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 of the disease to medical or surgical treatment.
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. The impedance–pH monitoring ...
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]
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). [ 1 ] Indications
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 1 ...
Manometry refers to pressure measurement (usually in a medical context), taking forms including: Esophageal manometry, or Esophageal motility study Anorectal manometry
Bernstein test is simple and cheap but mostly obsolete nowadays. Esophageal pH monitoring is the gold standard for GERD. However, the initial management is with proton pump inhibitors. If the patient does not respond to it, and continues to have symptoms of GERD, i.e. heartburn, hoarseness, chronic cough, then 24 hr pH monitoring should be ...
Billroth II, more formally Billroth's operation II, is an operation in which a partial gastrectomy (removal of the stomach) is performed and the cut end of the stomach is closed.
