Energy sources incorporating "vessel sealing" capabilities are being increasingly used in gynecologic laparoscopic surgery although conventional monopolar and bipolar electrosurgery remain popular. The preference for one device over another is based on a combination of factors, including the surgeon's subjective experience, availability, and cost. Although comparative clinical studies and meta-analyses of laparoscopic energy sources have reported small but statistically significant differences in volumes of blood loss, the clinical significance of such small volumes is questionable. The overall usefulness of the various energy sources available will depend on a number of factors including vessel burst pressure and seal time, lateral thermal spread, and smoke production. Animal studies and laboratory-based trials are useful in providing a controlled environment to investigate such parameters. At present, there is insufficient evidence to support the use of one energy source over another.
能源结合“血管密封”功能，越来越多地被应用于妇科腹腔镜手术，尽管传统的单极和双极电外科仍然很受欢迎。对一种设备的偏好取决于多种因素的结合，包括外科医生的主观经验、可用性和成本。虽然腹腔镜能源的比较临床研究和荟萃分析报告了出血量的微小但统计学上显著的差异，但如此小体积的临床意义是值得怀疑的。各种可用能源的总体有用性将取决于许多因素，包括血管爆裂压力和密封时间、横向热扩散和烟雾产生。动物研究和基于实验室的试验在提供一个受控的环境来研究这些参数方面是有用的。目前，没有足够的证据支持使用一种能源而不是另一种能源。
