If patients with esophageal cancer cannot eat in the middle or late stage, they can generally choose the following methods: firstly, they can undergo interventional stenting surgery for esophageal cancer, which can support the blocked esophagus with a stent and then provide a proper liquid diet to help patients solve the problem of eating. In the second method, local radiotherapy or chemotherapy can be used to completely or partially kill the local enlarged or invasive esophageal cancer, which can also reduce the problem of esophageal stricture and indirectly solve the problem of eating. The third method is to directly enter the gastrointestinal tract through the gastrostomy tube with the chyme or food soup, which can effectively alleviate the situation that esophageal cancer cannot eat and does not want to eat.
