The clinical utility of a pulsed bipolar system and its electrosurgical device during total laparoscopic hysterectomy

Abstract

Objective: The aim of this research was to evaluate the efficacy and safety of the PlasmaKinetic (PK) PKS OMNI (R) (Gyrus ACMI, Maple Grove, MN) sealing device in laparoscopic hysterectomy. Materials and Methods: For this retrospective observational study, 60 patients who underwent multiport total laparoscopic hysterectomy between January 2014 and January 2015 in a tertiary-care university-based teaching hospital and an academically affiliated hospital were included in this study. The PKS OMNI is a bipolar electrosurgical device that takes energy from a PK generator workstation G400. This pulsed wave system has two different modes; cutting (High Cut 1,2,3) and coagulation (Vaporization 1,2,3). Results: Records of 60 patients were analyzed. The median age was 50 (range: ages 40-84), median body mass index was 26kg/m(2) (range: 22-32kg/m(2)), and median parity was 2 (range: 1-8). The median total operation time was 100 minutes (range: 70-240 minutes), estimated blood loss was 80mL (range: 30-250mL), and uterine weight was 207g (range: 50-900g). Degree of Surgical Difficulty and postoperative pain scores at rest were evaluated with a visual analogue scale system, from 0 to 10, and the medians of these scores were 5 (range: 3-7) and 4 (range: 2-6), respectively. The median recovery time of bowel movement was 16 hours (range: 8-26 hours), median spontaneous urination time was 7 hours (range: 4-29 hours), and median postoperative mobilization time was 8 hours (range: 6-10 hours). Conversion to laparotomy was needed in 1 patient due to severe pelvic adhesions. The median duration of hospital stay was 2 days (range: 2-4 days). Vaginal cuff dehiscence was detected in 1 (1.7%) patient who engaged in sexual intercourse on the 122nd day after surgery. Cuff cellulitis in 1 (1.7%) patient and unexplained fever in 1 (1.7%) patient were the other recorded complications. The median follow-up time was 12 months (range: 6-17 months). Conclusions: The PKS OMNI is a novel, underused energy modality that promotes quick recovery and acceptable operation time with minimal blood loss.
