RESUMO
INTRODUCTION: Acute appendicitis is the most frequent cause of acute abdomen in children. The objective of this study was to analyze the causes, approach, and results of complications requiring surgery following appendectomy. MATERIAL AND METHODS: A retrospective study of the appendectomies conducted in three third-level institutions from 2015 to 2019 was carried out. Complications, causes, and number of re-interventions, time from one surgery to another, surgical technique used, operative findings at baseline appendectomy according to the American Association for the Surgery of Trauma (AAST) classification, and hospital stay were collected. RESULTS: 3,698 appendicitis cases underwent surgery, 76.7% of which laparoscopically, with 37.2% being advanced (grades II-V of the AAST classification). Mean operating time was 50.4 minutes (49.8 ± 20.1 for laparoscopy vs. 49.9 ± 20.1 for open surgery, p > 0.05), and longer in patients requiring re-intervention (68.6 ± 27.2 vs. 49.1 ± 19.3, p < 0.001). 76 re-interventions (2.05%) were carried out. The causes included postoperative infection (n = 46), intestinal obstruction (n = 20), dehiscence (n = 4), and others (n = 6). Re-intervention risk was not impacted by the baseline approach used (open surgery or laparoscopy, OR: 1.044, 95% CI: 0.57-1.9), but it was by appendicitis progression (7.8% advanced vs. 0.7% incipient, OR: 12.52, 95% CI: 6.18-25.3). There was a tendency to use the same approach both at baseline appendectomy and re-intervention. This occurred in 72.2% of laparoscopic appendectomies, and in 67.7% of open appendectomies. The minimally invasive approach (50/76) was more frequent than the open one (27 laparoscopies and 23 ultrasound-guided drainages vs. 26 open surgeries) (p < 0.05). 55% of obstruction patients underwent re-intervention through open surgery (p > 0.05). CONCLUSION: Re-intervention rate was higher in advanced appendicitis cases. In this series, the minimally invasive approach (laparoscopic or ultrasound-guided drainage) was the technique of choice for re-interventions.
INTRODUCCION: La apendicitis aguda es la causa más frecuente de abdomen agudo en niños. El objetivo de este trabajo es estudiar las causas, abordaje y resultados de las complicaciones que requieren intervención quirúrgica después de la apendicectomía. MATERIAL Y METODOS: Estudio retrospectivo de las apendicectomías realizadas en 3 centros de tercer nivel entre 2015-2019. Se recogieron las complicaciones, causas y número de reintervenciones, intervalo entre ambas cirugías, técnica empleada, hallazgos operatorios según la Clasificación de la American Association for the Surgery of Trauma (AAST) en la apendicectomía inicial y tiempo de ingreso. RESULTADOS: Se intervinieron 3.698 apendicitis, un 76,7% por vía laparoscópica, encontrando un 37,2% evolucionadas (grado II-V de la clasificación AAST). El tiempo medio quirúrgico fue de 50,4 minutos (laparoscopia 49,8 ± 20,1 vs. laparotomía 49,9 ± 20,1, p > 0,05), superior en aquellos pacientes que requirieron reintervención (68,6 ± 27,2 vs. 49,1 ± 19,3, p < 0,001). Se realizaron 76 reintervenciones (2,05%). Las causas fueron: infección postoperatoria (n = 46), obstrucción intestinal (n = 20), dehiscencia (n = 4) y otras (n = 6). El abordaje inicial no influyó en el riesgo de reintervención (laparotomía o laparoscopia, OR 1,044, IC 95% 0,57-1,9), pero sí el grado de evolución de la apendicitis (7,8% evolucionadas vs. 0,7% incipientes, OR 12,52, IC 95% 6,18-25,3). Hubo una tendencia a reintervenir por el mismo abordaje que la apendicectomía, esto ocurrió en un 72,2% de las apendicectomías laparoscópicas y en un 67,7% de las apendicectomías abiertas. El abordaje mínimamente invasivo (50/76) fue más frecuente que la laparotomía (27 laparoscopias y 23 drenajes ecoguiados frente a 26 laparotomías) (p < 0,05). El 55% de los pacientes obstruidos se reintervinieron por vía abierta (p > 0,05). CONCLUSION: El índice de reintervención fue superior en las apendicitis evolucionadas. En esta serie, el abordaje mínimamente invasivo (laparoscópico o drenaje ecoguiado) fue la técnica de elección en las reintervenciones.

INTRODUCTION: The range of indications for endoscopic treatment of vesicoureteral reflux opens more and more until including correction of secondary reflux (VUR) after ureteral reimplantation. However these cases suppose a technical challenge due to postoperative changes. The aim of this work is to present our experience on endoscopic treatment for VUR in ureteral units with Cohen reimplantation surgery, with special interest in the technical peculiarities of the procedure. MATERIAL AND METHODS: A retrospective study of cases of secondary VUR after reimplantation surgery treated by subureteral injection. TECHNIQUE: We put the needle perpendicular to submucous tunnel and inject medially to hole forming a wheal on the anterior face that occludes the meatus RESULTS: During the 1993-2016 period 21 injections were performed in 15 ureteral units. The ureteral pathology included primary VUR (4), duplex system with lower pole reflux (4), megaureter (3) and ureterocele (2). Average patient age was 5.7 years old (2-12). Succesful outcome had been got in 10 ureteral units (66.67%), a decrease of VUR grade in 4 (26.67%) and perseverance/no resolution of grade IV VUR in 1 (6.67%) DISCUSSION: The anti-reflux mechanism of reimplantation depends on optimizing the submucosous tunnel. This subgroup of pacients is small and there are few studies, hindering the agreement on the most appropiate technique. CONCLUSION: Endoscopic treatment of secondary reflux after reimplantation surgery is a procedure with certain technical feature, but safe and effective offering an alternative prior to surgical reoperation.

INTRODUCTION: Rhabdomyosarcoma (RSM) becomes the most common tumour of the soft tissues during the paediatric age. It represents among 2-3% of child tumours. The genital-urinary location is the second most common location, only after head and neck. The treatment is usually medical, being the surgery a mere contribution, except for the cases in which the situation is not under control, when very aggressive surgery is necessary. The aim of this study is to analyse the cases of genial-urinary RMS that have been treated in our centre and the role that surgery has in their treatment. MATERIAL AND METHODS: Retrospective study of 20 patient (7 girls and 13 boys) with a median age of 24 months (range from 1 month to 12 years) with RMS in the aurochs-genial tract who have been treated in our hospital from 1990 to 2012. The variables described are demographic, location of the primary tumour, state at diagnosis, received treatment, both medical and surgical, with greater emphasis on the kind of surgery applied and monitoring in terms of survival. RESULTS: The location of the primary tumour was: bladder (6), paratesticular (5), vagina (3) retroperitoneal space (3), lesser pelvis (2) and prostate (1). All of them received medical treatment with chemotherapy and radiotherapy following International Society of Pediatric Oncology protocol after diagnostic biopsy. Surgery, which was always used as help, was: reappraisal of biopsy (1), orchiectomy (5), tumoral resection (8) and radical surgery (cystoprostatectomy or pelvic exenteration) in 6 patients. There were 3 deaths, 2 because of the evolution of the disease and 1 because of postoperative sepsis. The survival rate is 80% with a median follow - up of 14 years. CONCLUSIONS: The RMS is the most common tumour of soft tissues in childhood and the genital-urinary location is the second most common after the parameningeal one. The treatment is multidisciplinary and the surgery has a contributing role when there is no answer to the medical treatment or when there is a residual tumour even if some patients do not respond to medical treatment and they need a radical surgery for recovery.
INTRODUCCION: El rabdomiosarcoma (RMS) constituye el tumor de tejidos blandos más frecuente en la edad pediátrica, representando el 2-3% de los tumores infantiles. La localización genitourinaria es la segunda en frecuencia tras la cabeza y cuello. El tratamiento suele ser médico, quedando la cirugía como coadyuvante, excepto en casos no controlados en que se precisan cirugías muy agresivas. El objetivo del estudio es analizar los casos de RMS de localización genitourinaria tratados en nuestro Centro y el papel que la cirugía tiene en su tratamiento. MATERIAL Y METODOS: Estudio retrospectivo de 20 pacientes (7 niñas y 13 niños) con una mediana de edad de 24 meses (rango de 1 mes a 12 años) con RMS del tracto urogenital tratados en nuestro Hospital desde 1990 hasta 2012. Se describen variables demográficas, localización del tumor primario, estadio al diagnóstico, tratamiento recibido, tanto médico como quirúrgico, con especial atención al tipo de cirugía realizada y seguimiento en términos de supervivencia. RESULTADOS: La localización del tumor primario fue: vejiga (6), paratesticular (5), vagina (3), retroperitoneo (3), pelvis menor (2) y próstata (1). Todos recibieron tratamiento médico con quimioterapia y radioterapia según protocolo de la Sociedad Internacional de Oncología Pediátrica (SIOP) previa biopsia diagnóstica. La cirugía, practicada en todos los casos como coadyuvante fue: reevaluación por biopsia (1), orquiectomía (5), resección tumoral (8) y cirugía radical (cistoprostatectomía o exanteración pélvica) en 6 pacientes. Hubo 3 fallecimientos, 2 por progresión de la enfermedad y 1 por sepsis postoperatoria. Los 17 restantes están vivos, lo que supone una supervivencia del 80% con una mediana de seguimiento de 14 años. CONCLUSIONES: El RMS es el tumor de tejidos blandos más frecuente en la infancia y la localización genitourinaria la segunda en frecuencia tras las parameníngeas. El tratamiento es multidisciplinar y la cirugía tiene un papel coadyuvante en casos de no respuesta al tratamiento médico o de tumor residual aunque hay pacientes que no responden al tratamiento médico y precisan de cirugía radical para su curación.
RESUMO
PURPOSE: Kidney stone disease in children is a rare pathology, with a low incidence in Spain (1/4,500 hospitalized children). The spontaneous expulsion rate is about 34-47% which means that more of 50% of children need active treatment. Paediatric patients forming urinary stones have a high risk of recurrence, therefore, a standard diagnosis and treatment are needed. We present our experience in urolithiasis treatment in children. MATERIALS AND METHODS: We reviewed retrospectively all the patients ≤ 16 years hospitalized in our hospital with urolithiasis diagnosis from 2000 to 2013, citing treatment modality, stone-free rates and complications. RESULTS: A total of 69 patients with a mean age of 8,2 years (range 1-16 years) were treated in our hospital during that period. The main clinical presentation was pain (52%). The diagnosis was made by abdominal ultrasounds in all cases. About localization, 21 lithiasis were found in distal urether (UD), 8 in medium urether (UM), 3 in proximal urether (UP) and 13 in renal pelvis (PR). The mean size was 13 mm. 21 (30%) patients had a spontaneous expulsion of the stone, 14 (20%) patients were treated with extracorporeal shock wave lithotripsy and in 22 (32%) patients the elected therapy was ureterosopic stone fragmentation (n = 13) or removal (n = 9). No complications were observed. The overall stone-free rate was 79% (n = 55). CONCLUSIONS: Kidney stone disease in children is a rare pathology, with its own features about diagnosis and treatment, which requires medical care in a specialized center. The optimal treatment should be considered regarding the age of the patient, localization and size of the stone, as well as the team experience.

The aim of this essay is to present our initial experience with laparoscopic pyeloplasty and highlight how some specific technical changes allowed us to improve our results. We performed a chart review of the patients that underwent laparoscopic pyeloplasty in our institution. We included patients older than 6 months old with proved stenosis of the ureteropelvic junction. We compared our first patients with the last ones in which we performed laterocolic approach in all left pyeloplasties and included a modification of the technique to place an external ureteric stent. We performed 13 laparoscopic pyeloplasties, 8 male patients and 5 female. There were 3 right pyeloplasties (23%) and 10 left ones (77%). We performed transmesocolic approach in 2 cases (left) and laterocolic approach in 11. Mean surgical time was 184 minutes in the first 8 cases and 142 in the 5 last ones. We had three cases of complications in the first group, two stents migrated to ureter and one postsurgical infection. In the last cases we had a postoperative bleeding. Laparoscopic approach is an effective option for pyeloplasty with similar results to those of the open approach in spite of a longer surgical time. Experience and specific surgical details allow us to reduce complication rate and surgical time.
