Reflux gastritis surgery

Alkaline reflux gastritis usually occurs 1 to 2 years after major gastrectomy. It is generally believed that due to the loss of the pyloric sphincter, bile continues to flow back into the stomach. The bile salts and lysolecithin in it destroy the gastric mucosal barrier and A large number of hydrogen ions in the gastric juice reversely penetrated, prompting mast cells to release histamine, causing gastric mucosal hyperemia, edema, inflammation, bleeding, erosion and other lesions. Its clinical manifestations are typical triads: ① persistent burning pain under the xiphoid process, which worsens after eating, and the antacid is ineffective; ② bile vomiting, pain after vomiting remains; ③ weight loss. In addition, there is still anemia caused by a small amount of bleeding, low or no acid in gastric juice. Severe cases should be treated surgically.
