    Journal: Z Gesamte Inn Med; 1977 Aug 01; 32(15):371-4. PubMed ID: 919655.
    Abstract:
    On the basis of 8 observations in 3,140 duodenoscopies is referred to the endoscopic picture of heterotopies of the gastric mucous membrane. The heterotopic mucous membrane of the stomach was found in polypoid rice-grain-sized to pea-sized lesions of the duodenum. The histological examination four times resulted in a mucous membrane of the stomach of corpus type, three times of antrum type and once only in foveolar epithelium. As to other findings endoscopically were twice observed erosions of the gastric mucous membrane or of the mucous membrane of the bulb, respectively, once an antrum polypus, in no case ulcers. Once an achlorhydria was present. A hyperchlorhydria was to be proved in no case. The clinical significance of the heterotopia of the gastric mucous membrane in the duodenum as well as the cause of its existence are discussed.
