Outpatient hysteroscopic polypectomy: bipolar energy system (Versapoint®) versus diode laser – randomized clinical trial

OBJECTIVE: To compare the resection of endometrial polyps with two different devices: the Versapoint biopolar electrode and the Diode Laser. METHODS: One hundred and two patients diagnosed with endometrial polyps were randomly assigned to undergo hysteroscopic polypectomy: one group (n = 52) performed with Versapoint bipolar electrode through a 5Fr working channel and the other group with Biolitec Diode Laser (n = 50) using a specific fiber for polyps in a 7Fr working channel. All cases were managed on an outpatient basis, without anesthesia and using a rigid 30(o) hysteroscope and saline solution as a distention medium. MAIN OUTCOME MEASURES: Complete resection rate, operative time, complications, intraoperative pain and relapse rate after three months. RESULTS: Intraoperative pain and polyp resection time was similar in both groups. Upon second look hysteroscopy at 3-month, a higher percentage of women of the Versapoint group presented polyp relapse (32.6 versus 2.2%, p = 0.001). Elimination of the polyp after incomplete resection was higher in the Laser group. A significantly higher number of patients in the Laser group considered the procedure to be highly recommendable (p = 0.02). CONCLUSION: Polypectomy with Diode Laser resulted in fewer relapses and a higher procedure satisfaction rate as compared to Versapoint.
