Esophageal polyps are proliferations of esophageal mucosal tissue, which are benign tumors of the esophagus and can be divided into five types: true mucosal polyps, fibrous polyps, mucinous fibromas, lipomas, and fibromyomas. The cause of esophageal polyps is chronic inflammation of the esophagus. When esophageal polyps are small, there is no symptom, but with the growth of polyps, clinical symptoms will gradually appear, such as squeezing the esophageal space and affecting food swallowing, difficulty in swallowing, vomiting, reflux symptoms causing bleeding and black stool. When esophageal polyps grow to a certain extent, most of the esophagus will be blocked because of the friction caused by eating and food constantly causing polyp ulcers, bleeding and black stools, and compression of the esophagus causing coughing, breathing difficulties and other upper respiratory symptoms, esophageal polyps are treated by surgical removal.
