Oesophagogastroduodenoscopy (OGD)
OGD is the technique that allows the direct visualization of the upper gastrointestinal tract. This procedure involves passing an endoscope with a diameter of 1cm via the mouth into the oesophagus, stomach and duodenum. The endoscope is a flexible tube attached to an optical system to examine for diseases, such as inflammation, tumors or polyps etc. Additional therapeutic procedures can also be performed at the same time, such as endoscopic polypectomy, control of upper gastrointestinal tract bleeding and tumor biopsy.
