Two systematic reviews evaluated the efficacy of EA in women with abnormal uterine bleeding. One compared EA with the LNG-IUD and reported on safety and efficacy, while the other compared EA with hysterectomy and reported on quality of life.
Bergeron and colleagues reviewed 13 studies that included 884 women to compare the efficacy and safety of EA or resection with the LNG-IUD for the treatment of premenopausal women with AUB.3 They found no significant differences between EA and the LNG-IUD in terms of subsequent hysterectomy (risk ratio [RR] = 1.3; 95% confidence interval [CI], 0.60-2.11). It was not surprising that, when looking at age, EA was associated with a higher risk for hysterectomy in women younger than age 42 (RR = 5.26; 95% CI, 1.21-22.91). Conversely, subsequent hysterectomy was less likely with EA compared to LNG-IUD use in women older than 42 years. However, statistical significance was not reached in the older group (RR = 0.51; 95% CI, 0.21-1.24).
In the systematic review by Vitale and colleagues, 9 studies met inclusion criteria for a comparison of EA and hysterectomy, with the objective of ascertaining improvement in quality of life and several other measures.4
Although there was significant heterogeneity between assessment tools, both treatment groups experienced similar improvements in quality of life during the first year. However, hysterectomy was more advantageous in terms of improving uterine bleeding and satisfaction in the long term when compared with EA.4
WHAT THIS EVIDENCE MEANS FOR PRACTICE
As EA is considered, it is important to continue to counsel about the efficacy of the LNG-IUD, as well as its decreased associated morbidity. Additionally, EA is particularly less effective in younger women.
