Pulmonary Wedge Resection for a Dental Instrument Retained in the Bronchus for a Long Time Period：Report of a Case

はじめに　無症候性の気管支異物は，長期間にわたり認識されずに経過することがあり，発見時には気管支鏡下での摘出が困難なことがある．われわれは歯科用器材を肺部分切除により摘出した1例を経験したので報告する．

It is often difficult to remove long-standing foreign bodies by bronchoscopy. The patient was a 57-year-old woman who accidentally aspirated a dental instrument during dental treatment. Two years later, an abnormal shadow was noted on chest imaging, and she was referred to our hospital. Chest computed tomography （CT） revealed a 2-cm foreign body in the left lower lobe. Bronchoscopy was performed, but the foreign body could not be removed. Thoracoscopic partial resection of the left lower lobe was undertaken for removal of the foreign body.
