Gastroduodenoscopy is an examination of the mucous membrane of the esophagus, stomach, duodenum. A device called duodenoscope is used for this examination. During the procedure, a thin flexible tube of the device is inserted into the mouth, then lowered through the esophagus into the stomach and duodenum. The image is displayed on a monitor, allowing the doctor to make a successful and accurate diagnosis. The equipment allows you to take pictures and video recordings. This significantly increases the effectiveness of the procedure.

Use of a plastic mouth guard to prevent the teeth from grasping the apparatus.
