Abstract
When to Perform pH-impedance Monitoring and High Resolution Esophageal Manometry (HRM) in Gastroesophageal Reflux Disease?
Highlights
The High Resolution Esophageal Manometry exam is performed by the transnasal introduction of a catheter with a number of sensors ranging from 24 to 36, depending on the technology
It is irreplaceable in ascertaining the existence and the severity of esophagitis and its complications
High Resolution Esophageal Manometry (HRM) Esophageal Manometry: It allows the study of the functional motility alterations that are at the base of the prevention of gastroesophageal reflux
Summary
Esophageal gastroduodenoscopy evaluates mucosal damage and the possible presence of hiatal hernia. In having the 6 channel Impedance Catheter, the exam allows the detection of the reflux exposure time and height in the esophagus, critical data from a clinical and therapeutic point of view. The High Resolution Esophageal Manometry exam is performed by the transnasal introduction of a catheter with a number of sensors ranging from 24 to 36, depending on the technology. This allows for a complete study of the swallowing phase while keeping the probe in the same position, with the result of obtaining:. Even non propagated or simultaneous peristaltic waves are proportionately linked to the severity of the disease
