    • Esophageal function testing - ASGE

      Esophageal function testing can be a useful adjunct for the evaluation of upper GI tract symptoms. The current technology includes conventional and high-resolution ma-nometry (HRM), and multichannel intraluminal imped-ance (MII) and pH monitoring, which measure esophageal intraluminal pressure, bolus transit, and pH, respectively.

The probe was then inserted in a transnasal manner through the esophagus into the stomach and the esophageal pH sensor was positioned at 5 cm above the upper limit of the LES. The design of the probe allowed measurement of impedance data at 3, 5, 7, 9, 15, and 17 cm above the LES.
