title: Comparison of the efficacy of the pulsed bipolar system and conventional electrosurgery in laparoscopic myomectomy - a retrospective matched control study.
abstract: OBJECTIVE
  Comparing the safety and effectiveness of the pulsed bipolar (PK) system and conventional electrosurgery in laparoscopic myomectomy (LM).
  
  
  METHODS
  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.
  
  
  RESULTS
  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.
  
  
  CONCLUSIONS
  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.
