 To examine the prevalence and endoscopic characteristics of DIE(dabigatran-induced esophagitis), we retrospectively reviewed endoscopic database and medical records of 110 patients who used dabigatran and underwent upper gastrointestinal endoscopy. Among the 110 patients, DIE was found in 21(19.1%)patients. Of the 21 patients, 20(95.2%)showed longitudinally sloughing epithelial casts in the mid- and/or lower esophagus, which may be characteristic endoscopic findings of DIE. Symptomatic patients tended to be more frequent in patients with DIE than patients without DIE. Other factors did not differ between the two groups. While discontinuation of dabigatran and administration of proton-pump inhibitor was useful for the treatment of DIE, instructing patients on the appropriate methods for taking dabigatran is important for preventing this disease.
