RESUMO
PURPOSE: We aimed to identify preoperative risk factors for secondary spontaneous pneumothorax surgery. METHODS: The National Clinical Database of Japan, with six annual datasets from 2014 to 2019, was used. All patients who underwent surgery for secondary spontaneous pneumothorax were included, excluding those < 15 years old and those with incomplete data. The effects of preoperative risk factors were analyzed for operative mortality (mortality during hospitalization or within 30 days, regardless of hospitalization status), 30-day mortality, and postoperative respiratory morbidities. RESULTS: Of the 18,309 patients enrolled in the study, operative mortality, 30-day mortality, and postoperative respiratory morbidities were observed in 654 (3.6%), 343 (1.9%), and 2258 (12.3%) patients, respectively. Increasing age, male sex, body mass index < 18.5 or > 30, performance status > 2, emergent surgery, interstitial pneumonia, and diabetes in preoperative co-morbidity, tumors, and other diseases in underlying lung disease were significant risk factors for operative mortality. Those for 30-day mortality included autoimmune disease instead of male sex and diabetes, while those for postoperative respiratory morbidities included lymphangiomyomatosis instead of a body mass index > 30. CONCLUSION: We identified many preoperative risk factors for operative mortality, 30-day mortality, and postoperative respiratory morbidities in secondary spontaneous pneumothorax surgery. These findings will assist in selecting appropriate surgical candidates.
RESUMO
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.

BACKGROUND: Optimal management of persistent air leaks (PALs) in patients with secondary spontaneous pneumothorax (SSP) remains controversial. OBJECTIVE: To evaluate the efficacy and safety of endobronchial autologous blood plus thrombin patch (ABP) and bronchial occlusion using silicone spigots (BOS) in patients with SSP accompanied by alveolar-pleural fistula (APF) and PALs. METHODS: This prospective multicentre randomized controlled trial compared chest tube-attached water-seal drainage (CTD), ABP, and BOS that were performed between February 2015 and June 2017 in one of six tertiary care hospitals in China. Patients diagnosed with APF experiencing PALs (despite 7 days of CTD) and inoperable patients were included. Outcome measures included success rate of pneumothorax resolution at the end of the observation period (further 14 days), duration of air leak stop, lung expansion, hospital stay, and complications. RESULTS: In total, 150 subjects were analysed in three groups (CTD, ABP, BOS) of 50 each. At 14 days, 60, 82, and 84% of CTD, ABP, and BOS subjects, respectively, experienced full resolution of pneumothorax (p = 0.008). All duration outcome measures were significantly better in the ABP and BOS groups than in the CTD group (p < 0.016 for all). The incidence of adverse events, including chest pain, cough, and fever, was not significantly different. All subjects in the ABP and BOS groups experienced temporary haemoptysis. Spigot displacement occurred in 8% of BOS subjects. CONCLUSION: ABP and BOS resulted in clinically meaningful outcomes, including higher success rate, duration of air leak stop, lung expansion, and hospital stay, with an acceptable safety profile.

In Germany, 10,000 cases of spontaneous pneumothorax are treated inpatient every year. The German Society for Thoracic Surgery, in co-operation with the German Society for Pulmonology, the German Radiological Society, and the German Society of Internal Medicine has developed an S3 guideline on spontaneous pneumothorax and post-interventional pneumothorax moderated by the German Association of Scientific Medical Societies. METHOD: Based on the source guideline of the British Thoracic Society (2010) for spontaneous pneumothorax, a literature search on spontaneous pneumothorax was carried out from 2008 onwards, for post-interventional pneumothorax from 1960 onwards. Evidence levels according to the Oxford Center for Evidence-Based Medicine (2011) were assigned to the relevant studies found. Recommendations according to grade (A: "we recommend"/"we do not recommend," B: "we suggest"/"we do not suggest") were determined in 3 consensus conferences by the nominal group process. RESULTS: The algorithms for primary and secondary pneumothorax differ in the indication for CT scan as well as in the indication for chest drainage application and video-assisted thoracic surgery. Indication for surgery is recommended individually taking into account the risk of recurrence, life circumstances, patient preferences, and procedure risks. For some forms of secondary pneumothorax, a reserved indication for surgery is recommended. Therapy of post-interventional spontaneous pneumothorax is similar to that of primary spontaneous pneumothorax. DISCUSSION: The recommendations of the S3 Guideline provide assistance in managing spontaneous pneumothorax and post-interventional pneumothorax. Whether this will affect existing deviant diagnostic and therapeutic measures will be demonstrated by future epidemiological studies.

PURPOSE: Secondary spontaneous pneumothorax (SSP) is difficult to treat by itself and due to its association with serious underlying diseases. It has a high rate of recurrence and often requires extended hospitalization. Therefore, we evaluated the outcome and risk factors associated with recurrence and extended hospitalization. METHODS: We retrospectively examined 61 patients with SSP, and evaluated the patients' characteristics, underlying diseases, introduction of home oxygen therapy, Brinkman index, and X-ray imaging findings to determine the risk factors for recurrence and extended hospitalization. RESULTS: There were 28 patients (46.0%) with chronic obstructive pulmonary disease, 8 (13.1%) with interstitial pneumonia, 16 (26.2%) with massive emphysema, and 9 (14.8%) with other diseases. Adhesion and mediastinal shift visualized by X-ray imaging were observed in 37 (37.9%) and 25 patients (40.1%), respectively. Recurrence occurred in 25 patients (40.9%) and the average hospitalization duration was 14.5 days (±11.2). A multivariate analysis showed that adhesion on X-ray imaging was a significant risk factor for recurrence (odds ratio 4.90, 95% confidence interval 1.38-21.44) and mediastinal shift on X-ray imaging was a significant risk factor for extended hospitalization (odds ratio 6.05, 95% confidence interval 1.44-31.06). CONCLUSIONS: Findings from X-ray imaging, and not underlying diseases, are risk factors for recurrence and extended hospitalization.

Awake video-assisted thoracic surgery (VATS) is a therapeutic option for patients with intractable secondary spontaneous pneumothorax (SSP) complicated by impaired pulmonary function. The preoperative identification of air leak points is one of the keys to the success of this procedure. We describe how we performed saline-filled computed tomography (CT) thoracography to detect pleural fistulae in three patients with intractable SSP. Saline-filled CT thoracography showed bubble signs in two patients and an air-water level in bulla in one patient. The preoperative identification of air leak points resulted in successful awake VATS for all three patients. Our experience demonstrates that saline-filled CT thoracography is a useful diagnostic tool for SSP, especially when used in preparation for awake VATS when minimally invasive procedures are desirable.

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

We report on the "Triple-FP technique," a novel surgical approach for secondary spontaneous pneumothoraces, which combines a free pericardial fat pad, fibrin glue, and polyglycolic acid sheets. In our experience with 13 patients suffering from secondary spontaneous pneumothoraces, this method effectively prevented postoperative air leaks and re-operations. The technique includes the following steps: (1) harvesting free pericardial fat; (2) suturing around the lung parenchymal defect with the needles and thread left outside the thoracic cavity; (3) ensuring contact between the mediastinal pleural side of the fat and the lung; (4) applying fibrin glue to both the lung and fat before suturing; (5) securing the fat to the lung via the suture thread, reinforced with fibrin glue; and (6) stabilization with polyglycolic acid sheets and additional fibrin glue. This innovative technique is a reliable and effective treatment strategy for secondary spontaneous pneumothoraces, especially for patients with fragile lung tissue.
RESUMO
PURPOSES: Secondary spontaneous pneumothorax (SSP) is occasionally observed in elderly patients suffering from diffuse lung diseases. The purpose of this study was to analyze the outcomes of surgical treatment of SSP patients with chronic lung diseases. METHODS: In total, 242 patients who underwent surgery for spontaneous pneumothorax at Chiba University Hospital from January 2006 to October 2016 were included in this study. The patients' records were reviewed retrospectively for data on their background, surgical treatment, morbidity, mortality, and recurrence. RESULTS: Of the spontaneous pneumothorax cohort, primary spontaneous pneumothorax (PSP) accounted for 144 patients. Among the 98 patients with SSP, 57 cases were caused by chronic obstructive pulmonary disease (COPD) and 21 were caused by interstitial pneumonia (IP). The postoperative complication rate was 19.3% in the COPD group, 42.9% in the IP group, and 11.1% in the PSP group. The recurrence rate was 5.3% in the COPD group, 28.6% in the IP group, and 21.5% in the PSP group. CONCLUSIONS: The morbidity and recurrence were comparable between PSP and SSP cases with COPD, whereas these values were unfavorable in SSP cases with IP compared with PSP ones. Surgical intervention should be carefully considered in SSP patients with IP.

OBJECTIVES: This study aimed to explore the differences between primary spontaneous pneumothorax (PSP) and secondary spontaneous pneumothorax (SSP) in demographic and clinical features, management trends, and outcomes, alongside assessing recurrence risk factors in spontaneous pneumothorax (SP) patients. METHODS: This retrospective cohort study at New Damietta Hospital, Al-Azhar University, examined data from adults diagnosed with SP, differentiating between PSP and SSP types based on clinical and radiological criteria, to analyze demographics, clinical characteristics, management strategies, and outcomes. RESULTS: In a study of 170 patients, 42.94% were diagnosed with PSP and 57.06% with SSP, showing significant differences in age distribution (P=0.042) and smoking habits (P<0.001 for both tobacco and cannabis). Management approaches varied, with conservative methods more common in PSP (15.07%) and surgical interventions following intercostal tube (ICT) drainage significantly higher in SSP (40.21%, P=0.001). Length of hospital stay (LOS) and recurrence rates were significantly higher in SSP than PSP (P<0.001 for LOS; P=0.001 for recurrence), with postoperative complications and in-hospital mortality occurring exclusively in SSP (P=0.054 for complications, P<0.001 for mortality). Risk factors for recurrence included older age, presence of blebs/bullae (P<0.001), and lower hemoglobin and hematocrit levels (P=0.009 and P=0.008, respectively), with thoracic drainage duration longer in recurrent cases (P=0.008). Smoking status significantly impacted recurrence risk, with current smokers showing a higher risk compared to never-smokers (P=0.012). CONCLUSIONS: This study highlights significant demographic, clinical, and management differences between primary and secondary spontaneous pneumothorax, underscoring the importance of tailored treatment strategies to improve patient outcomes. Key findings include the impact of smoking status on recurrence risk and the necessity for individualized management plans, especially in SSP patients who exhibit higher rates of recurrence, longer hospital stays, and greater morbidity.
RESUMO
Although the usefulness of thoracoscopic surgery under local anesthesia for pneumothorax has been reported, there are some cases of failure. Therefore, it is important to share the various techniques and potential challenges associated with procedures performed under local anesthesia. A 79-year-old male, under monitoring for a left chronic pneumothorax, was newly diagnosed with a right pneumothorax. Chest computed tomography taken after thoracic drainage showed a poorly expanded right lung with severe adhesions and multiple bullae in the right lung, in addition to identifying a left pneumothorax. Although significant air leakage persisted, general anesthesia was deemed unsuitable, necessitating thoracoscopic surgery under local anesthesia. A fistula of approximately 1 × 1 cm was identified on the bulla wall, which was closed with 4-0 Prolene®sutures (Johnson&Johnson, New Jersey, United States), each reinforced with pledgets and covered with a polyglycolic acid sheet and fibrin glue. The patient was discharged on postoperative day six and no recurrence of pneumothorax was noted after discharge. Direct suture closure of the bulla wall under local anesthesia can be an alternative technique for the treatment of pneumothorax caused by large bulla collapse in patients at high risk for general anesthesia.
RESUMO
Introduction and importance: Birt-Hogg-Dube (BHD) is a rare genetic disorder that results from a mutation in the folliculin (FLCN) gene. Manifestations include pulmonary cysts, fibrofolliculomas, renal tumors, and pneumothoraces. Genetic testing can be used to confirm the diagnosis when suspected. BHD syndrome is diagnosed in patients with negative FLCN gene results using diagnostic criteria. Case presentation: A male in his 20s presented with recurrent pneumothoraces. A physical examination revealed bumps on his face and upper body. A chest computed tomography scan revealed cystic lesions. Blood tests, ESR, and CRP levels were unremarkable. Punch skin biopsy revealed fibrofolliculomas. Genetic testing for the FLCN mutation returned negative. His history, physical exam, imaging, and histopathology suggested BHD syndrome despite having a negative family history and genetic analysis. Eventually, the patient was diagnosed with FLCN gene-negative BHD syndrome. Clinical discussion: More than a hundred families have been identified to have BHD worldwide. There are a few cases in the literature describing patients phenotypically presenting with BHD despite having a negative genetic analysis. One study in Japan found 16 out of 157 individuals having a clinical presentation of BHD with no mutations. Also, decreased expression of the FLCN mRNA may lead to BHD. Conclusion: BHD syndrome can present with a negative FLCN gene mutation; however, patients must meet the known diagnostic criteria such as criteria made by Menko et al., Gupta et al., and Schmidt et al. in order to have a diagnosis of BHD syndrome. Also, a qualitative decrease of FLCN with the absence of mutations may also lead to BHD.
RESUMO
Duchene muscular dystrophy (DMD) is a genetic disorder primarily affecting males. It is characterized by progressive muscle tissue degeneration. Patients with DMD are at an increased risk of respiratory infections, including coronavirus disease 20019 (COVID-19), due to weakened respiratory muscles. We present a case of a young male with DMD who experienced recurrent pneumothorax 10 months after recovering from a COVID-19 infection. The patient required prompt medical intervention, including a chest tube, multiple surgeries, and mechanical pleurodesis. This case highlights the importance of recognizing recurring pneumothorax as a potential complication of COVID-19, particularly in patients with underlying neuromuscular disorders, as it is a medical emergency requiring prompt treatment to prevent respiratory compromise.
RESUMO
INTRODUCTION: Previous studies in 2018 and 2022 have suggested increasing inpatient burden of pneumothorax and widespread variation in management. Local trends have never been elucidated. Northumbria Healthcare NHS Foundation Trust (NHCT) has a well-established pleural service, serving just over 600,000. Thus, we set up a local retrospective study to look at trends in pneumothorax presentation, management strategies, length of stay, and recurrence. METHODS: A coding search for 'pneumothorax' was performed for all patients attending NHCT between 2010 and 2020 was performed with local Caldicott approval. A total of 1840 notes were analysed to exclude iatrogenic, traumatic, and paediatric events. After excluding those cases, 580 remained for further analysis, consisting of 183 primary pneumothoraces (PSP) and 397 secondary pneumothoraces (SSP). RESULTS: Median age for PSP was 26.5 years (IQR 17) with 69% male, and for SSP 68 years (IQR 11.5), 62% male; 23.5% of PSP and 8.6% of SSP were never smokers. The proportion of smokers and ex-smokers has not really changed over time: > 65% every year have been smokers or ex-smokers. Yearly pneumothorax incidence shows a downward trend for PSP but upwards for SSP. Median length of stay (LoS) for PSP was 2 days (IQR 2), and SSP 5 days (IQR 8), with a clear downward trend. From 2010 to 2015 > 50% PSP were managed with drain, but in 2019-2020 at least 50% managed conservatively, with a significant reduction in aspiration. Trends of recurrence for PSP are increasing, whereas for SSP is decreasing. Seventy-six (20 PSP, 56 SSP) went for surgery at the index time with 5.3% recurrence (20% recurrence in those without surgery). CONCLUSIONS: This is the first known analysis of pneumothorax trends in a large trust in the northeast of England. The data in this study have certain limitations, including the lack of information on the size of pneumothorax and frailty indicators that may influence the decision for conservative management. Additionally, there is a reliance on clinical coding, which can introduce potential inaccuracies, and not all patient notes were accessible for analysis. Updated larger datasets should help elucidate trends better.
RESUMO
Introduction: and importance: We reported a case of secondary spontaneous pneumothorax (SSP) in a 70-years-old male with acute exacerbation of COPD (AE COPD) managed with improvised chest tube drain (ICD). Case presentation: He presented with sudden onset breathlessness and oxygen saturation of 78%. With prolonged expiration on auscultation, he was treated as AE COPD with oxygen therapy, nebulization with albuterol/ipratropium, and injectable antibiotics and steroids. The patient was not improving with treatment on third day, and non-critical respiratory distress continued. Considering the alternative diagnosis, the chest X-ray was done which revealed right sided spontaneous pneumothorax and COPD. Due to his reluctancy to go to higher center for chest tube insertion during ongoing COVID-19 pandemic, we inserted ICD (intravenous set put in saline bottle) at our primary care. Following drainage, breathlessness improved and saturation increased. Then inpatient symptomatic treatment for COPD was continued for three more days. He was discharged on inhalers after fifth day and asked for follow up after 10 days. He came after 1 month and on repeat chest X-ray, his right sided pneumothorax resolved completely and COPD was in control with inhaled medications. There was no recurrence of pneumothorax in five months follow up. Clinical discussion: ICD is a safe, and an alternative option in resource limited setting. However, the guidelines recommend chest tube insertion as appropriate treatment. Conclusion: This would remind the physicians to anticipate the alternative possibility, and to re-examine those with AE COPD who are not improving as expected with oxygen and nebulization therapy.
RESUMO
Secondary spontaneous pneumothorax (SSP) is a medical emergency where the lung collapses in the presence of underlying chronic lung disease. It is the commonest cause of spontaneous pneumothorax and results in significant breathlessness, higher morbidity, mortality, and longer hospital admissions than with patients with pneumothoraces and no underlying lung disease. This article explores the current guidance, controversies, and recent advances in the management of this condition.
RESUMO
BACKGROUND: Digital drainage systems can continuously and numerically monitor air leakage, which may lead to a shorter duration of drainage and hospitalization; however, the usefulness of digital drainage systems compared to that of analog drainage systems for patients with primary or secondary spontaneous pneumothorax remains unclear. METHODS: This retrospective study included 108 patients with spontaneous pneumothorax who were successfully treated with chest drainage alone at our institution. We compared the clinical efficacy of digital and analog chest drainage systems. RESULTS: From the study population, 68 patients were diagnosed with primary and the other 40 with secondary spontaneous pneumothorax. The analog drainage system was used in 44 patients, and the digital drainage system in 64 patients. Among patients with primary spontaneous pneumothorax, the digital group had a significantly shorter duration of chest drainage than the analog group (median 2 vs. 4 days; p = 0.001), but there was no significant difference in those with secondary spontaneous pneumothorax. Additionally, the length and cost of hospitalization in the digital group were significantly lower than those in the analog group for both patients with primary and secondary spontaneous pneumothorax. There was no significant difference in recurrence within 1 week after chest tube removal between the two groups, neither among patients with primary nor among those with secondary pneumothorax. CONCLUSIONS: Digital drainage system may be better than analog drainage system for patients with primary spontaneous pneumothorax who need chest drainage, but further research is needed on drainage system selection for those with secondary disease.

We report a 69-year-old woman with spontaneous pneumothorax associated with cavitating pulmonary metastasis from breast cancer. She was treated for right breast cancer (invasive ductal carcinoma, ypT4bN1M0, stage IIIB) 2 years earlier, and was admitted for right pneumothorax and chest computed tomography, which showed multiple small cavitating lesions in bilateral lungs. The pneumothorax was treated conservatively with chest drainage, but subsequently recurred ipsilaterally. During video-assisted thoracic surgery, we detected small white nodules with visceral pleural rupture; therefore, we performed partial lung resection. The pathological findings revealed metastatic breast cancer with pleural invasion. Forty days later, ipsilateral pneumothorax recurred, and chemical pleurodesis was performed, which resolved the pneumothorax and prevented subsequent recurrence. Early diagnosis and definitive treatment, including pleurodesis, should be considered to prevent recurrence of spontaneous pneumothorax and improve patients' quality of life, even in patients with advanced malignancy.

Schistosomiasis is an endemic disease commonly found in areas of Africa and the Middle East. It is a prevalent parasitic infection in the southern region of Saudi Arabia and Yemen. The most common species found are Schistosoma mansoni and Schistosoma haematobium. Schistosomiasis can manifest in the urinary bladder, liver, and gastrointestinal system. The occurrence of the infection in the lungs is very rare and usually appears after years of initial infection. We report a case of a 23-year-old Yemeni male who presented to the emergency department complaining of sudden, right-sided chest pain with shortness of breath of one day. Examination and chest X-ray revealed the presence of pneumothorax, and a chest tube was inserted accordingly. As the pneumothorax did not resolve and a continuous air leak was present, the patient was taken to the operation theatre on suspicion of a fistula. The diagnostic procedure found the presence of bullae and patterns of inflammatory infection. A resected lung wedge revealed the presence of Schistosoma eggs, and schistosomiasis was diagnosed. In conclusion, spontaneous pneumothorax secondary to infection can present in young healthy males. Meanwhile, schistosomiasis infection must be kept in mind when dealing with patients coming from endemic areas even if they present with no recent visit to endemic areas.
