Thoracoscopic pneumonectomy in a 4 year-old-child with destroyed lung following viral pneumonia. / Tiroidectomía transoral endoscópica con abordaje vestibular (TOETVA): una nueva opción para el tratamiento de pacientes pediátricos.

Pediatric pneumonectomies are exceptional nowadays, being reserved for cases with destroyed lungs with frequent exacerbations and reinfections and only two cases of thoracoscopic pneumonectomy have been previously published. We present the case of a 4-year-old patient with no relevant history who developed complete atelectasis of the left lung (LL) after influenza A pneumonia, followed by secondary recurrent infections. A year later a diagnostic bronchoscopy without alterations was performed. A complete loss of volume and hypoperfusion of the LL (right lung perfusion 95%, LL perfusion: 5%) with bronchiectasis and hyperinsufflation and herniation of the right lung into the left hemithorax was observed in a pulmonary perfusion SPECT-CT. After unsuccessful conservative management and recurrent infections a pneumonectomy was indicated. The pneumonectomy was performed through a five-port thoracoscopy. The dissection of the hilum was made using hook electrocautery and sealing device. The left main bronchus was sectioned with an endostapler. There were no intraoperative complications. An endothoracic drain was removed the first postoperative day. The patient was discharged on the fourth postoperative day. The patient has not presented any complications 10 months after surgery. Although pneumonectomy is an exceptional surgery in children, it can be performed by minimally invasive surgery with success and safety in centers with extensive experience in pediatric thoracoscopic surgery.

Hoy en día, las neumonectomías pediátricas son algo excepcional. El procedimiento se reserva para aquellos casos en los que los pulmones están destruidos y presentan exacerbaciones y reinfecciones frecuentes, con tan solo dos casos de neumonectomía toracoscópica publicados hasta la fecha. Presentamos el caso de un paciente de 4 años sin antecedentes de interés que desarrolló atelectasia completa del pulmón izquierdo (PI) tras neumonía por gripe A, seguido de infecciones secundarias recurrentes. Un año después, se le practicó broncoscopia diagnóstica, sin que esta mostrara alteraciones significativas. Tras realizársele un SPECT-CT de perfusión pulmonar, se evidenció pérdida completa de volumen e hipoperfusión del PI (perfusión del pulmón derecho: 95%; perfusión del pulmón izquierdo: 5%), con bronquiectasia e hiperinsuflación y herniación del pulmón derecho hacia el hemitórax izquierdo. Tras fracasar el manejo conservador y registrarse infecciones recurrentes, se estableció la indicación de neumonectomía. La neumonectomía se llevó a cabo mediante toracoscopia por cinco puertos. La disección del hilio se realizó mediante gancho de electrocoagulación y dispositivo de sellado. El bronquio principal izquierdo se seccionó con endograpadora. No se registraron complicaciones intraoperatorias. El drenaje endotorácico se retiró al día siguiente de la intervención, mientras que el paciente fue dado de alta a los cuatro días, sin que haya presentado complicaciones transcurridos 10 meses desde la cirugía. Aunque la neumonectomía es una intervención excepcional en niños, puede llevarse a cabo de manera exitosa y segura por cirugía mínimamente invasiva en centros con amplia experiencia en cirugía toracoscópica pediátrica.

[Role of laparoscopy in premature infants with suspicion of necrotizing enterocolitis]. / Papel de la laparoscopia en prematuros con sospecha de enterocolitis necrotizante.

INTRODUCTION: The indication of surgery in necrotizing enterocolitis (NEC) can be difficult in the absence of pneumoperitoneum or peritonitis. We propose laparoscopy for early diagnosis of intestinal perforation or necrosis in order to avoid unneccessary laparotomies. MATERIAL AND METHODS: A new protocol was proposed which included diagnostic and therapeutic laparoscopy in cases of uncertain surgical ECN indication. Subsequently, a prospective study of the 7 patients who underwent laparoscopy was performed, analyzing pathophysiological effects in the premature, technical difficulties of the procedure, and postoperative diagnostic consistency. RESULTS: The mean gestational age at birth was 27 weeks (range 25 to 31) with an average weight of 1.147 kg (range 0.900 to 1.600) two trocars were placed as the focal oriented scanning or radiography, using a pneumoperitoneum 6-10 mmHg for an average of 17 min. Laparoscopy avoided laparotomy in a patient who did well after washing and drainage and magnified lesions in one patient who did not require laparotomy after intestinal bypass. In other cases, laparoscopy was followed by minilaparotomy oriented to the lesions and stoma formation. There were no surgical complications attributable to the procedure, which was well tolerated in all cases. CONCLUSIONS: Laparoscopy can be a useful tool for evaluation of lesions of NEC in cases of uncertain surgical indications. In our experience, it is well tolerated in neonates of low weight, allowing oriented minilaparotomies or even to avoid laparotomy.

[Management endourologic of pyeloureteral junction stenosis]. / Tratamiento endourológico de la estenosis pieloureteral congénita.

OBJECTIVES: To report our experience with endourologic methods in the treatment of pyeloureteral stenosis in children. MATERIALS AND METHODS: From July 2004, 7 patients from 9 months to 15 years old with pyeloureteral junction stenosis (PUJ) diagnosis underwent endourologic repair. An endourological dilatation was made under radioscopic control. The procedures consist of an initial cystoscopy with a retrograde placement of catheter (4 or 5 Fr) and the guide wire (0,014''-or 0,035''). The high pressure balloon (3 to 5 Fr) was then railroad over the wire and positioned across the stenosis for dilatation. A double J stent (3 to 6 Fr) was then introduced, remaining it during 6 weeks. RESULTS: There was no intraoperative complications. Median inhospital stay was 2 days (range, 2 to 8). The double J stent was removed without complications. All patients are asymptomatic with improvement in excretion times (MAG3 renography) and antero-posterior renal pelvis diameter (ultrasound measurement). CONCLUSIONS: Balloon dilatation is a viable option in the management of PUJ obstruction even in children under one year old, with minimal morbidity.

[The paraurethral cyst or Skene's duct cyst in the female newborn]. / Quiste parauretral de Skene en niña recién nacida.

The paraurethral cyst or Skene's duct cyst is a rare congenital anomaly in the female newborn. It appears like a round, yellow or orange-colored cystic mass on either side of the urethral meatus. The reported incidence is 1 in 2.000 to 7.000 female births. The low frequency of the Skene's duct cyst and the little awareness of it and its benignity may lead to wrong diagnosis that underestimates its incidence. There are authors that agree with surgical treatment of paraurethral cyst to obtain an early resolution, even though a majority agrees to manage conservatively.
