Iron deciency anemia, post-cricoidal esophageal web and dysphagia are characteristics of Patterson Brown Kelly or Plummer-Vinson syndrome. Sideropenic dysphagia was coined by Waldenstorm. There has been a debate regarding the existence and frequency of esophageal webs in patients with iron deciency anemia.In, literature there is no study that correlates the severity of anemia and severity of the web or stricture.This is a prospective study of 50 patients over a period of 3 years. Through our study we would like to analyse if there is any corelationship especially in developing countries like ours were this study was conducted.
