A case-controlled study comparing harmonic versus electrosurgery in laparoscopic myomectomy

Outcomes of conventional and advanced energy devices in laparoscopic surgery: a systematic review

INTRODUCTION

Hemostasis is an important step in all surgical procedures. Mechanical methods of hemostasis have been gradually abandoned in favor of electrosurgery. The aim of this systematic review was to evaluate the effectiveness of electrosurgical instruments utilized in minimally invasive gynecological procedures.

MATERIAL AND METHODS

We performed a systematic review, including randomized controlled trials, prospective and retrospective studies, comparing the outcomes of different energy devices (EDs) used in laparoscopic gynecologic surgeries. We extracted data about blood loss (BL), mean operative time, post-operative pain, hospital stay and complications associated with each electrosurgical device.

RESULTS

We included 30 studies reporting comparative outcomes concerning conventional (bipolar and monopolar) and innovative EDs (Harmonic scalpel, LigaSure, Plasma kinetic gyrus, Thunderbeat, EnSeal, Marseal, Caiman and ALAN). New EDs were found to be more efficient in complex surgeries due to less intraoperative BL and shorter operative time. No significant decrease in hospital stay, post-operative pain or complications was found with the use of new energy instruments.

CONCLUSIONS

Although new electrosurgical devices seem an appealing and safer option, there is still insufficient evidence for one vessel-sealing technology to be considered superior to another. Therefore, monopolar and conventional bipolar (CB) are still widely used in laparoscopic gynecology.

"Energy devices in gynecological laparoscopy - Archaic to modern era"

The introduction of newer vessel sealing systems has revolutionized techniques of hemostasis during laparoscopic surgery. These devices allow for rapid sequential tissue and vessel sealing, coagulation, and transection. Despite of widespread use of newer advanced bipolar and ultrasonic devices, monopolar and conventional bipolar electro-surgery still carry weightage due to wider range of tissue effect, dissection capabilities, cost effectiveness, and ease of availability. Here in we discussed different types of commonly available energy sources in terms of mechanism, efficacy and safety as thorough knowledge is utmost important for surgeon to choose appropriate instrument for surgical procedure.
