Natural History of Eosinophilic Esophagitis

Fast for 4 hours prior to the Esophagram (upper GI x-ray). You will drink a liquid that has barium or another contrast agent in it. The radiologist will use the X-ray machine to look at your upper GI tract while you drink the contrast liquid. The x-ray exam should take between 10-15 minutes.

Subjects will swallow the EsophaCap, which has a string attached, 10 minutes later it has devolved in the stomach. The PI will pull the string to remove the EsophaCap. We will send the sponge for cytology assessing the histologic results of eosinophils per high power field (phf)

Complete the modified Mayo dysphagia Questionnaire (MDQ) and the Eosinophilic Esophagitis Activity Index (EEsAI) at time of physical exam visit with PI.
