Objective To investigate the clinical value of using videoassisted thoracoscopic lobectomy（VATS lobectomy） to treat primary nonsmall cell lung cancer(NSCLC) so that the videoassisted thoracoscopic surgery(VATS) can be better used in clinic. Methods From September 2007 to December 2008, seventysix NSCLC patients were collected. Thirtyseven patients underwent VATS lobectomy(VATS group), 21 male and 16 female with an average age of 60.4 years. Among them 20 underwent videoassisted minithoracotomy lobectomy, and 17 underwent total thoracoscopic lobectomy. Thirtynine patients underwent conventional thoractomy(conventional thoracotomy group), 32 male and 7 female with an average age of 58.7 years. Perioperative clinical and laboratory parameters of the two groups were compared. Results There was no severe complication and perioperative mortality in both groups. There were statistical significances between VATS group and conventional thoracotomy group in incision length (7.6±1.9 cm vs. 28.5±3.6 cm, t=-31.390,P=0.000), postoperative dosage of dolantin(160±125 mg vs.232±101 mg，t=-2.789,P=0.007), postoperative chest tube time(chest tube output＞100ml,4.8±2.5 d vs. 8.1±3.2 d，t=-4.944,P=0.000） and postoperative hospitalization time(12.1±3.0 d vs. 15.7±4.7 d，t=-3.945,P=0.000). There was no statistical significance between two groups in operation time（t=1.732，P=0.087）, intraoperative blood loss（t=-1.645，P=0.105） and the number of lymph node dissection（t=-0.088，P=0.930）. The total hospitalization expenses in VATS group were higher than that in conventional thoracotomy group, but there was no statistical significance（t=1.303，P=0.197）. The serum levels of glucose at 1st day after operation（7.2±1.2 mmol/L vs. 8.4±2.2 mmol/L, t=5.603,P=0.000）and the total count of white blood cell (12.7±3.8×10.9/L vs. 15.1±5.9×10.9/L,t=5.082,P=0.004) in VATS group were significantly lower than that in conventional thoracotomy group. The prealbumin(PA) level in VATS group was significantly higher than that in conventional thoracotomy group（215.0±45.5 mg/L vs.147.3+50.8 mg/L,t=-7.931,P=0.000). Conclusion VATS lobectomy could clean lymph node completely. Its advantages include less postoperative trauma, lower acute phase response, mild pain, rapid recovery, shorter hospitalization time and less economic burden. It could be an operation approach for early NSCLC patients who have been strictly selected.
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.
ObjectiveTo compare effectiveness and safety of video-assisted thoracic surgery (VATS) and thoracotomy in lymph node (LN) dissection for lung cancer. MethodsA comprehensive search of PubMed, Ovid Medline, EMbase, Web of Science, ScienceDirect, the Cochrane Library, Scopus and Google Scholar was performed to identify studies (from January 1990 to July 2015) comparing VATS with thoracotomy in LN dissection. The data were analyzed by RevMan 5.3 software. Quality of literature was evaluated by Newcastle-Ottawa scale or Jadad scale. ResultsFifty-one articles met the inclusion criteria involved 7 127 patients in the VATS group and 9 217 patients in the thoracotomy group. Thirty-eight articles were of good quality and the remaining thirteen were medium. Meta-analysis showed that fewer N1 LN stations in the VATS group (95% CI -0.23 to -0.04, P=0.005), although VATS harvested more left-side LNs (95% CI 0.51 to 3.22, P=0.007). The number of total LNs (95% CI -1.81 to 0.28, P=0.15), total LN stations (95% CI -0.34 to 0.15, P=0.44), N2 LNs (95%CI -1.77 to 0.79, P=0.45), N2 LN stations (95% CI -0.22 to 0.16, P=0.78), N1 LNs (95% CI -0.95 to 0.11, P=0.12), and right-side LNs (95% CI -1.52 to 2.23, P=0.71) harvested in the two groups were not significantly different. ConclusionIn the surgical treatment of lung cancer, VATS can achieve the same efficacy of LN dissection as thoracotomy. This conclusion still needs to be further proved by more high-quality and large-scale RCTs.
Objective To investigate the perioperative differences between video-assisted thoracoscopic surgery (VATS) and thoracotomy after neoadjuvant therapy in patients with non-small cell lung cancer (NSCLC). Methods Clinical data of NSCLC patients who underwent VATS or thoracotomy after neoadjuvant therapy at Shanghai Pulmonary Hospital from June 2020 to May 2022 were retrospectively collected. Perioperative outcomes were compared between the two groups. Results A total of 260 patients were enrolled, 184 (70.8%) patients underwent VATS and 76 (29.2%) patients underwent thoracotomy. After propensity matching, there were 113 (62.4%) patients in the VATS group and 68 (37.6%) patients in the thoracotomy group. VATS had similar lymph node dissection ability and postoperative complication rate with thoracotomy (P>0.05), with the advantage of having shorter operative time (146.00 min vs. 165.00 min, P=0.006), less intraoperative blood loss (50.00 mL vs. 100.00 mL, P<0.001), lower intraoperative blood transfusion rate (0.0% vs. 7.4%, P=0.003), less 3-day postoperative drainage (250.00 mL vs. 350.00 mL, P=0.011; 180.00 mL vs. 250.00 mL, P=0.002; 150.00 mL vs. 235.00 mL, P<0.001), and shorter postoperative drainage time (9.34 d vs. 13.84 d, P<0.001) and postoperative hospitalization time (6.19 d vs. 7.94 d, P=0.006). Conclusion VATS after neoadjuvant therapy for NSCLC is safer than thoracotomy and results in better postoperative recovery.
Objective To evaluate the cardiovascular risk for non-cardiac thoracic surgery （NCTS） in elderly patients with dobutamine stress echocardiography and to decrease surgical risk for NCTS in the geriatrics. Methods Dobutamine stress echocardiography was used for cardiovascular evaluation in 32 NCTS candidates aged over 65 years. Patients with positive echocardiography underwent coronary angiography. Postoperative course and all complications were carefully recorded for the study. Results No serious cardiovascular events occurred during the test except for atrial or ventricular premature contracts in 5 cases. In 2 patients （6.7%,2/30） dobutamine test was positive and coronary artery occlusion was proved by further angiography. Thoracotomy was performed in 28 cases, including 2 cases with dubious result at dobutamine test. Cardiopulmonary complications occurred in 13 patients （46.4%,13/28） after surgery. Supraventricular tachyarrhythmia was the most common complication, occurred in 8 patients （28.6%,8/28）. One of the 2 patients with dubious result at dobutamine test developed definitive angina in the 5th postoperative day. The negative predictive value of dobutamine test was 100%. Conclusion Dobutamine stress echocardiography is a safe and effective method to evaluate major cardiovascular risk of NCTS in the geriatrics. But it is not predictive of tachyarrhythmia after surgery.
Clinical scientists have paid more and more attention to the acute respiratory distress syndrome(ARDS), a severe complication after thoracotomy, for its high mortality rate. Compared with other surgical patients, patients who received thoracotomy often have a worse cardiopulmonary function and are prone to suffering from ARDS. Surgical treatment or injury, massive blood transfusion, respiratory tract infection, improper fluid replacement and ventilation are probable reasons to cause ARDS. Mechanical ventilation is an important treatment for ARDS，but ventilation with lungprotective strategies was proved to be the only therapy which can improve the prognosis of patients with ARDS. At present, thinking highly of and promoting the perioperative management, lessening surgical injury and active prevention are still very important measures to reduce the mortality after thoracotomy. This article is aimed to review the high risk factors of ARDS after thoracotomy as well as its treatment.
ObjectiveTo systematically review the postoperative recovery of lung function in patients with early stage non-small cell lung cancer (NSCLC) after different operation, such as lobectomy versus segmentectomy and video-assisted thoracoscopic surgery (VATS) versus traditional open chest surgery.MethodsClinical studies about effect of different surgical methods on lung function in patients with early NSCLC were searched from PubMed, EMbase, The Cochrane Library, CBM and CNKI databases from inception to October 1st, 2016. Two researchers independently screened literature, extracted data and evaluated the risk of bias of included studies, and then meta-analysis was conducted by RevMan 5.3 and MetaAnalyst software.ResultsA total of 25 studies involving 2 924 patients were included. The results of meta-analysis showed that: compared with lobectomy group, one-second rate difference (ΔFEV1%) (MD=–0.03, 95%CI –0.03 to –0.03, P<0.001) and predictive value of forced vital capacity difference (ΔFVC%) (MD=–0.09, 95%CI –0.11 to –0.06, P<0.001) of preoperative to postoperative in segmentectomy group were higher. However, there was no significant difference between two groups in first second forced expiratory volume difference (ΔFEV1) (MD=0.01, 95%CI –0.10 to 0.11, P=0.92). Compared with thoracotomy group, VATS group had lower ΔFEV1 (MD=–0.19, 95%CI –0.27 to –0.10, P<0.0001), ΔFVC (MD=–0.20, 95%CI –0.37 to –0.03, P=0.02), ΔFEV1% (MD=–0.03, 95%CI –0.06 to –0.01, P<0.001) of preoperative to postoperative (≤3 months), and maximum minute ventilation (ΔMVV) (MD=–5.59, 95%CI –10.38 to –1.52, P=0.008) of preoperative to postoperative (≥6 months). However, there were no statistically significant differences in difference of carbon monoxide diffusion rate (ΔDLCO%) (MD=–0.04, 95%CI –0.09 to 0.02, P=0.16), ΔFEV1% (MD=–0.02, 95%CI –0.06 to 0.02, P=0.32) and ΔFEV1 (MD=1.13, 95%CI –0.92 to 3.18, P=0.28).ConclusionThe protective effect of segmentectomy on postoperative pulmonary function is better than that of lobectomy. VATS has a protective effect on the ventilation function within 3 months and 6 months after surgery. Due to limited quantity and quality of included studies, the above conclusions are needed to be validated by more high quality studies.
