Objective: The efficacy of an alternative thermocautery shears (ATS) constructed by the investigators was assessed in a porcine model against an electrosurgical unit (ESU) and Harmonic scalpel (HS) Methods: Forty-five mesenteric arteries were divided using the respective apparatus. Time from application to transection and hemostasis was recorded. Thirty 1 centimeter segments of femoral artery were sealed by the test apparatus and bursting pressures obtained. The welded mesenteric vessels were evaluated for wall damage Results: No statistical difference between the HS and the ATS for time of vessel transection and hemostasis was noted. The bipolar ESU has the longest time (p0.001). Bursting pressures were comparable between the HS and the ATS (p Conclusion: This study showed that the ATS may be a viable alternative to current modalities of hemostasis.
