Esophagitis, also called esophagitis, is most commonly an inflammation of the esophagus due to gastric and esophageal reflux. The reflux of gastric contents into the esophagus causes damage to the mucosa of the esophagus. In mild cases, symptoms such as edema and congestion or damage that can be seen only under a microscope, or in severe cases, the breakage of the mucosa and even ulcers can be seen with the naked eye under a gastroscope. The main symptoms of reflux esophagitis include heartburn, acid reflux, and chest pain. Symptoms of esophagitis tend to recur. Patients with esophageal stricture may have difficulty swallowing, and occasional gastrointestinal bleeding may occur when ulcers involve blood vessels, but it is relatively rare.

Proton pump inhibitors have a stronger and longer-lasting acid-suppressing effect. At present, these drugs are commonly used clinically, such as omeprazole and tolazol; H2 receptor blockers such as famotidine and cimetidine can also reduce gastric acid secretion, but they are mostly used for maintenance medication or symptomatic treatment. Gastroesophageal reflux is also a power disorder disease, often accompanied by the weakening of gastric power or esophageal power abnormalities, can apply prokinetic drugs such as domperidone, mosapride, itopride, etc.; aluminum thioglycollate, magnesium aluminum carbonate can adhere to the mucosal surface as a physical barrier to reduce its damage to the mucosa. 3, treatment of complications: common complications of gastroesophageal reflux are esophageal stricture, Barrett’s esophagus, etc.. According to the situation, endoscopic treatment or surgical treatment can be chosen.
