After six months of radiotherapy for esophageal cancer, the patient can undergo esophageal dilatation, esophageal stenting or nutrient tube under doctor’s guidance. 1. Esophageal dilatation: The continued growth of esophageal tumor cells will make the esophagus narrow, in addition, inflammation, edema and scarring after radiotherapy will cause further narrowing of the esophagus, so esophageal dilatation can be performed endoscopically to help relieve the symptoms. 2. Esophageal stenting: If the esophagus becomes narrow again after endoscopic esophageal dilatation, esophageal stenting can be considered. 3. Nutritional tube: If the degree of esophageal stenosis is very serious, nutritional tube, such as nasogastric tube, nasojejunal nutritional tube, etc., can be considered to be placed to give enteral nutrition to ensure the nutritional status of patients. If the patient has esophageal stenosis half a year after radiotherapy for esophageal cancer and can’t eat, he/she should seek medical treatment in time, improve relevant auxiliary examination, such as gastroscopy, etc., so as to make clear the situation of the tumor, and then deal with it in a targeted way.
