An upper endoscopy is a short procedure performed under monitored anaesthetic care (MAC) or intravenous sedation (IVS) to investigate or diagnose upper gastrointestinal conditions including:
- Oesophageal cancer
- Stomach cancer
- Polyps
- Oesophageal gastrointestinal stromal tumour (GIST)
- Oesophagitis
- Peptic ulcers
- Varices
The procedure is performed using an endoscope to view the inside of the upper gastrointestinal tract and investigate abnormal tissue or polyps. An upper endoscopy, also known as oesophagogastroduodenoscopy (OGD), involves the insertion of a long, narrow flexible tube with a camera, which also includes a light, irrigation and insufflation systems, into the mouth through to the duodenum. Using different accessory instruments, an OGD can be used to both diagnose and treat a range of conditions through procedures such as biopsy (taking a tissue sample of abnormal polyps or suspicious lesions for further examination). The procedure can also be performed to remove foreign bodies, test for Helicobacter pylori, stop bleeding or relieve obstruction through stenting.
