Uterine artery embolization versus myomectomy: a systematic review and meta-analysis

Abstract

Introduction: Uterine fibroids are the commonest benign tumors of the reproductive tract in women of childbearing age. They are usually asymptomatic but can cause menorrhagia. Treatments include myomectomy and uterine artery embolization (UAE). The latter is a relatively new procedure, therefore of special interest. Objectives: We conducted a systematic review and meta-analysis of all published studies to provide a comprehensive outlook on the effectiveness of UAE by comparing its outcomes to those of myomectomy. Electronic databases (PubMed and Cochrane Central) were systematically searched from January 2000 to March 2022 for published randomized control trials, observational studies, and meta-analyses that compared UAE to myomectomy for at least one of the pre-specified outcomes, namely re-intervention rates, length of hospital stay, and complications. Methods: We shortlisted nine studies for the final analysis. For continuous outcomes, results from random-effects meta-analysis were presented as mean differences (MDs) and corresponding 95% confidence intervals (CIs). Risk ratios (RRs) for dichotomous outcomes were pooled using a random-effects model. Results: The final analysis consisted of nine studies. Factors like re-intervention, hospitalization, and complications, each with its unique follow-up duration were assessed. Pooled analysis demonstrated significant results for greater re-intervention rates with UAE as compared to myomectomy (RR: 2.16, 95% CI: (1.27–3.66), p- value 0.004, heterogeneity I 2 = 85%). UAE holds a greater but statistically insignificant risk for major complications (RR: 0.62, 95% CI: (0.29–1.33), p- value 0.22, heterogeneity I 2 = 0%) and myomectomy shows a statistically insignificant greater risk for minor complications (RR: 1.72, 95% CI: (0.92–3.22), p- value 0.09, heterogeneity I 2 = 0%). UAE had a shorter but statistically insignificant duration of hospital stay (MD: −1.12, 95% CI: (−2.50 to 0.27), p- value 0.11, heterogeneity I 2 = 96%) ( p- value for subgroup differences = 0.005). Conclusion: Our meta-analysis of approximately 196,595 patients demonstrates that myomectomy results in a significant reduction in re-intervention rate compared to UAE.
