Abstract: Objective:Comparing the different effects between using electrotome and ultrasonic scalpel in segmentectomy for separating intersegmental plane.Methods:The ex vivo porcine lungs were chosen for experiments, the a segment of the cranial lobe of the right lung(RS1a) was removed by using electrotome(coagulation mode) or ultrasonic scalpel, the values of minimum air leak pressure among them were compared, and also the hematoxylin and eosin staining for evaluating the injury degree of incision edge.Results:The mean values of minimum air leak pressures for the intersegmental plane after segmentectomy were(17.3±1.0)cmH 2O by electrotome, (16.4±2.9) cmH 2O by ultrasonic scalpel, the differences did not reach significance between electrotome and ultrasonic scalpel( P=0.17). When focused on heat injury degree of incision edge, electrotome caused a heavier damage than ultrasonic scalpel[(819.70±158.00)μm vs.(354.35±98.81)μm, respectively, P<0.01]. Conclusion:Electrotome and ultrasonic scalpel presented different merits and defects, and we should opt energy devices rationally for separating inter-segmental plane.
