Esophageal stents are stents used for the treatment of esophageal strictures, esophageal-tracheal fistulas, and severe esophageal reflux. Esophageal stents are classified as bare stents, semi-naked stents and coated stents, which are made of metal or plastic, and are mainly used for the treatment of digestive diseases, such as esophageal stenosis, esophageal-tracheal fistula, and severe esophageal reflux. Esophageal stents can be delivered to the location of the lesion through the gastroscope, and can be expanded in the location of the lesion to play the expected role. Depending on the disease, different stents may be used. For example, in patients with esophageal tracheal fistula, a fully coated stent may be used to block the fistula and prevent reflux from entering the airway, causing the patient to choke and cough. Overall, the majority of patients can significantly improve their discomfort and quality of life after the placement of an esophageal stent, so it is recommended to place an esophageal stent if indicated, and consult a medical professional for specific advice.
