Abstract
BACKGROUND Patients with persistent air leak (PAL) pose a therapeutic challenge to physicians, with prolonged hospital stays and high morbidity. There is little evidence on the efficacy and safety of bronchial valves (BV) for PAL. METHODS We systematically searched the PubMed and Embase databases to identify studies evaluating the efficacy and safety of BV for PAL. We calculated the success rate (complete resolution of air leak or removal of intercostal chest drain after bronchial valve placement and requiring no further procedures) of BV for PAL in individual studies. We pooled the data using a random-effects model and examined the factors influencing the success rate using multivariable meta-regression. RESULTS We analyzed 28 observational studies (2472 participants). The pooled success rate of bronchial valves in PAL was 82% (95% confidence intervals, 75 to 88; 95% prediction intervals, 64 to 92). We found a higher success rate in studies using intrabronchial valves versus endobronchial valves (84% vs. 72%) and in studies with more than 50 subjects (93% vs. 77%). However, none of the factors influenced the success rate of multivariable meta-regression. The overall complication rate was 9.1% (48/527). Granulation tissue was the most common complication reported followed by valve migration or expectoration and hypoxemia. CONCLUSION Bronchial valves are an effective and safe option for treating PAL. However, the analysis is limited by the availability of only observational data.

Abstract
OBJECTIVES The optimal management for spontaneous pneumothorax (SP) remains contentious, with various proposed approaches. This joint clinical practice guideline from the ERS, EACTS and ESTS societies provides evidence-based recommendations for the management of SP. METHODS This multidisciplinary Task Force addressed 12 key clinical questions on the management of pneumothorax, using ERS methodology for guideline development. Systematic searches were performed in MEDLINE and Embase. Evidence was synthesised by conducting meta-analyses, if possible, or narratively. Certainty of evidence was rated with GRADE (Grading, Recommendation, Assessment, Development and Evaluation). The Evidence to Decision framework was used to decide on the direction and strength of the recommendations. RESULTS The panel makes a conditional recommendation for conservative care of minimally symptomatic patients with primary spontaneous pneumothorax (PSP) who are clinically stable. We make a strong recommendation for needle aspiration over chest tube drain for initial PSP treatment. We make a conditional recommendation for ambulatory management for initial PSP treatment. We make a conditional recommendation for early surgical intervention for the initial treatment of PSP in patients who prioritise recurrence prevention. The panel makes a conditional recommendation for autologous blood patch in secondary SP patients with persistent air leak (PAL). The panel could not make recommendations for other interventions, including bronchial valves, suction, pleurodesis in addition to surgical resection or type of surgical pleurodesis. CONCLUSIONS With this international guideline, the ERS, EACTS and ESTS societies provide clinical practice recommendations for SP management. We highlight evidence gaps for the management of PAL and recurrence prevention, with research recommendations made. SHAREABLE ABSTRACT This update of an ERS Task Force statement from 2015 provides a concise comprehensive update of the literature base. 24 evidence-based recommendations were made for management of pneumothorax, balancing clinical priorities and patient views.https://bit.ly/3TKGp9e.

Abstract
INTRODUCTION Persistent air leaks (PAL) represent a challenging clinical problem for which there is not a clear consensus to guide optimal management. PAL is associated with significant morbidity, mortality, and increased length of hospital stay. There are a variety of surgical and non-surgical management options available. AREAS COVERED This narrative review describes the current evidence for PAL management including surgical approach, autologous blood patch pleurodesis, chemical pleurodesis, endobronchial valves, and one-way valves. Additionally, emerging topics such as drainage-dependent air leak and intensive care unit management are described. EXPERT OPINION There has been considerable progress in understanding the pathophysiology of PAL and growing evidence to support the various non-surgical treatment modalities. Increased recognition of drainage-dependent persistent air leaks offers the opportunity to decrease the number of patients requiring additional invasive treatment. Randomized control trials are needed to guide optimal management.

Abstract
Background Persistent air leak (PAL) is common in secondary spontaneous pneumothorax (SSP), with risk factors only been determined for post-pulmonary resection PAL. Information about its risk factors and long-term outcome is, however, necessary to enable selection of treatment modalities for elderly SSP patients with comorbid conditions. Methods A retrospective observational study was performed on chest drain-treated SSP patients from 2009 to 2018. The risk factors, long-term recurrent pneumothorax, and mortality rates of those with and without PAL were evaluated. Results Of 180 non-surgical SSP patients, PAL prevalence for >2 days and >7 days were 81.1% and 43.3%, respectively. Bulla was associated with PAL >7 days (OR: 2.32; P: 0.027) and serum albumin negatively associated (OR: 0.94; P: 0.028). PAL resulted in longer hospitalization in the index episode (P: <0.01). PAL >7 days was associated with a higher pneumothorax recurrence rate in three months (HR: 2.65; P: 0.041), one year (HR: 2.50; P: 0.040) and two-year post-discharge (HR: 2.40; P: 0.029). Patients treated with medical pleurodesis were significantly older (P: <0.01), had higher Charlson Co-morbidity index scores (P: <0.01), and 77.8% of those who had PAL >7 days were considered unfit for surgery. Of these, pneumothorax had not recurred in 69.4% after two years (HR: 0.47; P: 0.044). Conclusion Bulla was positively associated with PAL over seven days in SSP patients while albumin was negatively associated. PAL over seven days increased future recurrent pneumothorax risks, while elderly SSP patients unfit for surgery had acceptable recurrence rates after medical pleurodesis.

Abstract
During thoracic operations, surgical staplers resect cancerous tumors and seal the spared lung. However, post-operative air leaks are undesirable clinical consequences: staple legs wound lung tissue. Subsequent to this trauma, air leaks from lung tissue into the pleural space. This affects the lung's physiology and patients' recovery. The objective is to biomechanically and visually characterize porcine lung tissue with and without staples in order to gain knowledge on air leakage following pulmonary resection. Therefore, a syringe pump filled with air inflates and deflates eleven porcine lungs cyclically without exceeding 10 cmH2O of pressure. Cameras capture stereo-images of the deformed lung surface at regular intervals while a microcontroller simultaneously records the alveolar pressure and the volume of air pumped. The raw images are then used to compute tri-dimensional displacements and strains with the Digital Image Correlation method (DIC). Air bubbles originated at staple holes of inner row from exposed porcine lung tissue due to torn pleural on costal surface. Compared during inflation, left upper or lower lobe resections have similar compliance (slope of the pressure vs volume curve), which are 9% lower than healthy lung compliance. However, lower lobes statistically burst at lower pressures than upper lobes (p-value<0.046) in ex vivo conditions confirming previous clinical in vivo studies. In parallel, the lung deformed mostly in the vicinity of staple holes and presented maximum shear strain near the observed leak location. To conclude, a novel technique DIC provided concrete evidence of the post-operative air leaks biomechanics. Further studies could investigate causal relationships between the mechanical parameters and the development of an air leak.

Abstract
Persistent air leak (PAL) is a challenging clinical entity, particularly in the setting of critical illness. It is a significant cause of morbidity, health care expenditure, and resource utilization. Data on its prevalence in the critically ill patient population are limited. Unique patient factors often necessitate an individualized approach. Guidelines on this subject are antiquated and do not specially address patients on mechanical ventilation. Critically ill patients may not be able to tolerate surgical intervention. Treatment in this population relies upon lung protective ventilation, various anecdotal modalities, chemical pleurodesis, autologous blood patching, and bronchoscopic insertion of endobronchial valves. Ventilation strategies center on rapid weaning and reduction of airway pressures. Anecdotal methods include implantable devices and chemical agents. Data on these modalities are limited to case reports. None have United States Food and Drug Administration (FDA) approval. The Spiration Valve System is FDA approved as a Humanitarian Device Exemption. Data on endobronchial valves are based on large case series, and only one small case series has focused exclusively on critically ill patients. The majority of valves in critically ill mechanically ventilated patients are used for non-FDA approved indications. Updated guidelines are desperately needed to ensure a standardized approach to this common clinical situation.

Abstract
OBJECTIVE In this study, we introduce a novel approach, thoracoscopic transareolar bullectomy, for treating young male patients with primary spontaneous pneumothorax (PSP). This approach might be less invasive and cosmetically superior to existing methods. We also prospectively compared transareolar and uniportal approaches. METHODS Between April 2018 and July 2019, 40 patients were prospectively assigned to transareolar (n = 21) and uniportal (n = 19) groups. We compared patient characteristics and perioperative results. Approximately 1 week or 1 year after the operation, postoperative pain was evaluated using a numerical rating scale (NRS), and cosmetic satisfaction was graded on a four-point scale. RESULTS We found no significant between-group differences in patient characteristics or perioperative results. NRS scores did not differ on postoperative day (POD) 7 (transareolar, 1.8 ± 0.9 vs. uniportal, 1.6 ± 0.9; p = 0.62) or in postoperative month (POM) 12 (transareolar, 1.3 ± 0.5 vs. uniportal, 1.1 ± 0.5; p = 0.18). In terms of cosmetic satisfaction, the transareolar group was more satisfied on POD 7 (transareolar, 3.5 ± 0.6 vs. uniportal, 2.9 ± 0.9; p = 0.02) and in POM 12 (transareolar, 3.8 ± 0.5 vs. uniportal, 3.3 ± 0.9; p = 0.0065). CONCLUSION Although the perioperative results of the transareolar and uniportal approaches were similar, the former approach afforded a little better cosmetic satisfaction and might be useful option for young males with PSP.

Abstract
BACKGROUND There is limited information on the frequency of complications among older adults after oncological thoracic surgery in the modern era. We hypothesized that morbidity and mortality in older adults with lung cancer undergoing lobectomy is low and different than that of younger patients undergoing thoracic surgery. METHODS All patients undergoing lobectomy at a large volume academic center between May 2016 and May 2019 were included. Patients were prospectively monitored to grade postoperative morbidity by organ system, based on the Clavien-Dindo classification. Patients were divided into two groups: Group 1 included patients 65-91 years of age, and Group 2 included those <65 years. RESULTS Of 680 lobectomies in 673 patients, 414(61%) were older than 65 years of age (group 1). Median age at surgery was 68 years (20-91). Median hospital stay was 4 days (1-38) and longer in older adults. Older adults experienced higher rates of grade II and IV complications, mostly driven by an increased incidence of delirium, atrial fibrillation, prolonged air leak, respiratory failure and urinary retention. In this modern cohort, there was only 1 stroke (0.1%), and delirium was reduced to 7%. Patients undergoing minimally invasive (MI) surgery had a lower rate of Grade IV life-threatening complications. Older adults were more likely to be discharged to a rehabilitation facility, however this difference also disappeared with MI surgical procedures. CONCLUSIONS Current morbidity of older adults undergoing lobectomy for cancer is low and is different than that of younger patients. Thoracotomy may be associated with postoperative complications in these patients. Our findings suggest the need to consider MI approaches and broad-based, geriatric-focused perioperative management of older adults undergoing lobectomy.

Abstract
Prolonged air leak or alveolar-pleural fistula is common after lung resection and can usually be managed with continued pleural drainage until resolution. Further management options include blood patch administration, chemical pleurodesis, and 1-way endobronchial valve placement. Bronchopleural fistula is rare but is associated with high mortality, often caused by development of concomitant empyema. Bronchopleural fistula should be confirmed with bronchoscopy, which may allow bronchoscopic intervention; however, transthoracic stump revision or window thoracostomy may be required.

Abstract
Background The treatment of primary spontaneous pneumothorax (PSP) remains controversial. Guidelines do not explicitly define surgical procedures. Different treatment modalities are observed in clinics of same profile. Treatment is controversial. The aim of the work was to compare the effectiveness of two methods-pleurectomy and pleurectomy combined with wedge resection in patients with PSP in terms of safety and efficiency. Methods Non-randomized observational study based on clinical analysis of 73 patients, M:F ratio 3:1, aged 18 to 45 years, the average age was 29 years, operated between January 2008 and December 2014 due to the occurrence of PSP. Pleurectomy was supplemented by wedge resection in patients diagnosed intraoperatively with ELC (emphsema-like changes) ≥ III stage (classification of PSP by Vanderschueren). Efficacy was defined as follows: complete lung expansion, drainage (days), air leak, frequency of PAL (persistent air leak >5 days), recurrences and re-operations. Safety was defined as follows: heamothorax, major bleeding (loss of Hg >2 g/dL), infections, deaths. The research project was approved by the Bioethical Commission of the Silesian Medical University in Katowice (KNW/022/kb1/3/14). Results Mean follow-up was 22 months. Efficacy: recurrences occurred less frequently in group treated with pleurectomy without wedge resection. No results were found in other parameters. Safety: No results were found in all parameters. Conclusions Efficacy and safety of pleurectomy vs. pleurectomy + wedge resection is comparable.

Abstract
Aim In this study, we aimed to retrospectively investigate whether pectus excavatum (PE) is a risk factor for the development of primary spontaneous pneumothorax (PSP) and to determine its role in the etiology of the disease. Materials and Methods Chest-computed tomography (CT) of the patients who were treated for spontaneous pneumothorax between January 2015 and December 2017 in our clinic was examined, and their Haller indices were measured (group I). The patients in the control group who underwent chest CT for other reasons during the same period and were in the same age with the group I were also included in the study (group II) Results. In group I, for patients with PE, the mean Haller index was 2.41, while it was 2.09 in the control group (group II). There was a significant difference between the two groups. Conclusions PE deformities in the chest wall may predispose to the development of spontaneous pneumothorax, and PE may be among the etiologic factors of spontaneous pneumothorax. Therefore, there is a need for studies involving larger patient groups.

Abstract
Alveolar-pleural fistulas causing persistent air leaks (PALs) are associated with prolonged hospital stays and high morbidity. Prior guidelines recommend surgical repair as the gold standard for treatment, albeit it is a solution with limited success. In patients who have recently undergone thoracic surgery or in whom surgery would be contraindicated based on the severity of illness, there has been a lack of treatment options. This review describes a brief history of treatment guidelines for PALs. In the past 20 years, newer and less invasive treatment options have been developed. Aside from supportive care, the literature includes anecdotal successful reports using fibrin sealants, ethanol injection, metal coils, and Watanabe spigots. More recently, larger studies have demonstrated success with chemical pleurodesis, autologous blood patch pleurodesis, and endobronchial valves. This manuscript describes these treatment options in detail, including postprocedural adverse events. Further research, including randomized controlled trials with comparison of these options, are needed, as is long-term follow-up for these interventions.

Abstract
INTRODUCTION Deteriorated alveolar structure at the base of blebs and bullae is known as the reticulated trabecula-like structure. Its clinical significance in primary spontaneous pneumothorax (PSP) remains unclear. This study aimed to investigate the impact of the structure on recurrence of PSP after video-assisted thoracoscopic surgery (VATS) bullectomy. METHODS Between April 2010 and March 2014, 80 cases of PSP in 76 patients who underwent VATS bullectomy using endoscopic staplers were included. The staple line was covered with polyglycolic acid sheets and fibrin glue. Cases were assigned to a normal alveolar structure (NAS) group (n = 54) and a reticulated trabecula-like structure (RT) group (n = 26) based on the histological analysis. Factors associated with recurrence were analysed using logistic regression. RESULTS The reticulated trabecula-like structure was significantly related to apical lung blebs. The recurrence rate of PSP was significantly higher in the RT group than in the NAS group (38.5% vs. 3.7%; P <0.001). On multivariate analysis, the reticulated trabecula-like structure was an independent factor for recurrence of PSP after VATS bullectomy. CONCLUSION The change of alveolar structure at the base of apical lung blebs would increase the risk for recurrence of PSP after VATS bullectomy.

Abstract
OBJECTIVES There are no guidelines regarding the surgical approach for spontaneous pneumothorax. It has been reported, however, that the risk of recurrence following video-assisted thoracic surgery is higher than that following open thoracotomy (OT). The objective of this study was to determine whether this higher risk of recurrence following video-assisted thoracic surgery could be attributable to differences in intraoperative parenchymal resection and the pleurodesis technique. METHODS Data for 7647 patients operated on for primary or secondary spontaneous pneumothorax between 1 January 2005 and 31 December 2012 were extracted from Epithor®, the French national database. The type of pleurodesis and parenchymal resection was collected. Outcomes were (i) bleeding, defined as postoperative pleural bleeding; (ii) pulmonary and pleural complications, defined as atelectasis, pneumonia, empyema, prolonged ventilation, acute respiratory distress syndrome and prolonged air leaks; (iii) in-hospital length of stay and (iv) recurrence, defined as chest drainage or surgery for a second pneumothorax. RESULTS Of note, 6643 patients underwent videothoracoscopy and 1004 patients underwent OT. When compared with the thoracotomy group, the videothoracoscopy group was associated with more parenchymal resections (62.4 vs 80%, P = 0.01), fewer mechanical pleurodesis procedures (93 vs 77.5%, P < 10(-3)), fewer postoperative respiratory complications (12 vs 8.2%, P = 0.01), fewer cases of postoperative pleural bleeding (2.3 vs 1.4%, P = 0.04) and shorter hospital lengths of stay (16 vs 9 days, P = 0.01). The recurrence rate was 1.8% (n = 18) in the thoracotomy group versus 3.8% (n = 254) in the videothoracoscopy group (P = 0.01). The median time between surgery and recurrence was 3 months (range: 1-76 months). CONCLUSIONS In the surgical management of spontaneous pneumothorax, videothoracoscopy is associated with a higher rate of recurrence than OT. This difference might be attributable to differences in the pleurodesis technique rather than differences in the parenchymal resection.

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