Endoscopic Foreign Body Retrieval - Non-invasive Testing

Non-invasive Testing

Prior to undertaking endoscopy, attempts should be made to locate the foreign body with x-rays or other non-invasive techniques. For radio-opaque objects, x-rays of the neck, chest and abdomen can be used to locate the foreign body and assist endoscopy. Alternative approaches, including the use of metal detectors, have also been described.

X-rays are also useful for identifying the type of foreign body ingested and complications of foreign body ingestion, including mediastinitis and perforation of the esophagus.
