Endoscopy

To check any abnormalities or disturbances in the esophagus and stomach, a doctor performs endoscopy. Endoscopy is a medical procedure in which the doctor inserts a flexible tube (endoscope) from the way of the mouth towards the esophagus and stomach. This endoscope has a camera attached to its bottom to give a clear image of the esophageal and stomach tissues.
