Dynamic position versus 24-hour pH testing for detection of esophageal acid reflux disease

Dynamic position testing for the detection of esophageal acid reflux disease

Currently the most widely accepted study for the detection of significant esophageal reflux disease is the 24-hr pH study. It is a problematic study, however. The data obtained from that study have to be analyzed by comparison to a normal tested population, revalued through a weighted scale, then judged against recorded symptoms in order to obtain a valid interpretation. Dynamic position acid reflux testing has recently been described as a better alternative. In this comparative study between dynamic position and 24-hr pH testing in 64 patients, the dynamic position study was found to be more definitive, more informative, and more efficient in the detection of significant esophageal acid reflux disease.
