Good Morning
Esophagogastroduodenoscopy (EGD) with biopsy, also known as upper endoscopy, is a procedure usually performed by a gastroenterologist (GI or intestinal doctor). This test involves passing an endoscope, a long, flexible black tube with a light and video camera on one end, through the mouth to examine the esophagus, stomach and the first part of the small intestine called the duodenum.
Hope this helps.
