15 years' experience in the single-port laparoscopic treatment of pediatric varicocele with Ligasure® technology. / Quince años de experiencia en el tratamiento laparoscópico del varicocele pediátrico con un solo puerto de trabajo y tecnología Ligasure®.

INTRODUCTION: Varicocele is an abnormal dilatation of the internal spermatic veins of the spermatic cord. It has an estimated prevalence of 15% in young male adults. Even though most of them are asymptomatic, scrotal pain and testicular hypotrophy are frequent in children and adolescents. There is controversy regarding the indications and optimal approach for treatment purposes. We present the results of our 15-year series in the laparoscopic repair of pediatric varicocele. MATERIALS AND METHODS: 238 patients diagnosed with varicocele and undergoing laparoscopic repair from 2006 to 2020 were reviewed. Variables collected included age, symptoms, grade, testicular atrophy, hospital stay, perioperative complications, recurrences, and formation of reactive hydrocele. Mean follow-up was 5.6 years (6 months-9 years). RESULTS: Mean age was 14.1 years. 188 patients had grade III varicocele. In 14 cases, varicocele was bilateral. Testicular atrophy at diagnosis was found in 42% of patients, 74% of whom were over 15 years old. 51 patients had testicular pain. All patients underwent laparoscopic treatment. Mean operating time was 36 min. Median hospital stay was 31 h. Recurrence rate was 2.1%. 43 patients (18%) developed hydrocele, but only 27 (11.2%) required hydrocelectomy according to Lord's plication at least 1 year following laparoscopy. Of the remaining 16 cases, 2 spontaneously resolved and 14 remained stable in the mean 7-year follow-up. In 7.1%, paresthesias were noted in the anterior-internal aspect of the left thigh. CONCLUSION: Based on our series, we believe laparoscopy should be regarded as the gold standard technique in the pediatric population. Laparoscopic varicocelectomy is technically easy and fast, causes no pain, and has a recurrence rate of 1%. The procedures involving lymphatic vessel preservation could reduce reactive hydrocele rates as a long-term complication to a minimum.

INTRODUCCION: El varicocele es una dilatación anormal de las venas espermáticas internas del cordón espermático. Su prevalencia se estima en 15% de varones adultos jóvenes. Aunque la mayoría son asintomáticos, en niños y adolescentes el dolor escrotal y la hipotrofia testicular son frecuentes. Existe controversia sobre las indicaciones y el abordaje óptimo para su tratamiento. Presentamos los resultados de nuestra serie de 15 años en la reparación laparoscópica del varicocele pediátrico. MATERIAL Y METODOS: Revisamos 238 pacientes diagnosticados de varicocele y sometidos a corrección laparoscópica desde 2006 hasta 2020. Las variables registradas fueron: edad, síntomas, grado, atrofia testicular, duración de la estancia, complicaciones perioperatorias, recidivas y formación de hidrocele reactivo. El seguimiento medio fue 5,6 años (6 meses-9 años). RESULTADOS: La edad promedio fue 14,1 años. 188 pacientes presentaban varicocele grado III. En 14 casos el varicocele era bilateral. Se observó atrofia testicular en 42% al diagnóstico, de los que el 74% eran mayores de 15 años. Cincuenta y un pacientes refirieron dolor testicular. Todos los pacientes se sometieron al tratamiento laparoscópico. El tiempo operatorio promedio fue 36 min. La mediana de estancia fue 31 horas. La tasa de recidiva fue 2,1%. Cuarenta y tres pacientes desarrollaron hidrocele (18%); pero solo 27 precisaron hidrocelectomía según plicatura de Lord al menos un año poslaparoscopia (11,2%). De los 16 restantes, dos se resolvieron espontáneamente y 14 se mantuvieron estables en el seguimiento medio de siete años. En 7,1% se notificaron parestesias en la cara anterointerna del muslo izquierdo. CONCLUSION: Basándonos en nuestra serie, creemos que la laparoscopia debe considerarse el gold standard en edad pediátrica. La varicocelectomía laparoscópica es técnicamente fácil y rápida, indolora y con una tasa de recurrencia del 1%. Los procedimientos de preservación de los linfáticos podrían reducir al mínimo las tasas de hidrocele reactivo como complicación a largo plazo.

A cross-sectional study of cryptorchidism in children: testicular volume and hormonal function at 18 years of age.

PURPOSE: To evaluate the relationship between unilateral or bilateral criptorchidism, patient age, primary location of the gonad and modality of treatment with testicular volume and hormonal status at 18 years in patients diagnosed and treated for cryptorchidism during childhood. MATERIALS AND METHODS: Testicular volume, LH, FSH, and testosterone were evaluated in 143 young men at 18 years treated in childhood for unilateral (n=103) or bilateral (n=40) cryptorchidism. RESULTS: Unilateral cryptorchidism: Location of testis was prescrotal in 36 patients, inguinal in 52 and non-palpable in 15. The mean volume was 9.7 mL compared to 16.2 L. for the spontaneously descended testicle in unilateral cryptorchidism. However, 22 patients who received HCG had a significantly bigger testis (11.8 mL.) than those treated with primary surgery (9.2 mL). The results showed a significant positive correlation between testicular volume and patient age at treatment. Bilateral cryptorchidism: Location of testis was prescrotal in 34 cases, inguinal in 40 and 6 patients with non-palpable testicles. Mean volume at 18 years was 12.9 mL, greater than unilateral cryptorchid testis (9.7 mL) but smaller than healthy contralateral in unilateral cases (16.2 mL). There were significant differences in the testicular growth for bilateral patients with testicular descent after being treated with HCG (14.4 mL) in respect with those untreated (11.1 mL) or those who underwent primary surgery (11.4 mL). There was a significant positive correlation between the testicular volume and palpable (12.4 mL) or non-palpable testis (10.4 mL). There was a correlation between unilateral or bilateral cryptorchidism and levels of FSH. CONCLUSIONS: Testicular volume and hormonal function at 18 years for patients diagnosed and treated for cryptorchidism during childhood are strongly influenced by whether the undescended testis was unilateral or bilateral. Location of the testes at diagnosis or age of initial treatment exerts no definite effect on testicular volume improvement r hormonal levels at 18 years of age.

Pacientes y métodos: Revisamos las historias de niños con estreñimiento funcional (Roma III) tratados con PEG+E. Administramos el PEG mezclado en el biberón o con líquidos, medio sobre al día en menores de 12 meses y 1 sobre al día en mayores de 12 meses. Registramos la dosis inicial y de mantenimiento eficaz, el número de deposiciones/semana y la consistencia de las heces antes y después del tratamiento, la duración y los efectos secundarios. Resultados: Identificamos 35 pacientes (19 niñas y 16 niños), con una media de edad de 13,64 ± 6,10 meses y un peso medio de 11,65 ± 2,72 kg. La duración media del tratamiento fue de 4,6 ± 3,67 meses. La dosis inicial fue de 0,43 ± 0,26 g/kg/día y la dosis de mantenimiento eficaz de 0,57 ± 0,34 g/kg/día. Observamos diferencias estadísticamente significativas en el número de deposiciones/semana y en la consistencia de las heces antes y después del tratamiento. El PEG resolvió el estreñimiento en 34 pacientes (97,14%) a las 12 semanas de tratamiento. Observamos efectos secundarios en 5 pacientes (14,2%), que se resolvieron al ajustar la dosis. Conclusiones: La aceptación, el cumplimiento y la adherencia al tratamiento fueron muy buenos. La dosis efectiva media fue de 0,57 g/kg/día. La mejoría en el número de deposiciones por semana y en la consistencia de las heces fue muy significativa (p <0,001). Los efectos secundarios se resolvieron al ajustar la dosis. El PEG+E es seguro, bien tolerado y altamente eficaz en el tratamiento del estreñimiento funcional en pacientes menores de 24 meses (AU)

Aim: To evaluate the efficacy, tolerance and optimal dose of PEG 3350 with electrolytes for treatment of functional constipation in patients younger than 24 months. Patients and methods: Reviewed the charts patients with functional constipation (Rome III criteria) treated with PEG orally. PEG was administered mixed in the bottle or diluted in fluids, using 1/2 sachet/day in younger than 12 months and 1 sachet/day in older than 12 months. Initial and effective maintenance dose, number of stools per week and stool consistency before and after treatment, duration and the side effects of treatment were recorded. Results: Thirty-five patients (19 female and 16 male) were identified. Mean age was 13.64 ± 6.10 months, mean weight 11.65 ± 2.72 kg. Mean duration of treatment was 4.6 ± 3.67 months. Mean initial dose was 0.43 ± 0.26 g/kg/day and mean effective maintenance dose was 0.57 ± 0.34 g/kg/day. There was a significant difference in the number of stools per week and in the stool consistency score after treatment (p <0.001). PEG relieved constipation in 97.14% of patients (n= 34) after 12 weeks of treatment. Adverse events included 5 patients (14.2%), resolved after adjusting the dose. Conclusions: Acceptance, compliance and adherence of families to treatment was very good. Average effective dose was 0.57 g/kg/day. There was a significant difference in the number of stools per week and in the stool consistency score before versus after treatment (p <0.001).

Alimentación y enfermedad inflamatoria intestinal. Tratamiento y control nutricional de la EII en pediatría. Parte 2 / Food and inflammatory bowel disease. Treatment and nutritional control in paediatric IBD. Part 2

La relación que se establece entre la enfermedad inflamatoria intestinal (EII) y la dieta es compleja. Las publicaciones sobre este aspecto son escasas y contradictorias, más aún, si cabe, en el ámbito de la pediatría. El presente trabajo, en una primera parte, ofrecía una revisión de la evidencia científica existente sobre el discutible papel de la dieta como factor de riesgo o causa de la aparición de la EII, así como sobre las consecuencias nutricionales que tiene dicha enfermedad en una población en periodo de desarrollo. La segunda parte de la revisión se centra en evaluar la eficacia de la nutrición enteral como tratamiento de la EII, especialmente en la enfermedad de Crohn, y el papel preponderante que en este caso desempeña frente al tratamiento farmacológico, así como su capacidad para revertir las complicaciones derivadas de esta patología en cuanto al estado nutricional y al crecimiento(AU)

The link which exists between inflammatory bowel disease (IBD) and diet is a complex one. Publications on this issue are scarce and contradictory, even more so in the paediatric field. This first paper provided a review of the existing scientific evidence concerning the debatable role of diet as a risk factor or cause of IBD, as well concerning as the nutritional consequences of this disorder for a population at this stage of development. The second part of the review concentrates on assessing the effectiveness of enteral nutrition in treating IBD, especially in cases of Crohn’s disease, and the predominant role it plays in such cases in comparison with pharmacological treatment, as well as its ability to reverse complications arising from this pathology in terms of nutritional status and growth(AU)

Recomendaciones para el tratamiento del estreñimiento funcional / Guidelines for the treatment of functional constipation

El estreñimiento es un problema clínico frecuente. Afecta del 2 al 30% de los niños, según el criterio diagnóstico utilizado. El tratamiento recomendado se basa en: a) explicación-desmitificación; b) desimpactación fecal y c) mantenimiento con cambios en la dieta, modificación de los hábitos higiénicos y el uso de laxantes. En la última década ha variado el sistema de vaciado intestinal; de la clásica vía rectal hemos pasado al uso generalizado de la vía oral a base de polietilenglicol 3350.Se debe tener en cuenta las necesidades individuales y las preferencias del paciente. El tratamiento de mantenimiento se iniciará inmediatamente después de lograr el vaciado intestinal. Está basado en la modificación de los hábitos dietéticos, higiénicos y en el uso de laxantes. Una adecuada ingesta de fibra y agua, el entrenamiento del hábito defecatorio y el uso de laxantes orales logra una defecación diaria y no dolorosa, evitando la reacumulación de heces. El uso de enemas puede ser efectivo para la desimpactación, pero tiene el riesgo de lesión traumática y no es adecuado para el tratamiento de mantenimiento. Los laxantes recomendados son los osmóticos. El tratamiento de primera elección en niños de cualquier edad es el polietilenglicol 3350 por su seguridad, efectividad y tolerancia. Su dosis varia entre 0,25 a 1,5g/kg. El mejor conocimiento de la fisiología de la defecación ha permitido el desarrollo de nuevos fármacos: bloqueantes de los receptores de la serotonina o activadores de los canales del cloro (AU)

Constipation is common in childhood. It can affect around 5–30% of the child population, depending on the criteria used for diagnosis. The currently recommended treatment is based on three main points: a) explanation, b) disimpaction and c) maintenance therapy consisting of diet changes, behavioural modification, and the use of laxatives. In the last decades treatment on disimpaction have changed radically from the rectal route to the oral route with polyethylene glycol 3350 (PEG), the most used and accepted regimen nowadays. Treatment and care should take into account the individual needs and preferences of the patient. Good communication is essential, to allow patients to reach informed decisions about their care. Maintenance therapy consists of dietary interventions, toilet training, and laxatives to obtain daily painless defaecation in order to prevent re-accumulation of stools. Maintenance therapy should be start as soon as the child's bowel is disimpacted. Early intervention with oral laxatives may improve complete resolution of functional constipation. Enemas using phosphate, mineral oil, or normal saline are effective in relieving rectal impaction, but carry the risk of mechanical trauma and are not recommended for maintenance therapy in the paediatric population. Among osmotic agents, polyethylene glycol 3350 plus electrolyte solutions appear to be the first-line drug treatment to use in children of any age, as it is safe, effective, and well-tolerated. Recommended doses ranges from 0.25 to 1.5g/kg. Advances in the understanding of the gastrointestinal enteric nervous system and epithelial function have led to the development of new substances that bind to serotonin receptors or are chloride channel activators (AU)

INTRODUCTION: Actually, the perinatal ovarian cysts are increasingly being diagnosed by prenatal and neonatal ultrasound. OBJECTIVE: We reported our experience in the surgical management of perinatal ovarian cysts. Patients and methods. We have reviewed the clinical charts of 10 female newborns diagnosed of ovarian cysts who underwent surgical management in our hospital from 1989 to 2009. RESULTS: The ovarian cysts were diagnosed antenatally in 8 cases and period neonatal in 2 cases. The clinical presentation was asymptomatic abdominal mass in 7 cases. Ultrasound confirmed the ovarian mass in 8 patients. CT scan and MRI were necessary for confirm suspected diagnosis in two patients. Ultrasonography showed 7 complex cysts and 3 simple cysts. Surgery of the complicated cysts revealed ovarian torsion in 5 cases and 1 hemorragic cyst. At surgery, 5 patients underwent salpingooophorectomy, 2 patients needed oophorectomy and in 3 cases only cystectomy were necessary. CONCLUSION: The ovarian torsion is the most common complication and the cause of loss of the ovary. The neonatal ovarian cysts greater than 5 centimetres, symptomatic cysts, complex cysts and cysts persisting for more than 6 months need surgical intervention.

Laparoscopic complication was one unexpectec opening of common hepatic duct. Concomitant procedures were:9 intraoperative cholangiography, 5 hepatic biopsies, 3 splenectomies,2 appendectomies. The pathologic anatomy showed: chronic lithiasiccholecystitis 30, normal gallbladder 3, chronic cholecystitis 1, gallbladder adenocarcinoma 1, chronic inflammatory changes 2. Conclusions. The main indication of cholecystectomy was thecholelithiasis. The majority were laparoscopic cholecystectomies with shorter operative time and shorter hospital stay. The intraoperative cholangiography, hepatic biopsy and splenectomy were the more frequent concomitant procedures. Main pathologic finding was the chronic lithiasic cholecystitis (AU)

Endoscopia digestiva terapéutica pediátrica en el siglo XXI / Therapeutic pediatric digestive endoscopy in the XXI century

La endoscopia pediátrica se ha trasformado lenta y progresivamente de una técnica puramente diagnóstica en una técnica terapéutica de primer orden. Todo ello gracias a la evolución tecnologíca y a la miniaturización del equipamiento. Estos procedimientos invasivos son realizados con anestesia general, y representan una pequeña intervención quirúrgica, por lo que debe protocolizarse el uso del consentimiento informado. Muchos de ellos son realizados habitualmente en las unidades de endoscopia pediátrica: extracción de cuerpos extraños, dilatación esofágica, gastrostomía endoscópica percutánea, técnicas hemostáticas, polipectomía; para otras técnicas existen pocas indicaciones: esclerosis de varices esofágicas, hemostasia en hemorragia digestiva, achalasia; y otras, por su excepcionalidad, como la colangiopancreatografía endoscópica retrógrada, drenaje de pseudoquistes pancreáticos, son realizadas en colaboración con los endoscopistas de adultos que poseen una mayor experiencia en este campo. La endoscopia terapéutica es una técnica segura, efectiva y posible de realizar en la mayoría de las unidades de endoscopia pediátrica (AU)

With development and improvement of the endoscope equipment, the paediatric endoscopy is developing from the diagnosis endoscopy to the interventional endoscopy. It is realized under general anaesthesia as a minimal invasive surgery and it is necessary to regularize the legal requirements. The main acts are realized in a current way in paediatrics endoscopy units: extraction of foreign body, dilation of oesophageal strictures, haemostatic techniques, gastrostomy, polipectomy. Other indications are less frequent: injection sclerotherapy, haemostasis of upper GI bleeding or endoscopic achalasia treatment. The biliary and/or pancreatic lesions is rare in children, in these cases, interventional endoscopy is usually done with the collaboration of the adult endoscopists, with a far experience. Interventional endoscopy is a safe and effective technique that can be performed in all the pediatrics endoscopy units (AU)

Relevance of herniography for accurate diagnosis of patent processus vaginalis in cryptorchidism.

OBJECTIVE: To clarify the role of peritoneography in assessing the patency of processus vaginalis (PV) in pediatric patients diagnosed with cryptorchidism. MATERIALS AND METHODS: We designed a prospective clinical trial to evaluate the patency of PV in boys presenting cryptorchidism. Herniography was performed in 310 prepubertal boys. Data about the morphology of PV was compared with operative findings in those surgically treated patients. Retractile and ectopic testes were excluded from the study. RESULTS: Of the 376 undescended testes (310 patients), 281 cases were associated with an obliterated PV. Herniography revealed 95 cases of open PV in cryptorchid boys. The 244 normally descended testes had associated patent processus vaginalis in only 31 cases. CONCLUSIONS: Herniography is the most relevant procedure for accurate diagnosis of persistent PV. The persistence of PV was significantly more frequent when the position of the testes is more cranial. The incidence of an open PV decreases with age.
