• An upper GI endoscopy, or gastroscopy, is a test to visually assess the inside or 'mucosa' of your digestive system.

  • The esophagus, stomach and start of your small intestine is visualised.  The oropharynx is not completely assessed with this test, thus an ENT referral is something completed instead.

  • An upper GI endoscopy uses a long, thin, flexible tube with a tiny camera on the end with HD imaging used to visualise the mucosa.

  • There are 2 ways to do this test: (1) without sedation but a topical anesthetic is used, (2) with conscious sedation (NOT an anesthetic), meaning you are awake and aware but there is an amnestic quality to the medications used whereby you might not remember anything

  • An upper GI endoscopy can be helpful in finding health problems or figuring out the reason you are having certain symptoms, like trouble or pain when swallowing, pain in the stomach, or bleeding.

  • During an upper GI endoscopy, a biopsy (small piece of tissue to look at under the microscope) may be taken, but you will not feel this.

  • Sometimes, if certain problems are found during the test (like a bleeding ulcer or a foreign body ingested), tools can be passed through the tube to fix them.
