Hysteroscopic tissue removal system (MyoSure) for the resection of polyps, sub-mucosal leiomyomas and retained products of conception in an out-patient setting: A single UK institution experience.

ABSTRACT

PURPOSE: The present study aimed to elucidate the hysteroscopic tissue removal system (MyoSure) efficacy and safety amongst uterine cavity pathologies (UCPs), and to determine its feasibility in an outpatient setting. We also sought to identify possible factors that could adversely affect complete lesion excision. METHODS: 124 women underwent MyoSure procedure and 135 UCPs were excised, between January 2017 and January 2018. The MyoSure efficacy was evaluated, and potential factors correlated with increased incomplete excision rate were assessed, using both univariate and multivariate analysis. RESULTS: The overall MyoSure excision rate was 94.8%. 107/109 polyps and 14/19 leiomyomas were completely resected with a success rate of 98.1% and 73.7% respectively. The complete excision rate amongst retained products of conception (RPOC) cases was 100%. A significant correlation between leiomyomas and incomplete excision was found when compared to polyps and RPOC (p < 0.001). In this cohort, type II leiomyomas (OR = 1.8, p = 0.01) and maximal diameter > 4 cm (OR = 1.6, p = 0.02) were independently correlated with incomplete leiomyomas excision. Nine out of 124 women (7.3%) experienced severe pain during the procedure, while 17% and 73% reported moderate and mild pain respectively. Furthermore, 99% of women (123/124) would undergo the procedure again in the future or recommend it to a friend, for a similar pathology removal. CONCLUSIONS: MyoSure is an efficient, safe and feasible operative hysteroscopic procedure in an office-outpatient setting. It is associated with high patient acceptability and, it is highly recommended by the vast majority of the women. Large, and type II leiomyomas are seemingly procedure limitations.
