Long-term outcome of endometrial ablation therapy with Cavaterm Thermal Balloon in patients with abnormal uterine bleeding

ABSTRACT

Objective: The purpose of this study was to evaluate the long-term outcome of endometrial ablation (EA) therapy with Cavaterm Thermal Balloon in patients with abnormal uterine bleeding (AUB). Material and Methods: The retrospective cross-sectional study was performed on 209 patients who referred to Shahid Sadoughi Hospital in Yazd, Iran between March 2010 and September 2017 with AUB undergoing EA therapy. The data was collected by a questionnaire from the medical records of patients and phone call. The primary and secondary outcomes post EA therapy (from six months to seven years post-operatively) were assessed in patients. Results: The mean age of participants was 45.9±5.9 years and the mean follow-up duration was 21.2±13.2 months. The rate of treatment response was 95% in the first six months and 92.1% thereafter. The prevalence of amenorrhea was 41.2%. The patient satisfaction rate at the end of follow-up duration was 81.3%. Dysmenorrhea completely resolved in 32.6%. Moreover, 1.4% of patients became pregnant during follow-up. By the end of follow-up, four (1.9%) patients had a hysterectomy due directly to treatment failure. Conclusion: This study showed that EA surgery with Cavaterm Thermal Balloon was an effective treatment for AUB. The procedure was safe and was associated with a very low rate of postoperative adverse events. The patient satisfaction rate was favorable.
