Study of Endoscopic Barrett's Esophagus Diagnosis
Study Details
Study Description
Brief Summary
Barrett's esophagus (BE) is a condition that often occurs in patients who have had GERD for a long time. The researchers are interested in BE because it can sometimes become a cancer in the esophagus. The way that we currently diagnose BE is by performing an upper endoscopy and looking for a change in the color of the esophagus. This color change may represent BE. If the doctor sees this, he/she may take biopsies of this area.
Studies have shown that making the diagnosis of BE can be hard to make. One of the reasons why this may be is because doctors may interpret what they see differently during the procedure. In other words, they may see an esophagus that appears normal in color or abnormal in color.
The purpose of this study is to compare two doctors' impressions of the appearance of the esophagus during a single endoscopy procedure.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| 1 Study participants must be older than 18 years of age who are having an endoscopy performed to evaluate symptoms of GERD such as heartburn, acid taste in the mouth, dysphagia, dyspepsia, or those who are having a screening/surveillance exam for BE. |
Outcome Measures
Primary Outcome Measures
- The primary outcome will be the interobserver variability in the presence of columnar epithelium as well as the measured lengths. [one endoscopy visit]
Secondary Outcome Measures
- frequency of pathology-confirmed BE [one endoscopy visit]
- variables that predict endoscopic interobserver agreement and path-confirmation [one endoscopy visit]
