Findings from one study which randomized patients with RPOC to hysteroscopic morcellation versus hysteroscopic resection were as follows: whilst both approaches were safe with high rates of complete tissue removal, hysteroscopic morcellation was significantly faster than loop resection
. Additionally, procedure time and number of scope reinsertions were also significantly lower in the morcellation group .

Tissues were taken by bipolar loop resection
and left nephrostomy was inserted.
Techniques used for mucosal resection after submucosal injection were loop resection
, cap-assisted resection, and band ligator-assisted resection [10-13, 18].
In a retrospective analysis, the TRUCLEAR morcellator reduced operative time by about two thirds for polyps and one half for Type 0 and Type I myomas, compared with monopolar loop resection
. (15) A later study of inexperienced ObGyn residents demonstrated shorter operative times and lower total fluid deficits for the TRUCLEAR morcellator, compared with resectoscopic procedures overall, during polypectomy and myomectomy of Type 0 and Type I myomas.

Patients with fibroids who were randomized to rollerball ablation also underwent electrocautery loop resection
of the fibroid, but the electrocautery was not used to remove the endometrium in general.
