In relational database theory, an equality-generating dependency (EGD) is a certain kind of constraint on data. It is a subclass of the class of embedded dependencies (ED). An algorithm known as the chase takes as input an instance that may or may not satisfy a set of EGDs (or, more generally, a set of EDs), and, if it terminates (which is a ...
The words esophagogastroduodenoscopy (EGD; American English) and oesophagogastroduodenoscopy (OGD; British English; see spelling differences) are pronounced / ɪ ˌ s ɒ f ə ɡ oʊ ˌ ɡ æ s t r oʊ ˌ d (j) uː oʊ d ɪ ˈ n ɒ s k ə p i /.
An endoclip is a metallic mechanical device used in endoscopy in order to close two mucosal surfaces without the need for surgery and suturing. Its function is similar to a suture in gross surgical applications, as it is used to join together two disjointed surfaces, but, can be applied through the channel of an endoscope under direct visualization
Esophageal inlet patches are diagnosed by upper endoscopy (esophagogastroduodenoscopy or EGD). Detection of esophageal inlet patches may be improved by the use of specialized imaging techniques such as narrow-band imaging (optical chromoendoscopy).
In relational database theory, an embedded dependency (ED) is a certain kind of constraint on a relational database.It is the most general type of constraint used in practice, including both tuple-generating dependencies and equality-generating dependencies.
FLIP is most often performed immediately following upper endoscopy (EGD). [1] EGD helps to rule out a mechanical obstruction as a cause for symptoms, and also provides an estimation on the distance from the incisors to the EGJ. [1] FLIP uses impedance planimetry to measure the cross sectional area of the esophageal lumen. [1]

Endoscopic foreign body retrieval refers to the removal of ingested objects from the esophagus, stomach and duodenum by endoscopic techniques. It does not involve surgery, but rather encompasses a variety of techniques employed through the gastroscope for grasping foreign bodies, manipulating them, and removing them while protecting the esophagus and trachea.
