestations of rejection to the prosthetic material up to now. Neither immediate complications norhernial recurrence have been so far observed with an average follow-up of 36 months(AU)

Presentación de un paciente con eventración diafragmática / Presentation of a Patient with Diaphragmatic Eventration

La eventración diafragmática constituye una rara anomalía congénita del diafragma que se presenta debido a una embriogénesis deficiente con atrofia de las fibras musculares del diafragma, transformación de conjuntiva y pérdida del tono muscular. Se presentó el caso de un paciente de 45 años de edad, mestizo, con antecedente de sufrir asma bronquial que acudió a Consulta de Cirugía del Centro Integral de Salud Salvador Allende, Caracas, en septiembre de 2011, refirió episodios de disnea y dolor torácico que se incrementaba con el ejercicio físico. Al examen clínico se detectaron ruidos hidroaéreos en hemitórax izquierdo lo que motivó la indicación de estudios radiográficos que evidenciaron la presencia de una eventración diafragmática de grandes proporciones; fue sometido a intervención quirúrgica con plicatura diafragmática con excelentes resultados.

The diaphragmatic eventration is a rare congenital anomaly of the diaphragm due to a deficient embryogenesis of the diaphragm, with atrophy of muscular fibers, conjunctive transformation and loss of the muscular tone. A 45- year-old male patient with history of asthma who came to Surgery Consultation of Salvador Allende Health Center, Caracas, in September 2011, with episodes of dyspnea and thoracic pain that was increasing with physical exercise. The examination revealed hydroaerial noises to the left hemithorax and radiographic exams were done, the diaphragmatic eventration diagnosis of big proportions was revealed. The surgical treatment was determined by diaphragmatic plication with excellent results.

Distocia de hombros y eventración diafragmática / Shoulder dystocia and diaphragmatic hernia

Introducción: la distocia de hombros es un evento impredecible que puede ser leve o grave. En el período neonatal constituye el factor de riesgo más importante para lesión del plexo braquial y una causa excepcional de eventración diafragmática por injuria del nervio frénico. Presentación del caso: se presenta un recién nacido producto de parto distócico por distocia de hombros, que nace severamente deprimido y en su evolución requiere soporte ventilatorio prolongado. Conclusiones: el estudio fluoroscópico concluyó una eventración diafragmática derecha, permaneciendo con un síndrome de dificultad respiratoria de aproximadamente un mes de evolución y sin requerir tratamiento quirúrgico hasta el momento actual. Las complicaciones más frecuentes fueron la bronconeumonía y las atelectasias a repetición. Se realizó una revisión actualizada del tema destacándose diagnóstico etiológico. Se presentan fotos previo consentimiento familiar.

Introduction: shoulder dystocia is an unpredictable event that can be mild or severe. In the neonatal period is the most important risk factor for brachial plexus injury and an exceptional cause of diaphragmatic hernia by phrenic nerve injury. Case presentation: a newborn is presented after a shoulder dystocia delivery, born severely depressed and whose evolution requires prolonged ventilatory support. Conclusions: in the fluoroscopic study we concluded right diaphragmatic hernia, with respiratory distress syndrome approximately of one month of evolution and without requiring surgical treatment to date. The most frequent complications were repeated bronchopneumonia and atelectasis. An updated review of the literature highlighting etiologic diagnosis was made. Photos are presented prior parental consent.

Aspectos clínicos y quirúrgicos de las hernias incisionales complejas / Clinical and surgical aspects of the complex incisional hernias

El diagnóstico y tratamiento de las hernias incisionales complejas constituye un tema obligado para todos los cirujanos, cuyo desafío es prevenir las complicaciones y disminuir las recurrencias, lo que justifica la realización de este estudio con el objetivo de identificar sus aspectos clínicos y quirúrgicos más relevantes. Métodos: se realizó un estudio observacional, descriptivo de serie de casos correspondiente a 320 pacientes operados electivos por hernias incisionales complejas en el servicio de cirugía del Hospital Universitario Dr Juan B Zayas de Santiago de Cuba durante 15 años (1994-2009). Resultados: predominó el sexo femenino y el grupo etario de 31 a 60 años. Las hernias suprapúbicas fueron las más frecuentes en ambos sexos; en mujeres con intervenciones ginecológicas previas y en hombres, prostáticas. El neumoperitoneo progresivo preoperatorio y la antibioticoterapia profiláctica se aplicaron a todos los pacientes. Las técnicas quirúrgicas más utilizadas fueron las de Jean Rives y Robert Bendavid y la bioprótesis de polipropileno. Índice de recurrencia de 6,5 por ciento con predominio del sexo masculino. El tiempo quirúrgico fluctuó de 1 a 2 horas y la estadía hospitalaria entre 1 y 3 días. Fallecieron 4 pacientes, el 1,3 por ciento de la serie. Conclusiones: el único tratamiento efectivo para las hernias incisionales complejas radica en la técnica quirúrgica sin tensión con aplicación correcta de la bioprótesis indicada y su fijación con la sutura de su mismo material, por lo que se recomienda la protocolización y clasificación de estas hernias para unificar criterios con respecto a su diagnóstico y tratamiento(AU)

Diagnosis and treatment of complex incisional hermias is a compulsory topic for all surgeons. The challenge ahead is to prevent complications and to reduce relapses, which warrants the conduction of a study with the objective of identifying their most relevant clinical and surgical aspects. Methods: Observational and descriptive study of a case series involving 320 patients operated on from complex incisional hernias at the surgery service of Dr Juan B Zayas university hospital in Santiago de Cuba during 15 years (1994-2009). Results: Females and 31-60 years age group predominated. The suprapubic hernias were the most frequent in both sexes; in females who underwent previous gynecological interventions and in men who underwent prosthatic procedures. Preoperative progressive pneumoperitoneum and prophylactic antibiotic therapy were applied to all patients. The most used surgical techniques were Jean Rives' and Robert Bendavid's and the polypropylene bioprothesis. The relapse index was 6.5 percent and males predominated. The surgical time ranged 1 to 2 hours and the stay at hospital lasted one to 3 days. Four patients died, which accounted for 1.3 percent of the case series. Conclusions: The only effective treatment for complex incisional hernias lies in non-tensile surgical technique with correct application of the indicated bioprothesis and its fixing with a suture of the same material, so protocoling and classification of these hernias are recommended in order to unify criteria with respect to their diagnosis and treatment(AU)

Evaluación por imágenes del diafragma en el niño / Image evaluation of diaphragm in children

The anatomy, embriology andfunctions of the neonate 's diaphragm, as well as its anatomical and functional oddities were reviewed. And, in a deeper way, imaging studies were also reviewed; these have an important role in functional and anatomic evaluation of the diaphragm, each one with its own advantages and limitations. Chest X-rays allow an anatomic two dimensional evaluation of the diaphragm and constitutes the first approach in the study of diaphragm pathology in children; hence, the normal anatomy and the most common pathological signs are reviewed. Digestive tube studies using contrast media still are the best choice for diagnosis of hiatal hernia and of herniation through the foramen of Morgagni, where the colon is ascended. Ultrasound use is highlighted for the evaluation of diaphragmatic motility, as well as some of its advantages over fluoroscopy, which is and has been the method of choice in the diagnosis of diaphragmatic paralysis in children. Multiplanar images are the most complete method for the anatomic evaluation of the diaphragm, since they show its spatial orientation and allow the detailed evaluation of those pahologies where the anatomy is altered, such as diaphragmatic hernias, trauma and tumors.

Revisamos la embriología, anatomía y funciones del diafragma, sus particularidades anatómicas y funcionales en los neonatos y, en forma más profunda, los estudios por imágenes, que en la actualidad tienen un importante rol en su evaluación anatómica y funcional, cada uno de ellos con sus ventajas y limitaciones. La radiografía de tóraxpermite una evaluación anatómica en dos planos del diafragma y constituye la primera aproximación en el estudio de la patología del diafragma en los niños, por lo que se describe la anatomía normal y los signos de las patologías más frecuentes. Los estudios contrastados del tubo digestivo siguen siendo de elección para el estudio de las hernias hiatales y hernias de Morgagni en donde está ascendido el colon. Destacamos el uso del ultrasonido en la evaluación de la motilidad diafragmática, y algunas de sus ventajas sobre la fluoroscopia, que es y ha sido el método de elección en el diagnóstico de la parálisis diafragmática en los niños. Las imágenes multiplanares son un método más completo en la evaluación anatómica del diafragma, muestran mejor su orientación espacial y permiten la evaluación detallada de las patologías donde la anatomía está alterada, como hernias diafragmáticas congénitas, trauma y tumores.

Consideraciones actuales sobre las hernias incisionales complejas / Current considerations on the complex incisional hernias

Las hernias incisionales complejas se caracterizan por tener un anillo mayor de 10 cm, con un gran saco, cuyo volumen es mayor que la capacidad de la cavidad abdominal y que al reducir el contenido dentro de ésta produce un síndrome de hipertensión abdominal, con alteraciones de la ventilación pulmonar y hemodinámicas, el cual puede llegar a ser un síndrome compartimental. En la actualidad su prevención constituye un desafío para los cirujanos que realizan este tipo de cirugía cuyo objetivo es evitar las complicaciones y disminuir las recurrencias. El tratamiento de las hernias incisionales complejas requiere del empleo obligatorio de bioprótesis por cirujanos con profundos conocimientos anatómicos y funcionales de la pared abdominal y dominio de la técnica quirúrgica sin tensión, fijación de la malla con sutura del mismo material que ésta, y la utilización de antibioticoterapia profiláctica, además de la aplicación del neumoperitoneo progresivo con una correcta evaluación preoperatoria de estos enfermos. Se recomienda la protocolización y clasificación de estas hernias, así como realizar estudios multicéntricos para la unificación de criterios con respecto a su diagnóstico y tratamiento preventivo y curativo.
