Abstract:
Multichannel intraluminal impedance is a relatively new technology that allows detection of bolus movement in the gastrointestinal tract without the use of radiation. In clinical applications it is combined with manometry, allowing a better evaluation of the functional characteristics (ie, bolus transit) of esophageal motility abnormalities. When combined with pH monitoring, it provides more comprehensive data on both acid and nonacid gastroesophageal reflux.

Esophageal Strictures-I: Introduction
Etiology
The primary cause of esophageal strictures is long-standing gastroesophageal reflux disease (GERD), accounting for about 70 to 80% of adult cases. Chronic acid reflux can lead to injury and scarring of the esophageal lining, culminating in...
