The authors have developed a new special needle for transbronchofiberscopic aspiration biopsy in cases of lesions growing extrabronchially, especially in the hilum. The entire catheter with the needle extended is 111, 05cm in length, and the needle is 0.8cm in length with a width of 0.6mm and the angle of the needle tip bevel was set at 15°. When the bronchofiberscope reaches the target the catheter is inserted through the instrument channel of the Olympus BF-B2 or BF-B3 bronchofiberscope, and the needle is projected from the tip of the fiberscope and inserted into the lesion through the bronchial wall. In three cases of pulmonary disease which were not diagnosed by ordinary bronchofiberscopic procedures, transbronchofiberscopic needle aspiration biopsy was performed and yielded difinitive diagnosis in each case. Lung cancer and tuberculosis of the broncho-pulmonary lymph node were diagnosed in two cases which showed a well-defined nodule in the hilar region, and another case of lung cancer in right S2 was also diagnosed by this method.
