Summary

Laparoscopic surgery heat risks were assessed. Bipolar and ultrasonic coagulation showed minimal thermal variation, making them safer near delicate structures compared to monopolar coagulation.

Area of Science:

  • Surgical Technology
  • Minimally Invasive Surgery
  • Thermal Dynamics in Medicine

Context:

  • Laparoscopic procedures require precise thermal management.
  • Heat generated by surgical instruments can pose risks to adjacent tissues.
  • Understanding thermal spread is crucial for patient safety during laparoscopy.

Purpose:

  • To quantify thermal variation from monopolar (MC), bipolar (BC), and ultrasonic coagulation (USC) during laparoscopy.
  • To evaluate the potential adverse effects of thermal spread on patients.
  • To compare the thermal profiles of different energy devices at varying power settings and distances.

Summary:

  • Temperature variations were measured using a thermal probe in 67 patients undergoing laparoscopic cholecystectomy.

  • Monopolar coagulation exhibited significant thermal spread (up to 29°C), while bipolar and ultrasonic coagulation showed minimal variations (3°C and 0.2°C, respectively) at 5 cm distance.
  • At higher power settings, monopolar coagulation still showed substantial heat variation (17°C), whereas bipolar and ultrasonic coagulation demonstrated negligible changes.

    • Impact:

    • Bipolar and ultrasonic coagulation are preferable for laparoscopic procedures near critical structures like the common bile duct and gastrointestinal tract due to minimal thermal spread.
    • This study informs the selection of energy devices to enhance patient safety and prevent iatrogenic injury during minimally invasive surgery.
    • Findings support the use of BC and USC to minimize thermal damage and improve surgical outcomes in laparoscopy.
