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

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

Before operation and 24 h after operation, the differences in serum levels of pain mediators, oxidative stress indexes and inflammation indexes were compared between the two groups of patients.Results: Before operation, the differences in serum levels of pain mediators, oxidative stress indexes and inflammation indexes were not statistically significant between the two groups of patients. 24 h after operation, serum pain mediators NE, DA and 5-HT levels of observation group were lower than those of control group;oxidative stress indexes MDA and O2- levels were lower than those of control group while SOD and GSH-Px levels were higher than those of control group;inflammation indexes IL-6, IL-8, CRP and TNF-α levels were lower than those of control group.Conclusion: Uniportal video-assisted thoracoscopic surgery for the treatment of lung cancer causes less surgery trauma, and patients' postoperative pain and systemic inflammatory stress response are lighter.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
