Monopolar versus bipolar electrosurgery in hysteroscopic polypectomy

ABSTRACT

The aim of this study is to compare in random manner the intraoperative feasibility, effectiveness and safety of monopolar and bipolar electrosurgery in hysteroscopic polypectomy. 36 Symptomatic patients attending at outpatient clinics and diagnosed to have intrauterine polyps by HSG, transvaginal sonography or Diagnostic hysteroscopy were included. Patients were randomly assigned to two groups to have hysteroscopic polypectomy using either bipolar [Group A] or monopolar [Group B] electrosurgery under general anesthesia. Intraoperatively, the following parameters were noted and recorded time of start of anesthesia, time of introduction of the resectoscope, time of end of the procedures, time of recovery, amount of fluid used, amount of fluid Collected in the graduated suction, postoperative serum sodium was measured. Sociodemographic data for patients in both groups were comparable. The mean duration of operation was comparable in both group [14.76 +/- 2.95 minutes in bipolar group versus 14.79 +/- 2.94 minutes in monopolar group]. Fluid inflow, fluid outflow and fluid deficit were significantly higher in the monopolar group than in bipolar group. Bipolar electrosurgery seems effective, feasible and safe alternative to conventional monopolar system in hysteroscopic management of intrauterine pathologies
