The choice of esophageal stent is very important, and it is important to choose the right length and thickness of endoesophageal stent according to the patient’s condition, so that the patient can feel more comfortable after stenting and can better achieve good results. The length of the stent should generally be 1-2 cm longer than the stenotic segment, and for stenosis formed by benign lesions or for esophageal anastomotic stenosis, self-expanding metal endoprostheses are mostly used, which can reduce the cost. For malignant stenosis of the esophagogastric anastomosis, a self-expanding metal endoprosthesis with membrane anti-reflux is generally used to prevent acid reflux as well as reflux of food. For patients with mid- to late-stage esophageal cancer who have lost the chance of surgery, or for patients with malignant stenosis who are old and frail and unwilling to operate, or for patients with anastomotic scar cancer and tumor recurrence, endoprostheses with membrane fine mesh or stents carrying radioactive particles should be used to prevent the tumor from growing into the tissue and causing restenosis.
