Comparison between OK-432 and Talc for pleurodesis in patients with persistent pulmonary air leak: a Japanese nationwide retrospective database study.

OBJECTIVES: OK-432 (Picibanil®) and talc are used in patients with persistent pulmonary air leaks. However, it is unclear which of these two agents is more effective. METHODS: This retrospective study used data from the Japanese Diagnosis Procedure Combination inpatient database. Patients with pneumothorax who underwent chemical pleurodesis between July 2010 and March 2022 were included in this study. The patients were categorized into two groups: the OK-432 and talc groups. The primary outcome measure was treatment failure, defined as a composite of requirement for additional surgical procedures, bronchoscopic interventions, or chemical pleurodesis. The secondary outcome measures were in-hospital mortality, length of hospital stay, 30-day readmission, and incidence of interstitial lung diseases after hospitalization. To compare the outcomes between the groups, 1:4 propensity score matching was conducted. RESULTS: Among the 4179 eligible patients, 3551 and 628 patients underwent chemical pleurodesis using OK-432 and talc, respectively. Propensity score matching yielded 2508 and 627 patients who underwent chemical pleurodesis using OK-432 and talc within seven days of admission, respectively. The frequency of treatment failure in the talc group (37.5% vs. 31.4%; P = 0.006) was lower than that in the OK-432 group with no significant differences in other outcomes. CONCLUSIONS: Medical professionals can consider talc as the initial pleurodesis agent for patients with persistent air leaks.

Robotic-Assisted Pleurectomy is a Safe and Effective Surgical Treatment for Spontaneous Pneumothorax.

INTRODUCTION: Spontaneous pneumothorax is a common thoracic surgical problem. To prevent recurrence, surgical options include blebectomy, mechanical or chemical pleurodesis, pleurectomy, or a combination of these operations. Pleurectomy is associated with lower recurrence rates but may be technically challenging via video-assisted thoracoscopic surgery. We report the first series of robotic-assisted pleurectomy (RAP) for spontaneous pneumothorax. METHODS: A retrospective, single-center analysis was conducted on consecutive patients undergoing RAP for spontaneous pneumothorax from 2017 to 2023. Patients with prior surgery on the same side for pneumothorax were excluded. Demographics, comorbidities, functional status, intraoperative and perioperative variables were collected. 30-d readmission, 30-d mortality, and recurrence were recorded. RESULTS: Thirty-six patients underwent RAP during the study period with a median follow-up of 36 mo. Patients had a median age of 41.5 (interquartile range [IQR] 21.5-68) y and were mostly male (80.6%) and past smokers (44.4%) with 66.6% having a primary spontaneous pneumothorax. The median time to chest tube removal was 3 d (IQR 2-3) and the median length of stay was two days (IQR 2-4). Complications occurred in seven patients with the majority (85.7%) having a grade 2 Clavien-Dindo classification score. There was no 30-d mortality or recurrence. CONCLUSIONS: Robotic-assisted pleurectomy for spontaneous pneumothorax is a safe and effective operation that can be used to prevent future recurrence.

Surgical management of pleural complications in lymphangioleiomyomatosis.

OBJECTIVE: Lymphangioleiomyomatosis (LAM) is a rare cystic lung disease occurring primarily in women. Pneumothorax and chylothorax are common pleural complications in LAM. We aim to explore various options in the surgical management of pleural disease in LAM. METHODS: A retrospective chart review of all patients at the Center for LAM and Rare Lung Diseases at Columbia University was performed, and date, type, and indication for surgical procedure were collected. All patients with any cystic lung disease seen between January 1, 2000, and March 1, 2023, were included in the database. RESULTS: The charts for 326 patients with possible LAM were reviewed, including 213 with confirmed LAM and 113 women with cystic lung disease consistent suspected to be LAM were reviewed. A total of 40.5% underwent surgical procedures at our institution or at referring hospitals. A total of 15.6% of patients underwent surgical lung biopsies. A total of 16.6% had a history of pneumothoraces, of whom 79.6% underwent chemical and/or mechanical pleurodesis, 14.8% required pleurectomy, and 7.4% were discharged with tunneled indwelling pleural catheters. We found that 5.6% of confirmed LAM patients have history of chylothorax, with thoracic duct ligation, thoracic duct embolization, pleurodesis, and pleurodesis with long-term tunneled indwelling pleural catheter placement all used as treatment strategies. CONCLUSIONS: Here we demonstrate the significant burden of pleural disease in patients with LAM. It is imperative that thoracic surgeons understand the high incidence of pneumothorax in this patient population. Tunneled indwelling pleural catheters are underutilized but provide long-term options for chylous management with long-term mechanical pleurodesis and a decrease in hospital length of stay.

Impact of Postoperative Prolonged Air Leakage on Long-Term Pulmonary Function after Lobectomy for Lung Cancer.

Background: This study aimed to evaluate the long-term impact of postoperative prolonged air leak (PAL) on pulmonary function. Methods: We enrolled 1,316 patients with pathologic stage I-III lung cancer who underwent lobectomy. The cohort was divided into 2 groups: those who experienced PAL (n=55) and those who did not (n=1,261). Propensity score matching was conducted at a 1:4 ratio, resulting in 49 patients in the PAL group and 189 in the non-PAL group. Changes in pulmonary function were compared among preoperative, 6-month postoperative, and 12-month postoperative measurements between the 2 groups. Results: The variables used for propensity score matching included age, sex, smoking history, body mass index, baseline pulmonary function, pathologic stage, and surgical approach. All standardized mean differences were less than 0.1. Six months postoperatively, the PAL group showed a greater reduction in both forced expiratory volume in 1 second (FEV1) (-13.0% vs. -10.0%, p=0.041) and forced vital capacity (FVC) (-15.0% vs. -9.0%, p<0.001) than the non-PAL group. In cases of upper lobectomy, there were no significant differences in FEV1 changes between the PAL and non-PAL groups at both 6 and 12 months. However, in lower lobectomy, the PAL group demonstrated a more pronounced decrease in FEV1 (-14.0% vs. -11.0%, p=0.057) and FVC (-20.0% vs. -13.0%, p=0.006) than the non-PAL group at 6 months postoperatively. Conclusion: Postoperative PAL delayed the recovery of pulmonary function after lobectomy. These effects were markedly more pronounced after lower lobectomy than after upper lobectomy.

An Evaluation of the Content Quality, Readability, and Reliability of Publicly Available Web-Based Information on Pneumothorax Surgery in Ireland.

Introduction The internet is increasingly the first port of call for patients introduced to new treatments. Unfortunately, many websites are of poor quality, thereby limiting patients' ability to make informed health decisions. Within thoracic surgery, the treatment options for pneumothoraces may be less intuitive for patients to understand compared to procedures such as lobectomies and wedge resections. Therefore, patients must receive high-quality information to make informed treatment decisions. No study to date has evaluated online information regarding pneumothorax surgery. Knowledge regarding the same may allow physicians to recommend appropriate websites to patients and supplement remaining knowledge gaps. Objective This study aims to evaluate the content, readability, and reliability of online information regarding pneumothorax surgery. Methods A total of 11 search terms including "pneumothorax surgery," "pleurectomy," and "pleurodesis" were each entered into Google, Bing, and Yahoo. The top 20 websites found through each search were screened, yielding 660 websites. Only free websites designed for patient consumption that provided information on pneumothorax surgery were included. This criterion excluded 581 websites, leaving 79 websites to be evaluated. To evaluate website reliability, the Journal of American Medical Association (JAMA) and DISCERN benchmark criteria were applied. To evaluate the readability, 10 standardized tools were utilized including the Flesch-Kincaid Reading Ease Score. To evaluate website content, a novel, self-designed 10-part questionnaire was utilized to assess whether information deemed essential by the authors was included. It evaluated whether websites comprehensively described the surgery process for patients, including pre- and post-operative care. Website authorship and year of publication were also noted. Results The mean JAMA score was 1.69 ± 1.29 out of 4, with only nine websites achieving all four reliability criteria. The median readability score was 13.42 (IQR: 11.48-16.23), which corresponded to a 13th-14th school grade standard. Only four websites were written at a sixth-grade reading level. In the novel content questionnaire, 31.6% of websites (n = 25) did not mention any side effects of pneumothorax surgery. Similarly, 39.2% (n = 31) did not mention alternative treatment options. There was no correlation between the date of website update and JAMA (r = 0.158, p = 0.123), DISCERN (r = 0.098, p = 0.341), or readability (r = 0.053, p = 0.606) scores. Conclusion Most websites were written above the sixth-grade reading level, as recommended by the US Department of Health and Human Services. Furthermore, the exclusion of essential information regarding pneumothorax surgery from websites highlights the current gaps in online information. These findings emphasize the need to create and disseminate comprehensive, reliable websites on pneumothorax surgery that enable patients to make informed health decisions.

Successful resolution of a continuous pneumothorax using canine xeno-blood patch pleurodesis in a cat.

Case summary: An 11-year-old male neutered cat was referred to The Ohio State University's Veterinary Teaching Hospital after being diagnosed with pleural effusion by a referral veterinarian. After thoracocentesis, analysis of the effusion was consistent with chyle. Echocardiography, radiographs and bloodwork were used to diagnose hypertrophic cardiomyopathy phenotype and left-sided congestive heart failure, suspected to be secondary to uncontrolled hyperthyroidism. While initiating medical therapy, repeated thoracocenteses were required. A severe pneumothorax developed, necessitating placement of bilateral thoracostomy tubes. A thoracic CT scan did not reveal a cause for the pneumothorax; therefore, it was suspected to have occurred secondarily to an iatrogenic laceration of the parenchyma during thoracocentesis. An autologous blood patch pleurodesis was considered contraindicated so instead the cat was administered a blood patch using blood from a canine blood donor. The cat's respiratory status remained stable without additional intervention. At 30 h after blood patch pleurodesis, the thoracostomy tubes were removed and thoracic radiographs revealed near resolution of the pleural effusion and pneumothorax. The cat remained subclinical and was discharged from the hospital 48 h after the blood patch pleurodesis. Upon follow-up at 4 and 8 weeks after discharge, the cat was alive and had no complications or adverse reactions from the blood patch pleurodesis. Relevance and novel information: This case documents the first report of a xeno-blood patch pleurodesis performed in a cat using blood from a canine donor. The cat had a successful discharge from the hospital with no adverse reactions from the xeno-blood patch pleurodesis.

Malignant Pleural Effusion: A Multidisciplinary Approach.

Management of spontaneous pneumothorax: a mini-review on its latest evidence.

Spontaneous pneumothorax usually presents as a medical emergency and requires prompt attention and treatment. In patients with underlying lung diseases, it is often associated with prolonged hospitalization, persistent air leak and also a high rate of recurrence. It brings considerable clinical burden to patients and therefore advancement of spontaneous pneumothorax management is eagerly anticipated. In recent years, conservative approach with avoidance of invasive treatment has risen to be a main consideration for primary spontaneous pneumothorax (PSP) patients who are clinically stable with minimal symptoms. The body of evidence in secondary spontaneous pneumothorax (SSP) group is less robust compared with that in PSP group. Non-surgical treatment in SSP is becoming more common due to concerns about morbidity and mortality after surgical pleurodesis as patients are usually older with more underlying medical diseases. Until last year, there have been no updates on the international recommendation of pneumothorax management since the British Thoracic Society (BTS) guideline published in 2010. The latest 2023 BTS guideline on pleural diseases provides us a good opportunity to review the latest development and literature of the care for patients with spontaneous pneumothorax. This article will explore the goals of pneumothorax treatment including air evacuation, cessation of persistent air leak and prevention of recurrence.

The role of day-case thoracoscopy at a district general hospital: A real world observational study.

Objective: To assess the feasibility and safety of talc pleurodesis performed as part of day-case medical thoracoscopy. Methods: A Richard Wolf® 5 mm mini thoracoscope through a 5.5 mm port was used with eligible cases having talc poudrage followed by insertion of indwelling pleural catheter (IPC). District nurses drain the IPC daily for the first 5 days. Once the drain output is <150 mL, the frequency is progressively reduced to once weekly. The drain is removed after two consecutive dry taps 1 week apart. Results: Overall, 51 patients underwent day-case thoracoscopy. Median time to removal of IPC for our day-case protocol was 14 days. There were seven deaths within 70 days among 41 patients with malignant pleural effusion in the day-case cohort, compared to eight deaths in the 33 conventional thoracoscopy controls. Overall, the day-case cohort observed a statistically significant reduction in all-cause mortality at 180 days compared to the conventional cohort (log rank p = 0.024). The average cost per patient of the day-case and inpatient cohort was £1,328.0 ± 106.0 and £1,835.0 ± 295.0 (p = 0.961). Conclusion: This study suggests that thoracoscopy and talc poudrage can be performed safely as a day-case procedure. Further data are needed to ascertain long-term outcomes.

[Treatment of malignant effusion]. / Sravnitel'naya kharakteristika metodov lecheniya metastaticheskogo plevrita (obzor literatury).

Malignant effusion complicates more than 15% of all cancers in delayed stages of progression. The most common causes of metastatic pleuritis are lung cancer, breast cancer, ovarian cancer, lymphoproliferative diseases or dissemination of gastrointestinal tumors. Malignant effusion is associated with negative prognosis for overall survival regardless of etiology of tumor, significantly complicates the course of the underlying disease, impairs life quality and complicates treatment. Despite various methods for pleural cavity obliteration in recurrent metastatic pleuritis, there is still no a uniform approach to choosing the optimal treatment strategy. We analyzed the main methods of conservative and surgical treatment of recurrent metastatic pleuritic regarding efficacy, risk of recurrence and reproducibility.

Predictors of surgical intervention in first episode primary spontaneous pneumothorax requiring chest drain insertion.

BACKGROUND: Primary spontaneous pneumothorax occurs in patients with no underlying lung disease and guidelines recommend chest tube drainage for the first episode, with surgical intervention reserved for recurrent episodes, persistent air leak or failure of lung re-expansion. Modern surgical management is associated with reduced length of hospital stay and superior freedom from recurrence compared with chest tube drainage alone. The objective of this study was to identify risk factors for failed chest tube drainage in patients who present with first episode primary spontaneous pneumothorax. METHODS: A retrospective analysis of patients who presented to Royal Prince Alfred Hospital, Australia with first episode PSP and underwent chest tube insertion was performed. Patient demographics and size of pneumothorax were examined in relation to the primary outcome, a composite of failed chest tube drainage and recurrent ipsilateral pneumothorax. RESULTS: Fifty-five patients underwent chest tube drainage for first episode primary spontaneous pneumothorax between 1st January 2017 and 31st December 2020. Complete lung collapse on admission chest x-ray was associated with an increased risk of the primary outcome (63% versus 19%, OR 7.3 [96% CI 2.0-27.4), P = 0.004). CONCLUSION: This small retrospective study found that patients that undergo chest drain insertion for first episode primary spontaneous pneumothorax who present with complete lung collapse on admission are at high risk of requiring pleurodesis and therefore may benefit from early surgical referral.

The Clinical and Economic Implications of Different Treatment Pathways for Patients With Rapidly Recurrent Malignant Pleural Effusion.

BACKGROUND: Malignant pleural effusion (MPE) is a common cancer complication. Clinical and economic implications of different recurrent MPE treatment pathways have not been evaluated fully. RESEARCH QUESTION: What clinical outcomes, complications, health care resource use, and costs are associated with various rapidly recurrent MPE treatment pathways? STUDY DESIGN AND METHODS: This retrospective cohort study using Surveillance, Epidemiology and End Results Medicare data (2011-2015) included patients 66 to 90 years of age with rapidly recurrent MPE. Rapid recurrence was defined as receipt of a second pleural procedure within 14 days of the first thoracentesis, including nondefinitive repeated thoracentesis or a definitive treatment option including chest tube, indwelling pleural catheter (IPC), or thoracoscopy. RESULTS: Among 8,378 patients with MPE, 3,090 patients (36.9%) had rapidly recurrent MPE (mean ± SD age, 75.9 ± 6.6 years; 45.6% male; primary cancer, 62.9% lung and 37.1% other). Second pleural procedures were nondefinitive thoracentesis (62.3%), chest tube (17.1%), IPC (13.2%), or thoracoscopy (7.4%). A third pleural procedure was required more frequently if the second pleural procedure was nondefinitive thoracentesis vs chest tube placement, IPC placement, or thoracoscopy (70.3% vs 44.1% vs 17.9% vs 14.4%, respectively). The mean number of subsequent pleural procedures over the patient's lifetime varied significantly among the procedures (1.74, 0.82, 0.31, and 0.22 procedures for patients receiving thoracentesis, chest tube, IPC, and thoracoscopy, respectively; P < .05). Average total costs after the second pleural procedure to death adjusted for age at primary cancer diagnosis, race, year of second pleural procedure, Charlson comorbidity index, cancer stage at primary diagnosis, and time from primary cancer diagnosis to diagnostic thoracentesis were lower with IPC ($37,443; P < .0001) or chest tube placement ($40,627; P = .004) vs thoracentesis ($47,711). Patients receiving thoracoscopy ($45,386; P = .5) incurred similar costs as patients receiving thoracentesis. INTERPRETATION: Early definitive treatment was associated with fewer subsequent procedures and lower costs in patients with rapidly recurrent MPE.

Intrapleural minocycline pleurodesis for bilateral pneumothorax due to septic pulmonary embolism: a case report.

Background: Pneumothorax is a rare but serious complication of septic pulmonary embolism (SPE). SPE is a life-threatening disorder wherein infected thrombi bring infarction of the terminal and small caliber parts of the pulmonary vasculature and develop multiple nodular and cavitary lesions. Interventions other than conservative chest tube drainage for pneumothorax due to SPE have rarely been reported. Here, we present a case of bilateral pneumothorax due to SPE treated with intrapleural minocycline pleurodesis. Case Description: A 72-year-old male patient previously diagnosed as esophageal carcinoma developed metachronous bilateral pneumothorax while treated for brain metastases. Based on blood cultures and chest computed tomography images, he was diagnosed with pneumothorax secondary to SPE due to methicillin-susceptible Staphylococcus aureus bacteremia. Bilateral chest tube drainage was instituted. Continuous air leakage was found bilaterally after chest tube placement. He was treated with broad-spectrum antibiotics based on the susceptibility profile and supportive treatment for sepsis. Approximately 3 weeks later, air leakage significantly reduced. We performed intrapleural minocycline pleurodesis bilaterally to prevent the recurrence of pneumothorax; the left side was firstly treated and the right side was treated 2 weeks later. Both chest tubes were successfully removed two days after procedures. Although the patient finally died of brain metastases 1 month after pleurodesis, he never recurred pneumothorax. Conclusions: Intrapleural minocycline pleurodesis may be one of the useful and efficacious options in terms of treating intractable pneumothorax associated with SPE. Intrapleural minocycline pleurodesis could be a consideration for intractable pneumothorax related to SPE.

Treating Spontaneous Pneumothorax Using an Innovative Surgical Technique Called Capnodissection Pleurectomy: Case Report.

Spontaneous pneumothorax is one of the most common conditions encountered in thoracic surgery. This condition can be treated conservatively or surgically based on indications and guidelines. Traditional surgical management includes pleurodesis (mechanical or chemical) in addition to bullectomy if the bullae can be identified. Mechanical pleurodesis is usually performed by surgical pleurectomy or pleural abrasion. In this case report, we present a case of a young patient with spontaneous pneumothorax who needed a surgical intervention. We performed a new, innovative surgical technique for surgical pleurectomy where we used carbon dioxide for dissection of the parietal pleura (capnodissection). This technique may provide similar efficiency to the traditional procedure but with less risk of bleeding and complications.

Predictive factors of early autologous blood pleurodesis for postoperative air leak.

BACKGROUND: The usefulness of autologous blood pleurodesis for air leak after pulmonary resection is well known; however, factors predicting the therapeutic efficacy are poorly understood. Herein, we aimed to examine the predictors of early autologous blood pleurodesis for air leak following pulmonary resection. METHODS: Patients who underwent pulmonary resection and autologous blood pleurodesis with thrombin for postoperative air leak between January 2016 and October 2022 were retrospectively analyzed. Patients received 50-100 mL of autologous blood and 20,000 units of thrombin on postoperative days 1-4. If necessary, the same procedure or pleurodesis with other chemical agents was repeated until the air leak stopped. Patients were divided into single-dose and multiple-dose groups based on the number of times pleurodesis had occurred before the air leak stopped and were statistically analyzed. Logistic regression analysis was performed to identify predictors of treatment efficacy. RESULTS: Of the 922 patients who underwent pulmonary resection, 57 patients (6.2%) were included and divided into single-dose (n = 38) and multiple-dose (n = 19) groups. The amount of air leaks was identified as a significant predictor of multiple dosing, with a cutoff of 60 mL/min, in multivariate logistic regression analyses (odds ratio 1.13, 95% CI 1.03-1.24, p = 0.0065). The multiple-dose group showed a significantly higher recurrence of air leak (p = 0.0417). CONCLUSIONS: The amount of air leaks after pulmonary resection is the only significant factor predicting whether multiple autologous blood pleurodesis is required, and the recurrence rate of pneumothorax is significantly higher in such cases.

Endobronchial Valves in Treatment of Persistent Air Leak: European Case-Series Study and Best Practice Recommendations - From an Expert Panel.

INTRODUCTION: Persistent air leak (PAL) is associated with prolonged hospitalization, high morbidity and increased treatment costs. Conservative treatment consists of observation, chest tube drainage, and pleurodesis. Guidelines recommend surgical evaluation if air leak does not respond after 3-5 days. One-way endobronchial valves (EBV) have been proposed as a treatment option for patients with PAL in which surgical treatment is not feasible, high risk or has failed. We aimed to provide a comprehensive overview of reported EBV use for PAL and issue best practice recommendations based on multicenter experience. METHODS: We conducted a retrospective observational case-series study at four different European academic hospitals and provided best practice recommendations based on our experience. A systematic literature review was performed to summarize the current knowledge on EBV in PAL. RESULTS: We enrolled 66 patients, male (66.7%), median age 59.5 years. The most common underlying lung disease was chronic obstructive pulmonary disease (39.4%) and lung cancer (33.3%). The median time between pneumothorax and valve placement was 24.5 days (interquartile range: 14.0-54.3). Air leak resolved in 40/66 patients (60.6%) within 30 days after EBV treatment. Concerning safety outcome, no procedure-related mortality was reported and complication rate was low (6.1%). Five patients (7.6%) died in the first 30 days after intervention. CONCLUSION: EBV placement is a treatment option in patients with PAL. In this multicenter case-series of high-risk patients not eligible for lung surgery, we show that EBV placement resulted in air leak resolution in 6 out of 10 patients with a low complication rate. Considering the minimally invasive nature of EBV to treat PAL as opposed to surgery, further research should investigate if EBV treatment should be expanded in low to intermediate risk PAL patients.

Chylothorax in Infants and Children After Congenital Heart Surgery: Approach and Review.

Chylothorax in infants after surgery for congenital heart disease is associated with significant morbidity and mortality. Numerous management modalities applied alone or in various combinations have been utilized but definitive guidelines have not yet been established. We present two infants who developed refractory chylothorax after congenital heart surgery. We also reviewed evidence for the use of available treatment modalities. In our experience, the use of lymphangiography followed by pleurodesis by povidone-iodine was safe and our impression was that it may have played a decisive role in controlling the lymph leak.

Early Onset of Severe Interstitial Pneumonitis Associated With Anti-PD-1 Immune Checkpoint Antibody After Pleurodesis.

We present a case of lung adenocarcinoma with malignant pleural effusion. Nineteen days after pleurodesis using minocycline and OK-432 (picibanil), pembrolizumab monotherapy was initiated. Four days later, the patient experienced a persistent cough. Chest computed tomography showed that ground-glass opacity appeared on the same side as pleurodesis and spread bilaterally thereafter, which was diagnostic of immune checkpoint inhibitors (ICI)-related pneumonitis. As he presented a severe respiratory failure, corticosteroid therapy was administered. Two weeks later, respiratory failure completely resolved and the abnormal shadows dramatically improved. Our results indicate that severe ICI-related pneumonitis can develop within a short period after pleurodesis.

Medical thoracoscopy with talc pleurodesis for refractory hepatic hydrothorax: A case series of three successes.

Medical thoracoscopy with chemical pleurodesis is a last resort for managing patients who suffer. from recurrent hepatic hydrothorax. However, despite pleurodesis, the rapid fluid build-up can hinder the successful apposition of the pleural surfaces. To improve the chances of success, we investigated the effectiveness of abdominal paracentesis before chemical pleurodesis via medical thoracoscopy to reduce significant fluid shifts from the peritoneal to the pleural cavity. We present a series of three patients with liver cirrhosis complicated by hepatic hydrothorax who underwent medical thoracoscopy with talc pleurodesis. Before the procedure, we optimised medical treatment, and if needed, we performed large-volume paracentesis to prevent rapid reaccumulation of pleural fluid. All study subjects achieved treatment success, defined as relief of breathlessness and absence of pleural effusion at 12 months. Complications related to the treatment included hepatic encephalopathy and acute kidney injury, which were managed conservatively. To manage symptomatic and recurrent hepatic hydrothorax, medical thoracoscopy with talc pleurodesis, preceded by the evacuation of ascites, can be considered as a treatment option. This procedure should be considered early for those who do not respond to medical management and are not suitable candidates for TIPS or liver transplantation.

Advancements in the Management of Postoperative Air Leak following Thoracic Surgery: From Traditional Practices to Innovative Therapies.

Background: Postoperative air leak (PAL) is a frequent and potentially serious complication following thoracic surgery, characterized by the persistent escape of air from the lung into the pleural space. It is associated with extended hospitalizations, increased morbidity, and elevated healthcare costs. Understanding the mechanisms, risk factors, and effective management strategies for PAL is crucial in improving surgical outcomes. Aim: This review seeks to synthesize all known data concerning PAL, including its etiology, risk factors, diagnostic approaches, and the range of available treatments from conservative measures to surgical interventions, with a special focus on the use of autologous plasma. Materials and Methods: A comprehensive literature search of databases such as PubMed, Cochrane Library, and Google Scholar was conducted for studies and reviews published on PAL following thoracic surgery. The selection criteria aimed to include articles that provided insights into the incidence, mechanisms, risk assessment, diagnostic methods, and treatment options for PAL. Special attention was given to studies detailing the use of autologous plasma in managing this complication. Results: PAL is influenced by a variety of patient-related, surgical, and perioperative factors. Diagnosis primarily relies on clinical observation and imaging, with severity assessments guiding management decisions. Conservative treatments, including chest tube management and physiotherapy, serve as the initial approach, while persistent leaks may necessitate surgical intervention. Autologous plasma has emerged as a promising treatment, offering a novel mechanism for enhancing pleural healing and reducing air leak duration, although evidence is still evolving. Conclusions: Effective management of PAL requires a multifaceted approach tailored to the individual patient's needs and the specifics of their condition. Beyond the traditional treatment approaches, innovative treatment modalities offer the potential to improve outcomes for patients experiencing PAL after thoracic surgery. Further research is needed to optimize treatment protocols and integrate new therapies into clinical practice.
