McNamara N, Cistulli D, Bannon P, Cao C. Predictors of surgical intervention in first episode primary spontaneous pneumothorax requiring chest drain insertion. ANZ J Surg 2024. [PMID: 39058249 DOI: 10.1111/ans.19170] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/14/2023] [Revised: 06/30/2024] [Accepted: 07/07/2024] [Indexed: 07/28/2024]
Abstract
BACKGROUND Primary spontaneous pneumothorax occurs in patients with no underlying lung disease and guidelines recommend chest tube drainage for the first episode, with surgical intervention reserved for recurrent episodes, persistent air leak or failure of lung re-expansion. Modern surgical management is associated with reduced length of hospital stay and superior freedom from recurrence compared with chest tube drainage alone. The objective of this study was to identify risk factors for failed chest tube drainage in patients who present with first episode primary spontaneous pneumothorax. METHODS A retrospective analysis of patients who presented to Royal Prince Alfred Hospital, Australia with first episode PSP and underwent chest tube insertion was performed. Patient demographics and size of pneumothorax were examined in relation to the primary outcome, a composite of failed chest tube drainage and recurrent ipsilateral pneumothorax. RESULTS Fifty-five patients underwent chest tube drainage for first episode primary spontaneous pneumothorax between 1st January 2017 and 31st December 2020. Complete lung collapse on admission chest x-ray was associated with an increased risk of the primary outcome (63% versus 19%, OR 7.3 [96% CI 2.0-27.4), P = 0.004). CONCLUSION This small retrospective study found that patients that undergo chest drain insertion for first episode primary spontaneous pneumothorax who present with complete lung collapse on admission are at high risk of requiring pleurodesis and therefore may benefit from early surgical referral.

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
Objectives Primary spontaneous pneumothorax (PSP) is a common disease in young and thin male. Operation has been regarded as definitive treatment for it. However, the operative methods for those patients are under dispute. This study aims to directly compare the outcomes of uniportal VATS vs. needlescopic VATS in the treatment of PSP, focusing on postoperative pain and safety outcomes. Methods From July 2013 to December 2017, the patients who underwent video-assisted thoracic surgery for pneumothorax in National Taiwan University Hospital were retrospectively collected. The preoperative condition, surgical results, and postoperative outcomes was analyzed. Results There were 60 patients undergoing needlescopic VATS and 91 undergoing uniportal VATS during the study period. There was no significant difference between the patients who underwent needlescopic VATS and those who underwent uniportal VATS in their demographic and clinical characteristics. The post-operative pain score was significantly lower in the uniportal VATS group compared to the needlescopic VATS group at day 1 (2.65 ± 1.59 vs. 1.74 ± 1.35, p = 0.001). Conclusion Uniportal VATS offers an effective, safe alternative for PSP treatment, with benefits including reduced post-operative pain. Our findings support the use of uniportal VATS, supplemented by a wound protector, as a viable option for PSP patients.

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.

Abstract
Background This study aims to evaluate current practices in the management of primary spontaneous pneumothorax among Turkish pediatric surgeons. Methods Between October 2021 and November 2021, an online survey comprising 19 questions was delivered to all members of the Turkish Association of Pediatric Surgeons (TAPS). A total of 74 respondents (42 males, 32 females; mean age: 42.3±7.9 years; range, 29 to 61 years) were included. Results The response rate was 17.1% among all society members. The rate of utilization of computed tomography in the initial admission was 27.4%, and the rate of use in cases requiring surgical treatment was 78.4%. A total of 81% of surgeons reported that the size of the pneumothorax influenced management. For the first episode of primary spontaneous pneumothorax, 75.7% of surgeons opted for chest tube drainage, 14.9% for only oxygen administration, 4.1% for needle aspiration, and none of the surgeons preferred video-assisted thoracoscopic surgery. For patients with a persistent air leak after chest tube placement, there was a wide variation in the duration of observation before performing surgery. Video-assisted thoracoscopic surgery was the most preferred surgical intervention (75.3%) and the most preferred surgical method was stapled bullectomy (43.8%). Conclusion There are practice variations in the management of pediatric primary spontaneous pneumothorax among the society members. However, the majority of members seem to agree on the use of computed tomography, initial treatment, and surgical interventions.

Abstract
Bullous lung diseases may cause primary spontaneous pneumothorax (PSP) in children. The microRNAs (miRNAs) are non-coding RNAs that participate in regulation of inflammation and cancer. We hypothesized that children with bullous lung disease and PSP may have altered miRNA expressions in their exhaled breath condensates (EBCs). Therefore, a prospective study was performed to evaluate the miRNA-24 and 21 expression, and the matrix metalloproteinase-7 (MMP-7) levels in EBC of children with PSP. Children with PSP were evaluated for age, gender, clinical features and results of surgical treatment. EBC samples (500-1000 ml) were collected to evaluate the miRNA-21, 24 expressions, and MMP-7, and tissue-inhibitor-MMP-1 (TIMP-1) levels. miRNA expressions and MMP levels of patients were compared with healthy controls (control group (CG),n= 12). Subjects (n= 16) with a mean age of 15 years (10-19 years), and a male-to-female ratio of 14:2 were enrolled in this study. The most common presenting symptom was sudden chest pain (n= 14). In 62.5% of the cases an underlying bullous lung disease were detected. During an average of 16.6 months (1-60 months) follow up period, four subjects relapsed. The mean MMP-7 (1.74-1.57 ng ml-1), and TIMP-1 (1.92-1.84 ng ml-1) levels were similar between both groups (p> 0.05). miRNA-24 expression was significantly decreased in the PSP group, when compared to the CG (0.16-1 2-ΔΔCT,p< 0.05). In addition, the miRNA-21 expression was not different between the two groups (p> 0.05). In conclusion, the miRNA-24 levels were significantly decreased in children with PSP. Taken together, children with PSP, especially those with bullous disease, should be closely monitored in the long-term period.

Abstract
BACKGROUND We aimed at comparing in a multicenter propensity-matched analysis, results of nonintubated versus intubated video-assisted thoracic surgery (VATS) bullectomy/blebectomy for primary spontaneous pneumothorax (PSP). METHODS Eleven Institutions participated in the study. A total of 208 patients underwent VATS bullectomy by intubated (IVATS) (N = 138) or nonintubated (NIVATS) (N = 70) anesthesia during 60 months. After propensity matching, 70 pairs of patients were compared. Anesthesia in NIVATS included intercostal (N = 61), paravertebral (N = 5) or thoracic epidural (N = 4) block and sedation with (N = 24) or without (N = 46) laryngeal mask under spontaneous ventilation. In the IVATS group, all patients underwent double-lumen-intubation and mechanical ventilation. Primary outcomes were morbidity and recurrence rates. RESULTS There was no difference in age (26.7 ± 8 vs 27.4 ± 9 years), body mass index (19.7 ± 2.6 vs 20.6 ± 2.5), and American Society of Anesthesiology score (2 vs 2). Main results show no difference both in morbidity (11.4% vs 12.8%; p = 0.79) and recurrence free rates (92.3% vs 91.4%; p = 0.49) between NIVATS and IVATS, respectively, whereas a difference favoring the NIVATS group was found in anesthesia time (p < 0.0001) and operative time (p < 0.0001), drainage time (p = 0.001), and hospital stay (p < 0.0001). There was no conversion to thoracotomy and no hospital mortality. One patient in the NIVATS group needed reoperation due to chest wall bleeding. CONCLUSION Results of this multicenter propensity-matched study have shown no intergroup difference in morbidity and recurrence rates whereas shorter operation room time and hospital stay favored the NIVATS group, suggesting a potential increase in the role of NIVATS in surgical management of PSP. Further prospective studies are warranted.

Abstract
BACKGROUND In this study, we aimed to analyze the effects of admission time to the hospital and different variables on the treatment efficiency and to evaluate the recurrence during the clinical management process in patients with the diagnosis of primary spontaneous pneumothorax. METHODS A total of 149 patients with primary spontaneous pneumothorax (131 males, 18 females; mean age: 24.8±6.8 years; range, 17 to 35 years) treated in our clinic between January 2015 and December 2019 were retrospectively analyzed. Time from symptom onset to hospital admission (admission time) was classified as three periods: <24 h, between 24 and 72 h, and >72 h. Data including admission time, demographic and clinical characteristics, smoking history, body mass index, the use of pleurectomy or pleural abrasion during surgery were collected from the charts of the patients. RESULTS Admission time had no statistically significant effect on the length of hospital stay, recurrence, and the need for surgery. Male sex, smoking history, and lower body mass index had no significant effect on the recurrence. Recurrence and length of hospital stay did not significantly differ between the patients in whom pleurectomy or pleural abrasion added to the procedure during the operation. CONCLUSION A longer interval between symptom onset and hospital admission and lower body mass index have no adverse effect on treatment outcomes and the recurrence in patients with primary spontaneous pneumothorax. Despite the fact that surgical treatment significantly decreases the recurrence rate, pleurectomy and pleural abrasion techniques have no significant difference on the clinical influence and recurrence of these patients.

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
BACKGROUND In many cases of secondary spontaneous pneumothorax (SSP), surgery is not feasible. Furthermore, in cases with a collapsed lung or numerous air leaks, pleurodesis is ineffective, and treatment options are severely limited. For these cases, bronchial occlusion might be the only effective treatment, despite the low success rate. If, however, bronchial occlusion can expand the lung and reduce air leakage, it can positively amplify later effects on pleurodesis, resulting in a powerful treatment. We reviewed the clinical data of patients who underwent bronchial occlusion with endobronchial Watanabe spigot (BO-EWS) and pleurodesis to investigate the usefulness of bronchial occlusion therapy in inoperable SSP patients. MATERIALS AND METHODS This single-center, retrospective study reviewed 36 cases of inoperable SSP patients who underwent pleurodesis after BO-EWS from April 2007 to October 2018. Twenty cases were allocated to the air leak analysis group, and 16 cases were included in the pneumothorax volume analysis group. The Robert David Cerfolio classification and the Collins method were used to evaluate air leak and pneumothorax volume, respectively. RESULTS Pneumothorax volumes decreased significantly after BO-EWS from 29.1%±17.3% to 12.1%±8.8%, while the air leak score decreased from 2.9±1.4 to 1.2±1.0. The success rate for chest tube removals in cases that underwent pleurodesis after BO-EWS was 85.0% (17/20). CONCLUSIONS This study demonstrated the synergistic effectiveness of BO-EWS and the usefulness of pleurodesis treatment in inoperable SSP patients with lung collapse or numerous air leaks. We believe that this treatment will benefit patients with inoperable SSP which, until now, has had few treatment options.

METHODS Cohort study using the California Public Discharge Data file (1995-2010). We identified patients with first-time spontaneous pneumothorax. The primary outcome was recurrent pneumothorax. Associations with clinical, patient, and hospital characteristics were assessed using Cox regression analysis. RESULTS Among 14,609 patients with a first-time episode of spontaneous pneumothorax, 26.2% developed a recurrence. Risk factors included age <35 (Hazard Ratio [HR] 1.24 95%-Confidence Interval [CI] 1.14-1.36), Asian race (HR 1.24, CI 1.13-1.37), and tube thoracostomy (HR 1.2, CI 1.15-1.31). Mechancial pleurodesis (HR 0.37 CI 0.31-0.45) was superior to chemical pleurodesis (HR 0.71 CI 0.58-0.86) in reducing recurrence risk. CONCLUSIONS The risk of recurrent pneumothorax is greatest in patients age <35, Asians, and those requiring a tube thoracostomy. The risks of operative intervention should be balanced against patient risk for recurrence.

Recommendation for management of patients with their first episode of primary spontaneous pneumothorax, using video-assisted thoracoscopic surgery or conservative treatment. Sci Rep 2021; 11:10874. [PMID: 34035334 PMCID: PMC8149688 DOI: 10.1038/s41598-021-90113-w] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/15/2020] [Accepted: 05/04/2021] [Indexed: 01/11/2023] Open
Abstract
International guidelines do not recommend surgery for the first episode of primary spontaneous pneumothorax (PSP), except in cases of persistent air leak, hemopneumothorax, bilateral pneumothorax, or occupations at risk. However, these recommendations have been challenged because of a significant reduction in the recurrence rate in emerging studies. We evaluated the rationale of recommendations by systematically reviewing RCTs and observational studies by using the Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) system. We searched articles in PubMed, EMBASE, and Cochrane databases up to August 15, 2020. The primary outcomes were the recurrence rate and complication rate. The secondary outcomes were hospital stay and drainage duration. Nine eligible studies with 1121 patients were retrieved and analyzed. The recurrence rate was lower in the VATS than in conservative treatment with moderate evidence (OR 0.13, 95% CI 0.09 to 0.19, P < 0.001, I2 = 0%). We did not find significant differences in complication rate (Peto OR 1.17, 95% CI 0.33 to 4.12, P = 0.80), hospital stay duration (MD − 0.48 days, 95% CI − 2.84 to 1.87, P = 0.69, very low evidence), and in drainage duration (MD − 3.99 days, 95% CI − 9.06 to 1.08, P = 0.12, very low evidence) between the two groups. Our results would suggest VATS treatment as a weak recommendation for patients with the first episode of PSP, based on our systematic review of the current evidence by using the GRADE system, indicating that different treatments will be appropriate for different patients and that patients’ values and preferences should be incorporated through shared decision making.

Vicryl Mesh Coverage Reduced Recurrence After Bullectomy for Primary Spontaneous Pneumothorax. Ann Thorac Surg 2021; 112:1609-1615. [PMID: 33279544 DOI: 10.1016/j.athoracsur.2020.11.012] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/05/2020] [Revised: 11/03/2020] [Accepted: 11/16/2020] [Indexed: 01/19/2023]
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
Background: Although pleurodesis is usually used to reduce the recurrence rate for primary spontaneous pneumothorax (PSP) in surgery, existing techniques cannot meet the higher requirements of little surgical injury and less relapse. Hence, we developed a new pleurodesis technique and named multipoint pleura cautery. Aim: In this study, we aimed to investigate the effectiveness and outcomes of the uniportal video-assisted thoracoscopic surgery C-shaped pleura cautery in the surgical treatment of PSP. To the best of our knowledge, this is a new surgical technique for pleurodesis and must be of concern. Patients and Methods: The medical records of 20 patients undergoing surgery for C-shaped pleura cautery between 2015 and 2017 were reviewed. The patients were evaluated with regard to age, gender, body mass index, smoking habit, operation time, duration of hospitalization, post-operative pain and follow-up. Results: We have performed a bullectomy combined C-shaped pleura cautery for 20 patients with PSP from January 2016 to December 2017. None of the patients suffered post-operative bleeding and haematothorax complications, and one was ipsilateral relapsed 5 months after surgery. The lung computed tomography showed that recurrence of pneumothorax was due to air leakage in the right lower lung, and there was no air leakage at the site where pleurodesis had been performed. Conclusions: Although this technique requires further investigation, it may be a useful method of pleurodesis.

Abstract
OBJECTIVE This study aimed to evaluate the recurrence rate after primary and secondary conservative treatments and to clarify the validity of current primary spontaneous pneumothorax management by comparing secondary conservative treatment and surgical outcomes. METHODS Data from 166 patients with primary spontaneous pneumothorax treated at a single site between September 2015 and March 2019 were retrospectively evaluated. Patient characteristics of those who received primary conservative therapy (n = 166) and secondary conservative therapy (n = 28) were summarized. The outcomes from patients who experienced recurrence (n = 64) were compared based on those who underwent surgery (n = 24) and those who underwent secondary conservative therapy (n = 28). RESULTS The post-treatment day 60 recurrence rate was 27.1 and 49.5% cases in the primary and secondary treatment groups, respectively, which was significantly higher after secondary treatment than after primary treatment with conservative therapy (p = 0.032). The post-treatment one-year recurrence rate was 13.5 and 57.9% in patients who underwent surgery and secondary conservative treatment, respectively; secondary conservative treatment resulted in a significantly higher recurrence rate than surgery (p < 0.001). CONCLUSIONS There is evidence for guidelines that recommend surgery for recurrent primary spontaneous pneumothorax after primary conservative therapy based on its lower and more delayed post-treatment recurrence rate than secondary treatment with conservative therapy.

Abstract
BACKGROUND With the advancement of cardiorespiratory interventions, the survival rate among patients with Duchenne muscular dystrophy (DMD) has increased. Subsequently, pneumothorax has become a significant problem in patients with prolonged ventilatory support. RESEARCH QUESTION What are the frequency, recurrence rate, risk factors, and prognosis of pneumothorax in patients with DMD requiring noninvasive ventilation (NIV)? Also, are there known risk factors of pneumothorax on chest CT scans? STUDY DESIGN AND METHODS This retrospective longitudinal cohort study included 176 patients treated between 2006 and 2019. We collected information regarding location, severity, treatment methods, recurrence frequency, abnormal findings on CT scanning, and date of death. We compared the pneumothorax and nonpneumothorax groups. We calculated the estimated survival probabilities from the age at NIV application according to pneumothorax occurrence. RESULTS Sixteen of the 176 patients (9.0%) experienced pneumothorax (median age at diagnosis, 24.6 years; range, 20.7-33.7 years). Among the 16 patients, 15 demonstrated pneumothorax after NIV application (median time between diagnosis and initial NIV application, 5.6 years; range, 3 days-9.6 years). Sixteen patients experienced 31 episodes of pneumothoraces (range, one-five episodes); among them, seven episodes (22.6%) were asymptomatic. Known risk factors not clearly visible by radiography scans were found in chest CT scan in 11 patients (68.8%). Seven of 16 patients (43.8%) eventually sustained severe lung damage with pulmonary fibrosis. No significant between-group differences were found in body weight, BMI, and age at NIV application; however, the pneumothorax group showed a significantly higher mortality rate after NIV application. INTERPRETATION On pneumothorax occurrence in patients with DMD, recurrences and severe lung damage are common; moreover, these patients show higher mortality rates than patients without pneumothorax. Chest CT scans should be performed to identify risk factors, and treatment should be initiated accordingly. In addition, physicians should consider chest CT scanning in the case of suspected pneumothorax, even if no radiographic abnormality is found.

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
Nonintubated video-assisted thoracoscopic surgery for the treatment of primary and secondary pneumothorax was first reported in 1997 by Nezu. However, studies on this technique are few. Research in the past 20 years has focused on the perioperative outcomes, including the surgical duration, length of hospital stay, and postoperative morbidity and respiratory complication rates, which appear to be better than those of surgery under intubated general anesthesia. This study provides information pertaining to the physiologic, surgical, and anesthetic aspects and describes the potential benefits of nonintubated thoracoscopic surgery for the management of primary and secondary spontaneous pneumothorax.

Abstract
Background Video-assisted thoracoscopic surgery (VATS) is considered an acceptable treatment for recurrent primary spontaneous pneumothorax (PSP). However, recent reports have described a high postoperative recurrence rate in young patients with PSP. We hypothesized that ineffective VATS may have been performed for these patients (aged <25 years). We evaluated the factors preventing postoperative recurrence in young PSP patients in order to identify patients with effective surgery. Methods Between April 2009 and December 2018, we retrospectively evaluated 92 patients aged <25 years who underwent first VATS bullectomy for PSP. Factors such as gender, smoking habit, history of contralateral PSP, family history, body mass index (BMI), and contralateral bulla neogenesis on high-resolution computed tomography were evaluated. Results The mean BMI was 18.8±1.8. Contralateral bulla neogenesis was present in 31 patients (33.7%). The median period of observation for postoperative recurrence was 401.5 days. Thirty cases (32.6%) developed postoperative recurrence. Univariate and multivariable analyses showed that a BMI ≥18.0 and no contralateral bulla neogenesis were significant factors preventing postoperative recurrence (P=0.018, hazard ratio: 0.41 and P=0.0046, hazard ratio: 0.25, respectively). Conclusions Although the patients aged <25 years have a high rate of postoperative recurrence, the patients with BMI ≥18.0 and no contralateral bulla neogenesis have a significantly lower rate of postoperative recurrence rate.

Abstract
BACKGROUND Whether conservative management is an acceptable alternative to interventional management for uncomplicated, moderate-to-large primary spontaneous pneumothorax is unknown. METHODS In this open-label, multicenter, noninferiority trial, we recruited patients 14 to 50 years of age with a first-known, unilateral, moderate-to-large primary spontaneous pneumothorax. Patients were randomly assigned to immediate interventional management of the pneumothorax (intervention group) or a conservative observational approach (conservative-management group) and were followed for 12 months. The primary outcome was lung reexpansion within 8 weeks. RESULTS A total of 316 patients underwent randomization (154 patients to the intervention group and 162 to the conservative-management group). In the conservative-management group, 25 patients (15.4%) underwent interventions to manage the pneumothorax, for reasons prespecified in the protocol, and 137 (84.6%) did not undergo interventions. In a complete-case analysis in which data were not available for 23 patients in the intervention group and 37 in the conservative-management group, reexpansion within 8 weeks occurred in 129 of 131 patients (98.5%) with interventional management and in 118 of 125 (94.4%) with conservative management (risk difference, -4.1 percentage points; 95% confidence interval [CI], -8.6 to 0.5; P = 0.02 for noninferiority); the lower boundary of the 95% confidence interval was within the prespecified noninferiority margin of -9 percentage points. In a sensitivity analysis in which all missing data after 56 days were imputed as treatment failure (with reexpansion in 129 of 138 patients [93.5%] in the intervention group and in 118 of 143 [82.5%] in the conservative-management group), the risk difference of -11.0 percentage points (95% CI, -18.4 to -3.5) was outside the prespecified noninferiority margin. Conservative management resulted in a lower risk of serious adverse events or pneumothorax recurrence than interventional management. CONCLUSIONS Although the primary outcome was not statistically robust to conservative assumptions about missing data, the trial provides modest evidence that conservative management of primary spontaneous pneumothorax was noninferior to interventional management, with a lower risk of serious adverse events.

Abstract
OBJECTIVES We retrospectively assessed the initial clinical impact of the locally administered bacteriostatic antibiotic, powder minocycline, during surgery for active infective endocarditis (AIE). METHODS Among 38 surgical AIE patients, 36 patients who underwent surgical intervention for AIE using local administration of powder minocycline between January 2008 and August 2017 in our institute were enrolled. During surgery, the local administration and dispersion of powder minocycline at not only the valvular annulus and perivalvular cavity, but also the prosthetic cuff and ring were performed following the complete resection and aggressive debridement of infectious tissues. Early clinical outcomes, including survival, postoperative co-morbidities, and freedom from re-intervention or significant paravalvular leakage (PVL), were assessed. RESULTS Early mortality within 30 days was 5.6% and hospital death was 13.9%. There was no reoperation within 30 days and only one patient (3.8%) developed recurrent infection, which improved with additional antibiotic treatments. More than moderate PVL within 30 days was detected in one patient only (3.8%). Over a median follow-up period of 38.3 ± 35.5 months, a Kaplan-Meier analysis revealed that 1- and 5-year survival rates were 75.7 and 66.8%, respectively, and freedom from reoperation was 100% at 5 years. Freedom from significant PVL at 5 years was 91.0%. CONCLUSIONS The local administration of powder minocycline may be a simple and effective manipulation during surgical intervention for AIE without extensive reconstruction; however, the surgical management of AIE remains challenging.

Abstract
Background: Pleurodesis is often used to prevent the re-accumulation of a malignant
pleural effusion (MPE). Intrapleural urokinase (IPUK) therapy facilitates
lung re-expansion for patients with loculated MPE or a trapped lung that
allows subsequent pleurodesis. MPE management has been traditionally
regarded as a symptomatic treatment. We tried to evaluate their impact on
patient survival. Methods: There were 314 consecutive patients with symptomatic MPE that underwent
minocycline pleurodesis with (n = 109) and without
(n = 205) the antecedent IPUK therapy between September
2005 and August 2015, who were recruited for the pleurodesis outcome and
survival analysis. Results: The rate of successful pleurodesis was similar between the simple pleurodesis
group and the IPUK therapy group followed by the pleurodesis group (69.0%
versus 70.5%; p = 0.804). The patients
who succeeded pleurodesis had a longer survival rate than those who failed
in either the simple pleurodesis group (median, 414 versus
100 days; p < 0.001) or the IPUK therapy followed by
pleurodesis group (259 versus 102 days; p
< 0.001). The survival differences remained when the lung and breast
cancer patients were studied separately. Conclusion: Successful pleurodesis translated into a better survival rate that promotes
performing pleurodesis on lung re-expansion. The apparent shorter survival
of the patients with loculated MPE or trapped lung, and those that did not
respond to the IPUK therapy, lowered the probability of the survival benefit
through the simple physical barrier by the fibrin formation to prevent the
tumor spreading. The successfully induced inflammatory response by
minocycline is supposed to prohibit the tumor invasion and metastasis.
Further studies are warranted to clarify the mechanism and provide
opportunities to develop novel therapeutic strategies.

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
The pathophysiology and management of primary spontaneous pneumothorax (PSP) are a subject of debate. Despite advances in the understanding of its etiopathogenesis and improvements in its management, implementation in clinical practice is suboptimal. In this manuscript, we review the recent literature with a focus on PSP pathophysiology and management. Blebs and emphysema-like changes (ELC) are thought to contribute to the pathophysiology of PSP but cannot explain all cases. Recent studies emphasize the role of a diffuse porosity of the visceral pleura. Others found a relationship between smoking, occurrence of a PSP and bronchiolitis, which could be the initial pathological process leading to ELC development. Recent or ongoing studies challenge the need to systematically remove air from the pleural cavity of stable patients, introducing conservative management as a valuable therapeutic option. Evidence is growing in favour of needle aspiration instead of chest tube insertion, when air evacuation is needed. In addition, ambulatory management is considered as a successful approach in meta-analyses and is under exploration in a large randomized study. Because of a high recurrence rate of PSP, the benefit of performing a pleurodesis at first occurrence is under evaluation with interesting but not generalizable results. Better identification of 'at risk patients' is needed to improve the investigation strategy. Finally, recent publications confirm the efficacy, security and cost-effectiveness of graded talc poudrage pleurodesis to prevent PSP recurrence. In conclusion, PSP pathophysiology and management are still under investigation. The results of recently published and ongoing studies should be more widely implemented in clinical practice.

Abstract
IMPORTANCE Spontaneous pneumothorax is a common disease known to have an unusual epidemiological profile, but there are limited contemporary population-based data. OBJECTIVE To estimate the incidence of hospital admissions for spontaneous pneumothorax, its recurrence and trends over time using large, longstanding hospitalization data sets in England. DESIGN, SETTING, AND PARTICIPANTS A population-based epidemiological study was conducted using an English national data set and an English regional data set, each spanning 1968 to 2016, and including 170 929 hospital admission records of patients 15 years and older. Final date of the study period was December 31, 2016. EXPOSURES Calendar year (for incidence) and readmission to hospital for spontaneous pneumothorax (for recurrence). MAIN OUTCOMES AND MEASURES Primary outcomes were rates of hospital admissions for spontaneous pneumothorax and recurrence, defined as a subsequent hospital readmission with spontaneous pneumothorax. Record-linkage was used to identify multiple admissions per person and comorbidity. Risk factors for recurrence over 5 years of follow-up were assessed using cumulative time-to-failure analysis and Cox proportional hazards regression. RESULTS From 1968 to 2016, there were 170 929 hospital admissions for spontaneous pneumothorax (median age, 44 years [IQR, 26-88]; 73.0% male). In 2016, there were 14.1 spontaneous pneumothorax admissions per 100 000 population 15 years and older (95% CI, 13.7-14.4), a significant increase compared with earlier years, up from 9.1 (95% CI, 8.1-10.1) in 1968. The population-based rate per 100 000 population 15 years and older was higher for males (20.8 [95% CI, 20.2-21.4]) than for females (7.6 [95% CI, 7.2-7.9]). Of patients with spontaneous pneumothorax, 60.8% (95% CI, 59.5%-62.0%) had chronic lung disease. Record-linkage analysis demonstrated that the overall increase in admissions over time could be due in part to an increase in repeat admissions, but there were also significant increases in the annual rate of first-known spontaneous pneumothorax admissions in some population subgroups, for example in women 65 years and older (annual percentage change from 1968 to 2016, 4.08 [95% CI, 3.33-4.82], P < .001). The probability of recurrence within 5 years was similar by sex (25.5% [95% CI, 25.1%-25.9%] for males vs 26.0% [95% CI, 25.3%-26.7%] for females), but there was variation by age group and presence of chronic lung disease. For example, the probability of readmission within 5 years among males aged 15 to 34 years with chronic lung disease was 39.2% (95% CI, 37.7%-40.7%) compared with 19.6% (95% CI, 18.2%-21.1%) in men 65 years and older without chronic lung disease. CONCLUSIONS AND RELEVANCE This study provides contemporary information regarding the trends in incidence and recurrence of inpatient-treated spontaneous pneumothorax.

Abstract
Primary spontaneous pneumothorax (PSP) recurrence rates vary widely in the published literature, with limited data describing the factors that influence recurrence. The aims of this systematic review were to determine an estimation of PSP recurrence rates and describe risk factors for recurrence.A systematic review was conducted of all studies reporting PSP recurrence. Electronic searches were performed to identify English language publications of randomised trials and observational studies. The population was adults with PSP, who underwent conservative management, pleural aspiration or chest drainage. The outcome of interest was recurrence. Articles were screened and data extracted from eligible studies by two reviewers.Of 3607 identified studies, 29 were eligible for inclusion, comprising 13 548 patients. Pooled 1-year and overall recurrence rates were 29.0% (95% CI 20.9–37.0%) and 32.1% (95% CI 27.0–37.2%), respectively. Female sex was associated with increased recurrence (OR 3.03, 95% CI 1.24–7.41), while smoking cessation was associated with a four-fold decrease in risk (OR 0.26, 95% CI 0.10–0.63). I2 for random effects meta-analysis was 94% (p<0.0001), reflecting high heterogeneity between studies.This systematic review demonstrates a 32% PSP recurrence rate, with greatest risk in the first year. Female sex was associated with higher risk, suggesting possible sex-specific pathophysiology.

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.

Abstract
BACKGROUND AND OBJECTIVE Talc pleurodesis is commonly performed to manage refractory pleural effusion or pneumothorax. It is considered as a safe procedure as long as a limited amount of large particle size talc is used. However, acute respiratory distress syndrome (ARDS) is a rare but serious complication after talc pleurodesis. We sought to determine the risk factors for the development of ARDS after pleurodesis using a limited amount of large particle size talc. METHODS We retrospectively reviewed patients who underwent pleurodesis with talc or OK-432 at the University of Tokyo Hospital. RESULTS Twenty-seven and 35 patients underwent chemical pleurodesis using large particle size talc (4 g or less) or OK-432, respectively. Four of 27 (15%) patients developed ARDS after talc pleurodesis. Patients who developed ARDS were significantly older than those who did not (median 80 vs 66 years, P = 0.02) and had a higher prevalence of underlying interstitial abnormalities on chest computed tomography (CT; 2/4 vs 1/23, P < 0.05). No patient developed ARDS after pleurodesis with OK-432. This is the first case series of ARDS after pleurodesis using a limited amount of large particle size talc. CONCLUSION Older age and underlying interstitial abnormalities on chest CT seem to be risk factors for developing ARDS after talc pleurodesis.

Abstract
BACKGROUND Whether body mass index (BMI) is a significant risk factor for recurrence of primary spontaneous pneumothorax (PSP) remains controversial. The purpose of this study was to examine whether BMI and other factors are linked to risk of PSP recurrence. METHODS A consecutive cohort of 273 patients was retrospectively evaluated. Patients were divided into those who experienced recurrence (n = 81) and those who did not (n = 192), as well as into those who had low BMI (n = 75) and those who had normal or elevated BMI (n = 198). The two pairs of groups were compared in terms of baseline data, and Cox proportional hazards modeling was used to identify predictors of PSP recurrence. RESULTS Rates of recurrence among all 273 patients were 20.9% at 1 year, 23.8% at 2 years, and 28.7% at 5 years. Univariate analysis identified the following significant predictors of PSP recurrence: height, weight, BMI, size of pneumothorax, and treatment modality. Multivariate analyses identified several risk factors for PSP recurrence: low BMI, pneumothorax size ≥50%, and non-surgical treatment. Kaplan-Meier survival analysis indicated that patients with low BMI showed significantly lower recurrence-free survival than patients with normal or elevated BMI (P < 0.001). CONCLUSIONS Low BMI, pneumothorax size ≥50%, and non-surgical treatment were risk factors for PSP recurrence in our cohort. Low BMI may be a clinically useful predictor of PSP recurrence.

Abstract
OBJECTIVES There is an on-going discussion regarding the recurrence rate after surgery for primary spontaneous pneumothorax by video assisted thoracic surgery (VATS) or by thoracotomy access. This study aimed to describe the recurrence rate, and to identify a possible learning curve, following surgery for primary spontaneous pneumothorax by VATS. DESIGN All patients who underwent surgery for primary spontaneous pneumothorax by VATS at Karolinska University Hospital 2004-2013 were reviewed. Preoperative and operative characteristics were obtained from medical records. Patients were followed-up through telephone interviews or questionnaires and by review of medical records. The primary outcome of interest was time to recurrence of pneumothorax requiring intervention. Outcomes were compared between patients operated during 2004-June 2010 and July 2010-2013. RESULTS 219 patients who underwent 234 consecutive procedures were included. The mean follow-up times were 6.3 and 2.9 years in the early and late period, respectively. The postoperative recurrence rate in the early period was 16% (11%-25%), 18% (12%-27%), and 18% (12%-27%), at 1, 3 and 5 years, compared to 1.7% (0.4%-6.8%), 7.6% (3.7%-15%), and 9.8% (4.8%-19%) at 1, 3 and 5 years, in the late period (p = 0.016). CONCLUSIONS We found that the recurrence rate after thoracoscopic surgery for primary spontaneous pneumothorax decreased significantly during the study period. Our results strongly suggest that thoracoscopic surgery for pneumothorax involve a substantial learning curve.

Abstract
Guidelines on spontaneous pneumothorax are contradictory as to intervention between needle aspiration (NA) and chest tube drainage (CTD). Studies show poor adherence to guidelines.Three Norwegian hospitals included patients with primary (PSP) and secondary (SSP) spontaneous pneumothorax. Patients underwent NA or CTD as the primary intervention. The main outcome was duration of hospital stay. Secondary outcomes were immediate- and 1-week success rates and complications.127 patients were included, including 48 patients with SSP. 65 patients underwent NA, 63 patients CTD. Median (interquartile range) hospital stay was significantly shorter for NA: 2.4 days (1.2–4.7 days), compared with CTD: 4.6 days (2.3–7.8 days) (p<0.001). The corresponding figures for the SSP subgroup were 2.54 days (1.17–7.79 days) compared with 5.53 days (3.65–9.21 days) (p=0.049) for NA and CTD, respectively. Immediate success rates were 69% for NA compared with 32% for CTD (p<0.001). The positive effect of NA remained significant in sub-analyses for SSP. There was no significant difference in 1-week success rates. Complications occurred only during the CTD-treatment.Our study shows shorter hospital stay and higher immediate success rates for NA compared with CTD. Subgroup analyses also show clear benefits for NA for both PSP and SSP.

Abstract
Small-bore thoracic catheter drainage is recommended for a first large or symptomatic episode of primary spontaneous pneumothorax (PSP). However, one-third of these patients require a second procedure because of treatment failure. We investigated the factors associated with unsuccessful pigtail catheter drainage in the management of PSP. In this retrospective study, using a prospectively collected database, we enrolled 253 consecutive patients with PSP who underwent pigtail catheter drainage as initial treatment, from December 2006 to June 2011. The chest radiograph was reviewed in each case and pneumothorax size was estimated according to Light’s index. Other demographic factors and laboratory data were collected via chart review. Pigtail catheter drainage was successful in 71.9% (182/253) of cases. Treatment failure rates were 42.9%, 25.9%, and 15.5% in patients with pneumothorax sizes of >62.6%, 38–62.6%, and <38%, respectively (tertiles). An alternative cut-off point of 92.5% lung collapse was defined using a classification and regression tree method. According to the multivariate analysis, a large-size pneumothorax (p = 0.009) was the only significant predictor of initial pigtail catheter drainage treatment failure in patients with PSP. Early surgical treatment could be considered for those patients with a large-sized pneumothorax.

Optimal surgical technique in spontaneous pneumothorax: a systematic review and meta-analysis. J Surg Res 2016; 210:32-46.

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
BACKGROUND Video-assisted thoracoscopic surgery (VATS) is an increasingly common treatment for recurrent or persistent primary spontaneous pneumothorax (PSP). Surgery usually involves diffuse treatment of the pleura and possible targeted therapy to areas of bullous disease. The purpose of this large cohort study was to examine incidence of recurrence after VATS and identify predictors of outcome. METHODS Patients undergoing VATS for PSP at a single centre between 2000 and 2012 were prospectively enrolled. All patients underwent talc poudrage. Targeted surgical techniques were used based on presence of air leak and Vanderschueren's stage. Patients had clinical and radiological follow-up for at least 2 years (median 8.5 years). RESULTS 1415 patients with PSP underwent VATS with talc poudrage. The most frequent indications were recurrent pneumothorax (92.2%) and persistent air leak (6.5%). The complication rate was 2.0% of which 1.7% was prolonged air leak. There was no mortality. Median length of stay was 5 days. Recurrent pneumothorax occurred in 26 patients (1.9%). At the time of surgery, 592 patients smoked (43%) and they had a significantly higher incidence of recurrence (24/575, 4.2%) than non-smokers (2/805, 0.2%), p<0.001. The incidence of recurrence in those undergoing bullae suturing (3.8%, n=260) was significant higher than those undergoing poudrage alone (0.3%, p=0.036). CONCLUSION The marked difference in recurrence between smokers and non-smokers suggests this as an important predictor of outcome. This study demonstrates a low incidence of recurrence and complications for patients with PSP undergoing VATS with talc poudrage. Talc poudrage requires prospective comparison with pleurectomy and mechanical abrasion.

Abstract
A prolonged air leak caused by pulmonary tuberculosis is difficult to treat, and little is known about optimal treatment strategies. We herein report the case of a 60-year-old man who demonstrated tuberculous empyema with a fistula. An air leak from a tuberculous cavity in his left upper lobe persisted for approximately 4 months; surgical repair could not be performed due to a poor physical status and undernourishment. However, the air leak was successfully treated with endobronchial occlusion using two silicone spigots in left B3b and B4, without any adverse effects or aggravation of the infection.

Abstract
There are substantial differences in international guidelines for the management of pneumothorax and much geographical variation in clinical practice. These discrepancies have, in part, been driven by a paucity of high-quality evidence. Advances in diagnostic techniques have increasingly allowed the identification of lung abnormalities in patients previously labelled as having primary spontaneous pneumothorax, a group in whom recommended management differs from those with clinically apparent lung disease. Pathophysiological mechanisms underlying pneumothorax are now better understood and this may have implications for clinical management. Risk stratification of patients at baseline could help to identify subgroups at higher risk of recurrent pneumothorax who would benefit from early intervention to prevent recurrence. Further research into the roles of conservative management, Heimlich valves, digital air-leak monitoring, and pleurodesis at first presentation might lead to an increase in their use in the future.

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.

Abstract
BACKGROUND We determined the chest height in a cohort of patients with primary spontaneous pneumothorax (PSP) who had received chest radiographic examinations prior to the attack. The aim of this study was to determine when their chest height began to change and how this was related to the PSP. METHODS From June 2009 to February 2012, the chest posteroanterior radiographs of 156 patients with PSP (Group 1) were reviewed. Among another 3134 patients with PSP, we identified 52 patients who had a chest posteroanterior radiograph prior to the attack (Group 2). We also recruited 196 controls for comparison (Group 3). The chest height and chest width at different levels were measured and analyzed. RESULTS Before 14 years of age, the chest height of patients in Group 2 was no different from that of patients in Group 3. By the age of 14 years, however, the chest height and upper chest width of patients with PSP was significantly higher than that of the normal controls. The difference from normal chest height did not increase at adulthood. CONCLUSION The rapid increase in chest height and upper chest width is a unique finding in patients with PSP. It might be attributable to the occurrence of PSP. This finding may also help to identify patients who are at risk of PSP.
