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 ...
A barium swallow exam taken via fluoroscopy. Fluoroscopy can be used to examine the digestive system using a substance that is opaque to X-rays (usually barium sulfate or gastrografin), which is introduced into the digestive system either by swallowing or as an enema. This is normally as part of a double-contrast technique, using positive and ...
Oropharyngeal dysphagia; Other names: Transfer dysphagia: The digestive tract, with the esophagus marked in red: Specialty: Gastroenterology, ENT surgery: Symptoms: Hesitation or inability to initiate swallowing, food sticking in the throat, nasal regurgitation, difficulty swallowing solids, frequent repetitive swallows. frequent throat clearing, hoarse voice, cough, weight loss, and recurrent ...
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.
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 of the disease to medical or surgical treatment.
A Schatzki ring is usually diagnosed by esophagogastroduodenoscopy or barium swallow. Endoscopy usually shows a ring within the lumen of the esophagus which can be of variable size (see picture). The ring is usually located a few centimetres above the gastro-esophageal junction , where the esophagus joins the stomach.
The esophagus should be checked every year or two with a timed barium swallow because some may need pneumatic dilatations, a repeat myotomy, or even esophagectomy after many years. In addition, some physicians recommend pH testing and endoscopy to check for reflux damage, which may lead to a premalignant condition known as Barrett's esophagus ...
Barium sulfate, an insoluble white powder, is typically used for enhancing contrast in the GI tract. Depending on how it is to be administered the compound is mixed with water, thickeners, de-clumping agents, and flavourings to make the contrast agent. As the barium sulfate doesn't dissolve, this type of contrast agent is an opaque white mixture.
