Esophageal diseases mainly include benign diseases and malignant diseases. Benign diseases mainly refer to reflux esophagitis, esophageal erosion, esophageal diverticulum and esophageal polyps, while malignant diseases mainly include esophageal cancer, esophageal lymphoma, etc. For screening of esophageal diseases, it is mainly to carry out imaging examination of upper digestive tract with iodine water or barium to understand whether there is any possibility of related diseases. If the diagnosis needs to be confirmed, gastroscopy should be performed. When gastroscopy is performed, lesions in the relevant parts of the esophagus can be found, and tissue biopsy under gastroscopy can be performed, and sent to pathological examination to determine whether it is benign or malignant, and then further treatment can be carried out.
