摘要
目的:研究腹腔镜手术中单极电凝、双极电凝、等离子电切刀(PK刀)和结扎速血管闭合钳(LigaSure)对卵巢组织的热损伤效应,以助于临床合理选择电外科手术器械。方法:取手术中切除的人类正常卵巢组织,分别用上述电外科器械电凝,然后将组织块包埋、切片,HE染色后在光学显微镜下观察,并测量热损伤的宽度和深度。结果:电凝后卵巢组织均有不同程度的凝固性坏死,4种器械的热损伤坏死带范围宽度和深度之间比较,差异均有高度统计学意义(P=0.000)。其中两两比较中,LigaSure组的热损伤坏死深度小于单极电凝组(P=0.044),PK刀组的热损伤坏死宽度小于LigaSure组(P=0.002)、单极电凝组(P=0.024)和双极电凝组(P=0.045)。结论:各种腹腔镜电凝止血均会对卵巢组织造成一定的热损伤,在行腹腔镜卵巢手术时,应尽量减少电凝止血的操作,并尽量选用热损伤范围小的智能双极系统如PK刀等。
