【摘要】：目的探讨Liga Sure、超声刀及双极电凝对山羊肠系膜血管组织的热损伤程度及止血效果,指导腹腔镜手术中合理选择电外科器械。方法选取直径在1.03~5.44 mm之间的山羊肠系膜血管组织,分别用Liga Sure、超声刀及双极电凝行肠系膜血管凝断术各60次,切下180个血管组织标本显微镜下测量热损伤宽度;观察3种电器械单次凝断血管闭合成功率。结果肠系膜血管组织热损伤宽度双极电凝[(3.99±0.66)mm]Liga Sure[(3.30±0.71)mm]超声刀[(2.05±0.81)mm],差异有显著性(F=109.318,P=0.000,两两比较均P=0.000)。当血管直径≤3 mm时,Liga Sure[100%(32/32)]、超声刀[93.8%(30/32)]与双极电凝[68.8%(22/32)]相比单次闭合血管成功率均较高(P=0.001、0.010),Liga Sure和超声刀差异无显著性(P=0.492);当血管直径3 mm时,Liga Sure单次闭合血管成功率最高[100%(28/28)](与超声刀相比,P=0.010;与双极电凝相比,P=0.004),超声刀[75.0%(21/28)]与双极电凝[71.4%(20/28)]差异无显著性(P=0.763)。结论双极电凝对山羊肠系膜血管组织的热损伤宽度最大,Liga Sure次之,超声刀最小,临床上电凝血管时为减少副损伤可选用Liga Sure、超声刀。用Liga Sure闭合血管较双极、超声刀更为可靠,特别是直径3 mm的血管组织;超声刀闭合直径≤3 mm的血管较为安全。
[Abstract]:Objective to investigate the thermal injury degree and hemostatic effect of Liga Surel, ultrasonic knife and bipolar electrocoagulation on mesenteric vascular tissue in goats, and to guide the rational selection of electrosurgical instruments in laparoscopic surgery. Methods the mesenteric vascular tissues of goats with diameter between 1.03mm and 5.44mm were selected. The mesenteric vessels were coagulated with Liga Surel, ultrasonic knife and bipolar electrocoagulation for 60 times each, and 180 blood vessels were cut off to measure the width of thermal injury under microscope. To observe the success rate of blood vessel closure by single coagulation of three kinds of electrical instruments. Results the width of thermal injury in mesenteric blood vessels was bipolar electrocoagulation [(3.99 卤0.66) mm] Liga ure [(3.30 卤0.71) mm] ultrasonic knife [(2.05 卤0.81) mm], the difference was significant (FF109.318 P0. 000, P0.000). When the diameter of blood vessel 鈮，
