Removal of endometrial polyps:hysteroscopic morcellation versus bipolar resectoscopy, a randomized trial

Study Objectives: To compare hysteroscopic morcellation with bipolar resectoscopy for removal of endometrial polyps, in terms of procedure time, peri- and postoperative adverse events, tissue availability, and short-term effectiveness. Design: Multicenter, open label, randomized controlled trial (Canadian Task Force classification I). Setting: Day surgery setting of a teaching and a university hospital. Patients: Women with larger (≥1 cm) endometrial polyps. Interventions: Hysteroscopic morcellation with the TRUCLEAR 8.0 Tissue Removal System or bipolar resectoscopy with a rigid 8.5-mm bipolar resectoscope. Measurements and Main Results: Eighty-four women were included in the intention-to-treat analysis. Median operating time was 4.0 min (range: 2.5-7.1) and 6.0 min (range: 3.8-11.7) in the hysteroscopic morcellation and resectoscopy groups, respectively. Operating time was reduced by 38% (95% confidence interval: 5%-60%; p = .028) in the hysteroscopic morcellation group. Procedure time, which was defined as the sum of the installation and operating time, tended to be less for the hysteroscopic morcellation group (median 9.5 min [range: 7.6-12.2] vs 12.2 min [range: 8.8-16.0]; p = .072). Perforation occurred at dilation or hysteroscope (re)introduction in 3 patients of the resectoscopy group, resulting in procedure discontinuation or prolongation of hospital stay. Perforation occurred at dilation in 1 patient in the hysteroscopic morcellation group; however, the procedure was successfully completed. Postoperatively, 2 patients of the hysteroscopic morcellation group were diagnosed with a urinary tract infection. Tissue was available for pathology analysis in all patients, except for 2 patients in the resectoscopy group in whom the procedure was discontinued due to perforation. Conclusion: Hysteroscopic morcellation is a fast, effective, and safe alternative to bipolar resectoscopy for removal of endometrial polyps.
