Abstract
The use of mechanical tissue removal systems is more frequently implemented as the
first line approach for the treatment of intrauterine pathology. Scientific evidence
is provided that their use is easier and faster than the conventional resectoscope.
It is necessary to objectively evaluate the results on tissue removal systems for
the treatment of endometrial pathology as the reports in the literature are still
conflicting.
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.
To evaluate whether hysteroscopic morcellation or bipolar electrosurgical resection is more favorable for removing endometrial polyps in an office setting in terms of feasibility, speed, pain, and acceptability.
