With the aid of a pulverizer, 2 gr talc was pulverized into 27 patients under local anesthesia, and into 42 patients under general anesthesia with one lung ventilation. Time of the operation ranged from 15 to 63 minutes (mean 42.3 minutes). There was no mortality. In the early postoperative period 2 patients constituted the morbidity: 2.8 %. During the early follw-up period a second pleurodesis was needed in 4 patients. Length of stay in hospital was between 2-8 days (mean 4.3 days). It is concluded that the application of 2 gr talc with the aid of videothoracoscopy in malign pleural effusion is an inexpensive procedure and reduces the length of stay.
