  • The gastroscope is inserted in through the mouth, down the esophagus and further down to the stomach and duodenum. How far the scope is inserted depends on which organs are inspected or which organ is suspect of tumor growth.
  • Air is blown in to clear the esophagus/stomach and get a better view during insertion of the scope.
  • The mucosa is inspected for abnormalities.
  • Perform necessary procedure.

The examination usually lasts around 10-30 minutes.
