Simultaneous Viscum pleurodesis and video-assisted thoracic surgery (VATS) bullectomy in patients with primary spontaneous pneumothorax.

ABSTRACT: Although surgery is the gold standard for treatment of primary spontaneous pneumothorax (PSP), recurrence after surgery remains a concern. This study sought to evaluate the efficacy of simultaneous pleurodesis using Viscum album (VA) extract and video-assisted thoracic surgery (VATS) bullectomy for the treatment of PSP. From March 2016 to June 2020, 175 patients with PSP underwent bullectomy and intraoperative pleurodesis with VA extract at a single institution. All operations were performed through thoracoscopy by one surgeon. Upon completion of bullectomy, a polyglycolic acid sheet was used to cover the stapler lines, and 40 mg of VA extract was instilled over the entire chest wall before chest tube placement. The median operating time was 20 min (interquartile ranges, 15-30) and the median indwelling time of chest drainage was 2 days (interquartile ranges, 2-3). There were no postoperative complications over grade 3. During the median follow-up period of 38 months (interquartile ranges, 15-48), no recurrence of pneumothorax was observed. The results of this study demonstrated that simultaneous Viscum pleurodesis and VATS bullectomy provides a feasible and effective treatment option for preventing postoperative pneumothorax in patients with PSP.

Project description:BackgroundPrimary spontaneous pneumothorax is managed initially with observation and chest tube placement, followed by surgical intervention in select cases. With little currently published evidence, the role of surgical pleurodesis or pleurectomy to reduce primary spontaneous pneumothorax recurrence is unclear. This study compares the recurrence rates of primary spontaneous pneumothorax following bullectomy alone versus bullectomy with pleurodesis or pleurectomy.MethodsA retrospective review was performed at a quaternary hospital for all patients undergoing surgery for primary spontaneous pneumothorax between June 2006 and December 2018. Patient demographics, disease severity, operative technique, and time between initial surgery and recurrence were recorded. Standard statistical techniques were used for univariable and multivariable analyses.ResultsOf 222 total included patients, 28 required a second surgery: 4 (1.8%) for prolonged air leak and 24 (10.8%) for recurrent pneumothorax. The median time from first to second surgery was 363 days and 35.7% of recurrences did not present until after two years. Age, sex, smoking, year of initial surgery, disease severity, and surgical technique did not significantly affect recurrence rate on univariable analysis. On multivariable analysis, the odds ratios of recurrence for bullectomy with mechanical pleurodesis or pleurectomy were respectively 0.82 and 0.15 (P=0.218), compared to bullectomy alone. Combined bullectomy, pleurectomy, and pleurodesis was most effective (0/18, 0%).ConclusionsBullectomy with pleurectomy and pleurodesis demonstrated a 0% recurrence rate for the treatment of primary spontaneous pneumothorax in this study. Statistical significance was not achieved in univariable or multivariable analyses comparing recurrence rates for the surgical approaches. A multi-center randomized controlled trial with longer follow-up than previously performed is needed to confirm these preliminary findings and optimize surgical management of primary spontaneous pneumothorax.

Project description:BackgroundWith the adoption of high-tech thoracoscopic surgical instruments, video-assisted thoracoscopic surgery (VATS) has gradually replaced traditional thoracotomy and is used in the clinical treatment of spontaneous pneumothorax.MethodsThe composite logic retrieval and Boolean logic retrieval methods were adopted for this meta-analysis. Databases such as PubMed, Medline, Cochrane Library, CNKI, Wanfang, VIP, and Google Scholar were searched using the combination of search terms "Video-assisted thoracoscopic surgery", "spontaneous pneumothorax", and "thoracotomy". Literatures which used video-assisted thoracoscopic surgery for spontaneous pneumothorax as the experimental group were screened. The software RevMan 5.3 provided by the Cochrane system was employed for meta-analysis.ResultsA total of 12 studies were included. After the meta-analysis, heterogeneity testing of the operation time in 8 studies showed that Tau2 =29.99, Chi2 =16.99, degrees of freedom (df) =7, I2=59%>50%, and the operation time of participants in the experimental group was considerably inferior to that of control group. The mean difference (MD) was -31.02, 95% confidence interval (95% CI: -36.07 to -25.97), Z=12.03, P<0.0001. The heterogeneity test of the length of hospital stay in 9 studies showed that Tau2 =4.41, Chi2 =122.58, df =8, I2=59%>50%, P<0.01, and the length of hospital stay of participants in the experimental group was remarkably shorter than that of the control group. The MD was -7.29, 95% CI: (-8.76 to -5.82), Z=9.74, and P<0.01. The heterogeneity test of the bleeding volume in 6 studies showed that Tau2 =191.74, Chi2 =27.65, df =5, I2=82%>50%, P<0.01, and the bleeding volume of participants in the experimental group was remarkably lower in contrast to that of the control group. The MD was -65.48, 95% CI: (-77.84 to -53.13), Z=10.39, and P<0.01. The heterogeneity test of the chest tube removal time in 7 studies showed that Tau2 =0.29, Chi2 =28.27, df =6, I2=79%>50%, P<0.05, and the chest tube removal time of participants in the experimental group was substantially lower in contrast to that of the control group. The MD was -3.10, 95% CI: (-3.56 to -2.64), Z=13.30, P<0.01.DiscussionThis meta-analysis confirmed that VATS for spontaneous pneumothorax is better than other surgical methods.

Project description:BackgroundVideo-assisted thoracic surgery (VATS) generally involves endotracheal intubation under general anesthesia. However, inevitably, this may cause intubation-related complications and prolong the postoperative recovery process. Gradually, non-intubated video-assisted thoracic surgery (NIVATS) is increasingly being utilized. However, its safety and efficacy remain controversial.MethodsRandomized controlled trials (RCTs) published up to August 2020 were selected from the Cochrane Library, Web of Science, PubMed, Embase, and ClinicalTrials.gov databases and included in this study according to the inclusion criteria. Two reviewers screened these RCTs and independently extracted the relevant data. After assessing the risk of bias in these RCTs, a meta-analysis was performed using Review Manager 5.3. Pooled data were meta-analyzed using a random-effects model.ResultsMeta-analysis data demonstrated that the mean difference (MD) in the length of hospital stay between non-intubated patients and intubated patients was -1.41 days, with a 95% confidence interval (CI) of -2.47 to -0.34 (P=0.01). The visual analogue scale (VAS) score between the two groups showed a MD of -0.34 (95% CI: -0.58 to -0.10; P=0.006). Patients who underwent NIVATS presented with lower rates of overall complications [odds ratio (OR) 0.41; 95% CI: 0.25 to 0.67; P=0.0004], air leak (OR 0.45; 95% CI: 0.24 to 0.87; P=0.02), pharyngeal discomfort (OR 0.08; 95% CI: 0.04 to 0.17; P<0.00001), hoarseness (OR 0.06; 95% CI: 0.02 to 0.21; P<0.00001), and gastrointestinal reactions (OR 0.23; 95% CI: 0.10 to 0.53; P=0.0005) compared to intubated patients. The anesthesia satisfaction scores in the NIVATS group were significantly higher than those of the VATS group (MD 0.50; 95% CI: 0.12 to 0.88; P=0.009). However, there were no statistically significant differences in the length of operation time (MD 0.90 hours; 95% CI: -0.23 to 2.03; P=0.12) and surgical field satisfaction (1 point) (OR 0.73; 95% CI: 0.34 to 1.59; P=0.43) between the two groups.ConclusionsNIVATS is a safe and feasible form of intervention that can reduce the postoperative pain and complications of various systems and shorten hospital stay duration without prolonging the operation time.
