Abstract

OBJECTIVE: To compare the clinical efficacy of High intensity-focused ultrasound(HIFU) for different types of adenomyosis classified by magnetic resonance imaging (MRI). METHODS: A total of 227 patients with adenomyosis who underwent HIFU treatment in Suining Central Hospital from January 2014 to December 2019 were included. Based on the preoperative pelvic MRI examination and Kishi isometric classification method, the patients were divided into 4 types according to the location of lesions. There were 82 cases of type I (endogenous type), 75 cases of type II (exogenous type), 34 cases of type III (nodular type), and 36 cases of type IV (heterogeneous type). The results of HIFU treatment for four types of adenomyosis and intraoperative adverse effects were analyzed. The changes of lesion size, dysmenorrhea, and menstrual volume were analyzed at 3 and 6 months after the operation. RESULT: (1) adverse effects: All patients successfully accepted HIFU treatment under sedation and analgesia. Grade A adverse effects occurred in 51 cases (22.47%) and grade B adverse effects in 3 cases (1.32%). The incidence of adverse effects in type I-IV patients was 21.95%, 22.66%, 23.53%, and 30.56%, respectively. There was no significant difference in the incidence of grade A and B adverse effects in all types, and no grade C-F adverse effects occurred. (2) Ablation effect: The ablation rate of type III(nodular type)patients was (74.7 ± 20.3) %, which was significantly higher than that of the other three types (p < .05). (3) Changes in lesion size: the lesion size of all patients decreased after treatment and the reduction rate gradually increased with time. At 6 months after the operation, the lesion reduction rate of type III patients was (70.8 ± 14.8) %, higher than that of the other three types patients (p < .05). There was no significant difference in the reduction rate of type I, type II and type IV. (4) Remission of menorrhagia: At 6 months after the operation, the total remission rate of type III patients was 100%, while the total remission rate of type IV patients (65.4%, 17/26) that was lower than that of type I, II and III patients(p < .05). (5) Dysmenorrhea relief: At 6 months after the operation, the total dysmenorrhea relief rate of type III patients was 100% and the complete relief rate (28.1%, 18/31) was higher than that of the other three types, which was significant differences (p < .05). CONCLUSIONS: HIFU is safe and effective in the treatment of different types of adenomyosis, the therapeutic effect of HIFU in patients with type III adenomyosis is better than that of the other three types.
