Endoscopy

Also known as OGD or gastroscopy

Oesophagogastroduodenoscopy (OGD) is a diagnostic endoscopic procedure that visualizes the upper part of the gastrointestinal tract up to the duodenum. The endoscope is a long, thin, flexible tube with a tiny video camera and light on the end. It is considered a minimally invasive procedure since it does not require an incision into one of the major body cavities and does not require any significant recovery after the procedure (unless sedation or anaesthesia has been used). It is used to diagnose and, in some cases, treat problems of the upper digestive tract.
