Newly developed Barrett's esophagus after subtotal esophagectomy.

Background And Study Aims: More detailed information regarding the early mucosal events that lead to intestinal metaplasia would be very beneficial for understanding the pathogenesis of Barrett's esophagus (BE). Gastroesophageal reflux and duodenogastroesophageal reflux play a major role in the pathogenesis of Barrett's esophagus. The aim of this study was to investigate the prevalence of newly developed BE in patients who had previously undergone a subtotal esophagectomy - a clinical condition characterized by the absence of a lower esophageal sphincter and massive gastroesophageal reflux.
