Combination therapeutic effects of high intensity focused ultrasound and Metformin for the treatment of adenomyosis.

Adenomyosis is a pathological gynaecological condition characterized by benign invasion of the endometrium into the myometrium. High intensity focused ultrasound (HIFU) is one of the most common therapeutic strategies for the treatment of adenomyosis. However, the efficacy of single HIFU therapy is insufficient for the treatment of patients with adenomyosis. In the present study, the efficacy of HIFU and metformin for the treatment of adenomyosis was analyzed in 274 patients with adenomyosis who were admitted to Jinan Maternity and Child Care Hospital. The results demonstrated that there was a significant reduction in menstrual flow and pain between patients who received HIFU and metformin, and those who received single HIFU treatment (P<0.01). Furthermore, the outcomes demonstrated that inflammatory cytokines levels were significantly lower compared with the baseline values (P<0.01). In conclusion, the outcomes of the current study indicate that combined HIFU and metformin treatment is more efficacious in patients with enlarged adenomyosis compared with single HIFU treatment.
