  2. Esophageal motility study - Wikipedia

    en.wikipedia.org/wiki/Esophageal_motility_study

    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).

  3. Esophageal achalasia - Wikipedia

    en.wikipedia.org/wiki/Esophageal_achalasia

    Specific tests for achalasia are barium swallow and esophageal manometry. In addition, endoscopy of the esophagus, stomach, and duodenum ( esophagogastroduodenoscopy or EGD), with or without endoscopic ultrasound , is typically performed to rule out the possibility of cancer. [ 9 ]

  4. Esophagogastric junction outflow obstruction - Wikipedia

    en.wikipedia.org/wiki/Esophagogastric_junction...

    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 with additional ...

  5. Esophageal dysphagia - Wikipedia

    en.wikipedia.org/wiki/Esophageal_dysphagia

    Esophageal cancer also presents with progressive mechanical dysphagia. Patients usually come with rapidly progressive dysphagia first with solids then with liquids, weight loss (> 10 kg), and anorexia (loss of appetite). Esophageal cancer usually affects the elderly. Esophageal cancers can be either squamous cell carcinoma or adenocarcinoma.

  6. Upper gastrointestinal series - Wikipedia

    en.wikipedia.org/wiki/Upper_gastrointestinal_series

    An upper gastrointestinal series, also called a barium swallow, barium study, or barium meal, is a series of radiographs used to examine the gastrointestinal tract for abnormalities. A contrast medium, usually a radiocontrast agent such as barium sulfate mixed with water, is ingested or instilled into the gastrointestinal tract, and X-rays are ...

  7. Nutcracker esophagus - Wikipedia

    en.wikipedia.org/wiki/Nutcracker_esophagus

    The diagnosis of nutcracker esophagus is typically made with an esophageal motility study, which shows characteristic features of the disorder. Esophageal motility studies involve pressure measurements of the esophagus after a patient takes a wet (fluid-containing) or dry (solid-containing) swallow. Measurements are usually taken at various ...

  8. Esophageal pH monitoring - Wikipedia

    en.wikipedia.org/wiki/Esophageal_pH_Monitoring

    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 ...

  9. Gastroesophageal reflux disease - Wikipedia

    en.wikipedia.org/wiki/Gastroesophageal_reflux...

    Barium swallow X-rays should not be used for diagnosis. [42] Esophageal manometry is not recommended for use in the diagnosis, being recommended only prior to surgery. [ 42 ] Ambulatory esophageal pH monitoring may be useful in those who do not improve after PPIs and is not needed in those in whom Barrett's esophagus is seen. [ 42 ]
