【摘要】：目的探討Liga Sure、超聲刀及雙極電凝對山羊腸系膜血管組織的熱損傷程度及止血效果,指導(dǎo)腹腔鏡手術(shù)中合理選擇電外科器械。方法選取直徑在1.03~5.44 mm之間的山羊腸系膜血管組織,分別用Liga Sure、超聲刀及雙極電凝行腸系膜血管凝斷術(shù)各60次,切下180個血管組織標(biāo)本顯微鏡下測量熱損傷寬度;觀察3種電器械單次凝斷血管閉合成功率。結(jié)果腸系膜血管組織熱損傷寬度雙極電凝[(3.99±0.66)mm]Liga Sure[(3.30±0.71)mm]超聲刀[(2.05±0.81)mm],差異有顯著性(F=109.318,P=0.000,兩兩比較均P=0.000)。當(dāng)血管直徑≤3 mm時,Liga Sure[100%(32/32)]、超聲刀[93.8%(30/32)]與雙極電凝[68.8%(22/32)]相比單次閉合血管成功率均較高(P=0.001、0.010),Liga Sure和超聲刀差異無顯著性(P=0.492);當(dāng)血管直徑3 mm時,Liga Sure單次閉合血管成功率最高[100%(28/28)](與超聲刀相比,P=0.010;與雙極電凝相比,P=0.004),超聲刀[75.0%(21/28)]與雙極電凝[71.4%(20/28)]差異無顯著性(P=0.763)。結(jié)論雙極電凝對山羊腸系膜血管組織的熱損傷寬度最大,Liga Sure次之,超聲刀最小,臨床上電凝血管時為減少副損傷可選用Liga Sure、超聲刀。用Liga Sure閉合血管較雙極、超聲刀更為可靠,特別是直徑3 mm的血管組織;超聲刀閉合直徑≤3 mm的血管較為安全。
[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 鹵0.66) mm] Liga ure [(3.30 鹵0.71) mm] ultrasonic knife [(2.05 鹵0.81) mm], the difference was significant (FF109.318 P0. 000, P0.000). When the diameter of blood vessel 鈮，
