About Transnasal Endoscopy
TransnasaI endoscopy is a non-sedated endoscopic procedure currently available for the surveillance and management of eosinophilic esophagitis. This procedure has been shown to be safe, tolerable and effective in identifying esophageal pathology1.
The advantages of this procedure include minimal time without food or water prior to the procedure, no general anesthesia, faster recovery and the ability to evaluate the esophagus after reintroduction of a single food.
Patients are eligible for this procedure if they are older than 10 years of age, do not have nasal deformities and have an established diagnosis of eosinophilic esophagitis. If you are interested in having a family member or know of someone who is interested in having a family member undergo this procedure, please contact your allergist or pediatric gastroenterologist to make this arrangement. Your referring provider will need to contact me directly to arrange this procedure.
Once I have reviewed your records with your referring provider, I will contact you personally to review your interest and eligibility. If we decide to move forward I will have my scheduler contact you to arrange the procedure
