ObjectiveTo explore the reliability and safety of continuous monitoring of vital signs in patients using wireless wearable monitoring devices after video-assisted thoracoscopic surgery (VATS) for lung cancer. MethodsThe patients undergoing VATS for lung cancer in West China Hospital, Sichuan University from May to August 2023 were prospectively enrolled. Both wireless wearable and traditional wired devices were used to monitor the vital signs of patients after surgery. Spearman correlation analysis, paired sample t test and ratio Bland-Altman method were used to test the correlation, difference and consistency of monitoring data measured by the two devices. The effective monitoring rate of the wireless wearable device within 12 hours was calculated to test the reliability of its continuous monitoring. ResultsA total of 20 patients were enrolled, including 15 females and 5 males with an average age of 46.20±11.52 years. Data collected by the two monitoring devices were significantly correlated (P<0.001). Respiratory rate and blood oxygen saturation data collected by the two devices showed no statistical difference (P>0.05), while heart rate measured by wireless wearable device was slightly lower (\begin{document}$ \bar{d} $\end{document}=−0.307±1.073, P<0.001), and the blood pressure (\begin{document}$ \bar{d} $\end{document}=1.259±5.354, P<0.001) and body temperature(\begin{document}$ \bar{d} $\end{document}=0.115±0.231, P<0.001) were slightly higher. The mean ratios of heart rate, respiratory rate, blood oxygen saturation, blood pressure and body temperature collected by the two devices were 0.996, 1.004, 1.000, 1.014, and 1.003, respectively. The 95% limits of agreement (LoA) and 95% confidence interval of 95%LoA of each indicator were within the clinically acceptable limit. The effective monitoring rate of each vital signs within 12 hours was above 98%. ConclusionThe wireless wearable device has a high accuracy and reliability for continuous monitoring vital signs of patients after VATS for lung cancer, which provides a security guarantee for subsequent large-scale clinical application and further research.
ObjectiveTo investigate the effectiveness and safety of robotic lobectomy in clinical N0 lung malignant tumor≥3 cm. MethodsWe retrospectively analyzed the clinical data of 182 patients with lung malignant tumor≥3 cm receiving robotic or thoracoscopic lobectomy at Shanghai Chest Hospital in 2019. The patients were divided into a robotic surgery group (RATS group) and a thoracoscopic surgery group (VATS group). There were 39 males and 38 females with an average age of 60.55±8.59 years in the RATS group, and 51 males and 54 females with an average age of 61.58±9.30 years in the VATS group. A propensity score matching analysis was applied to compare the operative data between the two groups. ResultsA total of 57 patients were included in each group after the propensity score matching analysis. Patients in the RATS group had more groups of N1 lymph node dissected (2.53±0.83 groups vs. 2.07±0.88 groups, P=0.005) in comparison with the VATS group. No statistical difference was found in operation time, blood loss, postoperative hospital stay, number of N1 and N2 lymph nodes dissected, groups of N2 lymph node dissected, lymph node upstage rate or postoperative complications. The hospitalization cost of RATS was higher than that of VATS (P＜0.001). ConclusionIn contrast with thoracoscopic lobectomy, robotic lobectomy has similar operative safety, and a thorough N1 lymphadenectomy in patients with clinical N0 lung malignant tumor≥3 cm.
ObjectiveTo explore clinical outcomes of simutaneous video-assisted thoracoscopic surgery (VATS) for bilateral giant bullae (GB). MethodsClinical data of 160 GB patients who received surgical treatment in the First Affiliated Hospital of Xinjiang Medical University from March 2011 to April 2013 were retrospectively analyzed. According to GB location and surgical strategies, all the patients were divided into 3 groups. In group A, there were 108 patients with spontaneous pneumothorax (SP) and unilateral GB who underwent unilateral GB resection with VATS, including 88 male and 20 female patients with their age of 31.36±16.14 years. In group B, there were 40 patients with SP and bilateral GB who underwent unilateral GB resection in the SP side with VATS, including 36 male and 4 female patients with their age of 37.63±18.84 years. In group C, there were 12 patients with SP and bilateral GB who underwent simultaneous bilateral GB resection with VATS, including 9 male and 3 female patients with their age of 32.58±16.06 years. Postoperative morbidity and SP recurrence rates were analyzed. ResultsAll the operations were successfully performed, and patients were followed up for 20 months after discharge. In group A, postoperative complications included acute pulmonary edema in 1 patient, pleural adhesion in 11 patients, respiratory failure in 2 patients, and pulmonary air leak in 5 patients. During follow-up, SP recurred in 5 patients including 2 patients with SP recurrence at the same side and 3 patients with SP recurrence at the other side of thorax. In group B, postoperative complications included pleural adhesion in 4 patients, respiratory failure in 1 patient, and pulmonary air leak in 3 patients. During follow-up, SP recurred in 18 patients including 3 patients with SP recurrence at the same side and 15 patients with SP recurrence at the other side of thorax. In group C, postoperative complications included pleural adhesion in 2 patients and pulmonary air leak in 1 patient. During follow-up, SP recurred in 1 patient at the same side of thorax. SP recurrence rates of group A and C were significantly lower than that of group B (P=0.000 and P=0.031 respectively). ConclusionSimultaneous VATS is safe, efficacious and reliable for the treatment of bilateral GB, and can effectively prevent SP recurrence at the other side of thorax.
Abstract： Objective To investigate strategies for prevention，early diagnosis，and prompt treatment for acute pulmonary embolism（PE）after video-assisted thoracoscopic surgery（VATS）lobectomy. Methods From January 2007 to November 2010, 1 115 patients with lung cancer underwent VATS lobectomy in the First Affiliated Hospital of Guangzhou Medical College. Among them, 13 patients had acute PE postoperatively, including 6 male patients and 7 female patients with their mean age of 62.3 years（ranging from 42 to 73 years）.All the patients were diagnosed by spiral CT pulmonary artery angiography（SCTPA）, and received anticoagulation therapy with low molecular weight heparin and warfarin. Results The incidence of acute PE after VATS lobectomy was 1.17%（13/1 115）, and the patients with low PE-related early mortality risk accounted for a large proportion（11/13）. There were 12 patients with right-side PE. All the patients’ signs and symptoms were significantly alleviated after administration of anticoagulation therapy. Nine patients received SCTPA review after treatment which showed that their PE had disappeared or been significantly absorbed. No hematological complications including thoracic hemorrhage or wound errhysis occurred after treatment. All surviving patients were followed up for 1 month to 3 months. During follow-up, these patients were alive without PE recurrence. Conclusion SCTPA is the first-choice examination for the diagnosis of acute PE after VATS lobectomy. Prophylaxis against PE and prompt treatment are necessary depending on individual manifestations. VATS lobectomy should be favored as a minimally invasive surgical treatment for patients with lung cancer, for the low incidence of postoperative PE and low PE-related early mortality risk.
Abstract： Objective To investigate videoassisted thoracoscopic surgery (VATS) and percutaneous catheter occlusion (PCO) in interruption of patent ductus arteriosus (PDA), in order to achieve minimally invasive surgical injuries and better clinical results. Methods From November 1995 to September 2009, 312 cases of PDA were treated in Fujian provincial hospital, among whom 252 patients were interrupted with VATS(VATS group) and 60 patients with PCO technique(PCO group). For the VATS group, there were 78 males and 174 females aged from 7 d to 31 years old (9.16±8.91 years), while there were 17 males and 43 females aged from 4 to 57 years old (25.55±14.10 years) in the PCO group. We used titanium clip to interrupt PDA under videoassisted thoracoscope for patients in the VATS group, and adopted Amplatzer method for patients in the PCO group. The clinical results, complications and hospital cost in the two groups were compared in this study. Results In the VATS group, all the PDA were successfully interrupted with no residual shunt. In the PCO group, 5% (3/60) of the patients had minor residual shunt after the procedure. No mortality occurred in both groups. Time of the procedure and hospital stay in the PCO group were shorter than that in the VATS group (70.20±31.20 min vs. 112.50±16.30 min, t=6.344,P=0.002; and 4.70±2.20 d vs. 6.50±2.80 d, t=3.241, P=0.022, respectively). However, the hospital cost for each patient in the PCO group was much higher than that in the VATS group (23 222.00±4 333.40 yuan RMB vs. 8 904.50±2 634.60 yuan RMB,t=25.360, P=0.000). Conclusion Compared with PCO, VATS in interrupting PDA can achieved not only excellent clinical results, especially in the newborn and baby cases, but also very satisfying cost which is just a little more than one third of the PCO cost.
Treatment of Non-small Cell Lung Cancer by Single-direction Four-hole Complete Video-assisted Thoracoscopic Lobectomy HUANG Jia, ZHAO Xiao-jing, LIN Hao, TAN Qiang, DING Zheng-ping, LUO Qing-quan. (Shanghai Lung Tumor Clinical Medical Center, Department of Thoracic Surgery, Shanghai Chest Hospital, Shanghai 200030, P. R. China) Corresponding author：LUO Qing-quan, Email：luoqingquan@hotmail. com Abstract： Objective To explore the feasibility and safety of single-direction four-hole video-assisted thoracoscopic lobectomy in the treatment of non-small cell lung cancer (NSCLC). Methods Between January 2007 and December 2010, 428 patients with NSCLC were surgically treated by single-direction complete video-assisted thoracoscopic lobectomy in Shanghai Chest Hospital. There were 186 males and 242 females; aged 33 to 78 years. All the patients were diagnosed as primary NSCLC at early clinical stage. Among the 428 patients, 134 patients underwent right upper lobectomy, 48 patients underwent right middle lobectomy, 98 patients underwent right lower lobectomy, 4 patients underwent right middle and lower lobectomy, 72 patients underwent left upper lobectomy, and 72 patients underwent left lower lobectomy. All the 428 patients were divided into two groups according to their surgical approach：a three-hole group (300 patients) and a four-hole group (128 patients).The clinical results of the two groups were analyzed. Results A total of 412 patients underwent complete video-assisted thoracoscopic lobectomy, and 16 patients (3.7%) underwent conversion to open surgery. The average operation time was 132.1 (120-180) min, average length of incision was 3.7 (3-5) cm, and average blood loss was 150.0 (50-800) ml. There was no statistical difference in extubation time, intraoperative blood loss, and postoperative hospital stay between the two groups. But the operation time of the four-hole group is significantly shorter than that of the three-hole group （P＜0.05）. The 16 patients who underwent conversion to open surgery received intraoperative blood transfusion. Five patients died of severe pulmonary infection, pulmonary embolism, and acute cerebral infarction. Fifty two patients had squamous cancer, 340 patients had adenocarcinoma, 20 patients had adenosquamous carcinoma, 8 patients had poorly differentiated carcinoma, 6 patients had big cell lung cancer, and 2 patients had carcinoid. Postoperative persistent lung air leak occurred in 4 patients, thoracic empyema in 2 patients, pulmonary infection in 4 patients, arrhythmia in 26 patients, pulmonary embolism in 2 patients, chylothorax in 2 patients, and acute cerebral infarction in 2 patients. The overall 3-year survival rate was 83.6%（358/428）. Conclusion Single-direction four-hole complete video-assisted thoracoscopic lobectomy is feasible, safe and consistent with the operation standard in the surgical treatment for NSCLC patient. It is also helpful to reduce the operation time and facilitate lymph node dissection.

ObjectiveTo explore the feasibility of early chest tube removal following single-direction uniportal video-assisted thoracoscopic surgery (S-UVATS) anatomical lobectomy. MethodsThe clinical data of consecutive VATS lobectomy by different surgeons in Xuzhou Central Hospital between May 2019 and February 2022 were retrospectively reviewed. Finally, the data of 1 084 patients were selected for analysis, including 538 males and 546 females, with a mean age of 61.0±10.1 years. These patients were divided into a S-UVATS group with 558 patients and a conventional group (C-UVATS) with 526 patients according to the surgical procedures. The perioperative parameters such as operation time, blood loss were recorded. In addition, we assessed the amount of residual pleural effusion and the probability of secondary thoracentesis when taking 300 mL/d and 450 mL/d as the threshold of chest tube removal. ResultsTumor-negative surgical margin was achieved without mortality in this cohort. As compared with the C-UVATS group, patients in the S- UVATS group demonstrated significantly shorter operation time (P<0.001), less blood loss (P=0.002), lower rate of conversion to multiple-port VATS or thoracotomy (P=0.003), but more stations and numbers of dissected lymph nodes as well as less suture staplers (P<0.001). Moreover, patients in the S-UVATS demonstrated shorter chest tube duration, less total volume of thoracic drainage and shorter postoperative hospital stay, with statistical differences (P<0.001). After excluding patients of chylothorax and prolonged air leaks>7 d, subgroup analysis was performed. First, assuming that 300 mL/d was the threshold for chest tube removal, as compared with the C-UVATS group, patients in the S-UVATS group would report less residual pleural effusion and less necessitating second thoracentesis with residual pleural effusion>500 mL (P<0.05). Second, assuming that 450 mL/d was the threshold for chest tube removal, as compared with the C-UVATS group, the S-UVATS group would also report less residual pleural effusion and less necessitating second thoracentesis with residual pleural effusion>500 mL (P<0.05). Further multivariable logistic regression analysis indicated that S-UVATS was significantly negatively related to drainage volume>1 000 mL (P<0.05); whereas combined lobectomy, longer operation time, more blood loss and air leakage were independent risk factors correlated with drainage volume>1 000 mL following UVATS lobectomy (P<0.05). ConclusionThe short-term efficacy of S-UVATS lobectomy is significantly better than that of the conventional group, indicating shorter operation time and less chest drainage. However, early chest tube removal with a high threshold of thoracic drainage volume probably increases the risk of secondary thoracentesis due to residual pleural effusion.
Objective To evaluate the clinical effects of harmonic scalpel application in thoracoscopic surgery for lung cancer, which may guide its reasonable application. Methods We retrospectively analyzed the clinical data of 145 lung cancer patients receiving thoracoscopic surgery from January to March 2017 in our hospital. There were 57 patients with thoracoscopic pulmonary wedge resection, and harmonic scalpel was used in 34 patients (8 males, 26 females at age of 59.68±10.91 years), and was not used in 23 patients (13 males and 10 females at age of 59.13±11.21 years). There were 88 patients receiving thoracoscopic pulmonary lobectomy, among whom harmonic scalpel was used in 80 patients (36 males and 44 females at age of 59.68±10.91 years), and was not used in 8 patients (5 males, 3 females at age of 61.63±5.60 years). We recorded the perioperative outcomes of all patients. Results In the 34 patients undergoing thoracoscopic pulmonary wedge resection by harmonic scalpe, the operation time was 90.09±43.52 min, the blood loss was 21.32±12.75 ml, the number of lymph nodes resected was 5.12±4.26, duration of drainage was 3.15±1.16 d, volume of drainage was 535.00±291.69 ml, the length of postoperative hospital stay was 4.56±1.40 d, and no postoperative complication was observed. In the 80 patients receiving thoracoscopic pulmonary lobectomy by harmonic scalpel, operation time was 131.88±41.82 min, blood loss was 42.79±31.62 ml, the number of lymph nodes resected was 13.54±8.75, duration of thoracic drainage was 4.47±2.30 d, drainage volume was 872.09±585.24 ml, the length of postoperative hospital stay was 5.81±2.26 d, and 20 patients had postoperative complications. No complication occurred in the 8 patients without harmonic scalpel. Conclusion Harmonic scalpel showed satisfactory effectiveness and safety in lung cancer thoracoscopic surgery.
ObjectiveTo systematically evaluate the clinical outcomes of minimally invasive lung segment resection (MILSR) and lobe resection (MILLR) for stageⅠA non-small cell lung cancer (NSCLC) to provide reference for clinical application. MethodsOnline databases including The Cochrane Library, PubMed, EMbase, Web of Science, SinoMed, CNKI, and Wanfang were searched from inception to January 21, 2023 by two researchers independently. The quality of the included literature was evaluated using the Newcastle-Ottawa Scale (NOS). The prognostic indicators included the overall survival (OS), disease-free survival (DFS) and recurrence-free survival (RFS). The meta-analysis was performed using STATA 14.0. ResultsA total of 13 studies with 1 853 patients were enrolled in the final study, with NOS scores ≥7 points. The results of meta-analysis showed that compared with the MILLR group, the blood loss was less [SMD=−0.36, 95%CI (−0.49, −0.23), P<0.001], postoperative drainage tube retention time [SMD=−0.34, 95%CI (−0.62, −0.05), P=0.019] and hospitalization time [SMD=−0.28, 95%CI (−0.40, −0.15), P<0.001] were shorter in the MILSR group. More lymph nodes [SMD=−0.65, 95%CI (−0.78, −0.53), P<0.001] and shorter operation time [SMD=0.20, 95%CI (0.07, 0.33), P=0.003] were found in the MILLR group. There were no statistical differences in the incidence of postoperative complications, postoperative recurrence rate, OS, DFS or RFS between the two groups. ConclusionAlthough the number of lymph nodes removed by MILSR is limited compared with MILLR, it does not affect the prognosis. MILSR has advantages in reducing intraoperative blood loss and shortening postoperative drainage tube retention time and hospital stay. For the surgical treatment of stageⅠA NSCLC, MILSR may be a more appropriate surgical approach.
Objective To compare the surgical trauma between videoassisted thoracoscopic surgery(VATS) and conventional thoracotomy, and to investigate the possible minimally invasive mechanism. Methods Seventyseven patients who had undergone consecutive operations from April 2005 to January 2006 were chosen from cardiothoracic surgery department of Fujian Provincial Hospital. Twentytwo cases had spontaneous pneumothorax diagnosed by chest X-ray examination, twentynine had patent ductus arteriosus diagnosed by color echocardiography, and twentysix had congenital atrial septal defect. According to lesions and operative methods, the patients were divided into two groups: conventional thoracotomy group(CTH group) and videoassisted thoracoscopic surgery group(VATS group). The concentrations of serum C-reactive protein（CRP），interleukin6 (IL-6)，interleukin-8（IL-8） and tumor necrosis factor-α(TNF-α) were selected as indexes to measure surgical trauma. ARRAY360 specific protein and pharmaceutical analysis system were used to determine CRP automaticly at the day before operation and on the 1st, 2nd and 3rd day after operation. Radioimmunoassay was used to measure the concentrations of IL-6，IL-8 and TNF-α. Clinical indexes such as operative time, cardiopulmonary bypass (CPB) time, intraoperative blood lost, postoperative analgesic time and hospitalization time were analyzed and compared. Results Under the condition that patients had the same diseases, there was no statistical significance in preoperative concentrations of serum CRP，IL-6，IL-8 and TNFα between VATS group and CTH group（P=0.067, 0.062, 0.053,0.064）. The concentrations of serum CRP(P=0.045,0.043,0.044), IL-6(P=0.042，0.032，0.039), IL-8(P=0.046，0.045，0.048) and TNF-α(P=0.041，0.043，0.043) on the 1st, 2nd and 3rd day after operation were significantly lower in VATS group than that in CTH group (Plt;0.05). Compared with CTH group, there were less blood lost（P=0.032）, shorter postoperative analgesic time and hospitalization time（P=0.041） in VATS group. There was no statistical significance in CPB time between two groups. However, hospitalization time varied with different diseases. Conclusion Compared with conventional thoracotomy，videoassisted thoracoscopic surgery has less surgical trauma, less intraoperative blood lost, shorter postoperative analgesic time, and can make patients recover rapidly. So it is worth spreading.
