ABSTRACT
Abstract BACKGROUND: Primary hyperhidrosis is a condition characterized by excessive sweating, inconsistent with the needs for thermoregulation. OBJECTIVE: To assess the effectiveness and the change in the quality of life of patients undergoing bilateral VATS (video-assisted thoracoscopic sympathectomy) for treatment of hyperhidrosis, in a large case series. DESIGN AND SETTING: Cohort study conducted in a tertiary hospital specializing in hyperhidrosis located in São Paulo, Brazil. METHODS: A total of 2,431 patients who underwent surgery consisting of bilateral video-assisted thoracoscopic sympathectomy between January 2000 and February 2017 were retrospectively assessed in an outpatient clinic specializing in hyperhidrosis. The patients underwent clinical and quality of life assessments on two occasions: firstly, prior to surgery, and subsequently, one month after the operation. The presence or absence of compensatory hyperhidrosis (CH) and general satisfaction after the first postoperative month were also evaluated. RESULTS: All the patients operated had poor or very poor quality of life before surgery. In the postoperative period, an improvement in the quality of life was observed in more than 90% of the patients. Only 10.7% of the patients did not present CH, and severe CH occurred in 22.1% of the patients in this sample. CONCLUSION: Bilateral VATS is a therapeutic method that decreases the degree of sweating more than 90% of patients with palmar and axillary hyperhidrosis. It improves the quality of life for more than 90% of the patients, at the expense of development of CH in approximately 90% of the patients, but not intensely.

Abstract Despite the current availability of safe and efficient drugs for treating hypertension, a substantial number of patients are drug-resistant hypertensives. Aiming this condition, a relatively new approach named catheter-based renal denervation was developed. We have now a clinically relevant time window to review the efficacy of renal denervation for treating this form of hypertension. This short review addresses the physiological contribution of renal sympathetic nerves for blood pressure control and discusses the pros and cons of renal denervation procedure for the treatment of resistant hypertension.
Resumo Em que pese a atual disponibilidade de medicamentos seguros e eficientes para o tratamento da hipertensão, um número significativo de pacientes sofre de hipertensão arterial resistente a tratamento medicamentoso. Em vista dessa condição, foi desenvolvida uma abordagem relativamente nova, denominada denervação renal por cateter. Dispomos atualmente de uma janela de tempo clinicamente relevante para analisar a eficácia da denervação renal no tratamento dessa modalidade de hipertensão. A presente revisão aborda a contribuição fisiológica dos nervos renais simpáticos no controle da pressão arterial e discute os prós e contras do procedimento de denervação renal no tratamento da hipertensão resistente.

RESUMO A simpatectomia toracoscópica mostrou-se eficaz no alívio da hiperidrose em diversos pacientes, com melhora da qualidade de vida. O conhecimento do quadro clínico de cada paciente, assim como, as possíveis complicações pós-operatórias, são fundamentais para a obtenção de bons resultados. Deste modo, foi realizada uma revisão na base de dados PubMed de artigos publicados entre 2005 e 2019 que apresentavam como temática principal a simpatectomia realizada por videotoracoscopia para o tratamento da hiperidrose, com o objetivo de avaliar o atual estado da arte referente à qualidade de vida pós-operatória, o tempo de cirurgia e as suas complicações. A partir desta análise, verificou-se a importância do nível de secção da cadeia ganglionar simpática em relação aos resultados. As complicações, apesar de ocorrerem, não reduziram o nível de satisfação e qualidade de vida pós-operatória dos pacientes.
ABSTRACT. Thoracic sympathectomy has been effective in relieving hyperhidrosis in several patients, with quality of life improvement. The knowledge of the clinical picture of each patient, as well as the possible postoperative complications, are fundamental to obtain good results. Thus, we performed a review of articles from the PubMed database published between 2005 and 2019 that presented, as the main topic, thoracoscopy sympathectomy for the treatment of hyperhidrosis, with the objective of evaluating the current state of art referring to postoperative quality of life, surgical time and its complications. From this analysis, we verified the importance of the level of sympathetic ganglion chain section in relation to results. The complication, although occurring, did not reduced the postoperative level of satisfaction or patients' quality of life.

Introdução: Resultados de 3 anos do Symplicity HTN-1 mostraram superioridade da denervação simpática renal percutânea comparada à terapia medicamentosa em hipertensos resistentes. Entretanto, os desfechos de eficácia da denervação simpática renal percutânea no Symplicity HTN-3, primeiro ensaio controlado com procedimento simulado, não foram alcançados. Nosso objetivo foi relatar os resultados de segurança e de eficácia da denervação simpática renal percutânea utilizando o cateter de ablação por radiofrequência de ponta irrigada em hipertensos resistentes. Métodos: Vinte e um pacientes foram submetidos ao procedimento desde julho 2012, dentre eles nove com seguimento ≥ 12 meses, os quais foram incluídos nesta análise. O desfecho primário foi a segurança, avaliada por eventos adversos peri-procedimento, função renal e anormalidade vascular renal aos 6 meses. Os desfechos secundários incluíram mudanças na pressão arterial obtida no consultório e no número de anti-hipertensivos aos 12 meses. Resultados: A média de idades foi 48,8 ± 11,7 anos. No primeiro caso, houve dissecção de artéria renal causada por trauma da bainha. Nenhum caso de trombose, infarto renal ou óbito foi observado. Não se constatou elevação dos níveis séricos de creatinina durante o seguimento. Aos 6 meses, diagnosticou-se um caso de estenose significativa de artéria renal, sem repercussão clínica. A redução média da pressão arterial no consultório foi de 41,1 ± 33,2/18,6 ± 15,2 mmHg (p = 0,04 para pressão arterial sistólica e p = 0,08 para pressão arterial diastólica) e houve redução de 2,0 ± 2,3 no número de anti-hipertensivos aos 12 meses (p = 0,03). Conclusões: A denervação simpática renal percutânea, utilizando o cateter de ablação por radiofrequência de ponta irrigada, mostrou ser factível, segura e eficaz.
Background: The 3-year results of the Symplicity HTN-1 trial have shown the superiority of renal sympathetic denervation over drug treatment in patients with resistant hypertension. However, the efficacy of renal sympathetic denervation was not confirmed by Symplicity HTN-3, the first sham-controlled study. Our objective was to report the safety and efficacy of renal sympathetic denervation using the irrigated radiofrequency ablation catheter in patients with resistant hypertension. Methods: Twenty-one patients were submitted to the procedure since July 2012, nine of them had a follow-up ≥ 12 months and were included in this analysis. The primary endpoint was safety, evaluated by periprocedural adverse events, renal function and renal vascular abnormalities at 6 months. Secondary endpoints included changes in blood pressure obtained in office and in the number of anti-hypertensive drugs at 12 months. Results: Mean age was 48.8 ± 11.7 years. In the first case, there was a renal artery dissection caused by the vascular sheath. There were no cases of thrombosis, renal infarction or death. Serum creatinine levels did not increase during the follow-up period. At 6 months, one case of significant renal stenosis without clinical impact was diagnosed. The average reduction in office blood pressure was 41.1 ± 33.2/18.6 ± 15.2 mmHg (p = 0.04 for systolic blood pressure and p = 0.08 for diastolic blood pressure) and there was a mean reduction of 2.0 ± 2.3 in the number of anti-hypertensive drugs at 12 months (p = 0.03). Conclusions: Renal sympathetic denervation using the irrigated radiofrequency ablation catheter proved to be feasible, safe and effective.

Background: Hypertension [HTN] results in structural and functional cardiac changes which increase cardiovascular morbidity and mortality. The effect of renal denervation [RD] on left ventricular hypertrophy [LVH] and left ventricular [LV] diastolic function is still unclear
Objective: This study investigated the effect of catheter-based renal sympathetic denervation on LVH and diastolic function in patients with resistant hypertension
Methods: We evaluated systolic and diastolic blood pressure [SBP and DBP, LV size, mass and diastolic function before and 6 months after RD in 68 patients with resistant hypertension by transthoracic echocardiography and Doppler
Results: SBP and DBP reduced 6 months after RD [-22 +/- 3 mmHg and -10 +/- 12mmHg; P<0.0001 respectively] LV mass index decreased similarly independent on BP response [-19.37 +/- 2.6 gm/m[2]: P<0.0001]. Diastolic parameters E/A ratio, E-wave deceleration time and intra-ventricular relaxation time improved similarly in all patients after 6 months [0.89 +/- 0.04; P=0.001, -24.85 +/- 8.93 ms; P=0.007 and -6.97 +/- 2.57 ms; P=0.012 respectively]
Conclusion: In patients with resistant hypertension and beside blood pressure lowering effect, renal denervation improves left ventricular hypertrophy and diastolic function. The relation of BP reduction effect and the improvement of cardiac hypertrophy and systolic function suggests a direct effect of sympathetic activity on LV remodeling and function which needs to be confirmed in larger prospective cohorts

PURPOSE: To study the macro and microscopic evaluation of the damage caused by clamping or section of cervical sympathetic nerve in rabbits, quantifying the collagen in the lesions. METHODS: Twenty rabbits were divided into two groups of ten, doing in group 1 (section) section of the right cervical sympathetic nerve, while in group 2 (clipping) clipping of the nerve. All rabbits were induced to death on the seventh day after surgery. The macroscopic variables were: consequences of nerve lesion, clip appearance, presence of infection and adhesions around the nerve. Microscopy used hematoxylin-eosin staining to evaluate the stages and the degree of inflammation and necrosis, and F3BA Picrosirius red staining to quantify collagen. Mann-Whitney test was used for comparisons of collagen types I and III between groups. Fisher exact test analyzed the macroscopic variables, the degree of inflammation and necrosis. RESULTS: There was no discontinuity of nerve injury in the clipping group, as well as the clip was closed in all animals. The presence of severe adhesions was significantly higher in the clipping group (p<0.05). There was no significant difference on other variables macroscopically analyzed. There was no significant difference between groups regarding the type of inflammatory process and its intensity, as well as the presence of necrosis and collagen deposition in the nerves. CONCLUSIONS: In the macroscopic evaluation, the section caused discontinuity, which did not occur in the clamping group; there was no development of local infection; the clipping of the cervical sympathetic nerve was linked to the presence of a greater number of adhesions in comparison to the section group. Microscopically, no difference existed in relation to the type and intensity of inflammation reaction between the groups; occurred predominance of chronic and severe inflammation on the specimens; the necrosis was noticed equally in both groups; there was predominance of type I collagen deposition in relation to type III in both groups.
OBJETIVO: Estudar a lesão provocada pela secção e pela clipagem no nervo simpático cervical de coelhos, avaliando-se a macroscopia, microscopia e quantificando-se o colágeno nas lesões. MÉTODOS: Foram utilizados 20 coelhos, distribuídos em dois grupos de dez, sendo nos animais do grupo 1 (secção) realizada secção do nervo simpático cervical direito, enquanto nos do grupo 2 (clipagem) realizada a clipagem desse nervo. Todos os coelhos foram induzidos à morte no sétimo dia de pós-operatório. As variáveis macroscópicas avaliadas foram: presença de lesão de descontinuidade do nervo, aspecto do clipe, presença de infecção e de aderências ao redor do nervo. A microscopia com hematoxilina-eosina foi feita para avaliar as fases, o grau do processo inflamatório e a presença de necrose; a coloração de Picrosirius red F3BA quantificou o colágeno. Utilizou-se o teste de Mann-Whitney nas comparações dos colágenos tipo I e tipo III entre os grupos. As variáveis macroscópicas, o grau do processo inflamatório e presença de necrose foram analisadas pelo teste de Fisher. RESULTADOS: Não houve lesão de descontinuidade do nervo no grupo clipagem, assim como o clipe encontrou-se fechado em todos os animais desse grupo. A presença de aderências intensas foi significativamente maior no grupo clipagem (p<0,05). Não houve diferença significativa quanto às demais variáveis analisadas macroscopicamente. Não houve diferença significativa entre os grupos quanto ao tipo de processo inflamatório e sua intensidade, assim como quanto à presença de necrose e ao depósito de colágeno nos nervos. CONCLUSÕES: Na avaliação macroscópica, a secção causou lesão de descontinuidade, o que não ocorreu na clipagem; não houve desenvolvimento de infecção local; a clipagem do nervo simpático cervical foi associada à presença de maior quantidade de aderências em relação à secção. Na avaliação microscópica reconheceu-se não haver diferença no tipo e na intensidade do processo inflamatório entre os grupos; ocorreu predomínio de processo inflamatório crônico e acentuado; as necroses ocorreram igualmente em ambos os grupos; houve predomínio de depósito de colágeno tipo I em relação ao tipo III em ambos os grupos.

INTRODUÇÃO: A simpatectomia é o tratamento de escolha para hiperidrose localizada primária. A evolução da técnica visa à melhora dos resultados operatórios e à minimização dos efeitos colaterais, sendo o principal deles o suor reflexo. Esse suor reflexo pode afetar a satisfação em longo prazo, e pode variar conforme as estações do ano, juntamente com a satisfação dos pacientes com os resultados da operação. No entanto, não há dados objetivos quanto ao efeito da sazonalidade sobre os resultados operatórios e sobre os fatores relacionados à satisfação. Os objetivos do presente estudo são: avaliação da variabilidade sazonal sobre o grau das resoluções da sudorese palmar e plantar, bem como a incidência e a intensidade do suor reflexo e análise da influência desses fatores sobre a satisfação; avaliação da dor como fator relacionado à satisfação imediata; avaliação da segurança dos métodos de expansão pulmonar pós-operatória com e sem drenagem pleural e relação dos mesmos à dor. MÉTODOS: Estudo clínico, prospectivo, em duas fases. A primeira, para avaliação de fatores imediatos relacionados à satisfação (fatores antropométricos, dor, presença e intensidade do suor reflexo, grau de resolução da sudorese palma r e plantar, época do ano em que a simpatectomia foi realizada) e segurança dos métodos de expansão pulmonar, cujo desenho é prospectivo, aleatorizado e cego. A segunda, para as avaliações tardias e sazonais dos fatores relacionados à satisfação (fatores antropométricos, presença e intensidade do suor reflexo, grau de resolução da sudorese palmar e plantar), possui desenho prospectivo de coorte. Foram eleitos para o estudo pacientes com hiperidrose palmo-plantar primária submetidos à simpatectomia torácica videoassistida; o período de inclusão foi de 16 meses e o seguimento médio final de 623,63 ± 15,13 dias...
INTRODUCTION: Sympathectomy is the treatment of choice for primary and localized hyperhidrosis. Efforts in evolution of this technique have the aim to improve the surgical results and minimizing the collateral effects, witch told to be the sudomotor reflex. This sudomotor reflex could influence the long term satisfaction; it also could change between the seasons of the year, as well as the satisfaction could change in this matter. However, there is no objective data regarding the influence of the seasonality over the surgical results and satisfaction. The objectives of this study is to assess the seasonal variability of palmar and plantar resolution, as well as the incidence of sudomotor reflex and its intensity; to correlate this factors with satisfaction. To evaluate the pain as a factor related to immediate satisfaction; to assess the safety of lung expansion methods and relate this with postoperative pain. METHODS: A two stage prospective clinical assay. The first stage consists of assessment of the immediate factors related to satisfaction (anthropometrics factors, pain, presence and intensity of the sudomotor reflex, palmar and plantar resolutions, season of the year in witch the operation was performed) and the safety of lung expansion methods; it is a prospective, randomized and blinded study. The second stage is a cohort study, assessing the late factors related to satisfaction (anthropometrics factors, presence and intensity of the sudomotor reflex and palmar and plantar resolutions), under distinct climatic situations. There were included patients with typical palmar and plantar primary hyperhidrosis treated by thoracic video-assisted sympathectomy; the inclusion period was 16 months and the final follow-up time was 623 ± 15,13 days in average. They were assessed in hospital stay (pain, lung expansion technique and residual pneumothorax) and at seventh postoperative day (pain, surgical results and satisfaction)...

OBJETIVO: Descrever os resultados clínicos e o grau de satisfação de pacientes submetidos à simpatectomia torácica ao nível de 4ª e 5ª costelas (R4-R5) para o tratamento da hiper-hidrose axilar. MÉTODOS: Foram incluídos 118 pacientes com diagnóstico de hiper-hidrose axilar e submetidos à simpatectomia torácica ao nível de R4-R5, realizada por um único cirurgião, no Hospital de Clínicas da Universidade Federal do Paraná, Curitiba (PR), entre março de 2003 e dezembro de 2007. Dados relativos à resolução da sudorese axilar, ao grau de satisfação com o resultado da cirurgia e ao efeito compensatório no pós-operatório precoce (7 dias) e tardio (1 ano) foram coletados. RESULTADOS: Dos 118 pacientes do estudo, 99 (83,9 por cento) e 81 (68,6 por cento) apresentaram resolução total dos sintomas no pós-operatório precoce e tardio, respectivamente. Houve efeito compensatório em 49 pacientes (41,5 por cento) no pós-operatório precoce e em 77 (65,2 por cento) no pós-operatório tardio. Desses 77, 55 (71,4 por cento) consideraram esses efeitos como leves. No pós-operatório precoce, 110 pacientes (93,2 por cento) estavam satisfeitos com os resultados da cirurgia, enquanto 104 pacientes (88,1 por cento) mantinham-se satisfeitos no pós-operatório tardio. CONCLUSÕES: A simpatectomia ao nível R4-R5 é eficaz na resolução da hiper-hidrose axilar primária. O grau de satisfação dos pacientes com os resultados em longo prazo é alto. O efeito compensatório leve é o principal efeito colateral relacionada a essa técnica.
OBJECTIVE: To describe the clinical results and the degree of satisfaction of patients submitted to thoracic sympathectomy at the level of the fourth and fifth ribs (R4-R5) for the treatment of axillary hyperhidrosis. METHODS: We included 118 patients diagnosed with axillary hyperhidrosis and having undergone axillary sympathectomy at the R4-R5 level between March of 2003 and December of 2007 at the Paraná Federal University Hospital de Clínicas, located in the city of Curitiba, Brazil. All procedures were carried out by the same surgeon. Data regarding the resolution of axillary hyperhidrosis and the degree of patient satisfaction with the surgical outcome, as well as compensatory hyperhidrosis in the early and late postoperative periods (after 7 days and after 12 months, respectively), were collected. RESULTS: Of the 118 patients evaluated, 99 (83.9 percent) and 81 (68.6 percent) showed complete resolution of the symptoms in the early and late postoperative periods, respectively. Compensatory hyperhidrosis occurred in 49 patients (41.5 percent) in the early postoperative period and in 77 (65.2 percent) in the late postoperative period. Of those 77, 55 (71.4 percent) categorized the compensatory hyperhidrosis as mild. In the early postoperative period, 110 patients (93.2 percent) were satisfied with the surgical results, and 104 (88.1 percent) remained so in the late postoperative period. CONCLUSIONS: Sympathectomy at the R4-R5 level is efficient in the resolution of primary axillary hyperhidrosis. The degree of patient satisfaction with the long-term surgical results is high. Mild compensatory hyperhidrosis is the main side effect associated with this technique.

FUNDAMENTO: O nível da atividade nervosa simpática é um dos mais importantes determinantes prognósticos em pacientes com insuficiência cardíaca. OBJETIVO: O propósito dessa investigação foi realizar um estudo de viabilidade do emprego do bloqueio simpático esquerdo por toracoscopia em pacientes com insuficiência cardíaca (IC) para avaliar a segurança e os efeitos imediatos. MÉTODOS: Quinze pacientes com cardiomiopatia dilatada e fração de ejeção do ventrículo esquerdo (FEVE) < 40 por cento, classe funcional II ou III (NYHA) e frequência cardíaca > 65 bpm, a despeito do uso adequado de beta-bloqueadores ou intolerantes a eles, forma selecionados. Dez pacientes foram submetidos à clipagem do espaço inter-espinhal em nível de T3-T4 e da porção inferior dos gânglios estrelados esquerdos através de videotoracocopia, enquanto outros cinco pacientes foram randomizados para um grupo controle. RESULTADOS: Nenhum dos pacientes operados apresentou qualquer evento cardiovascular adverso relacionado ao procedimento cirúrgico no período perioperatório. Dois pacientes do grupo cirúrgico morreram devido a tromboembolismo pulmonar ou infarto do miocárdio nos 6 meses de seguimento inicial, enquanto três pacientes do grupo controle apresentaram progressão da IC e morreram ou desenvolveram choque cardiogênico no mesmo período. Nos pacientes tratados, houve melhora na qualidade de vida, nível de atividade física e FEVE (de 25 ± 9 por cento para 32 ± 8 por cento, p=0,024) aos 6 meses de seguimento, enquanto esses parâmetros não se alteraram nos pacientes do grupo controle. CONCLUSÃO: O bloqueio simpático esquerdo via toracoscopia é factível e parece ser seguro em pacientes com IC grave. Esse estudo inicial sugere que esse procedimento pode ser uma abordagem alternativa eficaz para o bloqueio simpático no tratamento de cardiomiopatias dilatadas.
BACKGROUND: The level of sympathetic nervous activity is a major determinant of prognosis in patients with heart failure. OBJECTIVE: The purpose of this investigation was to perform a proof-of-principle trial of therapeutic endoscopic left thoracic sympathetic blockade in heart failure patients to assess safety and immediate effects. METHODS: Fifteen patients with dilated cardiomyopathy and left ventricular ejection fraction (LVEF) < 40 percent, New York Heart Association functional class II or III, and heart rate > 65 bpm, despite either adequate betablocker use or intolerant to it, were enrolled. Ten patients underwent left infra-stellate ganglion plus T3-T4 interspinal space clipping through videothoracoscopy, while the other five patients were randomized to a control group. RESULTS: None of the treated patients had any procedure-related adverse cardiovascular events at the perioperative period. Two patients from the surgical group died due to pulmonary thromboembolism or myocardial infarction within 6 months of the initial follow-up, while three patients from the control group had heart failure progression and died or developed cardiogenic shock during the same period. Treated patients presented improvement in quality of life, level of physical activity and LVEF (from 25 ± 9 percent to 32 ± 8 percent, p=0.024) at 6 months of follow-up, whereas these parameters did not change in control patients. CONCLUSION: Endoscopic left thoracic sympathetic blockade is feasible and appears to be safe in severe heart failure patients. This initial study suggests that this procedure might be an effective alternative approach to sympathetic blockade in the treatment of dilated cardiomyopathies.
FUNDAMENTO: El nivel de la actividad nerviosa simpática es uno de los más importantes determinantes pronósticos en pacientes con insuficiencia cardíaca. OBJETIVO: El propósito de esta investigación fue realizar un estudio de viabilidad del empleo del bloqueo simpático izquierdo por toracoscopia en pacientes con insuficiencia cardíaca (IC) para evaluar la seguridad y los efectos inmediatos. MÉTODOS: Quince pacientes con cardiomiopatía dilatada y fracción de eyección del ventrículo izquierdo (FEVI) < 40 por ciento, clase funcional II o III (NYHA) y frecuencia cardíaca > 65 lpm, a despecho del uso adecuado de betabloqueantes o intolerantes a ellos, fueron seleccionados. Diez pacientes fueron sometidos a clipaje del espacio interespinal a nivel de T3-T4 y de la porción inferior de los ganglios estrellados izquierdos a través de videotoracocopia, mientras que otros cinco pacientes fueron randomizados para un grupo control. RESULTADOS: Ninguno de los pacientes operados presentó ningún evento cardiovascular adverso relacionado al procedimiento quirúrgico en el período perioperatorio. Dos pacientes del grupo quirúrgico murieron debido a tromboembolismo pulmonar o infarto de miocardio en los 6 meses de seguimiento inicial, mientras tres pacientes del grupo control presentaron progresión de la IC y murieron o desarrollaron shock cardiogénico en el mismo período. En los pacientes tratados, hubo mejora en la calidad de vida, nivel de actividad física y FEVI (de 25±9 por ciento a 32±8 por ciento, p=0,024) a los 6 meses de seguimiento, mientras que esos parámetros no se alteraron en los pacientes del grupo control. CONCLUSIÓN: El bloqueo simpático izquierdo vía toracoscopia es factible y parece ser seguro en pacientes con IC grave. Este estudio inicial sugiere que este procedimiento puede ser un abordaje alternativo eficaz para el bloqueo simpático en el tratamiento de cardiomiopatías dilatadas.

OBJECTIVE: This prospective study aimed at investigating predictive factors for compensatory sweating after thoracoscopic sympathectomy. METHODS: From 2000 to 2002, 80 patients (53 females and 27 males) underwent thoracoscopic sympathectomy to treat hyperhidrosis. Patient ages ranged from 12 to 56 years, and the mean post-operative follow-up period was 42.51 ± 5.98 months. Patient satisfaction with the results was evaluated through the use of a rating scale. The procedure was performed bilaterally: at the T2 level for facial hyperhidrosis; at the T3-T4 level for axillary hyperhidrosis; and at the T3 level for palmar hyperhidrosis. RESULTS: Post-operatively, 68 patients (85.0 percent) presented compensatory sweating, which was classified as mild in 23 (33.8 percent), moderate in 23 (33.8 percent) and severe in 22 (32.4 percent). Considering the final surgical results, 70 patients (87.5 percent) were satisfied with the outcome of the operation, whereas 10 patients (12.5 percent) were dissatisfied. The level of patient satisfaction varied according to gender, age, body mass index (BMI) and extent of denervation. The compensatory sweating was more severe on the abdomen and back than on the legs. CONCLUSIONS: Although compensatory sweating, which is a common adverse effect of sympathectomy, occurred in the majority of cases, the level of patient satisfaction was high. The best candidates for thoracoscopic sympathectomy are young adult women with a BMI < 24.9 kg/m².
OBJETIVO: Este estudo prospectivo visou investigar fatores preditivos para a hiperidrose compensatória após a simpatectomia toracoscópica. MÉTODOS: De 2000 a 2002, 80 pacientes (53 mulheres e 27 homens), com idade entre 12 e 56 anos, foram submetidos à simpatectomia toracoscópica para o tratamento de hiperidrose e acompanhados em média por 42,51 ± 5,98 meses. A satisfação destes pacientes quanto aos resultados do procedimento foi aferida por meio de uma escala de avaliação. O procedimento foi executado bilateralmente: no nível de T2 para a hiperidrose facial; de T3 e T4 para a hiperidrose axilar; e de T3 para a hiperidrose palmar. RESULTADOS: No período pós-operatório, 68 pacientes (85,0 por cento) apresentaram hiperidrose compensatória, que foi classificada como leve em 23 (33,85 por cento), moderada em 23 (33,8 por cento) e grave em 22 (32,4 por cento). Quanto aos resultados da cirurgia, na avaliação dos pacientes, 70 deles (87,5 por cento) se consideraram satisfeitos, enquanto 10 pacientes (12,5 por cento) disseram estar insatisfeitos. O grau de satisfação do paciente variou de acordo com o sexo, a idade, o índice de massa corpórea (IMC) e a extensão da operação. A hiperidrose compensatória foi mais intensa no abdome e dorso do que nas pernas. CONCLUSÕES: Embora a hiperidrose compensatória seja um efeito adverso frequente após a simpatectomia, o grau de satisfação dos pacientes foi elevado. Os melhores candidatos para simpatectomia toracoscópica são mulheres adultas jovens com IMC < 24,9 kg/m².

OBJECTIVE: To compare two surgical techniques (denervation levels) for sympathectomy using video-assisted thoracoscopy to treat palmar hyperhidrosis in the long-term. METHODS: From May 2003 to June 2006, 60 patients with palmar hyperhidrosis were prospectively randomized for video-assisted thoracoscopic sympathectomy at the T2 or T3 ganglion level. They were followed for a mean of 20 months and were evaluated regarding their degree of improvement of palmar hyperhidrosis, incidence and severity of compensatory hyperhidrosis and its evolution over time, and quality of life. RESULTS: Fifty-nine cases presented resolution of the palmar hyperhidrosis. One case of therapeutic failure occurred in the T3 group. Most of the patients presented an improvement in palmar hyperhidrosis, without any difference between the groups. Twenty months later, all patients in both groups presented some degree of compensatory hyperhidrosis but with less severity in the T3 group (p = 0.007). Compensatory hyperhidrosis developed in most patients during the first month after the operation, with incidence and severity that remained stable over time. An improvement in quality of life was seen starting from the first postoperative evaluation but without any difference between the groups. This improvement was maintained until the end of the follow-up. CONCLUSION: Both techniques were effective for treating palmar hyperhidrosis. The most frequent complication was compensatory hyperhidrosis, which presented stable incidence and severity over the study period. Sympathectomy at the T3 level presented compensatory hyperhidrosis with less severity. Nevertheless, the improvement in quality of life was similar between the groups.

To document the possible complications of video-assisted thoracoscopic sympathectomy procedure and their frequency of occurrence. This retrospective study was conducted at King Hussein Medical Center, Amman, Jordan, between April 2001 and January 2006. Two hundred and seven patients underwent thoracoscopic sympathectomy for the treatment of facial, axillary, and/or palmar hyperhidrosis. Follow up was completed for one year. All possible early and late complications were documented and analyzed. Males constituted 59.4% of the studied patients. Mean age range was 25.2 +/- 4.6 13-34 years. One hundred and fifty-three patients 73.9% had palmar hyperhidrosis as the main indication for sympathectomy, 4 patients 1.9% had axillary hyperhidrosis, and facial sweating or blushing in 7 patients 3.4%. Palmar hyperhidrosis combined with axillary and/or facial sweating were found in 43 patients 20.8%. The most common recorded complication was compensatory hyperhidrosis, which occurred in 142 patients 68.6%. Compensatory sweating remains the most common, and most disabling complication of video-assisted thoracoscopic sympathectomy. Other alternative more selective methods, rather than cutting the main trunk should be studied thoroughly to assess their efficacy in reducing the complication of compensatory sweating

INTRODUCTION: Plantar hyperhidrosis is present in 50 percent of patients with hyperhidrosis. Thoracic sympathectomy is an important tool for the treatment of this condition, which is successful in about 60 percent of patients. For the remaining patients, lumbar sympathectomy is the procedure of choice. As new minimally invasive techniques have been developed, a significant demand for this type of access has led to its adaptation to the lumbar sympathectomy. The objective of this study was to evaluate the effectiveness of endoscopic retroperitoneal lumbar sympathectomy in controlling plantar hyperhidrosis and its effects on compensatory sweat. MATERIALS AND METHODS: Thirty female patients with persistent plantar hyperhidrosis after thoracic sympathectomy were enrolled. They were randomly assigned to laparoscopic retroperitoneal lumbar sympathectomy (Group A) or no surgical intervention (Group B - control) groups. Quality-of-life modifications were assessed by specific questionnaires before and after surgery. In the same manner, direct sweat measurements were also performed pre- and post-intervention by evaluating trans-epidermal water loss. Despite the lack of intervention, the control group was evaluated at similar timepoints. RESULTS: In Group A, no major complications occurred in the peri-operative period. During the immediate post-operative period, three patients (20 percent) experienced prolonged pain (more than ten days). Eight patients suffered from worsened compensatory sweating (53.3 percent). In Group A, after lumbar sympathectomy, the quality of life significantly improved (p<0.05, intra-group comparison) beyond that of the control group (p<0.05, inter-group comparison). Also, lumbar sympathectomy resulted in significantly lower values of foot sweat (pre- vs. post-operative periods, p<0.05; Group A vs. Group B, p<0.05). These patients also developed higher values of sweat measurements on specific points of their dorsal and abdominal...

Gustatory hyperhidrosis is facial sweating usually associated with the eating of hot spicy food or even smelling this food. Current options of treatment include oral anticholinergic drugs, the topical application of anticholinergics or aluminum chloride, and the injection of botulinum toxin. Thirteen patients have been treated to date with 1.5% or 2% topical glycopyrrolate. All patients had gustatory hyperhidrosis, which interfered with their social activities, after transthroacic endoscopic sympathectomy, and which was associated with compensatory focal hyperhidrosis. After applying topical glycopyrrolate, the subjective effect was excellent (no sweating after eating hot spicy food) in 10 patients (77%), and fair (clearly reduced sweating) in 3 patients (23%). All had reported incidents of being very embrasssed whilst eating hot spicy foods. Adverse effects included a mildly dry mouth and a sore throat in 2 patients (2% glycopyrrolate), a light headache in 1 patient (1.5% glycopyrrolate). The topical application of a glycopyrrolate pad appeared to be safe, efficacious, well tolerated, and a convenient method of treatment for moderate to severe symptoms of gustatory hyperhidrosis in post transthoracic endoscopic sympathectomy or sympathicotomy patients, with few side effects.
