Gastroscopy is a study of the esophagus, stomach and beginning of the small intestine (duodenum). It is performed by the doctor using a flexible hose with camera through the mouth. Through a TV you get a clear picture of the parts examined and can also take tissue samples if needed. The examination takes just five minutes and is performed either with the patient awake or easily swayed.


The patient must be fasting at least 6 hours before the examination, i.e. Must not have eaten, drank, chewed chewing gum, snuffed or smoked. If the patient is to be examined with light sowing, do not drive a car afterwards.

Patients taking blood thinning medicines (eg Waran, Xarelto, Pradaxa) must notify us in good time before.

This is how the survey goes on

The patient is offered a local anesthetic in the pharynx which facilitates the first part of the examination. The local anesthetic can give a swelling feeling in the pharynx, but this is just a feeling and it gives no swelling or breathing effect.

The survey is performed on the left side. The patient can breathe normally throughout the examination, which takes about 5 minutes.

The study does not hurt but may be uncomfortable by some patients.

Patients who have chosen easy sowing get the sleeper through a blood vessel. The sewer is performed by anesthetist or anesthetist, and this monitors the patient throughout the sowing, which takes about 5 minutes, ie. You only sleep briefly during the investigation. The examination is performed in the same way if the patient is asleep or awake.

After the investigation

The investigator will tell you about the results. If tissue samples have been taken, these are sent for analysis and the analytical response goes directly to the inaugural doctor.

If you have been saddled, you can rest for a while in the attic room. Patients who have been injured can eat and drink when they feel stingy.

If the patient has chosen to use local anesthesia, do not eat or drink for half an hour after the examination.
