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 ...
Before FEESST was invented, all tests of swallowing, be they X-ray based tests (Modified Barium Swallow (MBS) [8] or endoscopy-based tests (Fiberoptic Endoscopic Evaluation of Swallowing (FEES) [9] [10] solely looked at the motor component of swallowing without examining the sensory aspect of a swallow or the ability to feel.
The esophagus above the narrowing is often dilated (enlarged) to varying degrees as the esophagus is gradually stretched over time. [9] An air-fluid margin is often seen over the barium column due to the lack of peristalsis. A five-minutes timed barium swallow can provide a useful benchmark to measure the effectiveness of treatment. [citation ...
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 ...
Medical genetics. A Schatzki ring or Schatzki–Gary ring is a narrowing of the lower esophagus that can cause difficulty swallowing (dysphagia). The narrowing is caused by a ring of mucosal tissue (which lines the esophagus) or muscular tissue. [1] A Schatzki ring is a specific type of "esophageal ring", and Schatzki rings are further ...
Formula. BaO4S. Molar mass. 233.38 g·mol −1. Barium sulfate suspension, often simply called barium, is a contrast agent used during X-rays. [1] Specifically it is used to improve visualization of the gastrointestinal tract (esophagus, stomach, intestines) on plain X-ray or computed tomography. [2] It is taken by mouth or used rectally.
Heller myotomy is a surgical procedure [1] in which the muscles of the cardia (lower esophageal sphincter or LES) are cut, allowing food and liquids to pass to the stomach.It is used to treat achalasia, a disorder in which the lower esophageal sphincter fails to relax properly, making it difficult for food and liquids to reach the stomach.
Nutcracker esophagus is characterized as a motility disorder of the esophagus, meaning that it is caused by abnormal movement, or peristalsis of the esophagus. [2] People with motility disorders present with two main symptoms: chest pain or difficulty with swallowing. Chest pain is the more common. The chest pain is very severe and intense, and ...
