The patients answered a questionnaire clarifying their previous experience of gastroscopy, and if relevant, the discomfort of previous examination and their anxiety for the actual examination on a visual analogue scale (VAS scale). A post endoscopy questionnaire evaluated discomfort during the examination in general, during introduction of the endoscope and for the rest of the examination (VAS scale). The following parameters were assessed by answering yes or no; gagging, choking, pain from the nose, throat and the stomach. The patients stated whether the degree of discomfort had been greater, lesser or as expected compared to previous endoscopy and whether they in a future gastroscopy would prefer sedation, and finally they stated their preference for a future procedure (OG/TG).
