ObjectiveTo systematically review the clinical effects and safety of thoracoscopy operation and thoracotomy for spontaneous pneumothorax. MethodsWe searched PubMed, EMbase, The Cochrane Library (Issue 10, 2013), Web of Knowledge, CNKI, CBM, WanFang Data and VIP up to October 2013. Randomized controlled trials involving treatment outcomes of spontaneous pneumothorax using thoracoscopy compared with thoracotomy were included. Two reviewers independently screened literature according to the inclusion and exclusion criteria, extracted data, and assessed the methodological quality of the included studies. Then RevMan 5.2 software was used for meta-analysis. ResultsA total of 7 studies involving 481 patients were included. The results of meta-analysis showed that the operative time in the thoracoscopy goup was significantly longer than that in the thoracotomy group (MD=13.57, 95%CI 3.58 to 23.56, P=0.008). But there was no significant difference in recurrence rates (RR=3.16, 95%CI 0.84 to 11.94, P=0.09), total postoperative complications (RR=1.33, 95%CI 0.46 to 3.88, P=0.46), postoperative chest drainage time (MD=-0.00, 95%CI-0.64 to-0.63, P=0.99), and hospitalization time (MD=0.09, 95%CI-0.21 to 0.40, P=0.55). ConclusionCompared with thoracotomy, thoracoscopy does not increase recurrence rates, postoperative complications, chest drainage time or hospitalization time, but it could prolong operation time in a certain extent.
ObjectiveTo systematically review the complications and quality of life (QoL) in patients with esophageal cancer after esophagectomy using gastric tube. MethodsRandomized controlled trials (RCTs) about the postoperative complications and QoL of patients using gastric tube and the whole stomach reconstruction were electronically searched in PubMed, EMbase, The Cochrane Library, Web of Knowledge, CBM, CNKI, VIP and WanFang Data from inception to September 30th, 2013. Two reviewers independently screened literature according to the inclusion and exclusion criteria, extracted data, and assessed methodological quality. Then meta-analysis was performed using RevMan 5.2 software. ResultsA total of 10 RCTs involving 1 085 patients were included. The results of meta-analysis showed that, in terms of postoperative complications, the incidences of reflux esophagitis (OR=0.19, 95%CI 0.12 to 0.32, P < 0.000 01) and intrathoracic stomach syndrome (OR=0.11, 95%CI 0.04 to 0.32, P < 0.000 1) with gastric tube were significantly lower than those of the whole stomach; in terms of QoL, the scores of QoL in the 6th month (MD=18.71, 95%CI 7.72 to 29.71, P=0.000 9) and in the 12th month (MD=22.95, 95%CI 8.21 to 37.69, P=0.002) with gastric tube were significantly higher than those of the whole stomach. In terms of satisfaction degree of QoL, the satisfaction degree of QoL in the 6th month (OR=1.78, 95%CI 1.10 to 2.88, P=0.02) and the 12th month (OR=2.73, 95%CI 1.67 to 4.47, P < 0.000 1) with gastric tube were both significantly higher than those of the whole stomach. ConclusionCompared with the whole stomach reconstruction, the method of gastric tube reconstruction has beneficial effects in reducing the incidences of postoperative complications (such as reflux esophagitis, intrathoracic stomach syndrome) and improves patients' QoL. But there are many uncertain factors about postoperative anastomotic complication and its influence on patients' long-term QoL remains uncertain. Thus, further studies should be conducted.
ObjectiveTo systematically evaluate the effects of closed drainage and simply closed drainage combined with pleurodesis in the treatment spontaneous pneumothorax. MethodsWe searched PubMed, Web of Science, The Cochrane Library, CBM, WanFang Data and CNKI from their inception to December 2nd, 2014, to collect randomized controlled trials (RCTs) of simple closed drainage versus closed drainage combined with pleurodesis in the treatment of spontaneous pneumothorax. Two reviewers independently screened literature according to the inclusion and exclusion criteria, extracted data and evaluated the risk of bias of included studies. Then, RevMan 5.3 software was used for meta-analysis. ResultsA total of 5 RCTs including 499 patients were included. The results of meta-analysis showed that:Compared with the simple closed drainage, the closed drainage combined with pleurodesis was superior in the effective rate of recurrence spontaneous pneumothorax (OR=6.85, 95%CI 3.26 to 14.39, P<0.000 01) and the recurrence rate of primary spontaneous pneumothorax (OR=0.32, 95%CI 0.18 to 0.57, P<0.001). But there were no statistical differences in both groups in the effective rate of primary spontaneous pneumothorax (OR=1.49, 95%CI 0.71 to 3.14, P=0.29), the hospital stays of primary spontaneous pneumothorax (SMD=0.08, 95%CI -0.16 to 0.31, P=0.52), the hospital stays of recurrence spontaneous pneumothorax (SMD=-1.67, 95%CI -3.96 to 0.61, P=0.15), and the duration of drainage of primary spontaneous pneumothorax (SMD=-0.11, 95%CI 0.79 to 0.58, P=0.76). ConclusionCurrent evidence suggests that closed drainage combined with pleurodesis could improve the effective rate of recurrence spontaneous pneumothorax and decrease the recurrence rate of primary spontaneous pneumothorax. Due to limited quantity and quality of included studies, the above conclusion should be validated by more high quality studies.
ObjectiveTo systematically review the efficacy of clinical nursing pathway (CNP) in patients with esophageal cancer surgery. MethodsDatabases including PubMed, EMbase, The Cochrane Library, Web of Science, CBM, WanFang Data and CNKI were electronically searched to collect randomized controlled trials (RCTs) involving the comparison of CNP with routine nursing pathway in patients with esophageal caner surgery. The retrieval time was from inception to October 2014. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Then data was analyzed by RevMan 5.2 software. ResultsA total of 16 RCTs involving 1 457 patients were included. The results of meta-analyses showed that:compared with the routine nursing pathway, the CNP could increase patients' nursing satisfaction (OR=8.08, 95%CI 5.12 to 12.74, P<0.000 01), the achievement rate of knowledge (OR=4.13, 95%CI 2.44 to 6.98, P<0.000 01) and decrease the incidence of postoperative complications (OR=0.21, 95%CI 0.13 to 0.33, P<0.000 01), the length of hospitalization (MD=-4.57, 95%CI -5.57 to -3.56, P<0.000 01). ConclusionThe clinical nursing pathway can improve patients' nursing satisfaction, the achievement rate of knowledge, it can also reduce the incidence of postoperative complications and the length of hospitalization.
Objective To systematically review the effectiveness of thoracoscopy surgery and thoracotomy for thymoma. Methods Databases including PubMed, EMbase, The Cochrane Library (Issue 3, 2016), Web of Science, CBM, WanFang Data and CNKI were searched to collect randomized controlled trials (RCTs) and cohort studies about thoracoscopy surgery versus thoracotomy for thymoma from inception to April 2016. Two reviewers independently screened literature, extracted data, and assessed the risk of bias of included studies. Then meta-analysis was performed using RevMan 5.3 software. Results A total of 5 RCTs and 8 cohort studies involving 1 093 patients were included. The results of meta-analysis showed that, compared with thoracotomy, the thoracoscopy surgery could shorten operative time (MD= –22.2, 95%CI –32.92 to –12.52, P < 0.000 01), duration of ICU stay (MD= –0.76, 95%CI –0.21 to –0.30, P < 0.000 01), duration of hospital stay (MD= –3.71, 95%CI –4.47 to –2.96, P < 0.000 01) and duration of pleural drainage (MD= –1.80, 95%CI –2.42 to –1.18, P < 0.000 01), reduce volume of intraoperative blood loss (MD= –43.27, 95%CI –50.94 to –35.60, P < 0.000 01), and decrease the incidence of postoperative complications (OR=0.19, 95%CI 0.11 to 0.34, P < 0.000 01), but there was no significant difference in recurrence rate between two groups (OR=0.81, 95%CI 0.31 to 2.11, P=0.67). Conclusions Current evidence shows that, compared with thoracotomy, the thoracoscopy surgery for thymoma has shorter operative time, duration of ICU stay, duration of hospital stay, and duration of pleural drainage, as well as less blood loss and postoperative complications. Due to the limited quality of included studies, more high-quality studies are needed to verify the above conclusion.
ObjectiveTo systematically review the efficacy and safety of laparoscopic Heller's myotomy (LHM) versus pneumatic dilatation (PD) for achalasia. MethodsDatabases including PubMed, EMbase, The Cochrane Library (Issue 8, 2015), Web of Knowledge, CNKI, CBM, WanFang Data and VIP were searched from inception to August 26th 2015, to collect randomized controlled trials (RCTs) of LHM versus PD for achalasia. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Then, meta-analysis was performed using RevMan 5.3 software. ResultsA total of 5 RCTs involving 446 patients were included. The results of meta-analysis showed that, compared with PD, LHM could significantly improve the effective rates after 3-month and 1-year follow-up (OR=2.66, 95%CI 1.08 to 6.60, P=0.03; OR=2.24, 95%CI 1.29 to 3.87, P=0.004). There were no statistical differences between the two groups in effective rate after more than 2-year follow-up (OR=1.749, 95%CI 0.99 to 3.23, P=0.05) and incidence of complications (OR=0.27, 95%CI 0.06 to 1.13, P=0.07). ConclusionCurrent evidence shows that, compared with PD, LHM could improve the short-term effective rate but could not improve the long-term (2-3 years) effective rate and reduce the incidence of complications. Due to limited quality and quantity of the included studies, more high quality studies are needed to verify the above conclusion.
ObjectiveTo systematically review the impact of side-to-side esophagogastric anastomosis on postoperative anastomostic leak, fibrosis stricture and stroesophageal reflux. MethodsWe searched PubMed, EMbase, The Cochrane Library (Issue 4 2015), Web of Science, CNKI, CBM, Wanfang Database and VIP up to April 2015. Randomized controlled trials involving the complications after side-to-side esophagogastric anastomosis were included. Data were extracted and methodological quality was evaluated by two reviewers independently with a designed extraction form. Then RevMan 5.3 software was used for meta-analysis. ResultsA total of 7 studies involving 684 patients were included. The results of meta-analysis showed that comparing with traditional anastomosis, side-to-side esophagogastric anastomosis could reduce the incidence of fibrosis stricture with RR=0.20 and 95% CI 0.11 to 0.36 (P<0.000 01). There was no statistical difference in incidence of postoperative anasotmostic leaks with RR=0.71 and 95% CI 0.43 to 1.19 (P=0.19) or stroesophageal reflux with RR=0.74 and 95% CI 0.50 to 1.11 (P=0.15) between the two groups. ConclusionComparing with traditional anastomosis, side-to-side esophagogastric anastomosis could reduce the incidences of fibrosis stricture, but there is no statistical difference in anastomostic leak or stroesophageal reflux.
ObjectiveTo systematically review the efficacy of early enteral nutrition (EN) versus parenteral nutrition (PN) for esophagus cancer patients after esophagectomy. MethodsThe following electronic databases as PubMed, EMbase, The Cochrane Library (Issue 6, 2016), Web of Science, CBM, WanFang Data and CNKI were searched from inception to June 2016 to collect randomized controlled trials (RCTs) on comparing early EN and PN for esophagus cancer patients after esophagectomy. Two reviewers independently screened literature according to the inclusion and exclusion criteria, extracted data, and assessed the risk of bias of included studies. Then meta-analysis was performed by using RevMan 5.3 software. ResultsA total of 14 RCTs involving 2 275 patients were included. The results of meta-analysis showed that, compared with the PN group, the early EN group could improve postoperative levels of albumin (MD=1.12, 95%CI 0.03 to 2.20, P=0.04) and transferrin (MD=10.08, 95%CI 5.41 to 14.76, P<0.000 1), decrease the incidences of pulmonary infection (OR=0.36, 95%CI 0.25 to 0.53, P<0.000 01) and anastomotic leakage (OR=0.57, 95%CI 0.36 to 0.92, P=0.02), but there was no significant difference in postoperative level of prealbumin between two groups (MD=10.04, 95%CI -0.31 to 20.39, P=0.06). ConclusionThe early EN could improve the postoperative levels of albumin and transferrin, decrease the incidences of pulmonary infection and anastomotic leakage, but could not improve the postoperative prealbumin level.
