%X Objectives: Quantum Energy Surgical Device (QESD) is a recent thermal working surgical device which works with the principle of tissue application of highly quantum-energized argon gas atoms that are transformed into plasma by employing kinetic energy. In this study, we aimed to examine the operation periods, hemostasis and histological changes on the cutting surface, and the free radicals that can be formed during this period in the partial hepatectomies performed with QESD and bipolar electrocautery (BEC).Patients and Methods: Partial hepatectomies were performed with BEC and with QESD on 10 rabbits each. Obtained materials during the operation (acute-term group) and 7 days after the operation (short-term group) were prepared for light microscopy, electron microscopy and measurements of free radicals.Results: In the operations with QESD, hemorrhage was found to be much less and the operation procedures were determined to be accomplished in a much shorter time in comparison with BEC. In the histopathological examinations, while various changes were determined on the cutting surfaces of both groups with regard to thermal trauma, the superiority of QESD drew attention regarding hemostasis activities, damage formed and amelioration periods. Free radicals were determined to be formed less in QESD operations.Conclusion: The conclusions indicate that QESD method is superior to BEC method with respect to total operation period, hemostasis efficiency and wound amelioration. It is revealed that the free radicals are within acceptable levels in both devices.
