DIAGNOSIS
SIGNS AND SYMPTOMS
General
  • Dysphagia: Difficulty swallowing
  • Odynophagia: Pain with swallowing
  • Chest pain: Angina like, often pleuritic, severe, and unrelenting
  • Hoarseness
  • Dyspnea
  • Tears or perforations:
    • Bleeding
    • Hematemesis
  • Ingestions/foreign bodies:
    • Drooling or excessive salivation
    • Choking, gagging, vomiting, stridor, or wheezing
    • Inability of food or liquid to pass
  • Caustic ingestions:
    • Oral pain
    • Abdominal pain
    • Vomiting
    • Drooling
History
  • History of ingestions (type, time, amount)
  • History of protracted vomiting
  • History of inability to swallow after eating, foreign body sensation in throat
  • History of penetrating trauma
  • History of cancer therapy
Physical-Exam
  • Tears or perforations:
    • SubQ air at base of neck
    • Hamman crunch:
      • Systolic crunching sound secondary to air in mediastinum
    • Shock
    • Septicemia
    • Peritonitis
  • Penetrating trauma:
    • Associated neck, chest, or abdominal injury with trauma:
      • Most commonly trachea
      • Associated with penetrating/blunt trauma
  • Caustic ingestions:
    • Airway edema leading to stridor
    • Oral burns
ESSENTIAL WORKUP

High level of suspicion and early diagnosis are key:

  • Mortality <5% for perforation if repaired within 24 hr; 75% if delayed
  • Early endoscopy for caustic ingestions
  • Chest/lateral neck radiograph
DIAGNOSIS TESTS & NTERPRETATION
Lab
  • CBC in cases of GI bleeding
  • TXC for any extensive bleeding/OR candidate
  • Coagulation studies
  • Electrolytes for protracted vomiting or prolonged foreign body retention
  • Arterial blood gas (ABG) for acid ingestions
Imaging
  • CXR for foreign body or perforation:
    • Pneumomediastinum
    • Widened mediastinum
    • Pneumothorax
    • Pleural effusion
  • Lateral cervical spine films for foreign body or perforation:
    • Retropharyngeal air or fluid
    • Cervical emphysema
  • Fiberoptic nasopharyngoscopy for foreign body removal
  • Esophagram for foreign bodies or suspected perforation:
    • 10–25% false-negative rate
    • Current recommendations for water-soluble contrast (Gastrografin) 1st if perforation likely
    • Barium may limit visibility for later endoscopy:
      • More irritating if extravasates into mediastinum
    • Water-soluble contrast provides better visibility:
      • Less reaction if extravasates into mediastinum
      • May cause chemical pneumonitis if aspirated
    • Nonionic contrast may be safest but more expensive
  • Endoscopy for suspected perforation, caustic ingestions, and esophageal foreign body removal
    • Severity of injury in caustic ingestions
      • 1st degree: Superficial mucosal damage, focal or diffuse, erythema, edema, mucosa sloughs without scar
      • 2nd degree: Mucosal and submucosal damage, ulcers and vesicles, granulation tissue and scar formation, stricture possible
      • 3rd degree: Transmural with deep ulcers, black discoloration, and wall perforation
  • CT scanning with dilute oral contrast may be useful in diagnosis of perforations.
DIFFERENTIAL DIAGNOSIS
  • Pulmonary:
    • Tracheal injury
    • Pneumothorax
  • Cardiovascular:
    • Myocardial infarction
    • Aortic dissection
    • Spontaneous pneumomediastinum
  • Other esophageal emergencies:
    • Peptic stricture
    • Esophageal neoplasm
    • Schatzki ring
    • Diverticula
    • Achalasia
    • Diffuse esophageal spasm
    • Nutcracker esophagus
    • Gastroesophageal reflux
    • Esophagitis
      • esophagitis esp. teracycline
TREATMENT
PRE HOSPITAL
ALERT
  • Chest pain should be presumed cardiac.
  • Airway protection, frequent suctioning
  • Intravenous crystalloid if patient is hypotensive, vomiting, or if hematemesis is present
  • Pain management
  • Avoid neutralizing agents in caustic ingestions as that may worsen injury.
  • Avoid copious amounts of oral fluids in caustic ingestions to prevent emesis.
INITIAL STABILIZATION/THERAPY
  • Manage airway and resuscitate as needed
  • Intravenous access, monitoring
  • Early intubation for penetrating neck and chest wounds
  • Frequent suctioning of copious secretions
  • Fluid replacement
ED TREATMENT/PROCEDURES
  • Foreign bodies/food impaction:
    • 80% pass, 20% need endoscopy, <1% need surgery
    • Glucagon may be tried: 1 mg IV and repeated in 20 min. Carbonated beverage in combo may be more effective
    • Nitroglycerin or nifedipine may be tried.
    • Diazepam may be of benefit in the upper (striated muscle) esophagus.
    • GI consultation and endoscopic extraction if not relieved
  • Caustic ingestions:
    • Emesis/lavage contraindicated
    • Immediate decontamination with milk
    • Avoid neutralizing agents as they may cause exothermic reaction.
    • GI consultation for early endoscopy to provide prognostic information
    • No role for corticosteroids and may be harmful
  • Tears/perforations:
    • Partial-thickness tears usually heal spontaneously.
    • GI consultation may be needed for diagnosis (endoscopy).
    • Perforation requires surgical consultation for thoracotomy and primary repair; some patients may be managed nonoperatively.
    • Broad-spectrum parenteral antibiotics for perforation
Pediatric Considerations
  • Certain swallowed foreign bodies require GI consultation and endoscopic removal:
    • Sharp objects: Fish bones, straight pins, razor blades, pencil
    • Caustic objects: Button batteries
  • Objects may pass on their own:
    • Coins, buttons, marbles
    • Open safety pins may pass spontaneously if blunt end forward.
  • Consult pediatric GI specialist.
MEDICATION
  • Foreign bodies/food impactions:
    • Glucagon: 1–2 mg (peds: 0.02–0.03 mg/kg) IV; may repeat once in 20 min
    • Nitroglycerin: 0.4 mg sublingually
    • Diazepam: 5–10 mg (peds: 1–2 mg) IV
  • Perforation:
    • Cefoxitin: 1–2 g (peds: 100–160 mg/kg/24 h) IV q6–8h
    • Gentamicin: 1–1.7 mg/kg (peds: 1.5–2.5 mg/kg/24 h) IV q8h
    • Steroids not indicated in caustic ingestions
FOLLOW-UP
DISPOSITION
Admission Criteria
  • Caustic ingestion
  • Sharp foreign bodies
  • Airway compromise
  • Penetrating neck or chest trauma
  • Evidence of sepsis, mediastinitis, or esophageal perforation
  • Significant bleeding
  • Inability to tolerate oral fluids
Discharge Criteria
  • Self-limited bleeding from partial-thickness tear
  • Foreign body or food impaction that has passed lower esophageal sphincter
PEARLS AND PITFALLS

Factors to predict outcomes in esophageal injuries:

  • Time to diagnosis and definitive therapy: 24 hr decreases mortality by half.
  • Location of injury: Cervical less than thoracic or abdominal
  • Mechanism of injury: Spontaneous perforation has highest mortality 30–40%; iatrogenic 15–20%, and direct trauma 5–10%.
