Do Eosinophilic Esophagitis (EOE) patients with food stuck who require esophageal dilation with endoscopy receive general anesthesia or twilight anesthesia?

Anesthesia Options for EOE Patients Requiring Esophageal Dilation for Food Impaction

Twilight anesthesia (conscious sedation) is the preferred anesthesia method for EOE patients with food bolus impaction requiring esophageal dilation, as it provides adequate sedation while maintaining airway reflexes and reducing risks of esophageal trauma.

Anesthesia Considerations for EOE Patients

Preferred Anesthesia Approach

• Monitored anesthesia care (MAC) with conscious sedation (twilight anesthesia) is the standard approach for endoscopic procedures in EOE patients 1
• This approach allows for:
  • Patient comfort during the procedure
  • Preservation of protective airway reflexes
  • Reduced risk of esophageal trauma compared to general anesthesia with intubation
  • Easier assessment of patient response during dilation

Risk Considerations

• EOE patients have increased risk of esophageal injury during intubation due to:
  • Possible esophageal strictures or narrowing
  • Fragile esophageal mucosa prone to tearing
  • History of food impaction indicating compromised esophageal lumen 2
• General anesthesia with intubation may increase risk of esophageal trauma in these already compromised patients 3

Procedural Protocol for Food Bolus Obstruction in EOE

Urgent Management

• Food bolus obstruction requires urgent referral to gastroenterology for endoscopic intervention 2
• Procedure should be performed on the next available endoscopy list or as an immediate emergency depending on clinical presentation 2
• Conservative treatments such as fizzy drinks or medications are not supported by evidence 2

Dilation Technique

• Wire-guided bougie dilation under conscious sedation has been shown to be safe in EOE patients 1
• Balloon dilation is also commonly used, with no significant difference in perforation risk between bougie and balloon techniques 4
• The endoscopist should:
  • Choose initial dilator size that approximates esophageal lumen diameter
  • Perform serial dilation in 1-3 mm increments
  • Aim for a final diameter of 15-18 mm 2
  • Reassess the esophagus after each dilation to check for mucosal tears 1

Safety Profile

• Perforation rates are very low (less than 1%) with modern techniques 5, 4
• Most common side effect is post-procedural chest pain (3.64%) 4
• Small mucosal tears are expected and considered a marker of successful dilation rather than a complication 5

Special Considerations

Anesthesia Support

• Anesthesiologist should be informed about the EOE diagnosis 3
• Airway management support should be available if needed during the procedure 2
• Gentle technique during any instrumentation is essential to avoid esophageal trauma 3

Post-Procedure Management

• Patients should be monitored for chest pain, which may require analgesia 2
• Anti-inflammatory treatment for EOE (topical steroids or dietary elimination) should be continued or initiated after dilation to prevent recurrence 2

Follow-up Recommendations

• Symptom response after dilation usually lasts up to 1 year 2
• Maintenance treatment with either topical steroid or dietary elimination should continue after dilation 2
• Repeat endoscopy is recommended at 6-12 weeks to assess treatment response 2

Twilight anesthesia provides the optimal balance between patient comfort and safety for EOE patients requiring esophageal dilation for food impaction, while minimizing the risk of complications associated with general anesthesia.
