Esophageal diverticulum arising from a prolonged retained esophageal foreign body.

Esophageal foreign body impaction (EFBI) is a rare condition in childhood which needs urgent removal. However, if left untreated, its chronic impaction may lead to serious secondary complications. Symptoms associated with chronic EFBI are attributed to airway disease or gastroesophageal reflux, which further delays definitive diagnosis and management. We present a girl with ingestion of a bottle cap diaphragm that was embedded in her esophagus resulting in esophageal narrowing and a secondary diverticulum formation. As the disk was unable to be removed using standard grasping forceps, the authors used an injector needle to impale the disk and successfully removed it without any complications.
