Which part of the gastrointestinal tract does a gastroscope primarily examine?

• A. The colon and rectum
• B. The esophagus, stomach, and duodenum
• C. The small intestine
• D. The pancreas and liver

Answer: (B)

A gastroscope is specifically designed for examining the upper gastrointestinal tract, which includes the esophagus, stomach, and the duodenum. This scope allows for direct visualization of these areas, facilitating the diagnosis and potential treatment of various conditions such as ulcers, inflammation, and tumors. The gastroscope's functionality includes taking biopsies and performing therapeutic interventions, which are crucial for managing upper GI disorders. By contrast, options such as the colon and rectum, small intestine, or pancreas and liver represent areas that do not fall under the purview of the gastroscope’s examination capabilities. The lower gastrointestinal tract, including the colon and rectum, is typically assessed using a colonoscope. The small intestine may require different types of endoscopes or specific procedures for thorough examination. The pancreas and liver, while related to digestive health, do not involve direct endoscopic intervention via a gastroscope; instead, imaging techniques or endoscopic ultrasound are usually employed for those organs. Hence, the primary focus of a gastroscope is rightly on the upper GI tract: the esophagus, stomach, and duodenum.
