Cuerpo extraño incidental en tracto gastrointestinal. Reporte de tres casos y revisión de la literatura Incidental foreign body in the gastrointestinal tract. Report of three cases and literature review

Foreign body ingestion is a common condition in the emergency department. Although most objects get away without symptoms, events occur depending of their location and characteristics or may go unnoticed and later cause severe complications that threaten the patient's life. We report three cases of foreign bodies identifi ed during upper gastrointestinal endoscopy as an incidental fi nding and a review of the epidemiology of this con- dition, and the variety of clinical presentations depending on the organ involved, secondary complications and diagnostic approaches. Finally, we propose a fl ow chart diagnosis and treatment that unifi es those proposed in the literature.
