Retrospective analysis of esophageal food impaction: differences in etiology by age and gender.

Eosinophilic Esophagitis (EE) is an emerging cause of esophageal food impaction (EFI) not accounted for in previous studies. We sought to determine the causes of EFI in a recent cohort with recognition of EE. A retrospective chart review of all patients with EFI during the past 5 years was performed. Etiology was determined by endoscopy report, pathology results, and follow-up studies. A total of 85 EFIs occurred, in 79 patients (55 men, 30 women, age 18-100). The most common etiologies of EFI were Schatzki's ring (n = 18), peptic stricture (n = 18), EE (n = 9), esophagitis (n = 9), and no underlying diagnosis (n = 20). EE was significantly more frequent in men (P < .025) and those <50 years old (P < .025). There was a significant difference in the age at which men (median age = 44) and women (median age = 71) present with EFI (P < .001). The etiology of EFI differs significantly by age and gender. This information may be useful in evaluation and management of EFI.
