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 ...
Bougie over guidewire dilators are used at the time of gastroscopy or fluoroscopy. An endoscopy is usually performed first to evaluate the anatomy, and a guidewire is passed into the stomach past the obstruction. This may also be done fluoroscopically. Bougies are again introduced—this time over the guidewire—in sequentially increasing sizes.
Esophagitis can be diagnosed by upper endoscopy, biopsy, upper GI series (or barium swallow), and laboratory tests. [4] An upper endoscopy is a procedure to look at the esophagus by using an endoscope. While looking at the esophagus, the doctor is able to take a small biopsy. The biopsy can be used to confirm inflammation of the esophagus.
Esophagogastroduodenoscopy (EGD) or oesophagogastroduodenoscopy (OGD), also called by various other names, is a diagnostic endoscopic procedure that visualizes the upper part of the gastrointestinal tract down to the duodenum.
They are mainly observed in the Plummer–Vinson syndrome, [3] which is associated with chronic iron deficiency anemia.One in 10 patients with Plummer-Vinson syndrome will eventually develop squamous cell carcinoma of the esophagus, [4] but it is unclear if esophageal webs in and of themselves are a risk factor.
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.
Modified barium swallow – videofluoroscopic swallow (fluoroscopy). A lateral video X-ray that provides objective information on bolus transport, safest consistency of bolus, and possible head positioning and maneuvers that may facilitate swallow function depending on each individual's anatomy and physiology.
