Endoscopic ultrasound (EUS) or echo-endoscopy is a medical procedure in which endoscopy (insertion of a probe into a hollow organ) is combined with ultrasound to obtain images of the internal organs in the chest, abdomen and colon. It can be used to visualize the walls of these organs, or to look at adjacent structures.
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.
However, EGJOO has a variety of etiologies; evaluating the cause of obstruction with additional testing, such as upper endoscopy, computed tomography (CT imaging), or endoscopic ultrasound may be necessary. [2] When possible, treatment of EGJOO should be directed at the cause of obstruction.
An endoscopy is a procedure used in medicine to look inside the body. [1] The endoscopy procedure uses an endoscope to examine the interior of a hollow organ or cavity of the body. Unlike many other medical imaging techniques, endoscopes are inserted directly into the organ.
Therapeutic endoscopy is the medical term for an endoscopic procedure during which treatment is carried out via the endoscope. This contrasts with diagnostic endoscopy , where the aim of the procedure is purely to visualize a part of the gastrointestinal , respiratory or urinary tract in order to aid diagnosis .
Following upper endoscopy, the balloon is inserted into the esophagus and the balloon is distended with a fluid with known properties (e.g. conductivity and volume). [1] Each electrode then measures impedance, and a single pressure sensor at the end of the device measures pressure within the balloon. [1]
[2] Procedures performed within an endoscopy unit may include gastrointestinal endoscopy (such as gastroscopy, colonoscopy, ERCP, and endoscopic ultrasound), bronchoscopy, cystoscopy, or other more specialized procedures. Endoscopy units may be part of a hospital, where emergency procedures may be performed on ill patients admitted to hospital ...
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 ...
