Abstract

Background. As a vaporizing electrode has been successfully used to treat submucous myomas, we evaluated its safety and efficacy in performing endometrial ablation. Methods. Forty consecutive women with established menorrhagia with (n = 26) and without (n = 14) submucous myomas were enrolled in a prospective, noncomparative, pilot study. Hysteroscopic endometrial vaporization was performed with pure cutting current set at 200 watts. Results. All procedures were completed without complications. Median (interquartile range, IQR) fluid deficit was 90 (0-200) ml and median (IQR) operating time 10 (7-12.5) min. A significant correlation was observed between operating time and fluid absorption (Spearman's test by ranks, r = 0.47; p = 0.002). The degree of difficulty of the operation was classified as none on 28 (70%) occasions, mild on 11 (27.5%) and moderate on one (2.5%). After a mean ± s.d. follow-up of 20.3 ± 2.4 months, amenorrhea or spotting were reported by 23 (57.5%) subjects, hypomenorrhea by 10 (25%), normal flows by six (15%), and menorrhagia by one (2.5%). The median (IQR) menstrual score calculated according to a pictorial blood loss assessment chart dropped from 282.5 (199-383) to 0 (0-15) (p <0.0001). Six (15%) subjects were very satisfied with the effect of surgery, 30 (75%) satisfied, two (5%) uncertain, one (2.5%) dissatisfied and one (2.5%) very dissatisfied. Conclusions. The vaporizing electrode seems to combine the benefits of the cutting loop (speed, efficacy and possibility of removing myomas) and the roller-ball electrode (safety and limited fluid absorption) while avoiding their respective disadvantages, and may be considered an interesting alternative in the hysteroscopic treatment of menorrhagia.
