Abstract

Background: Currently, there are many methods applied to diagnose the causes of pleural effusion (PE). Blind pleural biopsy is an effective method in the diagnosis of the pleural effusion causes. Objective: To describe the clinical and imaging characteristics and analyze the diagnostic value of blind pleural biopsy in the patients with exudative pleural effusion at Can Tho Central General Hospital and Can Tho Tuberculosis and Lung Disease Hospital. Materials and methods: Prospective, descriptive and analytical cross-sectional study on 100 the patients with exudative pleural effusion at Can Tho Central General Hospital and Can Tho Tuberculosis and Lung Disease Hospital since 2023 to 2024. Results: Among 100 patients, 64% male and 36% female, male/female ratio was 1.8. The older the age, the higher the percentage (≤50 years old was 13%; 51-60 years old was 29%; ≥65 years old was 58%). Dry cough (58%), coughing up phlegm (20%), hemoptysis (3%), chest pain (88%), dyspnea (50%), weight loss (17%), fever (21%). Pleural effusion sites were right (57%), left (40%) and bilateral (3%). Pleural effusion amount was small (8%), moderate (51%), and large (41%). The pleural effusion causes diagnosed by blind pleural biopsy was rated at 73% of all cases. In the Tuberculosis Disease patients, the Sensitivity (Se): 96.9%; Specificity (Sp): 100%; Positive predictive value (PPV): 100%; Negative predictive value (NPV): 98.6%. In the diagnosis of cancer disease, the sensitivity was: 96.9%; Specificity: 100%; Positive predictive value: 100%; Negative predictive value: 98.6%. Conclusion: Blind pleural biopsy is highly effective in the diagnosis of the exudative pleural effusion causes.
