Background: Medical thoracoscopy (MT) or pleuroscopy is a procedure performed to diagnose and treat malignant and benign pleural diseases. Totally 2752 pleuroscopies executed in 1984–2013 in our center were considered in this study. Methods: A retrospective observational study was performed. Observational time was divided into six series of 5 years. We calculated MT diagnostic yield and analyzed trends of main diseases diagnosed along the time. Results: Along the 30 years population became progressively older. Number of pleuroscopies firstly increased, then stabilized and decreased in the last 5 years. The overall diagnostic yield of MT was 71%, increasing from 57% to 79%. The diagnostic yield was significantly higher in the presence of monolateral pleural effusion. Cancer represented more than half of diagnosis; tuberculosis was the most common nonneoplastic disease. The frequency of all cancers, mesothelioma, and lung cancer increased through the time; tuberculosis first decreased and then increased. All specimens resulted appropriate during the last 25 years. Conclusion: MT has a great diagnostic yield that can be improved by practice, permitting to achieve a specific histological diagnosis in about 80% of patients. Our experience demonstrates that the accurate selection of the patients undergoing to MT is very important to reach these results.
