Not enough facilities to study

The primary objective is to investigate whether intake of approximately 200 ml of sugary fluid 2 hours before the scheduled gastroscopy of the abdomen can reduce the discomfort of fasting period for patients without reducing the quality of the study.

Current standard for fasting and fluid intake before gastroscopy is completely fasting 6 hours before the study. Studies in patients in general anesthesia has been found that it does not increase the risk of aspiration of stomach content during the operation by allowing the patient to drink up to 2 hours prior to anesthesia induction. There are no studies that have examined the quality gastroscopy using this fasting procedure. Some studies show that intake of sugary liquids do not have significant effect on gastric emptying.

There are not deemed to be ethical problems with this study, as it seeks to show that a more lenient standard procedure in endoscopy is as safe as the established. The study is considered safe.
