This proposal is to contribute to data registry and sample bank called Pediatrics Biorepository for Gastroenterology Clinical Research. Samples collected in this study may be used for future research which plan to advance the state of science in the hopes to develop novel diagnostic approaches and identify therapeutic targets.

The study will compare the effectiveness of endoscopic surveillance and endoscopic eradication therapy (EET) for the management of Barrett's esophagus (BE) and low-grade dysplasia (LGD).

It is well understood that gastroesophageal reflux disease (GERD) is a serious health condition.1 GERD, which often manifests as heartburn or regurgitation, is a chronic disorder associated with substantial morbidity and has a major adverse impact on patients quality of life.2, 3 Currently, there are limited options for GERD patients seeking a surgical option to treat their disease. One option for anti-reflux surgery is the LINX® Reflux Management System.4 The RETHINK REFLUX Registry (Research to further inform thinking about the role of LINX for Reflux Disease) will monitor long-term outcomes in the areas of safety, effectiveness, health economics and healthcare utilization over 10 years post-LINX surgery.
