ObjectiveTo systematically evaluate the effectiveness and safety of single-incision video-assisted thoracic surgery (VATS) versus conventional three-port VATS for primary spontaneous pneumothorax. MethodsWe searched databases including PubMed, EMbase, The Cochrane Library, CBM, CNKI and WanFang Data from inception to Dec. 2014, to collect randomized controlled trials (RCTs) and cohort studies comparing single-incision VATS and conventional three-port VATS for primary spontaneous pneumothorax. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Then, RevMan 5.3 software was used for meta-analysis. ResultsA total of 8 cohort studies involving 483 patients were finally included. The results of meta-analysis showed that:Compared with conventional three-port VATS, single-incision VATS had shorter operation time (MD=-3.90, 95%CI -7.22 to -0.58, P=0.02), less amount of intraoperative bleeding (MD=-9.34, 95%CI -15.26 to -3.42, P=0.002), shorter chest drainage time (MD=-0.66, 95%CI -1.02 to -0.29, P=0.000 4), lower VAS score of 24h-postoperative pain (MD=-0.90, 95%CI -1.14 to -0.66, P<0.000 01) and lower incidence of postoperative paresthesia (OR=0.15, 95% CI 0.07 to 0.31, P<0.000 01). Meanwhile, there were no statistical differences between both groups in hospital stay (MD=-0.30, 95%CI -0.63 to 0.03, P=0.08) and the recurrence of pneumothorax (OR=0.68, 95%CI 0.25 to 1.83, P=0.53). ConclusionCurrent evidence shows, single-incision VATS is superior to conventional three-port VATS in the treatment of spontaneous pneumothorax. However, due to limited quality and quantity of included studies, more large-scale, high-quality studies are needed to verify the above conclusion.
ObjectiveTo systematically evaluate the effectiveness and safety of single-incision video-assisted thoracic surgery (VATS) versus conventional multiple ports VATS for lung cancer. MethodsWe searched databases including PubMed, The Cochrane Library (Issue 3, 2016), EMbase, CBM, CNKI and WanFang Data from inception to April 2016, to collect randomized controlled trials (RCTs) and cohort studies comparing single-incision VATS and conventional multiple ports VATS for lung cancer. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Then, RevMan 5.3 software was used for meta-analysis. ResultsA total of 9 cohort studies involving 1 318 patients were finally included. The results of meta-analysis showed that: compared with the conventional multiple ports VATS group, the single-incision VATS group had shorter chest drainage time (MD=-0.70, 95%CI -1.38 to -0.02, P=0.04), shorter hospital stay (MD=-0.52, 95%CI -0.91 to -0.14, P=0.007), less amount of intraoperative bleeding (MD=-18.49, 95%CI -33.61 to -3.37, P=0.02), lower VAS score at 1 and 3 days after surgery (MD=-0.32, 95%CI -0.51 to -0.14, P=0.000 7; MD=-0.48, 95%CI -0.58 to -0.38, P < 0.000 01). Meanwhile, there were no statistical differences between both groups in operation time (MD=-3.40, 95%CI -13.65 to 6.85, P=0.52), the postoperative complications (OR=0.91, 95%CI 0.65 to 1.27, P=0.56), the number of lymph node dissection (MD=-0.79, 95%CI -2.35 to 0.77, P=0.32), the total cost (MD=0.47, 95%CI -0.39 to 1.32, P=0.28), the intraoperative conversion rate (OR=0.92, 95%CI 0.44 to 1.93, P=0.82) and VAS score at 7 days after surgery (MD=-1.18, 95%CI -2.42 to 0.07, P=0.06). ConclusionCurrent evidence shows, single-incision VATS is superior in the surgical trauma to conventional multiple ports VATS in the treatment of lung cancer, However, due to the limited quality and quantity of included studies, more large-scale, high-quality studies are needed to verify the above conclusion.
Objective To investigate the efficacy, early and late outcomes of video-assisted thoracic surgery (VATS) for cN0-pN2 lung cancer patients compared to open lobectomy. Methods We retrospectively reviewed 262 out of 1 754 patients’ clinical records with cN0-pN2 lung cancer who underwent VATS or open lobectomy in our center between January 2009 and December 2014. There were 107 patients in a VATS group with 50 males and 57 females at the age of 61.5±10.7 years, and 155 patients in an open lobectomy group consisting of 104 males and 51 females at the age of 59.0±8.7 years. Results There was no statistical difference in patients’ age, pulmonary function, and underlying diseases between two groups. Operation time was shorter in the open lobectomy group than that in the VATS group (P=0.044). Postoperative in-hospital time was shorter in the VATS surgery group than that in the open lobectomy group (P=0.008). There was an obvious difference in tumor’s maximum diameter (P<0.05). As for mediatinal lymph node, there was no statistical difference in station dissected and positive rate. One year overall survival rate was 91.6% in the VATS group and 81.9% in the open group. Three-year overall survival rate was 58.3% in the VATS group and 47.3% in the open lobectomy group (P<0.05). Conclusion VATS can achieve both the thoroughness and feasibility as the same as open surgery and with better early outcomes. The overall survival rate may have more to do with tumor’s maximum diameter, not the operation method. Still, it needs prospective studies to demonstrate this relationship.
Objective To compare the subaxillary small incision thoracotomy (SSIT) with video-assisted thoracic surgery (VATS) for patients with lung cancer. Methods Retrospective analysis of 142 patients with lung cancer in Department of Thoracic Surgery, The First People's Hospital of Neijiang from January 2014 to April 2016 was conducted. There were 86 males and 56 females, aged 40-77 years. Patients were divided into a VATS group (n=72) and a SSIT group (n=70). The following postoperative data were evaluated: operation time, number of dissected lymph nodes, intraoperative bleeding, postoperative chest drainage volume, drainage duration, postoperative ambulation time, average hospital stay, postoperative complications, hospitalization cost, early postoperative incision pain (visual analogue scale, VAS) and other indicators. Results There were no statistically significant differences between the two groups in the operation time (120.8±20.4 minvs. 126.2±21.6 min,P=0.124), the dissected lymph node (11.1±2.0vs. 11.4±1.9,P=0.333) and the postoperative complications rate (13.9% vs. 15.7%, P=0.759). Laparoscopic intraoperative bleeding and postoperative drainage volume were significantly less in the VATS group than those in the SSIT group (123.2±26.9 mlvs. 156.4±24.0 ml,P<0.001; 227.0±75.5 mlvs. 334.3±89.1 ml,P<0.001). Postoperative drainage duration, postoperative ambulation time and hospital stay were shorter in the VATS group than those in the SSIT group (2.5±0.5 dvs. 3.1±0.6 d, 1.5±0.5 dvs. 2.2±0.6 d, 6.5±0.5 dvs. 7.4±0.6 d, allP<0.001). The average hospitalization cost of the VATS group was significantly higher than that of the SSIT group (42 338.9±8 855.7 yuanvs. 32 043.7±7 178.1 yuan,P<0.001). There was no significant difference in the operation cost and anesthesia cost between the two groups (P>0.05). The early postoperative pain of laparoscopic group was less, but the difference was not statistically significant (P>0.05). Conclusion The hospitalization cost of the SSIT is lower than that of thoracic surgery, which may be beneficial to the appilication in primary hospitals.
Objective To evaluate the effectiveness and safety of single-incision video-assisted thoracic surgery versus conventional multiple ports video-assisted thoracic surgery in the treatment of lung cancer as well as providing reference for clinical decision-making. Methods We searched the Cochrane Library, PubMed, EMbase, CBM, CNKI, VIP, Wanfang ect until March 2017 to collect randomized controlled trials (RCTs), cohort studies, and case-control studies comparing single-incision with conventional multiple ports video-assisted thoracic surgery for lung cancer.Two reviewers independently screened and selected literatures according to inclusion and exclusion criteria. Then data extraction and quality assessment of included studies were conducted. RevMan 5.3 software was used for meta-analysis. Results Twenty-six cohort studies (3 053 patients) were included. The quality of the included studies was high with score more than five.Meta-analysis showed that single-incision video-assisted thoracic surgery had shorter thoracic drainage time (MD=–0.71, 95% CI –1.03 to –0.39), shorter hospitalization time (MD=–0.92, 95% CI –1.66 to –0.19), lower pain scores 1 day after surgery (MD=–0.65, 95% CI –0.90 to –0.40), lower pain scores 3 days after surgery (MD=–0.90, 95% CI –1.16 to –0.64), lower pain scores 7 days after surgery (MD=–1.24, 95% CI –1.90 to –0.57), less number of lymph node dissection (MD=–0.72, 95% CI –1.35 to –0.10), less total drainage fluid (MD=–108.60, 95% CI –180.42 to –36.79) and shorter length of surgical incision (MD=–2.74, 95% CI –3.57 to –1.90) than conventional multiple ports video-assisted thoracic surgery. But the differences between the two groups in operation time, intraoperative blood loss, postoperative complications were not statistically significant. Conclusion Single-incision video-assisted thoracic surgery is safer and better in patient's compliance than conventional multiple ports video-assisted thoracic surgery in the treatment of lung cancer. But there is no significant difference in operation time, intraoperative blood loss, or postoperative complications. It still needs large-scale, high-quality studies to demonstrate its effectiveness and safety.
Objective To share the experience of single-stage bilateral pulmonary resections by video-assisted thoracic surgery (VATS) for multiple nodules. Methods Clinical records of patients undergoing one-stage bilateral resections of multiple pulmonary nodules between January 2015 and December 2016 in our institution were retrospectively reviewed and analyzed. There were 9 males and 15 females, aged from 33 to 69 (55.0±8.0) years. Two patients underwent bilateral lobectomy. Lobar-sublobar (L/SL) resection and bilateral sublobar resection (SL-SL) were conducted in 9 patients and 13 patients respectively. Results All operations completed successfully. Operation time was 135–330 (231.4±59.1) min, duration of use of chest drains was 2–17 (5.4±3.1) days. Overall duration of hospitalization after surgery was 5–37 (8.6±6.3) days. There was no perioperative death. Postoperative course was uneventful in 17 (70.8%) patients. The postoperative complications included one patient of incision infection and one patient of pulmonary infection. Persistent air leak for >3 days duration and unilateral pleural drainage for more than 200 ml/d were observed in 3 patients and 2 patients respectively. Conclusion Single-stage bilateral surgery in selected patients with synchronous bilateral multiple nodules is feasible and associated with satisfactory outcomes.
Objective To investigate the optimal procedure and short-term efficacy of uniportal video-assisted thoracic surgery (U-VATS) lobectomy for lung cancer. Methods The clinical data of 61 patients who underwent lobectomy using U-VATS by the same surgeon between April 2016 and February 2017 were retrospectively analyzed. There were 50 patients (40 males and 10 females, aged 61.4±6.6 years) with conventional procedure. And there were 60 patients (45 males and 15 females, aged 59.2±9.7 years) utilizing multiportal thoracoscopic surgery (M-VATS) during this period. Results The baseline characteristics in both groups such as age, gender, body mass index, comorbidity and tumor size were comparable (P>0.05). There was no postoperative mortality or conversion to thoracotomy in the study. The parameters such as operative time, blood loss, harvested lymph nodes, duration of chest tube drainage, and length of postoperative hospital stay were similar in both groups (P>0.05). However, there was a statistical difference in pain score at 12 h after surgery in favor of the U-VATS approach (3.2vs.4.3, P=0.04). Moreover, subgroup analysis indicated that the operation time using single-direction U-VATS was noticeably shorter than that in both conventional U-VATS and M-VATS (76.4 minvs.125.8 minvs.105.6 min, P<0.05). However, further analysis was not performed because of small sample. Conclusion The short-term efficacy of U-VATS lobectomy for lung cancer is noninferior to M-VATS, meanwhile, single-direction U-VATS lobectomy is feasible followed by shortened operative time.
ObjectiveTo analyze the surgical outcome of patients with lung cancer using double micro-portal video-assisted thoracic surgery (VATS) technique.MethodsWe retrospectively analyzed the perioperative data of 200 patients with primary lung cancer who underwent successful two micro-portal VATS lobectomy between September 2016 and June 2018 at our unit. There were 125 males and 75 females, aged 61.01±8.71 years. The length of the main operating hole was about 2.0–2.5 cm, the size of the secondary operating hole and the observation hole was 0.5 cm individually. Thus, the total length of the three incisions was 3.0–3.5 cm.ResultsThe mean operating time was 99.18±21.77 min, blood loss was 170.35±105.12 ml, and the mean number of dissected lymph node was 15.82±3.33. The mean volume and duration of chest tube were 446.90±195.32 ml and 3.67±1.85 days. The postoperative hospital stay was 5.54±2.41 days. Only one patient died of pulmonary embolism after surgery. There were 7 patients who were converted to thoracotomy. Postoperative pulmonary infection after lobectomy was found in 8 patients. Postoperative air leak over 5 days was developed in 7 patients.ConclusionThe double micro-portal VATS procedure is a safe and effective strategy for patients with lung cancer, which is associated with decreased surgical trauma and less postoperative pain. This emerging technology may benefit patients by enhancing comfort during their postoperative hospitalization.
Chest tube is routinely used after thoracoscopic lung cancer surgery for evacuating air and fluids. Development of enhanced recovery after surgery (ERAS) makes the disadvantages of traditional drainage clearly. In this review, we summarized the advantages and disadvantages of small-bore chest tube, the use of digital drainage system, the time of removing the chest tube, the indications of non chest tube, the improvements of drainage tube hole suture and the complications of chest tube placement after thoracoscopic lung cancer surgery.
In recent years, subxiphoid uniportal video-assisted thoracoscopic surgery is one of the most important innovations in the field of mini-invasive thoracic surgery. Because it avoids the injury of intercostal nerve, previous studies have shown that it can significantly reduce the perioperative and long-term incision pain. The operation is technically more difficult, so the selection of patients is more strict compared with the traditional intercostal surgery. Some special surgical techniques are needed during the operation, and special lengthening instruments should be used. We hope that the experience described in this paper will be continuously supplemented and improved with the further development of this technique, and will produce greater reference value.
