A Novel Portable Upper Gastrointestinal Endoscopy System

January 13, 2022 updated by: Zhuan Liao, Changhai Hospital

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.

Detailed Description

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.

Intervention / Treatment
Experimental: a novel portable upper gastrointestinal endoscopy system
Device: a novel portable upper gastrointestinal endoscopy system
Patients arrived at the hospital in the morning after an overnight fast (>6 hours). The patients took oral dyclonine glue 15 mins before their examination. The doctors prepared the portable endoscopy system so that it was in working status and the disposable sheathed system was placed on the endoscope optical probe.
