摘要

Abstract

Background

At present

no commercially available endoscopic system is specifically designed for use in the battlefield

disaster relief

or unique environments with biosafety concerns. Therefore

this limitation stems from challenges such as limited portability

reliance on stable power

complex disinfection processes

and the risk of incomplete sterilization. To address these challenges

we developed a novel portable endoscopic system and evaluated its safety and effectiveness in both routine settings and specialized scenarios

including the global pandemic caused by a novel coronavirus

which represents an environment with biosafety concerns.

Methods

After sample size calculation

30 patients underwent esophagogastroduodenoscopy (EGD) or colonoscopy using the YunSendo (the experimental group) and Olympus systems (the control group) in a randomized order. Operation time

image quality

operational performance

lesion detection

and safety were assessed. Ten emergency patients with suspected upper gastrointestinal bleeding received bedside treatment using the YunSendo system during the global pandemic caused by a novel coronavirus. Clinical outcomes in emergency endoscopic treatment were assessed.

Results

No significant differences were observed between the YunSendo and Olympus groups in terms of image quality

lesion detection

and overall procedural performance. YunSendo facilitated biopsy and colonic polyp removal; no adverse endoscopy events were reported. YunSendo successfully executed diagnostic and therapeutic procedures in emergencies

with no observed mortality at 1

or 30 d

no rebleeding at 1 or 30 d

and no cross-infection rates.

Conclusions

The performance of the YunSendo portable endoscopic system was comparable to the Olympus system in terms of key metrics

demonstrating its utility in urgent scenarios. This novel system is particularly promising for medical rescue and military missions and for addressing battlefield and biosafety concerns.
