OPTIMAL TIMING OF VIDEO THORACOSCOPIC INTERVENTIONS DEPENDING ON THE DURATION OF ACUTE PLEURAL EMPYEMA

Abstract. The aim of our study: analyze the nature of pleural changes and determine the optimal timing of interventions using VTS depending on the duration of acute pleural empyema. Material and methods. The nature of changes in the parietal and visceral pleura of 249 patients with acute pleural empyema treated with video thoracoscopic interventions was evaluated. Patients were divided into 5 groups depending on the duration of the disease. Results. It was determined that fibrinous accumulations in acute pleural empyema are replaced by cavity fragmenting formations after 6 weeks from the onset of the disease. The cessation of purulent exudate accumulation and the duration of pleural drainage after thoracoscopy depends on the duration of the disease at the time of thoracoscopy, as evidenced by the duration of pleural drainage in the period up to one month – 8 days from the onset of the disease, up to two months – 15 days, and after 8 weeks of duration – reached 20 days. Conclusions. Inflammatory changes in the pleura in the form of fibrin deposits and cavity fragmentation in pleural empyema increase rapidly enough, the possibility of its effective rehabilitation during thoracoscopy without open surgical interventions is limited to 6 weeks from the onset of the disease.
