About the study

This study plans to learn if the EvoEndo Endoscopy system can be used to evaluate, provide and follow up care for upper gastrointestinal tract diseases in the bariatric population. The smallest current scope available for such a technique is an adult transnasal endoscope with a larger diameter, a pulmonary bronchoscope or Ear Nose and Throat (ENT) laryngoscope. This study is evaluating a newly Food and Drug Administration (FDA) cleared ultra-slim, single-use, endoscope specifically designed for transnasal endoscopy to evaluate its use in adult upper tract gastrointestinal diseases. If such a technique is successful it could improve the safety, cost, and access of endoscopic care for patients in need of an endoscopic evaluation for a bariatric medical condition.
