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 /. It is also called panendoscopy (PES) and upper GI endoscopy.
Barium X-ray examinations are useful tools for the study of appearance and function of the parts of the gastrointestinal tract. They are used to diagnose and monitor esophageal reflux, dysphagia, hiatus hernia, strictures, diverticula, pyloric stenosis, gastritis, enteritis, volvulus, varices, ulcers, tumors, and gastrointestinal dysmotility, as well as to detect foreign bodies.
Upper endoscopy is used to evaluate for mechanical causes of obstruction. [2] Endoscopic findings may include a hiatal hernia, esophagitis, strictures, tumors, or masses. [2] Increased pressure at the LES over time may result in an epiphrenic diverticulum. [2]
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).
Commonly patients are found to have esophagitis and may have an esophageal stricture. Biopsies are usually done to look for evidence of esophagitis even if the EGD is normal. Usually no further testing is required if the diagnosis is established on EGD. Repeat endoscopy may be needed for follow up. If there is a suspicion of a proximal lesion ...
An endoscopy can examine the esophagus, stomach and part of the small intestines, and CT scans may be used to check for tumors or structural abnormalities in the head, neck or chest.
An endoscopy is usually performed first to evaluate the anatomy, and a guidewire is passed into the stomach past the obstruction. This may also be done fluoroscopically. Bougies are again introduced—this time over the guidewire—in sequentially increasing sizes.
Tiny plastic particles have been found throughout the human body, but researchers say they’re just starting to understand the impact. When Jaime Ross, PhD, a neuroscientist and assistant ...
