Resumen Objetivo: Describir resultados de la cirugía de sustitución esofágica con tubo gástrico invertido, vía ascenso retroesternal en dos hospitales pediátricos durante el período marzo 2015 a marzo 2018. Materiales y Método: Un estudio observacional, transversal, con recolección de datos retrospectivo, donde se incluyeron todos los expedientes de pacientes que presentaban patología del esófago por causa adquirida o congénita que fueron operados de sustitución esofágica con tubo gástrico invertido en dos hospitales pediátricos durante 3 años. Resultados: Encontramos 29 niños sometidos a sustitución esofágica, de los cuales 27 cumplieron criterios de inclusión. La edad comprendida entre 2 y 17 años. El 63% corresponde al sexo femenino. La causa más frecuente de sustitución esofágica es por estenosis esofágica por ingesta caustica (92,59%). El 70% presentó algún tipo de complicación luego de la cirugía. La fístula esofagocutánea es la complicación principal con 33,33%. La permanencia en la unidad de cuidados intensivos es menor de 24 horas en un 74% de los niños. Se inicia la vía oral en casi la mitad de casos entre los 10-12 días de posquirúrgico, la estancia hospitalaria es en promedio 18,5 días. La mortalidad es 3,7%. Conclusión: La sustitución esofágica por tubo gástrico invertido vía ascenso retroesternal, es una técnica comparable en resultados a la interposición de colón. Para los autores, el estómago es un órgano ideal para realizar la reconstrucción esofágica, y sus complicaciones son manejables.

Aim: To describe the results of esophageal replacement surgery with an inverted gastric tube via retrosternal ascent in two pediatric hospitals during the period March 2015 to March 2018. Materials and Method: an observational, cross-sectional study with retrospective data collection that included all the records of patients with esophageal discontinuity due to acquired or congenital causes who underwent esophageal replacement surgery with an inverted gastric tube in two pediatric hospitals for 3 years. Results: We found 29 children undergoing esophageal replacement, of which 27 met inclusion criteria. The age between 2 to 17 years. 63% corresponds to the female sex. The most frequent cause of esophageal replacement is esophageal stricture due to caustic ingestion (92.59%). 70% presented some type of complication after surgery. The esophagocutaneous fistula is the main complication with 33.33%. The stay in the intensive care unit is less than 24 hours in 74% of children. The oral route is started in almost half of cases between 10-12 days after surgery; the hospital stay is on average 18.5 days. Mortality is 3.70%. Conclusión: The esophageal substitution by inverted gastric tube via retrosternal ascent is a technique comparable in results to the interposition of the colon. For the authors, the stomach is an ideal organ to perform esophageal reconstruction, and its complications are manageable.

Comparación de vía mediastinal posterior versus vía retroesternal para el reemplazo de esófago con ascenso gástrico parcial. Motivo de un cambio de estrategia / Comparison of posterior mediastinal versus retrosternal route for esophageal replacement with partial gastric pull-up. Rationale for a change in strategy

Introducción: existen dos rutas para realizar el reemplazo de esófago (RE), la retroesternal (RRE) y la mediastinal posterior (RMP). El objetivo del estudio es comparar los pacientes que recibieron un ascenso gástrico parcial empleando estas dos rutas. Material y métodos: Se revisaron las historias clínicas de 51 pacientes con ascenso gástrico parcial, en 27 años en el Hospital Garrahan. Se utilizó la vía RRE en 25 casos y la RMP en 26. Fueron comparados los datos epidemiológicos de los grupos y las variables para valorar la dificultad del acto quirúrgico, evolución inmediata y alejada. El estudio es comparativo, retro-prospectivo y longitudinal. Resultados: las características generales de los pacientes fueron similares. Los que recibieron el ascenso gástrico por vía RMP presentaron una menor incidencia de dehiscencia (p=0,017), de enfermedad por reflujo gastroesofágico (ERGE) (p=0,001) y de dumping (p=0,0001). No hubo diferencias estadísticamente significativas entre los dos grupos al comparar la duración del procedimiento, días de internación total y en Unidad de Cuidados Intensivos (UCI), días de permanencia en asistencia respiratoria mecánica (ARM), inicio de alimentación oral y estenosis de la anastomosis. Se observó una tendencia clínicamente relevante, que no alcanzó significancia estadística en las complicaciones intraquirúrgicas y número de dilataciones postoperatorias. No hubo necrosis del ascenso. Fallecieron 2 pacientes. Conclusiones: considerando la menor incidencia de dehiscencia, ERGE y dumping reemplazados por RMP, elegimos a ésta como nuestra primera opción para el reemplazo esofágico en la infancia (AU)

Introduction: The two routes for esophageal replacement (ER) are retrosternal (RRE) and posterior mediastinal (PMR). The aim of the study was to compare patients who received a partial gastric pull-up using either of these two routes. Material and methods: The clinical records of 51 patients who underwent partial gastric pull-up over 27 years at the Garrahan Hospital were reviewed. The RRE route was used in 25 and the RMP in 26 cases. The epidemiological data of the groups and the variables to evaluate the complexity of the surgical procedure, and shortand long-term outcome were compared. A comparative, retroprospective, and longitudinal study was conducted. Results: the general characteristics of the patients were similar. Those who underwent gastric pull-up via PMR had a lower incidence of dehiscence (p=0.017), gastroesophageal reflux disease (GERD) (p=0.001), and dumping (p=0.0001). No statistically significant differences were found between the two groups when comparing the duration of the procedure, days of total hospital and intensive care unit (ICU) stay, days on mechanical ventilation (MV), initiation of oral feeding and stenosis of the anastomosis. A clinically relevant trend, which did not reach statistical significance, was observed in intraoperative complications and number of postoperative dilatations. There was no necrosis of the pull-up. Two patients died. Conclusions: considering the lower incidence of dehiscence, GERD, and dumping associated with PMR, this was our first choice for esophageal replacement in infancy (AU)

Effect of muscle relaxants on the prognosis of neonates with congenital esophageal atresia-tracheoesophageal fistula after surgery / 中国当代儿科杂志

OBJECTIVE@#To summarize the experience in the application of muscle relaxants in the perioperative period in neonates with congenital esophageal atresia-tracheoesophageal fistula (EA-TEF).@*METHODS@#A retrospective analysis was performed on the medical data of 58 previously untreated neonates with EA-TEF who were treated in the Neonatal Center of Beijing Children's Hospital, Capital Medical University from 2017 to 2019. The incidence rate of anastomotic leak was compared between the neonates receiving muscle relaxants for different durations after surgery (≤ 5 days and > 5 days). The correlation between the duration of postoperative use of muscle relaxants and the duration of mechanical ventilation was evaluated.@*RESULTS@#Among the 58 neonates with EA-TEF, 44 underwent surgery, among whom 35 with type III EA-TEF underwent thoracoscopic surgery. Among these 35 neonates, 30 (86%) received muscle relaxants after surgery, with a median duration of 4.75 days, and 6 (18%) experienced anastomotic leak. There was no significant difference in the incidence rate of anastomosis leak between the ≤ 5 days and > 5 days groups (@*CONCLUSIONS@#Prolonged use of muscle relaxants after surgery cannot significantly reduce the incidence of anastomotic leak, but can prolong the duration of invasive mechanical ventilation in neonates with EA-TEF. Therefore, prolonged use of muscle relaxants is not recommended after surgery.

Muscle-sparing versus standard posterolateral thoracotomy in neonates with esophageal atresia / Toracotomia posterolateral com poupança muscular versus toracotomia padrão em neonatos com atresia esofágica

ABSTRACT Background : The muscle-sparing thoracotomy (MST) has not yet been thoroughly studied and assessed in comparison to the traditional thoracotomy method in newborns. Aim : To compare the outcomes of MST and standard posterolateral thoracotomy (PLT) in newborns. Methods : Randomized, controlled, double-blind trial on 40 neonates with esophageal atresia, comparing the time of beginning a surgery until seeing the pleura, the duration of hospitalization in the neonatal intensive care unit, the time in ventilator, the time of returning the shoulder function, the time of returning the Moro reflex, and the mortality between the two techniques. Results : The data showed no differences between the two groups in basic information (weight, height, gender, numbers of prematurity neonates and caesarean). The results on the size of the scar in the MST group was significantly lower than in the PLT group. Also, the time of returning the shoulder function in MST group was earlier than in PLT group. There were no significant differences in the duration since the beginning the surgery to see the pleura, the time of being hospitalized in intensive unit, the time that the infant required ventilator, returning time of the Moro reflex in 1st and 3rd months after the operation, and the mortality rates between MST and PLT groups. Conclusion : It seems that the advantages of using MST over PLT procedure in neonates include the earlier shoulder function recovery and also superior cosmetic results.

RESUMO Racional : A técnica de toracotomia poupadora de músculo (MST) ainda não foi estudada e avaliada em relação ao método tradicional de toracotomia em recém-nascidos. Objetivo : Comparar os resultados da MST e toracotomia posterolateral padrão (PLT) em recém-nascidos. Métodos : Ensaio randomizado, controlado, duplamente cego em 40 neonatos com atresia esofágica, comparando o tempo de início da incisão até ver a pleura, a duração da hospitalização na unidade de terapia intensiva neonatal, o tempo em ventilador, o tempo da volta da função do ombro, tempo de retorno do reflexo Moro e mortalidade entre as duas técnicas. Resultados : Os dados não mostraram diferenças entre os dois grupos em informações básicas (peso, altura, gênero, número de neonatos de prematuridade e cesariana). Os resultados sobre o tamanho da cicatriz no grupo MST foram significativamente menores do que no grupo PLT. Além disso, o tempo de retorno da função do ombro no grupo MST foi mais precoce do que no grupo PLT. Não houve diferenças significativas na duração desde o início da operação até a pleura ser vista, o tempo de hospitalização em unidade intensiva, o tempo que a criança necessitou de ventilador, retorno do reflexo Moro nos 1º e 3º meses após a operação, e as taxas de mortalidade entre os grupos. Conclusão : As vantagens de usar o procedimento MST sobre PLT em neonatos incluem a recuperação da função do ombro e também resultados cosméticos superiores.

Background: Dehiscence of esophageal anastomosis is frequent and there are still controversies which type of anastomosis is preferred to diminish its incidence . Aim: To compare end-to-end anastomosis versus end-to-side anastomosis in terms of anastomotic leakage, esophageal stricture and gastroesophageal reflux symptom. Methods: This study was carried out for two year starting from 2012. End-to-side and end-to-side anastomosis were compared in terms of anastomotic leakage, esophageal stricture, gastroesophageal reflux symptom, length of surgery and pack cell infusion. Results: Respectively to end-to-end and end-to-side anastomosis, duration of surgery was 127.63±13.393 minutes and 130.29±10.727 minutes (p=0.353); esophageal stricture was noted in two (5.9%) and eight (21.1%) cases (p=0.09); gastroesophageal reflux disease was detected in six (15.8%) and three (8.8%) cases (p=0.485); anastomotic leakage was found in five (13.2%) and one (2.9%) cases (p=0.203); duration of neonatal intensive care unit admission was significantly shorter in end-to-end (11.05±2.438 day) compared to end-to-side anastomosis (13.88±2.306 day) (p<0.0001). Conclusion: There were no significant differences between end-to-end and end-to-side anastomosis except for length of neonatal intensive care unit admission which was significantly shorter in end-to-end anastomosis group.

Racional: Deiscência de anastomose esofágica é frequente e ainda existem controvérsias qual tipo de anastomose é preferível para diminuir sua incidência. Objetivo : Comparar a anastomose terminoterminal versus a lateroterminal em termos de deiscência de anastomose, estenose de esôfago, e sintoma de refluxo gastroesofágico. Métodos : Este estudo foi realizado por dois anos a partir de 2012. Anastomoses terminoterminal e terminolateral foram comparadas em termos de deiscência de anastomose, estenose de esôfago, sintoma do refluxo gastroesofágico, duração da operação e transfusão. Resultados : Na comparação das anastomoses terminoterminal e terminolateral, respectivamente, a duração em minutos das operações foi de 127.63±13.393 e 130.29±10.727 (p=0,353); estenose esofágica foi observada em dois (5,9%) e oito (21,1%) casos (p=0,09); doença do refluxo gastroesofágico foi detectada em seis (15,8%) e três (8,8%) casos (p=0,485); deiscência de anastomose foi encontrada em cinco (13,2%) e um (2,9%) caso (p=0,203); duração do internamento na UTI neonatal foi significativamente menor na terminoterminal (11,05±2,438 dias) em comparação com terminolateral (13,88±2,306 dias, p<0,0001). Conclusão : Não houve diferença significativa entre as anastomoses terminoterminal e terminolateral, exceto para UTI neonatal que foi significativamente menor no grupo de anastomose terminoterminal.

Reparación toracoscópica de atresia esofágica con y sin fistula traqueoesofágica / Thoracoscopic repair of esophageal atresia with and without tracheoesophageal fistula

Introduction: Esophageal atresia (EA) is the interruption of the continuity of the esophagus, with or without persistent communication with the trachea. Recent advances in surgical techniques have made possible correction with minimally invasive surgery (MIS). Objective: To evaluate the management of thoracoscopic technique in the treatment of EA. Patients and Method: Retrospective analysis of medical records in two centers was carried out between 2007 and 2012. Variables such as gestational age, gender, weight, type of esophageal atresia, malformations, surgery and postoperative complications were recorded. Results: Twenty patients, 15 of them with type III EA, 4 with type I and one unclassifiable, were part of the study. 13 patients underwent ligation, cut of tracheoesophageal fistula and end to end anastomosis. Two underwent laparoscopic gastrostomy and fistula ligation. One patient required conversion and underwent esophagostomy plus gastrostomy. 4 patients without fistula required laparoscopic gastrostomy and aspiration of the proximal esophagus to be able to perform esophageal anastomosis. In the postoperative period, pleural drainage and a transanastomotic feeding tube were installed. Seven patients required esophageal dilations and 4 patients developed stenosis due to reflux. Two had recurrent fistula, one with spontaneous resolution and another with endoscopic resolution. Three children died: two of them due to pathologies not related to surgery and one as a result of limitation of therapeutic effort after fistula patency. Discussion: Esophageal atresia repair with MIS is a safe and effective option with excellent exposure and visualization of anatomic landmarks and little associated morbidity.

Introducción: Atresia esofágica (AE) es la interrupción de la continuidad del esófago, con o sin comunicación con la tráquea. Los avances en cirugía han permitido su corrección con cirugía mínimamente invasiva (CMI). Objetivo: Evaluar el manejo toracoscópico en AE. Pacientes y Método: Revisión retrospectiva de fichas de 2 centros entre 2007 y 2012. Se registraron variables como edad gestacional, sexo, peso, tipo de atresia esofágica, malformaciones, cirugías y complicaciones postquirúrgicas. Resultados: Veinte pacientes, 15 tipo III, 4 tipo I y uno no clasificable. En 13 pacientes se realizó ligadura, sección de fístula tráqueo-esofágica y anastomosis término-terminal. Dos fueron sometidos a gastrostomía laparoscópica más ligadura de fístula. Un paciente requirió conversión y se realizó esofagostomía más gastrostomía. En 4 pacientes sin fístula, se realizó gastrostomía laparoscópica y aspiración del esófago proximal hasta lograr realizar la anastomosis esofágica. En el post-operatorio se instaló drenaje pleural y sonda trans-anastomótica. Siete pacientes requirieron dilataciones esofágicas y 4 desarrollaron estenosis por reflujo. Dos presentaron fístula recidivada, uno con resolución espontánea y el segundo de resolución endoscópica. Tres niños fallecieron: dos por patologías no relacionadas con la cirugía y uno con limitación de esfuerzo terapéutico con repermeabilización de fístula. Discusión: La atresia esofágica reparada con CMI es una opción segura y efectiva en esta serie, permitiendo excelente exposición y visualización de reparos anatómicos, con poca morbilidad asociada.

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.

Patrón clínico-epidemiológico de la infección en el recién nacido intervenido quirúrgicamente / Clinical and epidemiological pattern of infection in surgical newborn

Introducción: en los últimos años la cirugía neonatal ha logrado grandes avances en la supervivencia y en la recuperación de la función de los órganos comprometidos, pero la infección posoperatoria es una de sus principales complicaciones. Objetivo: identificar los factores de riesgo de la infección en el neonato intervenido quirúrgicamente, en el Servicio de Neonatología, durante los años 2005-2012. Métodos: se realizó un estudio descriptivo en el Hospital Pediátrico Universitario William Soler. La población estuvo constituida por 136 neonatos intervenidos quirúrgicamente que se infectaron. Se analizaron: factores de riesgo de la infección y sexo, edad al ingreso, causa y tipo de cirugía, localización de la infección, agente infeccioso y condición al egreso. Resultados: la tasa de infección en el servicio para el periodo fue 26,4 x 100, la menor en 2007 10,0 x 100, y la mayor en 2010 37,9 x 100 (significativamente p= 0,000). En el 90,4 por ciento p(n= 123) la estadía hospitalaria superó los 7 días, y en el 69,9 por ciento(n= 95) el tiempo quirúrgico excedió las 2 horas. El 39 por ciento(n= 53) tuvo infección del sitio quirúrgico, el 19,1 por ciento se intervino por atresia esofágica (n= 26). En el 14,7 por ciento de los pacientes (n= 20) fue aislado el estafilococo coagulasa negativo, y en el 10,3 por ciento el estafilococo aureus (n= 14). El 7,4 por ciento de los recién nacidos falleció (n= 10). Conclusiones: la infección en el recién nacido se manifiesta de forma importante, fundamentalmente a nivel del sitio quirúrgico y por cirugía de atresia esofágica, con predominio de la estadía y tiempo quirúrgico prolongados, involucrados principalmente el estafilococo coagulasa negativo y estafilococo aureus

Introduction: in the last few years, neonatal surgery has made great advances in terms of survival rates and of recovery of the compromised organ's functions, but postoperative infection remains one of the main complications. Objective: to identify the risk factors of infection in the surgical neonate at the Neonatology Service in the period of 2005 to 2012. Methods: a descriptive study was conducted at William Soler university pediatric hospital. The population under research was made up of 136 neonates who had been operated on and had caught infection. The analyzed variables were risk factors for infection and sex, age on admission to the hospital, cause and type of surgery, location of infection, infective agent and patient's condition on discharge. Results: the infection rate at the service for this period was 24.6 x 100, being 10 x 100 the lowest in 2007 and 37.9 x 100 the highest in 2010 (significant p= 0.000). The length of stay at hospital in 90.4 percent of cases (n= 123) exceeded 7 days and the surgical time in 69.9 percent of the group (n= 95) was over 2 hours. Surgical site infection occurred in 39 percent(n= 53) of patients, 19.1 percent(n= 26) was operated on from esophagic atresia; negative coagulase staphylococcus was isolated in 14.7 percent of children (n= 20) whereas staphylococcus aureus was found in 10.3 percent (n= 14). In the study group, 7.4 percent of neonates died (n= 10). Conclusions: infection in the newborn significantly occurs in the surgical site and due to esophagic atresia surgery; long length of stay at hospital and surgical time prevail and the negative coagulase and the aureus staphylococci are mainly involved

Atresia esofágica y fístula traqueoesofágica: evolución y complicaciones postquirúrgicas / Esophageal atresia and tracheoesophagic fistula: evolution and postsurgical complications

Esophageal atresia (EA) and tracheoesophageal fistula are congenital anomalies associated with respiratory and gastrointestinal morbidity. Objective: The aim of this study was to describe clinical characteristics of patients with EA and TEF during childhood, specially focused on respiratory and gastrointestinal complications. Methods: We reviewed the clinical charts from fifteen patients admitted to our hospital and who were followed locally between 1995 and 2007. Results: Gross classification distribution was: A: 0, B: 0, C: 12, D: 2, E: 1. Waterston distribution was Al: 6, B1: 1, B2: 4y C2: 4. Associated malformations to EA and TEF were 7/15. Main morbidity during the follow up period was: Recurrent pneumonia: 6/15, recurrent wheezing 12/15, tracheomalacia in 9/15 and apnea in one patient. Fistula re-opening in 3/15, Gastro esophageal reflux in 15/15 esophagic stenosis in 7/15. All patients were admitted to the hospital at least once during the follow up and in 12/15 of this were due to respiratory causes. Conclusions: EA and TEF after surgical repair have significant respiratory and gastrointestinal morbidity and frequent admission to the hospital during the first years of life.

Perinatal management of common neonatal thoracic lesions.

Esophageal atresia, congenital diaphragmatic hernia, bronchopulmonary malformations and cystic lung diseases are the common neonatal thoracic surgical lesions encountered in practice. The availability of antenatal ultrasonography has lead to these lesions being detected before birth. Antenatal diagnosis can be made with a fair degree of accuracy in tertiary fetal medicine centres. Antenatal intervention is limited in a very few centres in the western world and not being done in India at present. The outcome of these babies with antenatal diagnosis of thoracic lesions has changed in the last decade. Earlier intervention is now possible in cystic lung disease before infectious complication has set in. All these lesions are managed exclusively in well developed neonatal surgery units with excellent outcome in the western world. The present study reviews the antenatal detection, clinical presentation, interventional/surgical procedures [antenatally and postnatally] and outcome of these common neonatal thoracic surgical lesions.
