Aim: To investigate endoscopic findings in patients with Schatzki rings (SRs) with a focus on evidence for eosinophilic esophagitis (EoE).Methods: We consecutively approached all adult patients scheduled for elective outpatient upper endoscopy for a variety of indications at the German Diagnostic Clinic, Wiesbaden, Germany between July 2007 and July 2010. All patients with endoscopically diagnosed SRs, defined as thin, symmetrical, mucosal structures located at the esophagogastric junction, were prospectively registered.
