Reactive gastropathy, is characterized histologically by: [2] - Foveolar hyperplasia (black arrow), as a tortuosity in the "neck" region of the gastric glands. - Scant or minimal inflammatory cells (white arrow), i.e. lack of large numbers of neutrophils and plasma cells.. - Smooth muscle hyperplasia in the lamina propria (in black oval).
The area between the stratified and the intestinalized epithelium displays reactive changes, but there is no secondary dysplasia in this case. H&E stain. Barrett's esophagus occurs due to chronic inflammation. The principal cause of chronic inflammation is gastroesophageal reflux disease, GERD (UK: GORD). In this disease, acidic stomach, bile ...
Diagram of the alkaline mucous layer in the stomach with mucosal defense mechanisms. The gastric mucosa is the mucous membrane layer of the stomach, which contains the gastric pits, to which the gastric glands empty. In humans, it is about one mm thick, and its surface is smooth, soft, and velvety.
Reactive stains undergo an observable change due to a chemical process related to the function of the gastrointestinal tract. Congo red is used as a test for achlorhydria in the stomach, to test adequacy of vagotomy ( post adequate vagotomy, gastric acid secretion is abolished) and to detect presence of ectopic gastric tissue, as it changes ...
The gastric mucosa is covered in surface mucous cells that produce the mucus necessary to protect the stomach's epithelial lining from gastric acid secreted by parietal cells in the glands, and from pepsin, a secreted digestive enzyme. Surface mucous cells follow the indentations and partly line the gastric pits.
For example, heartburn is a symptom in lymphocytic esophagitis, and proton pump inhibitors, which reduce acidity in the stomach, are consequently used for treatment. With respect to treatment of inflammation, steroids that are topical and coat the lining of the esophagus, such as budesonide have been used to treat the condition, in one German ...

The large folds of the stomach, as seen in Ménétrier disease, are easily detected by x-ray imaging following a barium meal or by endoscopic methods. Endoscopy with deep mucosal biopsy (and cytology) is required to establish the diagnosis and exclude other entities that may present similarly.
