which ones underwent endoscopy, nor the demographic details of those with BE and those without this pathology. The authors in a retrospective analysis of 582 patients with grade I-III esophagitis (Savary-Monnier classification) diagnosed at endoscopy during a 27-year period, in the follow-up for 6.5 years, 45 (8%) developed BE [29]. But the study was reported only in abstract form and neither the diagnostic criteria, the demographic characteristics of the patients, nor the drug history were described.

In an interesting study investigating the progression of NERD in BE, Bajbouj et al. [30] described that two of a group of 34 patients (6%) with typical GERD symptoms and a normal endoscopy had developed BE after a 35-month follow-up. No data are given for the treatment. As in many other works, the length of the BE segment, as well as the demographic data for the patients, were not given. As stated above, from 1–13% of patients with erosive esophagitis develop BE each year.
