Abstract

The purpose of this randomized controlled study was to compare conventional resectoscopy and hysteroscopic morcellation among residents in training (Canadian Task Force classification I). Sixty women with an intrauterine polyp or myoma were randomized to either hysteroscopic removal by conventional resectoscopy or hysteroscopic morcellation performed by 6 residents in training for obstetrics and gynecology (10 procedures per resident). The mean operating time for resectosocpy and morcellation was 17.0 (95% confidence interval [95% CI] 14.1-17.9, standard deviation [SD] 8.4) and 10.6 (95% CI 7.3-14.0, SD 9.5) min, respectively (p = .008). Multiple linear regression analysis showed that operating time increased significantly, for both resectoscopy and morcellator, when volume of intrauterine disorder increased. The use of the hysteroscopic morcellator reduced operating time more than 8 min in comparison to conventional resectoscopy (p < .001) when correction for volume was applied. Subjective surgeon and trainer scores for convenience of technique on a visual analog scale were in favor of the morcellator. No learning curve was observed. In conclusion, the hysteroscopic morcellator for removal of intrauterine polyps and myomas offers a good alternative to conventional resectoscopy for residents in training.
