The main treatments for esophageal stricture are endoscopic dilatation and stent dilatation. Esophageal stenosis refers to the inflammation and scarring of the esophagus due to various reasons, which ultimately leads to the narrowing of the esophagus and the inability of food to pass through, and the main clinical manifestations are difficulty in swallowing, pain when swallowing, weight loss and food reflux after meals, and so on. Endoscopic dilatation and stent dilatation are the main treatments for esophageal stricture. Endoscopic dilatation includes probe dilatation and balloon dilatation. 1. Tube dilation: A hard, tapered instrument called a dilator is inserted into the narrowed esophagus, and after a few days or weeks, a series of wider dilators are used to gradually widen the esophagus. This method is less commonly used today. 2. Balloon dilation: A balloon that can be filled with air or water is inserted into the esophagus. The balloon is filled with air or water to treat the scarred stricture. However, it is important to be careful about the degree of dilatation and requires endoscopic treatment by a specialized endoscopist. 3. Stent dilatation: A stent made of memory alloy is placed in the stenosis area and the esophagus is dilated for 24-72 hours to slowly expand the stenosis. These three methods need to be repeated several times, sometimes every six months or a year when symptoms recur. If the dilation treatment is not effective, surgery is needed to remove the scar tissue.
