A fragment of a fractured tracheostomy tube as a foreign body in the bronchus is very unusual. We report an 18-year old male with Hunter's syndrome who presented with fever and bronchorrhea. He had worn a tracheostomy tube for 2 years without its being removed for cleaning. Chest X-ray showed an opaque foreign body in the right main bronchus which was removed through a flexible bronchoscope and found to be a piece of the broken edge of the outer cannula of a tracheostomy tube. We suggest regular examination of tracheostomy tubes for signs of wear-and-tear and recommend their periodic renewal before they become worn out.
气管切开插管断裂后的碎片作为支气管内异物非常罕见。我们报告一名18岁患有亨特综合征的男性，他出现发热和支气管溢液症状。他佩戴气管切开插管2年未取出清洗。胸部X光显示右主支气管内有一不透光异物，通过可弯曲支气管镜取出后发现是气管切开插管外管断端的一块碎片。我们建议定期检查气管切开插管是否有磨损迹象，并建议在其磨损之前定期更换。
