Capsule Endoscopes

Use CE for pre-examination of patients with AUGIB symptoms in emergency centers may reduce the need for emergency electronic gastroscopy and have certain advantages in clinical work. Patients with low-risk lesions can be discharged without the need for EGD and hospitalization, greatly improving the utilization of medical resources.

The investigators developed a wearable magnet tracking system, which provided a non-invasive and high accuracy method for capsule endoscopes localization. Data fusion from multiple sensors expanded positioning range and proposed localization algorithm overcame shortcomings of existing systems. This clinical trial was conducted to verify effectiveness and stability of the tracking system.
