Heterotopic gastric mucosa of the proximal oesophagus (inlet patch): endoscopic prevalence, histological and clinical characteristics in paediatric patients

摘要

Heterotopic gastric mucosa is found in the proximal oesophagus, just below the upper oesophageal sphincter, and is encountered when the oesophagus is examined carefully during endoscopy. Aims In this study on paediatric patients, we aimed to determine the endoscopic prevalence of heterotopic gastric mucosa of the proximal oesophagus (HGMPO), to identify its macroscopic and histological characteristics and to evaluate its clinical features. A total of 1399 patients were examined. Ages, sex, clinical and endoscopic findings of all patients were recorded. Patients with HGMPO were classified in accordance with a clinicopathological classification and information on the treatment and evolution was also recorded.
