Arm Intervention/treatment
Experimental: Cytosponge/ brushing Device: Cytosponge - Brushing
  • Patients with eosinophilic esophagitis will be enrolled. Undergoing clinically indicated endoscopy and biopsy either for initial diagnosis or for monitoring the activity of their disease.
  • Two hours prior to endoscopy in the patients will be asked to swallow the Cytosponge. Briefly, the capsule and bunched up string are swallowed with water.
  • The string is held without any tension to allow the capsule to move into the stomach. The patient holds onto the string for five minutes after ingestion to allow the capsule to dissolve in the proximal stomach, where a spherical mesh of 3 cm diameter is released.
  • The back of the throat is then sprayed with 1% lidocaine and the expanded mesh withdrawn by pulling on the string with the patient's head in an extended position.
  • Following this, the clinically indicated endoscopy will be performed. Prior to biopsies we will do a brushing of the esophagus.
