[Video-assisted thoracoscopic surgery (VATS) for the management of parapneumonic pleural empyema]

Parapneumonic pleural empyema has been classified by international societies and by pleural diseases experts into different stages and classes. While the American Thoracic Society (ATS) classification is based on the natural course of the disease, Light has classified pleural empyema according to radiological, physical and biochemical characteristics, and the American College of Chest Physicians (ACCP) has categorised patients with pleural empyema according to the risk of a poor outcome. According to these classifications, the management of the pleural empyema is based on the stage of the disease. The recommended treatment options in (ATS) stage I disease (Light classes I-III, ACCP categories I and II) are therapeutic thoracentesis or tube thoracostomy and antibiotics when necessary. In (ATS) stage II disease (Light classes IV-VI, ACCP category III), thoracoscopy (VATS) is the treatment of choice because it has a higher efficacy than treatment strategies that utilise tube thoracostomy or catheter-directed fibrinolytic therapy alone, whereas in (ATS) stage III disease (Light class VII, ACCP category IV), decortication via thoracoscopy or thoracotomy is the treatment of choice.
