Overview
Other diagnostic finding present in heartburn and consistent with diagnosis of gastroesophageal reflux disease (GERD) is the presence of acidic reflux in the esophagus through the ambulatory reflux monitoring. The 12 lead ECG may be used if heartburn due to cardiac causes is suspected.
Other diagnostic studies
Ambulatory reflux monitoring
- GERD is mostly diagnosed clinically by the presenting typical symptoms which include heartburn, regurgitation, and dysphagia.
- Correlation of the GERD symptoms with confirmed acid presence by the ambulatory reflux monitoring is strongly suggestive of GERD.
- Ambulatory reflux monitoring is recommended by the American College of Gastroenterology (ACG) as the only laboratory test to determine the presence of acidic reflux in the esophagus.[1]
- Indications of ambulatory reflux monitoring include the following:[2]
- GERD diagnosis if it is not confirmed
- Determine the time of reflux occurrence
- Refractory GERD symptoms
- Preoperative for non-erosive disease
- Ambulatory reflux monitoring is performed in either two ways which include:
- Telemetry capsule (48 hours monitoring)
- Transnasal catheter (24 hours monitoring)
Manometry
In this test, a pressure sensor (manometer) is passed through the mouth into the esophagus and measures the pressure of the lower esophageal sphincter directly.
Biopsy
A small sample of tissue from the esophagus is removed. It is then studied to check for inflammation, cancer, or other diseases.
