Scarring stricture is very difficult to treat in clinical practice. Esophageal or gastric strictures can cause many symptoms such as dysphagia, and malnutrition, which seriously affects the quality of patients’ life[12-13]. It is especially important to choose the appropriate therapy plan in time to reduce complications and mortality. In recent years, endoscopic therapy has become the optimal therapy method for benign esophageal strictures. Corrosive esophageal stricture is common with complex stenosis. For esophageal strictures, endoscopic therapies include dilatation, stent placement, endoscopic dissection, medication, and cell transplantation, all of which can relieve dysphagia.
