Utility of PKS Omni(®) electrosurgical device in laparoscopic hysterectomy

Abstract

Study Objective: The aim of this study is to evaluate the efficacy and safety of PKS Omni ® sealing device in laparoscopic hysterectomy. Design: Retrospective, non-randomized observational cohort. Setting: University hospital and academic affiliated private hospital. Patients: Patients with benign diseases undergoing multi-port laparoscopic hysterectomy between 2014 and 2015. Intervention: PKS Omni ® (Gyrus ACMI Inc..,USA) is bipolar electrosurgical device takes the energy from Plasmakinetic generator workstation G400, and this pulsed wave system involves two different modes; cutting (HC 1,2,3) and coagulation (VP1,2,3). We choosed VP3-power level 110 for coagulation and for cutting HC2-power level 50 according to tissue empedance. All the cases in this study were performed with a plasma kinetic energy system, and its electosurgical device PKS Omni ® The surgical operations were carried out by two surgeons who are experienced in gynecologic oncology and advance endoscopic surgery. Measurements and Main Results: Fifty-nine patients were evaluated, and all of the operations were completed by laparoscopy, but one is needed conversion to laparotomy because of severe adhesions between bowel and pelvic viscera. The median operating time was 100 minutes (60-185 min), and estimated blood loss was 20 ml (10-50 ml). Transfusion was not required. Recovery of gastrointestinal activity is occurred at post-operative 16 hour (12-24 houtr). Urinary catheter was not placed pre-or post operative, and spontaneous urinary activity started at 6 hour after operation (4-8 hour). Post-operative abdominal pain at rest was noted due to VAS (visual analog scale) score 0 to 10; 0 referring to no pain and 10 to unbearable pain. VAS score was 2 (0-6), and signified mild pain.

Conclusion PKS Omni is a novel, underused energy modality that promotes quick recovery and acceptable operation time with minimal blood loss and excellent post-operative pain scores.
