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.
Acid perfusion test, also called the Bernstein test, is a test done to reproduce the pain when the lower esophagus is irrigated with an acid solution in people with GERD (gastroesophageal reflux disease). [1] There will be a negative result in normal people, but a false positive reading may be seen in up to 15% of people. [2]
GERD or acid reflux can also contribute to snoring by causing esophageal tissue to swell, partially blocking the airway. "Elderly adults may also develop weakness of the muscles of the palate and ...
Acid reflux is due to poor closure of the lower esophageal sphincter, which is at the junction between the stomach and the esophagus. Diagnosis among those who do not improve with simpler measures may involve gastroscopy, upper GI series, esophageal pH monitoring, or esophageal manometry. [6]
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 odds are high you’ve had a cough before in your life, but each time can throw you for a loop. Even though you’ve been through this, it can be hard to know when to see a doctor for a cough ...
A complete 24-hour profile of gastric acid secretion is best obtained during an esophageal pH monitoring study. Achlorhydria may also be documented by measurements of extremely low levels of pepsinogen A (PgA) (< 17 µg/L) in blood serum. The diagnosis may be supported by high serum gastrin levels (> 500–1000 pg/mL). [8]
