The risk of secondary spontaneous pneumothorax in patients with chronic obstructive pulmonary disease in Taiwan. Respir Med 2024; 228:107672. [PMID: 38763446 DOI: 10.1016/j.rmed.2024.107672] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/02/2024] [Revised: 05/12/2024] [Accepted: 05/16/2024] [Indexed: 05/21/2024]
Abstract
INTRODUCTION Secondary spontaneous pneumothorax (SSP) is often linked to chronic obstructive pulmonary disease (COPD). The frequency of SSP occurrence in COPD patients varies among different research findings. SSPs are more commonly found in the elderly population diagnosed with COPD. Previous studies have reported a pneumothorax rate of 26 per 100,000 COPD patients. There is, however, a notable lack of detailed epidemiological information regarding SSP in Asia. Our study focused on determining the occurrence rate of SSP among COPD patients in Taiwan using an extensive national database. Additionally, this study aimed to identify comorbidities associated with SSP in this patient group. METHODS In this study, we used the Longitudinal Health Insurance Database, which contains records of 2 million people who were randomly chosen from among the beneficiaries of the Taiwan National Health Insurance program. The dataset includes information from 2005 to the end of 2017. Our focus was on individuals diagnosed with COPD, identified through ICD-9-CM codes in at least one hospital admission or two outpatient services, with the COPD diagnosis date as the index date. The exclusion criteria included individuals younger than 40 years, those with incomplete records, or those with a previous diagnosis of pneumothorax before the index date. We conducted a matched comparison by pairing COPD patients with control subjects of similar age, sex, and comorbidities using propensity score matching. The follow-up for all participants started from their index date and continued until they developed pneumothorax, reached the study's end, withdrew from the insurance program, or passed away. The primary objective was to evaluate and compare the incidence of pneumothorax between COPD patients and matched controls. RESULTS We enrolled 65,063 patients who were diagnosed with COPD. Their mean age (±SD) was 66.28 (±12.99) years, and approximately 60 % were male. During the follow-up period, pneumothorax occurred in 607 patients, equivalent to 9.3 % of the cohort. The incidence rate of SSP in COPD patients was 12.10 per 10,000 person-years, whereas it was 6.68 per 10,000 person-years in those without COPD. Furthermore, COPD patients with comorbidities such as atrial fibrillation, congestive heart failure, coronary artery disease, diabetes mellitus, hypertension, and cancer exhibited an increased incidence of SSP compared to COPD patients without such comorbidities. This was observed after conducting a multivariable Cox regression analysis adjusted for age, sex, and other comorbidities. CONCLUSION Our study revealed an elevated risk of SSP in patients with COPD. It has also been suggested that COPD patients with comorbidities, such as atrial fibrillation, congestive heart failure, coronary artery disease, diabetes mellitus, hypertension, and cancer, have an increased risk of developing SSP.

Current situation of management of spontaneous pneumothorax in Japan: A cross-sectional cohort study. Respir Investig 2024; 62:328-333. [PMID: 38401246 DOI: 10.1016/j.resinv.2024.02.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/27/2023] [Revised: 01/03/2024] [Accepted: 02/11/2024] [Indexed: 02/26/2024]
Abstract
BACKGROUND Limited epidemiological information is available on spontaneous pneumothorax. To address this gap, the Japan Society for Pneumothorax and Cystic Lung Disease (JSPCLD) conducted a nationwide retrospective survey to investigate the current epidemiology of spontaneous pneumothorax in Japan. METHODS In this study, we conducted a retrospective cross-sectional cohort study to demonstrate the clinical features of spontaneous pneumothorax in one year from April 2019 to March 2020, compare patient characteristics and treatment outcomes between primary (PSP) and secondary spontaneous pneumothorax (SSP), and investigate the risk factors associated with in-hospital mortality among patients with SSP. RESULTS A total of 1784 patients from 28 institutions were enrolled in the study, with PSP observed in 956 cases (53.6%) and SSP in 817 cases (45.8%). The age distribution showed a biphasic peak caused by the different peaks between PSP and SSP. In-hospital mortality occurred in 42 cases (2.4%) among all patients, with 0 cases (0%) in PSP and 42 cases (5.1%) in SSP. Multivariable analyses revealed that interstitial pneumonia as an underlying disease (odds ratio: 2.4700, 95% confidence interval: 1.1100 to 5.4800, p = 0.0269), performance status≧3 (odds ratio: 7.3900, 95% confidence interval: 3.1900 to 17.2000, p < 0.0001), and lower value of serum albumin on admission (odds ratio: 0.4060, 95% confidence interval: 0.2140 to 0.7690, p = 0.0057) were significantly associated with in-hospital mortality among patients with SSP. CONCLUSIONS SSP patients with poor baseline conditions are at a higher risk for in-hospital mortality. It is crucial to provide close and meticulous management for SSP patients with compromised conditions.

Comparison of Observation Alone Versus Interventional Procedures in Hemodynamically Stable Patients With Pneumothorax: A Systematic Review and Meta-Analysis. Cureus 2024; 16:e58385. [PMID: 38756278 PMCID: PMC11097702 DOI: 10.7759/cureus.58385] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 04/16/2024] [Indexed: 05/18/2024] Open
Abstract
Several studies indicate that observation alone is sufficient for the management of stable pneumothorax. To compare clinical efficacy, tolerability, and safety outcomes for treating hemodynamically stable adult patients with pneumothorax, the present review compared observation alone versus interventional procedures. We searched PubMed and Google Scholar from inception until June 24, 2020, for randomized controlled trials (RCTs) comparing observational therapy with conventional therapy for the treatment of adult pneumothorax. The pediatric age group and patients with tension pneumothorax were not included. Four hundred and forty-six patients were enrolled in three RCTs. The failure rate (relative risk (RR) 4.30; 95% CI = 0.23-81.82, p = 0.33) and mortality (RR 1.01; 95% CI = 0.31-3.33, p = 0.98) of observation were comparable to those of the chest tube. Chest tube and observation both carried comparable risks of complications, including tension pneumothorax and empyema (RR 3.15; 95% CI = 0.67-1) and (RR 1.55; 95% CI = 0.21-11.56, p = 0.67), respectively. Between chest tubes and observation, there was no statistically significant difference in the duration of hospital stay. We conclude that observation is as safe and effective at treating adult patients with stable pneumothorax as a chest tube.

Beyond diagnosis: a narrative review of the evolving therapeutic role of medical thoracoscopy in the management of pleural diseases. J Thorac Dis 2024; 16:2177-2195. [PMID: 38617786 PMCID: PMC11009601 DOI: 10.21037/jtd-23-1745] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/13/2023] [Accepted: 02/02/2024] [Indexed: 04/16/2024]
Abstract
Background and Objective Medical thoracoscopy (MT) is an endoscopic technique performed by interventional pulmonologists with a favorable safety profile and few contraindications, providing diagnostic and therapeutic intervention in a single sitting. This narrative review was designed to summarize the therapeutic role of MT based on the latest results from the available literature. Methods Pertinent literature published in English, relative to human studies, between 2010-2022 was searched in Medline/PubMed and Cochrane databases. Publications regarded as relevant were considered for inclusion in this review; additional references were added based on the authors' knowledge and judgment. The review considered population studies, meta-analyses, case series, and case reports. Key Content and Findings MT has mostly been described and is currently used globally in the diagnostic approach to exudative pleural effusion of undetermined origin. Carefully evaluating the literature, it is clear that there is initial evidence to support the use of MT in the therapeutic approach of malignant pleural effusion, pneumothorax, empyema, and less frequently hemothorax and foreign body retrieval. Conclusions MT is an effective procedure for treating the clinical entities presented in this document; it must be carried out in selected patients, managed in centers with high procedural expertise. Further evidence is needed to assess the optimal indications and appropriate patients' profiles for therapeutic MT. The endpoints of length of hospital stay, surgical referral, complications and mortality will have to be considered in future studies to validate it as a therapeutic intervention to be applied globally.

Spontaneous Pneumothorax in a Healthy Young Woman: Discussion About Treatment Options. Cureus 2024; 16:e55633. [PMID: 38586686 PMCID: PMC10996433 DOI: 10.7759/cureus.55633] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 03/06/2024] [Indexed: 04/09/2024] Open
Abstract
A spontaneous pneumothorax, a potentially life-threatening condition, is a disease process in which air enters the space between the visceral and parietal pleural of the lung, thus increasing the pressures in that space. It can be diagnosed by both physical exam and radiographic testing. In this case, we present a 21-year-old, otherwise healthy woman who presented with sudden, sharp shoulder pain and chest tightness and was diagnosed with her first, spontaneous pneumothorax. We further discuss the diagnosis and treatment options for a first-time spontaneous pneumothorax.

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
Introduction Spontaneous pneumothorax (SP) affects both young, otherwise healthy individuals and older persons with known underlying pulmonary disease. Initial management possibilities are evolving and range from observation to chest tube insertion. SP guidelines suggest an individualized approach based on multiple factors such as symptoms, size of pneumothorax, comorbidity and patient preference. Aim With this Danish national survey we aimed to map organization of care including involved specialties, treatment choice, training, and follow-up plans to identify aspects, and optimization of spontaneous pneumothorax management. Method A survey developed by the national interest group for pleural medicine was sent to all departments of emergency medicine, thoracic surgery, respiratory medicine, and to relevant departments of abdominal or orthopaedic surgery. Results The response rate was 75 % (47 of 65). Overall, 21% of responding departments had no guideline for SP management, which was provided by multiple specialties with marked heterogeneity in choice of treatment including tube size, management during admission, and referral procedure to follow-up. Few departments required procedure training, and nearly all of the responders called for improvements in management of pneumothorax. Conclusion This survey suggests that SP management and care is delivered heterogeneously across Danish hospitals with marked difference between respiratory physicians, emergency physicians, general surgeons and thoracic surgeons. It is therefore likely that management is sub-optimal. There is a need for a common Danish SP guideline to ensure optimal treatment across involved specialties.

Abstract
BACKGROUND Risk factors for hypoxemia in school-age children undergoing one-lung ventilation remain poorly understood. The hypothesis was that certain modifiable and nonmodifiable factors may be associated with increased risk of hypoxemia in school-age children undergoing one-lung ventilation and thoracic surgery. METHODS The Multicenter Perioperative Outcomes Group database was queried for children 4 to 17 yr of age undergoing one-lung ventilation. Patients undergoing vascular or cardiac procedures were excluded. The original cohort was divided into two cohorts: 4 to 9 and 10 to 17 yr of age inclusive. All records were reviewed electronically for the primary outcome of hypoxemia during one-lung ventilation, which was defined as an oxygen saturation measured by pulse oximetry (Spo2) less than 90% for 3 min or longer continuously, while severe hypoxemia was defined as Spo2 less than 90% for 5 min or longer. Potential modifiable and nonmodifiable risk factors associated with these outcomes were evaluated using separate multivariable least absolute shrinkage and selection operator regression analyses for each cohort. The covariates evaluated included age, extremes of weight, American Society of Anesthesiologists Physical Status of III or higher, duration of one-lung ventilation, preoperative Spo2 less than 98%, approach to one-lung ventilation, right operative side, video-assisted thoracoscopic surgery, lower tidal volume ventilation (defined as tidal volume of 6 ml/kg or less and positive end-expiratory pressure of 4 cm H2O or greater for more than 80% of the duration of one-lung ventilation), and procedure type. RESULTS The prevalence of hypoxemia in the 4- to 9-yr-old cohort and the 10- to 17-yr-old cohort was 24 of 228 (10.5% [95% CI, 6.5 to 14.5%]) and 76 of 1,012 (7.5% [95% CI, 5.9 to 9.1%]), respectively. The prevalence of severe hypoxemia in both cohorts was 14 of 228 (6.1% [95% CI, 3.0 to 9.3%]) and 47 of 1,012 (4.6% [95% CI, 3.3 to 5.8%]). Initial Spo2 less than 98% was associated with hypoxemia in the 4- to 9-yr-old cohort (odds ratio, 4.20 [95% CI, 1.61 to 6.29]). Initial Spo2 less than 98% (odds ratio, 2.76 [95% CI, 1.69 to 4.48]), extremes of weight (odds ratio, 2.18 [95% CI, 1.29 to 3.61]), and right-sided cases (odds ratio, 2.33 [95% CI, 1.41 to 3.92]) were associated with an increased risk of hypoxemia in the older cohort. Increasing age (1-yr increment; odds ratio, 0.88 [95% CI, 0.80 to 0.97]) was associated with a decreased risk of hypoxemia. CONCLUSIONS An initial room air oxygen saturation of less than 98% was associated with an increased risk of hypoxemia in all children 4 to 17 yr of age. Extremes of weight, right-sided cases, and decreasing age were associated with an increased risk of hypoxemia in children 10 to 17 yr of age. EDITOR’S PERSPECTIVE

Abstract
Background Several risk factors for postoperative recurrence of spontaneous pneumothorax have been reported, but the identified risk factors differed among studies. Methods A total of 183 primary spontaneous pneumothorax patients were enrolled in this retrospective study, and the risk factors for postoperative recurrence were evaluated. Results Among the patients, more than 80% with ipsilateral postoperative recurrence (IPR) relapsed within 3 years and more than 80% with contralateral postoperative recurrence relapsed within 4 years. Compared with patients without IPR, patients with IPR had significantly more cases with history of pneumothorax (P<0.10), more cases without preoperative drainage (P=0.02), more cases with intraoperative adhesion (P<0.01), greater upward lung volume (P=0.04), more numbers of automatic sutures (P=0.04), and more cases with contralateral recurrence (P<0.01). Furthermore, compared with patients without adhesion, patients with adhesion had significantly older age (P<0.01), and more cases with adhesion on CT images (P<0.01). Patients with adhesion also had significantly greater upward lung volume (P<0.01), more cases that received covering with polyglycolic acid (PGA) sheet covering with fibrin glue (P=0.01), and more cases that received re-do surgery (P=0.04). IPR was significantly more common in the adhesion group (P<0.01), while contralateral postoperative recurrence did not differ significantly between the groups with and without adhesion (P=0.06). Univariate analyses showed that body mass index (BMI) <15.6 kg/m2 (P<0.01), history of pneumothorax (P=0.01), intraoperative adhesion (P<0.01), upward lung volume >80% (P=0.02), lateral lung volume >80% (P=0.02), 3 fire or more of automatic sutures (P=0.03), and contralateral recurrence (P=0.01) were significant risk factors for IPR. BMI <15.6 kg/m2 (odds ratio: 20.89; 95% confidence interval: 1.55-280.70; P=0.02) and intraoperative adhesion (odds ratio: 25.58; 95% confidence interval: 1.91-342.39; P=0.01) were identified as risk factors for IPR in a multivariate analysis. Conclusions The present findings suggest that low BMI and intraoperative adhesion are risk factors for postoperative recurrence of spontaneous pneumothorax. For such patients, additional intraoperative procedures, such as covering with PGA sheet absorbable oxidized cellulose may be required to reduce postoperative recurrence.

Abstract
Birt-Hogg-Dubé syndrome (BHDS) is a genetic disorder characterized by fibrofolliculomas, renal cell cancer and lung cysts. Patients are at risk to develop pneumothorax but the magnitude of this risk during pregnancy is unknown. Information was obtained from 46 women with BHDS that had at least one pregnancy (BHDS-with preg), 18 female BHDS relatives without pregnancies (BHDS-no preg) and 25 non-BHDS female relatives with at least one pregnancy (noBHDS-with preg). In total, 77 pneumothoraces occurred in the BHDS-with preg group (mean 1.7/patient) and 11 in the BHDS-no preg group. Comparison of patient years for the first two groups showed pneumothorax incidence rates of 0.054 and 0.016, respectively. The incidence rate difference was significant [0.038 (CI 0.02-0.057), value of p-value 0.0001]. This difference is not caused by an increased number of patients with pneumothorax but by an increased number of pneumothoraces per patient. Pregnancy in BHDS therefore might be a risk factor for multiple pneumothoraces.

Abstract
BACKGROUND Primary spontaneous pneumothorax (PSP) has several commonly used management strategies: observation, aspiration, and chest tube placement. Economic modelling of pooled data comparing techniques has not been performed. RESEARCH QUESTION Based on studies from the past 20 years, which approach to management of PSP delivers the highest utility? STUDY DESIGN AND METHODS A systematic review of PSP management strategies (observation, aspiration, or chest tube placement) included in the Medline and EMBASE databases from January 1, 2000, through April 10, 2020, was conducted. Text screening, bias assessment, and data extraction were performed by two authors (G. E. and C. A. P.). Inclusion and exclusion criteria were defined a priori. The primary outcome was PSP resolution after the initial intervention. Secondary outcomes were PSP recurrence, length of stay, rate of surgical management, and complications. The meta-analysis compared treatment arms; dichotomous outcomes were reported as relative risk (RRs) and continuous outcomes were reported as mean differences. A cost-utility analysis within the Canadian health care system context with deterministic and probabilistic sensitivity analyses was performed. RESULTS Five thousand one hundred seventy-nine articles were identified; after screening, 22 articles were included. Most trials showed a high risk of bias, but randomized trials showed a lower risk. Compared with chest tube placement, observation (mean difference, 5.17; 95% CI, 3.75-6.59; P < .01; I2 = 62%) and aspiration (mean difference, 2.72; 95% CI, 2.39-3.04; P < .01; I2 = 0%) showed a shorter length of stay. Compared with observation, chest tube placement (RR, 0.81; 95% CI, 0.71-0.91; P < .01; I2 = 62%) and aspiration (RR, 0.73; 95% CI, 0.61-0.88; P < .01; I2 = 67%) showed higher resolution without additional intervention. Two-year recurrence rates did not differ between management strategies. Observation showed the best utility (0.82) and lowest cost; observation was the optimal strategy in 98.2% of Monte Carlo simulations. INTERPRETATION Observation is the dominant choice compared with aspiration and chest tube placement for PSP. It should be considered as the first-line therapy in appropriately selected patients.

[PMID: 37900247 PMCID: PMC10600998 DOI: 10.12998/wjcc.v11.i27.6415] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/18/2023] [Revised: 08/10/2023] [Accepted: 08/31/2023] [Indexed: 09/20/2023] Open
Abstract
BACKGROUND Chronic obstructive pulmonary disease (COPD) combined with spontaneous pneumothorax, is characterized by significant decline in lung function, and even cause cardiopulmonary failure and hypoxia. AIM To evaluate the clinical effectiveness of central venous catheters and indwelling pleural catheters (IPC) in managing closed thoracic drainage in patients diagnosed with COPD with concomitant by spontaneous pneumothorax. METHODS Retrospective analysis was conducted on the clinical information of 60 elderly patients with COPD complicated by spontaneous pneumothorax admitted to the Shexian Branch of the second affiliated hospital of Zhejiang university school of medicine between March 2020 and March 2023. The clinical efficacy, complications, hospitalization duration, and costs were compared between patients with an indwelling thoracic catheter and those with a central venous catheter. Univariate logistic regression was used to analyze the causes of catheter displacement. RESULTS According to our findings, there were significant differences in the IPC group's clinical efficacy, catheter operation time, and lung recruitment time (P < 0.05). Comparing the complications after catheter treatment between the two groups revealed statistically significant variations in the incidence of postoperative analgesics, catheter abscission, catheter blockage, and subcutaneous emphysema in the IPC group (P < 0.05). Univariate analysis demonstrated significant differences between patients with and without catheter dislodgement regarding duty nurse's working years (less than three), Acute Physiology and Chronic Health Evaluation II (APACHE II) scores (less than 15), lack of catheter suture fixation, and the proportion of catheters not fixed twice (P < 0.05). CONCLUSION Our results demonstrated that when treating elderly COPD patients with spontaneous pneumothorax, indwelling thoracic catheters are more effective than the central venous catheter group. Patients' catheter shedding is influenced by the primary nurse's working years, APACHE II scores, and catheter fixation technique.

SPLF/SMFU/SRLF/SFAR/SFCTCV Guidelines for the management of patients with primary spontaneous pneumothorax. Ann Intensive Care 2023; 13:88. [PMID: 37725198 PMCID: PMC10509123 DOI: 10.1186/s13613-023-01181-2] [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: 07/11/2023] [Accepted: 08/26/2023] [Indexed: 09/21/2023] Open
Abstract
INTRODUCTION Primary spontaneous pneumothorax (PSP) is the presence of air in the pleural space, occurring in the absence of trauma and known lung disease. Standardized expert guidelines on PSP are needed due to the variety of diagnostic methods, therapeutic strategies and medical and surgical disciplines involved in its management. METHODS Literature review, analysis of the literature according to the GRADE (Grading of Recommendation, Assessment, Development and Evaluation) methodology; proposals for guidelines rated by experts, patients and organizers to reach a consensus. Only expert opinions with strong agreement were selected. RESULTS A large PSP is defined as presence of a visible rim along the entire axillary line between the lung margin and the chest wall and ≥ 2 cm at the hilum level on frontal chest X-ray. The therapeutic strategy depends on the clinical presentation: emergency needle aspiration for tension PSP; in the absence of signs of severity: conservative management (small PSP), needle aspiration or chest tube drainage (large PSP). Outpatient treatment is possible if a dedicated outpatient care system is previously organized. Indications, surgical procedures and perioperative analgesia are detailed. Associated measures, including smoking cessation, are described. CONCLUSION These guidelines are a step towards PSP treatment and follow-up strategy optimization in France.

Pneumothorax Trends from 2010-2020 from a Large-Volume Pleural Unit. Pulm Ther 2023; 9:367-375. [PMID: 37415030 PMCID: PMC10447695 DOI: 10.1007/s41030-023-00232-0] [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: 05/04/2023] [Accepted: 06/15/2023] [Indexed: 07/08/2023] Open
Abstract
INTRODUCTION Previous studies in 2018 and 2022 have suggested increasing inpatient burden of pneumothorax and widespread variation in management. Local trends have never been elucidated. Northumbria Healthcare NHS Foundation Trust (NHCT) has a well-established pleural service, serving just over 600,000. Thus, we set up a local retrospective study to look at trends in pneumothorax presentation, management strategies, length of stay, and recurrence. METHODS A coding search for 'pneumothorax' was performed for all patients attending NHCT between 2010 and 2020 was performed with local Caldicott approval. A total of 1840 notes were analysed to exclude iatrogenic, traumatic, and paediatric events. After excluding those cases, 580 remained for further analysis, consisting of 183 primary pneumothoraces (PSP) and 397 secondary pneumothoraces (SSP). RESULTS Median age for PSP was 26.5 years (IQR 17) with 69% male, and for SSP 68 years (IQR 11.5), 62% male; 23.5% of PSP and 8.6% of SSP were never smokers. The proportion of smokers and ex-smokers has not really changed over time: > 65% every year have been smokers or ex-smokers. Yearly pneumothorax incidence shows a downward trend for PSP but upwards for SSP. Median length of stay (LoS) for PSP was 2 days (IQR 2), and SSP 5 days (IQR 8), with a clear downward trend. From 2010 to 2015 > 50% PSP were managed with drain, but in 2019-2020 at least 50% managed conservatively, with a significant reduction in aspiration. Trends of recurrence for PSP are increasing, whereas for SSP is decreasing. Seventy-six (20 PSP, 56 SSP) went for surgery at the index time with 5.3% recurrence (20% recurrence in those without surgery). CONCLUSIONS This is the first known analysis of pneumothorax trends in a large trust in the northeast of England. The data in this study have certain limitations, including the lack of information on the size of pneumothorax and frailty indicators that may influence the decision for conservative management. Additionally, there is a reliance on clinical coding, which can introduce potential inaccuracies, and not all patient notes were accessible for analysis. Updated larger datasets should help elucidate trends better.

Utility of the endobronchial Watanabe spigot for intractable cancer-related pneumothorax: a retrospective observational study. Jpn J Clin Oncol 2023; 53:829-836. [PMID: 37340759 PMCID: PMC10473273 DOI: 10.1093/jjco/hyad060] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/09/2023] [Accepted: 05/25/2023] [Indexed: 06/22/2023] Open
Abstract
BACKGROUND The use of endobronchial Watanabe spigots for intractable secondary pneumothorax in patients with cancer has not been adequate. This study aimed to investigate the use of endobronchial Watanabe spigots for intractable pneumothorax in patients with malignant tumors. METHODS Consecutive patients with malignant tumors who underwent occlusion with an endobronchial Watanabe spigot for intractable pneumothorax associated with perioperative treatment or drug therapy at our institution between January 2014 and February 2022 were reviewed. RESULTS Of the 32 cases in which an endobronchial Watanabe spigot was used, six were excluded; we thus evaluated 26 cases in which the chest tube was removed. Chest tubes were removed in 19 cases (73.1%) and could not be removed and required surgical treatment under general anesthesia in seven patients (26.9%), of which four (14.8%) underwent open-window thoracostomy. Half of the patients were treated with both an endobronchial Watanabe spigot and pleurodesis. Although thin-slice chest computed tomography revealed a fistula in 15 patients, the chest tube was removed in 11 (57.9%) patients. A significant difference was only observed in patients with a history of heavy smoking. CONCLUSIONS The chest tube removal rate was comparable to those reported in previous studies. An endobronchial Watanabe spigot may be a useful treatment option for intractable cancer-related pneumothorax.

Thoracic Endometriosis Syndrome (TES) in Martinique, a French West Indies Island. J Clin Med 2023; 12:5578. [PMID: 37685644 PMCID: PMC10488738 DOI: 10.3390/jcm12175578] [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: 07/18/2023] [Revised: 08/21/2023] [Accepted: 08/24/2023] [Indexed: 09/10/2023] Open
Abstract
INTRODUCTION Endometriosis is a female disease that affects 5-10% of women of childbearing age, with predominantly pelvic manifestations. It is currently declared as a public health priority in France. Thoracic endometriosis syndrome (TES) is the most common extra-pelvic manifestation. OBJECTIVE The objective of this study was to describe the epidemiological and clinical characteristics, and outcomes of patients with TES in Martinique. PATIENTS AND METHODS We performed a descriptive, retrospective study including all patients managed at the University Hospital of Martinique for TES between 1 January 2004 and 31 December 2020. RESULTS During the study period, we identified 479 cases of pneumothorax, of which 212 were women (44%). Sixty-three patients (30% of all female pneumothorax) were catamenial pneumothorax (CP) including 49 pneumothoraxes alone (78% of catamenial pneumothorax) and 14 hemopneumothorax (22% of catamenial pneumothorax). There were 71 cases of TES, including 49 pneumothoraxes (69%), 14 hemopneumothoraxes (20%) and 8 hemothorax (11%). The annual incidence of TES was 1.1 cases/100,000 inhabitants. The prevalence of TES was 1.2/1000 women aged from 15 to 45 years and the annual incidence of TES for this group was 6.9/100,000. The annual incidence of CP was 1 case/100,000 inhabitants. The average age at diagnosis was 36 ± 6 years. Eight patients (11%) had no prior diagnosis of pelvic endometriosis (PE). The mean age at pelvic endometriosis diagnosis was 29 ± 6 years. The mean time from symptom onset to diagnosis was 24 ± 50 weeks, and 53 ± 123 days from diagnosis to surgery. Thirty-two patients (47%) had prior abdominopelvic surgery. Seventeen patients (24%) presented other extra-pelvic localizations. When it came to management, 69/71 patients (97%) underwent surgery. Diaphragmatic nodules or perforations were found in 68/69 patients (98.5%). Histological confirmation was obtained in 55/65 patients who underwent resection (84.6%). Forty-four patients (62%) experienced recurrence. The mean time from the initial treatment to recurrence was 20 ± 33 months. The recurrence rate was 16/19 (84.2%) in patients who received medical therapy only, 11/17 (64.7%) in patients treated by surgery alone, and 17/31 (51.8%) in patients treated with surgery and medical therapy (p = 0.03). CONCLUSIONS We observed a very high incidence of TES in Martinique. The factors associated with this high incidence in this specific geographical area remain to be elucidated. The frequency of recurrence was lower in patients who received both hormone therapy and surgery.

Trends in recurrence of primary spontaneous pneumothorax in young population after treatment for first episode based on a nationwide population data. Sci Rep 2023; 13:13478. [PMID: 37596298 PMCID: PMC10439191 DOI: 10.1038/s41598-023-39717-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/02/2023] [Accepted: 07/29/2023] [Indexed: 08/20/2023] Open
Abstract
The aim of this study is to identifying post treatment recurrence rates in pneumothorax patients under 35 and without any comorbidities according to the treatment types, gender, and age categories based on nationwide population data. Clinical information of pneumothorax patients was extracted from the Korean National Health Insurance Service (NHIS) database between January 2002 and December 2020. Enrolled patients were categorized into two groups; (1) Group I, those who underwent conservative management including pain relief, oxygen therapy, and closed thoracostomy, and (2) Group II, surgical intervention. Recurrence rates were compared according to age, gender, and type of treatment. Surgical intervention was performed in 25.6% patients as first treatment. The overall recurrence rate was 20.3%. Male patients showed a higher 5-year recurrence rate than female (20.8% vs. 10.9%, p < 0.001). Those with conservative management showed lower 5-year recurrence rates than those with surgical treatment (7.9% vs. 23.7%, p < 0.001). The 5-year recurrence rates of patients aged 14≤, and < 20 was higher than other age groups (29.2% vs. 4.5 and 11.9%, p < 0.001). Surgical intervention, male gender and aged under 20 showed association with higher recurrence rates.

Abstract
Coronavirus disease 2019 (COVID-19)-related pleural diseases are now well recognized. Since the beginning of the pandemic, increasing cases of pleural diseases including pneumothorax, pneumomediastinum, and pleural effusion with severe COVID-19 infection have attracted the attention of physicians and are not incidental or due to barotrauma. The complicated course of COVID-19 illness highlights the complex pathophysiological underpinnings of pleural complications. The management of patients with pneumothorax and pneumomediastinum is challenging as the majority require assisted ventilation; physicians therefore appear to have a low threshold to intervene. Conversely, pleural effusion cases, although sharing some similar patient characteristics with pneumothorax and pneumomediastinum, are in general managed more conservatively. The evidence suggests that patients with COVID-19-related pleural diseases, either due to air leak or effusion, have more severe disease with a worse prognosis. This implies that prompt recognition of these complications and targeted management are key to improve outcomes.

Probability of sporadic lymphangioleiomyomatosis in women presenting with spontaneous pneumothorax. Orphanet J Rare Dis 2023; 18:180. [PMID: 37415209 DOI: 10.1186/s13023-023-02784-5] [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: 03/01/2023] [Accepted: 06/18/2023] [Indexed: 07/08/2023] Open
Abstract
BACKGROUND Sporadic lymphangioleiomyomatosis (S-LAM) is a rare low-grade neoplasm of young women characterized by multiple pulmonary cysts leading to progressive dyspnea and recurrent spontaneous pneumothorax (SP). The diagnosis of S-LAM may be delayed by several years. To reduce this delay, chest computed tomography (CT) screening has been proposed to uncover cystic lung disease in women presenting with SP. However, the probability to discover S-LAM in this population has not been determined precisely. The aim of this study was to calculate the probability of finding S-LAM in women presenting with (a) SP, and (b) apparent primary SP (PSP) as first manifestation of S-LAM. METHODS Calculations were made by applying the Bayes theorem to published epidemiological data on S-LAM, SP and PSP. Each term of the Bayes equation was determined by meta-analysis, and included: (1) the prevalence of S-LAM in the general female population, (2) the incidence rate of SP and PSP in the general female population, and (3) the incidence rate of SP and apparent PSP in women with S-LAM. RESULTS The prevalence of S-LAM in the general female population was 3.03 per million (95% confidence interval 2.48, 3.62). The incidence rate of SP in the general female population was 9.54 (8.15, 11.17) per 100,000 person-years (p-y). The incidence rate of SP in women with S-LAM was 0.13 (0.08, 0.20). By combining these data in the Bayes theorem, the probability of finding S-LAM in women presenting with SP was 0.0036 (0.0025, 0.0051). For PSP, the incidence rate in the general female population was 2.70 (1.95, 3.74) per 100,000 p-y. The incidence rate of apparent PSP in women with S-LAM was 0.041 (0.030, 0.055). With the Bayes theorem, the probability of finding S-LAM in women presenting with apparent PSP as first disease manifestation was 0.0030 (0.0020, 0.0046). The number of CT scans to perform in women to find one case of S-LAM was 279 for SP and 331 for PSP. CONCLUSION The probability of discovering S-LAM at chest CT in women presenting with apparent PSP as first disease manifestation was low (0.3%). Recommending chest CT screening in this population should be reconsidered.

Abstract
For decades, there has been scanty evidence, most of which is of poor quality, to guide clinicians in the assessment and management of pneumothorax. A recent surge in pneumothorax research has begun to address controversies surrounding the topic and change the face of pneumothorax management. In this article, we review controversies concerning the etiology, pathogenesis, and classification of pneumothorax, and discuss recent advances in its management, including conservative and ambulatory management. We review the evidence base for the challenges of managing pneumothorax, including persistent air leak, and suggest new directions for future research that can help provide patient-centered, evidence-based management for this challenging cohort of patients.

Abstract
Subcutaneous emphysema, pneumothorax and pneumomediastinum are well-known complications of invasive ventilation in patients with acute hypoxemic respiratory failure. We determined the incidences of air leaks that were visible on available chest images in a cohort of critically ill patients with acute hypoxemic respiratory failure due to coronavirus disease of 2019 (COVID-19) in a single-center cohort in the Netherlands. A total of 712 chest images from 154 patients were re-evaluated by a multidisciplinary team of independent assessors; there was a median of three (2-5) chest radiographs and a median of one (1-2) chest CT scans per patient. The incidences of subcutaneous emphysema, pneumothoraxes and pneumomediastinum present in 13 patients (8.4%) were 4.5%, 4.5%, and 3.9%. The median first day of the presence of an air leak was 18 (2-21) days after arrival in the ICU and 18 (9-22)days after the start of invasive ventilation. We conclude that the incidence of air leaks was high in this cohort of COVID-19 patients, but it was fairly comparable with what was previously reported in patients with acute hypoxemic respiratory failure in the pre-COVID-19 era.

Abstract
Introduction : Le pneumothorax spontané primaire (PSP) est un épanchement gazeux dans la cavité pleurale, survenant hors traumatisme et pathologie respiratoire connue. Des recommandations formalisées d'experts sur le sujet sont justifiées par les pluralités de moyens diagnostiques, stratégies thérapeutiques et disciplines médicochirurgicales intervenant dans leur prise en charge.
Méthodes : Revue bibliographique, analyse de la littérature selon méthodologie GRADE (Grading of Recommendation Assessment, Development and Evaluation) ; propositions de recommandations cotées par experts, patients et organisateurs pour obtenir un consensus. Seuls les avis d'experts avec accord fort ont été retenus.
Résultats : Un décollement sur toute la hauteur de la ligne axillaire et supérieur ou égal à 2 cm au niveau du hile à la radiographie thoracique de face définit la grande abondance. La stratégie thérapeutique dépend de la présentation clinique : exsufflation en urgence pour PSP suffocant ; en l'absence de signe de gravité : prise en charge conservatrice (faible abondance), exsufflation ou drainage (grande abondance). Le traitement ambulatoire est possible si organisation en amont de la filière. Les indications, procédures chirurgicales et l'analgésie périopératoire sont détaillées. Les mesures associées, notamment le sevrage tabagique, sont décrites.
Conclusion : Ces recommandations sont une étape de l'optimisation des stratégies de traitement et de suivi des PSP en France.

Abstract
BACKGROUND Contralateral bullae/blebs are frequently found in patients who are scheduled to undergo ipsilateral video-assisted thoracoscopic surgery (VATS) for primary spontaneous pneumothorax (PSP). RESEARCH QUESTION Should visible contralateral bullae/blebs be simultaneously resected when ipsilateral VATS bullectomy is performed? STUDY DESIGN AND METHODS In this single-center, retrospective cohort study, we included patients aged ≤ 30 years who underwent ipsilateral VATS for PSP from April 2009 to December 2019. Electronic medical records, radiograph images, and preoperative high-resolution CT images were reviewed. The primary end point was recurrence-free survival (no contralateral pneumothorax) after discharge of ipsilateral VATS for PSP, determined via Kaplan-Meier analysis. Recurrence was compared between the group with and that without contralateral bullae/blebs by using the log-rank test. A multivariable Cox proportional hazards model was constructed to investigate risk factors for contralateral pneumothorax. RESULTS Among 567 patients, contralateral pneumothorax occurred in 86 of them after ipsilateral VATS (15.2%) during a median follow-up period of 51.3 (interquartile range, 67.2) months. The 1-, 5-, and 10-year recurrence-free survival rates were 92.2%, 83.7%, and 79.9%, respectively. Contralateral recurrence was higher in the group with (82/455, 18.0%) than in that without (4/112, 3.6%) contralateral bullae/blebs (P < .001). Age (hazard ratio [HR], 0.701; 95% CI, 0.629-0.780; P < .001), current smoking (HR, 2.106; 95% CI, 1.158-3.831; P = .015), and the presence of bullae/blebs (increasing with size, HR, 4.818-8.980; all P < .05) were independent risk factors for contralateral pneumothorax. The annual rates of contralateral pneumothorax in the group with (4.0%) and in that without (0.7%) contralateral bullae/blebs declined over time. INTERPRETATION Although contralateral bullae/blebs were common in patients who underwent ipsilateral VATS for PSP and were statistically significantly associated with future pneumothorax, the annual rate of pneumothorax was 4.0% in such patients, and it decreased over time. Therefore, a conservative approach on unruptured contralateral bullae/blebs is recommended.

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
Purpose: A pneumothorax occurs in 3%–8% of patients with idiopathic pulmonary fibrosis. A pneumothorax may predict a poor outcome in patients with interstitial lung disease (ILD), and it is difficult to treat patients with ILD and a pneumothorax. Patients and Methods: We retrospectively studied data from all 12 patients with ILD and a pneumothorax who underwent surgical treatment at Toho University Omori Medical Center Hospital between 2009 and 2021. Results: Of the 12 patients, 2 had home oxygen therapy preoperatively and were classified with grade IV interstitial pneumonia (IP). Six patients had preoperative pleurodesis and two had postoperative one using auto-blood. Three patients (25%) had multi-step surgery ≥2, and 5 patients had surgical resection of bullae. No patients had postoperative acute exacerbations and all were discharged from the hospital in a stable condition. The 5-year overall survival rate for all patients was 70.0%. The median survival time was not reached. One patient with unclassified IP was doing well 116 months after surgery. Conclusion: Patients with ILD and a pneumothorax were shown to require multi-step surgical treatment and can anticipate long-term survival.

Abstract
COVID-19 is a multi-system disease caused by severe acute respiratory syndrome-coronavirus 2 (SARS-CoV-2). One of the main highlights of the disease is the development of pneumonia complicated by adult respiratory distress syndrome. While spontaneous pneumothorax has been reported in some patients with COVID-19, bronchopleural fistula has seldom been reported as the primary cause in these cases. We describe the rare case of a young patient who developed a pneumothorax complicating COVID-19 and was found to have a bronchopleural fistula and empyema secondary to Staphylococcus aureus superinfection.

Abstract
Background The major brunt of coronavirus disease-2019 (COVID-2019) is borne by the lungs. The major cause of morbidity and mortality in COVID-19 patients is a compromise of the respiratory system. Pneumothorax is noted as an insignificant proportion of patients suffering from COVID-19, but it jeopardizes the clinical recovery significantly. We, in the case series of 10 patients, will be summarizing the epidemiological, demographic, and clinical characteristics of COVID-19 patients who also developed pneumothorax. Patients and methods All the confirmed cases of COVID-19 pneumonia diagnosed between May 1, 2020 and August 30, 2020, admitted at our center meeting the inclusion criteria and whose clinical course was complicated by pneumothorax were made part of our study. Their clinical records were studied, and epidemiological, demographic, and clinical data of these patients were collected and compiled in this case series. Results All the patients in our study required ICU care, and 60% received non-invasive mechanical ventilation, while 40% of the patients progressed to intubation and invasive mechanical ventilation. A total of 70% of the patients in our study had a successful outcome, while 30% succumbed to the disease and expired. Conclusion Epidemiological, demographic, and clinical characteristics of COVID-19 patients complicated with pneumothorax were evaluated. Our study showed that pneumothorax also developed in some patients who had not received mechanical ventilation, indicating that pneumothorax could be a secondary complication of SARS-CoV-2 infection. Our study also emphasizes the fact that even the majority of patients whose clinical course was complicated by pneumothorax had a successful outcome emphasizing the need for timely and adequate intervention in such cases.

Meta-analysis of the association between emphysematous change on thoracic computerized tomography scan and recurrent pneumothorax. QJM 2022; 115:215-221. [PMID: 33538832 PMCID: PMC9020478 DOI: 10.1093/qjmed/hcab020] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/15/2020] [Revised: 01/19/2021] [Indexed: 11/30/2022] Open
Abstract
OBJECTIVES At least a third of patients go on to suffer a recurrence following a first spontaneous pneumothorax. Surgical intervention reduces the risk of recurrence and has been advocated as a primary treatment for pneumothorax. But surgery exposes patients to the risks of anaesthesia and in some cases can cause chronic pain. Risk stratification of patients to identify those most at risk of recurrence would help direct the most appropriate patients to early intervention. Many studies have addressed the role of thoracic computerized tomography (CT) in identifying those individuals at increased risk of recurrence, but a consensus is lacking. AIM Our objective was to clarify whether CT provides valuable prognostic information for recurrent pneumothorax. DESIGN Meta-analysis. METHODS We conducted an exhaustive search of the literature for thoracic CT imaging and pneumothorax, and then performed a meta-analysis using a random effects model to estimate the common odds ratio and standard error. RESULTS Here, we show by meta-analysis of data from 2475 individuals that emphysematous change on CT scan is associated with a significant increased odds ratio for recurrent pneumothorax ipsilateral to the radiological abnormality (odds ratio 2.49, 95% confidence interval 1.51-4.13). CONCLUSIONS The association holds true for primary spontaneous pneumothorax when considering emphysematous changes including blebs and bullae. Features, such as bullae at the azygoesophageal recess or increased Goddard score similarly predicted recurrent secondary pneumothorax, as shown by subgroup analysis. Our meta-analysis suggests that CT scanning has value in risk stratifying patients considering surgery for pneumothorax.

Abstract
BACKGROUND Ambulatory management of primary spontaneous pneumothorax has been shown to reduce initial hospitalisation, but at the expense of increase adverse events. As a result, questions remain about the cost-effectiveness of this option. OBJECTIVES A within-trial economic evaluation alongside a randomised controlled trial was performed to assess the cost-effectiveness of ambulatory care when compared with standard guideline-based management. METHODS Patients were randomly assigned to treatment with either an ambulatory device or standard guideline-based management (aspiration, standard chest tube insertion or both). Follow-up was 12 months. Outcomes included healthcare resource use and costs, quality of life, quality-adjusted life-years (QALYs) and cost-effectiveness. RESULTS 236 patients were recruited and randomly assigned to ambulatory care (n=117) and standard care (n=119). After multiple imputation for missing data, patients in the ambulatory care group had significantly lower National Health Service healthcare costs (-£788, 95% CI difference: -1527 to -50; p=0.037) than those in the standard care group. There were no differences in the number of QALYs gained (mean difference: -0.001, 95% CI difference: -0.032 to 0.030; p=0.95). When standard care was compared with ambulatory care, the incremental cost-effectiveness ratio was £799 066 per QALY gained, well above current thresholds of cost-effectiveness. As a result, the probability of ambulatory care being cost-effective was 0.93. CONCLUSION Outpatient ambulatory management is highly likely to be a cost-effective option in the management of primary pneumothorax. TRIAL REGISTRATION NUMBER ISRCTN79151659.

Abstract
Secondary spontaneous pneumothorax (SSP) is a medical emergency where the lung collapses in the presence of underlying chronic lung disease. It is the commonest cause of spontaneous pneumothorax and results in significant breathlessness, higher morbidity, mortality, and longer hospital admissions than with patients with pneumothoraces and no underlying lung disease. This article explores the current guidance, controversies, and recent advances in the management of this condition.

Abstract
Background and objective Spontaneous pneumothorax is a common pathology but optimal initial treatment regime is not well defined. Treatment options including conservative management, needle aspiration (NA) or insertion of a small-bore chest drain. Recent large randomised controlled trials may change the treatment paradigm: comparing conservative and ambulatory management to standard care, but current guidelines need to be updated. The aim of this study was to assess the current “state of play” in the management of pneumothorax in the UK. Methods Physicians and respiratory healthcare staff were invited to complete an online survey on the initial and subsequent management of pneumothorax. Results This study is the first survey of pneumothorax practice across the UK, which highlights variation in practice: 50% would manage a large primary pneumothorax with minimal symptoms conservatively, compared to only 3% if there were significant symptoms; 64% use suction if the pneumothorax had not resolved after > 2 days, 15% always clamp the chest drain prior to removal; whereas 30% never do. NICE guidance recommends the use of digital suction but this has not translated into widespread usage: only 23% use digital suction to check for resolution of air leak). Conclusion Whilst there has always been allowance for individual clinician preference in guidelines, there needs to be consensus on the optimum management strategy. The challenge the new guidelines face is to design a simple and pragmatic approach, using this new evidence base.

Abstract
BACKGROUND The purpose of this study was to clarify the efficacy of the combination of low-voltage coagulation plus staple line coverage with a polyglycolic acid sheet after bullectomy for primary spontaneous pneumothorax to prevent a postoperative recurrence. METHODS A total of 143 patients who underwent bullectomy for primary spontaneous pneumothorax between January 2014 and December 2019 were enrolled in this study. We classified the patients into two groups based on additional procedures after bullectomy, namely, low-voltage coagulation for the margin of the staple line plus coverage with a polyglycolic acid sheet (Group A) and staple line coverage with a polyglycolic acid sheet alone (Group B). We evaluated perioperative factors and recurrence-free survival after surgery in the two groups. RESULTS Nine patients in Group B developed postoperative recurrences. In contrast, there was no postoperative recurrence in Group A. According to the Kaplan-Meier curves, the 2-year recurrence-free survival rates of the patients were 100% and 90.3%, in Group A and Group B, respectively. The log-rank test showed a significant difference between the two groups (p = 0.031). CONCLUSION Low-voltage coagulation for the margin of a staple line plus coverage with a polyglycolic acid sheet is a useful option as an additional technique after bullectomy for primary spontaneous pneumothorax to prevent a postoperative recurrence.

Abstract
Purpose Primary spontaneous pneumothorax (PSP) is an urgent/emergency condition. Treatment with intercostal chest drainage (ICD) is necessary, particularly in symptomatic patients or those with tension. A previous study found that systematic breathing exercise significantly reduced ICD duration when compared with controls. This study aimed to evaluate if pulmonary rehabilitation can reduce the duration of ICD treatment in patients with PSP. Patients and Methods This was a retrospective study of patients diagnosed with PSP treated with ICD. Duration of ICD treatment was recorded from patients' medical charts. Factors associated with ICD duration were calculated using linear regression analysis. Results There were 66 patients who met the study criteria, with average (SD) age and body mass index of 31.68 (13.53) years and 20.94 (2.72) kg/m2. The majority of the patients were male (72.73%), and average (SD) duration of ICD treatment was 9.90 (7.83) days. Three factors remained in the final model: body mass index, systolic blood pressure, and recurrent PSP. Two factors were independently associated with longer ICD duration: systolic blood pressure and recurrent PSP, with adjusted coefficients of 0.21 (p value 0.041) and 7.69 (p value 0.039), respectively. Pulmonary rehabilitation was not included in the final model. Conclusion Patients with a history of recurrent PSP or high systolic blood pressure at presentation may require longer ICD duration. Pulmonary rehabilitation was not associated with the duration of ICD treatment.

Abstract
INTRODUCTION Thoracoscopic surgery is performed for refractory or recurrent primary spontaneous pneumothorax (PSP). To reduce postoperative recurrence, additional treatment is occasionally adopted during surgery after bulla resection. However, the most effective method has not been fully elucidated. Furthermore, the preference for additional treatment varies among countries, and its efficacy in preventing recurrence must be evaluated based on settings tailored for the conditions of a specific country. The number of registries collecting detailed data about PSP surgery is limited. Therefore, to address this issue, a prospective multicentre observational study was performed. METHODS AND ANALYSIS This multicentre, prospective, observational study will enrol 450 participants aged between 16 and 40 years who initially underwent PSP surgery. Data about demographic characteristics, disease and family history, surgical details, and CT scan findings will be collected. Follow-up must be conducted until 3 years after surgery or in the event of recurrence, whichever came first. Patients without recurrence will undergo annual follow-up until 3 years after surgery. The primary outcome is the rate of recurrence within 2 years after surgery. A multivariate analysis will be performed to compare the efficacy of different surgical options. Then, adverse outcomes correlated with various treatments and the feasibility of treatment methods will be compared. ETHICS AND DISSEMINATION This study was approved by the local ethics committee of all participating centres. The findings will be available in 2025, and they can be used as a basis for clinical decision-making regarding appropriate options for the initial PSP surgery. TRIAL REGISTRATION NUMBER NCT04758143.

Abstract
INTRODUCTION CT imaging is not advocated by British Thoracic Society guidelines after first episode of primary spontaneous pneumothorax (PSP). There is emerging evidence that emphysema-like changes and CT-based dystrophy severity score (DSS) can predict need for early surgery and recurrence. OBJECTIVES We aimed to assess the role of DSS during first episodes of PSP in predicting the need for early surgery and recurrence. METHODS We conducted a retrospective analysis of consecutive PSP episodes (n=197) admitted to our institution from 1 January 2012 to 31 December 2017. DSS was calculated based on type, number and distribution of blebs and bullae. Patients were categorised as low-grade (0-3) or high-grade (4-6) DSS assessed by a thoracic radiologist. RESULTS Forty-five PSP patients had CT at first presentation. Eight patients had low-grade DSS; all were managed non-surgically and none had recurrence over 12 months. Thirty-seven patients had high-grade DSS. Of these, 25 (67.5%) were managed surgically, with three having contralateral recurrence over 12 months; 12 (32.5%) were managed non-surgically, and of these two patients had ipsilateral recurrence over 12 months. CONCLUSION DSS seems to predict the need for early surgery and recurrence and CT can be used to risk-stratify patients after a first episode of PSP.

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 problem worldwide. Pneumothorax develops secondary to diverse aetiologies; in many cases, there may be no recognizable lung abnormality. The pathogenetic mechanism(s) causing spontaneous pneumothorax may be related to an interplay between lung-related abnormalities and environmental factors such as smoking. Tobacco smoking is a major risk factor for primary spontaneous pneumothorax; chronic obstructive pulmonary disease is most frequently associated with secondary spontaneous pneumothorax. This review article provides an overview of the historical perspective, epidemiology, classification, and aetiology of pneumothorax. It also aims to highlight current knowledge and understanding of underlying risks and pathophysiological mechanisms in pneumothorax development.

Abstract
Outpatient Management of Primary Spontaneous Pneumothorax Abstract. Pneumothorax (PT) is defined as a collapse of the lung due to the collection of air in the pleural space. In primary spontaneous pneumothorax (PSP) there is no underlying pulmonary pathology. Treatment, either conservative or invasive, depends on the size of the PT, the patient's clinical situation and the patient's setting/environment. According to the actual literature, the uncomplicated PSP can at best be treated conservatively and on an outpatient basis. Management with intervention (needle aspiration or chest drainage) is historically carried out on an inpatient basis, but outpatient management (without comorbidities and without symptoms) is also possible. In these cases, the patient compliance (motivation, cognition, support, housing situation …) has to be proven. For outpatient management with intervention, a small-caliber chest tube (<14 F) with a Heimlich valve should be used.

Abstract
Video-assisted thoracic surgery (VATS) is the treatment of choice for recurrence prevention in patients with spontaneous pneumothorax (SP). Although the optimal surgical technique is uncertain, bullous resection using staplers in combination with mechanical pleurodesis, chemical pleurodesis and/or staple line coverage is usually undertaken. Currently, patient satisfaction, postoperative pain and other perioperative parameters have significantly improved with advancements in thoracoscopic technology, which include uniportal, needlescopic and nonintubated VATS variants. Ipsilateral recurrences after VATS occur in less than 5% of patients, in which case a redo-VATS is a feasible therapeutical option. Randomized controlled trials are urgently needed to shed light on the best definitive management of SP.

Abstract
Abstract
Purpose of Review
The aim of this paper is to present basic data on pleural manometry and to outline the advances in its use as both a research tool enabling a better understanding of pleural pathophysiology and as a clinical tool useful in management strategy planning in patients with pleural diseases. To discuss updates and current trends in the development of pleural manometry, a search of the literature on pleural manometry published in recent years was performed.
Recent Findings
The technique of pleural manometry has significantly evolved over the last 40 years from simple water manometers to electronic or digital devices which enable the measurement and recording of instantaneous pleural pressure. Although to date it is mainly used as a research tool, pleural manometry has the potential to be applied in clinical practice. Recent studies demonstrated that monitoring of pleural pressure changes during therapeutic thoracentesis does not seem to be helpful in predicting re-expansion pulmonary edema and procedure-related chest discomfort. On the other hand, measurement of pleural elastance plays an important role in the diagnosis of unexpandable lung in patients with malignant pleural effusion facilitating determination of the optimal management strategy. Additionally, it allows for study of newly discovered phenomena, including pleural pressure pulse assessment and the impact of continuous positive airway pressure and cough on pleural pressure.
Summary
Pleural manometry is an established technique of pleural pressure measurement. Despite recent advances, its role in clinical practice remains undetermined.

Abstract
BACKGROUND Primary spontaneous pneumothorax (PSP) is a condition that may lead to acute chest pain or dyspnea on exertion. Treatment with an intercostal chest drainage (ICD) is warranted. There is limited data on risk factors of recurrent PSP in patients treated with the ICD alone. This study aimed to evaluate risk factors of recurrent PSP in patients with PSP and treated with the ICD. METHODS This was a retrospective study and enrolled patients diagnosed as PSP and treated with an ICD. Eligible patients were divided into two groups by evidence of recurrent PSP. Baseline characteristics, physical signs, laboratory results, and duration of ICD treatment were studied and recorded from medical charts. Factors associated with recurrent PSP were computed by using multivariate logistic regression analysis. RESULTS There were 80 patients met the study criteria. Of those, 21 patients (26.3%) had recurrent PSP. Of those, 21 patients (26.3%) had recurrent PSP. There were eight factors in the final model for recurrent PSP. Only oxygen saturation at the time of diagnosis was independently associated with recurrent PSP. The adjusted odds ratio (95% confident interval) was 0.57 (0.34, 0.96). A cut point of 96% of oxygen saturation gave sensitivity of recurrent PSP of 80.95%. CONCLUSION The prevalence of recurrent PSP was 26.3% in patients with PSP and treated with the ICD. Initial oxygen saturation may be an indicator for recurrent PSP.
