STUDY OBJECTIVE To evaluate high-intensity focused ultrasound (HIFU) ablation therapy for abdominal wall endometriosis. DESIGN A retrospective study. SETTING Gynecological department of a teaching hospital in China. PATIENTS Thirty patients with abdominal wall endometriosis were treated from May 2013 to December 2015. INTERVENTIONS Thirteen patients were treated with HIFU ablation, and 17 patients were treated with surgical resection. MEASUREMENTS AND MAIN RESULTS Color Doppler ultrasonography and magnetic resonance imaging were used to observe the lesions before and after treatment. In addition, recovery time, complications, and adverse reactions of the two groups were compared. Menstrual pain was relieved after treatment in all 30 patients. After treatment, the lesions in patients who underwent HIFU ablation decreased gradually, and there was no recurrence. Symptoms recurred in 1 patient in the surgery group 12 months after surgery. The posttreatment hospital length of stay of the HIFU ablation group (1.00 ± 0 days) was significantly shorter than that of the surgical group (5.23 ± 1.24 days; p < .001). The incidence of fever (0% vs 11.8%; p = .049) and complications of the urinary system (7.7% vs 17.6%; p = .43) in the HIFU ablation group was significantly lower than that of the surgical group. CONCLUSIONS High-intensity focused ultrasound ablation therapy is a promising treatment for abdominal wall endometriosis, and further study is warranted.
