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).
Functional Lumen Imaging Probe. 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 ...
Esophageal spasm is a disorder of motility of the esophagus. [2] There are two types of esophageal spasm: [2] Diffuse or distal esophageal spasm (DES), where there is uncoordinated esophageal contractions. Nutcracker esophagus (NE) also known as hypertensive peristalsis, where the contractions are coordinated but with an excessive amplitude.
Frequency. Unknown. 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 ...
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 ...
Esophageal pH monitoring is performed for 24 or 48 hours and at the end of recording, a patient's tracing is analyzed and the results are expressed using six standard components. Of these 6 parameters, a pH score called Composite pH Score or DeMeester Score has been calculated, which is a global measure of esophageal acid exposure. A Demeester ...
Heller myotomy is a surgical procedure [1] in which the muscles of the cardia (lower esophageal sphincter or LES) are cut, allowing food and liquids to pass to the stomach.It is used to treat achalasia, a disorder in which the lower esophageal sphincter fails to relax properly, making it difficult for food and liquids to reach the stomach.
Esophageal achalasia is an esophageal motility disorder involving the smooth muscle layer of the esophagus and the lower esophageal sphincter (LES). [5] It is characterized by incomplete LES relaxation, increased LES tone, and lack of peristalsis of the esophagus (inability of smooth muscle to move food down the esophagus) in the absence of ...
