Use of chest CT scan scoring system for diagnostic and therapeutic decision making in pleural effusion

摘要

Aim To investigate the usage of chest computed tomography (CT) scan score for improvement in diagnostic and treatment efficacy of repetitive pleural effusion. Methods CT scan scoring system was used as a part of diagnostic procedures in patients with repetitive pleural effusion. Patients with at least two pleurocentesis were included in the study. Chest and abdominal ultrasound, chest x-ray, bronchoscopy, biochemical, microbiological and cytological analysis of pleural fluid specimen were performed for all patients. Results In a two-year period (during 2017-2018) 79 patients were analysed, 27 (34.17%) female and 52 (65.82%) male patients. Malignant pleural diseases were confirmed in 32 cases (40.5%), nonmalignant pleural effusions in 38 (48.1 %) cases, and nine (11.4%) patients rested without exact cause of pleural effusion after two pleurocenteses. Binary regression model showed odds ratio of 1.314; CI 95% 1.119-1.543) (p=0.00088). Confirmed malignancies with pleural effusion were in high correlation with the number of points in CT scan score. Conclusion CT scan scoring system was helpful for diagnostic and treatment decision making in patients with repetitive pleural effusion.
