Capsule Endoscopy
Conditions
Keywords
capsule endoscopy, small bowel disease, locomotion
Brief summary
The aim of this study is to evaluate the responsiveness of the capsule endoscope to the attitude controller and to investigate its active locomotion performance within the small bowel.
Detailed description
During the standard air insufflation or water infusion phases of double-balloon enteroscopy, researchers will use a handheld controller to try to steer the capsule. At the same time, the real-time imaging from both the enteroscope and the capsule will be simultaneously monitored to assess the capsule's active movement and its responsiveness to control.
Interventions
DEVICEmagnetic control
Intervention: On the day of the examination, the subject will swallow the capsule endoscope. This will be followed by a standard enteroscopy procedure. During the routine air/water insufflation phases of the enteroscopy, the researchers will attempt to guide the capsule's movement using an external magnetic control device.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| capsule endoscope's responsiveness to the attitude controller | During performing double-balloon enteroscope | Excellent: The magnetically controlled capsule endoscope can precisely follow the attitude controller to move to the target area. Moderate: The magnetically controlled capsule endoscope can follow the attitude controller's movement, but cannot be accurately guided to the target area. Poor: There are signs of magnetic attraction, but the capsule does not follow the movement of the attitude controller. |
