title: Outpatient Hysteroscopic Polypectomy: Bipolar Energy System (Versapoint®) versus Mechanical Energy System (TRUCLEAR System®) - Preliminary Results.
abstract: OBJECTIVE
  The new hysteroscopic system with mechanical energy is an effective outpatient technique for diagnosis and treatment that has certain advantages over conventional hysteroscopy in the management of endometrial polyps.
  
  
  OBJECTIVE
  Our primary objective was to assess the total duration of hysteroscopy and polypectomy performed in an outpatient setting comparing the new mechanical energy hysteroscopy to the bipolar energy system. Our secondary objective was to compare the level of safety of both hysteroscopic techniques using the procedure success rate, the need for subsequent referral to surgery, existing complications, and comfort experienced by the patient during the procedure.
  
  
  METHODS
  This randomized controlled trial included the first 90 patients with an ultrasound diagnosis of endometrial polyp (>1 cm) who underwent an outpatient diagnostic and operative hysteroscopy at the Igualada Hospital (Barcelona) and agreed to be included in the study by signing an informed consent.
  
  
  RESULTS
  We obtained a 91% success rate with the TRUCLEAR System® compared to a 69% success rate with the Versapoint® system. Total operating time was 6.36 min in the TRUCLEAR System group versus 10.82 min in the Versapoint system group (p < 0.05), with a polypectomy time of 3.06 and 7.91 min, respectively (p < 0.05). There were no significant differences between the two techniques when analyzing pain using the visual analogue scale. No complications were recorded for either technique.
  
  
  CONCLUSIONS
  The mechanical energy system presents a significant decrease in the total duration of polypectomy and hysteroscopy when performed both by experienced staff and by staff in training, resulting in higher success rates without complications with respect to conventional hysteroscopy with bipolar energy.
