INTRODUCTION
Pulmonary abscess is a complication of lung infection with localized necrosis and purulent cavity formation. Pulmonary abscesses are typically managed using antibiotic therapy with anatomic surgical resection reserved as a rescue. Percutaneous drainage is considered relatively contraindicated in some centers due to perceived risk of bronchopleural fistula. However, drain placement has been frequently employed at our institution. The purpose of this study was to review and describe our longitudinal experience.
METHODS
Medical records of children diagnosed with lung abscess and treated with percutaneous drainage from 2005 through 2023 were reviewed. Patient clinical parameters, follow-up imaging, and clinical outcomes were evaluated.
RESULTS
Percutaneous drainage (n = 24) or aspiration alone (n = 4) under imaging guidance was performed by interventional radiologists for 28 children with lung abscesses. A single catheter (8-12 Fr) was deployed in the pulmonary abscess cavity and remained for a median of 6 days (IQR: 6-8 days). The median hospital stay was 10 days (IQR: 8.8-14.8 days). The technical success rate for percutaneous drainage or aspiration of primary pulmonary abscesses was 100% (26/26). Two children were later diagnosed with secondarily infected congenital pulmonary airway malformations that were both successfully drained and ultimately surgically resected. The abscess cavities resolved in all patients and catheters were removed upon clinical, radiographic, and laboratory improvement. Complications included the presence of two bronchopleural fistula, both of which were treated with immediate pleural drain placement.
CONCLUSION
Percutaneous drainage of pulmonary abscesses is an effective therapeutic option in children and can be considered alongside antibiotics as part of the initial treatment for pulmonary abscesses. Bronchopleural fistula can occur, but at a lower frequency than previously reported.

Anaesthetists may be required to work in hybrid theatres for procedures using fluoroscopic imaging. Adequate knowledge of fluoroscopic images allows prompt and effective emergency management of complications which arise during procedures. Here, we present a case of severe hypotension and hypoxia occurring shortly after induction of anaesthesia. Atelectasis was mistaken for a pneumothorax due to misinterpretation of fluoroscopic imaging, which demonstrated a dark pleural cavity peripheral to a partially collapsed left lung, leading to an incorrect diagnosis. This case highlights the importance of understanding greyscale inversion in fluoroscopy.

BACKGROUND
Lung cancer is the second most diagnosed cancer and the leading cause of cancer deaths worldwide. Surgical lung resection is the best treatment modality in the early stages of lung cancer as well as in some locally advanced cases. Postoperative air leak is one of the most common complications after pulmonary resection with incidence ranging between 20 and 33%. The majority of air leaks seal, within 5 days after surgery, on their own by conservative management. However, at least 5% of patients still have prolonged air coming out from the residual lung at discharge. This report describes the management of a thin lady with right lung cancer who underwent a right lower lobectomy and then suffered from a delayed air leak 7 weeks after surgery and required extensive thoracic and general surgery collaboration.
CASE PRESENTATION
A 72-year-old heavy smoker female patient diagnosed with stage I lung cancer underwent right robotic-assisted thoracoscopic surgery converted to thoracotomy because of a fused fissure, right lower lobectomy, and mediastinal lymphadenectomy presented with delayed air leak 49 days after surgery. VATS decortication and mechanical pleurodesis were done 2 weeks after unsuccessful conservative treatment. Still, the lung failed to expand four weeks later so the patient was sent to surgery; she is underweight (BMI of 18) with not many options for a big flap to fill the chest cavity empty space. Accordingly; the decision was to use multiple pedicle flaps; omentum, intercostal muscle, and serratus anterior muscle to cover the bronchopleural fistulas and fill the pleural space in addition to mechanical and chemical pleurodesis. Full expansion of the lung was obtained. The patient was discharged on Post-Operative day 5 without remnant pneumothorax.
CONCLUSIONS
Air leaks After lobectomy usually presents directly postoperatively; various management options are available ranging from conservative and minimally invasive to major operative treatment. We presented what we believe was unusual delayed bronchopleural fistula post-lobectomy in a thin lady which demonstrates clearly how a delayed air leak was detected and how collaborative efforts were crucial for delivering high-quality, safe, and patient-centered care till treated and complete recovery.

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.

INTRODUCTION
Pleural effusion is a medical condition where an excessive amount of fluid accumulates in the pleural space. This can be caused by inflammation or malignant growth in the body. Doctors use medical thoracoscopy for both diagnostic and therapeutic purposes. This technique allows them to view the internal pleural surfaces and take biopsies of any abnormal lesions within the pleural cavity.
OBJECTIVE
This work aimed to evaluate the diagnostic value of pleuroscopy in patients with undiagnosed exudative pleural effusion.
PATIENTS AND METHODS
A study was conducted on 61 patients who had undiagnosed exudative pleural effusion and were admitted to the chest department at the cardiothoracic unit of the Minia University Hospital. All patients provided written consent and underwent a complete history and clinical examination. Standard laboratory tests, including routine liver and kidney function tests, a complete blood count, and a coagulation profile, were conducted on all patients, along with chest X-rays. If necessary, a chest CT scan was also performed. Diagnostic thoracentesis was done, and the pleural fluid was analyzed for sugar, protein, and lactate dehydrogenase and sent for bacteriological analysis (Gram stain, culture, and acid-fast bacilli smear) and cytopathological examination. Medical thoracoscopy was performed in cases where an etiological diagnosis was not established.
RESULTS
A total of 61 patients with undiagnosed exudative pleural effusions were included. A definitive etiological diagnosis was reached in 58 (95%) patients. In 47 (77%) of the studied group, malignant etiology was confirmed; nine (14.8%) had tuberculous pleurisy, one (1.6%) had empyema, and one (1.6%) had inflammatory/autoimmune pleurisy. A definite diagnosis was not reached in three (5%) patients. The malignant pathology was caused by bronchogenic carcinoma in 20 (42.5%) cases, malignant mesothelioma in 10 (21.3%) cases, metastatic malignant deposits from other organs in six (12.7%) cases, and lymphoma in three (6.5%) cases. No serious adverse events related to the procedure were recorded. The most common minor complications were transient chest pain in 34 (55.7%) patients, followed by surgical emphysema in 10 (16.4%) patients.
CONCLUSION
Pleuroscopy is an effective diagnostic tool for identifying the cause of pleural effusion when it is unclear. It is a minimally invasive and straightforward procedure associated with high diagnostic accuracy and low complication rates.

Pleuroperitoneal communication occurs when ascites moves from the abdominal cavity to the pleural cavity via a diaphragmatic fistula. Managing large pleural fluid volumes is challenging, often requiring an operation. Identifying small diaphragmatic fistulas during the operation can be problematic, but ensuring their detection improves outcomes. This video tutorial presents a recent empirical case in which we successfully identified and closed a pleuroperitoneal contact using a thoracoscopic surgical procedure aided by indocyanine green fluorescence imaging. The patient, a 66-year-old woman, was hospitalized due to acute dyspnoea from a right thoracic pleural effusion during hepatic ascites treatment for cirrhosis. Because ascites decreased with pleural fluid drainage, surgical intervention was considered due to suspicion of a pleuroperitoneal connection. During the operation, indocyanine green was injected intraperitoneally, and near-infrared fluorescence-guided thoracoscopy pinpointed the location of the diaphragmatic fistula. The fistula was sutured and reinforced with a polyglycolic acid sheet and fibrin glue. Detecting the fistula intraoperatively is crucial to prevent recurrence, and the indocyanine green fluorescence method is a safe and effective technique for detecting small fistulas.

BACKGROUND
Cystic lung cancer, a special type of lung cancer, has been paid more and more attention. The most common pathological type of cystic lung cancer is adenocarcinoma. The invasiveness of cystic lung adenocarcinoma is vital for the selection of clinical treatment and prognosis. The aim of this study is to analyze the multiple clinical features of cystic lung adenocarcinoma, explore the independent risk factors of its invasiveness, and establish a risk prediction model.
METHODS
A total of 129 cases of cystic lung adenocarcinoma admitted to the Department of Thoracic Surgery of the First Affiliated Hospital of Nanjing Medical University from January 2021 to July 2022 were retrospectively analyzed and divided into pre-invasive group [atypical adenomatous hyperplasia (AAH), adenocarcinoma in situ (AIS) and minimally invasive adenocarcinoma (MIA)] and invasive group [invasive adenocarcinoma (IAC)] according to pathological findings. There were 47 cases in the pre-invasive group, including 19 males and 28 females, with an average age of (51.23±14.96) years. There were 82 cases in the invasive group, including 60 males and 22 females, with an average age of (61.27±11.74) years. Multiple clinical features of the two groups were collected, including baseline data, imaging data and tumor markers. Univariate analysis, LASSO regression and multivariate Logistic regression analysis were used to screen out the independent risk factors of the invasiveness of cystic lung adenocarcinoma, and the risk prediction model was established.
RESULTS
In univariate analysis, age, gender, smoking history, history of emphysema, neuron-specific enolase (NSE), number of cystic airspaces, lesion diameter, cystic cavity diameter, nodule diameter, solid components diameter, cyst wall nodule, smoothness of cyst wall, shape of cystic airspace, lobulation, short burr sign, pleural retraction, vascular penetration and bronchial penetration were statistically different between the pre-invasive group and invasive groups (P<0.05). The above variables were processed by LASSO regression dimensionality reduction and screened as follows: age, gender, smoking history, NSE, number of cystic airspaces, lesion diameter, cystic cavity diameter, cyst wall nodule, smoothness of cyst wall and lobulation. Then the above variables were included in multivariate Logistic regression analysis. Cyst wall nodule (P=0.035) and lobulation (P=0.001) were found to be independent risk factors for the invasiveness of cystic lung adenocarcinoma (P<0.05). The prediction model was established as follows: P=e^x/(1+e^x), x=-7.927+1.476* cyst wall nodule+2.407* lobulation, and area under the curve (AUC) was 0.950.
CONCLUSIONS
Cyst wall nodule and lobulation are independent risk factors for the invasiveness of cystic lung adenocarcinoma, which have certain guiding significance for the prediction of the invasiveness of cystic lung adenocarcinoma.

Mechanical ventilation contributes to the morbidity and mortality of patients in intensive care, likely through the exacerbation and dissemination of inflammation. Despite the proximity of the pleural cavity to the lungs and exposure to physical forces, little attention has been paid to its potential as an inflammatory source during ventilation. Here, we investigate the pleural cavity as a novel site of inflammation during ventilator-induced lung injury. Mice were subjected to low or high tidal volume ventilation strategies for up to 3 hours. Ventilation with a high tidal volume significantly increased cytokine and total protein levels in BAL and pleural lavage fluid. In contrast, acid aspiration, explored as an alternative model of injury, only promoted intraalveolar inflammation, with no effect on the pleural space. Resident pleural macrophages demonstrated enhanced activation after injurious ventilation, including upregulated ICAM-1 and IL-1β expression, and the release of extracellular vesicles. ventilation and stretch of pleural mesothelial cells promoted ATP secretion, whereas purinergic receptor inhibition substantially attenuated extracellular vesicles and cytokine levels in the pleural space. Finally, labeled protein rapidly translocated from the pleural cavity into the circulation during high tidal volume ventilation, to a significantly greater extent than that of protein translocation from the alveolar space. Overall, we conclude that injurious ventilation induces pleural cavity inflammation mediated through purinergic pathway signaling and likely enhances the dissemination of mediators into the vasculature. This previously unidentified consequence of mechanical ventilation potentially implicates the pleural space as a focus of research and novel avenue for intervention in critical care.

INTRODUCTION
Pancreaticopleural fistula is a rare complication most associated with alcohol-induced chronic pancreatitis. This usually presents with chest symptoms instead of abdominal ones. Diagnosis requires a high index of suspicion in patients with pancreatitis and persistent pleural effusions.
PRESENTATION OF CASE
We present a case of an 81-years-old man admitted in the emergency department with a one week complaints of productive cough, fever, dyspnea and left-side chest pain. The chest X-ray revealed a moderated-volume left-side pleural effusion. The pleural fluid analysis was consistent with an exsudative pleural effusion with high levels of amylase. The thoracoabdominal CT raised the suspicion of a pancreaticopleural fistula, confirmed by ERCP. A pancreatic main duct stenting was performed with good results. The patient was discharged asymptomatic after 18 days of hospitalization.
DISCUSSION
Because of PPF insidious presentation it poses a great number of differential diagnosis, so pleural fluid analysis is of paramount importance with high levels of amylase confirming the diagnosis. MRCP and ERCP may establish the fistulous tract between the pancreatic duct and the pleural cavity, with the latter being also therapeutic.
CONCLUSION
The rarity of this complication related to pancreatitis and the seldomly presence of abdominal pain in contrast with chest symptoms poses a diagnostic challenge.
