Abstract/Text
BACKGROUND AND AIM: Esophageal eosinophilia (EE) is the most important finding for the diagnosis of eosinophilic esophagitis. We conducted the present retrospective study to clarify the most suitable site of the esophagus to examine for EE detection. METHODS: We enrolled 4999 subjects who underwent upper gastrointestinal endoscopy screening examinations as part of a detailed health check-up. When endoscopic esophageal abnormalities characteristic of eosinophilic esophagitis were observed, two or three biopsy specimens were obtained from the middle or lower esophagus, and endoscopic findings of fixed rings, exudates, furrows, edema, stricture, and crepe paper esophagus in biopsied sites were analyzed. RESULTS: Thirty-five subjects underwent histological examination for EE, of whom 20 showed positive findings in biopsied specimens. Higher grade endoscopic findings of exudates, furrows, and edema were observed in cases with EE in comparison to the 15 without EE, whereas statistically significant higher grade endoscopic findings of exudates, furrows, and edema were also observed in biopsied sites with EE in comparison to those without EE. In addition, a positive finding of EE in biopsied specimens from the lower esophagus was significantly more frequently noted as compared to those from the middle esophagus. Multiple logistic regression analysis showed that a lower esophagus biopsy site and severe exudates were significant factors related to a positive EE finding in biopsied specimens. CONCLUSION: The most suitable conditions for detection of EE are a lower esophagus biopsy site and the presence of exudates in cases suspicious of eosinophilic esophagitis shown by endoscopy.
