It has obvious advantages in the plasticity of mandibular margin, and it is worthy of clinical application.
ABSTRACT
Objective This study aimed to evaluate the safety and efficacy of video-assisted thoracoscopic bipolar radio-frequency ablation in the treatment of isolated paroxysmal atrial fibrillation.Methods From September 2010 to December 2016,Seventy-two consecutive patients with paroxysmal atrial fibrillation underwent video-assisted thoracoscopic bipolar radio-frequency ablation at Fuwai Hospital.There were 50 males and 22 females with an average age of(56.5 ± 10.5) years and duration of atrial fibrillation with (6.5 ± 4.8) years.45 patients had previous catheter ablation.The patients were followed up at postoperative 3 months,6 months,1 year and annually.Success of ablation was defined as sinus rhythm and no duration of ≥30 s for rapid atrial arrhythmias,including atrial fibrillation,atrial flutter or atrial tachycardia in 24 h Holter examination.Univariate and multivariate logistic regression models were used to analyze the risk factors for atrial fibrillation recurrence.Results One patient converted to sternotomy due to bleeding on operation.All patients were successfully discharged.69 patients completed follow-up,with an average follow-up of(28 ± 18)months(3-60 months).The overall success rate was 73.9％,and the success rate without antiarrhythmic drug was 62.3％.Subgroup analysis showed that the success rate was 80％ when left atrial anterior and posterior diameter(LAD) ≤40 mm,and 57.9％ when LAD ＞ 40 mm (P =0.035).Multivariate logistic regression analysis showed that LAD ＞40 mm was an independent risk factor for postoperative recurrence of atrial fibrillation.Conclusion Video-assisted thoracoscopic bipolar radiofrequency ablation is a safe and effective method for the treatment of paroxysmal atrial fibrillation,especially in patients with LAD≤40 mm.
ABSTRACT
Objective To evaluate the efficacy and outcomes with the use of a saline-coupled bipolar sealer during liver resection.Methods 101 patients underwent liver resection for primary hepatic carcinoma at the People's Hospital Affiliated to Zhengzhou University from August 2015 to December 2016.The patients were divided into two groups according to whether the Aquamantys(R) system was used or not.In group A (n =62) the clamp crushing technique was used for liver parenchymal transection.In group B (n =39) the Aquamantys(R) system was used.The intraoperative and postoperative complication rates were compared.Results The operation time in group B was significantly longer than group A (216.4 min vs.253.5 min,P ＜ 0.05).The intraoperaitve blood loss in group B was significantly less than group A (381.1 ml vs.257.2 ml,P ＜ 0.05),and less blood transfusion was required (211.3 ml vs.90.9 ml,P ＜ 0.05).The volume of abdominal drainage fluid in group B in the first and the 5th day was significantly less than group A (242.6 ml vs.199.2 ml,P＜0.05;84.3 ml vs.70.4 ml,P＜0.05,respectively).The drainage tube in group B was taken off earlier than in group A (8.1 d vs.7.0 d,P ＜ 0.05).The average hospitalization stay after surgery in group B was also significantly shorter (13.4 d vs.11.6 d,P ＜ 0.05).There was no significant difference in the overall postoperative complication rate (P ＞ 0.05) between the 2 groups,and no death was observed.Conclusion The use of a saline-coupled bipolar sealer (Aquamantys(R)) in liver resection for hepatocellular carcinoma was associated with less intraoperative blood loss and was better for the patients' postoperative recovery.
ABSTRACT
@#Objective To evaluate the efficacy and clinical significance of bipolar radiofrequency ablation in the treatment of left ventricular aneurysm with ventricular arrhythmias guided by CARTO mapping system. Methods From September 2009 to December 2015, 56 patients with ventricular aneurysm following myocardial infarction were enrolled. All patients suffered different levels of angina pectoris symptoms evaluated by Holter (the frequencies of ventricular arrhythmias more than 3 000 per day). They were divided into two groups according to random ballot and preoperative communication with patients' family members: a bipolar radiofrequency ablation group (n=28, 20 males, 8 females, mean age of 61.21±1.28 years) receiving off-pump coronary artery bypass grafting (OPCABG), ventricular aneurysm surgery combined with bipolar radiofrequency ablation, and a non-bipolar radiofrequency ablation group (n=28, 22 males, 6 females, mean age of 57.46±1.30 years) receiving OPCABG and single ventricular aneurysm surgery. The grade of cardiac function and ventricular arrhythmia was compared between the two groups during pre-operation, discharge and follow-up. Results All patients were discharged successfully. There was no in-hospital death in both two groups. One patient in the non-radiofrequency group had cerebral infarction. All patients were re-checked with Holter before discharge and the frequency of ventricular arrhythmias significantly decreased compared to that of pre-operation in both groups, and was more significant in bipolar radiofrequency ablation group (1 197.00±248.20 times/24 h vs. 1 961.00±232.90 times/24 h, P<0.05). There was significant difference in duration of mechanical ventilation and ICU stay between the two groups (P<0.05). The left ventricular ejection fraction (LVEF), left ventricular end-diastolic diameter (LVEDD) and left ventricular end-systolic diameter (LVESD) significantly improved (P<0.05) after operation in both groups. Conclusion The clinical efficacy of bipolar radiofrequency ablation in the treatment of ventricular aneurysm with ventricular arrhythmia guided by CARTO mapping is safe and effective, but its long-term outcomes still need further follow-up.
ABSTRACT
BACKGROUND: Multiple therapies involving ablative and nonablative techniques have been developed for the rejuvenation of photodamaged skin. Radiofrequency (RF) is emerging as a gentler, nonablative skin-tightening device that delivers uniform heat to the dermis at a controlled depth. OBJECTIVE: To compare the efficacy of bipolar radiofrequency (Polaris™) and 1,550-nm fractional erbium-glass laser (Mosaic™) for the treatment of photoaging using a randomized, split-face, patient- and evaluator-blind study. METHODS: We evaluated the clinical effects after the treatment of photoaging. Ten Asian women (Fitzpatrick skin type III to IV) underwent 9 weeks of treatment (3 sessions at 3-week intervals) with monotherapy (Polaris™) on one side of the face and combination therapy with non-ablative bipolar radiofrequency (Polaris™) and 1,550-nm fractional erbium-glass laser (Mosaic™) on the other side. RESULTS: Among 10 patients, 4 were male and 6 were female. Subjective and objective assessments showed that the combination therapy was more effective. As the number of the treatment sessions increased, there was an accompanying increase in the satisfaction level and efficacy. CONCLUSION: This study suggests that bipolar radiofrequency combined with 1,550-nm fractional erbium-glass laser could be effective treatment for photoaging.

Aortic pseudoaneurysm after cardiac surgery is a rare entity, but it is potentially fatal due to its clinical course along with higher morbidity and mortality rates. Instead of open surgical repair, percutaneous procedures have been introduced as other options for managing an aortic pseudoaneurysm. In this case report, we describe transesophageal echocardiography guidance for successful percutaneous closure of an aortic pseudoaneurysm located in the left ventricular outflow tract by using a type II Amplatzer vascular plug in a patient in whom open surgical repair was not recommended.

ABSTRACT
RACIONAL: Embora a ressecção seja ainda o procedimento de escolha no tratamento curativo das lesões malignas do fígado, o sangramento permanece como fator de morbidade com grande impacto na cirurgia hepática. Com o intuito de minimizar esta complicação, diversas opções tecnológicas têm sido utilizadas, entre elas mais recentemente a radiofrequência, permitindo que o procedimento seja realizado com incisões menores, sem necessidade de clampeamento vascular, com mínima dissecção hepática, ou sangramento. OBJETIVO: Apresentar os resultados em uma série de pacientes utilizando nova técnica de ressecção do parênquima hepático através de agulhas paralelas de radiofrequência bipolar desenvolvidas pelos próprios autores, verificando o impacto no sangramento trans-operatório dos pacientes submetidos à hepatectomias. MÉTODOS: Sessenta pacientes foram submetidos à ressecção hepática através do uso da radiofrequência bipolar. O sangramento per-operatório foi avaliado através da medição do volume coletado em aspirador e pela diferença de peso nas compressas utilizadas durante o procedimento. Todos os casos foram acompanhados em sua função hepatocitária através de exames laboratoriais durante a primeira semana de pós-operatório. RESULTADOS: As ressecções hepáticas foram realizadas com média de 87 minutos, tamanho médio da incisão abdominal de 14 cm e sangramento médio de 58 mililitros. Nenhum paciente recebeu transfusão de sangue ou derivados. Não foram utilizados cateteres venosos centrais. Todos pacientes obtiveram rápida recuperação anestésica, obtendo alta da sala de recuperação para a enfermaria em menos de 12 horas. A drenagem pós-operatória foi anotada até a retirada do dreno abdominal em todos os pacientes. O tempo de internação hospitalar médio foi de 3,2 dias. Após um pico de elevação das provas de função hepática nos primeiros três dias, todos apresentaram retorno destes exames aos parâmetros pré-operatórios ao final do 1o mês. CONCLUSÃO: É possível,...
BACKGROUND: Although the resection is the chosen procedure in the therapeutic treatment of liver malign lesions, the bleeding represents a factor of morbidity with a great impact in the hepatic surgery. With the means of minimizing this complication, several technological options have been utilized, being radiofrequency more recently among them, allowing the procedure to be realized with smaller incisions, without the need of vascular clamping, with minimum hepatic dissection, or bleeding. AIM: To present the results of the use of a new technique of hepatic parenchyma resection through parallel needles of bipolar radiofrequency developed by the authors themselves, verifying the impact in the trans-operation bleeding of patients subjected to hepatectomies. METHODS: Sixty patients were submitted to hepatic resection through the use of bipolar radiofrequency. The pre-operation bleeding was evaluated through the medication of the collected volume in the vacuum and by the weight difference in the compresses utilized during the procedure. All cases were monitored in their hepatocitary function through laboratory tests during the first week of the post-operation. RESULTS: The hepatic resections were realized with the mean of 87 minutes, mean incision size of 14 cm and mean bleeding of 58 ml. None of the patients received blood transfusion or derivatives. Central venous catheters were not utilized. All patients obtained fast anesthetic recuperation, leaving the recuperation room to the ward in less than 12 hours. The post-operation drainage was noted down until the drain removal occurring in all patients. The mean hospitalization time was of 3,2 days. After the elevation peak of the hepatic function tests in the first three days, all patients presented regression of them in a one month. CONCLUSION: It is possible, feasible and valid to use radiofrequency needle to perform hepatectomy, even larger ones, reducing bleeding.

ABSTRACT
Primary hyperhidrosis, a disorder of unknown etiology, is characterized by excessive uncontrollable sweating, most often of the palm surface of the hands, armpits, groin and feet. To decrease the symptoms of hyperhidrosis, drug therapy, iontophoresis, excision of axillary sweat glands and thoracoscopic sympathectomy have been attempted. A lumbar sympathectomy is one of the available choices for the treatment hyperhidrosis of the lower extremities. A 28-year old female patient presented with excessive sweating of her hands and feet. For the treatment of her foot hyperhidrosis, a bipolar radiofrequency ablation system was used to ablate the lumbar sympathetic ganglion, with a successful result. This modality will receive greater attention as an available alternative to lumbar sympathetic neurolysis.
