Background

  • Pediatric foreign body refers to the ingestion, aspiration, or insertion of a foreign object by a child, most commonly occurring in children aged 6 months to 3 years.[1]
  • Foreign bodies may lodge in the airway, esophagus, gastrointestinal tract, ear, nose, or vagina.


  • Foreign body ingestion and aspiration are among the most common pediatric emergencies
  • Peak incidence is between 1 and 3 years of age[2]
  • Male-to-female ratio is approximately 2:1[3]
  • Ingestion accounts for the majority of cases
    • Coins are the most commonly ingested foreign body in the United States[4]
    • Most ingested objects (80-90%) pass spontaneously through the GI tract
  • Aspiration is responsible for approximately 7% of accidental deaths in children under 3 years of age[5]
    • Organic material (nuts, seeds) most common in younger children
    • Inorganic objects (toy parts, pen caps) more common in older children
  • Risk factors include:
    • Absence of molar teeth (unable to properly grind food)
    • Immature swallowing coordination and laryngeal protective reflexes
    • Tendency to explore the environment orally
    • Eating while playing or running

Clinical Features

Ingested foreign body

  • Often asymptomatic if object has passed beyond the esophagus
  • Dysphagia
  • Drooling
  • Odynophagia
  • Vomiting or refusal to eat
  • Chest or abdominal pain
  • Globus sensation
  • If esophageal impaction: risk of airway obstruction, pooling of secretions

Aspirated foreign body

  • Classic triad: acute choking, cough, and wheezing[6]
  • Stridor (if laryngeal or tracheal)
  • Unilateral decreased breath sounds
  • Recurrent or persistent pneumonia (delayed presentation)
  • Asymptomatic period may follow initial choking episode ("symptom-free interval")

Ear foreign body

Nasal foreign body

Differential Diagnosis

Evaluation

Workup

  • Radiographs
    • AP and lateral views of neck, chest, and abdomen for suspected ingestion or aspiration
    • Coins in the esophagus appear as a round disc on AP view (en face) and a line on lateral
    • Button battery ingestion appears as a "double contour" or "halo sign" on AP view — critical to distinguish from coin[7]
    • Normal radiographs do not exclude foreign body (radiolucent objects such as fish bones, plastic, wood are not visible)
    • Inspiratory/expiratory films or bilateral decubitus films may demonstrate air trapping in aspirated foreign body
  • CT — consider if plain films are negative but clinical suspicion remains high
  • Metal detector — can be used for rapid identification of metallic objects in the esophagus[8]
  • Barium swallow — generally NOT recommended (risk of aspiration, coats mucosa making endoscopy more difficult)

Diagnosis

  • Diagnosis is often based on history (witnessed event, acute choking)
  • High index of suspicion in young children with unexplained respiratory symptoms, dysphagia, or recurrent pneumonia
  • Up to 40% of cases may have no witnessed aspiration event
  • Bronchoscopy is both diagnostic and therapeutic for airway foreign bodies

Management

Immediate airway management

  • If complete airway obstruction:
    • Infant (<1 year): 5 back blows followed by 5 chest thrusts
    • Child (>1 year): abdominal thrusts (Heimlich maneuver)
    • If object is visible, remove with Magill forceps — do NOT perform blind finger sweep
    • If unable to ventilate: attempt intubation (may push object distally, converting to partial obstruction)
    • Last resort: Cricothyrotomy (needle or surgical) or tracheostomy
  • See Aspirated foreign body

Esophageal foreign body

  • Button battery ingestion in esophagus = EMERGENT removal within 2 hours[9]
    • Can cause liquefactive necrosis, perforation, and fistula formation within hours
    • Administer honey (10 mL every 10 min if age >12 months) or sucralfate as temporizing measure while awaiting endoscopy[10]
    • Contact Poison control (National Battery Ingestion Hotline: 1-800-498-8666)
  • Multiple magnets or magnet + metallic object = Emergent endoscopic removal
    • Can cause pressure necrosis, fistula, perforation, and bowel obstruction between loops[11]
    • Single magnet ingestion can typically be observed if asymptomatic
    • Confirm single magnet with lateral radiograph (multiple magnets may stack)
  • Sharp or pointed objects in esophagus = Urgent endoscopic removal
  • Coins or blunt objects in esophagus
    • Observe for up to 12-24 hours (may pass spontaneously in ~30% of cases)[12]
    • Foley catheter removal may be considered for smooth, blunt objects impacted <24 hours
    • Endoscopy if object does not pass or if symptomatic

Gastric and intestinal foreign body

  • Most blunt objects that reach the stomach will pass without intervention
  • Indications for endoscopic removal from the stomach:
    • Objects >2.5 cm in diameter or >6 cm in length
    • Sharp objects
    • Button battery ingestion remaining in stomach >48 hours (controversial; some experts advocate earlier removal)
    • Symptomatic patients
  • Expectant management with serial imaging for small, blunt, asymptomatic objects
    • Repeat imaging if object has not passed within 4 weeks

Ear and nasal foreign body

Airway foreign body

  • Rigid bronchoscopy is the gold standard for removal in children[13]
  • Flexible bronchoscopy may be used as an adjunct
  • Consider ENT and/or anesthesia consultation
  • Post-removal: consider dexamethasone, bronchodilators, and/or racemic epinephrine

Disposition

  • Admit/OR if:
    • Esophageal button battery ingestion (emergent OR)
    • Multiple magnet ingestion with concern for impaction
    • Sharp esophageal foreign body
    • Airway foreign body requiring bronchoscopy
    • Symptomatic patient with signs of perforation, obstruction, or respiratory compromise
  • Discharge if:
    • Asymptomatic with blunt object beyond the esophagus
    • Successful removal of foreign body with asymptomatic post-removal observation
    • Provide strict return precautions: abdominal pain, vomiting, bloody stools, fever
    • Caregiver education on prevention (keep small objects out of reach, age-appropriate foods)
  • Follow-up
    • Serial imaging for retained gastric/intestinal foreign bodies if not removed
    • Return for repeat radiograph if object not passed within 4 weeks
