BACKGROUND AND AIM: It is clinically important to diagnose drug-induced gastric lesions correctly. Recently, the use of proton pump inhibitors (PPI) has increased worldwide. The histological features induced by PPI have been reported; however, few reports have described endoscopic findings induced by PPI. Therefore, we aimed to clarify the characteristic endoscopic features in PPI users and associated pathogenic factors.
METHODS: We prospectively registered 1007 consecutive participants (70 PPI users and 937 nonusers) who underwent endoscopic examination for cancer screening in three hospitals/clinics. Clinical data and endoscopic findings were recorded in the registration forms. We compared the endoscopic features between the two groups and evaluated contributing factors via univariate and multivariate analyses.
RESULTS: Multiple white elevated lesions (MWEL) and cobblestone-like mucosa (CLM) were more commonly observed in PPI users compared with nonusers (p < .01). Foveolar hyperplastic polyps were also frequently observed in PPI users but were not statistically significantly different (p = .06). MWEL and CLM were more frequently observed in older patients than in younger patients. MWEL was more frequently observed in female patients than in male patients; however, CLM was predominantly observed in male patients.
CONCLUSION: MWEL and CLM are characteristic endoscopic features in PPI users. A gender-associated difference was noted in terms of the frequency of these lesions.
