In upper gastrointestinal series examinations, the barium sulfate is mixed with water and swallowed orally, whereas in the lower gastrointestinal series (barium enema), the barium contrast agent is administered as an enema through a small tube inserted into the rectum. [2] Barium swallow X-ray examinations are used to study the pharynx [4] and ...
However, when present, symptoms may include difficulty swallowing , pain while swallowing (odynophagia), cough or globus sensation. [1] Whether esophageal inlet patches may cause other symptoms, such as chronic cough or laryngitis, is unclear. [1] Occasionally, esophageal inlet patches may be seen during a barium esophagram. [3]
Barium sulfate suspensions are provided by a radiologist or radiographer in advance of, or during a CT scan or fluoroscopic study to allow for better visualization of the gastrointestinal tract, such as in upper or lower gastrointestinal series. In upper gastrointestinal series, the patient is instructed to take nothing by mouth, which means to ...
a barium swallow may be performed before endoscopy to help identify abnormalities that might increase the risk of perforation at the time of endoscopy. If achalasia suspected an upper endoscopy is required to exclude a malignancy as a cause of the findings on barium swallow. Manometry is performed next to confirm.
The diagnosis of a hiatal hernia is typically made through an upper GI series, endoscopy, high resolution manometry, esophageal pH monitoring, and computed tomography (CT). Barium swallow as in upper GI series allows the size, location, stricture, stenosis of oesophagus to be seen. It can also evaluate the oesophageal movements.
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.
Although an occlusive tumor may be suspected on a barium swallow or barium meal, the diagnosis is best made with an examination using an endoscope. This involves the passing of a flexible tube with a light and camera down the esophagus and examining the wall, and is called an esophagogastroduodenoscopy .
String sign, or gastrointestinal string sign (also called string sign of Kantour), is a medical term for a radiographic finding on an upper GI series, in which the patient is given a radio-opaque material, such as barium, to drink. X-rays are then taken of the patient's stomach and intestines.
