Heterotopic gastric mucosa in the cervical esophagus (inlet patch): Endoscopic prevalence, histological and clinical characteristics

Abstract

Background and Aim: Heterotopic gastric mucosal patch, which has a 0.1-10% frequency, is encountered when the cervical esophagus is examined carefully during endoscopy. In this study, we aimed to determine the prevalence of the patch in the cervical esophagus, to identify its macroscopic and histological characteristics and to evaluate demographic and clinical features.
