OBJECTIVE: To assess the diagnostic value of video-assisted thoracoscopic surgery in exudative pleural effusions, and to evaluated the frequency of malignancy development with long term follow-up of patients defined as nonspecific pleuritis after surgery. . METHODS: The retrospective study was conducted at Yedikule Chest Diseases and Thoracic Surgery Training and Research Hospital, Istanbul, Turkey, and comprised data of patients with undiagnosed exudative pleural effusions seen between January 2008 and December 2013. Data related to clinical, radiological, thoracoscopical, histopathological and follow-up periods were obtained from the hospital records. SPSS 15 was used for data analysis. RESULTS: Of the 229 patients, 145(63.3%) were males and 84(36.7%) were females. The overall mean age was 54.5 }15.1 years. Malignancy was found in 84 (36.6%) patients, and tuberculosis in 26(11.4%). The remaining 119(52%) patients had nonspecific pleuritis and their mean follow-up period was 29.2}27.1 months (range: 1-103 months). Video-assisted thoracoscopic surgery was repeated in 3(2.52%) patients in the 1st, 4th and 16th months of followup period due to the recurrence of pleural effusion. Tuberculosis and mesothelioma were diagnosed in 1(0.8%) and 2(1.7%) cases, respectively. CONCLUSIONS: Video-assisted thoracoscopic surgery was found to be a valuable diagnostic procedure in patients with undiagnosed exudative pleural effusion.
