Emergency And Acute Medicine – Foreign Body, Esophageal
Basics Description
Esophageal foreign bodies typically lodge at physiologic narrowing points: the cricopharyngeal muscle at C6 (≈63%, most common), the level of the aortic arch at T4 (≈10%), and the gastroesophageal junction at T11 (≈20%). Approximately 90% of ingested foreign bodies pass spontaneously, 10–20% require endoscopic removal, and fewer than 1% require surgical intervention.
Etiology
In adults and adolescents, food boluses and bones are most common. Risk is increased in edentulous patients, intoxicated individuals, and those with underlying esophageal pathology such as Schatzki B-rings or peptic strictures.
Pediatric ingestions account for about 80% of cases, most commonly between 6 months and 6 years of age, especially under 2 years. Coins are the most frequent pediatric esophageal foreign body. Additional pediatric constriction sites include the thoracic inlet (T1) and the tracheal bifurcation (T6).
Diagnosis Signs And Symptoms
Acute ingestion may cause dysphagia, odynophagia, drooling, gagging, choking, retching, blood-stained saliva, or chest discomfort. Chronically retained foreign bodies often present with respiratory symptoms such as cough, stridor, or hoarseness due to paraesophageal swelling compressing the airway.
Sharp object ingestion carries a 15–35% risk of esophageal perforation, with findings including neck swelling, erythema, crepitus, chest pain, pleurisy, or peritonitis.
Adults usually provide a clear history and often present within 24 hours. Children may be asymptomatic or present with drooling, refusal to eat, unexplained gagging, cough, wheeze, or choking; history may be unclear if ingestion was unwitnessed.
Essential Workup
Obtain a detailed history regarding the type, size, and timing of ingestion. Physical examination should assess for obstruction, perforation, aspiration, hemorrhage, and airway compromise, including evaluation of the neck, chest, lungs, abdomen, and oropharynx.
Diagnosis Tests And Interpretation
Biplane chest and neck radiographs are used to localize radiopaque foreign bodies; esophageal objects often align in the coronal plane. Signs of perforation include retropharyngeal air, cervical soft tissue air, or pneumomediastinum. Many bones and food boluses are radiolucent.
CT scanning is increasingly used for radiolucent objects and to detect perforation or infection.
Endoscopy is the diagnostic and therapeutic modality of choice, allowing direct visualization, removal, and evaluation of underlying mucosal pathology.
Differential Diagnosis
Globus sensation, esophagitis, esophageal mucosal irritation, croup, epiglottitis, upper respiratory tract infection, and retropharyngeal abscess.
Treatment
Prehospital care prioritizes airway protection and aspiration prevention; emetics and cathartics are contraindicated.
In the emergency department, airway, breathing, and circulation take priority. Direct laryngoscopy may remove very proximal objects.
Urgent endoscopy is indicated for sharp or elongated objects (>6 cm long or >2.5 cm wide), irregular edges, multiple objects (especially magnets), suspected perforation, airway compromise, food bolus with complete obstruction, foreign bodies present for more than 24 hours, or coins lodged at the cricopharyngeus in children.
Asymptomatic patients with smooth objects in the distal esophagus (excluding button batteries) may be observed for up to 24 hours.
Glucagon may be considered for recent distal food bolus impaction but is less effective with strictures and is falling out of favor.
Fluoroscopically guided Foley catheter extraction or bougienage may be used in selected cases by experienced providers.
Button batteries require emergent removal due to rapid liquefaction necrosis. Magnets require early GI or surgical consultation. Surgical intervention is reserved for failed endoscopic removal or complications.
Medication
Glucagon 1–2 mg IV may be used selectively for distal food bolus impaction after assessing for contraindications.
Follow Up Disposition
Admission is required for airway compromise, perforation, significant bleeding, migration of the foreign body, or failed removal.
Discharge is appropriate for asymptomatic patients after removal or confirmed passage into the stomach, with re-evaluation within 12–24 hours if distal esophageal objects are observed.
Follow Up Recommendations
GI referral is recommended when underlying esophageal pathology is suspected or for follow-up after complicated ingestions.
Key Practice Insights And Common Pitfalls
Always localize radiopaque foreign bodies with imaging and maintain a high index of suspicion for esophageal perforation, particularly with sharp objects or delayed presentation.
