ObjectiveTo investigate the effects of two different oxygen therapies (oxygen time<4 h/d, oxygen flow>6 L/min versus oxygen time>4 h/d, oxygen flow<6 L/min) on conservative treatment of spontaneous pneumothorax by meta-analysis.MethodsThe following electronic databases as PubMed, The Cochrane Library, Web of Science, Chinese Biomedical Literature Database, WanFang Database and China National Knowledge Database were retrieved on computer for randomized controlled trials (RCTs) of comparing two different oxygen therapies (oxygen time<4 h/d, oxygen flow>6 L/min versus oxygen time>4 h/d, oxygen flow<6 L/min) on conservative treatment of spontaneous pneumothorax. The retrieval time was from inception of each database to December 2017. Two reviewers independently screened literature according to the inclusion and exclusion criteria, extracted data, and assessed the methodological quality of the included studies. Then data were analyzed by RevMan 5.3 software.ResultsA total of 4 RCTs involving 226 patients were included. The meta-analysis showed that compared with lower oxygen flow (oxygen time>4 h/d, oxygen flow<6 L/min), the higher oxygen flow (oxygen time<4 h/d, oxygen flow>6 L/min) could obviously decrease the degree of pulmonary compression after oxygen therapy for 5 days (MD=–2.81, 95%CI –4.18 to –1.44, P<0.05), shorten duration of hospital stay (MD=–3.26, 95%CI –6.05 to –0.47, P<0.05) and duration of recruitment maneuvers (MD=–2.78, 95%CI –5.27 to –0.28, P<0.05), but there was no significant difference in oxygen partial pressure after oxygen therapy for 5 days (MD=10.68, 95%CI –7.03 to 28.39, P=0.24).ConclusionThe higher oxygen flow (oxygen time<4 h/d, oxygen flow>6 L/min) can obviously decrease the degree of pulmonary compression after oxygen therapy for 5 days, shorten duration of hospital stay and duration of recruitment maneuvers, but the results are influenced by the number and quality of RCT.
ObjectiveTo investigate the optimal treatment scheme for the first primary spontaneous pneumothorax (PSP) in young patients.MethodsThe clinical data of 171 patients with the first PSP were retrospectively analyzed who were treated in Huaihe Hospital of Henan University between November 2011 and October 2017. There were 157 males and 14 females with a median age of 18 years at onset and a median body mass index of 18.51 kg/m2. According to the treatment methods, they were classified into two groups, a conservative treatment group (a non-surgical group, n=86) and a surgical group (n=85). The characteristics including clinical data, efficacy evaluation criteria, complications and recurrence of the two groups were analyzed.ResultsAs a result, 73.68% of the patients suffered PSP in their daily routine. The drainage duration in the non-surgical group was longer than that in the surgical group (4 d vs. 3 d, P=0.008). There was no statistical difference in the success rate of lung re-expansion between the two groups (98.85% vs. 100.00%, P=1.000). The proportion of the surgical group using postoperative analgesic drugs was higher than that in the non-surgical group (48.23% vs. 10.46%, P=0.000). The recurrence rate of the surgical group was lower than that of the non-surgical group (3.53% vs. 46.51%, P=0.000). No relationship between smoking and recurrence of pneumothorax was found in both groups (P=0.301, P=1.000). The success rate of lung re-expansion in the non-surgical group was not statistically different between the 24F subgroup and the 12F subgroup (39/39 vs. 33/34, P=0.458). No advantage of intraoperative pleural fixation was found in the surgical group (P=0.693).ConclusionThoracoscopic surgery is the first choice for the treatment of the first PSP in young patients.
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.
Objective To evaluate the incidence and characteristics of spontaneous pneumothorax in patients with Marfan syndrome (MFS), and to analyze its related factors. Methods The medical record of patients with MFS who were hospitalized in the First Affiliated Hospital of University of Science and Technology of China from March 1, 2017 to December 31, 2022 were retrospectively collected, to analyze the incidence of pneumothorax and related risk factors. Results A total of 53 patients (including 29 males, 55%) were included, with a median age of 32 years (ranging from 13 to 65 years). All patients denied family history of pneumothorax. Four cases (8%) had one episode of spontaneous pneumothorax, with pulmonary bullae involved the ipsilateral apex. Among them, 3 cases (75%) had single pulmonary bulla and thoracic deformity. Of the 49 patients without previous pneumothorax history, 9 (18%) had pulmonary bullae, of which 6 (67%) were located at the apex of the lung, and the remaining 3 (33%) were in the middle and lower lobes of the lung; In addition, 6 cases (12%) were coexisted with thoracic deformity. The incidence of pneumothorax in patients with pulmonary bullae in MFS was significantly higher than those without pulmonary bullae (31% vs. 0%, P=0.002), and the incidence of pneumothorax in patients with thoracic deformities was significantly higher than those with normal thorax (33% vs. 2%, P=0.013). Of the 4 patients with pneumothorax, 2 underwent bullectomy, 1 underwent thoracic drainage, and the other underwent thoracic puncture and aspiration procedures, respectively. No recurrence of pneumothorax was observed during the follow-up period. Sixteen cases of MFS with spontaneous pneumothorax (11 males, 69%) were reported in Chinese literature, with a median age of 17 years (ranging from 13 to 28 years). Among them, 3 cases (19%) had a family history of pneumothorax, and 14 cases (88%) had thoracic deformities. Bullae was found in all 5 patients with pneumothorax, 4 of them with chest CT images involved the ipsilateral upper lobe. Forty-four percents of 16 patients had pneumothorax recurrence. Conclusions The incidence of MFS complicated with spontaneous pneumothorax is significantly higher. However, most of them have no family history of pneumothorax. The incidence of pneumothorax with MFS is associated with pulmonary bullae (especially the apex of lung) and thoracic deformity. Timely surgical intervention should be carried out when pneumothorax happened.
Objective To systematically evaluate the efficacy and safety of Single-incision thoracoscopic surgery (SITS) and two-port video-assisted thoracoscopic surgery (2P-VATS) in the treatment of spontaneous pneumothorax. Methods The databases of CNKI, PubMed, The Cochrane Libray, Web of Science, EMbase, Wanfang and Chinese Medical Association were searched by computer. Literature on SITS treatment of spontaneous pneumothorax from the establishment of the database to March 2023. The data are processed with RevMan 5.4.1. Results Finally, 107 studies were included, including 35 RCTs, 2 cohort studies, and 70 case-control studies. Meta analysis results show that compared to 2P-VATS and three port video assisted thoracoscopic surgery (3P-VATS), SITS had a shorter surgical time [SMD=–0.53, 95%CI (–0.90, –0.16), P=0.005], less intraoperative bleeding [SMD=–1.58, 95%CI (–1.93, –1.22), P<0.000 01; SMD=–1.59, 95%CI (–2.03,–1.14), P<0.000 01], shorter postoperative hospitalization time [SMD=–1.05, 95%CI (–1.29,–0.82), P<0.000 01; SMD=–1.08, 95%CI (–1.39,–0.77), P<0.000 01], and shorter postoperative drainage (catheterization) time [SMD=–0.75, 95%CI (–1.00,–0.50), P<0.000 01; SMD=–1.23, 95%CI (–1.72,–0.75), P<0.000 01], fewer postoperative complications [OR=0.34, 95%CI (0.26,0.45), P<0.000 01; OR=0.47, 95%CI (0.33,0.68), P<0.000 1], fewer postoperative recurrences [OR=0.50, 95%CI (0.33,0.75), P=0.000 8], and lighter postoperative pain [SMD=–1.71, 95%CI (–1.98,–1.45), P<0.000 01; SMD=–2.02, 95%CI (–2.46,–1.59), P<0.000 01]. Compared with 3P-VATS, 2P-VATS had less intraoperative bleeding [SMD=–1.02, 95%CI (–1.81,–0.22), P=0.01] , shorter postoperative hospitalization time [SMD=–0.59, 95%CI (–1.11,–0.06), P=0.03], shorter postoperative drainage (catheterization) time [SMD=–0.46, 95%CI (–0.85,–0.08), P=0.02], fewer postoperative complications [OR=0.36, 95%CI (0.22,0.59), P<0.000 1] , and lighter postoperative pain [SMD=–0.80, 95%CI (–1.08,–0.53), P<0.000 01]. Conclusion SITS and 2P-VATS are an effective and safe method for the treatment of spontaneous pneumothorax and worthy of further promotion and application in clinical practice. Due to limitations in the quantity and quality of included studies, the above conclusions require more large-sample, high-quality studies to be verified.
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.
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 evaluate the efficacy, safety, and long-term recurrence rate of thoracoscopic bullae resection combined with parietal pleurectomy or pleural abrasion for the treatment of spontaneous pneumothorax. MethodsRelevant literatures were searched in PubMed, Web of Science, EMbase, The Cochrane Library, CNKI, Wanfang and VIP databases from the establishment of each database to February 1, 2025. According to the inclusion and exclusion criteria, the literatures were screened. Meta-analysis was conducted using Review Manager 5.3 software, and the quality of the literatures was evaluated using the Cochrane Bias Risk Assessment Tool and the NOS scale. ResultsA total of 23 articles were included, including 6 randomized controlled studies and 17 retrospective cohort studies, with NOS scores≥7. A total of 3 296 patients were enrolled, including 1 245 in the parietal pleurectomy group and 2 051 in the pleural abrasion group. The meta-analysis results showed that the pleural abrasion group had shorter operation time [MD=19.68, 95%CI (14.12-25.25)], less intraoperative blood loss [MD=11.31, 95%CI (4.20-18.41)], lower postoperative pain score [MD=0.48, 95%CI (0.04-0.91)], lower total postoperative drainage volume [MD=44.31, 95%CI (11.92-76.71)], shorter postoperative drainage time [MD=0.32, 95%CI (0.03-0.60)], and shorter hospital stay [MD=0.40, 95%CI (0.23-0.57)] compared with the parietal pleurectomy group, and the differences were statistically significant (P<0.05). In terms of safety, the parietal pleurectomy group increased the incidence of postoperative pulmonary hemorrhage [OR=3.99, 95%CI (1.49-10.65), P<0.05], but there were no statistically significant differences in the incidence of postoperative atelectasis, pneumothorax leakage and pulmonary infection (P>0.05). In addition, the parietal pleurectomy group could effectively reduce the long-term recurrence rate of patients [OR=0.48, 95%CI (0.36-0.64)], and the difference was statistically significant (P<0.05). ConclusionDecortication inevitably imposes a greater perioperative burden on patients with spontaneous pneumothorax and pulmonary bullae, yet it effectively reduces the risk of postoperative recurrence. While both surgical approaches exhibit similar safety profiles, parietal pleurectomy may elevate the risk of postoperative pulmonary hemorrhage. Therefore, the optimal treatment strategy should be determined based on individual patient characteristics.
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.
