ObjectiveTo evaluate the survival results of surgical resection (SR) and CT-guided percutaneous ablation (PA) for stageⅠnon-small cell lung cancer (NSCLC).MethodsThe PubMed, Web of Science, EMbase, The Cochrane Library, CNKI, VIP, Wanfang databases from inception to June 2021 were searched to collect comparative studies on the survival results between SR and CT-guided PA treatment for stageⅠNSCLC. RevMan 5.3 software was used for statistical analysis of data.ResultsA total of 3 114 patients were included in 11 studies. The results of meta-analysis showed that compared with the PA group, the SR group had a higher 2-year postoperative overall survival (OS) rate (OR=1.44, 95%CI 1.00-2.06, P=0.05), 3-year postoperative OS rate (OR=2.37, 95%CI 1.47-3.81, P<0.001), 5-year OS rate (OR=1.64, 95%CI 1.19-2.28, P<0.01), 5-year progression-free survival rate after operation (OR=2.43, 95%CI 1.54-3.82, P<0.001) and lower local recurrence rate (OR=0.26, 95%CI 0.13-0.54, P<0.001). There were no statistical differences between the two groups in terms of 1-year postoperative OS rate, 1-year, 2-year, and 3-year tumor-related survival rates, 1-year, 2-year tumor-free survival rates, or distant postoperative recurrence rate (P>0.05).ConclusionFor patients with stageⅠNSCLC with optimal basic conditions, surgery is a more appropriate treatment. For patients who cannot withstand surgical injuries or refuse surgery, CT-guided PA is also a potential alternative treatment. However, this conclusion needs to be verified by prospective controlled trials with larger sample sizes and a more rigorous design.
ObjectiveTo evaluate the relationship between four classic inflammatory biomarkers, including C-reactive protein (CRP), white blood cell (WBC), IL (interleukin family), tumor necrosis factor-α (TNF-α), and postoperative atrial fibrillation (POAF) after coronary artery bypass grafting (CABG) and valve replacement (VR) surgeries.MethodsWe searched PubMed, EMBase, the Cochrane Library, Ovid, Chinese Journal Full-text Database, Chinese Biomedical Literature Database, VIP database and WanFang database from the inception to April 2020. Studies on the relationship between POAF and the above four inflammatory biomarkers were analyzed. Two researchers independently reviewed the literature, extracted data and evaluated the quality of the literature. RevMan 5.3 software was used for meta-analysis.ResultsA total of 47 articles were included, covering 10 711 patients. The levels of preoperative CRP (SMD=0.38, 95%CI 0.14-0.62, Z=3.12, P=0.002) and postoperative CRP (SMD=0.40, 95%CI 0.06-0.74, Z=2.33, P=0.02), IL-6 (SMD=1.34, 95%CI 0.98-1.70, Z=7.26, P<0.001) and TNF-α (SMD=?0.33, 95%CI ?0.65-?0.01, Z=2.02, P=0.040) were related to POAF, while preoperative IL-8 (SMD=?0.05, 95%CI ?0.28-0.18, Z=0.42, P=0.68) and TNF-α (SMD=?0.43, 95%CI ?1.22-0.36, Z=1.07, P=0.28), postoperative WBC (WMD=1.16, 95%CI ?0.09-2.42, Z=1.82, P=0.07) and IL-10 (SMD=0.21, 95%CI ?0.35-0.77, Z=0.73, P=0.46) were not related to POAF. The relationships between preoperative WBC and IL-10, postoperative IL-8 and POAF were inclusive, which needed further verification. Furthermore, the relationship between postoperative CRP and POAF were not consistent, as they were not significantly correlated in sub-group analysis.ConclusionThe inflammatory substrate before the surgery and inflammatory reaction induced by the operation is related to the occurrence and maintenance of POAF. Compared with preoperative inflammatory status, postoperative inflammatory factors may have a greater predictive value for POAF. Preoperative CRP, postoperative IL-6 and TNF-α levels are reliable biomarkers of POAF.
ObjectiveTo compare the safety and efficacy of powered anastomosis versus mechanical anastomosis in gastrointestinal surgery. MethodsComputerized searches were conducted in PubMed, EMbase, Web of Science, CNKI, and CBM databases to collect studies comparing the safety and efficacy of powered versus mechanical anastomosis in gastrointestinal surgery. The search period was from the inception of each database to March 2025. Literature was screened according to inclusion and exclusion criteria, data were extracted, and the risk of bias was assessed. The quality of the included studies was evaluated using the Newcastle-Ottawa Scale (NOS). Meta-analysis was performed using the Metan package in Stata/MP 17.0 software. ResultsA total of 15 observational studies (13 retrospective and 2 prospective) involving 21,424 patients were finally included, with 9 823 patients in the experimental group (powered anastomosis) and 11 601 patients in the control group (mechanical anastomosis). The NOS scores of all included studies were ≥5 points. Meta-analysis results showed that, compared to the mechanical anastomosis group, the powered anastomosis group had significantly lower incidence rates of anastomotic leakage [RR=0.60, 95%CI (0.37, 0.96), P=0.031], postoperative complications [RR=0.68, 95%CI (0.53, 0.86), P<0.01], intraoperative bleeding rate [RR=0.29, 95%CI (0.15, 0.56), P<0.01], and 30-day readmission rate [RR=0.62, 95%CI (0.39, 0.97), P<0.05]. No statistically significant differences were found in anastomotic stenosis [RR=0.53, 95%CI (0.18, 1.57), P=0.25], intraoperative blood loss [SMD=?0.03, 95%CI (?0.15, 0.08), P=0.57], operation time [SMD=?0.00, 95%CI (?0.08, 0.07), P=0.90], or postoperative hospital stay [SMD=?0.05, 95%CI (?0.13, 0.02), P=0.15]. ConclusionIn gastrointestinal surgery, powered anastomosis may offer potential advantages over traditional mechanical anastomosis in improving the aforementioned safety and efficacy outcomes.
Objective To systematically evaluate the safety and efficacy of percutaneous closure of atrial septal defect (ASD) guided by echocardiography alone versus fluoroscopy. Methods The databases of PubMed, The Cochrane Library, EMbase, VIP, Wanfang Data and CNKI from January 2000 to October 2021 were searched by computer for relevant research literature. Two reviewers independently screened the literature, extracted the data and evaluated the quality according to the inclusion and exclusion criteria. Meta-analysis was performed using RevMan 5.4 software. Results A total of 19 cohort studies and 1 randomized controlled study were collected, including 2 825 patients. The Newcastle-Ottawa Scale score for cohort studies was≥7 points. Meta-analysis showed that there was no statistical difference in the operative success rate (RR=1.01, 95%CI 1.00 to 1.02, P=0.17), incidence of occluder displacement/shedding (RR=0.77, 95%CI 0.26 to 2.27, P=0.63), incidence of arrhythmia (RR=0.50, 95%CI 0.21 to 1.14, P=0.10), incidence of pericardial effusion (RR=0.98, 95%CI 0.32 to 2.98, P=0.97), operative time (MD=–0.23, 95%CI –7.56 to 7.10, P=0.95) or cost (SMD=–0.39, 95%CI –1.09 to 0.30, P=0.27) between the two groups. The echocardiography group reduced the incidence of total postoperative complications (RR=0.42, 95%CI 0.30 to 0.60, P<0.001) and residual shunt (RR=0.70, 95%CI 0.50 to 0.98, P=0.04), and shortened length of hospital stay (MD=–0.43, 95%CI –0.77 to 0.09, P=0.01). Conclusion Compared with traditional fluoroscopy-guided percutaneous closure of ASD, echocardiography guidance alone is equivalent in terms of operative success rate, major postoperative complications, operative time and total cost, but it reduces the incidence of total postoperative complications and residual shunt, and has a shorter length of hospital stay.
ObjectiveTo systematically evaluate the application effect of CT-guided Hook-wire localization and CT-guided microcoil localization in pulmonary nodules surgery. MethodsThe literatures on the comparison between CT-guided Hook-wire localization and CT-guided microcoil localization for pulmonary nodules were searched in PubMed, EMbase, The Cochrane Library, Web of Science, Wanfang, VIP and CNKI databases from the inception to October 2021. Review Manager (version 5.4) software was used for meta-analysis. The Newcastle-Ottawa Scale (NOS) was used to evaluate the quality of studies.ResultsA total of 10 retrospective cohort studies were included, with 1 117 patients including 473 patients in the CT-guided Hook-wire localization group and 644 patients in the CT-guided microcoil localization group. The quality of the studies was high with NOS scores>6 points. The result of meta-analysis showed that the difference in the localization operation time (MD=0.14, 95%CI ?3.43 to 3.71, P=0.940) between the two groups was not statistically significant. However, the localization success rate of the Hook-wire group was superior to the microcoil group (OR=0.35, 95%CI 0.17 to 0.72, P=0.005). In addition, in comparison with Hook-wire localization, the microcoil localization could reduce the dislocation rate (OR=4.33, 95%CI 2.07 to 9.08, P<0.001), the incidence of pneumothorax (OR=1.62, 95%CI 1.12 to 2.33, P=0.010) and pulmonary hemorrhage (OR=1.64, 95%CI 1.07 to 2.51, P=0.020). ConclusionAlthough Hook-wire localization is slightly better than microcoil localization in the aspect of the success rate of pulmonary nodule localization, microcoil localization has an obvious advantage compared with Hook-wire localization in terms of controlling the incidence of dislocation, pneumothorax and pulmonary hemorrhage. Therefore, from a comprehensive perspective, this study believes that CT-guided microcoil localization is a preoperative localization method worthy of further promotion.
Objective To evaluate the postoperative effects of different thoracoscopic sympathectomy on palmar hyperhidrosis patients. Methods We searched the Wanfang Database, CNKI, Weipu, CBM, PubMed, Cochrane Library (from inception to March 2016) to identify studies about thoracoscopic sympathectomy on palmar hyperhidrosis patients. Quality of the included studies was evaluated. The meta-analysis was performed by RevMan5.3 software. Results A total of 15 studies (9 randomized controlled trials, 3 cohort studies, and 3 retrospective studies) involving 2 542 patients were included. The result of meta-analysis suggested that there was statistical difference in postoperative compensatory hyperhidrosis (OR=4.88, 95% CI 1.88 to 12.68,P=0.001) between T2 sympathectomy and T3 sympathectom. Compared with T2-4 sympathectomy patients, the risk of postoperative compensatory hyperhidrosis in T2-4 sympathectomy group was significantly lower (OR=5.13, 95% CI 2.91 to 9.02,P<0.000 01). Compared with T3 sympathectomy group, the risk of postoperative compensatory hyperhidrosis and hand dry in the T4 sympathectomy group was significantly lower (OR=2.91, 95% CI 2.06 to 4.12,P<0.000 01;OR=14.60, 95% CI 3.06 to 69.63,P=0.000 8), respectively. Conclusion The rate of postoperative compensatory hyperhidrosis or hand dry is lower on T4 sympathectomy patients and supposed to be the best segment for the treatment of palmar hyperhidrosis patients.
Objective To systematically evaluate the effectiveness and safety of pulsed field ablation (PFA) and radiofrequency ablation (RFA) in the treatment of atrial fibrillation. Methods Computer searches were conducted on PubMed, EMbase, The Cochrane Library, The Web of Science, China Biomedical Literature Database, CNKI, Wanfang, and VIP databases, with a search period from the establishment of each database until April 2025. Two researchers conducted literature screening, data extraction, and quality evaluation of the included studies based on predetermined inclusion and exclusion criteria. Standardized electronic forms were used for data extraction, with a focus on the balanced dataset after propensity score matching (PSM). Quality evaluation was conducted using the improved Newcastle Ottawa scale (NOS). Meta analysis was conducted using RevMan 5.4 and Stata 18.0 software, and subgroup analysis was performed based on the study type (whether PSM method was used or not). ResultsFinally, 14 studies were ultimately included, of which 6 studies applied the PSM method, with a total sample size of 3 172 cases (PFA group: 1 582 cases; RFA group: 1 590 cases. NOS score≥5 points. The meta-analysis results showed that the PFA group had a lower recurrence rate of atrial fibrillation [OR=0.75, 95%CI (0.63, 0.90), P=0.002], surgical complications [OR=0.63, 95%CI (0.41, 0.98), P=0.04], and surgical time [WMD=–37.32, 95%CI (–45.85, –28.78), P<0.001] compared to the RFA group, and the differences were statistically significant. In addition, compared to the PFA group, the RFA group had a shorter X-ray exposure time [WMD=7.65, 95%CI (4.41, 10.88), P<0.001], and the difference was statistically significant. There was no statistically significant difference between the two groups in terms of re ablation rate [OR=1.17, 95%CI (0.59, 2.31), P=0.65] and acute surgical success rate [OR=0.86, 95%CI (0.22, 3.35), P=0.82]. ConclusionCompared with RFA, PFA treatment for atrial fibrillation can reduce the recurrence rate, shorten the surgical time, and reduce surgical complications, indicating its good effectiveness and safety in the treatment of atrial fibrillation.
ObjectiveTo compare the clinical efficacy of endoscopic minimally invasive surgery and median sternotomy thoracotomy in the treatment of atrial myxoma by meta-analysis.MethodsWe searched CBM, CNKI, Wanfang Data, VIP, PubMed, the Cochrane Library and EMbase to collect relevant researches on atrial myxoma and endoscopic minimally invasive surgery. The retrieval time was from the establishment of the database to September 2020. Two reviewers independently screened the literature, extracted data and evaluated the bias risk of included studies by the Newcastle-Ottawa scale (NOS). Then, the meta-analysis was performed by Stata 16.0.ResultsTen articles were included in the study, all of which were case-control studies. The quality of literature was grade B in 5 articles and grade A in 5 articles. The sample size of surgery was 938 patients, including 480 patients in the endoscopic minimally invasive group, 458 patients in the median thoracotomy group, and 595 patients in follow-up. A total of 18 outcome indexes were included in the meta-analysis. The combined results of 9 outcome indicators were statistically significant: cardiopulmonary bypass time (SMD=0.32, 95%CI 0.00 to 0.63, P=0.048); ventilator assisted ventilation time (SMD=?0.35, 95%CI ?0.56 to ?0.15, P=0.001), ICU stay time (SMD=–0.42, 95%CI ?0.62 to ?0.21, P<0.001); postoperative hospitalization time (SMD=?0.91, 95%CI ?1.22 to ?0.60, P<0.001); postoperative drainage volume (SMD=?2.48, 95%CI ?5.24 to 0.28, P<0.001); postoperative new onset atrial fibrillation (OR=0.29, 95%CI 0.12 to 0.67, P= 0.005); postoperative pneumonia (OR=0.09, 95%CI 0.02 to 0.36, P=0.001); postoperative blood transfusion (OR=0.22, 95%CI 0.11 to 0.45, P<0.001); incision satisfaction (OR=83.15, 95%CI 1.24 to 5563.29, P=0.039).ConclusionAvailable evidence suggests that median thoracotomy requires shorter cardiopulmonary bypass time than endoscopic minimally invasive surgery; during the 5-year follow-up after surgery and discharge, ICU stay time, postoperative hospital stay, postoperative drainage, new atrial fibrillation after surgery, postoperative pneumonia, postoperative blood transfusion, satisfactory incision, endoscopic minimally invasive surgery showed better results than median sternotomy thoracotomy.
ObjectiveTo compare the postoperative enhanced recovery outcomes of lobectomy performed under non-intubated video-assisted thoracic surgery (NIVATS) versus intubated video-assisted thoracic surgery (IVATS). Methods Computerized searches were performed in the following databases: China National Knowledge Infrastructure (CNKI), Wanfang Data, VIP Information, China Biomedical Literature Database (CBMdisc), Web of Science, Clinicaltrials.gov, The Cochrane Library, EMbase, and PubMed. We collected randomized controlled trials (RCTs) and observational studies comparing NIVATS and IVATS. The search period extended from the inception of each database to April 1, 2023. Two independent researchers screened the literature and assessed study quality. ResultsA total of 14 studies were included, comprising 4 RCTs, 7 retrospective cohort studies, and 3 propensity score matching studies, involving 1 840 patients. Meta-analysis results indicated that, compared to IVATS, NIVATS was associated with significantly shorter operative time [MD=–13.39, 95%CI (–20.16, –6.62), P<0.001], shorter length of hospital stay [MD=–0.81, 95%CI (–1.39, –0.22), P=0.005], shorter chest tube duration [MD=–0.73, 95%CI (–1.36, –0.10), P=0.02], shorter postoperative anesthesia recovery time [MD=–20.34, 95%CI (–26.83, –13.84), P<0.001], and shorter time to oral intake after surgery [MD=–5.68, 95%CI (–7.63, –3.73), P<0.001]. Furthermore, NIVATS showed a lower incidence of postoperative airway complications [OR=0.49, 95%CI (0.34, 0.71), P<0.001] and less total chest tube drainage volume [MD=–251.11, 95%CI (–398.25, –103.98), P<0.001], all contributing to significantly accelerated postoperative enhanced recovery for patients. Conclusion NIVATS is a safe and technically feasible anesthesia method in thoracoscopic lobectomy, which can to some extent replace IVATS.
ObjectiveTo systematically evaluate the efficacy of tubular stomach and whole stomach reconstruction in the treatment of esophageal cancer.MethodsWe searched PubMed, Web of Science, The Cochrane Library, EMbase, CNKI, Wanfang Data, VIP and CBM databases to collect the randomized controlled trial (RCT) studies on the efficacy comparison between tubular stomach and total gastric reconstruction of esophagus in esophagectomy from their date of inception to May 2019. Then meta-analysis was performed by using RevMan 5.3 software.ResultsA total of Twenty-nine RCTs were included, and 3 012 patients were involved. The results of meta-analysis showed that the postoperative complications such as anastomotic fistula [RR=0.64, 95%CI (0.50, 0.83), P=0.000 6], anastomotic stenosis [RR=0.65, 95%CI (0.50, 0.86), P=0.002], thoracic gastric syndrome [RR=0.19, 95%CI (0.13, 0.27), P<0.001], reflux esophagitis [RR=0.23, 95%CI (0.19, 0.30), P<0.001], gastric emptying disorder [RR=0.39, 95%CI (0.27, 0.57), P<0.001] and pulmonary infection [RR=0.44, 95%CI (0.31, 0.62), P<0.001] were significantly reduced, and the postoperative quality of life score and satisfaction were higher at 6 months and 1 year in the tubular stomach group (P<0.05). In terms of intraoperative blood loss and postoperative hospital stay, they were better in the tubular stomach group than those in the whole stomach group (P<0.05). However, there was no statistically significant difference between the two groups in operation time, postoperative gastrointestinal decompression time, postoperative closed drainage time, postoperative 1-year, 2-year and 3-year survival rate, postoperative quality of life score at 3 weeks and 3 months, and postoperative life satisfaction at 3 weeks.ConclusionThe tubular stomach is more advantageous than the whole stomach in the reconstruction of esophagus after esophagectomy.
