The most common cause of choking in the elderly is the slow peristaltic emptying of the esophagus, which can be caused by eating dry or hard food. If the condition occurs even after eating liquid food or semi-liquid food, the possibility of esophageal stricture or esophageal cancer should be ruled out and an electronic gastroscopy should be done to clarify. If gastroscopy clearly indicates esophageal cancer, it is necessary to clarify whether there is metastasis in the surrounding tissues as soon as possible, and if there is no metastasis, go to general surgery for surgical removal as soon as possible. If the esophageal stricture is found to have involved the whole lumen and there is distant metastasis, the effect of surgery is not very good, so it is necessary to put a radioactive stent in the esophagus for treatment, and if necessary, a gastric tube can be put to provide nutrients.
