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.
Diffuse esophageal spasm (DES) is a motility disorder characterized by recurrent episodes of chest pain or dysphagia as well as nonpropulsive (tertiary) contractions on radiographs. [ 5 ] Nutcracker esophagus is characterized by high-amplitude peristaltic contractions that are frequently prolonged and cause dysphagia and chest pain.
An EMS is typically done to evaluate suspected disorders of motility or peristalsis of the esophagus. These include achalasia, diffuse esophageal spasm, nutcracker esophagus and hypertensive lower esophageal sphincter. These disorders typically present with dysphagia, or difficulty swallowing, usually to both solids and liquids even initially.
Nutcracker esophagus is characterized as a motility disorder of the esophagus, meaning that it is caused by abnormal movement, or peristalsis of the esophagus. [2] People with motility disorders present with two main symptoms: chest pain or difficulty with swallowing. Chest pain is the more common.
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]
Diffuse esophageal spasm (DES), also known as distal esophageal spasm, is a condition characterized by uncoordinated contractions of the esophagus, which may cause difficulty swallowing or regurgitation. In some cases, it may cause symptoms such as chest pain, similar to heart disease. In many cases, the cause of DES remains unknown.
The ridge in the upper part of the picture is the high pressure of the upper esophageal sphincter which only opens for a short time to let water pass. Peristalsis ( / ˌ p ɛr ɪ ˈ s t æ l s ɪ s / PERR -ih- STAL -siss , US also /- ˈ s t ɔː l -/ - STAWL - ) [ 1 ] is a type of intestinal motility , characterized by radially symmetrical ...
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 ...
