Study Objective:
To evaluate high-intensity focused ultrasound (HIFU) ablation therapy for abdominal wall endometriosis (AWE).
Design:
A retrospective study.
Setting:
Gynecologic department of a teaching hospital in China.
Patients:
Thirty patients with AWE were treated from May 2013 to December 2015.
Interventions:
Thirteen patients were treated with HIFU ablation and 17 patients 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 2 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 post-treatment 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 = .043) in the HIFU ablation group were significantly lower than that of the surgical group.
Conclusions:
HIFU ablation therapy is a promising treatment for AWE, and further study is warranted.

Ultrasound I: Abdominal Ultrasonography
Abdominal ultrasonography, commonly known as abdominal ultrasound, is a vital, non-invasive medical imaging technique widely used in healthcare.
Procedure:
This diagnostic tool allows the clinician to visually inspect internal structures within the abdomen, including vital organs such as the liver, gallbladder, pancreas, kidneys, and spleen.
The abdominal ultrasound process begins with applying a special gel to the patient's skin over the abdomen. This gel enhances the...
