In the combined procedure group, a PleurxTM tunnelled catheter will be inserted under ultrasound guidance. As this procedure will be done concurrently with thoracoscopy, there is no estimated increase in endoscopy time. If either group of patients is found to have no gross evidence of malignancy at the time of thoracoscopy (ie. empyemas or tuberculous pleurisy), then they will be withdrawn from the study and notified appropriately.
