Early Esophagogastroduodenoscopy Performed Bedside Using Single-use Disposable Endoscope

We aim to evaluate whether the use of single-use gastroscopes at the bedside can reduce the time from clinical indication to procedure compared to reusable gastroscopes used in the endoscopy unit for patients referred for subacute gastroscopy. Participants in the first period will be scheduled for gastroscopy with a reusable gastroscope in the endoscopy unit, whereas participants during the second period will have a gastroscopy performed at the hospital department (bed-side) with a single-use gastroscope.
