In children, tracheal compression and stridor suggest a large foreign body at the upper esophageal sphincter.
In cooperative patients, indirect laryngoscopy or fiberoptic nasopharyngoscopy provides better information than a direct examination. The most common cause of GI foreign bodies in adults involves food that does not pass through the esophagus because of underlying mechanical problems.
Dysphagia is the norm in adults with esophageal foreign bodies. If the obstruction is complete, an inability to handle secretions is common.
