Esophageal Foreign Body

1. History

• What was swallowed? Identify the object type (food bolus, bone, coin, button battery, magnet, sharp object, toy). In adults, fish and chicken bones are the most common; in children, coins are most common. [1-2]
• When did it happen? Time of ingestion is critical — drives urgency of endoscopy. Impaction time >24 hours is associated with increased major complications. [3]
• Can the patient swallow liquids/saliva? Inability to handle secretions = complete obstruction → emergent endoscopy. [4]
• Choking, gagging, or vomiting at onset? Classic presenting symptoms. [1]
• Dysphagia vs. odynophagia? Localize the sensation — patients often point to the suprasternal notch or chest.
• Was the ingestion witnessed? In children, most ingestions are unwitnessed. [2]
• Prior episodes of food impaction or dysphagia? Suggests underlying esophageal pathology (eosinophilic esophagitis, stricture, Schatzki ring) — present in up to 80% of adults with food impaction. [5]
• Intentional vs. accidental? Psychiatric patients and prisoners may intentionally ingest dangerous objects.

2. Alarm Features

• Inability to swallow secretions/drooling → complete obstruction, aspiration risk [1][4]
• Stridor, respiratory distress, or cyanosis → airway compromise or tracheal foreign body
• Chest pain, fever, tachycardia → suspect perforation, mediastinitis
• Subcutaneous emphysema (crepitus) in the neck → esophageal perforation with pneumomediastinum [6]
• Hematemesis → vascular erosion, especially post–button battery ingestion
• Button battery in the esophagus → tissue necrosis begins within 15 minutes; aortoesophageal fistula can be fatal [2]
• Multiple magnets ingested → pressure necrosis, fistula, perforation [2]
• Sharp objects in the esophagus → up to 35% risk of full-thickness perforation [4]

3. Medications

Pharmacologic agents for food bolus impaction (limited efficacy):

• Glucagon 1 mg IV: Traditionally used to relax the lower esophageal sphincter. A meta-analysis of 1,185 patients found no difference vs. placebo (30.2% vs. 33.0%, OR 0.90, p=0.42) with higher adverse events. A 2024 multicenter RCT confirmed glucagon is no more effective than placebo. Particularly ineffective in patients with eosinophilic esophagitis. Should not delay endoscopy. [7-9]
• Effervescent agents (e.g., carbonated beverages): One retrospective study showed 55.6% success as monotherapy vs. 17.7% for glucagon. Mechanism: gas distension propels bolus distally. Contraindicated with complete obstruction (aspiration risk). [10]
• Calcium channel blockers, benzodiazepines, nitrates: Evaluated but efficacy is poor; not routinely recommended. [1]
• Papain/proteolytic enzymes: Contraindicated — associated with esophageal perforation and aspiration pneumonitis. [6]

Button battery–specific interim treatment

• Honey (children >12 months): 10 mL every 10 minutes for up to 6 doses en route to ED, within 12 hours of ingestion [2]
• Sucralfate: 1 g every 10 minutes for 3 doses in-hospital while awaiting EGD [2]

4. Diet

• NPO immediately upon presentation — anticipate endoscopy
• Avoid oral contrast studies (aspiration risk, interferes with subsequent endoscopy) [4]
• Post-removal: advance diet gradually from liquids to soft foods; avoid tough meats initially
• Long-term: patients with recurrent food impaction from eosinophilic esophagitis may benefit from elimination diets (1-, 2-, 4-, or 6-food elimination) [11]
• Counsel on thorough chewing, cutting food into small pieces, and avoiding eating quickly — behavioral factors contribute to food impaction [12]

5. Review of Systems

• ENT: Sore throat, globus sensation, voice change, neck swelling
• Respiratory: Cough, stridor, wheezing, dyspnea (aspiration or airway FB)
• GI: Dysphagia (acute vs. chronic), odynophagia, chest pain, heartburn, abdominal pain, hematemesis, melena
• Constitutional: Fever (suggests perforation/infection)
• Psychiatric: Intentional ingestion, self-harm history

6. Collateral History and Family History

• Collateral: Witnesses to the ingestion event (especially in children and nonverbal patients); type and size of object if known; packaging/product information for batteries or magnets
• Family history: Atopic conditions (asthma, eczema, allergic rhinitis) — associated with eosinophilic esophagitis [11]
• Social context: Psychiatric illness, incarceration (body packing, intentional ingestion), developmental delay, elderly with cognitive impairment

7. Risk Factors

• Children 6 months–5 years: Peak incidence; 75% of >116,000 annual ingestions in the US [12]
• Edentulous adults: Greatest risk in adult population [1]
• Underlying esophageal pathology: Stricture, Schatzki ring, eosinophilic esophagitis, esophageal web, achalasia, tumors — found in up to 25% of patients [4]
• Eosinophilic esophagitis: ~50% of adults presenting emergently with food impaction have EoE [13]
• Prior esophageal surgery: Atresia repair, Nissen fundoplication [12]
• Psychiatric illness/intellectual disability: Intentional or repeated ingestion
• Older adults: More likely to experience prolonged impaction [14]
• Alcohol use: Impairs judgment, increases accidental ingestion of bones

8. Differential Diagnosis

• Esophageal food bolus impaction (most common in adults)
• True foreign body (coin, battery, bone, denture)
• Globus pharyngeus — foreign body sensation without actual FB
• Esophageal perforation (Boerhaave syndrome) — if post-retching with chest pain
• Esophageal motility disorder (achalasia) — mimics obstruction symptoms [15]
• Esophageal stricture or malignancy — progressive dysphagia without acute ingestion event
• Retropharyngeal abscess — neck pain, dysphagia, fever
• Airway foreign body — if cough, stridor, or unilateral wheeze predominate
• Zenker's diverticulum — regurgitation of undigested food, halitosis [15]

9. Past Medical History

• Prior food impactions or esophageal foreign bodies
• Known eosinophilic esophagitis, GERD, esophageal stricture, Schatzki ring
• Prior esophageal dilation or surgery
• Esophageal atresia repair (pediatric)
• Psychiatric history (intentional ingestion)
• Dentures or dental prostheses
• Atopic conditions (asthma, eczema, food allergies)

10. Physical Exam

• Airway assessment first — stridor, drooling, respiratory distress [1]
• Vitals: Tachycardia, fever (perforation), hypoxia (aspiration)
• Oropharynx: Inspect for visible foreign body, pooling of secretions
• Neck: Tenderness, subcutaneous emphysema/crepitus (perforation with pneumomediastinum) [6]
• Chest: Auscultate for asymmetric breath sounds (airway FB), crackles (aspiration)
• Abdomen: Tenderness, peritoneal signs (if FB has migrated distally and perforated)
• Skin: Drooling, inability to swallow — hallmark of complete obstruction

11. Lab Studies

• CBC: Leukocytosis may suggest perforation or infection
• CRP: Elevated in perforation/mediastinitis [4]
• Blood gas with lactate: If sepsis or perforation suspected [4]
• BMP: Baseline if procedural sedation or general anesthesia anticipated
• Type and screen: If concern for vascular erosion (especially post–button battery)
• Labs are generally not required for uncomplicated food bolus impaction in a stable patient

12. Imaging

First-line

• Plain radiographs (AP and lateral of neck, chest, and abdomen): Useful for radiopaque objects (coins, batteries, metallic FBs). Sensitivity is 100% for coins but only 26% for fish bones and 33% for chicken bones. False-negative rate up to 47% overall, and up to 85% for food bolus, thin metal, wood, plastic, and bone fragments. [2][4]
• Lateral view is critical: Differentiates esophageal from tracheal FB (esophageal coins appear en face on AP; tracheal coins appear en face on lateral). Also distinguishes button batteries (double-rim/halo sign on AP, step-off on lateral) from coins. [12]

When radiographs are negative or complications suspected

• CT scan[4][12]

Not recommended

• Contrast swallow/barium study[4][12]

Imaging may be unnecessary if non-bony food bolus is suspected with no concern for perforation — proceed directly to endoscopy. [1]

13. Special Tests

• Flexible fiberoptic laryngoscopy: Inadequate for ruling out esophageal FB (sensitivity only 25%) but useful for hypopharyngeal objects [16]
• Esophageal biopsies during EGD: Should be obtained at the time of food impaction removal to evaluate for eosinophilic esophagitis (≥15 eos/hpf) — biopsy away from the impaction site. Failure to biopsy necessitates a repeat endoscopy. [17]
• Magill forceps: Useful for removal of FB in the oropharynx/upper esophagus under direct laryngoscopy [6]

14. ECG

• Not routinely indicated for uncomplicated esophageal FB
• Obtain if:
  • Chest pain is present (rule out cardiac etiology)
  • Pre-procedural assessment for sedation/general anesthesia
  • Button battery ingestion with concern for mediastinal/vascular involvement
  • Elderly patient with comorbidities

15. Assessment

Severity stratification by urgency of endoscopy (per WSES and ESGE guidelines): [3-4]

Key clinical pearls:

• 80–90% of ingested FBs pass spontaneously, but all esophageal FBs require removal [4][18]
• Most common impaction site: proximal esophagus at the cricopharyngeus [2]
• Endoscopic removal within 6 hours reduces complication rates [3]
• Approximately 50% of adults with food impaction have underlying eosinophilic esophagitis [13]

16. Treatment Plan

Initial stabilization

• Airway assessment and management — suction secretions, position upright
• NPO status
• IV access

Endoscopic management (first-line definitive treatment)

• Food bolus: Push technique (gentle advancement into stomach) — up to 90% success rate with low complication rate. If unsuccessful, piecemeal retrieval with forceps, snare, or net. [4]
• Sharp objects: Retrieve with forceps/snare; use overtube or distal cap to protect mucosa during withdrawal [6]
• Button batteries in esophagus: Emergent removal, preferably within 2 hours. Post-removal: irrigate with 50–150 mL of 0.25% acetic acid to neutralize ongoing alkaline injury. Monitor for delayed complications (aortoenteric fistula) for weeks after removal. [2][19]
• Coins in esophagus: If present >12–24 hours or in proximal esophagus of young child → EGD. Distal esophageal coins in older children may be observed for 12–24 hours for spontaneous passage. [2]
• Magnets: Multiple magnets or magnet + metallic object → emergent EGD or surgical removal [2]
• General anesthesia with endotracheal intubation is recommended, especially in children, to protect the airway [6]

Pharmacologic adjuncts (for food bolus only, while awaiting endoscopy):

• Effervescent agents (e.g., carbonated beverage) may be trialed if partial obstruction and patient can swallow safely [10]
• Glucagon 1 mg IV: Evidence does not support efficacy over placebo; should not delay endoscopy [7-8]

Surgical indications

• Perforation, mediastinitis, peritonitis [4]
• FB irretrievable by endoscopy or close to vital structures [4]
• Object immobile or beyond reach of EGD for >1 week [2]

17. Disposition

Admission criteria

• Perforation or suspected perforation (pneumomediastinum, pneumoperitoneum)
• Post–button battery removal — monitoring for delayed vascular complications [2]
• Failed endoscopic removal requiring surgical intervention
• Significant mucosal injury on endoscopy
• Hemodynamic instability or airway compromise

Observation

• Post-EGD monitoring for 4–6 hours if uncomplicated removal
• Patients with partial obstruction being trialed on conservative management

Discharge criteria

• Successful uncomplicated removal with ability to tolerate oral intake
• No signs of perforation or significant mucosal injury
• Reliable follow-up arranged

Specialist consultation triggers

• GI/endoscopy: All persistent esophageal FBs [4]
• Surgery (general or cardiothoracic): Perforation, pneumomediastinum, pneumoperitoneum, irretrievable FB [2]
• ENT/rigid endoscopy: FB in upper esophagus or hypopharynx, concomitant airway symptoms [4]
• Pediatric GI: All button battery and magnet ingestions in children [2]
• Psychiatry: Intentional/repeated ingestion

18. Follow Up / Return Precautions

Follow-up timing

• GI follow-up within 1–2 weeks post-removal for biopsy results (EoE workup) and to discuss underlying pathology
• Post–button battery removal: Repeated imaging and surgical consultation to monitor for delayed complications (fistula, vascular injury) — can occur days to weeks after removal [2]
• Recurrent food impaction: Outpatient EGD with biopsy for EoE evaluation; consider esophageal dilation if stricture identified [11][20]

Return precautions — instruct patients to return immediately for:

• Fever, worsening chest or abdominal pain
• Hematemesis or bloody stools
• Inability to swallow liquids or saliva
• Neck swelling or crepitus
• Shortness of breath

Patient counseling

• Cut food into small pieces, chew thoroughly, eat slowly
• Avoid tough meats and bread (common impaction foods)
• If recurrent impaction, emphasize importance of EoE workup and adherence to treatment
• Expected recovery: Most patients recover fully after uncomplicated removal; mild sore throat and odynophagia for 1–3 days is normal
