RESUMO
This is a case report of a patient with vulvar condyloma acuminatum associated with hyperkeratosis and folliculitis, which had been refractory to two previous therapies. The patient had been successfully treated using a combination of promising techniques: the ultrasonic scalpel and MAL photodynamic therapy.

BACKGROUND AND OBJECTIVES: The ultrasonically activated scalpel is a surgical instrument that is used in minimally invasive surgery to safely cut and seal vessels. This study reported the experimental observations of the use of a laparoscopic ultrasonic scalpel, including its safety and feasibility. in sealing vessels of different diameters in an in vivo animal model during both physiological and supraphysiological blood pressure (BP) conditions. METHODS: One healthy female swine was used. We performed resections of the omentum, biopsies in different regions of the liver, and a hysterectomy. Vessels with diameters ranging from 2 to 10 mm were sealed with the ultrasonic scalpel under regular hemodynamic conditions and during pharmacologically induced arterial hypertension (BP challenge). RESULTS: For 10 random cuts made in the omentum and during the hysterectomy, the ultrasonic scalpel was effective and fast, with no immediate or delayed bleeding. Bipolar energy, sutures, and hemoclips were not required to control bleeding. No bleeding was observed in sealed vessels up to 8 mm, even during BP challenges sustained for longer than 5 minutes. When testing vessels of 10 mm, bleeding occurred in 1 common iliac vein before 10 minutes of waiting (the point of bleeding was easily identified) and bleeding occurred in 1 of the common iliac arteries during the BP challenge. CONCLUSION: Our findings corroborate that the ultrasonic scalpel can safely seal arteries up to 8 mm in diameter to prevent or control bleeding during laparoscopic procedures, even when BP exceeds normal levels.

Introduction: Surgery of the thyroid gland is the most performed procedure by the endocrine surgeon. In the last years, new techniques have been incorporated in this procedure. Our objective is to analyse the impact of these techniques in our department. Methods: We performed a retrospective and comparative study among three samples of patients submitted for total thyroidectomy. Group I: Sample of 96 patients operated between 2004 and 2007 performing total thyroidectomy. In this period we didn't use ultrasonic scalpel (US) nor intraoperative neuromonitoring (INM). Group II: Sample of 108 patients operated between 2008 and 2010. In this group we used US for hemostasis. Group III: Sample of 82 patients operated between 2011 and 2012. In this group we used both US and INM. The groups are compared: complications, postoperative stay, surgical time and costs per patient. Results: We analysed the following complications: haemorrhage, postoperative hipocalcemia and recurrent nerve palsy. We didn't find significant differences among the samples of patients but there were a less percentage of recurrent palsy in the third group (4.9 percent vs 12.5 and 11.1 percent). We found significant differences when stay, surgical time and costs were analysed. Conclusion: The use of new techniques in thyroid surgery has supposed an improvement not only in the clinic outcomes but in the surgical time.
Objetivo: La cirugía de la glándula tiroides representa el procedimiento más frecuente que realiza el cirujano endocrino. En los últimos años se han ido incorporando nuevas técnicas aplicadas a este procedimiento. El objetivo de nuestro trabajo es analizar el impacto que dichas técnicas han tenido en nuestro servicio. Material y Métodos: Estudio retrospectivo y comparativo entre tres muestras de pacientes a los que se realizó tiroidectomía total. Grupo I: Muestra de 96 pacientes intervenidos entre 2004 y 2007 a los que se realizó tiroidectomía total. En este período no se utilizó bisturí ultrasónico (BU) ni neuromonitorización intraoperatoria (NMI). Grupo II: Muestra de 108 pacientes intervenidos entre 2008 y 2010. En este grupo se realizó hemostasia con BU. Grupo III: Muestra de 82 pacientes intervenidos entre 2011 y 2012. Se utilizó tanto el BU como la NMI. Se comparan los grupos en cuanto a: complicaciones, estancia postoperatoria, tiempo quirúrgico y coste por paciente. Resultados: Las complicaciones analizadas fueron: hemorragia, hipocalcemia postoperatoria y parálisis del nervio laríngeo recurrente. No encontramos diferencias significativas entre los grupos aunque sí hay una menor tasa de parálisis recurrenciales en el tercer período (4,9 por ciento vs 12,5 y 11,1 por ciento). Hemos obtenido diferencias significativas en estancia, tiempo quirúrgico y coste por paciente. Conclusión: La inclusión de las nuevas técnicas en cirugía tiroidea ha supuesto una mejora en los resultados clínicos así como un ahorro de tiempo de quirófano.

Introducción. El diagnóstico de la enfermedad pulmonar intersticial en la infancia constituye un reto. La biopsia pulmonar a cielo abierto se ha considerado el mejor procedimiento para obtener tejido pulmonar en niños; sin embargo, la biopsia con toracoscopia puede ser igualmente eficaz y menos agresiva. El objetivo de este trabajo fue analizar los resultados del empleo del bisturí ultrasónico con tres trocares de 5 mm (uno para toracoscopio y dos puertos más de trabajo) para la toma de biopsias pulmonares por toracoscopia. Métodos. Se analizó, retrospectivamente, una serie de casos de niños a quienes se les tomaron biopsias pulmonares mediante toracoscopia, utilizando tres puertos de trabajo y el bisturí ultrasónico, durante el periodo comprendido de enero de 2011 a enero de 2012 en un hospital pediátrico de tercer nivel de atención. Resultados. Se registraron cinco pacientes con edades desde uno hasta 13 años. No se presentaron complicaciones durante el transoperatorio o postquirúrgicas en ningún caso. Al revisar los reportes histopatológicos, se encontró suficiente muestra en todos los casos. El sangrado transquirúrgico fue de 4.3 ml en promedio (de 0.5 a 10 ml). El tiempo quirúrgico varió de 2 a 3 horas. Dos casos ameritaron sondas pleurales, las cuales se retiraron a los dos o tres días después del evento quirúrgico, momento en que se dieron de alta del servicio sin complicaciones. Conclusiones. Se corroboró la factibilidad y la seguridad de una técnica para la toma de muestras mediante el uso del bisturí ultrasónico. Esta técnica es fácilmente reproducible en cualquier centro hospitalario que cuente con el recurso para realizar toracoscopias.
Background. Diagnosis of interstitial lung disease (ILD) in children is challenging. Open lung biopsy was long considered to be the best procedure to obtain lung tissue in children. Thoracoscopic biopsy may be equally effective and less aggressive. In this report we analyze the results of the use of ultrasonic scalpel with the placement of three 5-mm trocars (one for thoracoscope and two working ports) for lung biopsy through thoracoscopy. Methods. We present a retrospective case series of children undergoing lung biopsy through thoracoscopy using three working ports and ultrasonic scalpel. The study was carried out from January 2011 to January 2012 in a third-level pediatric hospital. Results. A total of five patients aged 1 to 13 years were included. There were no complications in the five cases analyzed. The sample obtained was sufficient in all cases for histopathological study. During surgery, bleeding was reported on average of 4.3 ml (range: 0.5-10 ml). Operative time ranged from 2 to 3 h. Two cases required chest tube placement. These were removed 2 to 3 days after the surgical event, and patients were discharged without complications. Conclusions. Feasibility is confirmed of a technique for lung biopsy using an ultrasonic scalpel, which is easily reproducible in any hospital with the necessary resources to perform thoracoscopy. In this series there were no complications, bleeding was low and there was opportune placement of transpleural chest tube.
