Mild esophageal mucosal injury generally has no obvious sequelae after cure, while severe cases may have sequelae such as esophageal stenosis after surgical treatment. Mild injury can be orally taken to protect the mucosa, inhibit gastric acid drugs, such as aluminum magnesium carbonate chewable tablets, omeprazole and so on. Meanwhile, through the adjustment of diet, slowly recover. After this kind of injury is cured, there is generally no obvious sequelae. If the esophageal injury forms a perforation or rupture of the esophagus occurs, after surgical treatment, there is a possibility of scar tissue proliferation, which may lead to esophageal stenosis, dysphagia and other symptoms. Therefore, esophageal mucosal injury needs early and timely treatment, and early treatment is very critical to the prognosis. The medication should be administered under the guidance of a doctor.
