Esophageal pH monitoring. In gastroenterology, esophageal pH monitoring is the current gold standard for diagnosis of gastroesophageal reflux disease (GERD). It provides direct physiologic measurement of acid in the esophagus and is the most objective method to document reflux disease, assess the severity of the disease and monitor the response ...
Impedance–pH monitoring. Impedance–pH monitoring is a technique used in the diagnosis of gastroesophageal reflux disease (GERD), by monitoring both impedance and pH. [ 1][ 2] Patients with ongoing symptoms while on proton-pump inhibitor (PPI) therapy are commonly diagnosed with impedance–pH monitoring while continuing their medications.
Gastroesophageal reflux disease ( GERD) or gastro-oesophageal reflux disease ( GORD) is a chronic upper gastrointestinal disease in which stomach content persistently and regularly flows up into the esophagus, resulting in symptoms and/or complications. [ 6][ 7][ 10] Symptoms include dental corrosion, dysphagia, heartburn, odynophagia ...
Functional Lumen Imaging Probe ( FLIP) is a test used to evaluate the function of the esophagus, by measuring the dimensions of the esophageal lumen using impedance planimetry. Typically performed with sedation during upper endoscopy, FLIP is used to evaluate for esophageal motility disorders, such as achalasia, diffuse esophageal spasm, etc. [ 1]
The disorder shows peristalsis with high pressure esophageal contractions exceeding 180 mmHg and contractile waves with a long duration exceeding 6 seconds. An esophageal motility study ( EMS) or esophageal manometry is a test to assess motor function of the upper esophageal sphincter (UES), esophageal body and lower esophageal sphincter (LES).
Esophagogastric junction outflow obstruction ( EGJOO) is an esophageal motility disorder characterized by increased pressure where the esophagus connects to the stomach at the lower esophageal sphincter. EGJOO is diagnosed by esophageal manometry. However, EGJOO has a variety of etiologies; evaluating the cause of obstruction with additional ...
ICD-9-CM. 45.13. MeSH. D016145. OPS-301 code. 1-631, 1-632. [ edit on Wikidata] Esophagogastroduodenoscopy ( EGD) or oesophagogastroduodenoscopy ( OGD ), also called by various other names, is a diagnosti. c endoscopic procedure that visualizes the upper part of the gastrointestinal tract down to the duodenum.
High-resolution manometry ( HRM) is a gastrointestinal motility diagnostic system that measures intraluminal pressure activity in the gastrointestinal tract using a series of closely spaced pressure sensors. For a manometry system to be classified as "high-resolution" as opposed to "conventional", the pressure sensors need to be spaced at most ...
