Pleuroscopy in patients with pleural effusion and pleural masses.

We performed diagnostic pleuroscopy in 66 patients with pleural effusion and in 14 with pleural masses. The findings were diagnostic in 76 patients (95%). Pleural metastases were found in 63 patients, primary pleural or lung tumor in 5, and less common findings in the remainder. Only 1 minor complication occurred, and there were no deaths. Malignant pleural effusion causing dyspnea was managed successfully by talc insufflation under direct vision in 31 of 35 patients. Talc also was used with equal success and without complications in management of recurrent pneumothorax. We conclude that pleuroscopy is a useful diagnostic and therapeutic procedure. It is simple and well tolerated, has a diagnostic yield of 95%, and is virtually free from complications. It provides the best way of insufflating talc for pleurodesis.
