If a patient with esophageal cancer is unable to eat at an advanced stage and needs to have a stent placed, it is already at the end stage of esophageal cancer, which in most cases is 2-3 months, and in good cases, it is hardly more than 6 months. There are many factors that affect this, including the length and size of the esophageal cancer, whether the stent is combined with other treatments after placement, and whether these treatments are effective, and so on. But in general, stents and fistulas are considered only for patients with advanced and end-stage esophageal cancer, who are no longer able to eat. Nowadays, if stents are to be placed, it is recommended to put fully laminated self-expanding metal stents. In addition, there are many adverse side effects for patients, especially the possibility of bleeding.
