The use of CO2 laser for inguinal hernia repair in elderly, pacemaker wearers.

Interference of electrical current with pacemaker activity is well known and has long been described. Almost every surgical procedure is now performed with the electrical knife, or electrocautery. In patients wearing a pacemaker this poses a problem, because of the danger of electronic interference within the pacemaker with consequent firing-frequency changes and the higher risk of intra- and postoperative bleeding and oozing when using a scalpel instead of cautery. We have performed 25 hernioplasties in elderly patients with permanent pacemakers using the CO2 laser technique. All operations were technically successful, and the immediate and long term (1 year) follow-up proved uneventful. Additionally normal pacemaker function was maintained during surgery and through the follow-up period. CO2 laser surgery is advantageous over electrocautery in patients with pacemakers because it does not interfere with pacemaker activity. Moreover, the laser produces normal hemostasis and does not stimulate muscle and nerve activity during surgery.
