Plummer-Vinson syndrome

Iron-deficient dysphagia is a thin diaphragm in the esophagus cavity, which is divided into upper esophageal web, middle esophageal web, and lower esophageal web according to different parts of the esophagus. Most patients with esophageal webs are asymptomatic and are found during a physical examination or occasional gastrointestinal angiography. A few can be manifested as dysphagia, which can occur in both men and women, and domestic reports are rare.
