Background
2
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
2
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
2
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
7
or 30 d
no rebleeding at 1 or 30 d
and no cross-infection rates.
Conclusions
2
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.
