Endoscopic foreign body retrieval

Endoscopic foreign body retrieval refers to the removal of ingested objects from the esophagus, stomach and duodenum by endoscopic techniques. It does not involve surgery, but rather encompasses a variety of techniques employed through the gastroscope for grasping foreign bodies, manipulating them, and removing them while protecting the esophagus and trachea. It is of particular importance with children, people with mental illness, and prison inmates as these groups have a high rate of foreign body ingestion.

Commonly swallowed objects include coins, buttons, batteries, and small bones (such as fish bones), but can include more complex objects, such as eyeglasses, spoons, and toothbrushes (see image).
