Endoscopic polypectomy is now feasible for patients with cardiac pacemakers, even those with advanced devices. Careful precautions allow safe polyp removal without pacemaker complications.

Area of Science:

  • Gastroenterology
  • Cardiology
  • Medical Devices

Background:

  • High-frequency electrical devices, like those used in endoscopic polypectomy, were historically contraindicated in patients with cardiac pacemakers due to potential interference.
  • Advancements in pacemaker technology have introduced new considerations for managing patients requiring endoscopic procedures.

Purpose of the Study:

  • To evaluate the safety and feasibility of performing endoscopic polypectomy in patients with cardiac pacemakers.
  • To assess the risk of pacemaker dysfunction during and after endoscopic polypectomy procedures.

Main Methods:

  • Endoscopic polypectomy was performed on patients with implanted cardiac pacemakers.
  • Appropriate precautions were implemented during the procedures.
  • Pacemaker function was monitored before, during, and after the polypectomy.

Main Results:

  • A total of 11 polyps (10 colonic, 1 gastric) were successfully removed.
  • No instances of pacemaker malfunction or complications were observed.
  • Procedures were completed without adverse events related to pacemaker interaction.

Conclusions:

  • Endoscopic polypectomy can be safely performed in patients with cardiac pacemakers, including those with advanced devices, when appropriate precautions are taken.
  • Modern pacemakers appear to tolerate endoscopic polypectomy procedures, minimizing risks of dysfunction.
