Comparing VATS surgery and drainage for treating pleural empyema

Intrapleural Fibrinolysis and DNase Versus VATS for the Treatment of Pleural Empyema: a Randomized, Controlled Trial

Not applicable Interventional Aarhus University Hospital · NCT04095676

This study is testing whether a type of surgery called VATS works better than standard drainage methods for helping patients with pleural empyema feel better and recover their lung function.

What this trial studies

This clinical trial aims to evaluate the effectiveness of Video Assisted Thoracoscopic Surgery (VATS) compared to standard drainage methods for patients with pleural empyema, particularly in stages II and III of the disease. The study will involve randomizing participants to receive either VATS or drainage with intrapleural fibrinolytic therapy. The goal is to determine which treatment provides better outcomes in terms of infection removal and lung expansion. The trial is being conducted at multiple hospitals in Denmark, focusing on patients who have been hospitalized for acute pleural infections.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18 and older who have been hospitalized with a diagnosis of community-acquired pleural infection.

Not a fit: Patients who are pregnant, breastfeeding, terminally ill, or have had previous intrathoracic surgery within the last year may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved treatment options for patients with pleural empyema, potentially reducing morbidity and mortality rates.

How similar studies have performed: Previous studies have shown positive effects of combining fibrinolytic therapy with DNase, but the comparison of VATS to drainage in this context is still under clinical evaluation.
