High-intensity focused ultrasound for endometrial ablation in adenomyosis: A clinical study

Abstract

Abstract This study aimed to investigate the clinical efficacy of endometrial ablation with high-intensity focused ultrasound (HIFU) for symptom relief in women with adenomyosis. Between July 2014 and July 2020, 167 patients with adenomyosis treated at the Zhongshan City People’s Hospital were enrolled in this study. Patients were divided into two groups according to patient aspirations: the control group, including patients who only underwent ablation of adenomyosis lesions (group A) and the treatment group, including patients who underwent removal of adenomyosis lesions and endometrial ablation (group B). The reduced dysmenorrhea scores (visual analog scale) and menstrual volume scores (pictorial blood assessment chart) were measured before and after treatment. Scores were obtained by subtracting postoperative scores from preoperative scores and were compared to determine whether the symptoms had alleviated. Compared with the menstrual volume of group A, group B showed significant improvements. The average relief rates of dysmenorrhea in the two groups also showed significant improvement. However, the scores in group B showed significant improvement compared with those in group A. Therefore, the findings suggest that endometrial ablation using HIFU may be superior to conventional therapy for adenomyosis at improving the symptoms of increased menstruation.
