Comparing the safety and effectiveness of the pulsed bipolar (PK) system and conventional electrosurgery in laparoscopic myomectomy (LM).
Retrospective chart review of 194 women with symptomatic uterine fibroids undertaken LM was performed. Cases of LMs with PK cutting forceps were compared with a matched control group of standard LMs with conventional electrosurgery. Outcome measures for both groups were studied comparatively in terms of the length of operative time, amount of blood loss, requirement of blood transfusion and length of hospital stay.
The two groups were matched by age, body mass index, parity, previous cesarean delivery, size, number, and weight of fibroids. Amount of blood loss was significantly greater in electrosurgery group than in PK group at 243.8 ± 150.4mL versus 190.4 ± 178.5mL (p=0.025). Length of operation, hospitalization time, hemoglobin decrease, and requirement of blood transfusion were not significantly different.
Our findings indicate that PK system is more effective in LM when compared with conventional electrosurgery. PK system has advantage over conventional electrosurgery in less blood loss and may offer an alternative option for patients undergoing LM.
比较脉冲双极（PK）系统和传统电外科在腹腔镜子宫肌瘤剔除术（LM）中的安全性和有效性。
对 194 例因有症状的子宫肌瘤而行 LM 的妇女进行回顾性图表分析。用 PK 切割钳进行 LM 的病例与采用传统电外科的标准 LM 进行匹配对照。对两组的手术时间、出血量、输血需求和住院时间等指标进行比较。
两组在年龄、体重指数、产次、剖宫产史、肌瘤大小、数量和重量方面相匹配。电外科组的出血量明显多于 PK 组，分别为 243.8±150.4ml 和 190.4±178.5ml（p=0.025）。手术时间、住院时间、血红蛋白下降和输血需求无显著差异。
与传统电外科相比，PK 系统在 LM 中更有效。PK 系统在出血量较少方面优于传统电外科，可为行 LM 的患者提供另一种选择。
