CASTANO LLANO, Rodrigo et al. Secreción ácida a partir de la heterotopia gástrica en esófago cervical demostrada por pHmetría de 24 horas. Rev Col Gastroenterol [online]. 2004, vol.19, n.3, pp.178-182. ISSN 0120-9957.

Heterotopic gastric mucosa may occur throughout the gastrointestinal tract, including the upper esophagus. The capability of this ectopic mucosa to secrete acid has been suggested in scanty reports. We report ten cases of heterotopic gastric mucosa in the upper esophagus, with secretion of acid, demonstrated by continuous ambulatory pH monitoring, and the narrow correlation of the presence of Helicobacter pylori in the gastric inlet patch and the gastric antrum.

Keywords : Gastric inlet patch; Ambulatory pH monitoring; Helicobacter pylori.
