Endoscopists systematically undersample patients with long-segment Barrett's esophagus: an analysis of biopsy sampling practices from a quality improvement registry

摘要

Background and Aims: Guidelines recommend systematic biopsy sampling in Barrett's esophagus (BE) to reduce sampling error. Adherence to this biopsy sampling protocol has been suggested as a quality indicator; however, estimates of adherence are not available. Using a national registry, we assessed adherence and identified predictors of adherence to biopsy sampling protocols.
