Foreign body in the esophagus is one of the most common emergencies and can occur at any age, with the elderly being the most common and young children the second most common. Because a large foreign body can temporarily stay in the lower pharynx or the narrowing of the esophageal inlet, it can block the airway and cause serious complications, even life-threatening, so it must be handled in a timely manner. The esophagus has three stenoses: 1, at the entrance of the esophagus; 2, at the crossing of the right bronchus; 3, at the esophagus through the diaphragmatic hiatus. Therefore, these three narrowings are the parts where foreign bodies tend to stay.
