The term "esophagogastroduodenoscopy" specifically refers to an endoscopic procedure that allows direct visualization of the esophagus, stomach, and duodenum - all parts of the upper GI tract. Esophagoscopy and gastroscopy also refer to endoscopic visualization of the upper GI tract, but are more specific to just the esophagus and stomach, respectively. Sigmoidoscopy refers to visualization of the sigmoid colon, which is part of the lower GI tract.
