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.
