Where Did the Lox 10 Tip Go? A Silent Iatrogenic Foreign Body: Case Report

Esophageal foreign bodies (FBs) are a common medical emergency, often requiring prompt diagnosis and intervention to prevent severe complications. While sharp objects like bones are frequently encountered, iatrogenic foreign bodies remain rare. We present a unique case of an elderly patient who inadvertently swallowed the dislodged tip of a Lignocaine spray applicator during an ENT procedure. Despite being asymptomatic, imaging confirmed the foreign body in the lower esophagus, which was successfully retrieved via flexible endoscopy. Our case highlights the importance of thorough assessment and imaging when foreign body ingestion is suspected, even in asymptomatic individuals. It also highlights the importance of careful equipment inspection, early recognition of potential device malfunctions, and timely intervention to ensure patient safety.
