RESUMO

INTRODUCTION: There are various alternatives available for renal pelvis drainage following pyeloplasty. One of them is the use of an internal-external diversion stent, which according to our protocol, is knotted 48 hours following surgery, prior to discharge, and removed 7 days later on an outpatient consultation basis, with no sedation or analgesia required. OBJECTIVE: To analyze the results of patients under one year of age who underwent open pyeloplasty associated with an outpatient internal-external diversion stent. MATERIALS AND METHODS: A retrospective, descriptive analysis of 28 patients (31 renal units) undergoing surgery from 2011 to 2021 was carried out. Diagnostic methods, indications, surgical approach, and postoperative progression were assessed. RESULTS: 28 patients (23 male) prenatally diagnosed with hydronephrosis confirmed by ultrasonography and/or renogram underwent pyeloplasty at a median age of 3 months (15 days-11 months). Pyeloplasty was conducted according to the Anderson-Hynes technique or dismembered pyeloplasty in 28 renal units, and according to the Culp-DeWeerd technique or spiral flap in 3. In all cases, an internal-external diversion stent was used according to our protocol. Mean hospital stay was 3.5 days (2-7 days), with a good postoperative progression. 2 patients had complications (urinary infection requiring intravenous antibiotics, and pyonephrosis requiring re-pyeloplasty). CONCLUSIONS: Using an internal-external diversion stent following pyeloplasty in patients under 1 year of age with ureteropelvic junction obstruction is a simple and safe option that allows for early discharge with outpatient management. It also avoids a second general anesthesia for drainage catheter removal purposes.


INTRODUCCION: Existen diversas alternativas para el drenaje de la pelvis renal tras una pieloplastia. Una de ellas es la utilización de un catéter de derivación interno-externo que, según nuestro protocolo, se anuda a las 48 horas posoperatorias previas al alta y se retira a los siete días de forma ambulatoria en consulta, sin necesidad de sedoanalgesia. OBJETIVO: Analizar los resultados de los pacientes menores de un año intervenidos mediante pieloplastia abierta, asociando un catéter de derivación interno-externo de manejo ambulatorio. MATERIAL Y METODOS: Análisis descriptivo retrospectivo de 28 pacientes (31 unidades renales) intervenidos entre los años 2011 y 2021. Se evaluaron métodos diagnósticos, indicaciones, abordaje quirúrgico y evolución posoperatoria. RESULTADOS: Veintiocho pacientes (23 varones) con diagnóstico prenatal de hidronefrosis confirmado con ecografía y/o renograma, fueron intervenidos mediante pieloplastia a una mediana de edad de tres meses (15 días-11 meses). Se realizó pieloplastia según técnica de Anderson-Hynes o pieloplastia desmembrada en 28 unidades renales y según técnica de Culp-DeWeerd o colgajo en espiral en 3. En todos los casos se utilizó un catéter de derivación interno-externo según protocolo. El tiempo medio de ingreso fue 3,5 días (2-7 días) con buena evolución posoperatoria. Dos pacientes presentaron complicaciones (infección urinaria que requirió antibioterapia intravenosa y pionefrosis que requirió repieloplastia). CONCLUSIONES: Asociar un catéter de derivación interno-externo a la pieloplastia en pacientes menores de un año con estenosis de la unión pieloureteral es una opción sencilla y segura que permite un alta precoz con manejo ambulatorio y evita una segunda anestesia general para la retirada del catéter de drenaje.

RESUMO

Objetivos. El gold standard para el tratamiento de la invaginación ileocólica en el paciente estable sin complicación radiológica es el enema hidrostático. No hay unanimidad sobre si la sintomatología prolongada de invaginación influye en los resultados de dicho tratamiento. El objetivo de este estudio es determinar si el enema hidrostático es efectivo y seguro en pacientes con clínica de invaginación ileocólica mayor de 24 horas. Material y métodos. Estudio retrospectivo de los pacientes diagnosticados de invaginación ileocólica en nuestro hospital entre 2014 y 2017. Hemos dividido en 2 grupos a los pacientes a los que se realizó enema en función del tiempo de clínica, mayor o menor de 24 horas. El análisis estadístico se realizó mediante el test exacto de Fisher. Resultados. En este periodo se atendieron 59 niños con invaginación ileocólica con duración variable de los síntomas (2 horas a 7 días). Del total de pacientes, en 49 se realizó enema hidrostático inicial con una efectividad del 91,8% (45 pacientes). En el grupo de clínica <24 horas (33 pacientes, 67,3%) se objetivó una efectividad del 93,9% y en el grupo de clínica >24 horas (16 pacientes, 32,7%) se objetivó una efectividad del 87,5%. No hubo diferencias significativas al comparar la efectividad entre ambos grupos (p=0,588). En ningún paciente hubo complicaciones tras el enema. Conclusiones. El empleo del enema hidrostático en pacientes con clínica prolongada de invaginación es efectivo y seguro. Consideramos que debería ser la primera herramienta terapéutica en el paciente estable sin complicación radiológica, independientemente del tiempo de evolución


Purpose. Hydrostatic enema is the gold standard treatment for ileocolic intussusception in stable patients without radiologic complication. There is no consensus about the influence of long history of symptoms in the outcome of this treatment. The aim of this study is to determine whether hydrostatic enema is effective and safe in patients with history of ileocolic intussusception of over 24 hours. Materials and methods. Retrospective review of all patients with ileocolic intussusception admitted to our hospital between 2014 and 2017. We divided the patients in whom enema was attempted on into two groups according to the length of history: over or under 24 hours. Statistical analysis was done by using the Fisher's exact test. Results. In this study period 59 children presented with ileocolic intussusception. Duration of symptoms was variable (range 2 hours-7 days). Of the total of patients, initial hydrostatic enema was attempted on 49, with a success rate of 91.8% (45 patients). In the group of his-tory <24 hours (33 patients, 67.3%) we observed a 93.9% effectiveness and in the group >24 hours (16 patients, 32.7%) effectiveness was 87.5%. Success rate showed no significant difference when compar-ing both groups (p=0.588). No complications were seen after enema reduction. Conclusions. The use of hydrostatic enema in patients with long history of intussusception is successful and safe. We consider it to be the first-line treatment in stable patients with no radiologic complication, regardless the duration of symptoms

RESUMO

El síndrome de Steinert congénito es una forma severa de distrofia miotónica, caracterizada por hipotonía generalizada, diplejía facial, dificultad respiratoria y anomalías en la succión y deglución presentes desde el nacimiento. Este síndrome tiene una incidencia de 1 caso por cada 10.000 recién nacidos y una mortalidad del 50% en el período neonatal. Se considera un reto para el anestesiólogo debido a la gran variedad de complicaciones que se pueden presentar en el intraoperatorio y postoperatorio, tanto por la evolución de la enfermedad como por la susceptibilidad a la gran mayoría de los anestésicos. Describimos el caso de un niño de 3 años con distrofia miotónica congénita, en el que se realiza una orquidopexia bilateral por laparoscopia con anestesia general sin relajación muscular, combinada con un bloqueo TAP bilateral ecoguiado


Congenital Steinert syndrome is a severe form of myotonic dystrophy, characterized by general hypotonia, facial diplegia, respiratory difficulty and sucking and swallowing problems presented since birth. This syndrome has an estimated incidence of 1 per 10.000 births. Mortality is close to 50% during the neonatal period. It represents a challenge for the anesthesiologist due to the great variety of intraoperative and postoperative adverse events, given by both the evolution of the disease and the susceptibility to the vast majority of the anesthetic agents. A report of a 3-year-old boy with congenital myotonic dystrophy is presented, scheduled for laparoscopic bilateral orchidopexy, performed under general anesthesia without muscular relaxation, combined with ecoguide bilateral TAP block

RESUMO

Objetivos: Creación de un protocolo de manejo del cuerpo extraño (CE) en vía aérea (VA) basado en una escala de probabilidad. Material y método: Estudio retrospectivo observacional de pacientes con sospecha de aspiración de CE en 15 años. Los parámetros fueron valorados con un SCORE que contempla atragantamiento presenciado, estridor y sibilancias durante el atragantamiento, hipoventilación unilateral y radiografía alterada. Dicha escala los relaciona con una probabilidad de presencia de CE en VA, donde una puntuación ≤ 1 se asocia a menos de un 10% y ≥ 4 a > 50%. Según la probabilidad se plantea: observación, TAC o instrumentación de VA. A continuación se intentó optimizar en función de nuestra casuística. Resultados: Se analizaron 109 pacientes (mediana 25 meses), identificándose CE en 88, principalmente frutos secos. De las variables predictoras solo fueron significativas: la hipoventilación unilateral y la radiografía alterada. En nuestra serie se observó la misma probabilidad ascendente entre la escala y la presencia de CE, excepto en la puntuación de 1 que fue del 57%, lo que atribuimos a un sesgo de información. Si el CE no era fruto seco, material inorgánico o hueso, era muy improbable su aspiración (p= 0) por lo que lo incluimos en el SCORE con un -1. Conclusiones: La aplicación de la escala implicaría la realización de un 7,5% más de TAC en pacientes sin CE pero evitando un 8,5% de instrumentaciones de la VA. Nuestros resultados presentan un sesgo de información, propio de un estudio retrospectivo. Actualmente hemos iniciado la implementación prospectiva


Introduction: The aim is to create a protocol for the managing of foreign body aspiration in children based on a probability scale. Material and methods: Retrospective observational study, including patients admitted with suspected foreign body aspiration (FBA) in the last 15 years. The parameters were assessed with a SCORE that included witnessed choking, stridor and wheezing during choking, unilateral reduced air entry and abnormal X-Ray. This scale relates them to a probability of FBA, where a score ≤ 1 is associated with less than 10% and ≥ 4 with more than 50% of FBA. According to the probability, we propose: observation, chest Computed Tomography (CT) or bronchoscopy. Then, we tried to adapt it to our casuistry. Results: A total of 109 children admitted between 2002-2017 were included. The median age was 25 months, a foreign body was found in 88 patients, the most frequent being organic (seeds and nuts). Significant predictors of FBA were unilateral reduced air entry and abnormal X-Ray. In our study, we found the same ascending probability between the scale and the presence of foreign body, except for SCORE 1, which was 57% what we attribute to an information bias. If the foreign body were not nuts, inorganic or bone, its aspiration was very unlikely, that is why we included it in the SCORE with -1. Conclusions: The use of the algorithm would imply the performance of 7% more of CT in patients without a FBA, but avoiding an 8.5% of bronchoscopy. Our results present an information bias, characteristic of a retrospective study

RESUMO

OBJECTIVE: The low incidence of gastroschisis makes impossible a consistently study of the factors that determine its evolution. The presence of other alterations associated is an important determinant of prognosis known. We analyze the factors implicated in morbidity and mortality in our center that can be modified. MATERIAL AND METHODS: We performed a retrospective study from hospital records. We analyzed the morbidity and mortality versus gestational age, mode of delivery, surgery performed, presence of prenatal diagnosis, herniated viscera and associated anomalies. We studied the postoperative differences occurred as a result of implantation of fetal surgery group. The variables were analyzed with SPSS 15.0 using non-parametric test. RESULTS: Since 1987 25 patients have been operated (12 men) with a mean birth weight of 2,328 g +/- 364. The 44% of them had prenatal diagnosis and 72% were born by cesarean. Only 4 had intestinal atresia. Preterm birth (< 36 weeks) did not improve the complications, but did reduce hospital stay in 10.68 days and the time of parenteral nutrition in 6 days. Cesarean delivery and prenatal diagnosis was improved all the previous factors. Primary closure however was associated with higher rates of postsurgical complications (46.2% vs. 18.2%). The 5 patients who died was during the immediate postoperative period, all before developing the fetal diagnostic program. CONCLUSIONS: Prenatal diagnosis and preterm delivery by elective cesarean reduces the complications of gastroschisis. Interdisciplinary coordination is essential to improve the prognosis of these patients.

RESUMO

UNLABELLED: With the modern techniques, we can resolve almost the totallity of hypospadias. But there are patients with recurrent fistulas associated to uretral stenosis that can finish all the surgical possibilities. MATERIAL AND METHODS: Retrospective review. Lateral based flap uretroplasty consists in the exposition of the uretra, to reconstruct in one-stage the original neourethra with the lateral skin of the penis. RESULTS: From 2008, we have correct 5 patients with a mean age of 12,1 years (9-15) and a weight of 55,34 kg (22-98 kg). All of them were previously corrected 3 to 7 times, with recurrent fistulas. At the office, stenosis urethral was verified. Surgical correction was made in 90-110 minutes and results were positive in all patients, correcting the stenosis after a follow-up of more than a year. Only the oldest two patients had present minimally glans fistula. CONCLUSIONS: Lateral based flap urethroplasty is a useful technique for the correction of the complicated fistulas, allowing the correction of the fistulas and the stenosis of the urethra.

RESUMO

Objetivo. La baja incidencia de la gastrosquisis impide el estudio consistente de los factores que determinan su evolución. La presencia de otras alteraciones asociadas es un factor determinante del pronóstico muy conocido. Queremos analizar los factores implicados en la morbi-mortalidad en nuestro centro, que podamos modificar. Material y métodos. Realizamos un estudio descriptivo retrospectivo a partir de los registros hospitalarios. Analizamos la morbi-mortalidad frente a la edad gestacional, tipo de parto, cirugía realizada, existencia de diagnóstico prenatal, vísceras herniadas y anomalías asociadas. Estudiamos las diferencias postoperatorias acontecidas a raíz de la implantación del grupo de cirugía fetal. Los variables se analizan con SPSS 15.0 utilizando test no paramétricos. Resultados. Desde 1987 se han intervenido 25 pacientes (12 varones), con un peso medio al nacimiento de 2.328 g ± 364. De ellos un 44% presentaban diagnóstico prenatal y el 72% nació por cesárea. Sólo 4 presentaban atresia intestinal. El parto pretérmino (<36 semanas) no mejoró las complicaciones, pero sí redujo la estancia hospitalaria en 10,68 días y el tiempo de nutrición parenteral en 6 días. El parto por cesárea y el diagnóstico prenatal si mejoró todos los factores previos. El cierre primario, sin embargo, se asoció a mayor tasa de complicaciones post-quirúrgicas (46,2% vs. 18,2%).Los 5 pacientes fallecidos fueron, durante el post-operatorio inmediato, todos antes del desarrollo del programa de diagnóstico fetal. Conclusiones. El diagnóstico prenatal y el parto pretérmino por cesárea electiva reducen las complicaciones de las gastrosquisis. Es fundamental la coordinación interdisciplinaria para mejorar el pronóstico de estos pacientes (AU)


Objective. The low incidence of gastroschisis makes impossible a consistently study of the factors that determine its evolution. The presence of other alterations associated is an important determinant of prognosis known. We analyze the factors implicated in morbidity and mortality in our center that can be modified. Material and methods. We performed a retrospective study from hospital records. We analyzed the morbidity and mortality versus gestational age, mode of delivery, surgery performed, presence of prenatal diagnosis, herniated viscera and associated anomalies. We studied the postoperative differences occurred as a result of implantation of fetal surgery group. The variables were analyzed with SPSS 15.0 using non-parametric test. Results. Since 1987 25 patients have been operated (12 men) with a mean birth weight of 2,328 g ± 364. The 44% of them had prenatal diagnosis and 72% were born by cesarean. Only 4 had intestinal atresia. Preterm birth (<36 weeks) did not improve the complications, but did reduce hospital stay in 10.68 days and the time of parenteral nutrition in 6 days. Cesarean delivery and prenatal diagnosis was improved all the previous factors. Primary closure however was associated with higher rates of postsurgical complications (46.2% vs. 18.2%). The 5 patients who died was during the immediate postoperative period, all before developing the fetal diagnostic program. Conclusions. Prenatal diagnosis and preterm delivery by elective cesarean reduces the complications of gastroschisis. Interdisciplinary coordination is essential to improve the prognosis of these patients (AU)

RESUMO

Las técnicas habituales de los hipospadias permiten resolver la práctica totalidad de esta patología con resultados muy positivos. Desgraciadamente, existen pacientes que se fistulizan repetidas veces, agotando las posibilidades quirúrgicas. Generalmente se asocian a estenosis uretral. Queremos presentar una técnica que nos ha facilitado la reparación de estos pacientes con resultados esperanzadores . Material y métodos. Revisión retrospectiva de una serie de casos. La técnica del colgajo lateral pediculado consiste en un desmontaje dela uretra y exposición de la misma, para proceder a su reconstrucción en un solo tiempo por medio de la piel lateral de la uretra que se tubulariza sobre la neouretra primitiva. Resultados. Desde 2008 hemos intervenido 5 pacientes con una edad media de 12,1 años (9-15) y un peso de 55,34 kg (22-98 kg).Previamente habían sufrido de 3 a 7 operaciones de corrección de hipospadias, siempre fistulizadas. En consulta se comprobó la estenosis uretral en todos los pacientes. La intervención se realizó en un tiempo de 90-110 minutos y los resultados fueron favorables en todos los pacientes, resolviéndose las estenosis, con un seguimiento medio superior al año. Tan solo los dos pacientes más mayores han presentado mínimas fístulas glanulares. Conclusiones. La uretroplastia con colgajo lateral pediculado es una técnica útil para el tratamiento de los hipospadias complicados permitiendo la resolución de las fístulas y, especialmente, de las estenosis de uretra (AU)


With the modern techniques, we can resolve almost the totallity of hypospadias. But there are patients with recurrent fi stulas associated touretral stenosis that can finish all the surgical possibilities. Material and methods. Retrospective review. Lateral based flapuretroplasty consists in the exposition of the uretra, to reconstruct in one-stage the original neourethra with the lateral skin of the penis. Results. From 2008, we have correct 5 patients with a mean age of 12,1 years (9-15) and a weight of 55,34 kg (22-98 kg). All of them were previously corrected 3 to 7 times, with recurrent fistulas. At the office, stenosis urethral was verified. Surgical correction was made in 90-110 minutes and results were positive in all patients, correcting the stenosis after a follow-up of more than a year. Only the oldest two patients had present minimally glansfistula. Conclusions. Lateral based flap urethroplasty is a useful technique for the correction of the complicated fistulas, allowing the correction of the fistulas and the stenosis of the urethra (AU)

RESUMO

INTRODUCTION: Barium enema was the first method used for the diagnosis of Hirschsprung's disease, with the appearance of anorectal manometry and its combination with rectal suction biopsy, barium enema has lost value as a diagnosis method but it has also gain importance to decide the surgical technique that will be used for the correction of the disease. AIM: To determine the correlation between the length of the affected segment showed by barium enema valued and the length of the removed piece. MATERIALS AND METHODS: We have studied all Hirschsprung disease's cases diagnosed and treated in our center since 1998, 127 patients underwent Soave-Boley's technique and 51 De La Torre's descent technique. Routinely preoperative barium enema was performed in all cases and determine the location of the transition zone and compared with the aganglionic segment's length specified by pathologist. RESULTS: At 90% of cases the transition zone could be seen at barium enema, it's most common location was rectosigmoid. After statistically analysis the length measured at radiology tests and the length of the anatomic piece showed a low correlation (kappa index 0.0159), being highest values at rectosigmoid transition and very low values at long affected segments. CONCLUSIONS: Barium enema in Hirschsprung's disease is valuable to decide the best surgical technique in each singular case but not to determine the exact length of affected segments. In case of a aganglionic long-segment suspicion, biopsies may be necessary to determinate preoperative length of affected segments.
