RESUMO
INTRODUCTION: The use of non-steroidal anti-inflammatory drugs (NSAID) in patients undergoing pleurodesis remains controversial. Although many surgeons are comfortable prescribing NSAIDs post-operatively, some oppose this practice due to concerns of suppressing the inflammatory response and quality of pleurodesis. Only a small body of inconsistent publications exists with respect to guiding therapy in this common clinical scenario. METHODS: A retrospective cohort study was undertaken assessing effect of NSAID exposure on pleurodesis outcomes. An institutional thoracic surgery database was reviewed yielding 147 patients who underwent pleurodesis for pneumothorax between 2010 and 2018. Medical records and imaging were reviewed for patient characteristics, NSAID exposure, recurrent pneumothorax and other adverse events. RESULTS: There was no overall difference between rates of recurrence and procedural failure of pleurodesis (Relative Risk [RR] 1.67 [95% CI 0.74-3.77]). However, NSAID exposure of >48 hours was associated with increased risk of recurrent pneumothorax (RR 2.16 [95% CI 1.05-4.45]). There was no increased rate of other adverse events related to NSAID usage. CONCLUSIONS: NSAID exposure does not increase failure rates or other adverse events following pleurodesis for pneumothorax. However, prolonged NSAID exposure post-pleurodesis may increase procedural failure rates. Further large volume randomised control trials are required.

BACKGROUND: The prolonged air leak is probably the most common complication following lung resections. Around 10-20% of the patients who undergo a lung resection will eventually develop a prolonged air leak. The definition of a prolonged air leak varies between an air leak, which is evident after the fifth, seventh or even tenth postoperative day to every air leak that prolongs the hospital stay. However, the postoperative hospital stay following a thoracoscopic lobectomy can be as short as 2 days, making the above definitions sound outdated. The treatment of these air leaks is also very versatile. One of the broadly accepted treatment options is the autologous blood pleurodesis or "blood patch". The purpose of this trial is to investigate the impact of a prophylactic autologous blood pleurodesis on reducing the duration of the postoperative air leak and therefore prevent the air leak from becoming prolonged. METHODS: Patients undergoing an elective thoracoscopic anatomic lung resection for primary lung cancer or metastatic disease will be eligible for recruitment. Patients with an air leak of > 100 ml/min within 6 h prior to the morning round on the second postoperative day will be eligible for inclusion in the study and randomization. Patients will be randomized to either blood pleurodesis or watchful waiting. The primary endpoint is the time to drain removal measured in full days. The trial ends on the seventh postoperative day. DISCUSSION: The early autologous blood pleurodesis could lead to a faster cessation of the air leak and therefore to a faster removal of the drain. A faster removal of the drain would relieve the patient from all the well-known drain-associated complications (longer hospital stay, stronger postoperative pain, risk of drain-associated infection, etc.). From the economical point of view, faster drain removal would reduce the hospital costs as well as the costs associated with the care of a patient with a chest drain in an outpatient setting.

PURPOSE: A prolonged air leak (PAL) is one of the common postoperative complications of pulmonary resection. The aim of this study was to evaluate the efficacy and safety of pleurodesis with sterile talc or OK-432 for postoperative air leak. METHODS: Patients with postoperative air leak who received chemical pleurodesis using sterile talc or OK-432 were retrospectively identified from medical records data. For pleurodesis with either agent, prior assessment and approval by the hospital safety department were carried out for each case, in addition to individual consent. RESULTS: Between February 2016 and June 2022, 39 patients had PALs and underwent chemical pleurodesis. Among them, 24 patients received pleurodesis with talc (Talc group) and 15 with OK-432 (OK-432 group). The leak resolved after less than two pleurodesis treatments in 22 patients (91.7%) in the Talc group compared with 14 patients (93.3%) in the OK-432 group. Pleurodesis significantly increased white blood cell counts, C-reactive protein concentration, and body temperature in the OK-432 group compared with that in the Talc group (p <0.001, p = 0.003, and p <0.001, respectively). CONCLUSIONS: Pleurodesis with talc may be an effective treatment option for postoperative air leak. Our findings suggest that talc was as effective as OK-432 and resulted in a milder systemic inflammatory response.

Malignant pleural effusion (MPE) is a pleural effusion that is caused by a malignant tumor originating in the pleura or by a metastatic malignant tumor from another site that has invaded the pleura. MPE is associated with poor prognosis. Members of the Pleural and Mediastinal Diseases Working Group (preparatory) of Chinese Thoracic Society and some external experts selected clinical issues related to the management of MPE and conducted rigorous evidence retrieval and evaluation. After several meetings and revisions of the manuscript, recommendations were made. This consensus applies to patients aged≥18 years old with MPE caused by various malignancies except for pleural mesothelioma. It included four chapters: pathogenesis of MPE, prognostic evaluation of MPE, local thoracic treatment, and systemic anticancer therapy for MPE.The main recommendations of this consensus are as follows:1. Prognosis evaluation of MPE was valuable in formulating treatment options. It is suggested to comprehensively evaluate the patient's prognosis by combining the patient's performance status, tumor type, and laboratory examination.2. It is recommended that in patients with symptomatic MPE, therapeutic thoracentesis could be used as the initial therapeutic option. Evaluate whether the lung is expandable after thoracentesis and drainage, and then develop a therapeutic regimen.3. In patients with MPE and known expandable or nonexpandable lung, an indwelling pleural catheter (IPC) is recommended as a first-line pleural management. Daily IPC drainages are recommended. In patients with MPE and expandable lung, talc pleurodesis by talc poudrage or talc slurry is recommended if the drug is accessible. Other pleurodesis agents include povidone iodine, bleomycin, and doxycycline.4. After drainage, it is suggested to consider the option of intrapleural use of recombinant human endostatin or bevacizumab alone or in combination with intrapleural chemotherapy. Intrapleural intervention including electrocautery, argon knife, cryotherapy, laser and radiofrequency ablation, is recommended for use in patients who have undergone rigorous evaluation in eligible hospitals. The use of intrapleural urokinase or streptokinase via pleural catheter is recommended for patients with symptomatic MPE and loculated effusion.5. For patients with good performance status and metastatic malignancies, systemic anti-cancer treatment is recommended as standard of care.

Chylothorax is a rare condition caused by pleural effusion resulting from thoracic duct injury. Recurrent chylothorax is often resistant to conservative treatment and presents a clinical conundrum in its management. Here, we report a compelling case of recurrent chylothorax that persisted despite the administration of total parenteral nutrition, octreotide and thoracic duct embolisation. The patient eventually required thoracic duct ligation and talc pleurodesis, which resulted in the resolution of the effusion. Our case is an illustrative example of the effective multidisciplinary management of recurrent bilateral idiopathic chylothorax.

Spontaneous pneumothorax is a classical medical condition encountered in emergency centers, and by primary care and respiratory physicians. The traditional distinction between primary and secondary pneumothorax, although old and increasingly blurred, still allows to guide initial management and to determine whether pleurodesis is indicated. In case of spontaneous pneumothorax, a targeted family history is essential because it can suggest the presence of a genetic syndrome as the underlying cause of the pneumothorax, a condition often associated with a high risk of pneumothorax recurrence, and the occurrence of extrathoracic manifestations which may be serious if recognized late. This review addresses the classification of spontaneous pneumothorax, its pathogenesis, the risk factors of occurrence including genetic syndromes, and its management.
Le pneumothorax spontané constitue une situation médicale classique rencontrée dans les centres d'urgence, chez le médecin de premier recours et le pneumologue. La traditionnelle distinction entre pneumothorax primaire et secondaire, bien qu'ancienne et de plus en plus incertaine, permet encore de diriger la prise en charge initiale et de décider si une pleurodèse est indiquée. En cas de pneumothorax spontané, une anamnèse familiale ciblée est primordiale car elle peut suggérer la présence d'un syndrome génétique à l'origine du pneumothorax, souvent associé à un risque élevé de récidive et à la survenue de manifestations extrathoraciques qui peuvent être graves si diagnostiquées tardivement. Cet article aborde la classification du pneumo thorax spontané, sa patho genèse, ses facteurs de risque y compris génétiques, et sa prise en charge.

BACKGROUND AND AIMS: Thoracic air leak syndrome (TALS) is a complication related to chronic pulmonary graft-versus-host disease (pGvHD) that affects approximately 0.83%-3.08% patients after allogenic hematopoietic stem cell transplant. Such complication is defined as the occurrence of any form of air leak in the thorax, including spontaneous pneumomediastinum or pneumopericardium, subcutaneous emphysema, interstitial emphysema and pneumothorax and has a negative impact on post-transplant survival. The aim of the present study is to describe a single-center experience in the surgical management of recurrent TALS in adolescents and young adults and its outcome. METHODS: We retrospectively reviewed the clinical notes of patients with previous allogenic hematopoietic stem cell transplant who underwent surgical procedures for recurrent TALS from January 2016 until March 2021. We analyzed clinical data, number of episodes of thoracic air leak, surgical procedures and relative outcome. RESULTS: In the examined period, four patients, aged 16-25 years, underwent surgical procedures for TALS, including thoracostomy tube placement, thoracoscopic pleurodesis and thoracotomy. All the patients had been diagnosed with pGvHD before the onset of TALS, with a mean time lapse of 276 days (range 42-513). These patients experienced on average 4.5 air leak episodes (range 3-6). All the patients experienced at least two episodes before surgery. One patient underwent emergency tube thoracostomy only, three patients underwent thoracoscopic pleurodesis and two patients underwent thoracotomy. After surgery, patients were free from air leak symptoms for a mean time of 176 days (range 25-477). Pulmonary function progressively deteriorated, and all the patients eventually died because of respiratory failure after a mean time of 483 days (range 127-1045) after the first episode of air leak. CONCLUSIONS: Surgery provides temporary relief to symptoms related to TALS but has limited effects on the underlying pathophysiologic process. The development of TALS in a sign of progressive pulmonary function worsening and is associated with high risk of respiratory failure and mortality.

PURPOSE: The search for an inexpensive agent for chemical pleurodesis in malignant pleural effusion (MPE) continues. We aimed to compare the efficacy and safety of iodopovidone versus doxycycline for pleurodesis in MPE. METHODS: We randomized consecutive subjects with recurrent symptomatic MPE (1:1) to undergo pleurodesis with either doxycycline or iodopovidone administered through an intercostal tube. The primary outcome was the success rate of pleurodesis at 30 days. The secondary outcomes were the time to pleurodesis, chest pain (assessed using visual analog scale [VAS]) after pleurodesis, and complications (hypotension, acute respiratory failure, empyema). RESULTS: We randomized 52 and 58 subjects to receive either doxycycline or iodopovidone. The mean (standard deviation [SD]) age of the study population (51% women) was 54.1 (13.6) years. Lung cancer (≥ 60%) was the most common underlying cause of MPE. We observed a similar frequency of success in the doxycycline vs. the iodopovidone group (complete response: 43 (82.7%) vs. 46 (79.3%) subjects; partial response: 7 (13.5%) vs. 10 (17.2%) subjects; p = 0.3). The mean (SD) time to pleurodesis was 1.5 (1.9) days and 1.9 (5.4) days in the doxycycline and iodopovidone groups, respectively. While the VAS for chest pain was significantly higher with iodopovidone (mean [SD] VAS: doxycycline, 31.9 [20.9]; iodopovidone, 41.3 [21.8]; p = 0.017), it did not reach the minimal clinically important difference. The complication rates were similar between the two groups. CONCLUSION: Iodopovidone was not superior to doxycycline for pleurodesis in MPE.

Chylothorax is a known complication of postcardiac surgery and the most common cause of pleural effusion in neonates. Conservative management is usually adopted, including Nil-per-Oral (NPO), treatment of underlying etiology of infection, and use of octreotide. Chylothorax resistant to medical therapy and drainage is often treated by chemical pleurodesis. Previously used pleurodesis agents have included talc, minocycline, OK-432, bleomycin, and povidone-iodine. 50% Dextrose (D50) has been reported to be useful for pleurodesis in adults. We successfully managed two cases of prematurely born infants with D50 as an alternative chemical sclerosant for chemical pleurodesis in a resistant chylothorax and discussed evidence of its use in the literature.

The patient was a 42-year-old woman. After 4 courses of capecitabine therapy for right chest wall recurrence of breast cancer, ER(+, 10-15%), PgR(-), HER2(-), she underwent pleurodesis using OK-432 for increased right pleural effusion. On the 12th day after pleurodesis diffuse infiltrative shadows in the right lung, and frosted shadows in both lungs, were observed, and she was diagnosed with drug-induced lung injury. About 3 weeks after administration of prednisolone 1 mg/ kg a tendency for improvement in lung injury was observed, but the patient died of breast cancer progression. Drug- induced lung injury by pleurodesis carries the risk of delaying resumption of chemotherapy. We report this case with a review of the literature.

BACKGROUND: A well-recognized therapy to improve the symptoms of patients with malignant pleural effusion (MPE), indwelling pleural catheters (IPCs) can also achieve spontaneous pleurodesis. Chemical pleurodesis is associated with a significant pro-coagulation and fibrinolytic environment. Hence, anticoagulation could theoretically interfere with this process. OBJECTIVE: The aim of this study was to evaluate if anticoagulation can interfere with successful spontaneous pleurodesis in patients treated with IPC. METHODS: This was a cohort study of all patients with MPE treated with IPC. The primary objective was to determine if anticoagulant use after IPC placement decreased the rate of spontaneous pleurodesis. The secondary objective was to identify other factors associated with spontaneous pleurodesis. We used a Fine-Gray subdistribution hazard model and a direct acyclic graph to identify variables associated with time to spontaneous pleurodesis. RESULTS: Of the included 410 patients, 210 patients (51.2%) achieved pleurodesis and had their IPC removed. We found no association between anticoagulation and likelihood of pleurodesis. Multivariate analyses revealed that prior chemotherapy, ECOG score of 2-4 were associated with unsuccessful pleurodesis, while chemotherapy or radiotherapy after IPC placement remained associated with increased likelihood of spontaneous pleurodesis. CONCLUSIONS: We failed to demonstrate an association between anticoagulation and pleurodesis. We found that better performance status and chemotherapy or radiotherapy after IPC placement can increase the rate of pleurodesis and catheter removal.

PURPOSE: To compare malignant pleural effusion (MPE) treatment outcomes and complications among patients receiving indwelling pleural catheter (IPC), talc pleurodesis (TPS), or dual therapy. Outcomes were determined by measuring length of stay (LOS) and post-procedure dyspnea scores. Complications were measured by comparing intervention failures and adverse events. METHODS: The Veterans Affairs' Corporate Data Warehouse was utilized to retrospectively review the charts of 314 MPE subjects. Dyspnea scores were estimated by researchers and LOS was determined by adding the duration of stay for all admissions post procedure. Complications were recorded through chart review. RESULTS: IPC exhibited higher failure rates than the other approaches 1 year post intervention. Pneumonia/chest infection rate and lung entrapment were also more prevalent. There was no significant difference in dyspnea rates. LOS illustrated a significant difference between groups, with talc patients spending a median of 7 days in the hospital immediately post procedure, while IPC and IPC + TPS patients spent a median of 3 and 2 days, respectively. CONCLUSION: Patients receiving IPC or combination treatment spend fewer days in the hospital than TPS patients. However, IPC appears to be associated with more adverse events and higher long-term failure rates than other management strategies.

An interventional pulmonologist possesses expertise in minimally invasive diagnostic and therapeutic procedures involving the airways, lungs and pleura. A malignant pleural effusion (MPE), which occurs in 20% of cancer patients, can be a daunting diagnostic challenge insofar as the pleural cavity is a closed cavity. In these patients, treatment may consequently be delayed before a precise diagnosis can be given. In the meantime, an interventional pulmonologist is called upon to carry out a wide range of examinations in order to establish the etiological diagnosis and to treat the symptoms of an MPE patient. Classical medical thoracoscopy, also called "pleuroscopy", is the reference method in MPE diagnosis because it allows visualization of the pleural cavity, pleural biopsy under direct visual control, providing excellent diagnostic yield. Over the past decade, new diagnostic methods have emerged, such as ultrasound-guided biopsy, as well as different interventions, such as indwelling pleural catheters, aimed at improving the quality of life of MPE patients, for whom therapeutic options are limited. The objective of this review of the literature is to point out the role of the interventional pulmonologist in the management of MPE by detailing the various diagnostic and therapeutic methods he possesses at the present time.

This interim report presents the results of pleurodesis with 50 ml of 50% glucose solution for patients with inoperable pneumothorax. Twenty patients were enrolled, and treatment was performed for 22 sites in total. The degree of lung collapse was mild in 2 cases, moderate in 12 cases, and severe in 8 cases. The mean number of treatments was 1.4 times (range 1~3). Mild chest pain after injection occurred in one case, and additional chest tube insertion was required for pleural effusion in one case. Other side effects, such as fever or dehydration, were not observed. On day one the mean blood glucose level was 145.0 mg/dl (range 103~259), and the mean pleural effusion volume was 284.6 ml (range 5~910). The air leakage was successfully controlled in 20 of the 22 sites( 91%). Pleurodesis in this manner was thought to be useful intervention for inoperable patients with pneumothorax.

OBJECTIVE: Empyema is a complication of talc-pleurodesis that may lead to further surgical intervention and death. Therefore, the present study's objective was to identify the risk factors for the development of post-pleurodesis empyema after talc slurry pleurodesis in order to better select patients for this procedure and minimize its morbidity. METHODS: Patients with malignant pleural effusion who underwent talc slurry pleurodesis at the present institution from January 2018 to January 2020 were retrospectively analyzed. Post-pleurodesis empyema was defined as pleural infection up to 30 days after pleurodesis. Using Cox regression analysis, significant prognostic factors for the development of empyema were examined. RESULTS: Of the 86 patients identified for inclusion in the study, 62 were women (72%). Their mean age was 56.3±12.6 years. The median pleural drainage time was 9 days, and 20 patients (23.3%) developed empyema. In the univariate analysis, both drainage time (p = 0.038) and the use of antibiotics prior to pleurodesis (p < 0.001) were risk factors for pleural empyema. Multivariate analysis also identified the use of antibiotics as an independent risk factor (Odds Ratio [OR] 9.81; 95% Confidence Interval [95% CI] 2.87â33.54). Although the pulmonary expansion was not associated with empyema in the multivariate analysis, patients with less than 50% pulmonary expansion had a 4.5-times increased risk of empyema (95% CI 0.90â22.86; p = 0.067), and patients with 50â70% pulmonary expansion had a 3.8-times increased risk of empyema (95% CI 0.98â15; p = 0.053) after pleurodesis. CONCLUSION: The study suggests that antibiotic therapy prior to talc slurry pleurodesis may increase the risk of developing empyema. Furthermore, pleurodesis should be considered with caution in patients with long-duration chest tube placement and incomplete lung expansion.

PURPOSE: The best treatment strategy for primary spontaneous pneumothorax is controversial and varies widely in practice. METHODS: Literatures were searched from databases till 24 August 2021. A Bayesian network meta-analysis was conducted to compare the outcomes of various treatments with the following endpoints: recurrence rate, postoperative chest tube duration, postoperative air leakage duration, length of hospital stay, and complications rate. RESULTS: In all, 7210 patients of 20 randomized controlled trials and 17 cohort studies were included. Surgery had a significantly lower recurrence rate compared to other treatments. Besides, bullectomy (BT) combined with chemical pleurodesis (CP), mechanical pleurodesis, or staple line coverage (SLC) can reduce the recurrence rate compared to BT alone, but none of them were statistically significant. In terms of reducing chest tube duration, BT with tubular Neoveil outperformed BT + pleural abrasion (mean difference [MD], 95% confidence interval [CI]: -2.5 [-4.63, -0.35]) and BT + apical pleurectomy (MD, 95% CI: -2.72 [-5.16, -0.27]). CONCLUSIONS: Surgical methods were superior to manual aspiration (MA), chest tube drainage (CTD), and conservative treatment in terms of recurrence reduction. There was no significant difference between MA and CTD in reducing the recurrence rate. Among surgical methods, CP is more effective than mechanical pleurodesis and SLC among the additional procedures based on BT.

An air leak lasting more than 5-7 days (persistent air leak, PAL) can complicate up to 40% of patients with secondary spontaneous pneumothorax. Chronic obstructive pulmonary disease is the most common cause of secondary spontaneous pneumothorax, and early surgical intervention has been recommended for patients with PAL. Bullectomy or blebectomy with concomitant mechanical pleurodesis by medical thoracoscopy or video assisted thoracoscopic surgery is considered definitive therapy. Unfortunately, the perioperative course following lung resection can also be complicated by air leaks leading to worse clinical outcomes. Post lung resection air leak can be pressure independent or pressure dependent (also known as drainage-related air leak). The distinction between these two entities is crucial as the management varies drastically. Pleural manometry may play an important role in the early diagnosis of pressure-dependent PAL preventing further unnecessary surgical procedures from being performed.

A 9-week-old male intact Cavalier King Charles Spaniel was presented for evaluation of acute onset dyspnea caused by left-sided pneumothorax. Thoracic computed tomography (CT) identified multiple pulmonary bullae and blebs in multiple lung lobes. Rupture of ≥1 pulmonary blebs or bullae, precipitated by low impact trauma, was the suspected cause of pneumothorax. A volume of 7.5 mL/kg of fresh whole blood was collected from a type-matched donor dog and administered into the left pleural space using a thoracostomy tube. The pneumothorax was successfully resolved and no adverse effects of blood patch pleurodesis were noted. The dog was clinically normal 12 months later.

INTRODUCTION: Malignant pleural effusions (MPEs) are common. MPE causes significant breathlessness and impairs quality of life. Indwelling pleural catheters (IPC) allow ambulatory drainage and reduce hospital days and re-intervention rates when compared to standard talc slurry pleurodesis. Daily drainage accelerates pleurodesis, and talc instillation via the IPC has been proven feasible and safe. Surgical pleurodesis via video-assisted thoracoscopic surgery (VATS) is considered a one-off intervention for MPE and is often recommended to patients who are fit for surgery. The AMPLE-3 trial is the first randomised trial to compare IPC (±talc pleurodesis) and VATS pleurodesis in those who are fit for surgery. METHODS AND ANALYSIS: A multi-centre, open-labelled randomised trial of patients with symptomatic MPE, expected survival of ≥ 6 months and good performance status randomised 1:1 to either IPC or VATS pleurodesis. Participant randomisation will be minimised for (i) cancer type (mesothelioma vs non-mesothelioma); (ii) previous pleurodesis (vs not); and (iii) trapped lung, if known (vs not). Primary outcome is the need for further ipsilateral pleural interventions over 12 months or until death, if sooner. Secondary outcomes include days in hospital, quality of life (QoL) measures, physical activity levels, safety profile, health economics, adverse events, and survival. The trial will recruit 158 participants who will be followed up for 12 months. ETHICS AND DISSEMINATION: Sir Charles Gairdner and Osborne Park Health Care Group (HREC) has approved the study (reference: RGS356). Results will be published in peer-reviewed journals and presented at scientific meetings. DISCUSSION: Both IPC and VATS are commonly used procedures for MPE. The AMPLE-3 trial will provide data to help define the merits and shortcomings of these procedures and inform future clinical care algorithms.

OBJECTIVES: Breast and ovarian cancer account for over 30% of malignant pleural effusions (MPEs). Treatment of the metastatic disease requires control of the MPE. Even though primarily symptomatic, the treatment of the MPE can potentially affect the oncological course of the disease. The aim of this review is to analyze the effectiveness of intrathoracic chemotherapy in the treatment of MPE caused by breast and ovarian cancer. METHODS: A systematic literature research was conducted up until May 2021. Studies published in English on patients undergoing either surgical or interventional intrapleural chemotherapy were included. RESULTS: Thirteen studies with a total of 497 patients were included. Analysis was performed on 169 patients with MPE due to breast cancer and eight patients with MPE secondary to ovarian cancer. The pooled success rates of intrathoracic chemotherapy for controlling the MPE were 59.1% and 87.5%, respectively. A survival analysis was not possible with the available data. The overall toxicity of the treatment was low. CONCLUSIONS: Intrathoracic chemotherapy achieves symptomatic control of the MPE in 59.1% of patients with metastatic breast cancer and 87.5% of patients with metastatic ovarian cancer. This is inferior to other forms of surgical pleurodesis. Data from small case series and studies on intraperitoneal chemotherapy show promising results. However, formal oncological studies on the use of intrathoracic chemotherapy for metastatic breast or ovarian cancer are lacking. Further prospective pilot studies are needed to assess the therapeutic oncological effects of this treatment.
