There are occasional cases of stent dislocation in clinic, but it is not common. Stent placement for esophageal cancer is applicable to patients with advanced stage of esophageal cancer, no indication for surgery and with difficulty in eating. The main purpose of stenting is to widen the narrowed esophageal lumen, so that patients can regain the ability to eat, ensure nutritional intake and improve the quality of life. After stenting, patients need to pay more attention to their diet. Eating spicy and stimulating foods, rough and hard foods may cause the stent to fall off, and the stent falling off is also related to the location of the stent and the size of the stent, but it is not rare to see stent falling off in clinical practice. Whether the stent will fall off or not cannot be generalized, and needs to be determined in the light of the actual situation.
