Abstract:

Objective: To compare the clinical effect of high-intensity focused ultrasound (HIFU) ablation and surgery in the treatment of abdominal wall endometriosis (AWE). Methods: The clinical data of 262 AWE patients hospitalized in Beijing Obstetrics and Gynecology Hospital, Capital Medical University from January 2015 to November 2019 were retrospectively analyzed. According to the treatment modality, the patients were divided into HIFU group (n=64) and surgery group (n=198), comparing the operation time, intraoperative bleeding, hospital stay, postoperative lesion size, pain level, clinical efficiency and complications. Results: The median operation time in the HIFU group was 34.5 (22.3, 47.3) min, which was significantly shorter than 40.0 (30.0, 60.0) min in the surgery group (Z=-3.112, P=0.002). The median hospital stay in the HIFU group was 2.0 (2.0, 3.0) days, which was shorter than 7.0 (6.0, 8.3) days in the surgery group (Z=-11.982, P=0.000). There was no significant difference in clinical efficiency between 2 groups (χ2=-1.207, P=0.227). In the HIFU group, ultrasound follow-up was performed 1, 3 and 6 months after treatment. The ablation rates were (88.25±13.09)%, (92.33±9.18)%, (98.67±4.09)%, respectively. By the 12th month after operation, the ablation rates were 100.00%. The volume of lesions before treatment was significantly different from that at 1, 3, 6 and 12 months after treatment (P<0.05). There was significant difference in the degree of periodic pain between the HIFU group and the surgery group at 3, 6 and 12 months after treatment (P<0.05). The rate of adverse reactions was 6.25% (4/64) in the HIFU group and 3.54% (7/198) in the surgery group, and there was no statistically significant difference between 2 groups (χ2=0.340, P=0.560). Conclusions: HIFU ablation for AWE is comparable to surgical resection, but it is superior to surgical resection in terms of shortening procedure time, reducing hospital stay and alleviating postoperative pain, making HIFU ablation one of the safe and effective options available to AWE patients.
