Reflux gastritis is a disease in which the contents of the stomach and duodenum flow back into the esophagus, causing inflammation of the esophagus. It is often mistaken for stomach pain and manifests as heartburn, retrosternal pain, acid reflux and regurgitation, and difficulty in swallowing, with symptoms worsening after eating and at night. It affects the patient’s eating and sleeping, and is painful and unbearable. The progression of the disease can cause esophageal strictures, ulcers, and even gastrointestinal bleeding, and in severe cases, it can develop into esophageal disease. Generally speaking, there are 5 types of cases that require surgery: 1. moderate to severe reflux esophagitis, where the symptoms and esophagitis are still severe after medical treatment; 2. long-standing esophageal ulcers and bleeding; 3. combined esophageal hiatal hernia; 4. young people who need long-term medication; 5. recurrent peptic esophageal strictures, etc.
