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).
Anorectal manometry (ARM) is a medical test used to measure pressures in the anus and rectum and to assess their function. [1][2] The test is performed by inserting a catheter, that contains a probe embedded with pressure sensors, through the anus and into the rectum. [3] Patients may be asked to perform certain maneuvers, such as coughing or ...
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 ...
High-resolution manometry. This figure shows a pressure topography plot during a normal swallow, measured using a 36-channel high-resolution manometry system. Time is on the horizontal axis and length along the esophagus on the vertical axis. Pressure magnitude is encoded in color corresponding to the scale shown at the bottom.
The diagnosis is made by an esophageal motility study (esophageal manometry), which evaluates the pressure of the esophagus at various points along its length. The term "nutcracker esophagus" comes from the finding of increased pressures during peristalsis , with a diagnosis made when pressures exceed 180 mmHg; this has been likened to the ...
An esophageal motility disorder (EMD) is any medical disorder resulting from dysfunction of the coordinated movement of esophagus, which causes dysphagia (i.e. difficulty in swallowing, regurgitation of food). [1] Primary motility disorders are: [1] Achalasia. Diffuse esophageal spasm. Nutcracker esophagus. Hypertensive lower esophageal sphincter.
Esophageal achalasia. Anorexia (but willing and trying to eat), inability to swallow food, chest pain comparable to heart attack, lightheadedness, dehydration, excessive vomiting after eating (often without nausea). 829 in a period of 1–8 years study out of a 28 demographic, 754 million record pool.

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 ...
