If the friction after the installation of esophageal stent causes localized erosion of the esophagus, it is necessary to use anti-inflammatory drugs for local treatment and to reduce the friction by adjusting dietary habits. 1. Anti-inflammatory treatment: After the installation of esophageal stent, the long-term friction on the surface of the esophagus may cause inflammation or injury, resulting in the formation of localized erosion on the surface of the esophagus. Therefore, for this kind of erosion, it is generally recommended to choose anti-inflammatory drugs, such as aspirin, acetaminophen, etc. for targeted use, which can effectively relieve the inflammation and erosion of the mucosal surface. 2. Adjustment of diet: It is recommended to adjust the diet appropriately after the installation of esophageal stent. Don’t eat too hard food, and don’t eat too much food at one time or eat too fast, otherwise it will increase the friction of the stent on the surface of the esophagus, which will cause erosion. After the installation of esophageal stent friction caused by localized esophageal erosion, should be under the guidance of the doctor to choose the appropriate drugs for targeted use.
