Endoscopy of the upper digestive tract

Upper digestive endoscopy, also known as gastroscopy, is a medical test that is used to visualize, diagnose and treat diseases of the upper part of the digestive tract (esophagus, stomach and duodenum), through a thin, flexible tube (endoscope) that It carries at its end a video camera whose image is transmitted to a monitor. Gastroscopy is usually performed under sedation, which reduces discomfort and allows the study to be well tolerated.
