Differentiation between hydropneumothorax and destroyed lung by thoracoscopy with a fiberoptic bronchoscope

In a 39-year-old man radiologic examination could not distinguish definitely between a hydropneumothorax and total destruction of one lung. Introduction of a fiberoptic bronchoscope through the opening for the chest drainage tube permitted direct inspection of the air space. A definite diagnosis of a destroyed lung was made, permitting appropriate modification of the treatment.
