About this study
Official title: Population Based Screening for Barrett's Esophagus in Olmsted County : A Pilot Study
To compare participation rates in screening for Barrett's Esophagus (BE) using sedated esophagogastroduodenoscopy (EGD), unsedated transnasal endoscopy and capsule endoscopy in a population based cohort. An age and gender stratified random sample of 300 patients from a previously defined (in terms of the presence or absence of symptoms of gastroesophageal reflux using a validated questionnaire) population based cohort from Olmsted County11, 12 using the Rochester Epidemiology Project (REP), who have not undergone endoscopy, will be randomized to undergo screening using capsule endoscopy OR transnasal endoscopy OR conventional sedated endoscopy. The investigators will compare participation rates in the three arms.
To identify factors associated with non-participation in population screening for BE. The investigators will compare demographic and clinical factors in participants and non-participants, to help predict non-participation using data from prior surveys (data has been collected on patient demographics, bowel and reflux symptoms, employment, education, somatization behavior, psychological profiles using the validated Gastroesophageal Reflux questionnaire [GERQ] and the Bowel Disease Questionnaire [BDQ]) which have been completed by all targeted subjects. This preliminary will allow us to identify barriers to screening and develop interventions to increase participation in future larger studies.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
| Study group | Role | What they receive |
|---|---|---|
| 1 EGD | Olmsted county residents with no history of Barrett's esophagus,who have previously completed GERQ questionnaire, randomized to EGD. | |
| 2 Transnasal | Olmsted county residents with no history of Barrett's esophagus,who have previously completed GERQ questionnaire, randomized to Transnasal endoscopy. | |
| 3 PillCam | Olmsted county residents with no history of Barrett's esophagus,who have previously completed GERQ questionnaire, randomized to PillCam. |
What is being measured
The primary outcome is the main question the study is designed to answer.
The primary outcome variable for this aim will be the number of subjects in each group that need to be contacted until 20 in each group agree to participate in this study.
Measured: one year
Secondary outcomes (1)
To access variables for prediction of non-participation: age, gender, education level, employment, marital status, esophageal symptoms
Measured: one year
