Objective To analyze the perioperative outcomes of uniportal thoracoscopic lobectomy compared with three-port thoracoscopic lobectomy. Methods Data were extracted from the Western China Lung Cancer Database, a prospectively maintained database at the Department of Thoracic Surgery, West China Hospital, Sichuan University. Perioperative outcomes of the patients who underwent uniportal or three-port thoracoscopic lobectomy for lung cancer during January 2014 through April 2021 were analyzed by using propensity score matching. Altogether 5 817 lung cancer patients were enrolled who underwent thoracoscopic lobectomy (uniportal: 530 patients; three-port: 5 287 patients). After matching, 529 patients of uniportal and 1 583 patients of three-port were included. There were 529 patients with 320 males and 209 females at median age of 58 (51, 65) years in the uniportal group and 1 583 patients with 915 males and 668 females at median age of 58 (51, 65) years in the three-port group. Results Uniportal thoracoscopic lobectomy was associated with less intraoperative blood loss (20 mL vs. 30 mL, P<0.001), longer operative time (115 min vs. 105 min, P<0.001) than three-port thoracoscopic lobectomy. No significant difference was found between the two groups regarding the number of lymph node dissected, rate of conversion to thoracotomy, incidence of postoperative complication, postoperative pain score within 3 postoperative days, length of hospital stay, or hospitalization expenses. Conclusion Uniportal video-assisted thoracoscopic lobectomy is safe and effective, and the overall perioperative outcomes are comparable between uniportal and three-port strategies, although the two groups show differences in intraoperative blood loss.
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 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.
In order to optimize the postoperative rehabilitation path of patients undergoing fourth-level day surgery, West China Hospital of Sichuan University has learned from the abroad “recovery hotel” mode and innovatively regarded the primary rehabilitation institution as an extended service carrier for thoracoscopic lung nodule day surgery. This extended rehabilitation mode based on primary rehabilitation institutions is not only beneficial for shortening the hospitalization period and reducing medical costs, but also ensures medical safety through a standardized postoperative monitoring system, providing innovative solutions for the full process management of day surgeries. This article will introduce the specific implementation methods and preliminary practical results of the extended rehabilitation mode mentioned above.
ObjectiveTo compare the surgical efficacy of Da-Vinci robot-assisted thoracic surgery (RATS) and video-assisted thoracic surgery (VATS) for non-small cell lung cancer (NSCLC). MethodsOnline databases including PubMed, EMbase, Web of Science, The Cochrane Library, CNKI, Wanfang, VIP and CBM from inception to 18 February, 2022 were searched by two researchers independently. The references of related studies were also searched to re-enroll the potential studies. The quality of the studies was evaluated with Newcastle-Ottawa Scale (NOS). The meta-analysis was performed by RevMan 5.3. Results A total of 43 studies including 33 089 patients were enrolled in the final study. The NOS scores of the included studies were ≥6 points. The results of meta-analysis showed that the operation time was longer [MD=8.50, 95%CI (1.59, 15.41), P=0.020], the blood loss was less [MD=−46.58, 95%CI (−62.86, −30.29), P＜0.001], the dissected lymph nodes stations were more [MD=0.67, 95%CI (0.40, 0.93), P＜0.001], the dissected lymph nodes were more [MD=2.39, 95%CI (1.43, 3.36), P＜0.001], the conversion rate was lower [OR=0.52, 95%CI (0.46, 0.59), P＜0.001], the time of chest tube drainage was shorter [MD=−0.35, 95%CI (−0.58, −0.11), P=0.004], the length of hospital stay was shorter [MD=−0.32, 95%CI (−0.45, −0.19), P＜0.001], and the recurrence rate was lower [OR=0.51, 95%CI (0.36, 0.72), P＜0.001] in the RATS group than those in the VATS group. The rate of overall postoperative complications [OR=0.95, 95%CI (0.89, 1.01), P=0.110] and postoperative mortality rate [OR=0.85, 95%CI (0.62, 1.16), P=0.300] were not significantly different between the two groups. ConclusionCompared with VATS, although RATS prolongs the operation time, it does not increase the incidence of postoperative complications and mortality rates. Moreover, RATS can dissect more lymph nodes, effectively control intraoperative bleeding, shorten the duration of chest drainage tube indwelling and shorten the postoperative hospital stay to a certain extent.
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 compare the perioperative results between uniportal and three-portal thoracoscopic lobectomy for non-small cell lung cancer (NSCLC). Methods Electronic databases including PubMed, Web of Science, EMbase, CNKI, Wanfang were systematically searched from the establishment of each database until April 2022. Literature screening, data extraction and bias risk assessment were independently conducted by two researchers. All combined results were performed by RevMan 5.3 and Stata 16.0. The quality of the literature and the risk of bias were evaluated using the Cochrane Bias Risk Assessment Tool. Results Eighteen eligible randomized controlled trials (1 597 patients) were identified eventually, including 800 patients undergoing uniportal thoracoscopic lobectomy and 797 patients undergoing three-portal thoracoscopic lobectomy. Meta-analysis results showed that compared to the three-portal approach, uniportal lobectomy took longer operation time (WMD=7.63, 95%CI 2.36 to 12.91, P=0.005) with less intraoperative blood loss (WMD=–28.81, 95%CI –42.54 to –15.08, P<0.001). Furthermore, patients undergoing uniportal lobectomy achieved lower visual analogue score within 24 hours after the operation (WMD=–1.60, 95%CI –2.26 to –0.94, P<0.001), less volume of drainage after the operation (WMD=–25.30, 95%CI –46.22 to –4.37, P=0.020), as well as shorter drainage duration (WMD=–0.36, 95%CI –0.72 to –0.01, P=0.040). Besides, patients undergoing uniportal lobectomy were also observed with shorter length of hospital stay (WMD=–2.28, 95%CI –2.68 to –1.88, P<0.001) and lower incidence of postoperative complications (RR=0.49, 95%CI 0.38 to 0.63, P<0.001). However, the number of lymph nodes harvested during the operation (WMD=–0.01, 95%CI –0.24 to 0.21, P=0.930) was similar between the two groups. Conclusion Both uniportal and three-portal thoracoscopic lobectomy for NSCLC are safe and feasible. The uniportal approach is superior in reducing short-term postoperative pain, postoperative complications and shortening the length of hospital stay.
ObjectiveTo analyze the pathological manifestations and imaging characteristics of bronchiolar adenoma (BA).MethodsThe clinical data of 11 patients with BA who received surgeries in our hospital from January 2019 to September 2020 were retrospectively analyzed, including 5 males and 6 females aged 40-73 (62.40±10.50) years. The intraoperative rapid freezing pathological diagnosis, postoperative pathological classification, cell growth pattern, nuclear proliferation index Ki-67 and other immunohistochemical staining combined with preoperative chest CT imaging characteristics were analyzed.ResultsThe average preoperative observation time was 381.10±278.28 d. The maximum diameter of imaging lesions was 5-27 (10.27±6.34) mm. Eight (72.7%) patients presented with irregular morphology of heterogeneous ground-glass lesions, and 3 (27.3%) patients presented with pure ground-glass lesions. There were 10 (90.9%) patients with vascular signs, 8 (72.7%) patients with vacuolar signs, 1 (9.1%) patient with bronchus sign, 3 (27.3%) patients with pleural traction and 9 (81.8%) patients with burr/lobular sign. The surgical methods included sub-lobectomy in 10 patients and lobectomy in 1 patient. Five (45.5%) patients were reported BA by intraoperative frozen pathology. The postoperative pathological classification included 8 patients with distal-type and 3 patients with proximal-type, and the maximum diameter of the lesions was 4-20 (8.18±5.06) mm. Eight (72.7%) patients showed characteristic bilayer cell structure under microscope, and 10 (90.9%) patients showed thyroid transcription factor 1 expression in pathological tissues. The expression of NapsinA in intracavity cells was found in 9 (81.8%) patients. The Ki-67 index of the lesion tissue was 1%-5% (3.22%±1.72%).ConclusionThe pathological features and imaging findings of BA confirm the premise that BA is a neoplastic lesion. However, to identify BA as a benign or inert tumor needs more clinical data and evidence of molecular pathological studies.
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.
ObjectiveTo evaluate the learning curve of CT-guided medical glue localization for pulmonary nodule before video-assisted thoracic surgery (VATS). MethodsThe clinical data of the patients with pulmonary nodules who underwent CT-guided medical glue localization before VATS in our hospital from July 2018 to March 2021 were retrospectively analyzed. The patients were divided into 3 groups: a group A (from July 2018 to August 2019), a group B (from September 2019 to June 2020) and a group C (from July 2020 to March 2021). The localization time, morbidity, complete resection rate and other indexes were compared among the three groups. ResultsA total of 77 patients were enrolled, including 24 males and 53 females aged 57.4±10.1 years. There were 25 patients in the group A, 21 patients in the group B, and 31 patients in the group C. 77 pulmonary nodules were localized. There was no significant difference among the groups in the basic data (P＞0.05). The localization time in the group C was 10.6±2.0 min, which was statistically shorter than that in the group A (15.4±4.4 min) and group B (12.9±4.3 min) (P＜0.01). The incidence of complications in the group C was lower than that in the group A and group B (25.8% vs. 52.0% vs. 47.6%, P=0.04). The success rate of localization of the three groups was not statistically different (P=0.12). ConclusionThere is a learning curve in CT-guided medical glue localization for single pulmonary nodule before VATS. After the first 46 cases, the operation time can be shortened, and the incidence of complications can be decreased.
