Endometrial ablation using hysteroscopic instillation of hot saline solution into the uterus

Objective: To evaluate the clinical effectiveness and safety of endometrial ablation by hysteroscopic instillation of hot saline using the Hydro-Therm-Ablator ® (HTA) system. Methods: A total of 14 patients with menorrhagia, underwent the HTA procedure under general anethesia. Follow up of 9–18 months is reported. Three patients had undergone tubal ligation years before the procedure and one underwent it immediately after HTA at the same session. Results: One procedure was cancelled due to technical problems, and roller-ball ablation was performed. There were no procedure related complications. A total of 11 patients reported significant reduction in bleeding, or amenorrhea, 9–18 months after the HTA procedure. One patient, although eumenorrheic after the ablation, considered the procedure a failure and requested hysterectomy. One patient with menorrhagia 3 months after the procedure, had a second HTA ablation and is now amenorrheic. Conclusions: This series of patients who underwent HTA ablation had successful reduction of menorrhagia to oligomenorrhea or amenorrhea.
