ObjectiveTo evaluate the clinical efficacy of central venous catheter closed drainage of pleural cavity combined with negative pressure suction in the treatment of spontaneous pneumothorax. MethodsThe randomized controlled trials(RCTs) on central venous catheter closed drainage of pleural cavity combined with negative pressure suction in the treatment of spontaneous pneumothorax were searched in PubMed, OVID, CNKI, Wangfang database, Super Star Digital Library, CMB, Baidu and Google search engines. The searching time was from the time of building database to September 15, 2014. Two searchers selected studies based on the included criteria strictly. The quality of RCTs was appraised by the criteria of Cochrane Collaboration. RevMan5.3 software was used for data analysis and management. ResultsA total of 18 RCTs including 1 549 patients were identified. There were no statistical differences in time of lung recruitment (SMD=0.01 and 95%CI -0.23 to 0.25, P=0.95), time of hospital stay (SMD=-0.42, 95%CI -1.81 to 0.97, P=0.55), curative resection rate (RR=1.04 and 95%CI 1.00 to 1.08, P=0.07) between the two groups. The rate of complications in the central venous catheter group was less than that in the conventional pleural cavity closed drainage group with a statistical difference (RR=0.31, 95%CI 0.23 to 0.43, P<0.000 01). ConclusionThe treatment of central venous catheter closed drainage of pleural cavity combined with negative pressure suction for spontaneous pneumothorax is a simple and safe operation. However, the quality of studies included is not high and some sample size is small. RCTs with large sample of high quality are still needed for further confirmation.
ObjectiveTo explore clinical outcomes of simutaneous video-assisted thoracoscopic surgery (VATS) for bilateral giant bullae (GB). MethodsClinical data of 160 GB patients who received surgical treatment in the First Affiliated Hospital of Xinjiang Medical University from March 2011 to April 2013 were retrospectively analyzed. According to GB location and surgical strategies, all the patients were divided into 3 groups. In group A, there were 108 patients with spontaneous pneumothorax (SP) and unilateral GB who underwent unilateral GB resection with VATS, including 88 male and 20 female patients with their age of 31.36±16.14 years. In group B, there were 40 patients with SP and bilateral GB who underwent unilateral GB resection in the SP side with VATS, including 36 male and 4 female patients with their age of 37.63±18.84 years. In group C, there were 12 patients with SP and bilateral GB who underwent simultaneous bilateral GB resection with VATS, including 9 male and 3 female patients with their age of 32.58±16.06 years. Postoperative morbidity and SP recurrence rates were analyzed. ResultsAll the operations were successfully performed, and patients were followed up for 20 months after discharge. In group A, postoperative complications included acute pulmonary edema in 1 patient, pleural adhesion in 11 patients, respiratory failure in 2 patients, and pulmonary air leak in 5 patients. During follow-up, SP recurred in 5 patients including 2 patients with SP recurrence at the same side and 3 patients with SP recurrence at the other side of thorax. In group B, postoperative complications included pleural adhesion in 4 patients, respiratory failure in 1 patient, and pulmonary air leak in 3 patients. During follow-up, SP recurred in 18 patients including 3 patients with SP recurrence at the same side and 15 patients with SP recurrence at the other side of thorax. In group C, postoperative complications included pleural adhesion in 2 patients and pulmonary air leak in 1 patient. During follow-up, SP recurred in 1 patient at the same side of thorax. SP recurrence rates of group A and C were significantly lower than that of group B (P=0.000 and P=0.031 respectively). ConclusionSimultaneous VATS is safe, efficacious and reliable for the treatment of bilateral GB, and can effectively prevent SP recurrence at the other side of thorax.
ObjectiveTo explore the surgical procedures for primary spontaneous pneumothorax without bullae. MethodsWe retrospectively analyzed the clinical data of 52 patients with primary spontaneous pneumothorax without bullae, who underwent surgical treatment in Second Affiliated Hospital of Kunming Medical University between January 2008 and January 2013. There were 46 males and 6 females, with mean average age of 23.2±4.3 years (ranged from 16 to 34 years). According to the different methods of intraoperative surgery, all patients were divided into three groups. The patients in a group Ⅰ (n=20) underwent video-assisted thoracoscope (VATS) selective apex of low energy electric coagulation treatment. The patients in a group Ⅱ (n=21) underwent VATS lung tip part of lung resection. The patients in a group Ⅲ (n=11) received VATS resection of the pleura. The clinical effectiveness among the three groups was compared. ResultsCompared with other two kinds of operation schemes,the leak duration(2.61±1.89 d vs. 4.90±3.20 d vs. 5.36±2.57 d, P=0.012), postoperative chest tube drainage time (3.67±2.13 d vs. 6.00±3.73 d vs. 7.03±2.58 d, P=0.003), postoperative length of hospital stay (4.95±2.16 d vs. 7.35±3.03 d vs. 8.61±2.67 d, P=0.002) and the recurrence rate (0.0% vs. 23.1% vs. 12.5%, P=0.021) of the patients with lung tip part resection of lung tissue by VATS were significantly lower. There were no statistically significant differences in the indicators of the patients with selective apex of low energy electric coagulation by VATS and those with pleural resection by VATS (P>0.05). ConclusionLung tip part of the lung tissue resection by VATS for primary spontaneous pneumothorax without bullae is better than VATS selective apical low energy coagulation treatment and VATS resection of the pleura both in the short and long-term efficacy.
Objective To explore clinical efficacy and independent risk factors related to the recurrence of primary spontaneous pneumothorax (PSP) after video-assisted thoracoscopic surgery (VATS). Method We retrospectively anal- yzed the clinical data of 566 PSP patients by VATS in our hospital between December 2011 and June 2014 year. The patients were divided into a triple-port group(110 patients with 88 males and 22 females, aged 31.34±15.62 years) and a double-port group (456 patients with 383 males and 73 females, aged 31.46±15.65 years) by operation methods. We tried to find out the independent risk factors related to the recurrence. Results There was no statistical difference in intraoperative blood loss, postoperative drainage, drain removal, postoperative complications, postoperative length of hospital stay and rate of postoperative recurrence between the two groups (P>0.05) . However, the operation time (P<0.001) and the drainage of postoperative 48 hours (P<0.05) in the double-port group was shorter or less than that in the triple-port group. The overall recurrence rate was 1.41% (8/566) . The minors (OR=14.75, P=0.045) , no bulla type (OR=32.76, P=0.019) , and multiple bulla type (OR=15.48, P=0.013) were the independent risk factors for postoperative recurrence. Conclusions The double- port VATS technique has similar effect with triple-port VATS technique on spontaneous pneumothorax patients under- gone pulmonary bullae ligation and pleurodesis. Bulla ligation and whole mechanical pleurodesis can get better clinical efficacy and lower rate of recurrence. The minor, no bulla type, and multiple bulla type are the independent recurrence risk factors of PSP after surgery.
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 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 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.
Objective To evaluate whether surgical intervention can be performed in initial onset of primary spontaneous pneumothorax (PSP) patients and whether pleural abrasion should be performed regularly in PSP treatment. Methods The clinical data of 326 PSP patients undergoing bullectomy or bullectomy combined with pleural abrasion (BLPA) between January 2008 and December 2013 were retrospectively reviewed. There were 267 males and 59 females, with a mean age of 24 years ranging from 20 to 31 years. Results The initial onset of PSP was in 229 patients, and recurrent PSP in 115 patients. Ten patients had postoperative PSP recurrence after a mean follow-up of 47 months ranging from 1 to 95 months. For the patients with initial onset of PSP, the recurrence rate was 3.1% (7/229), and that in patients with recurrent PSP was 2.6% (3/115, P=0.82). Compared with the bullectomy group (5.8%, 7/120), recurrence rate in the BLPA group was lower (1.3%, 3/224, P=0.02). There were no mortalities or significant complications in both groups. There was significant difference in body mass index (P=0.04), intraoperative adhesion (P<0.05), operation duration (P<0.01), number of bullae (P<0.01), and bullae location (P<0.01) between bullectomy and BLPA groups. Postoperative drainage (P<0.01), air leak (P=0.01) and extubation duration (P<0.01) were significantly lower in the bullectomy group. Total cost was significantly higher in the BLPA group (P<0.01). Conclusion Surgical intervention could provide satisfactory outcomes for PSP patients. Compared with bullectomy, BLPA has much lower recurrence rate, but with more drainage, longer drainage duration and higher cost.
