Endoscopic resection of an endobronchial hypernephroma metastasis using a polypectomy snare.

A 69 yr old male patient developed an acute respiratory distress. The emergency bronchoscopic examination showed a polypoid tumour obstructing the left main bronchus. A snare used for colorectal polypectomy was introduced through the bronchofibrescope to remove the tumour. The patient then dramatically improved. No side effects were observed. Histopathological examination showed metastasis from a hypernephroma. This simple technique is useful for bronchial deobstruction, when the tumour is accessible with a snare.
