Wireless capsule endoscopy is safe for patients with cardiac pacemakers (PM) in VOO mode. However, image loss occurred when the capsule neared the abdominal PM, indicating potential interference.

Area of Science:

  • Gastroenterology
  • Biomedical Engineering
  • Medical Devices

Background:

  • Wireless capsule endoscopy aids in diagnosing occult gastrointestinal bleeding.
  • Cardiac pacemakers (PM) are a contraindication due to potential electromagnetic interference.
  • No documented interference cases between capsule endoscopy and PMs exist.

Observation:

  • A patient with an abdominal wall-implanted PM underwent capsule endoscopy.
  • Cardiac monitoring showed no alteration in PM function (VOO, unipolar mode).
  • Capsule recording revealed over 3 hours of lost video signal.

Findings:

  • Wireless capsule endoscopy is safe for patients with PMs in VOO mode.
  • Significant signal interference was observed when the capsule was in proximity to the PM.

  • The interference impacted the quality and completeness of the recorded images.

    • Implications:

    • Capsule endoscopy can be considered for patients with PMs in VOO mode.
    • Careful patient selection and monitoring are crucial due to potential interference.
    • Further research is needed to understand and mitigate interference between capsule endoscopy and implanted cardiac devices.
