RESUMO
INTRODUCTION: Necrotizing enterocolitis (NEC) is a life-threatening condition that afflicts neonates. Breastfeeding has demonstrated to play a protective role against it. By administering lipopolysaccharides (LPS) orally in newborn rats (NBR), we have developed an experimental model to induce NEC-like gut damage. Our aim was to assess the macroscopic and microscopic appearance of the gut, to evaluate the presence of NEC and study the role of breast milk (BM). MATERIALS AND METHODS: NBR were divided into 3 groups: Group A (control, n= 10) remained with the mother, group B (LPS, n= 25) was isolated after birth, gavage-fed with special rat formula and oral LPS, then submitted to stress (hypoxia after gavage) and group c (BM, n= 12) was breastfed once after birth, then isolated, and submitted to stress like group B. On day 4, NBR were sacrificed, and intestine was harvested and assessed. RESULTS: In the control group NEC was not present either macroscopically or histologically. Both groups submitted to stress (B and C) presented a global incidence of NEC of 73%. Most of group B developed histologic signs of NEC (85%) and group C showed a statistically lower incidence of NEC (50%, p= 0.04), playing the BM a protective role against NEC (OR= 0.19; 95% CI: 0.40-0.904). CONCLUSION: Our model showed a significant incidence of NEC in NBR (73%) with the same protective role of BM as in newborn humans, achieving a reliable and reproducible experimental NEC model. This will allow us to investigate new potential therapeutic targets for a devastating disease that currently lacks treatment.
INTRODUCCION: La enterocolitis necrotizante (ECN) es una enfermedad potencialmente mortal que afecta a los neonatos, y frente a la que la leche materna ha demostrado tener un papel protector. Administrando lipopolisacáridos (LPS) por vía oral en ratas recién nacidas (RRN), hemos desarrollado un modelo experimental para inducir un daño intestinal similar al que provoca la ECN con objeto de evaluar el aspecto macroscópico y microscópico del intestino, y de ese modo, analizar la presencia de ECN y estudiar el papel que desempeña la leche materna (LM). MATERIAL Y METODOS: Las RRN se dividieron en tres grupos: el grupo A (control, n= 10) permaneció con su madre; el grupo B (LPS, n= 25) fue aislado tras el nacimiento, alimentado por sonda con una fórmula especial para ratas y LPS oral, y sometido a estrés (hipoxia tras sonda); y el grupo C (LM, n= 12) fue alimentado con leche materna tras el nacimiento y posteriormente aislado y sometido a estrés al igual que el grupo B. El día 4 se sacrificó a las RRN y se recuperaron sus intestinos para su posterior evaluación. RESULTADOS: En el grupo de control, no se observó ECN ni macroscópica ni histológicamente, mientras que los dos grupos sometidos a estrés (B y C) presentaron una incidencia global de la ECN del 73%. La mayoría de los sujetos del grupo B desarrollaron signos histológicos de ECN (85%), y los del grupo C registraron una incidencia de la ECN estadísticamente menor (50%, p= 0,04), lo que significa que la LM desempeña una función protectora frente a la ECN (OR= 0,19; IC 95%: 0,40-0,904). CONCLUSION: Nuestro modelo reveló una incidencia significativa de la ECN en RRN (73%), desempeñando la LM la misma función protectora que en el caso de los humanos recién nacidos, lo que significa que este modelo experimental de ECN es fiable y reproducible. Gracias a dicho logro, podremos investigar nuevos y potenciales objetivos terapéuticos para una peligrosa enfermedad que, a día de hoy, carece de tratamiento.

INTRODUCTION: We present the first case of pediatric ileocystoplasty using a purely robotic approach in Spain. CASE REPORT: 12-year-old male with neurogenic bladder of low capacity and high pressures. After failure of conservative treatment, bladder augmentation with ileum patch was decided upon. Surgery was carried out using a purely robotic approach with 4 robotic and 2 accessory ports. Surgery duration was 380 minutes in total, without intraoperative complications. He was discharged 2 weeks after cystographic control. During 32-months follow-up, he has remained continent. DISCUSSION: The minimal invasion, surgical precision and ergonomics made the robotic approach an optimal option for complex surgical techniques. Given the little availability of the robot and the low pediatric volume, its standardization is a challenge. Our accumulated experience is consistent with the current literature and shows promising surgical and esthetic results. We hope this case report will contribute to the divulgation and progressive introduction of robotic surgery in our daily lives.
INTRODUCCION: Presentamos el primer caso de abordaje robótico pediátrico puro en España. CASO CLINICO: Varón de 12 años con vejiga neurógena de escasa capacidad y altas presiones sin respuesta al tratamiento conservador, abogando por una ileocistoplastia de aumento. Se lleva a cabo un abordaje robótico puro con 4 puertos robóticos y 2 accesorios, de 380 minutos de duración total sin complicaciones intraoperatorias. Es dado de alta a las 2 semanas previo control cistográfico. Tras 32 meses de seguimiento continúa continente. COMENTARIOS: La mínima invasión, mayor precisión y ergonomía del abordaje robótico, hacen de éste una opción óptima para técnicas quirúrgicas complejas. Dada la difícil disponibilidad del robot y el escaso volumen pediátrico, resulta un reto su normalización en este campo. Nuestra experiencia coincide con la literatura, mostrando resultados quirúrgicos y estéticos prometedores. Esperamos este reporte contribuya a la difusión e introducción progresiva de la cirugía robótica en nuestra rutina.

OBJECTIVE: Circumcision is one of the most common surgical procedures in pediatric surgery. Even though manual suture (MANS) is regarded as the gold standard technique, easy-to-use mechanical suture (MECS) devices have been recently developed, with better postoperative results in the adult population. The objective of our study was to compare the operating time and incidence of postoperative complications between both techniques in our environment. MATERIALS AND METHODS: A retrospective study of patients undergoing circumcision in our institution from October 2021 to December 2022 was carried out. Operating time and complications observed in the first 14 postoperative days (edema, hematoma, dehiscence) were analyzed according to the technique used (MANS vs. MECS) and patient age (< 12 and ≥ 12 years old). RESULTS: 173 patients (147 MANS, 26 MECS) were included. Mean operating time was significantly lower in MECS patients, both in patients < 12 years old (16 min vs. 10 min, p= 0.002) and in patients ≥ 12 years old (23 min vs. 12 min, p< 0.001). Regarding complications, MECS patients ≥ 12 years old had a lower rate of suture dehiscence (23.5% vs. 0%, p< 0.001), with no significant differences in the younger group. CONCLUSIONS: MECS circumcision is a simple and effective technique involving shorter operating times than MANS circumcision, regardless of age. It has a lower rate of complications in older children (≥ 12 years), which means it stands as a valid alternative to the conventional technique.
OBJETIVOS: La circuncisión es una de las intervenciones quirúrgicas más realizadas en cirugía pediátrica. Aunque la técnica con sutura manual (SMAN) se considera el gold standard, recientemente se han desarrollado dispositivos de sutura mecánica (SMEC) de fácil manejo y con mejores resultados postoperatorios en la población adulta. El objetivo de nuestro estudio es comparar el tiempo quirúrgico y la incidencia de complicaciones postoperatorias entre ambas técnicas en nuestro ámbito. MATERIAL Y METODOS: Estudio retrospectivo de pacientes circuncidados en nuestro centro entre octubre 2021 y diciembre 2022. Se analizó el tiempo quirúrgico y las complicaciones observadas en los primeros 14 días postoperatorios (edema, hematoma, dehiscencia), en función de la técnica empleada (SMAN vs SMEC) y la edad de los pacientes (< 12 y ≥ 12 años). RESULTADOS: Se incluyeron 173 pacientes (147 SMAN, 26 SMEC). El tiempo quirúrgico medio fue significativamente menor en los pacientes con SMEC, tanto en < 12 años (16 min vs. 10 min, p= 0,002) como en ≥ 12 años (23 min vs 12 min, p< 0,001). En cuanto a las complicaciones, los pacientes con SMEC del grupo ≥ 12 años presentaron menor tasa de dehiscencia de sutura (23,5% vs 0%, p< 0,001), sin observarse diferencias significativas en el grupo de menor edad. CONCLUSIONES: La circuncisión con SMEC es una técnica sencilla y eficaz, que precisa un tiempo quirúrgico más reducido que la sutura manual, independientemente de la edad. Presenta menor tasa de complicaciones en los niños de mayor edad (≥ 12 años), por lo que se plantea como una alternativa válida a la técnica clásica.

INTRODUCTION: The minimally invasive approach using robotic technology is fully incorporated in the treatment of adult pathologies. The first international pediatric studies with a robotic approach date from 2002, and in Spain, from 2009. We present the implementation of a Pediatric Robotic Surgery program in our setting. MATERIALS AND METHODS: A proposal for the application of robotic technology in pediatrics was developed, and after the acquisition of a Da Vinci Xi system at our center, a program was initiated under the guidance of a pediatric surgeon experienced in this approach. RESULTS: 732 patients with a median age of 12 years (7 months-17 years) have been operated on since January 2019. 56% of the procedures were abdominal. 3 thoracic approaches and 11 urologic procedures were carried out. 1 conversion to open surgery was performed during a fundoplication. The median combined duration of abdominal and thoracic approaches was 155 minutes (70-380 minutes). There were no anesthetic or hemodynamic complications. The postoperative period in the cases in which the procedure was completed was uneventful, and patients were discharged after a median of 2 days (1-16 days). CONCLUSION: The main advantage of robotic procedures is the symmetrical movement in line with the surgeon's hands, which makes the learning curve shorter. In our experience, the robotic approach has allowed for greater precision in the surgical technique, favoring the patient's recovery.
INTRODUCCION: El abordaje mínimamente invasivo empleando tecnología robótica está plenamente incorporado a la patología del adulto. Las primeras series pediátricas internacionales con abordaje robótico datan del año 2002 y en España del 2009. Presentamos la implementación de un programa de Cirugía Robótica Pediátrica en nuestro centro. MATERIAL Y METODOS: Se elaboró una propuesta de aplicación de la tecnología robótica en el área pediátrica y tras la adquisición de una plataforma Da Vinci Xi en nuestro centro, se procedió al inicio del programa bajo la tutorización de un cirujano pediátrico experimentado en este abordaje. RESULTADOS: Se han intervenido 32 pacientes con una mediana de edad de 12 años (7 meses-17 años) desde enero de 2019. El 56% de los procedimientos fueron abdominales. Se realizaron tres abordajes torácicos y 11 procedimientos urológicos. Se realizó una conversión a cirugía abierta durante una fundoplicatura. La mediana de la duración en conjunto de los abordajes abdominales y torácicos fue de 155 minutos (70-380 minutos). No hubo complicaciones anestésicas ni hemodinámicas. El postoperatorio en los casos en los que se concluyó el procedimiento no presentó incidencias y el alta se realizó con una mediana de 2 días (1-16 días). CONCLUSION: La principal ventaja de los procedimientos robóticos es el movimiento simétrico en línea con las manos del cirujano, lo que hace que la curva de aprendizaje sea más corta. En nuestra experiencia, el abordaje robótico nos ha permitido una mayor precisión en la técnica quirúrgica favoreciendo la recuperación del paciente.

Neonatal appendicitis is a very rare entity associated with immune, vascular, hypoxic, and obstructive factors. We present two cases of neonatal appendicitis with different characteristics. The first case is a 15-day-old newborn with congenital hypothyroidism who had abdominal distension and sepsis data. An appendicular plastron was found. Hirschsprung's disease was ruled out through biopsies. The second case is a 27-week-old preterm newborn with history of necrotizing enterocolitis who presented an incarcerated inguinal hernia consistent with Amyand's hernia. The prognosis of neonatal appendicitis varies according to how fast diagnosis is achieved, since it is associated with high mortality rates in the first hours. Although appendicitis is the condition best known to the pediatric surgeon, it represents a diagnostic challenge in newborns as a result of its extreme rarity and how likely it is to present comorbidities.
La apendicitis neonatal es una entidad infrecuente que asocia factores inmunes, vasculares, hipóxicos y obstructivos. Presentamos dos casos de apendicitis neonatal con diferentes características. El primer caso es un neonato de 15 días de vida con hipotiroidismo congénito. Presentaba distensión abdominal y datos de sepsis. Se halló un plastrón apendicular y se descartó enfermedad de Hirschsprung mediante biopsias. El segundo caso es un prematuro de 27 semanas, con antecedente de enterocolitis necrotizante, que a los 53 días de vida presentó una hernia inguinal incarcerada compatible con hernia de Amyand. El pronóstico de la apendicitis neonatal va unido a la celeridad del diagnóstico, ya que supone una importante mortalidad en las primeras horas. Aunque la apendicitis es el cuadro más conocido por el cirujano pediátrico, a edad neonatal es un reto diagnóstico por su extrema rareza y probable comorbilidad.

OBJECTIVES: To analyze, depending on the technique employed, recurrence, symptomatic improvement and testicular growth following treatment of testicular varicocele. MATERIAL AND METHODS: Descriptive retrospective study of 69 pediatric and adolescent males diagnosed with varicocele treated in our center by open technique according Ivanissevich technique (IT), Palomo (PT) and percutaneous embolization (PE) between 2000-2014. Variables analyzed were age, symptoms, differential testicular volume (RV), employed technique, recurrence, symptomatic improvement and RV after treatment. Association between qualitative variables was evaluated (chi-square test or Fisher's exact test). RESULTS: 69 patients with a median age of 14 years (7-19) were studied. PE was performed in 37 patients (53,6%), PT in 23 (33,3%) and IT in 9 (13%). Recurrence occurred in 16 patients (23,2%), 80% of them had been treated with PE. Eleven patients had pain (15.9%), there was improvement in 100% of patients treated with PE, but none of those treated by PT or IT improved. At diagnosis, 37 patients (53.6%) had decreased testicular volume (left testicular hypotrophy), in 28 cases the RV was >20%. After treatment, the RV was normalized in 11 cases (39,2%). CONCLUSIONS: The choice of therapeutic technique in pediatric varicocele should be based on patient characteristics, symptoms, experience center for embolization and previous recurrence. Regardless of the chosen technique, 39,2% of testicular hypotrophy with VD >20% present at diagnosis normalized after treatment.
OBJETIVOS: Analizar en función de la técnica empleada para tratamiento de varicocele, la recurrencia, alivio sintomático y crecimiento testicular en pacientes pediátricos y adolescentes. MATERIAL Y METODOS: Estudio descriptivo retrospectivo de 69 pacientes pediátricos y adolescentes diagnosticados de varicocele tratados en nuestro centro mediante abordaje abierto según técnica de Ivanissevich (TI), Palomo (TP) y embolización percutánea (EP) entre 2000-2014. Las variables fueron edad, síntomas, volumen testicular diferencial (VD), técnica empleada, recurrencia, mejoría sintomática y VD tras el tratamiento. Se evaluó la asociación entre variables cualitativas (test de Chi cuadrado o prueba exacta de Fisher). RESULTADOS: Se estudiaron 69 pacientes con mediana de edad de 14 años (7-19). Se realizó EP a 37 pacientes (53,6%), TP a 23 (33,3%) y TI a 9 (13%). Presentaron recurrencia 16 (23,2%), de ellos el 80% habían sido tratados mediante EP. Once pacientes tenían dolor al diagnóstico (15,9%), tras el tratamiento 100% de los tratados mediante EP presentaron alivio, mientras que en ninguno de los tratados mediante TI o TP mejoró el dolor. Al diagnóstico 37 pacientes (53,6%) presentaron hipotrofia testicular izquierda, en 28 casos el VD fue >20%. Tras el tratamiento, el VD se normalizó en 11 casos (39,2%). CONCLUSIONES: La elección de la técnica terapéutica de varicocele en pacientes pediátricos y adolescentes debería depender de las características del paciente, presencia de síntomas, experiencia del centro y recurrencia previa. Independientemente de la técnica elegida el 39,2% de hipotrofias testiculares con DV >20% al diagnóstico alcanzaron la normalización del volumen testicular tras el tratamiento.

INTRODUCTION: The aim of this study was to know the epidemiology of burns in teenagers. PATIENTS AND METHODS: Burn patients over 11 years old admitted in our Institution in the last 10 years were included. Etiology, burn size, hospital stay, quirurgical interventions and long term sequelae were registered. RESULTS: One thousand and eight patients were admitted, 89 were over 11 years (8.8%), 70.7% were boys and 29.3% girls. Fire was the principal agent in 58 cases (65.1%), due to fireworks in 13 (22.4%), alcohol in 7 (12%), explosion of flammable containers (spray) in 4 (6.8%) and gasoline in 3 (5.2%). Fireworks injuries and spray explosions affected face and hand in 88% cases. The median hospital stay was 8 days after admission (1 to 90). 83.1% required surgical treatment with mean of 1.8 +/- 1.4 interventions and 21.3% had long-term sequelaes that required at least one surgical intervention. CONCLUSION: Fire is the main cause of burns in adolescents. Fireworks injuries represented a quarter of that lesions, and highlights paint spray explosions as new causative agents. Considering the high morbidity in this age group, with permanent functional and aesthetic sequelae, prevention campaigns are needed to reduce such accidents.

INTRODUCTION: Endoscopic subureteral injection has been successfully used to treat vesicoureteral reflux (VUR) in children. The aim of this study was to review our results with subureteral polydimethylsiloxane injection in terms of effectiveness, long term follow-up and morbidity. MATERIAL AND METHOD: Twenty-eight children with VUR were treated with this technique. VUR was unilateral in eight patients (28.6%) and bilateral in 20 patients (71.4%). Indications for endoscopic treatment were the same as those for open surgery. The polydimethylsiloxane implant was injected transureterally below the ureteral meatus in 50 ureters on an outpatient basis. Reflux grade was low (II-III) in 36% and high (IV-V) in 64%. RESULTS: The mean follow-up was 18 months (12 months-4 years). VUR was corrected in 43 ureters (86%) corresponding to 21 patients. Reflux resolved in 40 ureters after one polydimethylsiloxane injection (80%) and in 43 ureters (86%) after two injections. An endoscopic retreatment to correct the reflux was performed in six ureteral units. Cystoscopic findings in these patients with endoscopic failure were mound displacement toward the bladder neck in five ureters and marked volume loss on the mound in one. All these patients underwent a second subureteral dose, which controlled VUR in three ureters (50%). CONCLUSIONS: Our results confirm that endoscopic subureteral polydimethylsiloxane treatment is a simple procedure with low morbidity that is well tolerated by the patient. In our experience, it can be used in double ureters. The effectiveness of this procedure seems to be related to the grade of reflux, the cystoscopic appearance of the ureteral orifice, volume loss and mound displacement.

BACKGROUND: The manometric effects of surgical repair of gastroesophageal reflux remain largely unknown, making the interpretation of the changes in the esophagogastric high pressure zone after fundoplication difficult. AIM: To measure in a murine model the transdiaphragmatic pressure gradients, intraabdominal esophageal length, and lower esophageal sphincter pressure and length after Nissen fundoplication. MATERIAL AND METHODS: Adult Wistar rats were divided into two groups Control group (n = 10): in which measurements were made after laparotomy and intraabdominal esophageal dissection. Nissen Group (n = 15): in which measurements were made at baseline, after fundoplication and 1 week after surgery. We considered the following variables: end-inspiratory and end-expiratory transdiaphragmatic gradient (TDIG and TDEG respectively), lower esophageal sphincter pressure (LESP) length (LESL), and length of the intraabdominal segment of the esophagus (LIAS). RESULTS: The LIAS increased significantly after esophagogastric dissection in the control group (11.38 +/- 3.22 mm vs 16.02 +/- mm, p < 0.05). No differences between pre- and postoperative status were found in TDIG, TDEG, LESP and LESL in the control group. However, LESP increased significantly after fundoplication (14.22 +/- 13.3 vs 32.96 +/- 7.8 mmHg, p < 0.05) and these differences were still present one week later (30.72 +/- 6.73 mmHg, p < 0.05). LESL was also increased (1.91 +/- 1.76 mm vs 7.68 +/- 1.83 mm) after fundoplication (p < 0.05), and reached 7.02 +/- 2.18 mm (p < 0.05) 1 week later. No differences were found in pre- and postoperative TDIG, TDEG and LIAS in the Nissen Group. CONCLUSION: In this murine experimental model, intraabdominal esophageal dissection increased the length of the intraabdominal esophagus without modifying the esophagogastric high pressure zone, while Nissen fundoplication increased lower esophageal sphincter pressure and length, without modifying the length of the intraabdominal esophagus or the transdiaphragmatic pressure gradients.

BACKGROUND: Some neonates with congenital diaphragmatic hernia (CDH) and persistent pulmonary hypertension are not adequately oxygenated with conventional treatment. The extracorporeal membrane oxygenation (ECMO) has been successful in some of them as an alternative in their management. PATIENTS AND METHODS: We studied the charts of 47 neonates with CDH, symptomatic within 24 hours of birth, treated in our institution during the last seven years (1987-1994). In all of them, conventional ventilation and hemodynamic support was used. In 12 patients high frequency ventilation (HFV) was used and two survived. In all patients we analyzed the following ventilatory and gasometric parameters: Oxygenation index (OI)*, ventilatory index (VI)** and postductal PCO2. In 15 neonates who did not survive, a necropsy was performed and a morphometric parameter, pulmonary index (PI)*** was studied. RESULTS: The overall survival was 60%. VI and OI showed significant differences (p < 0.001) between survivors and non-survivors with values of 460.9 +/- 303 vs 1532 +/- 500.6, respectively for VI and 10.3 +/- 5.7 vs 46.2 +/- 37.8, respectively for IO. There were no significant differences in postductal PCO2. Mean PI in the 15 non-survivors was 0.0072 +/- 0.002 (normal > 0.015). Regression coefficients of PI with OI or VI were not significant. Neonates with VI < 1000 and OI < 40 survived. All patients with VI > 1000 and OI > 40 died. Some babies with VI > 1000 and OI < 40 (21.6%) survived. CONCLUSIONS: In our experience, the use of HFV did not improve the prognosis of these patients, but we believe that the use of ECMO in those patients with VI > 1000, and overall, patients with VI > 1000 and OI < 40 would improve the survival rates of this congenital malformation. *QI = FiO2 x MAP/PO2 postductal x 100. (MAP = Median airway pressure). **VI = VR x MAP (VR = Ventilatory rate). ***PI = Pulmonary weight/Body weight.

Cholangitis has been the most common postoperative complication of Kasai's operation for biliary atresia. A host of ingenious surgical procedures have been used to prevent this complication, some including exteriorization of the bilioenteric conduit. The purpose of this report was to investigate the role of the derivation on the incidence of cholangitis, liver function and the survival of patients with biliary atresia treated with Kasai's operation. We have analyzed the clinical data of thirty-six patients with biliary atresia treated with Kasai's portoenterostomy during a seven year period (1987-1993). The patients were divided into two groups: Group I, patients treated with portoenterostomy and exteriorization of the bilioenteric conduit (n = 18) and Group II, patients treated with portoenterostomy without enterostomy. Our results suggest that the use of the exteriorization of the bilioenteric conduit was not shown to be effective in the prevention of episodes of cholangitis. The survival for both groups was not statistically significant and there was no increase in morbidity after the postoperative period or during the liver transplant.
