Eosinophilic Esophagitis

Welcome to the Mayo Clinic Eosinophilic Esophagitis page. EoE is a relatively new diagnosis and is most commonly experienced via food sticking with swallowing in adults. This is a result of an allergic response in the esophagus. We are a leading center for research and clinical care.

Follow this page to read up on news in our EoE clinic, including patient experiences, physician insight, clinical trials and up-to-date research and other useful information about EoE. Post a comment, share your thoughts and be connected.

Using the Cytosponge to Test for Eosinophilia

By Crystal Lavey, @crystallavey

Cytosponge

The upper endoscopy is the gold standard way for doctors to assess your esophagus and take biopsies, or tiny pieces of tissue, to test for eosinophils in your esophagus.

Dr. Rebecca Fitzgerlad of Cambridge University has developed the Cytosponge, a capsule with a string attached, as an alternative way to retrieve esophageal tissue. This tissue can be tested in the same way that biopsies are tested in pathology.

Dr. David Katzka of Mayo Clinic in Rochester is using the Cytosponge to monitor Eosinophilic Esophagitis. Watch the video to learn more about this exciting new testing device.

 

The team anticipates clinical use in the future. To find out more about the Cytosponge and studies available, email eosinophilic@mayo.edu or call Mayo Clinic Rochester at (507) 284-2141.
