Beyond diagnosis: a narrative review of the evolving therapeutic role of medical thoracoscopy in the management of pleural diseases.

Background and Objective: Medical thoracoscopy (MT) is an endoscopic technique performed by interventional pulmonologists with a favorable safety profile and few contraindications, providing diagnostic and therapeutic intervention in a single sitting. This narrative review was designed to summarize the therapeutic role of MT based on the latest results from the available literature. Methods: Pertinent literature published in English, relative to human studies, between 2010-2022 was searched in Medline/PubMed and Cochrane databases. Publications regarded as relevant were considered for inclusion in this review; additional references were added based on the authors' knowledge and judgment. The review considered population studies, meta-analyses, case series, and case reports. Key Content and Findings: MT has mostly been described and is currently used globally in the diagnostic approach to exudative pleural effusion of undetermined origin. Carefully evaluating the literature, it is clear that there is initial evidence to support the use of MT in the therapeutic approach of malignant pleural effusion, pneumothorax, empyema, and less frequently hemothorax and foreign body retrieval. Conclusions: MT is an effective procedure for treating the clinical entities presented in this document; it must be carried out in selected patients, managed in centers with high procedural expertise. Further evidence is needed to assess the optimal indications and appropriate patients' profiles for therapeutic MT. The endpoints of length of hospital stay, surgical referral, complications and mortality will have to be considered in future studies to validate it as a therapeutic intervention to be applied globally.

Pleural effusion aetiology, presentation, treatment and outcome in haematological diseases: a review.

BACKGROUND AND AIM: Pleural effusions (PE) can complicate the course of hematologic disorders (HD) and may arise in the form of malignant PE or as a consequence of non-neoplastic complications. While a certain amount of data has been published regarding infectious and iatrogenic HD-associated PE (HPE), no comprehensive review regarding the other types of HPE has ever been conducted. To address this issue, we performed a systematic review of the literature regarding HPE, focusing on the clinical and chemical characteristics of PE, therapeutic approaches and ì outcomes at the one-year follow-up. METHODS: We conducted our review according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. RESULTS: Overall, 283 manuscripts and 1216 cases were included. In summary, PE frequently signals an underlying HD, especially Hodgkin's lymphoma and IgG4-related disease; it mainly consists of exudate, although chylothorax is diagnosed in some cases. Although cytological examination has a discrete diagnostic yield, it is generally insufficient to render a definitive diagnosis; pleural biopsy remains an important diagnostic means in such cases. Invasive diagnostic procedures are not frequently performed because of an increased risk of haemorrhagic complications. The majority of PE are resolved by means of systemic therapy. When local treatments are attempted, the most frequently adopted procedures are evacuative thoracentesis and indwelling chest tube placement Conclusions: This review highlights the need for well-designed prospective studies comparing diagnostic means and therapeutic interventions for HPE to increase the quality of available data.  (www.actabiomedica.it).

Full medical treatment of COVID-19 associated large pneumothorax - A case report.

A 52-year-old man was re-admitted two weeks after recovering from severe COVD-19 following a 3-days history of cough and worsening shortness of breath. The chest radiograph showed a large right-sided pneumothorax. The first attempt at drainage, performed through a large bored tube, failed. Due to the large dimension of the pneumothorax, and the lung condition (extensive consolidation and diffuse bullous dystrophies), the only thoracic surgical approach prospected was a pneumonectomy. Willing to preserve the lung, the pulmonology team attempted a multi-phase medical-oriented strategy based on medical thoracoscopy. Therefore, the patient underwent 5 chest tube insertions, 2 talc pleurodesis, and an intrapleural blood patch. Air leakage resolution was progressively achieved, and the patient became asymptomatic.
