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 ...
The air pulse sensory test was invented by Dr. Jonathan E. Aviv MD, FACS in 1993, [1] and has been used by otolaryngologists (ear, nose and throat doctors), [2] pulmonologists (lung doctors), [3] gastroenterologists (stomach and digestion doctors), [4] intensivists (intensive care specialists) [5] and speech-language pathologists who perform ...
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 ...
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.
The diagnostic test of choice is a barium swallow. [citation needed] Treatment. Esophageal webs and rings can be treated with endoscopic dilation. [citation needed]
Patients swallow urea labelled with an uncommon isotope, either radioactive carbon-14 (nowadays preferred in many countries) or non-radioactive carbon-13.In the subsequent 10–30 minutes, the detection of isotope-labelled carbon dioxide in exhaled breath indicates that the urea was split; this indicates that urease (the enzyme that H. pylori uses to metabolize urea to produce ammonia) is ...
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.
Radiographs (X-ray pictures) are taken while barium sulfate, a radiocontrast agent, fills the colon via an enema through the rectum. The term barium enema usually refers to a lower gastrointestinal series, although enteroclysis (an upper gastrointestinal series) is often called a small bowel barium enema.
