Prevalence of Eosinophilic Esophagitis and Lymphocytic Esophagitis in Adults with Esophageal Food Bolus Impaction

Table 1

Aetiology of esophageal food impactions in all 238 patients and in 185 patients with obtained biopsy samples from the esophagus.

Schatzki ring without signs of EoE, LyE, or erosive esophagitis.
Posttraumatic or postsurgical.
Esophagus diverticula = 4, dyskinesia due to other diseases = 7, presbyesophagus = 7, and achalasia = 2.
GERD: gastroesophageal reflux disease, EoE: eosinophilic esophagitis, LyE: lymphocytic esophagitis, EoE/LyE: compound eosinophilic esophagitis and lymphocytic esophagitis (patients fulfilled criteria for both EoE and LyE), and PPI-REE: proton pump inhibitor-responsive esophageal eosinophilia.
