You may have access to experimental treatments for eosinophilic esophagitis not available elsewhere, such as Cytosponge to monitor treatment results. Researchers also are studying ways to improve diagnosis and treatment of Barrett's esophagus, including minimally invasive treatments. Barrett's esophagusResearchers are investigating novel imaging techniques to detect early cancer changes in Barrett's esophagus and advanced endoscopy to treat Barrett's esophagus and early cancers. They also are researching medications that can decrease cancer risk and genetic factors that may be related to Barrett's esophagus. Eosinophilic esophagitisMayo Clinic is a leader in eosinophilic esophagitis research and actively researches eosinophilic disorders. Mayo researchers have tested the effects of many medications on treatment, including steroids, asthma medications and acid-blocking medications. Clinical trials are underway to study long-term management and remission of eosinophilic esophagitis. Mayo Clinic researchers also are studying the use of a device called the Cytosponge as a replacement for endoscopy to monitor ongoing treatment for eosinophilic esophagitis. The Cytosponge is a small sponge inside a capsule attached to a string. You swallow the capsule, which dissolves; the doctor then pulls out the sponge, scraping cells off your esophagus. It's quick, inexpensive, minimally invasive and does not require anesthesia. The Allergic Diseases Research Laboratory at Mayo Clinic's campus in Rochester, Minnesota, investigates the mechanisms of common airway and skin diseases. The lab focuses on and studies types of immune cells (white blood cells), especially eosinophils. Laboratories in the areas of clinical immunology and immunotherapeutics, immunology, and gastroenterology and hepatology also are involved in research on eosinophilic disorders.

The patient comes first. So the mission and research here is to advance how we can best help the patient, how to make sure the patient comes first in care. So in many ways, it's a cycle. It can start with as simple as an idea worked on in a laboratory, brought to the patient bedside, and if everything goes right — and let's say it's helpful or beneficial — then brought on as a standard approach. And I think that is one of the unique characteristics of Mayo's approach to research — that patient-centeredness — that really helps to put it in its own spotlight.
