 Esophageal stenosis may develop because of various causes, and cases of stenosis are normally subdivided into “malignant” and “benign” types or into “functional” or “fixed” stenosis. Malignant stenosis cases are most often caused by esophageal cancer, but are occasionally caused by metastasis of lung or breast cancer to the esophagus or metastasis to mediastinal lymph nodes. Furthermore, there are cases of stenosis caused by esophageal invasion. Fixed stenosis is a type of benign stenosis caused by reflux esophagitis, corrosive esophagitis, and postoperative scar tissue following methods such as endoscopy. There are various functional stenoses caused by functional disorders of the esophagus, as most prominently exemplified by esophagus achalasia ; furthermore, esophageal webs and congenital esophageal stenoses have been observed. Endoscopy and contrast imaging are generally used to observe esophageal stenosis ; however, a conclusive diagnosis can only be established through a comprehensive approach.
