[Bronchofibroscopy. 6 questions, 6 fundamental answers].

The authors report the aims, methods, techniques of sampling and the tolerance of broncho-fibroscopy, correlating literature and their personal experience of a thousand examinations. They consider it a very simple examination which without any inconvenience can be used in very serious cases as well as for out-patients. They insist on the technique of biopsy and directed aspiration and demonstrate that with experience the yield of the method can be improved. They conclude by saying that a histo-cytological diagnosis can be made in 95% of cases of bronchial cancers. In their experience, tolerance to this examination is always very good.
