Incidence of heterotopic gastric mucosa in the upper oesophagus.

Abstract

In a prospective study of the frequency and clinical importance of heterotopic gastric mucosa in the upper oesophagus, 634 consecutive veteran patients (98% male), undergoing endoscopy for various gastrointestinal complaints, were evaluated. Sixty four patients (10%) had heterotopic gastric mucosal patches varying in size from 0*2-0*3 cm to 3x4-5 cm often immediately below the upper oesophageal sphincter. Biopsies of these patches showed fundic type gastric mucosa with chief and parietal cells. The 10% prevalence is more than twice the highest reported prevalence rate of endoscopically detected patches in the upper oesophagus. The characteristic location of these patches at the sphincter area, their uniformly fundic type gastric mucosa, and their poor correlation with clinical and endoscopic evidence of gastro-oesophageal reflux support the hypothesis that they are congenital in nature.

Use of Magnifying Endoscopy to Identify Early Esophageal Adenocarcinoma in Ectopic Gastric Mucosa of the Cervical Esophagus

“…C onsidering that the prevalence of ectopic gastric mucosa (EGM) of the cervical esophagus is by no means low endoscopically (10%-14.2% 1,2 ) and also experimentally, the malignant potential seems to be extremely low because cases of cervical esophageal adenocarcinoma arising in an EGM are extremely rare. In addition, carcinogenesis of EGM of the cervical esophagus has remained unclear.…”

Mucosa gástrica heterotópica en esófago cervical: presentación de un caso de compromiso circunferencial con estenosis franqueable A Case Report of Circumferential Presentation with Stricture

“…Esta entidad, descrita por Schmidt en 1805 (3), también es conocida como islas de parches gástricos en esófago, inlet patch o cervical inlet patch (4,5). No se tiene una comprensión cierta sobre su origen, fisiopatología y necesidad de tratamiento.…”

“…No se tiene una comprensión cierta sobre su origen, fisiopatología y necesidad de tratamiento. Su condición congénita ha sido aceptada pero nunca probada (1,5) y estudios recientes proponen un origen adquirido (6,7). La prevalencia reportada en estudios endoscópicos con luz blanca es variable, del 1% al 10% en adultos (8) y del 5,9% en niños (2,9).…”
