GERD—even more complicated than you thought

Carlson et al. present a study published in Neurogastroenterology and Motility in which they utilized the EndoFLIP^® device (Crospon, Galway Ireland) to evaluate the esophageal response to distention among 25 patients who had previously undergone esophageal pH monitoring while off acid suppression medications (1). FLIP is short for functional luminal imaging probe technology. Esophageal reflux was measured by the acid exposure time (AET).
