Chronic superficial gastritis and chronic atrophic gastritis difference
Chronic superficial gastritis and chronic atrophic gastritis is a chronic gastritis with the two very similar clinical manifestations and therefore distinguish between chronic superficial gastritis and chronic atrophic gastritis in the light of the relevant laboratory examinations, particularly the importance of endoscopy and biopsy of gastric mucosa . The key differences are as follows:
(1) gastric biopsy: chronic superficial gastritis of the basic lesion is epithelial cell degeneration, epithelial hyperplasia and the inherent pit membrane infiltration of inflammatory cells, but also can be seen even pit the surface of epithelial cells and intestinal epithelial metaplasia. The disease mainly involving the gastric mucosal inflammatory lesions shallow, and sometimes also involving the deep. Domestic pathology professional group discussions provided for by the degree of inflammatory cell infiltration depth, superficial gastritis can be divided into light, medium and heavy 3. Profound part of the gastric mucosa from the surface into three equal portions, cell infiltration involving only the superficial 1 / 3 were mild, involving the 2 / 3 less than those for the moderate, more than 2 / 3 of those was severe. No matter how the severity of inflammatory lesions, superficial gastritis of the gastric glands (cardiac glands, gastric glands, pyloric glands) are always normal, there is no damage or reduction in the number. Superficial gastritis further development of the gland because of its inherent damage reduction in inflammation can be converted into atrophic gastritis.
Chronic atrophic gastritis, gastric mucosa is based on the inherent gland atrophy (decrease in the number, functional reduction) as its prominent lesions, often accompanied by intestinal metaplasia and inflammatory response. Gland by impact inherent in the extent of chronic atrophic gastritis will be divided into mild, moderate and severe three. Inherent in the stomach glands (glands in the pyloric antrum of the stomach at the bottom of gastric glands, cardiac glands in the cardia as) reducing the 1 / 3 of those for the mild, a decrease of 1 / 3 ~ 2 / 3 were moderate, a decrease of 2 / 3 or more severe.
(2) endoscopy: chronic superficial gastritis in the performance of endoscopic mainly: ① gastric mucosal hyperemia, edema, congestion zones and edema zones can intersect to form a red and white, and red with congestion-based; ② gastric mucosal surface, attached to thick patches of white or yellow mucus; ③ gastric bleeding points; ④ mucosa and sometimes can be seen a small erosion.
Chronic atrophic gastritis in endoscopic performance is: ① color fades gastric mucosa, showing pink, sallow, heavy person was gray or gray-blue. Can diffuse, but also showed the limitations of patchy distribution; ② submucosal blood vessels prominent. Shrinkage of the initial mesh can be seen a dark red mucosa of small blood vessels, severe mucous membrane shows a larger blue veins dendrite; ③ mucosal folds small or even disappear; ④ When the neck glands associated with atrophic gastritis or intestinal epithelial hyperplasia of of Health, the mucosal surface, rough, granular, or nodular; ⑤ mucosal atrophy fragility, easy bleeding, and may have erosive lesions.
