A Novel Portable Upper Gastrointestinal Endoscopy System Applied in Remote Populations: A Pilot Study

The application of conventional endoscopy in remote and outdoor areas lacking facilities remains challenges. Thus, the investigators developed a novel portable upper gastrointestinal endoscopy system that has the same functions as conventional endoscopy. A total of 24 participants from a medical unit on a remote island in China underwent endoscopy with the portable system between March and June 2021. The portable system packed into a suitcase is 68 × 42 × 32 cm in size, weighing less than 35 kg, and comprises a disposable sheathed system. The examination time and any malfunctions in the portable endoscopy system during the examination were recorded. After the examination was finished, the disposable sheathed system was removed, and a pressure leak test was performed to check the seal of the system. The patients were followed up within three days to confirm any adverse events such as nausea, vomiting, throat discomfort, bleeding, etc.
