Guidelines on surgery of the thoracic sympathetic nervous system.

Thoracic sympathetic nervous system (TSNS) surgery has increased in importance in the last few years, generating great expectations among the general population and the scientific community. This has been due to the excellent results obtained by videothoracoscopy-assisted thoracic sympathectomy in the treatment of essential hyperhidrosis and other TSNS disorders. This minimally invasive surgical technique has been shown to be effective, and with a low morbidity it is accepted as one of the best therapeutic options for the treatment of palmar and bilateral axillary hyperhidrosis and the number of patients consulting with the intention of having the operation has increased considerably. Although compensatory sweating, which is occasionally intense, often occurs after the surgery, this and other secondary effects of the technique are well tolerated by patients. The current evidence on TSNS and the treatment of essential hyperhidrosis is based on observational studies, making it difficult to compare series and draw conclusions. There has been much discussion on standardising the technique, defining the most favourable levels for clipping, and choosing the type of denervation with least secondary effects. This has led to the need to draw up these guidelines which should clarify and standardise the criteria for managing patients with disorders of TSNS.

Normativa sobre Cirugía del Sistema Nervioso Simpático Torácico / Guidelines on Surgery of the Thoracic Sympathetic Nervous System

La cirugía del sistema nervioso simpático torácico (SNST) ha experimentado un gran auge en los últimos años, generando gran expectación entre la población general y la comunidad científica. Esto se ha debido a los excelentes resultados que ha obtenido la simpatectomía torácica por videotoracoscopia en el tratamiento de la hiperhidrosis esencial y en otros trastornos del SNST.Esta técnica de cirugía mínimamente invasiva ha demostrado ser efectiva y con baja morbilidad, aceptada como una de las mejores opciones terapéuticas para el tratamiento de la hiperhidrosis palmar y axilar bilateral, viéndose incrementado de manera considerable el número de pacientes que consultan con intención de operarse.Aunque la sudoración compensadora, intensa en ocasiones, aparece con gran frecuencia tras la cirugía, éste y otros efectos secundarios de la técnica son bien tolerados por los pacientes.La evidencia actual respecto a la cirugía del SNST y del tratamiento de la hiperhidrosis esencial se basa en estudios observacionales, haciendo difícil comparar series y extraer conclusiones. Se ha discutido mucho para unificar la técnica, definir los niveles de sección más favorables y elegir el tipo de denervación con menos efectos secundarios. Este hecho crea la necesidad de elaborar esta normativa que clarifique y unifique criterios para el manejo de los pacientes con trastornos del SNST(AU)

Videotoracoscopia exploradora y videopericardioscopia en la estadificación definitiva y valoración de la resecabilidad del cáncer de pulmón / Exploratory Videothoracoscopy and Videopericardioscopy in the Definitive Staging and Assessment of Resectability of Lung Cancer

Introducción: El objetivo del artículo es presentar nuestra experiencia en videotoracoscopia para laestadificación y valoración de la resecabilidad del cáncer de pulmón.Pacientes y métodos: Desde 1993 realizamos videotoracoscopia exploradora (VTE) para la estadificación y valoración de la resecabilidad del cáncer de pulmón. Cuando se sospecha que hay afectación vascularintrapericárdica, la exploración intrapericárdica de los vasos mediante videopericardioscopia (VPC) sirvepara valorar la resecabilidad en estos supuestos cT4. Hasta diciembre de 2007 intervenimos a 1.381pacientes con carcinoma broncogénico. En este grupo de pacientes se realizaron 91 VPC, 45 de ellas por sospecha previa de invasión hiliar y vascular en la tomografía computarizada o resonancia magnética; en los 46 restantes se indicó durante la VTE.Resultados: En 1.277 pacientes pudo llevarse a cabo la VTE, que no fue posible en 104 casos por adherenciaspleurales firmes —61 pudieron resecarse trastoracotomía y sólo 43(3,1%) fueron toracotomíasexploradoras—. En 141 casos (10,2%)se hallaron en la VTE causas de irresecabilidad: en 81 invasiónmediastínica, en 38 carcinomatosis pleural, en 6 concurrieron ambas causas y en 16 había invasióntranscisural y/o vascular que impedía la lobectomía en pacientes que no toleraban la neumonectomía. En 61 de los 91 pacientes a quienes se realizó VPC pudo llevarse a cabo la exéresis pulmonar; en los 30restantes había invasión intrapericárdica que impedía su disección: de la arteria pulmonar en 17 casos; de la arteria y vena pulmonar es superiores en 6; de la arteria pulmonar y vena cava superiores en 2, y ampliainvasión de la aurícula izquierda y venas pulmonares en 5.Conclusiones: La VTE y la VPC como primer paso de la intervención por cáncer de pulmón requiere pocosminutos, no añade morbilidad y evita una significativa proporción de toracotomías exploradoras(AU)

Objective: We present our experience in using videothoracoscopy for the staging and assessment of resectability of lung cancer.Patients and Methods: Since 1993 we have carried out exploratory videothoracoscopy (EVT) for lung cancerstaging and assessment of resectability. When intrapericardial vessel involvemen tissu spected, explorationby videopericardioscopy (VPC)is also useful for assessing resectability in the se cT4 cases. Up to December2007 we had studied 1381 patients with bronchogenic carcinoma. VPC was performed in 91 of these patients. In 45, the procedure was indicated because evidence of hilar and vascular invasion had been observed in the computed tomography or magnetic resonance images. In there maining 46, it wasperformed as a result of EVT findings.Results: We were able to perform EVT in 1277 patients. In 104 cases this procedure could not be performed because of firm pleural adhesions. The tumor was resected after thoracotomy in 61 of these patients;thoracotomy was thus only exploratory in only 43 (3.1%). In 141 cases(10.2%) tumors were consideredunresectable based on EVT, due to mediastinal invasion in 81 cases, pleural carcinoma tos is in 38 cases, and both findings in 6 cases. Lobectomy was ruled out because of spread across a fissure or vascular invasion in16 patients who were unable to tolerate pneumonectomy.In 61 of the 91 patients who underwent VPC we were able to perform lung resection; in the remaining 30, intrapericardial dissection was prevented by invasion of the pulmonary artery (17cases), of the upper pulmonary artery and vein(6cases), of the upper pulmonary artery and superior vena cava (2cases), or ofthe left a trium and pulmonary veins(5cases, in which the invasion was extensive).Conclusions: EVT and VPC as a first stepin lung cancer treatment require only a few minutes, do not contribute to morbidity, and avoid a significant proportion of exploratory thoracotomies(AU)

[Resection of pulmonary metastases in 148 patients: analysis of prognostic factors]. / Cirugía de metástasis pulmonares en 148 pacientes. Análisis de sus factores pronósticos.

OBJECTIVE: To evaluate the prognostic factors for survival in a series of patients who underwent surgery for pulmonary metastases from primary tumors in distinct organs. PATIENTS AND METHODS: This was a retrospective study of 148 patients operated between May 2001 and May 2007. Multivariate analysis was used to evaluate overall survival. Patients scheduled for tumorectomy were included provided their primary tumor was controlled and they had no extrathoracic recurrence and adequate cardiorespiratory function. The influence of the following prognostic factors was analyzed: number and diameter of the metastases, lymph node infiltration, complete resection, and, above all, histological type. A significance level of 95% was used. RESULTS: A total of 90 men (60.81%) and 58 women (39.19%) were operated. The mean (SD) age was 56.5 (9.7) years. The actuarial survival at 6 years was 30.3% (n=45) and the median survival was 34 months. The factors that affected survival were the number of metastases (P< .05), diameter of the lesions (P< .05), lymph node infiltration (P< .05), complete resection (P< .05), and, above all, histological type (P< .05). Tumorectomy was the most commonly performed operation. CONCLUSIONS: These results suggest that, in the absence of other therapeutic options and contraindications, we should operate on patients in whom the primary tumor is controlled and in whom complete resection can be performed. Even if factors associated with poor prognosis are present, the outcomes are always better than when surgery is not performed, particularly in view of the relatively low morbidity and mortality associated with this type of surgery.

OBJETIVO: Evaluar los factores pronósticos de supervivenciaen una serie de pacientes intervenidos por metástasispulmonares de diferentes tumores y órganos.PACIENTES Y MÉTODOS: Se ha realizado un estudio retrospectivode 148 pacientes intervenidos entre mayo de 2001 ymayo de 2007, y se ha aplicado un análisis multivariantepara valorar la supervivencia global. Los criterios de inclusiónfueron: control del tumor primario, sin recurrencia extratorácicay función cardiorrespiratoria suficiente, siemprecon intención de tumorectomía. Se valoró qué influencia teníanen el pronóstico los siguientes factores: número de metástasis,diámetro de éstas, adenopatías invadidas, cirugíacompleta y, sobre todo, tipo histológico, para un nivel de significacióndel 95%.RESULTADOS: En total se intervino a 90 varones (60,81%)y 58 mujeres (39,19%). La edad media ± desviación estándarera de 56,5 ± 9,7 años. Se obtuvo una supervivencia actuariala 6 años del 30,3% (n = 45), con una mediana de supervivenciade 34 meses. Los factores que influyeron en elpronóstico fueron el número de metástasis (p < 0,05), el diámetrode éstas (p < 0,05), la presencia de adenopatías invadidas(p < 0,05), la cirugía completa (p < 0,05) y, sobre todo,el tipo histológico (p < 0,05). La tumorectomía fue la intervenciónmás realizada.CONCLUSIONES: Los resultados avalan que aceptemos paratratamiento quirúrgico a los pacientes sin otra posibilidadterapéutica a quienes pueda realizarse una resección completa,que tengan el tumor primario controlado y no presentenotras contraindicaciones, pues, aunque en presencia deciertos factores empeora la supervivencia, los resultados sonsiempre mejores que con la abstención quirúrgica, máximesi se tienen en cuenta las cifras relativamente bajas de morbilidady mortalidad con este tipo de cirugía

[Resection of 8 mediastinal bronchogenic cysts by video-assisted thoracoscopy]. / Quiste broncogénico de mediastino. Resección videotoracoscópica en 8 casos.

Mediastinal bronchogenic cysts are an uncommon entity and surgical experience of their removal by video-assisted thoracoscopy is limited. We present our patient outcomes and surgical technique in the treatment of bronchogenic cysts by video-assisted thoracoscopy. The study included 8 patients (4 females and 4 males between the ages of 4 and 52 years), 7 of whom presented clinical symptoms. The mean widest diameter of the cyst was 7.6 cm. In 5 patients the cyst was in the middle mediastinum and in 3, the posterior mediastinum. The intervention was performed using 3 or 4 entry points. Initial puncture of the cyst and removal of its contents greatly facilitated cyst manipulation and subsequent dissection of the cyst sac from the structures to which it was attached. In all 8 cases resection by video-assisted thoracoscopy was carried out with no intraoperative complications. The mean postoperative hospital stay was 3.3 days. During follow-up, which ranged from 4 months to 10 years, no patients presented late-onset or recurrent complications.

El quiste broncogénico de mediastino es una entidad poco frecuente y la experiencia quirúrgica de su extirpación por videotoracoscopia es limitada. Presentamos nuestros resultados y técnica quirúrgica en el tratamiento de los quistes broncogénicos por videotoracoscopia. El estudio incluye a 8 pacientes (4 mujeres y 4 varones, con un rango de edad comprendido entre los 4 y los 52 los años), de los que 7 presentaban síntomas clínicos. El tamaño medio del quiste en su diámetro mayor era de 7,6 cm. En 5 pacientes se localizaba en el mediastino medio y en 3 en el posterior. La intervención se realiza a través de 3-4 puertas de entrada, y la apertura y el vaciamiento del contenido del quiste desde el inicio constituye una maniobra que facilita enormemente la manipulación y posterior disección del saco quístico de las estructuras a las que se encuentra adherido. En los 8 casos se realizó la resección por videotoracoscopia sin complicaciones intraoperatorias. La estancia media postoperatoria fue de 3,3 días. Los pacientes no han presentado complicaciones tardías ni recidivas durante el seguimiento, que oscila entre los 4 meses y los 10 años

Usefulness of videothoracoscopic intrapericardial examination of pulmonary vessels to identify resectable clinical T4 lung cancer.

BACKGROUND: Discrepancies in predicting resectability by imaging techniques (computed tomography and magnetic resonance imaging) compared with actual intraoperative findings have persuaded us to perform systematic exploratory videothoracoscopy (EVT) as the first step in the surgical evaluation of patients with lung cancer. Resectability of centrally located primary tumors with intrapericardial extension (clinical T4), however, can be established only by direct examination of the pericardial sac contents. Therefore, in these instances, videopericardioscopy (VPC) has been added to our protocol. METHODS: From April 1993 to December 2000, members of our department used EVT to assess 620 patients with lung cancer. Of them, 27 patients, 25 men and 2 women, were seen with pericardial tumor extension. The mean age of the group was 62 years (range, 41 to 77 years). To be properly evaluated, these patients underwent VPC. We used three and, occasionally, four incisions to perform EVT. The same incisions were used to enter the pericardial cavity during VPC. RESULTS: In 15 of the 27 patients, hilar and vascular invasion was correctly predicted by imaging techniques. The other 12, however, were correctly staged only during EVT. The tumor was deemed unresectable by VPC in 6 patients (5 with invasion at the origin of the pulmonary artery and 1 with involvement of the left inferior pulmonary vein and left atrium), and exploratory thoracotomy was obviated. There was no morbidity or mortality in these 6 patients, and their mean length of hospital stay was 48 hours. The remaining 21 patients underwent thoracotomy and intrapericardial lung resection. Six of them had been considered to have unresectable disease on the basis of computed tomographic findings or magnetic resonance imaging studies. An average of 22 minutes (range, 16 to 33 minutes) was added to the operation when VPC was used. CONCLUSIONS: This study suggests that EVT is superior to imaging techniques (computed tomography or magnetic resonance imaging) in detecting tumor extension into the pericardium. In addition, short of an exploratory thoracotomy, VPC seems to be the most definitive study to establish resectability of centrally located tumors with pericardial invasion. Unnecessary exploratory thoracotomies can thus be avoided.
