Whether this is appropriate for minimally invasive approach is not yet clear. We evalu- ated the feasibility of complete video-assisted thoracoscopic surgery （VATS） thymectomy for the treatment of Ma- saoka stage I and Ⅱ thymoma-associated myasthenia gravis, compared to conventional trans-sternal thymectomy. We summarized 33 patients with Masaoka stage I and II thymoma-associated myasthenia gravis between April 2006 and September 2011. Of these, 15 patients underwent right-sided complete VATS （the VATS group） by us- ing adjuvant pneuomomediastinum, comparing with 18 patients using the trans-sternal approach （the T3b group）. No intraoperative death was found and no VATS case required conversion to median sternotomy. Significant differences between the two groups regarding duration of surgery and volume of intraoperative blood loss （P = 0.001 and P 〈 0.001, respectively） were observed. Postoperative morbidities were 26.7% and 33.3% for the VATS and T3b groups, respectively. All 33 patients were followed up for 12 to 61 months in the study. The cumulative probabilities of reaching complete stable remission and effective rate were 26.7% （4/15） and 93.3% （14/15） in the VATS group, which had a significantly higher complete stable remission and effective rate than those in the T3b group （P = 0.026 and P = 0.000, respectively）. We conclude that VATS thymectomy utilizing adjuvant pneuomo- mediastinum for the treatment of stage I and II thymoma-associated myasthenia gravis is technically feasible but deserves further investigation in a large series with long-term follow-up.展开更多

Methods： From November 2011 to June 2013, 32 consecutive patients with PSP were treated by nonintubated uniportal thoracoscopic bullectomy using epidnral anaesthesia and sedation without endotracheal intubation. An incision 2 cm in length was made at the 6th intercostal space in the median axillary line. The pleural space was entered by blunt dissection for placement of a soft incision protector. Instruments were then inserted through the incision protector to perform thoracoscopic bullectomy. Data were collected within a minimum follow-up period of 10 months. Results： The average time of surgery was 49.0 rain （range, 33-65 rain）. No complications were recorded. The postoperative feeding time was 6 h. The mean postoperative chest tube drainage and hospital stay were 19.3 h and 41.6 h, respectively. The postoperative pain was mild for 30 patients （93.75%） and moderate for two patients （6.25%）. No recurrences ofpneumothorax were observed at follow-up. Conclusions： The initial results indicated that nonintubated uniportal video-assisted thoracoscopic operations are not only technically feasible, but may also be a safe and less invasive alternative for select patients in the management of PSP. This is the first report to include the use of a nonintubated uniportal technique in VATS for such a large number of PSP cases. Further work and development of instruments are needed to define the applications and advantages of this technique.展开更多

Methods： A total of 51 patients with radiologically or mediastinoscopically confirmed stage ⅢA lung cancer underwent VATS radical treatment, during which the standard pulmonary lobectomy and mediastinal lymph node dissection were performed after pre-operative assessment. The operative time, intraoperative blood loss/ complications, postoperative recovery, postoperative complications, and lymph node dissection were recorded and analyzed. This study was regarded as successful if the surgical success rate reached 90% or higher. Results： A total of 51 patients with non-small cell lung cancer （NSCLC） were enrolled in this study from March 2009 to February 2010. The median post-operative follow-up duration was 50.5 months. Of these 51 patients, 41 （80.4%） had N2 lymph node metastases. All patients underwent the thoracoscopic surgeries, among whom 50 （98%） received pulmonary lobectomy and mediastinal lymph node dissection completely under the thoracoscope, 6 had their incisions extended to about 6 cm due to larger tumor sizes, and 1 had his surgery performed using a 12 cm small incision for handling the adhesions between lymph nodes and blood vessels. No patient was converted to conventional open thoracotomy. No perioperative death was noted. One patient received a second surgery on the second post-operative day due to large drainage （〉1,000 mL）, and the postoperative recovery was satisfactory. Up to 45 patients （88.2%） did not suffer from any perioperative complication, and 6 （11.8%） experienced one or more complications. Conclusions： VATS radical treatment is a safe and feasible treatment for stage ⅢA lung cancer.展开更多

Middle lobe torsion occurred after right upper and lower lobectomy in a 74-year-old man. Immediate re-exploratory thoracotomy using the 3-cm uniportal VATS approach was performed. The torsion was corrected, and the lobe was anchored to the anterior chest wall with Prolene stitches. The patient recovered well postoperatively with daily improvements in chest radiographic findings. Follow-up examination was performed using fiberbronchoscopy, which revealed an unobstructed right middle lobe bronchus and sticky yellow sputum. Follow-up chest computed tomography was performed 3 months after the primary surgery and revealed increased expansion of the right middle lobe. We repositioned the right middle lobe successfully by using the 3-cm uniportal VATS approach, but more cases are needed to confirm the feasibility of the approach. Lobectomy remains the primary treatment option for such cases.展开更多

However, popularization of this relatively novel technique has been slow, partly due to concerns about its long-term outcomes. The present study aimed to evaluate the long-term survival outcomes of patients with NSCLC after VATS, and to determine the significant prognostic factors on overall survival. Methods： Consecutive patients diagnosed with NSCLC referred to one institution for VATS were identified from a central database. Patients were treated by either complete-VATS or assisted-VATS, as described in previous studies. A number of baseline patient characteristics, clinicopathologic data and treatment-related factors were analyzed as potential prognostic factors on overall survival. Results： Between January 2000 and December 2007, 1,139 patients with NSCLC who underwent VATS and fulfilled a set of predetermined inclusion criteria were included for analysis. The median age of the entire group was 60 years, with 791 male patients （69%）. The median 5-year overall survival for Stage Ⅰ, Ⅱ, Ⅲ and Ⅳ disease according to the recently updated TNM classification system were 72.2%, 47.5%, 29.8% and 28.6%, respectively. Female gender, TNM stage, pT status, and type of resection were found to be significant prognostic factors on multivariate analysis. Conclusions： VATS offers a viable alternative to conventional open thoracotomy for selected patients with clinically resectableNSCLC展开更多

This study aimed to compare the effects of catheter ablation and video-assisted thoracoscopic surgery ablation on PAF. Methods From March 2008 to March 2012, 138 consecutive patients with PAF were randomly assigned to receive either video-assisted thorecoscopic surgery ablation （thoracoscopy group, n=66） or the traditional catheter ablation （catheter group, n=72）. Results No patient died during the study and all were successfully followed and included in analysis. There were no significant differences in clinical and echocardiographic characteristics between the two groups. All patients were evaluated at 1 week, 1 month, 3 months, 6 months, and 12 months after discharge by physical examination and related laboratory tests. Preoperative left atrium dimensions （LADs） of the recurrent AF were （47±4） mm in the thoracoscopy group and （46±8） mm in the catheter group, whereas the LADs were （40±5） and （39±9） mm, respectively, in non-recurrent PAF. Conclusions The short-term outcome of video-assisted thoracoscopic surgery ablation is safe and effective; and the indications are wider than those for catheter ablation. The larger left atrium diameter is related to the recurrence of atrial fibrillation. Chin Med J 2014;127 （14）： 2567-2570展开更多
