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 ...
Endoscopic ultrasonography is most commonly used in the upper digestive tract and in the respiratory system. The procedure is performed by gastroenterologists or pulmonologists who have had extensive training. For the patient, the procedure feels almost identical to the endoscopic procedure without the ultrasound part, unless ultrasound-guided ...
A gastrointestinal series, also called a GI series, is a radiologic examination of the upper and/or lower gastrointestinal tract. Upper GI series Lower GI series
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.
Upper gastrointestinal bleeding affects around 50 to 150 people per 100,000 a year. It represents over 50% of cases of gastrointestinal bleeding. [ 2 ] A 1995 UK study found an estimated mortality risk of 11% in those admitted to hospital for gastrointestinal bleeding.
evaluate bowel wall features of both upper and lower gastro-intestinal tract Magnetic resonance enterography is a magnetic resonance imaging technique used to evaluate bowel wall features of both upper and lower gastro-intestinal tract , although it is usually used for small bowel evaluation. [ 1 ]
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.
Early development of impedance planimetry for evaluating the gastrointestinal tract began in the 1980s. [6] FLIP was first developed with a short balloon catheter, which measures distension across the esophagogastric junction. [7] A second generation device was later released, which measures secondary peristalsis proximal to the EGJ. [7]
