Patient Acceptance and Preference Among Screening Modalities for Detection of Barrett's Esophagus

Patient Acceptance and Preference Among Screening Modalities for Detection of Barrett's Esophagus

To assess patient acceptance and preference among screening modalities, Esophagogastroduodenoscopy (EGD), Transnasal Esophagoscopy (TNE), and Cytosponge for Barrett's esophagus (BE). Subjects will undergo administration of Cytosponge and transnasal endoscopy (TNE) prior to their scheduled clinically indicated upper endoscopy performed per routine standard of care. Following the procedure, a follow-up phone call will be made during which an impact of events scale related to the subjective distress of each procedure, a preference and acceptance questionnaire, and adverse events related to study participation will be collected.

Potential subjects will be identified via protocol and Institutional Review Board (IRB) methods prior to obtaining written informed consent. Once written informed consent is obtained and baseline demographic and medical history is collected, subjects will undergo administration of Cytosponge and transnasal endoscopy (TNE) prior to their scheduled clinically indicated upper endoscopy performed per routine standard of care. Following the procedure, a follow-up phone call will be made during which an impact of events scale related to the subjective distress of each procedure, a preference and acceptance questionnaire, and adverse events related to study participation will be collected.

Inclusion Criteria:

• Patients with one of the following: Gastroesophageal Reflux Disease (GERD) OR Barrett's esophagus (BE)
• At least 18 years of age at time of consent
• Able and willing to provide written informed consent
• Able and willing to comply with required study procedures and follow-up schedule
