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.

Abdominal cystic lymphangiomas in pediatrics: surgical approach and outcomes.

BACKGROUND: Abdominal Cystic lymphangiomas (ACL) are uncommon benign masses usually presented during infancy. Although extremely rare, they may cause complications; therefore, the recommended therapy is surgical excision. The purpose of this study is to report our experience with the diagnosis and surgical treatment of ACL in pediatric population. MATERIAL AND METHODS: From January 1994 to December 2009, 10 patients (6 females; 4 males) with diagnostic confirmation of ACL were retrospectively included in study. Children's age ranged between 9 months and 8 years (mean age at diagnosis was 2.5 years). Clinical presentation, cyst location, imaging studies employed, surgical approach and pathologic features were analyzed. RESULTS: The most common symptom was abdominal pain but three cases were incidentally detected. One case had presented with acute abdomen after traumatic haemorrhage of the tumor. All patients were diagnosed with ultrasonography as first-line radiological study. MRI was used in last three cases. At surgery, concomitant bowel resection was necessary in 3 children. Location of the lesion (omentum, mesentery) did not influence the outcome but surgery was more difficult (operative time over three hours) in patients with lymphangioma affecting mesentery of the jejunum. Mean hospital stay after surgery was 6.7 days. Mean follow-up was 5.1 years. No recurrence of the cystic lymphangioma was noticed during follow-up. One case developed an intestinal occlusion due to bowel adhesions 1 year after surgery. CONCLUSIONS: ACL usually affect infants and young children and may present with spectrum of symptoms from an incidental finding to an acute life-threatening abdominal obstruction. Complete excision of the tumor is a safe and effective method in the management of ACL in pediatric population. Surgery is mandatory to avoid potential complications.

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.

Endobronchial tuberculous granuloma in children.

Endobronchial tuberculosis is rare in children, in whom it is usually a complication of primary tuberculosis. Endobronchial involvement may adopt several forms, with granuloma being infrequent. Here we report on 10 cases of endobronchial tuberculous granuloma diagnosed and treated in our Paediatric Surgery Service between 1991 and 2004. In 2 cases the presentation was acute and constituted the first manifestation of TB; the remaining patients were undergoing treatment or had been treated for primary TB, and presented with clinical symptoms or radiological signs that led us to suspect endobronchial involvement. In all cases the granuloma was removed by bronchoscopy. Patients received conventional medical TB treatment, with corticoids for 4 weeks following granuloma removal. The clinical course was favourable in all cases and on follow-up we saw no complications. Endobronchial tuberculous granuloma should be borne in mind in children with symptoms or signs of airway obstruction and especially during the course of tuberculosis treatment.
