RésuméSept cas de foyers gastriques en muqueuse duodénale bulbaire sont rapportés, dont quatre cas d’hétérotopie gastrique (Fundique). [...] Key Method L’aspect endoscopique est celui de lésions polypoides confluentes dans les quatre cas d’hétérotopie, et de lésions nodulaires ou pseudo-villeuses focalisées dans les trois cas de formation glandulaire incomplète (antrale). La coloration par le Bleu de Méthylène permet une meilleure définition des lésions et montre leur caractère non absorbant. Le Rouge Congo…Expand

Méthodes de colorations vitales des muqueuses duodénales et intestinales
The use of megapixel videoendoscope with magnifying optical system associated to chromoscopy is powerful for the diagnosis and the follow-up of total or subtotal villous atrophis in celiac disease or its variants and in other malabsorption syndrome diseases (tropical sprue), etc. Expand

L'usage des colorants de muqueuse en endoscopie digestive haute: Intérêt, applications pratiques, perspectives
Application of dyes during oesophago-gastro-duodenoscopy either realises a vital staining if absorbed by the mucosa, or gives contrast changes to the normal mucosal, redness. Expand
Endoscopie du bulbe duodénal: apport de la coloration vitale au bleu de méthylène
The staining method using methylen blue in the duodenal bulb allows to visualize the patterns of villous relief, the stainer being absorbed by enterocytes, and to evaluate the healing stage of ulcerations. Expand
Heterotopic gastric (fundic) mucosa in the duodenum.
Biopsies obtained from the polyps revealed them to be composed of fundal mucosa, thus representing a particular form of heterotopia, other then the steroid-induced type, and that of patients undergoing regular dialysis for uraemia. Expand
Heterotopic gastric mucosa in the duodenum - reaction to Congo red under fiberscopic observation.
A 64-year-old woman had gastric heterotopic of the duodenal bulb without any specific complaints, and it was proved by an endoscopic Congo red test that the excrescence had a function of acid output. Expand
Heterotopic gastric mucosa in the duodenum.
Thirteen patients are described who, on routine endoscopy of the upper gastrointestinal (GI) tract, were found to show a characteristic appearance in the proximal duodenum, consisting of multiple small mucosal nodules, predominantly in the anterior wall, which are probably of little or no clinical significance. Expand
Heterotopic gastric tissue in the duodenum
Eight patients with intraduodenal gastric heterotopia are described and it is likely that more widespread use of upper-gastrointestinal endoscopy and biopsy under direct vision will lead to an increase in the reported incidence of a condition previously thought to be rare. Expand
Elevated lesions in the duodenal bulb caused by heterotopic gastric mucosa.
Heterotopic gastric mucosa in the duodenal bulb is sometimes seen as elevated lesions, and glucagon-induced hypotonia of the duodermal bulb facilitates the diagnosis. Expand
Gastric gland metaplasia in the small and large intestine.
Surgical specimens with various ulcerative intestinal disorders were microscopically investigated for evidence of gastric gland metaplasia, and among the 31 patients with pyloric gland metaPLasia, five showed true gastric metapl Asia, consisting of parietal cells, chief cells, and mucous neck cells.

Gastric and duodenal mucosa in 'healthy' individuals. An endoscopic and histopathological study of 50 volunteers.
The results of histological and immunohistochemical examination of gastric and duodenal biopsy specimens from 50 volunteers without a clinical history of gastrointestinal disease are reported, finding considerable variation in the appearance of the surface epithelium of the duodenum within as well as among individual subjects.

Hyperplasiogenic polyp in the duodenum.
Report on a 42-year-old patient with extensive heterotopia of gastric mucosa within the first portion of the duodenum which formed the matrix of a hyperplasiogenic polyp.
