Active Locomotion of Magnetically Controlled Capsule Endoscopy in the Small Bowel: A Feasibility Study

Active Locomotion of Magnetically Controlled Capsule Endoscopy With Small Bowel Insufflation or Water Infusion: A Feasibility Study

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.

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.

Inclusion Criteria:

• Patients scheduled to undergo enteroscopy.

Exclusion Criteria:

• Patients with severe dysfunction of vital organs (e.g., heart, lungs). Patients with small bowel obstruction precluding adequate bowel preparation. Patients with a history of multiple abdominal surgeries. Patients with implanted devices such as cardiac pacemakers or metal implants. Patients with other high-risk conditions or lesions (e.g., moderate-to-severe esophagogastric varices, massive ascites).

Patients who are pregnant or lactating. Patients unable or unwilling to provide informed consent.
