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
The Society of Thoracic Surgeons Workforce on Evidence-Based Surgery provides this document on management of pleural drains after pulmonary lobectomy. The goal of this consensus document is to provide guidance regarding pleural drains in 5 specific areas: (1) choice of drain, including size, type, and number; (2) management, including use of suction vs water seal and criteria for removal; (3) imaging recommendations, including the use of daily and postpull chest roentgenograms; (4) use of digital drainage systems; and (5) management of prolonged air leak. To formulate the consensus statements, a task force of 15 general thoracic surgeons was invited to review the existing literature on this topic. Consensus was obtained using a modified Delphi method consisting of 2 rounds of voting until 75% agreement on the statements was reached. A total of 13 consensus statements are provided to encourage standardization and stimulate additional research in this important area.

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.

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 Uniportal video-assisted thoracoscopic surgery (UniVATS) was utilized with a rapid growth. The evidence is sparse, however, on whether to add external suction to water-seal drainage for chest drainage after UniVATS. This retrospective propensity score-matched study aimed to identify the necessity of adding external suction to chest drainage after UniVATS. Methods Patients with lung cancer who underwent UniVATS were included from our prospectively maintained database. Patients were divided into two cohorts based on the addition of external suction to postoperative water-seal drainage or not. Propensity score-matched analysis was performed to identify the impact of suction on chest tube duration, incidence of persistent air leak, hospital stay, and hospitalization cost. Multivariable model with interaction terms was constructed to identify impact of covariables on effect of suction. Results The two cohorts matched well on baseline characteristics (nonsuction: 173; suction: 96). Compared with nonsuction group, suction group showed longer median chest tube duration (3 vs. 2 days, p = 0.003), higher incidences of persistent air leak (9.4% vs. 1.2%, p = 0.003), persistent drainage (16.8% vs. 5.8%, p = 0.007), and reduced drainage volume within first 3 postoperative days (386.90 vs. 504.78 ml, p = 0.011). Resection extent was identified to mediate the relationship between suction and chest tube drainage. Conclusions These findings discouraged adding external suction to water-seal drainage after UniVATS regarding longer chest tube duration and more persistent air leak. Patients undergoing lobectomy would benefit more from water-seal drainage without external suction compared with those doing sublobectomy.

Abstract
OBJECTIVE To describe the physiology of air leak in bronchopleural fistula in mechanically ventilated patients and how understanding of its physiology drives management of positive-pressure ventilation. To provide guidance of lung isolation, mechanical ventilator, pleural catheter, and endobronchial strategies for the management of bronchopleural fistula on mechanical ventilation. DATA SOURCES Online search of PubMed and manual review of articles (laboratory and patient studies) was performed. STUDY SELECTION Articles relevant to bronchopleural fistula, mechanical ventilation in patients with bronchopleural fistula, independent lung ventilation, high-flow ventilatory modes, physiology of persistent air leak, extracorporeal membrane oxygenation, fluid dynamics of bronchopleural fistula airflow, and intrapleural catheter management were selected. Randomized trials, observational studies, case reports, and physiologic studies were included. DATA EXTRACTION Data from selected studies were qualitatively evaluated for this review. We included data illustrating the physiology of driving pressure across a bronchopleural fistula as well as data, largely from case reports, demonstrating management and outcomes with various ventilator modes, intrapleural catheter techniques, endoscopic placement of occlusion and valve devices, and extracorporeal membrane oxygenation. Themes related to managing persistent air leak with mechanical ventilation were reviewed and extracted. DATA SYNTHESIS In case reports that demonstrate different approaches to managing patients with bronchopleural fistula requiring mechanical ventilation, common themes emerge. Strategies aimed at decreasing peak inspiratory pressure, using lower tidal volumes, lowering positive end-expiratory pressure, decreasing the inspiratory time, and decreasing the respiratory rate, while minimizing negative intrapleural pressure decreases airflow across the bronchopleural fistula. CONCLUSIONS Mechanical ventilation and intrapleural catheter management must be individualized and aimed at reducing air leak. Clinicians should emphasize reducing peak inspiratory pressures, reducing positive end-expiratory pressure, and limiting negative intrapleural pressure. In refractory cases, clinicians can consider lung isolation, independent lung ventilation, or extracorporeal membrane oxygenation in appropriate patients as well as definitive management with advanced bronchoscopic placement of valves or occlusion devices.

Abstract
Cystic fibrosis (CF) is an autosomal recessive genetic condition with multisystemic disease manifestations, the most prominent of which occur in the respiratory system. Despite significant developments in disease understanding and therapeutics, each contributing to improved lung function and survival in patients with CF, several pulmonary complications, including pneumothorax, massive hemoptysis, and respiratory failure, continue to occur. In this review, we briefly describe each of these complications and their management and discuss how they impact the care and disease trajectory of individuals in whom they occur. Finally, we discuss the evolving role that palliative care and CF transmembrane conductance regular modulator therapies play in the natural disease course and care of patients with CF.

Abstract
Background A prolonged air leak (PAL) is the most frequent complication after pulmonary resection. This study aimed to assess the safety and efficacy of autologous blood patch pleurodesis (ABPP) to treat PAL. Methods A prospectively maintained database identified patients with a PAL after pulmonary resection for lung cancer between 2015–2019. In this observational cohort study, clinical data were collected to retrospectively compare patients undergoing ABPP to no ABPP in a propensity-matched analysis. Kaplan Meier estimates and Cox models accounting for inverse probability weighting (IPTW) were used to assess the association of ABPP with each outcome. Results Of the 740 patients undergoing lung resection, 110 (15%) were identified as having a PAL at postoperative day (POD) 5. There was no difference between baseline characteristics among those undergoing ABPP (n=34) versus no ABPP (n=76). Propensity-weighted analysis did not reveal a significant association of ABPP treatment with in-hospital complication (P=0.18), hospital length of stay (LOS) (P=0.13), or post-discharge complication (P=0.13). However, ABPP treatment was associated with a lower risk of hospital readmission [P=0.02, hazard ratio (HR) 0.16] and reoperation for air leak or empyema (P=0.05, HR 0.11). Although not statistically significant, the mean chest tube (CT) removal of 11 days for the ABPP group was less than the no ABPP group (16 days) (P=0.14, HR 1.5–2). Those treated with ABPP were less likely to be discharged with a CT (ABPP 7/34, 21% vs. no ABPP 40/76, 53%). There was no statistical difference in empyema development between groups (ABPP 0/34, 0% vs. no ABPP 4/76, 5%, P=0.39, HR 0.24). Conclusions ABPP administration is safe compared to traditional PAL management. In a retrospective propensity-matched analysis, postoperative patients treated with ABPP required less readmission and reoperation for PAL. Larger powered randomized trials may demonstrate the magnitude of benefit from treatment with ABPP.

Abstract
PURPOSE While surgery is an effective treatment for secondary spontaneous pneumothorax (SSP), it can be difficult, because affected patients are usually in a poor general condition. The present study investigated the risk factors of postoperative complications after surgery for SSP. METHODS Eighty-eight patients with SSP who underwent surgery from January 2006 to March 2018 were investigated. Clinical data were reviewed, and a multivariate analysis was performed. RESULTS Eighty-four patients (95%) were males, and the median patient age was 72 years. Underlying lung diseases were chronic obstructive pulmonary disease in 58 patients (65.9%), interstitial pneumonia in 26 (29.5%), and others in 4 (4.5%). Postoperative complications developed in 21 patients (24%). Hospital mortality/prolonged length of stay occurred in 6 patients (7%). A multivariate analysis showed that the preoperative performance status (performance status 0-2 vs. 3, hazard ratio: 6.570, 95% confidence interval: 1.980-21.800) was an independent predictor of postoperative complications. CONCLUSION Surgery for SSP contributed to early chest tube removal and favorable outcomes. However, rare fatal events occurred, and the patient performance status was a risk factor for postoperative complications. A careful evaluation of each patient's performance status is needed to determine the need for surgical intervention for SSP.

Abstract
Persistent air leak (PAL) is a common problem after secondary pneumothorax due to cystic fibrosis (CF). These leaks, caused by either bronchopleural or alveolopleural fistula, are associated with higher morbidity and mortality [1]. Air leaks are traditionally treated with chronic chest tube drainage, chemical pleurodesis, or autologous blood patching in non-surgical candidates [1]. However, these strategies can increase infectious risk or pleural scarring, which are associated with poorer lung transplant surgical outcomes. Endobronchial valve (EBV) placement, while FDA-approved for use in both some surgical PALs and bronchoscopic volume reduction therapy, is one alternative option, but it could theoretically increase the risk of infection, especially in CF patients. Here, we report the case of a CF patient under evaluation for lung transplant who received EBVs for PAL after bilateral secondary spontaneous pneumothoraces.

Abstract
PURPOSE Air leaks are common after lobectomy, segmentectomy, and lung volume reduction surgery (LVRS). This can increase post-operative morbidity, cost, and hospital length of stay. The management of post-pulmonary resection air leaks remains challenging. Minimally invasive effective interventions are necessary. The Spiration Valve System (SVS, Olympus/Spiration Inc., Redmond, WA, US) is approved by the FDA under humanitarian use exemption for management of prolonged air leaks. METHODS This is a prospective multicenter registry of 39 patients with air leaks after lobectomy, segmentectomy, and LVRS managed with an intention to use bronchoscopic SVS to resolve air leaks. RESULTS Bronchoscopic SVS placement was feasible in 82.1% of patients (32/39 patients) and 90 valves were placed with a median of 2 valves per patient (mean of 2.7 ± 1.5 valves, range of 1 to 7 valves). Positive response to SVS placement was documented in 76.9% of all patients (30/39 patients) and in 93.8% of patients when SVS placement was feasible (30/32 patients). Air leaks ultimately resolved when SVS placement was feasible in 87.5% of patients (28/32 patients), after a median of 2.5 days (mean ± SD of 8.9 ± 12.4 days). Considering all patients with an intention to treat analysis, bronchoscopic SVS procedure likely contributed to resolution of air leaks in 71.8% of patients (28/39 patients). The post-procedure median hospital stay was 4 days (mean 6.0 ± 6.1 days). CONCLUSIONS This prospective registry adds to the growing body of literature supporting feasible and effective management of air leaks utilizing one-way valves.

Abstract
Airleaks are one of the most common complications associated with elective lung resection. There have been many techniques and modern advancements in thoracic surgery, however airleaks persist. This review article will discuss several interventions ranging from conservative noninvasive to surgical management of the persistent airleak. These techniques include stopping of suction on the plueravac, fibrin patches, pleurodesis, use of endobronchial valves (EBVs), return to OR for operative intervention, and lastly to send patients home with mini pleuravacs.

Abstract
Background To evaluate the efficacy of Endo-Bronchial Valves in the management of persistent air-leaks (PALs) and the procedural cost. Methods It was a retrospective multicenter study including consecutive patients with PALs for alveolar pleural fistula (APF) undergoing valve treatment. We assessed the efficacy and the cost of the procedure. Results Seventy-four patients with persistent air leaks due to various etiologies were included in the analysis. In all cases the air leaks were severe and refractory to standard treatments. Sixty-seven (91%) patients underwent valve treatment obtaining a complete resolution of air-leaks in 59 (88%) patients; a reduction of air-leaks in 6 (9%); and no benefits in 2 (3%). The comparison of data before and after valve treatment showed a significant reduction of air-leak duration (16.2±8.8 versus 5.0±1.7 days; P<0.0001); chest tube removal (16.2±8.8 versus 7.3±2.7 days; P<0.0001); and length of hospital stay (LOS) (16.2±8.8 versus 9.7±2.8 days; P=0.004). Seven patients not undergoing valve treatment underwent pneumo-peritoneum with pleurodesis (n=6) or only pleurodesis (n=1). In only 1 (14%) patient, the chest drainage was removed 23 days later while the remaining 6 (86%) were discharged with a domiciliary chest drainage removed after 157±41 days. No significant difference was found in health cost before and after endobronchial valve (EBV) implant (P=0.3). Conclusions Valve treatment for persistent air leaks is an effective procedure. The reduction of hospitalization costs related to early resolution of air-leaks could overcome the procedural cost.

Abstract
Introduction Bronchopleural fistula (BPF) is a feared complication of pulmonary resection. Fistula plugs (FP) have been described as an adequate treatment in anorectal disease. We describe our early experience placing an FP in the treatment of BPF. Materials and methods We retrospectively reviewed 5 patients for whom a FP was placed for BPF at our institution. Demographic data, initial perioperative information, method and technique of FP placement, and success is reported. Results Five patients (4 male, 1 female) with a median age of 63 years (range, 57–76 years) underwent 6 FP placements for BPF. Two patients were post-pneumonectomy and 3 patients post-lobectomy. The median time to presentation following surgery was 118 days (range 22–218). Upon bronchoscopic or operative re-evaluation, 3 patients had successful cessation of their air leak at 0, 1 and 4 days. Two of three patients subsequently underwent a thoracic muscle flap placement to augment healing. One patient had a persistent air leak despite 2 separate FP placements. The air leak stopped with endobronchial valves (EBV) which were deployed proximal to the FP, 9 days after placement of the FP. Another patient had a successful muscle flap placed 80 days after FP placement. There were no complications associated with the FP. Three of five patients were deemed successfully treated with FP placement alone. Conclusion In patients with a postoperative BPF and pleural window, placement of a FP had a modest success rate and can be considered as a treatment modality option for BPF.

Abstract
Since pulmonary pathologies, such as lung cancer and chronic obstructive pulmonary disease (COPD), are some of the leading causes of morbidity and mortality around the world, pulmonologists are likely to encounter patients with unmet palliative care needs. This article focuses on the symptoms and complications encountered by patients with terminal pulmonary conditions, briefly describes the non-interventional palliative strategies, and then discusses more advanced therapies available in the realm of interventional pulmonology. Most of the literature discussed here is derived from patients with lung cancer and COPD.

Abstract
Persistent air leak (PAL) is associated with significant morbidity and mortality, prolonged hospitalization and increased health-care costs. It can arise from a number of conditions, including pneumothorax, necrotizing infection, trauma, malignancies, procedural interventions and complications after thoracic surgery. Numerous therapeutic options, including noninvasive and invasive techniques, are available to treat PALs. Recently, endobronchial one-way valves have been used to treat PAL. We conducted a systematic review based on studies retrieved from PubMed, EMbase and Cochrane library. We also did a hand-search in the bibliographies of relevant articles for additional studies. 34 case reports and 10 case series comprising 208 patients were included in our review. Only 4 patients were children, most of the patients were males. The most common underlying disease was COPD, emphysema and cancer. The most remarkable cause was pneumothorax. The upper lobes were the most frequent locations of air leaks. Complete resolution was gained within less than 24 h in majority of patients. Complications were migration or expectoration of valves, moderate oxygen desaturation and infection of related lung. No death related to endobronchial one-way valves implantation has been found. The use of endobronchial one-way valve adds to the armamentarium for non-invasive treatments of challenging PAL, especially those with difficulties of anesthesia, poor condition and high morbidity. Nevertheless, prospective randomized control trials with large sample should be needed to further evaluate the effects and safety of endobronchial one-way valve implantation in the treatment of PAL.

Abstract
Background: Prolonged pulmonary air leaks (PALs) are associated with increased morbidity and extended hospital stay. We sought to investigate the role of bronchoscopic placement of 1-way valves in treating this condition. Methods: We queried a prospectively maintained database of patients with PAL lasting more than 7 days at a tertiary medical center. Main outcome measures included duration of chest tube placement and hospital stay before and after valve deployment. Results: Sixteen patients were eligible to be enrolled from September 2012 through December 2014. One patient refused to give consent, and in 4 patients, the source of air leak could not be identified with bronchoscopic balloon occlusion. Eleven patients (9 men; mean age, 65 ± 15 years) underwent bronchoscopic valve deployment. Eight patients had postoperative PAL and 3 had a secondary spontaneous pneumothorax. The mean duration of air leak before valve deployment was 16 ± 12 days, and the mean number of implanted valves was 1.9 (median, 2). Mean duration of hospital stay before and after valve deployment was 18 and 9 days, respectively (P = .03). Patients who had more than a 50% decrease in air leak on digital monitoring had the thoracostomy tube removed within 3–6 days. There were no procedural complications related to deployment or removal of the valves. Conclusions: Bronchoscopic placement of 1-way valves is a safe procedure that could help manage patients with prolonged PAL. A prospective randomized trial with cost-efficiency analysis is necessary to better define the role of this bronchoscopic intervention and demonstrate its effect on air leak duration.

Abstract
AIM to improve treatment of patients with spontaneous pneumothorax who had not postoperative pulmonary impermeability. MATERIAL AND METHODS 87 patients with spontaneous pneumothorax underwent videothoracoscopy (VTS), lung resection supplemented by pleurodesis (parietal pleurectomy or pleural abrasion). Absence of pulmonary impermeability was observed in 5 (5.7%) patients. RESULTS AND DISCUSSION Re-operation was performed in 2 patients (Vanderschuren 2 and 3) namely re-thoracoscopy and thoracotomy with additional ligation of air origins. Drainage tubes were removed in 4 and 17 days postoperatively in patient without/with emphysema respectively. In patient (Vanderschuren 1) who underwent thoracoscopic resection and parietal pleural abrasion valve bronchoblocation was performed in 9 days after VTS due to persistent pneumothorax. Pleural drainage tube was removed in 13 days (emphysema) after bronchial valve deployment. 2 patients (Vanderschuren 4) had heterogeneous pulmonary emphysema. One of them underwent video-assisted mini-thoracotomy, lung resection with reinforcement of seams with synthetic material. In other observation conversion to thoracotomy followed by atypical resection of bullous emphysema and manual suturing of lung was applied. In both cases bronchoblocation was performed intraoperatively with good results. Drainage tubes were removed in 13 and 17 days respectively. There were no complications. CONCLUSION Intraoperative endoscopic bronchoblocation is advisable if air leakage is considerable in operating theater and complicates lung smoothing. Such approach reduces hospital-stay and improves outcomes.
