Visual examination of the esophagus?

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

Answer: (C)

The key idea is naming precision for examining a specific organ. Visual examination of the esophagus is done with an endoscope and is called esophagoscopy—the term literally combines “esophago-” (esophagus) with “-scopy” (viewing). This makes it the most specific choice for inspecting the esophagus.

Gastroscopy refers to looking at the upper GI tract with a focus that can include the esophagus and stomach, but it’s commonly associated with the stomach. Endoscopy is a general term for looking inside the body with an endoscope and doesn’t specify which organ. Esophagogastroduodenoscopy describes the combined examination of the esophagus, stomach, and duodenum, so it’s broader than just the esophagus. While it can include the esophagus, it isn’t as precise for a visual exam limited to that organ.

So, for a direct, specific visual examination of the esophagus, esophagoscopy is the best term.
