Heterotopia of gastric mucosa and long segmental Barrett’ oesophagus complicated by cicatricial stricture of the upper third of the oesophagus

Abstract

A 26-year-old patient with no symptoms of gastroesophageal reflux disease developed complaints of dysphagia. Endoscopic examination revealed a short grade 3 cicatricial stricture in the upper third of the oesophagus, and in the lower parts of the oesophagus mucosa was represented by a columnar epithelium for 16 cm. Histological examination verified the long segmental Barrett’ oesophagus. Above the stricture large areas of heterotopia of the gastric mucosa were determined among the regular oesophageal squamous epithelium. While taking proton pump inhibitors, the patient underwent a long course of endoscopic bougienage with intramural dexamethasone injections, which made it possible to stabilize the lumen in the stricture zone at a level of 12 mm. A precise examination of all parts of the oesophagus with the use of modern clarifying imaging techniques allows to correctly interpret the endoscopic picture and determine the further tactics of treatment and follow-up, taking into account the possible risks of neoplasia in the heterotoped area of the mucosa of the upper third of the oesophagus.
