From May 1983 to June 1985 the authors performed a thoracoscopy as a diagnostic and therapeutic objective in 83 patients with chronic recurrent pleurisy; amongst these patients, 69 had know intra or extra thoracic cancer and the other 14 presented with an isolated pleurisy. Eight other patients had pleural carcinomatosis proven by needle biopsy and had pleural talc introduced by thoracoscopy. The examination was performed under local anaesthesia with neuroleptanalgesia; a rigid 7 mm diameter thoracoscope was used; the biopsies were performed uniquely on the parietal pleura using tropical forceps. The outcome was uncomplicated with no deaths nor any serious complications due to the method. The sensitivity of the pleural biopsy was 91.5% or 76 positive biopsies out of 83. 73 biopsies were metastatic and 3 were tuberculous pleurisies. The macroscopic appearance was strongly suggestive of malignancy in 78 patients and appeared inflammatory in 13, of whom 9 cases were positive on biopsy. The authors performed a pleural talcage in every case; a lasting pleural adhesion was obtained in 66 patients but regrettably there were 14 failures, the effusion recurring after removal of the drain. The authors stress the reduced number of incidents of pleural effusion, which confirms the good tolerance of pleural endoscopy.
