Importance Uterine leiomyomas, also referred to as myomas or fibroids, are the most common benign tumors of the reproductive tract. Ulipristal acetate (UPA) is an active selective progesterone receptor modulator used as preoperative treatment for uterine myomas. Purpose The aim of this review is to provide an overview of the literature about the effects of UPA administration before hysteroscopic myomectomy. The clinical question in "PICO" format was in patients affected by uterine myomas undergoing operative hysteroscopic management, "Does UPA impact the surgical outcomes?" Evidence Acquisition We performed a systematic literature search in PubMed/MEDLINE and Embase for original studies written in English (registered in PROSPERO CRD42018092201), using the terms "hysteroscopy" AND "ulipristal acetate" published up to March 2019. Original articles about UPA treatment before hysteroscopic myomectomy (randomized, observational, retrospective studies) were considered eligible. Results Our literature search produced 32 records. After exclusions, 4 studies were considered eligible for analysis. Results show that UPA does not worsen the overall technical difficulty of hysteroscopic myomectomy. Moreover, it may increase the chance of complete primary myomectomy in complex hysteroscopic procedures. Conclusions and Relevance Despite the positive results presented in this systematic review, low-quality evidence exists yet on the impact of UPA treatment before hysteroscopic myomectomy. High-quality prospective randomized controlled trials are required to establish the impact of UPA on surgical outcomes of patients treated for uterine myomas by hysteroscopy. Moreover, long-term outcomes of myomectomies after UPA treatment (such as frequency of myoma recurrence, recovery time, and quality of life) should be determined. Target Audience Obstetricians and gynecologists, family physicians, nurse practitioners. Learning Objectives After completing this activity, the learner should be better able to (1) identify the main characteristics of uterine myomas; (2) discuss the advantages and disadvantages of the use of UPA before hysteroscopic myomectomy; and (3) select the most appropriate therapeutic strategy based on the characteristics of the myoma(s) and the patient.
BACKGROUND/AIMS: Ulipristal acetate ([UPA], Esmya®) is an orally active selective progesterone-receptor modulator that has been approved as preoperative treatment for uterine myomas. This systematic review aims to summarize the available data on surgical outcomes of patients undergoing myomectomy by hysteroscopy or by laparoscopy after preoperative treatment with UPA.
METHODS: this review was performed following PRISMA guidelines and was registered in PROSPERO (CRD42018092201). PubMed, EMBASE, and Medline databases were systematically searched electronically until March 2018 for keywords concerning this topic. There were included only peer-reviewed, English language journal articles.
RESULTS: two prospective studies and 4 retrospective studies were included. The effect of UPA on the endometrium does not increase the technical difficulty during hysteroscopic myomectomy, but it increases the chance of complete primary resection in complex hysteroscopic myomectomies. Moreover, UPA does not increase the overall technical difficulty of laparoscopic myomectomy. Contradictory results have been reported on the impact of UPA on the separation of the myoma from the myometrium and on the consistency of the myomas.
CONCLUSION: current results support the use of UPA prior to both surgical procedures. Further studies should confirm these preliminary findings and to assess the long-term outcomes of myomectomies following UPA treatment.
