ENDOSCOPY AND BIOPSY TO DIAGNOSE EOSINOPHILIC ESOPHAGITIS
Diagnosis of EoE is made by endoscopy and biopsy. An endoscopy is a medical procedure that allows your doctor to look inside the digestive tract. A thin, flexible, lighted tube called an endoscope is guided into the mouth and throat, then into the esophagus, stomach, and duodenum (beginning of the small intestine). The endoscope allows your doctor to view the inside of these organs. They can also feed instruments through the scope to remove a small sample of tissue. Viewing this biopsy, the doctor takes an average of the number of eosinophils that can be seen in one microscope frame. A high number, such as 15 or more, would indicate EoE.
