Utility of Mucosal Impedance Device in Chronic Esophageal Disorders:

Background \& Significance Chronic benign esophageal disorders such as Gastroesophageal reflux disease (GERD) and eosinophilic esophagitis are common gastrointestinal disorders affecting nearly 20% and 0.1% of the population, respectively. Although these conditions are frequent, the diagnosis of GERD or EoE requires complex decision making involving endoscopic examination, histopathological examination, and esophageal pH testing. This translates into significant economic burden; For example, burden due to GERD is about $24 billion annually. Additionally, there may be a delay in the diagnosis of GERD or EoE as Investigators might have to do multiple procedures such as upper endoscopy, esophageal pH testing, etc for the same participant for confirmation of the diagnosis. In addition, there could be overlay between GERD and EoE in the diagnosis which make cause delay in the diagnosis and decision making. Aim: Here, Investigators will plan to identify the diagnostic utility and cost-effectiveness of this novel Mivu device(FDA approved) in the diagnosis of gastroesophageal reflux disease or chronic esophageal inflammatory disorders in participants with reflux symptoms or chronic esophageal symptoms.
