Results
The polyps were completely removed, and no adverse events were observed in all 67 patients. The average operating time (8.3 min vs. 12.0 min, P = 0.014), insertion time (5.0 min vs. 9.0 min, P < 0.001), and number of insertions (1.0 vs. 8.2, P < 0.001) were significantly lower in the morcellation arm than in the electrosurgical resection arm.

Baseline Characteristics
Participant flow
Patients undergoing hysteroscopic resection of endometrial polyps were randomly allocated to undergo hysteroscopic morcellation or electrosurgical resection.
Adverse events
Outcome measures
The primary outcome was the operating time. Secondary outcomes were the removal success, fluid deficit, convenience with the technique, insertion time, number of insertions during the operation, visibility of the operative field, recurrence of the patient's chief complaint, and adverse events.
