Final answer:
Gastroscopy is achieved by inserting the gastroscope through the esophagus. An endoscope is used to illuminate and transmit images for diagnosis or interventions such as biopsies and the removal of polyps.
Step-by-step explanation:
Gastroscopy is accomplished by inserting the gastroscope through the esophagus. The esophagus provides the necessary passageway from the pharynx to the stomach, allowing the gastroscope to reach the stomach without any incisions.
This non-invasive procedure enables healthcare professionals to diagnose issues within the upper GI tract, such as peptic ulcers, by using a device called an endoscope, which transmits light and images back to the observer via fiber optic technology. Moreover, the endoscope can facilitate the collection of biopsy samples or the removal of polyps with surgical instruments attached to it.
The gastroscope is inserted through the esophagus during a gastroscopy. The esophagus is a muscular tube that connects the pharynx to the stomach.
It allows food to be pushed from the pharynx to the stomach. In a gastroscopy, a tube with a tiny camera, called an endoscope, is inserted through the esophagus and visualizes the upper gastrointestinal tract to diagnose conditions such as peptic ulcers.
