RESULTS: During this period, 87 medical thoracoscopic procedures were performed. Of these, 76 were diagnostic and 11 therapeutic. Mean age was 56.1 years for diagnostic and 61.3 for therapeutic indications. Main diagnostic indications were undiagnosed effusions (82.9%), empyema (7.9%) and recurrent pneumothorax (2.6%). Histopathology reports showed tuberculosis as the most common diagnosis (42.1%), followed by malignancy (39.5%) and chronic inflammation (7.9%). Rare diagnosis includes haemangioma of the lung. Therapeutic pleurodesis with talc (via thoracoscope) was done in 11 patients. Major indication was malignant pleural effusion (81.9%). Follow-up chest x-ray after one month showed no recurrence, indicating complete success.
