[Biopsies in pneumology: pleuroscopies-biopsies]

From already published cases and from those recently obtained (511 in all) the authors recollect their experience in lung biopsy : in 426 cases, a precise diagnosis was made by different methods. After having statistically analyzed the validity of pleuropulmonary multipuncture by comparison with pleuroscopy-biopsy, they underlined the necessity to use, in the latter technique, a flexible fibroscope, much used in bronchoscopy. They conclude in classifying the indications for each method in relation to the topography and the type of disease.
