In patients suspected of FB or caustic substance ingestion is mandatory to verify both airway permeability and related complications. Anamnesis will give information regarding features of FB or caustic substances ingested. Radiologic test can provide FB location data as well as complication data. «Gold standard» for the diagnosis of caustic lesions is the gastroscopy. Endoscopic removal has to performed in 6 first hours in the following cases: complete esophageal obstruction, batteries placed in esophagus and stabbing/cutting FB. In remaining cases, depending on FB type and location, endoscopy can be carried out among 24-48hours. In cases of body-packers ingestion or perforation suspicion, endoscopy retrieve is contraindicated. Provoked vomiting, attempts to neutralize or to dilute the corrosive agent, are contraindicated in caustic agent ingestion. Therapeutic strategy varies according with endoscopic findings (Zargar's classification).
