1 progression of impedance changes from distal to proximal indicate a retrograde bolus
movement as observed in reflux (see Figure 2b). In order to detect these changes, MII …

Esophageal ambulatory pH impedance monitoring showed much promise in the new
millennium as a novel approach to quantifying reflux events irrespective of pH or …

282 extent of esophageal acid exposure in patients with gastroesophageal reflux disease
(GERD) with typical or atypical symptoms, patients who are candidates for surgical …

Figure 1. Schematic representation of MI and MII catheter.(a) Two 2-mm–long impedance
sensing electrodes positioned 1 mm from the tip of a 2-mm soft catheter were advanced …

Background: Toward more understanding esophageal motility disorders it is important to
have data about bolus movement together with associated peristalsis. In previous studies …

Multichannel intraluminal impedance (MII) is a new technique available for the evaluation of
esophageal bolus transit and reflux similar to barium swallow, but without the hazards of …

Background: Twenty-four-hour multichannel intraluminal impedance and pH (MII-pH)
esophageal monitoring allows detection of both acid and nonacid gastroesophageal reflux …

Impedance monitoring was first proposed as a method for gastrointestinal motility 10 yr ago.
It detects changes in resistance to current flow when a bolus traverses an electrode pair, and …

Background: Some patients exhibit low DBI because of fluid retention in the esophagus or
acute or chronic mucosal changes. Low DBI can make MII-pH difficult to interpret. Study: We …

Intraluminal impedance monitoring is a new technique that can be used to detect the flow of
liquids and gas through hollow viscera. In combination with manometry, it is used for …
