What is the main purpose of using a fiber optic scope during an EGD?

The primary purpose of using a fiber optic scope during an esophagogastroduodenoscopy (EGD) is to visualize internal organs. This procedure allows healthcare providers to examine the upper gastrointestinal tract, including the esophagus, stomach, and duodenum, in a detailed manner. The fiber optic technology provides clear images of these structures, aiding in the diagnosis and assessment of various conditions such as ulcers, inflammation, or tumors.

Visualizing internal organs using this technology is critical in guiding clinicians in making informed decisions about further treatment or interventions. By providing direct visualization, the fiber optic scope enables essential evaluations that cannot be achieved with non-invasive imaging methods alone. Other methods listed, such as gathering blood samples, measuring blood pressure, or administering cuts, are either unrelated to the procedure or do not accurately reflect the key function of the fiber optic scope within the context of an EGD.
