Early endoscopy for UGIB is associated with lower mortality compared with delayed endoscopy.2 Military personnel and residents in remote areas experience higher occurrences of gastrointestinal disorders and UGIB compared with urban citizens. The Army Command reported that gastrointestinal disorders accounted for 7–13% of medical evacuations.3 4 Conventional endoscopy (CE) poses challenges in specialised environments due to its large size, high water and power requirements and the labour-intensive processes of cleaning and disinfection. These factors hinder the timely management of gastrointestinal diseases in deployed settings.

    We previously developed a novel portable endoscope (PE), which is characterised by compact …
