Management of Esophageal Food Impaction

Initial Assessment

The World Journal of Emergency Surgery recommends that complete blood count, C-reactive protein, blood gas analysis, and lactate should be obtained as part of the initial evaluation 4
Plain radiographs of the neck, chest, and abdomen can help assess for radiopaque objects, but have limited utility for food impaction with false-negative rates up to 85% 5, 6
A CT scan should be performed if perforation or other complications are suspected, with sensitivity of 90-100% compared to only 32% for plain X-rays 4, 5
Contrast swallow studies are NOT recommended as they may increase aspiration risk and can impair subsequent endoscopic visualization 3, 5

The World Journal of Emergency Surgery recommends that for complete esophageal obstruction from food bolus, emergent flexible endoscopy (within 2-6 hours) is recommended due to risk of aspiration and perforation 1, 2, 3
For food bolus without complete obstruction, urgent flexible endoscopy (within 24 hours) is recommended 1, 2
During endoscopy, the recommended approach is to first attempt gentle pushing of the bolus into the stomach using air insufflation and instrumental pushing (90% success rate) 2, 3
If pushing fails, retrieval techniques using baskets, snares, or grasping forceps should be employed 2, 3

Diagnostic biopsies should be taken during the index endoscopy, with at least 6 biopsies from different anatomical sites in the esophagus 7
An underlying esophageal disorder is found in up to 25% of patients with food impaction 2, 3
The most common underlying conditions include eosinophilic esophagitis (found in up to 46% of patients with food bolus obstruction) 7
Other common underlying conditions include esophageal stricture, hiatus hernia, esophageal web or Schatzki ring, achalasia, and tumors 2, 3

Pharmacologic interventions have limited evidence and should not delay endoscopic management 1, 2, 3
There is no clear evidence that conservative treatments such as fizzy drinks, baclofen, salbutamol or benzodiazepines are helpful 7

If adequate biopsies were not obtained during the initial endoscopy, arrange for elective repeat endoscopy 7
For patients diagnosed with eosinophilic esophagitis, withhold PPI for at least 3 weeks before repeat endoscopy if symptoms persist 7
Outpatient review should be arranged to confirm the cause of food impaction, educate the patient, and institute appropriate therapy for any underlying condition 7

Failure to obtain diagnostic biopsies during the index endoscopy can lead to missed diagnoses, particularly eosinophilic esophagitis 7
Rigid endoscopy should be considered as a second-line approach if flexible endoscopy fails, particularly for food bolus in the upper esophagus 2, 3
Patients with food impaction may be lost to follow-up if not properly scheduled for outpatient review before discharge 7
