Upper Gastrointestinal (GI) Endoscopy Appointment Information
Purpose of Examination
The purpose of this exam is to observe the esophagus, stomach, and duodenum, detect and diagnose abnormalities and diseases, and determine an appropriate treatment plan. A tube-shaped camera under 1 cm in diameter is inserted through the mouth to diagnose cancer, ulcers, inflammation (sores), polyps, and other conditions.
- Anesthesia is administered to the pharynx with a jelly or spray just before the examination.
- An endoscope is inserted through the mouth to observe and photograph the entire esophagus, stomach, and duodenum.
- If necessary, a dye is applied to clarify the irregularities of the mucosal surface. In addition, for early detection of esophageal cancer, the esophagus may be iodized for observation.
- A portion of the tissue may be collected (biopsied) to diagnose benign or malignant conditions.
- The exam is approximately 10 minutes but varies from person to person.
