Abstract:
This report presents the case of successful removal of a distally located foreign body using a guide sheath (GS). A 78-year-old man was brought for x-ray examination after a dental treatment at a local clinic. A dental instrument, a diamond bur, was missing after the treatment. The chest x-ray revealed a needle-like instrument located in the peripheral right middle lobe. The distally located foreign body was removed with a flexible bronchoscope using a curette and a biopsy forceps placed through a GS. This is the first report of use of a GS to remove a foreign body.
