[Thoracoscopic cutting needle biopsy].

We presented a new method of percutaneous cutting needle biopsy under the thoracoscope. Percutaneous cutting needles for lung tumor have been abandoned because the risk of hemorrhage, death, and pneumothorax is much greater with these instruments than the computed tomographic guided needle aspiration. On the other hand, thoracoscopic stapled lung wedge resection is easy to obtain a good sample for any lung disease, but should be needed two or three staples, and waste a time, in the case following lobectomy was needed for malignancy. This thoracoscopic cutting needle biopsy was easy to obtain a specimen for the frozened section diagnosis. Under the view of thoracoscope, percutaneous cutting needle biopsy is safety, saving the cost for staples and easy to control the bleeding from the lung. The indication of this thoracoscopic cutting needle biopsy is the case that could not obtain the precise diagnosis by the preoperative biopsy and imaging diagnosis might be suspicious a malignant tumor.
