Abstract

ObjectiveThis study aimed to evaluate the feasibility and efficacy of in-office hysteroscopic ablation of submucous uterine fibroids using a diode laser.MethodA pilot study was conducted between January 2018 and January 2019 in a tertiary care university hospital. Patients with at least one symptomatic, class 0-2 FIGO classification, uterine fibroid <= 7 cm in size were eligible for inclusion. Evaluation of the changes in fibroid size and vascularity was performed using three-dimensional Doppler ultrasonography. Vaporization of the fibroid core was conducted using a 980-1470 nm wavelength diode laser inserted through the hysteroscope's working channel. The primary outcome was evaluation of the fibroid volume before and at 2 months after the procedure.ResultsTwenty women were enrolled in the study. At 2-month follow-up, the volume of the fibroids was significantly reduced (51.6 +/- 22.5 vs. 33.4 +/- 17.1 mm(3); p < 0.001). A major reduction of three-dimensional sonographic color Doppler vascularity (observed by the same operator and confirmed by four blind reviewers) was also achieved in 12/20 patients (60%; p = 0.03) while a reported symptom of heavy menstrual bleeding decreased from 18/20 (90%) to 2/18 (10%; p < 0.01).ConclusionHysteroscopic laser ablation represents a feasible and effective alternative for treating women with symptomatic submucous fibroids in the office setting. Further studies with larger sample size and longer follow-up periods are needed to validate this promising technique.Key messageThis pilot study shows that in-office hysteroscopic laser ablation (HLA) could be a feasible alternative to treat symptomatic submucous uterine fibroids by coagulating their core, reducing their size and vascularization.
