Questions fréquentes

What is the stomach lamina propria?
The stomach lamina propria is the layer of loose connective tissue that lies immediately beneath the epithelial lining of the stomach. It forms the core of the gastric mucosa and contains gastric glands, blood vessels, lymphatics, nerve fibers, and various immune cells.
Where is the stomach lamina propria located?
The stomach lamina propria is located within the stomach wall, between the surface epithelium and the muscularis mucosae. It fills the spaces between gastric glands that extend from the surface down through the mucosal layer, and it spans all regions of the stomach including the fundus, body, and antrum.
What is the function of the stomach lamina propria?
The stomach lamina propria supports the gastric glands that produce acid, pepsinogen, mucus, and intrinsic factor. It houses immune cells that patrol the gastric mucosa and contains blood vessels that supply nutrients and oxygen to the epithelium. It also plays a role in the mucosal immune response to pathogens.
What conditions may affect the stomach lamina propria?
The stomach lamina propria may be associated with Helicobacter pylori infection, which causes chronic gastritis with inflammatory cell infiltration. Autoimmune gastritis, peptic ulcer disease, and gastric adenocarcinoma may also involve changes within the lamina propria.
How is the stomach lamina propria examined?
The stomach lamina propria is examined through gastric biopsies obtained during upper endoscopy (gastroscopy). Histological assessment of biopsy tissue evaluates glandular architecture, inflammatory infiltrates, and the presence of organisms such as H. pylori using special stains.
