【摘要】：目的:探讨单极、双极电凝及超声刀对腹腔镜下全子宫切除术(TLH)中阴道残端组织的热损伤程度,指导妇科手术合理选择并使用电外科器械。方法:选取子宫内膜癌拟行腹腔镜下广泛性或改良广泛性子宫切除术的患者,收集分别以单、双极电凝及超声刀热凝的阴道残端组织各30块,显微镜下测量电凝部位热损伤宽度。结果:阴道残端组织热损伤宽度依次为:双极电凝[(4.1953±0.6805)mm]单极电凝[(3.1197±0.5825)mm]超声刀[(2.6460±0.6192)mm],差异有统计学意义(F=47.842,P=0.000)。三组两两比较差异有统计学意义(P=0.000)。结论:双极电凝对阴道残端组织的热损伤宽度最大,单极次之,超声刀最小,TLH术中环切阴道壁时要根据实际情况,合理选择电器械,避免副损伤。
[Abstract]:Objective: to investigate the thermal injury of vaginal stump tissue in laparoscopic hysterectomy with unipolar, bipolar electrocoagulation and ultrasonic knife. Methods: patients with endometrial carcinoma who were selected for laparoscopic or modified extensive hysterectomy were selected and collected separately. The vaginal stump tissue of bipolar electrocoagulation and ultrasonic knife thermocoagulation was 30 pieces each. Results: the width of thermal injury of vaginal stump tissue was measured under microscope. Results: the width of thermal injury of vaginal stump tissue was as follows: bipolar electrocoagulation [4.1953 卤0.6805)mm] unipolar electrocoagulation [3.1197 卤0.5825)mm] ultrasonic knife [2.6460 卤0.6192)mm], the difference was statistically significant. There were significant differences between the three groups. Conclusion: bipolar electrocoagulation has the largest thermal damage width in vaginal stump tissue. Second, the electric instruments should be reasonably selected according to the actual situation to avoid collateral injury in the minimization of TLH with ultrasonic knife.
