A Case of Foreign Body (The Obturator of a Lidocaine Spray Nozzle in the Respiratory Tract, Caused by Pretreatment for Upper Gastrointestinal Endoscopy

Abstract

A 79-year-old woman was admitted to our hospital for further examination of a tracheal tumor shadow on chest computed tomograpy. Fiberoptic bronchoscopy revealed a tracheal tumor and a metallic foreign body in the trachea and right main bronchus. We removed the foreign body successfully by conventional forceps under fiberoptic bronchoscopy. The foreign body was an obturator of lidocaine spray nozzle, and was considered to have been caused by pharyngeal analgesia using a lidocaine spray before upper gastrointestinal endoscopy.
