Some patients with gastroesophageal reflux disease do not pay enough attention to their disease, do not have regular diet, and do not receive effective treatment, delaying the disease, and eventually cause esophageal scar stenosis. What is esophageal scar stenosis.

　　Esophageal scar stenosis, as the name suggests, refers to the long-term stimulation of the esophagus, epithelial injury, repair, re-injury, re-repair, and so on, eventually leading to scar at the lower end of the esophagus. Alleged stimulation is gastric content content, include food residue, bile, gastric acid to wait, by the reflux inside the stomach and on, reach esophagus, injure esophagus mucous membrane. Scars, unlike skin, are known to be somewhat stiff to the touch, almost inelastic, and protruding above the surface of the skin. This is also the case with scarring in the esophagus, which is prominent and growing larger at the lower end of the esophagus.

　　Esophageal X - ray barium meal examination is one of the effective examination methods of esophageal scar stenosis, can clearly show the location, degree and scope of stenosis lesions. The esophageal cavity is generally observed to be narrow, with irregular edges and uneven thickness. Generally, the stricture caused by gastroesophageal reflux disease is usually located in the lower esophageal segment, the lesion scope is relatively limited, and the course of disease is long. Because gastroesophageal reflux disease can cause esophageal cancer, in order to determine whether there is cancer, it is necessary to do pathological tissue biopsy of the lower esophageal segment, take a piece of tissue through gastroscopy and observe whether the cells are cancerous under the microscope. Pathological examination is the gold standard for the diagnosis of esophageal cancer. For patients with esophageal scar stenosis, gastroscope esophageal dilatation is generally adopted in clinical practice, and long-term proton pump inhibitor maintenance therapy is given after surgery, which can effectively prevent recurrence of stenosis. For a few patients with severe esophageal scar stenosis, surgical treatment is necessary.

　　Originally gastroesophageal reflux disease is relatively good to cure, we recommend timely treatment, follow the doctor's arrangement to take medicine on time, it is best not to develop to the point of esophageal scar stenosis.
