A case series of urgent single-use gastroscopy in patients presenting with clinical signs of upper gastrointestinal bleeding

Aims Outbreaks of multi-drug resistant bacteria due to contaminated duodenoscopes and the Covid-19 pandemic have driven the development of single-use endoscopes. The first single-use gastroscope (Ambu aScope Gastro) received Conformité Européenne in April 2022 and is now available. Besides waste-disposal issues and the risk of infection, the diagnostic and therapeutic performance remains unclear. We aimed to evaluate single-use gastroscopes in patients with signs of upper gastrointestinal bleeding.
