The experience gained through VATS techniques, enhancement of the surgical instruments ,improvement of high definition cameras and avoidance of intubated general anesthesia have been the greatest advances to minimize the trauma to the patient. Uniportal VATS for major resections has become a revolution in the treatment of lung pathologies since initially described 4 years ago. The huge number of surgical videos posted on specialized websites, live surgery events and experimental courses has contributed to the rapid learning of uniportal major thoracoscopic surgery during the last years. The future of the thoracic surgery is based on evolution of surgical procedures and anesthetic techniques to try to reduce the trauma to the patient. Further development of new technologies probably will focus on sealing devices for all vessels and fissure, refined staplers and instruments, improvements in 3D systems or wireless cameras, and robotic surgery. As thoracoscopic techniques continue to evolve exponentially, we can see the emergence of new approaches in the anesthetical and the perioperative management of these patients. Advances in anesthesia include lobectomies performed without the employment of general anesthesia, through maintaining spontaneous ventilation, and with minimally sedated patients. Uniportal VATS resections under spontaneous ventilation probably represent the least invasive approach to operate lung cancer.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

Isolated mitochondria were treated with either ruthenium red, an inhibitor of the uniporter, spermine, an activator of the uniporter, or in combination with cyclosporin A, an inhibitor of the mitochondrial permeability transition pore. Results showed that ruthenium red inhibited CaCl2-induced mitochondrial permeability transition pore opening, spermine enhanced opening, and cyclosporin A attenuated the effects of spermine. Results demonstrated that the mitochondrial calcium uniporter plays a role in regulating the mitochondrial permeability transition pore in mitochondria isolated from the rat brain cortex.展开更多

Left middle cerebral artery occlusion （MCAO） was induced in rats using the suture method. Following 24 hours of ischemic reperfusion, neurological function scores of rats with MCAO, and rats pretreated with ruthenium red and spermine were significantly lower, however, water content of brain tissue, aquaporin 4 expression and immunoglobulin G （IgG） exudation were significantly higher than those of sham-operated rats. Compared with MCAO rats and spermine-treated rats, neurological function scores were considerably higher, and brain tissue water content, aquaporin 4 expression and IgG exudation decreased in ruthenium red-treated rats. These findings suggest that preventive application of the mitochondrial calcium uniporter inhibitor ruthenium red can significantly decrease aquaporin 4 and IgG expression, influence the permeability of the blood brain barrier, and thereby decrease the extent of cerebral edema.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

The aim of this study was to compare the outcomes of using a single port and two ports to perform video-assisted thoracoscopic sympathectomy for palmar hyperhidrosis. Methods Between April 2006 and February 2008, 20 cases underwent video-assisted thoracoscopic sympathectomy through one port （uniportal group） and 25 cases through two ports （biportal group）. The variables including the operating time, hospital stay, pain scores, postoperative complications, incidence of symptom recurrence and patient satisfaction were compared. The mean postoperative follow-up period was 11.5 months （range, 3-25 months）. Results The hands of all patients were warm and dry after operation. No conversion to open surgery was necessary, and no operative mortality was recorded in either group. The mean inpatient pain scores were significantly higher in the biportal group （1.2±0.6） than that in the uniportal group （0.8±0.5, P=0.025）. For the first three weeks after operation, four out of 20 （20%） patients in the uniportal group constantly suffered from mild or moderate residual pain while eight out of 25 （32%） cases in the biportal group （P=0.366）. Among them, two cases in the uniportal group and five cases in the biportal group need to take analgesics. Our mean operative time （bilateral sympathectomy） in the uniportal group （（39.5±10.0） minutes） was shorter than that in biportal group （（49.7±10.6） minutes, P=0.02）. There were no significant differences between two groups in terms of the mean hospital stay, compensatory sweating, and patient satisfaction. Two patients in the biportal group and three in the uniportal group experienced a unilateral pneumothorax. None of them required chest drainage. No patient experienced Homer＇s syndrome, and no recurrent symptoms were observed in either groups Conclusions Both uniportal and biportal video-assisted thoracoscopic sympathectomy are effective, safe, and minimally invasive for palmar hyperhidrosis. Comparing with the biportal approach, the uniportal approach causes less postoperative pain and less operative time, and is a more reasonable procedure in treatment of palmar hyperhidrosis.展开更多

The aim of this study was to compare the perioperative outcomes of uniportal and triportal thoracoscopic Iobectomy and sublobectomy for early-stage NSCLC. Methods： A total of 405 patients with lung lesions underwent thoracoscopic lobectomy or sublobectomy through a uniportal or triportal procedure in approximately 7-month period （From November 2014 to May 2015）. A propensity-matched analysis, incorporating preoperative variables, was used to compare the short-term outcomes of patients who received uniportal or triportal thoracoscopic lobectomy and sublobectomy. Results： Fifty-eight patients underwent uniportal and 347 patients underwent triportal pulmonary resection. The conversion rate for uniportal and triportal procedure was 3.4% （2/58） and 2.3% （8/347）, respectively. The complication rate for uniportal and triportal procedure was 10.3% and 9.5%, respectively. There was no perioperative death in either group. Most patients had early-stage NSCLC in both groups （uniportal： 45/47, 96%; triportal： 313/343, 91%）. Propensity score-matching analysis demonstrated no significant differences in operation time, intraoperative blood loss, numbers of dissected lymph nodes, number of stations of lymph node dissected, duration of chest tube, and complication rate between uniportal and triportal group for early-stage NSCLC. However, the duration of postoperative hospitalization was longer in the uniportal group （6.83 ± 4.17 vs. 5.42 ± 1.86 d, P = 0.036） compared with the triportal group. Conclusions： Uniportal thoracoscopic lobectomy and sublobectomy is safe and feasible, with comparable short-term outcomes with triportal thoracoscopic pulmonary resection. Uniportal lobectomy and sublobectomy lead to similar cure rate as triportal Iobectomy and sublobectomy for early NSCLC.展开更多

文摘The present study investigated the effects of the mitochondrial calcium uniporter inhibitor ruthenium red and the agonist spermine on cerebral edema in rats with cerebral ischemia reperfusion injury. Left middle cerebral artery occlusion （MCAO） was induced in rats using the suture method. Following 24 hours of ischemic reperfusion, neurological function scores of rats with MCAO, and rats pretreated with ruthenium red and spermine were significantly lower, however, water content of brain tissue, aquaporin 4 expression and immunoglobulin G （IgG） exudation were significantly higher than those of sham-operated rats. Compared with MCAO rats and spermine-treated rats, neurological function scores were considerably higher, and brain tissue water content, aquaporin 4 expression and IgG exudation decreased in ruthenium red-treated rats. These findings suggest that preventive application of the mitochondrial calcium uniporter inhibitor ruthenium red can significantly decrease aquaporin 4 and IgG expression, influence the permeability of the blood brain barrier, and thereby decrease the extent of cerebral edema.
文摘We aimed to describe a method for repositioning of right middle lobar torsion by using a 3-cm uniportal video-assisted thoracoscopic surgery(VATS) approach. 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.

The variables including the operating time, hospital stay, pain scores, postoperative complications, incidence of symptom recurrence and patient satisfaction were compared. The mean postoperative follow-up period was 11.5 months （range, 3-25 months）. Results The hands of all patients were warm and dry after operation. No conversion to open surgery was necessary, and no operative mortality was recorded in either group. The mean inpatient pain scores were significantly higher in the biportal group （1.2±0.6） than that in the uniportal group （0.8±0.5, P=0.025）.

Our mean operative time （bilateral sympathectomy） in the uniportal group （（39.5±10.0） minutes） was shorter than that in biportal group （（49.7±10.6） minutes, P=0.02）. There were no significant differences between two groups in terms of the mean hospital stay, compensatory sweating, and patient satisfaction. Two patients in the biportal group and three in the uniportal group experienced a unilateral pneumothorax. None of them required chest drainage. No patient experienced Homer＇s syndrome, and no recurrent symptoms were observed in either groups Conclusions Both uniportal and biportal video-assisted thoracoscopic sympathectomy are effective, safe, and minimally invasive for palmar hyperhidrosis. Comparing with the biportal approach, the uniportal approach causes less postoperative pain and less operative time, and is a more reasonable procedure in treatment of palmar hyperhidrosis.
文摘Background： Both uniportal and triportal thoracoscopic lobectomy and sublobectomy are feasible for early-stage non-small cell lung cancer （NSCLC）. The aim of this study was to compare the perioperative outcomes of uniportal and triportal thoracoscopic Iobectomy and sublobectomy for early-stage NSCLC. Methods： A total of 405 patients with lung lesions underwent thoracoscopic lobectomy or sublobectomy through a uniportal or triportal procedure in approximately 7-month period （From November 2014 to May 2015）. A propensity-matched analysis, incorporating preoperative variables, was used to compare the short-term outcomes of patients who received uniportal or triportal thoracoscopic lobectomy and sublobectomy. Results： Fifty-eight patients underwent uniportal and 347 patients underwent triportal pulmonary resection. The conversion rate for uniportal and triportal procedure was 3.4% （2/58） and 2.3% （8/347）, respectively. The complication rate for uniportal and triportal procedure was 10.3% and 9.5%, respectively. There was no perioperative death in either group. Most patients had early-stage NSCLC in both groups （uniportal： 45/47, 96%; triportal： 313/343, 91%）. Propensity score-matching analysis demonstrated no significant differences in operation time, intraoperative blood loss, numbers of dissected lymph nodes, number of stations of lymph node dissected, duration of chest tube, and complication rate between uniportal and triportal group for early-stage NSCLC. However, the duration of postoperative hospitalization was longer in the uniportal group （6.83 ± 4.17 vs. 5.42 ± 1.86 d, P = 0.036） compared with the triportal group. Conclusions： Uniportal thoracoscopic lobectomy and sublobectomy is safe and feasible, with comparable short-term outcomes with triportal thoracoscopic pulmonary resection. Uniportal lobectomy and sublobectomy lead to similar cure rate as triportal Iobectomy and sublobectomy for early NSCLC.
文摘目的:研究单孔胸腔镜联合肺段切除外科治疗磨玻璃结节的疗效和安全性。方法:回顾性分析2019年01月至2022年12月我科收治的具有手术指征的79例磨玻璃结节患者行单孔胸腔镜解剖性肺段切除作为研究对象,根据手术方式的不同分成两组,48例患者采用联合肺段切除作为观察组,31例患者采用单个肺段切除作为对照组,对比两组手术相关情况和术后并发症。结果:两组患者在清扫淋巴结、拔除上胸管时间、术后首次下床活动时间、住院时间、术后48 h VAS评分、术后并发症方面,差异无统计学意义(P>0.05)。在手术时间、术中出血量、留置下胸管时间、总引流量、总费用方面,观察组差于对照组(P<0.05)。两组术后随访6~42(23.85±10.12)个月,未有复发、远处转移以及死亡病例发生。结论:磨玻璃结节采用单孔胸腔镜联合肺段切除治疗,安全性和疗效性值得肯定。
文摘Lung major resections involving bronchovascular reconstruction pose a surgical challenge due to their technical complexity and frequency.The traditional techniques to perform vascular or bronchial reconstructions through multiportal video-assisted thoracoscopic surgery(VATS)approach can be applied also by uniportal VATS approach.Nevertheless,specific tools have already been developed in order to facilitate these procedures through uniportal VATS approach increasing comfort and workspace through the single port utility.These procedures must be performed just in very highly uniportal VATS trained teams and it is recommended that teams who perform these techniques previously have completed the advanced learning curve for lung major resections through uniportal VATS approach.The aim of this paper is to describe the major key points for performing most frequent bronchovascular reconstructions through uniportal VATS approach in a safe and feasible way.Operative technique is step by step described in order to safely perform most common uniportal VATS left/right side lung major bronchovascular resections and reconstructions.Specific tip and tricks are detailed in order to facilitate vascular control,bronchovascular reconstructions and unexpected bleeding control through uniportal VATS approach.
