Abstract
BACKGROUND/PURPOSE Biomaterial implants are emerging as a treatment choice for pleurodesis; however, the optimal biomaterial and form for managing spontaneous pneumothorax, particularly post-video-assisted thoracic surgery, remain under investigation. This study evaluated the mechanical and biological properties of the poly-ε-caprolactone (PCL) membrane as a sclerosing agent for pleurodesis in Landrace pigs. METHODS Twenty-four Landrace pigs were split into two groups for mechanical abrasion and PCL membrane pleurodesis, with the latter group's PCL meshes inserted using video-assisted thoracic surgery. The mechanical and biological properties of the PCL membrane were assessed in pigs at three, six, and 12 months after the procedure. This assessment involved a range of techniques, such as the T-Peel test, macroscopic evaluation with a scoring scale, microscopic examination, and biomechanical and molecular weight analysis. RESULTS The PCL membrane group outperformed the traditional abrasion group, with stronger adhesions seen over longer implantation durations. This group also showed superior and more consistent results in both macroscopic and microscopic evaluations compared to the control group. The membrane-based method was easier and faster to perform than the control group's method, and importantly, no mortality occurred following membrane implantation. CONCLUSION This study is the pioneering effort to present long-term findings regarding the mechanical and biological properties of the PCL membrane in an in vivo animal model. The membrane demonstrated better adhesion ability than that of traditional abrasion and showed reassuring biocompatibility in both the pig model, suggesting its potential as treatment for patients with primary spontaneous pneumothorax. Further clinical studies are needed to support these observations.

Abstract
Background/purpose Biomaterial-based implants are gaining traction as an option for pleurodesis treatment, yet the search for the best biomaterial or the most suitable shape to handle spontaneous pneumothorax continues. This forward-looking research assessed the use of a poly-ε-caprolactone membrane for its safety when applied as a sclerosant in pleurodesis procedures in human patients. Methods From July 2017 to February 2018, we conducted a Phase I trial in which 10 patients with primary spontaneous pneumothorax were treated using video-assisted thoracoscopic surgery with a poly-ε-caprolactone membrane. These procedures encompassed bleb resection and mechanical pleurodesis through parietal pleura scrubbing. After resection, a 150 × 150 mm poly-ε-caprolactone membrane was applied to the apex. The primary outcome measures were the adverse events and laboratory outcomes. Results After surgery, we observed no cardiopulmonary-related adverse events or indications of systemic inflammation. Furthermore, no episodes of hypothermia or hyperthermia occurred. Chest radiographs showed no evident pneumonitis or effusion associated with tissue reactions. The average follow-up duration was 31.7 ± 17.7 months, during which two patients exhibited recurrence. Conclusion This study is the first to show the biocompatibility of poly-ε-caprolactone in humans, suggesting its potential as a treatment option for patients with primary spontaneous pneumothorax. Despite the relatively small number of patients, we maintain confidence in the reliability and safety profile of the PCL membrane, bolstered by its previously established efficacy in applications involving other organs. Phase II and phase III clinical studies are needed to support these observations.

Pain management after pneumothorax surgery: intercostal nerve block or thoracic epidural analgesia. INTERDISCIPLINARY CARDIOVASCULAR AND THORACIC SURGERY 2023; 37:ivad180. [PMID: 37941433 PMCID: PMC10645434 DOI: 10.1093/icvts/ivad180] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/25/2023] [Revised: 10/11/2023] [Accepted: 11/03/2023] [Indexed: 11/10/2023]
Abstract
OBJECTIVES In patients undergoing video-assisted thoracoscopic surgery for pneumothorax, the benefits and risks of single-shot intercostal nerve block as loco-regional analgesia are not well known. We retrospectively compared the effectiveness of intercostal nerve blocks as a viable alternative to thoracic epidural analgesia (TEA) regarding pain control and enhanced recovery. METHODS A retrospective multicentre analysis with single-centre propensity score matching was performed in patients undergoing video-assisted thoracoscopic surgery for pneumothorax receiving either TEA or intercostal nerve block. The primary outcome was a proportion of pain scores ≥4 (scale 0-10) until postoperative day (POD) 3. Secondary outcomes included variation in pain over time, additional opioid use, length of stay, mobility, complications and recurrence rate. RESULTS In 218 patients, TEA was compared to intercostal nerve block and showed no difference in the proportion of pain scores ≥4 {14.3% [interquartile range (IQR) 0.0-33.3] vs 11.1% (IQR 0.0-27.3) respectively, P = 0.24}, more frequently needed additional opioids on the day of surgery (18% vs 48%) and first POD (20% vs 42%), had a shorter length of stay (4.0 days [IQR 3.0-7.0] vs 3.0 days [IQR 2.8-4.0]) and were significantly more mobile until POD 3, while having similar recurrences. Intercostal nerve block had higher pain scores early in the course whereas TEA had higher late (rebound) pain scores. CONCLUSIONS In a multimodal analgesic setting with additional opioids, intercostal nerve block shows comparable moments of unacceptable pain from POD 0-3 compared to TEA and is linked to improved mobility. Results require randomized confirmation.

Abstract
INTRODUCTION Controversy exists in the optimal management of adolescent and young adult primary spontaneous pneumothorax. The American Pediatric Surgical Association (APSA) Outcomes and Evidence-Based Practice Committee performed a systematic review of the literature to develop evidence-based recommendations. METHODS Ovid MEDLINE, Elsevier Embase, EBSCOhost CINAHL, Elsevier Scopus, and Wiley Cochrane Central Register of Controlled Trials databases were queried for literature related to spontaneous pneumothorax between January 1, 1990, and December 31, 2020, addressing (1) initial management, (2) advanced imaging, (3) timing of surgery, (4) operative technique, (5) management of contralateral side, and (6) management of recurrence. The Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) guidelines were followed. RESULTS Seventy-nine manuscripts were included. Initial management of adolescent and young adult primary spontaneous pneumothorax should be guided by symptoms and can include observation, aspiration, or tube thoracostomy. There is no evidence of benefit for cross-sectional imaging. Patients with ongoing air leak may benefit from early operative intervention within 24-48 h. A video-assisted thoracoscopic surgery (VATS) approach with stapled blebectomy and pleural procedure should be considered. There is no evidence to support prophylactic management of the contralateral side. Recurrence after VATS can be treated with repeat VATS with intensification of pleural treatment. CONCLUSIONS The management of adolescent and young adult primary spontaneous pneumothorax is varied. Best practices exist to optimize some aspects of care. Further prospective studies are needed to better determine optimal timing of operative intervention, the most effective operation, and management of recurrence after observation, tube thoracostomy, or operative intervention. LEVEL OF EVIDENCE Level 4. TYPE OF STUDY Systematic Review of Level 1-4 studies.

Abstract
Background Spontaneous pneumothorax is a potentially fatal condition with a high risk of recurrence. The purpose of this study is to compare two different approaches to SP management. In the first group, patients underwent only chemical pleurodesis; in the second group, CT-scan, VATS, and then chemical pleurodesis was performed. Materials and Methods This study is a non-randomized clinical trial conducted on 65 patients admitted to Al-Zahra Hospital in Isfahan with a primary complaint of sudden dyspnea and a definitive diagnosis of spontaneous pneumothorax. Two studies compared the main outcomes of recurrence within six months and the time until recurrence. Results Age, sex, and BMI were matched between the two study groups. The side of the pneumothorax, smoking history, and pulmonary disease history did not differ significantly (P > 0.05). Pneumothorax recurrence did not differ significantly between the two groups (P: 0.477). Conclusion This study demonstrated no distinction between VATS and chemical pleurodesis when using only chemical pleurodesis. However, because numerous studies have suggested that one of these techniques may be beneficial for patients with SP, it is recommended to conduct additional randomized controlled trials (RCTs) with a more detailed plan and more comparable procedures, although it appears that meta-analysis design may be effective given the abundance of available RCT studies.

Abstract
INTRODUCTION Although three-port video-assisted thoracoscopic surgery (VATS) is the standard radical treatment for primary spontaneous pneumothorax (PSP), several issues need to be addressed as the postoperative recurrence rate remains relatively high. Although bullectomy is effective in preventing the postoperative recurrence of PSP, recurrent pneumothorax often occurs, requiring additional methods such as pleural covering with absorbable mesh sheets, surgical chemical pleurodesis, pleural abrasion, or pleurectomy. In addition, minimally invasive approaches that exceed three-port VATS are required according to the social demand. These approaches, such as uniportal VATS, reduced port surgery, and needlescopic surgery, have cosmetic merits, lower postoperative pain, and similar surgical results as three-port VATS. AREAS COVERED We focused on conventional and novel treatments for PSP in this article. EXPERT OPINION Effective methods that prevent postoperative recurrence and minimally invasive approaches will become popular in the near future.

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.

Abstract
Pneumothorax is a common medical condition encountered in a wide variety of clinical presentations, ranging from asymptomatic to life threatening. When symptomatic, it is important to remove air from the pleural space and provide re-expansion of the lung. Additionally, patients who experience a spontaneous pneumothorax are at high risk for recurrence, so treatment goals also include recurrence prevention. Several recent studies have evaluated less invasive management strategies for pneumothorax, including conservative or outpatient management. Future studies may help to identify who is greatest at risk for recurrence and direct earlier definitive management strategies, including thoracoscopic surgery, to those patients.

Abstract
OBJECTIVES Surgical management of spontaneous pneumothorax typically involves wedge resection and mechanical pleurodesis. It is unclear whether combining mechanical and chemical pleurodesis can further reduce the recurrence rate. We have performed a meta-analysis of studies comparing the combined approach with mechanical pleurodesis alone. METHODS A comprehensive search of the existing literature was performed using PubMed, EMBASE and Web of Science for all types of studies that compared combined pleurodesis to a single approach. We used the Cochrane Risk of Bias Tool and Strengthening The Reporting of OBservational Studies in Epidemiology (STROBE) to assess the quality of the studies. Relative risk of pneumothorax recurrence was calculated, and the differences between the studies were examined. The primary outcome was the recurrence of pneumothorax. RESULTS Of 2301 eligible studies, 5 studies were included. Five hundred sixty-one patients who received combined pleurodesis were compared to 286 patients who received mechanical pleurodesis only. Patients treated with combined intervention had a 63% lower risk of developing a recurrent pneumothorax compared to single intervention [relative risk 0.37, 95% confidence interval (CI) 0.18-0.76; P = 0.006]. There were no statistically significant differences in the length of stay (standardized mean difference -0.17, 95% CI -0.39 to 0.05, P = 0.138), the duration of postoperative air leak (standardized mean difference 0.17, 95% CI -1.14 to 1.47, P = 0.804) or the duration of postoperative chest tube drainage (standardized mean difference -0.07, 95% CI -0.27 to 0.12, P = 0.471). CONCLUSIONS This meta-analysis demonstrated that combined intervention with mechanical and chemical pleurodesis for spontaneous pneumothorax may be more effective in preventing recurrence than mechanical pleurodesis alone. These findings will provide some guidance to surgeons in the decision-making process.

Abstract
OBJECTIVE Various surgical procedures have been performed to decrease the recurrence of primary spontaneous pneumothorax after video-assisted thoracic surgery. This study aimed to examine the efficiency of pleural coverage for the prevention of postoperative recurrence in relatively young patients. METHODS Between January 2008 and December 2012, a total of 357 cases of 345 patients (age 15-29 years) with primary spontaneous pneumothorax who underwent bullectomy at 13 institutions were enrolled in this multi-institutional retrospective cohort study. A concurrent bilateral operation was counted as two cases. Polyglycolic acid sheets were used in 238 cases, and oxidized regenerated cellulose sheets were used in 37 cases to cover the visceral pleura, with no pleural coverage in 82 cases. The average observation period was 4.2 ± 2.0 years. RESULTS Postoperative recurrence was observed in 50 cases (14.0%) after video-assisted thoracic surgery. Twenty-six cases (10.9%) in the polyglycolic acid group, eight (21.6%) in the oxidized regenerated cellulose group, and sixteen (19.5%) in the non-coverage group experienced postoperative recurrence. Kaplan-Meier analysis revealed that the rate of freedom from postoperative recurrence in the polyglycolic acid group was significantly higher than that in the non-coverage group. Multivariate analysis showed that age ≥ 20 years and coverage with polyglycolic acid sheets were associated with reduced risk factors for postoperative recurrence. CONCLUSION Pleural coverage with a polyglycolic acid sheet is suggested to be effective in preventing postoperative recurrence of pneumothorax compared with non-coverage in relatively young patients.

Abstract
BACKGROUND Although thoracoscopic stapled bullectomy is a standard procedure for primary spontaneous pneumothorax (PSP), the postoperative recurrence rate is high. We investigated whether using a Vicryl (Ethicon, Somerville, NJ) mesh to cover the staple line after bullectomy reduces the postoperative recurrence rate. METHODS Our single-blind, parallel-group, prospective, randomized controlled trial at 2 medical centers in Taiwan studied patients with PSP who were aged 15 to 50 years and required thoracoscopic bullectomy. On the day of operation, patients were randomly assigned (1:1) to receive Vicryl mesh (mesh group) or not (control group) after thoracoscopic bullectomy with linear stapling and mechanical apical pleural abrasion. Randomization was achieved using computer-generated random numbers in sealed envelopes. Our primary end point was the pneumothorax recurrence rate within 1 year after the operation (clinicaltrials.gov number, NCT01848860.) RESULTS: Between June 2013 and March 2016, 102 patients were assigned to the mesh group and 102 to the control group. Within 1 year after operation, recurrent pneumothorax was diagnosed in 3 patients (2.9%) in the mesh group compared with 16 (15.7%) in the control group (P = .005). The short-term postoperative results and hospitalization duration were comparable between the groups. CONCLUSIONS For thoracoscopic bullectomy with linear stapling and mechanical apical pleural abrasion, the use of a Vicryl mesh to cover the staple line is effective for reducing the postoperative recurrence of pneumothorax. Vicryl mesh coverage can be considered an optimal adjunct to the standard surgical procedure for PSP.

Abstract
INTRODUCTION Primary spontaneous pneumothorax (PSP) and its high recurrence rate pose a therapeutic challenge to both patients and their managing surgeons. Mechanical or chemical pleurodesis can be used to prevent recurrence, but the optimal treatment often remains a matter of debate. This meta-analysis aims to compare the outcomes between mechanical and chemical pleurodesis following bullectomy for PSP. MATERIALS AND METHODS Studies published up to 2019 were searched from Medline, Embase, Google Scholar, and Cochrane databases. A meta-analysis of randomized controlled trials (RCTs) and observational cohort studies (OCSs) comparing outcomes between mechanical and chemical pleurodesis for PSP was performed. RESULTS Seven studies (one RCT and six OCSs) were included, comprising 1,032 cases of mechanical (799 abrasions, 202 pleurectomies, and 31 unspecified abrasions/pleurectomies/both), and 901 cases of chemical (643 talc, 69 minocycline, and 189 unspecified talc/kaolin) pleurodesis. The recurrence rate of pneumothorax after chemical pleurodesis (1.2%) was significantly lower than mechanical pleurodesis (4.0%) (pooled odds ratio [OR] = 3.00; 95% confidence interval [CI] = 1.59-5.67; p = 0.0007; I 2 = 19%). Hospital stay was also slightly shorter in the chemical pleurodesis group (pooled mean difference [MD] = 0.42 days; 95% CI = 0.12-0.72; p = 0.005; I 2 = 0%). There was no statistically significant difference in postoperative complications (pooled OR = 1.18; 95%CI = 0.40-3.48; p = 0.76; I 2 = 71%) and operative time (pooled MD = 3.50; 95%CI = -7.28 to 14.28; p = 0.52; I 2 = 99%) between these two groups. CONCLUSION Chemical pleurodesis is superior to mechanical pleurodesis following bullectomy for PSP in reducing hospital stay and recurrence rate. However, more RCTs with longer follow-up are necessary to demonstrate the benefit of chemical pleurodesis for PSP.

Abstract
Current deficiency in our understanding of acute-to-chronic pain transition remains a hurdle for developing effective treatments against chronic pain. Whereas neurocentric mechanisms alone are insufficient to provide satisfactory explanation for such transition, neuro-immune crosstalk has attracted attention in recent pain research. In contrast to brain microglia, spinal microglia are activated immediately in various pain states. The fast-responsive enrichment and activation of spinal microglia among different pain conditions have highlighted the crucial role of neuroinflammation caused by microglia-neuron crosstalk in pain initiation. Recent studies have revealed spinal microglia-neuron interactions are also involved in chronic pain maintenance, albeit, with different anatomic distribution, cellular and molecular mechanisms, and biologic functions. Delineating the exact temporal discrepancies of spinal microglia distribution and functions along acute-to-chronic pain transition may provide additional mechanistic insights for drug development to prevent deterioration of acute pain into the chronic state. This narrative review summerizes the longitudinal alterations of spinal microglia-neuron interactions in the initiation of pain hypersensitivity, acute-to-chronic pain progression, and chronic pain maintenance, followed by an overview of current clinical translation of preclinical studies on spinal microglia. This review highlights the crucial role of the interaction between spinal microglia and neighboring neurons in the initiation and maintenance of pain hypersensitivity, in relation to the release of cytokines, chemokines, and neuroactive substances, as well as the modulation of synaptic plasticity. Further exploration of the uncharted functions of spinal microglia-neuron crosstalk may lead to the design of novel drugs for preventing acute-to-chronic pain transition.

Abstract
Introduction: Pneumothorax is defined as the presence of air in the pleural space. Spontaneous pneumothorax, occurring without antecedent traumatic or iatrogenic cause, is classified as primary or secondary. There are substantial inconsistencies in international guidelines for the treatment of pneumothorax. Moreover, many geographical variations exist in daily clinical practice.Areas covered: In this article, we focus on novel treatment modalities for this significant health problem in young adults.Expert opinion: In part, these discrepancies have been caused by the lack of high-quality trials or evidence. Currently, the pathophysiological mechanisms underlying pneumothorax are better understood and have implications for clinical management. Studies have demonstrated that the judicious use of pleurodesis can decrease its rate of recurrence, both in surgical and nonsurgical patients.

Abstract
BACKGROUND Primary spontaneous pneumothorax (PSP) has a high rate of recurrence, and pleurodesis has been shown to decrease the rate of recurrence in adult PSP. For pediatric PSP patients, there are only a few case series available and evidence on the benefits of pleurodesis is insufficient. This study aimed to analyze the outcome of pleurodesis among pediatric PSP patients via a nationwide population-based cohort in Taiwan. METHODS The hospitalization data from the pediatric intensive care sampling file of the National Health Insurance Research Database from January 1 to December 31, 2010, were retrieved and analyzed. Children aged 0-18 years with a discharge diagnosis of PSP (ICD-9: 512, 512.0, and 512.8) were enrolled in the study. Demographic data, management strategies, and clinical outcomes were recorded and analyzed as well. RESULTS A total of 1005 hospitalization cases were identified and divided into the pleurodesis (409 hospitalizations) and nonpleurodesis (596 hospitalizations) groups. In the univariate analysis, thoracoscopic surgery for PSP decreased the incidence of recurrence (hazard ratio [HR], 0.46; 95% CI, 0.32-0.67) and the need for further surgical intervention (HR, 0.29; 95% CI, 0.18-0.47); however, conventional open surgery did not. A lesser incidence of PSP recurrence (HR, 0.53; 95% CI, 0.37-0.78) and fewer subsequent surgical interventions (HR, 0.32; 95% CI, 0.20-0.52) were found in the pleurodesis group in comparison with the nonpleurodesis group. A multivariate Cox regression analysis revealed that pleurodesis was the only significant factor capable of decreasing the incidence of PSP recurrence (HR, 0.57; 95% CI, 0.38-0.86) and the need for further surgical intervention (HR, 0.40; 95% CI, 0.23-0.69). CONCLUSION Pleurodesis reduces the rate of recurrence and the need for further surgical intervention in pediatric PSP. It may be considered as the method of choice for the management of PSP in children.

Abstract
OBJECTIVES This study aimed to identify the causes of recurrent pneumothorax and to evaluate the results of repeated video-assisted thoracic surgery (VATS) for recurrent pneumothorax after VATS wedge resection for primary spontaneous pneumothorax (PSP). METHODS A retrospective review was conducted on 188 patients with recurrent PSP, of a population of 1414 patients who underwent VATS wedge resection for PSP. Reoperations were performed when an air leak persisted longer than 3 days after closed thoracostomy, when a visible bulla of greater than 1 cm on high-resolution computed tomography (HRCT) was observed and when rerecurrence took place after other treatments. The HRCT findings before and after recurrence were compared to evaluate the type of the new bulla. Patients were divided into 2 groups according to the additional procedure performed during the first operation; in Group I, a coverage procedure was performed, and in Group II, mechanical pleurodesis was performed after VATS wedge resection. RESULTS During a median follow-up period of 27.7 months, 76 patients underwent repeated VATS for ipsilateral recurrent PSP after VATS. The indications for repeated VATS were the presence of a bulla on HRCT in 41 patients and a persistent air leak in 35 patients. Group I comprised 36 patients and Group II comprised 40 patients. The HRCT findings showed no bulla in 3 (4%) patients, were suspicious for a bulla in 11 (15%) patients, showed a bulla at the staple line in 26 (34%) patients and showed a new bulla in a location other than on the staple line in 36 (47%) patients. The frequency of new bullae was not different between the 2 groups, but Group I showed a lesser tendency for bullae to occur at the staple line than Group II. Dense fibrosis around the staple line was also found intraoperatively. CONCLUSIONS Repeated VATS was a feasible method to treat recurrent PSP after VATS for PSP.

Abstract
BACKGROUND/PURPOSE Pleurodesis with biomaterial implant is an emerging treatment method for pleural diseases. However, the ideal biomaterial or the optimal form for the common diseases is still under investigation. In our previous study, Poly-ε-caprolactone (PCL) membrane produces significant pleurodesis in New Zealand White rabbit animal models. METHODS We investigate the Poly-ε-caprolactone (PCL) gel pleurodesis by animal models using New Zealand White rabbits, which were sacrificed for examination after one month. Thirty-Six New Zealand White rabbits were randomized into three groups equally to undergo procedures. Gross pleurodesis scoring was evaluated. Additionally, inflammation and fibrosis scoring were done under microscopic evaluation, as well as Western blot analysis. RESULTS Gross evaluation of pleurodesis score revealed that lower concentrated PCL gel (10%) produced moderate pleural adhesion, while higher concentrated PCL gel (25%) showed significantly higher pleurodesis scores. (P < 0.05) Control group with thoracostomy alone produced almost no pleurodesis (P < 0.05). Western blot showed fibronectin expression was more evident in the 25% PCL gel than 10% one. CONCLUSION PCL gel induced significant degree of pleurodesis in the rabbits. The 25% PCL gel produces more intensive adhesion than 10% one. Fibronectin plays an important role in the process of pleurodesis. Further study is required for the clinical application of the promising biomaterial with gel form.

Abstract
OBJECTIVE The aim of this study was to compare coverage with oxidized regenerated cellulose mesh and that with polyglycolic acid sheet to decrease the incidence of postoperative recurrent pneumothorax. METHODS From August 2010 to August 2014, a total of 112 patients with primary spontaneous pneumothorax undergoing thoracoscopic bullectomy were enrolled. We compared the clinicopathological characteristics between recurrent and non-recurrent cases and examined their association with the material used for visceral pleural coverage: polyglycolic acid sheet versus oxidized regenerated cellulose mesh. RESULTS 57 patients underwent thoracoscopic bullectomy plus coverage using oxidized regenerated cellulose mesh and 55 underwent thoracoscopic bullectomy plus coverage using polyglycolic acid sheet. The recurrence rate among all patients was 13.3%. No severe postoperative complications were observed in either group. There were no significant differences in the perioperative outcomes. However, the postoperative recurrence rate was significantly higher in the oxidized regenerated cellulose mesh group than in the polyglycolic acid sheet group (22.8 vs 3.6%). CONCLUSIONS Our results suggest that coverage with oxidized regerated cellulose mesh was not superior to coverage with polyglycolic acid sheet for postoperative recurrent pneumothorax.

Abstract
BACKGROUND Primary spontaneous pneumothorax (PSP) remains a significant global health problem. Despite general agreement, an official algorithm for the management of PSP still does not exist. OBJECTIVES Evaluating the efficacy of all available treatments in PSP. METHODS A systematic search of 12 electronic databases was performed to identify all randomized controlled trials (RCTs) of any treatments in PSP. The primary endpoint was recurrence incidence; secondary were an immediate success, complication and hospitalization days. All available outcomes were included in frequentist network meta-analysis. RESULTS 4262 patients of 29 RCTs were included. In patients with first episode of PSP, video-assisted thoracoscopic surgery (VATS), tube drainage and aspiration had no significant difference regarding recurrence. Chemical pleurodesis significantly reduced the recurrent incidence of 46% compared with aspiration and 54% compared with tube drainage. VATS and aspiration significantly decreased hospitalization days compared with tube drainage. In patients with recurrent or persistent PSP, thoracotomy with mechanical pleurodesis has a higher rank than VATS with or without pleurodesis in preventing recurrence, with no significant difference. VATS alone significantly reduced complications compared with all others treatments, except thoracotomy with abrasion. CONCLUSIONS Aspiration and tube drainage have no significant difference in treating patients with first episode of PSP regarding recurrence. Aspiration reduced hospitalization days when compared with tube drainage. Thoracotomy with mechanical pleurodesis and VATS with or without pleurodesis are not significantly different in preventing recurrence in patients with recurrent or persistent PSP. VATS alone reduced complications compared with others treatments except for thoracotomy with abrasion.

BACKGROUND/PURPOSE Pleurodesis with biomaterial membrane is an emerging treatment method for pneumothorax. However, the ideal one for the common disease is still under debate. METHODS We investigate the Poly-ε-caprolactone (PCL) membrane pleurodesis by using New Zealand White rabbits, which was sacrificed for examination one month later. Moreover, inflammation and fibrosis scoring were done under microscopic evaluation, as well as Western blot analysis in vitro and in vivo. RESULTS Gross evaluation of pleurodesis score revealed that dense PCL membrane produced moderate pleural adhesion, while porous PCL membrane exhibited significantly higher pleurodesis scores. CONCLUSION PCL membrane induced significant degree of adhesion, both within the abdomen and chest of the rabbits. The porous PCL membrane produces more intensive adhesion than dense one. Fibronectin plays an important role in the process of pleurodesis. Further study is required for the clinical application of the promising material.

Is it possible to standardize the treatment of primary spontaneous pneumothorax? Part 2: surgical methods of treatment. POLISH JOURNAL OF THORACIC AND CARDIOVASCULAR SURGERY 2017; 13:328-333. [PMID: 28096830 PMCID: PMC5233763 DOI: 10.5114/kitp.2016.64875] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/21/2016] [Accepted: 11/16/2016] [Indexed: 11/17/2022]
Abstract
The present report provides a detailed description of the surgical methods for primary spontaneous pneumothorax (PSP) treatment, from open surgery (thoracotomy) to minimally invasive procedures (video-assisted thoracoscopic surgery - VATS). It describes the methods of preventing pneumothorax recurrence, including partial or complete resection of the parietal pleura and chemical pleurodesis with VATS. The pros and cons of each method are presented. The paper also discusses new techniques for diagnosing pneumothorax, such as fluorescein-enhanced autofluorescence thoracoscopy (FEAT) and infrared thoracoscopy. Finally, the authors propose their own algorithm for the treatment of PSP.

Optimal surgical technique in spontaneous pneumothorax: a systematic review and meta-analysis. J Surg Res 2016; 210:32-46. [PMID: 28457339 DOI: 10.1016/j.jss.2016.10.024] [Citation(s) in RCA: 34] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/18/2016] [Revised: 10/16/2016] [Accepted: 10/26/2016] [Indexed: 12/30/2022]
Abstract
BACKGROUND Numerous thoracoscopic techniques have been used in the management of primary spontaneous pneumothorax (PSP), including wedge resection, pleurectomy, pleural abrasion, chemical pleurodesis, and staple line covering. The purpose of this systematic review was to compare outcomes for the most commonly reported techniques. MATERIALS AND METHODS A systematic literature search looking at pneumothorax recurrence rate, length of stay, and chest tube duration after surgery was conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines using the PubMed database. RESULTS Fifty-one unique studies comprised of 6907 patients published between January 1988 and June 2015 were identified. Heterogeneity among effect sizes was significant for all outcomes. The lowest recurrence rates were observed in the wedge resection + chemical pleurodesis (1.7%; 95% confidence interval [CI], 1.0%-2.7%) and the wedge resection + pleural abrasion + chemical pleurodesis (2.8%; 95% CI, 1.7%-4.7%) groups. The shortest chest tube duration and length of stay were observed in the wedge resection + staple line covering ± other group (2.1 d; 95% CI, 1.4-2.9 and 3.3 d; 95% CI, 2.6-4.0, respectively). CONCLUSIONS The variability in reported outcomes and the lack of published multicenter randomized controlled trials highlights a need for more robust investigations into the optimal surgical technique in the management of PSP. Based on the limited quality studies available, this systematic review favors wedge resection + chemical pleurodesis and wedge resection + pleural abrasion + chemical pleurodesis in terms of recurrence rate after surgery for PSP.

Abstract
Objectives Spontaneous pneumothorax is a common pathology. International guidelines suggest pleurodesis for non-resolving air leak or recurrence prevention at second occurrence. This study comprehensively reviews the existing literature regarding chemical pleurodesis efficacy. Design We systematically reviewed the literature to identify relevant randomised controlled trials (RCTs), case–control studies and case series. We described the findings of these studies and tabulated relative recurrence rates or ORs (in studies with control groups). Meta-analysis was not performed due to substantial clinical heterogeneity. Results Of 560 abstracts identified by our search strategy, 50 were included in our systematic review following screening. Recurrence rates in patients with chest tube drainage only were between 26.1% and 50.1%. Thoracoscopic talc poudrage (four studies (n=249)) provided recurrence rates of between 2.5% and 10.2% with the only RCT suggesting an OR of 0.10 compared with drainage alone. In comparison, talc administration during video-assisted thoracic surgery (VATS) from eight studies (n=2324) recurrence was between 0.0% and 3.2%, but the RCT did not demonstrate a significant difference compared with bleb/bullectomy alone. Minocycline appears similarly effective post-VATS (recurrence rates 0.0–2.9%). Prolonged air leak and recurrence prevention using tetracycline via chest drain (n=726) is likely to provide recurrence rates between 13.0% and 33.3% and autologous blood patch pleurodesis (n=270) between 15.6% and 18.2%. Conclusions Chemical pleurodesis postsurgical treatment or via thoracoscopy appears to be most effective. Evidence for definitive success rates of each agent is limited by the small number of randomised trials or other comparative studies.

Abstract
Our study sought to determine whether the size of the residual apical pleural space in young patients with primary spontaneous pneumothorax (PSP) following video-assisted thoracoscopic surgery is associated with the risk of recurrence. We retrospectively reviewed patients (≤30 years' old) with primary spontaneous pneumothorax following thoracoscopic surgery (2002-2010) in a university-affiliated hospital. The size of residual apical pleural space was estimated by measuring the apex-to-cupola distance on a postoperative chest radiograph at 2 time windows: first between postoperative day (POD) 0 and 3, and second between POD 4 and 14. A total of 149 patients were enrolled with a median follow-up of 11.2 months (interquartile range, 0.95-29.5 months), of whom 141 (94.6%) were male with a mean age of 20 years. The postoperative recurrence rate was 11.4%. Comparing the characteristics between the patients with and without recurrent pneumothorax, the patients with recurrence were younger (18.2 + 2.4 vs 20.7 + 3.7 years, P = 0.008), with a lower rate of pleurodesis (35% vs1 69%, P = 0.037), longer apex-to-cupola distance at POD 0 to 3 (22.41 ± 19.56 vs 10.07 ± 10.83 mm, P < 0.001) and POD 4 to 14 (11.82 ± 9.75 vs 5.54 ± 8.38 mm, P = 0.005) than the patients without recurrence. In a multivariate logistic regression model for recurrent pneumothorax, age <18 years (P = 0.026, odds ratio [OR]: 4.694), apex-to-cupola distance at POD 0 to 3 >10 mm (P = 0.027, OR: 5.319), and no pleurodesis during VATS (P = 0.022, OR: 5.042) were independent risk factors for recurrent pneumothorax. The recurrence rate was not low (11.4%) in young patients with PSP following VATS. Residual apical pleural space with apex-to-cupola distance of 10 mm or greater at POD 0 to 3, younger age, and no pleurodesis would increase postoperative recurrence of primary spontaneous pneumothorax.

Abstract
Primary spontaneous pneumothorax (PSP) affects young healthy people with a significant recurrence rate. Recent advances in treatment have been variably implemented in clinical practice. This statement reviews the latest developments and concepts to improve clinical management and stimulate further research.The European Respiratory Society's Scientific Committee established a multidisciplinary team of pulmonologists and surgeons to produce a comprehensive review of available scientific evidence.Smoking remains the main risk factor of PSP. Routine smoking cessation is advised. More prospective data are required to better define the PSP population and incidence of recurrence. In first episodes of PSP, treatment approach is driven by symptoms rather than PSP size. The role of bullae rupture as the cause of air leakage remains unclear, implying that any treatment of PSP recurrence includes pleurodesis. Talc poudrage pleurodesis by thoracoscopy is safe, provided calibrated talc is available. Video-assisted thoracic surgery is preferred to thoracotomy as a surgical approach.In first episodes of PSP, aspiration is required only in symptomatic patients. After a persistent or recurrent PSP, definitive treatment including pleurodesis is undertaken. Future randomised controlled trials comparing different strategies are required.

The effect of pleural abrasion on the treatment of primary spontaneous pneumothorax: a systematic review of randomized controlled trials. PLoS One 2015; 10:e0127857. [PMID: 26042737 PMCID: PMC4456155 DOI: 10.1371/journal.pone.0127857] [Citation(s) in RCA: 43] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2014] [Accepted: 04/21/2015] [Indexed: 11/19/2022] Open
Abstract
BACKGROUND Pleural abrasion has been widely used to control the recurrence of primary spontaneous pneumothorax (PSP). However, controversy still exists regarding the advantages and disadvantages of pleural abrasion compared with other interventions in preventing the recurrence of PSP. METHODS The PubMed, Embase, and Cochrane Central Register of Controlled Trials databases were searched up to December 15, 2014 to identify randomized controlled trials (RCTs) that compared the effects of pleural abrasion with those of other interventions in the treatment of PSP. The study outcomes included the PSP recurrence rate and the occurrence rate of adverse effects. RESULTS Mechanical pleural abrasion and apical pleurectomy after thoracoscopic stapled bullectomy exhibited similarly persistent postoperative air leak occurrence rates (p = 0.978) and 1-year PSP recurrence rates (p = 0.821), whereas pleural abrasion led to reduced residual chest pain and discomfort (p = 0.001) and a smaller rate of hemothorax (p = 0.036) than did apical pleurectomy. However, the addition of minocycline pleurodesis to pleural abrasion did not reduce the pneumothorax recurrence rate compared with apical pleurectomy (3.8% for both procedures) but was associated with fewer complications. There was no statistical difference in the pneumothorax recurrence rate between mechanical pleural abrasion and chemical pleurodesis with minocycline on either an intention-to-treat basis (4 of 42 versus 0 of 42, p = 0.12; Fisher exact test) or after exclusions (2 of 40 versus 0 of 42, p = 0.24; Fisher exact test). Pleural abrasion plus minocycline pleurodesis also did not reduce the pneumothorax recurrence rate compared with pleural abrasion alone (p = 0.055). Moreover, pleural abrasion plus minocycline pleurodesis was associated with more intense acute chest pain. The postoperative overall recurrence rate in patients who underwent staple line coverage with absorbable cellulose mesh and fibrin glue was similar to that with mechanical abrasion after thoracoscopic bullectomy (13.8% vs. 14.2%, respectively; p = 0.555), but staple line coverage resulted in less postoperative residual pain than mechanical abrasion (0.4% vs.3.2%; p<0.0001). Pleural abrasion after thoracoscopic wedge resection did not decrease the recurrence of pneumothorax compared with wedge resection alone (p = 0.791), but the intraoperative bleeding and postoperative pleural drainage rates were higher when pleural abrasion was performed. CONCLUSIONS In addition to resulting in the same pneumothorax recurrence rate, thoracoscopic pleural abrasion with or without minocycline pleurodesis is safer than apical pleurectomy in the treatment of PSP. However, minocycline pleurodesis with or without pleural abrasion is not any more effective than pleural abrasion alone. Moreover, additional mechanical abrasion is not safer than additional staple line coverage with absorbable cellulose mesh and fibrin glue after thoracoscopic bullectomy because of increased postoperative pain. Additionally, pleural abrasion after thoracoscopic wedge resection should not be recommended for routine application due to the greater incidence of adverse effects than wedge resection alone. However, further large-scale, well-designed RCTs are needed to confirm the best procedure.

Abstract
PURPOSE OF REVIEW The role of chemical pleurodesis in the treatment of primary spontaneous pneumothorax remains unclear. According to current practice guidelines, chemical pleurodesis is reserved for patients who are unable or unwilling to have surgery. Some recent studies showed that intrapleural minocycline pleurodesis could decrease the rate of pneumothorax recurrence, when used either as the initial treatment for simple pneumothorax after successful aspiration and drainage or as an adjuvant treatment for complicated or recurrent pneumothorax following thoracoscopic surgery. The purpose of this review is to discuss the current available evidence on intrapleural minocycline pleurodesis for the treatment of primary spontaneous pneumothorax. RECENT FINDINGS In a recently published prospective, randomized controlled trial, additional minocycline pleurodesis following simple aspiration and drainage was a well tolerated and more effective initial treatment for a first episode of primary spontaneous pneumothorax than simple aspiration and drainage alone. Other prospective, randomized controlled trials showed that additional minocycline pleurodesis after thoracoscopic treatment was a well tolerated and convenient procedure which can reduce the rate of ipsilateral recurrence of primary spontaneous pneumothorax. SUMMARY Intrapleural minocycline pleurodesis can be considered an adjunct to standard treatment of primary spontaneous pneumothorax, after either simple aspiration and drainage or after thoracoscopic surgery.

Abstract
Video-assisted thoracic surgery (VATS) is a miniinvasive technique commonly applied worldwide. Indications for VATS are very broad and include the diagnosis of mediastinal, lung and pleural diseases, as well as large resection procedures such as pneumonectomy. The most frequent complication is prolonged postoperative air leak. The other significant complications are bleeding, infections, postoperative pain and recurrence at the port site. Different complications of VATS procedures can occur with variable frequency in various diseases. Despite the large number of their types, such complications are rare and can be avoided through the proper selection of patients and an appropriate surgical technique.

Abstract
OBJECTIVE The purpose of this consensus conference was to determine whether video-assisted thoracic surgery (VATS) improves clinical outcomes compared with conventional thoracotomy in patients undergoing surgery for pneumothorax, and to outline evidence-based recommendations for the use of VATS. METHODS Before the consensus conference, the best available evidence was reviewed, with systematic reviews, randomized trials, and nonrandomized trials all taken into consideration in descending order of validity and importance. At the consensus conference, evidence-based interpretative statements were created, and consensus processes were used to determine the ensuing recommendations. The Medical Information Network Distribution Service in Japan (Minds) system was used to label the levels of evidence for the references and the classes of recommendations. RESULTS AND RECOMMENDATIONS The consensus panel agreed upon the following statements and recommendations for patients with pneumothorax undergoing surgery: 1. VATS is broadly indicated as surgery for pneumothorax. 2. VATS is judged to be less invasive, as it results in minimal postoperative pain, the periods of chest tube placement and hospitalization are short, and it shows a trend toward early realization of social integration. 3. There is no difference in terms of safety and complications between VATS and open thoracotomy. 4. As it is anticipated that VATS will result in a higher recurrence rate than open thoracotomy, it may be desirable to add a supplemental procedure during surgery. In summary, VATS can be recommended as pneumothorax surgery (Recommendation grade: Level B).

Abstract
Pneumothorax is defined as the presence of air in the pleural cavity. Spontaneous pneumothorax, occurring without antecedent traumatic or iatrogenic cause, is sub-divided into primary and secondary. The severity of pneumothorax could be varied from asymptomatic to hemodynamically compromised. Optimal management of this benign disease has been a matter of debate. In addition to evacuating air from the pleural space by simple aspiration or chest tube drainage, the management of spontaneous pneumothorax also focused on ceasing air leakage and preventing recurrences by surgical intervention or chemical pleurodesis. Chemical pleurodesis is a procedure to achieve symphysis between the two layers of pleura by sclerosing agents. In the current practice guidelines, chemical pleurodesis is reserved for patients unable or unwilling to receive surgery. Recent researches have found that chemical pleurodesis is also safe and effective in preventing pneumothorax recurrence in patients with the first episode of spontaneous pneumothorax or after thoracoscopic surgery and treating persistent air leakage after thoracoscopic surgery. In this article we aimed at exploring the role of chemical pleurodesis for spontaneous pneumothorax, including ceasing air leakage and preventing recurrence. The indications, choice of sclerosants, safety, effects, and possible side effects or complications of chemical pleurodesis are also reviewed here.

Abstract
BACKGROUND Various procedures have been performed to decrease the incidence of recurrent postoperative pneumothorax after thoracoscopic bullectomy. The purpose of this study was to determine the efficacy of a polyglycolic acid (PGA) sheet and pleural abrasion for prevention of recurrent postoperative pneumothorax. METHODS From January 2009 to August 2011, 257 patients underwent thoracoscopic bullectomy for primary spontaneous pneumothorax. In group A, 128 patients underwent pleural abrasion. These patients were compared with 129 patients (group B) who underwent a procedure to cover stable lines with an absorbable PGA sheet in addition to pleural abrasion. RESULTS There was no difference in preoperative demographics, although the age of patients in group A was statistically higher than that of patients in group B (23.67 ± 6.54 versus 21.69 ± 5.65; p = 0.010). In group A, prolonged postoperative air leaks (≥ 3 days) occurred more frequently (7.8% versus 2.3%; p = 0.045). A Kaplan-Meier curve showed that recurrence-free rates were higher in group B (p = 0.047). CONCLUSIONS Coverage with PGA sheet and pleural abrasion after thoracoscopic bullectomy is effective for preventing prolonged postoperative air leaks and reducing postoperative recurrence rates.

BACKGROUND Simple aspiration and drainage is a standard initial treatment for primary spontaneous pneumothorax, but the rate of pneumothorax recurrence is substantial. We investigated whether additional minocycline pleurodesis after simple aspiration and drainage reduces the rate of recurrence. METHODS In our open-label, parallel-group, prospective, randomised, controlled trial at two hospitals in Taiwan, patients were aged 15-40 years and had a first episode of primary spontaneous pneumothorax with a rim of air greater than 2 cm on chest radiographs, complete lung expansion without air leakage after pigtail catheter drainage, adequate haematological function, and normal renal and hepatic function. After simple aspiration and drainage via a pigtail catheter, patients were randomly assigned (1:1) to receive 300 mg of minocycline pleurodesis or no further treatment (control group). Randomisation was by computer-generated random numbers in sealed envelopes. Our primary endpoint was rate of pneumothorax recurrence at 1 year. This trial is registered with ClinicalTrials.gov (NCT00418392). FINDINGS Between Dec 31, 2006, and June 30, 2012, 214 patients were randomly assigned-106 to the minocycline group and 108 to the control group (intention-to-treat population). Treatment was unsuccessful within 7 days of randomisation in 14 patients in the minocycline group and 20 patients in the control group. At 1 year, pneumothoraces had recurred in 31 of 106 (29·2%) patients in the minocycline group compared with 53 of 108 (49·1%) in the control group (p=0·003). We noted no procedure-related complications in either group. INTERPRETATION Simple aspiration and drainage followed by minocycline pleurodesis is a safe and more effective treatment for primary spontaneous pneumothorax than is simple aspiration and drainage only. Minocycline pleurodesis should be an adjunct to standard treatment for primary spontaneous pneumothorax. FUNDING Department of Health and National Science Council, Taiwan.

Abstract
OBJECTIVE To compare the efficacy and safety between apical pleurectomy and pleural abrasion with minocycline in primary spontaneous pneumothorax (PSP) with high recurrence risk. BACKGROUND The optimal thoracoscopic pleurodesis procedure for PSP with high recurrence risk remains controversial. METHODS Between January 2006 and May 2009, a total of 369 patients with spontaneous pneumothorax were treated by video-assisted thoracoscopic surgery. After stapled bullectomy, 160 patients with no identifiable bleb or multiple blebs (≥3) were randomly chosen to undergo apical pleurectomy (pleurectomy group, 80 patients) or pleural abrasion with minocycline (abrasion/minocycline group, 80 patients). RESULTS Patients in the pleurectomy group had a longer operation duration (mean, 81.4 minutes vs 55.8 minutes, P < 0.001), a greater amount of operation bleeding (mean, 29.4 mL vs 13.2 mL, P = 0.025), and a greater amount of postoperative chest drainage (mean, 287.4 mL vs 195.8 mL, P = 0.040). Patients in the abrasion/minocycline group had a higher intensity of chest pain and required more frequent meperidine injections. Hemothorax occurred in 3 pleurectomy patients (3.8%). The short-term results showed that the 2 groups had comparable durations of postoperative chest drainage, durations of postoperative hospital stay, and complication rates. After a mean follow-up of 26.1 months, recurrent ipsilateral pneumothorax occurred in 3 patients (3.8%) in the pleurectomy group and 3 patients (3.8%) in the abrasion/minocycline group. Postoperative long-term residual chest pain and pulmonary function were comparable in both groups. CONCLUSIONS : Pleural abrasion with minocycline pleurodesis is as effective as apical pleurectomy and either technique is appropriate for treating PSP patients with high recurrence risk. This trial was registered at http://www.clinicaltrials.gov (ID: NCT00270751).

Abstract
Primary spontaneous pneumothorax (PSP) commonly occurs in tall, thin, adolescent men. Though the pathogenesis of PSP has been gradually uncovered, there is still a lack of consensus in the diagnostic approach and treatment strategies for this disorder. Herein, the literature is reviewed concerning mechanisms and personal clinical experience with PSP. The chest computed tomography (CT) has been more commonly used than before to help understand the pathogenesis of PSP and plan further management strategies. The development of video-assisted thoracoscopic surgery (VATS) has changed the profiles of management strategies of PSP due to its minimal invasiveness and high effectiveness for patients with these diseases.

Abstract
Spontaneous pneumothorax (SP) is now commonly treated with thoracoscopic surgery, which is associated with less pain and a shorter hospital stay than thoracotomy; however, in its initial stages, thoracoscopic stapled bullectomy resulted in an unexpectedly high incidence of postoperative SP recurrence. Thus, new thoracoscopic procedures, designed to be performed in addition to stapled bullectomy, were developed, which resulted in a gradual decline in the postoperative recurrence rate. We review the recent literature on SP recurrence after thoracoscopic surgery with these other surgical procedures. Pleurectomy and pleural abrasion have been performed for a long time with low recurrence rates; however, they cause the lung to adhere to the parietal pleura, often resulting in complications such as postoperative bleeding. Other surgical procedures that may be recommended to minimize the risk of recurrence are reinforcement of the staple lines using fleece-coated glue or an absorbable sheet. These procedures are now considered to be the thoracoscopic treatment of choice for SP.

Abstract
BACKGROUND Simple aspiration is recommended as first-line treatment for all primary spontaneous pneumothoraces requiring intervention. However, the optimal salvage treatment remains unclear when simple aspiration is unsuccessful for controlling symptoms. In this study, the safety, efficacy, and estimated costs of video-assisted thoracoscopic surgery (VATS) and chest tube drainage (CTD) were compared. METHODS Between 2002 and 2007, 164 patients with a first episode of spontaneous pneumothorax were managed by simple aspiration. Among them, 52 patients underwent subsequent VATS (30 patients) or CTD (22 patients) due to unsuccessful aspiration. The demographic data and treatment outcomes of the two groups were collected through retrospective chart review. RESULTS Postoperative analgesics use did not differ between groups. Complications developed in 2 of the VATS group (6.7%) and 6 of the CTD group (27.3%), with mean hospital stays of 4.8 and 6.1 days, respectively (p = 0.034). Patients in the VATS group had lower rates of overall failure, although the rates of immediate failure were not significantly different. After a mean follow-up of 16 months, recurrent ipsilateral pneumothorax was noted in 1 VATS patient and 5 CTD individuals (p = 0.038). The estimated total costs per patient were $1,273 in the VATS group and $865 in the CTD group. CONCLUSIONS Although associated with higher costs, VATS rather than CTD is the preferred salvage treatment for unsuccessful aspiration of the first episode of primary spontaneous pneumothorax, because of shorter hospital stay and lower rates of overall failure and recurrence.

Abstract
BACKGROUND The ideal thoracoscopic pleurodesis method for preventing recurrence of spontaneous pneumothorax remains controversial. This study was conducted to compare the patterns, effects, and thoracic volume changes achieved using a variety of thoracoscopic procedures in rabbits. MATERIALS AND METHODS Thirty-six New Zealand White rabbits were randomly assigned to undergo the following thoracoscopic procedures in the left hemithorax: (a) parietal pleural abrasion; (b) minocycline instillation; (c) combination of abrasion and minocycline; or (d) examination alone. The rabbits were euthanatized 30 days after the operation to determine pleurodesis score, area of greatest adhesion, thoracic volume change, and histopathological findings. RESULTS Grossly, pleural abrasion produced moderate localized apical pleural symphysis with no obvious thoracic volume change. Minocycline instillation induced moderate generalized pleurodesis with a significant decrease in thoracic volume. The combination of abrasion and minocycline instillation produced the greatest generalized pleurodesis as well as a significant decrease in thoracic volume. On microscopic examination, the combination procedure produced the greatest inflammation and fibrosis of the visceral and parietal pleura. Increased intensity of pleurodesis score as well as pleural inflammation and fibrosis is associated with decreased thoracic volume. CONCLUSIONS Thoracoscopic pleurodesis achieved using pleural abrasion and minocycline instillation induced different patterns of pleurodesis, and a combination of each method generated a synergy and produced a better pleurodesis. However, as the generalization and intensity of the pleurodesis were inversely associated with thoracic volume, the optimal method should be determined on an individual basis according to the clinical situation.
