Oesophago-gastro-duodenoscopy (OGD)


If you experience symptoms such as upper abdominal discomfort, discharge of black-coloured stools, reflux of gastric acid, bloating, vomiting or chest pain, please take it seriously as it may be signs of stomach and esophageal cancers. As the symptoms at the early stage are not obvious, you should consult your doctor immediately if you notice any suspicious symptoms. The doctor will arrange an OGD according to the situation of the client, so as to accurately determine the health conditions of the esophagus, stomach and duodenum. In fact, esophagitis, esophageal ulcers, gastritis, gastric or duodenal ulcers, gastric polyps, and Helicobacter pylori infection can also be diagnosed by OGD.

OGD Procedure

OGD takes about 5 to 10 minutes to perform. Eating or drinking is prohibited for at least 6 hours before the examination. At first, local anaesthetic spray will be administered to the throat. During the procedure, the doctor will put a light-guide fibre tube with a micro lens in the front end through the mouth into the oesophagus, in order to examine the conditions of the esophagus, stomach and duodenum. If needed, biopsy removal will also be performed for further diagnosis. No eating or drinking in an hour after the examination. The DVD recording that records the process of the procedure will be provided to clients.

Reminders

  • Clients with cardiac pacemaker, diabetes, heart diseases, high blood pressure or any kinds of medication, especially anticoagulants or antiplatelet medicines, should inform the doctor in advance.
