Manually driven versus motor driven hysteroscopic tissue removal system for polypectomy: Long-term results

Area of Science:

• Gynecology
• Minimally Invasive Surgery
• Hysteroscopy

Background:

• Abnormal uterine bleeding (AUB) and endometrial polyps are common gynecological issues.
• Hysteroscopic tissue removal systems are used for polypectomy, but comparisons of manual and motor-driven systems are limited.
• Long-term clinical outcomes of these systems require further investigation.

Purpose of the Study:

• To compare the long-term clinical outcomes of a manually driven hysteroscopic tissue removal system (Resectr™ 9 Fr) versus a motor-driven system (Truclear™).
• To evaluate the recurrence and persistence of abnormal uterine bleeding and endometrial polyp recurrence after hysteroscopic polypectomy.

Main Methods:

• A follow-up of a multicenter randomized controlled trial involving 55 women with pathologically confirmed endometrial polyps.
• Prospective cohort study comparing manual versus motor-driven hysteroscopic tissue removal for polypectomy.
• Primary outcome: recurrence/persistence of AUB and time to recurrence. Secondary outcomes: polyp recurrence, symptom relief, and satisfaction scores.

Main Results:

• No statistically significant difference in the mean time to AUB recurrence or persistence between manual (26 months) and motor-driven (29 months) groups (P=.77).
• No significant differences observed in polyp recurrence (P=.22), symptom relief (P=.67), or patient satisfaction scores (P=.16 for symptoms, P=.61 for procedure).

Conclusions:

• Manual and motor-driven hysteroscopic tissue removal systems show comparable long-term efficacy for endometrial polyps.
• Neither system demonstrated a significant advantage in preventing AUB recurrence or improving patient satisfaction post-polypectomy.
