What is the name of the visual examination of the esophagus, stomach, and duodenum?

The procedure known as esophagoscopy, also referred to as upper gastrointestinal endoscopy, is specifically designed to visually examine the esophagus, stomach, and duodenum. This procedure involves inserting a flexible tube with a camera (an endoscope) through the mouth and into the digestive tract, allowing healthcare providers to view these internal structures in real-time.

This examination plays a crucial role in diagnosing various conditions such as ulcers, tumors, inflammation, or other abnormalities in the upper gastrointestinal tract. By allowing for a direct visual assessment, esophagoscopy aids in guiding treatment decisions and interventions, making it a vital tool in the diagnostic process, especially for oncology patients who may have concerns related to cancer in these areas.

In contrast, a colonoscopy is used for examining the colon, which means it does not involve the upper gastrointestinal tract. Metastasis refers to the spread of cancer cells from one part of the body to another and does not pertain to a diagnostic procedure or examination. Reconstructive surgery involves surgical techniques to restore form and function but does not relate specifically to the visual examination of the GI tract.
