Which procedure allows direct visualization of the upper GI tract?

• A. EGD (Esophagogastroduodenoscopy)
• B. Sigmoidoscopy
• C. Colonoscopy
• D. Laryngoscopy

Answer: (A)

Direct viewing of the upper GI tract is accomplished with esophagogastroduodenoscopy, or EGD. This procedure uses a flexible endoscope passed through the mouth to directly inspect the mucosa of the esophagus, stomach, and the first part of the duodenum—the components of the upper GI tract. It often allows biopsies or therapeutic interventions during the same session. Sigmoidoscopy examines the distal portion of the colon and rectum, while colonoscopy views the entire colon, and laryngoscopy looks at the larynx and upper airway rather than the GI tract.
