Barium swallow in nutcracker esophagus is also typically normal, [2] but may provide a definitive diagnosis if contrast is given in tablet or granule form. Studies on endoscopic ultrasound show slight trends toward thickening of the muscularis propria of the esophagus in nutcracker esophagus, but this is not useful in making the diagnosis.
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. [6]
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.
Other potential tests include an esophagram (or barium swallow), which involves swallowing a contrast solution and tablet to examine the anatomy of the esophagus and mortality of the esophagus and ...
These contractions are suspect in esophageal dysmotility and present on a barium swallow as a "corkscrew esophagus". [9] During vomiting, the propulsion of food up the esophagus and out the mouth comes from the contraction of the abdominal muscles; peristalsis does not reverse in the esophagus. [citation needed]
A catheter (thin tube) is inserted through the nose, and the patient is instructed to swallow several times. The probe measures muscle contractions in different parts of the esophagus during the act of swallowing. Manometry reveals failure of the LES to relax with swallowing and lack of functional peristalsis in the smooth muscle esophagus.
Pseudodiverticulae may also be seen on barium swallow imaging of the esophagus. The appearance is of flask-shaped pseudodiverticulae, which may be present in the entire esophagus diffusely, or may be segmental. The pseudodiverticulae may be seen preferentially in the lower esophagus on barium swallow also.
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 ...
