Which term describes a visual examination of the stomach using an endoscope?

• A. Gastroscopy
• B. Endoscopy
• C. Esophagoscopy
• D. Esophagogastroduodenoscopy

Answer: (A)

Gastroscopy is the term for visual inspection of the stomach with an endoscope. The gastroscope is a scope designed specifically for examining the stomach lining, allowing the clinician to look for inflammation, ulcers, tumors, or other abnormalities and to take biopsies if needed.

Endoscopy is a general word for looking inside hollow organs with an endoscope, so it could refer to any part of the GI tract, not just the stomach. Esophagoscopy targets the esophagus. Esophagogastroduodenoscopy (EGD) describes examining the esophagus, stomach, and duodenum together. Because the question is asking for the stomach-focused examination, gastroscopy is the most precise choice.
