Ultrasound-guided high-intensity focused ultrasound treatment for abdominal wall endometriosis: a retrospective study.
OBJECTIVE
To evaluate the safety and efficacy of ultrasound-guided high-intensity focused ultrasound (USgHIFU) for treating abdominal wall endometrioses (AWE).


DESIGN
A retrospective study.


SETTING
Department of Obstetrics and Gynaecology in China.


POPULATION
Patients with abdominal wall endometriosis.


METHODS
From August 2010 to April 2014, 32 patients with AWE were treated with USgHIFU in our hospital. USgHIFU treatment was performed with the Model JC-200 High Intensity Focused Ultrasound Tumor Therapeutic System. The symptom relief and the adverse effects were evaluated after USgHIFU ablation.


MAIN OUTCOME MEASURES
USgHIFU as a new treatment option for patients with AWE.


RESULTS
Contrast-enhanced ultrasound showed that all lesions were successfully ablated with USgHIFU. The follow-up results showed that the average volume of AWE lesions at 6 months after USgHIFU was significantly smaller than that before treatment (2.80 ± 0.12 versus 1.33 ± 0.31 cm3 ). The pain scores at 6 months after treatment were significantly lower than those before treatment (6.80 ± 2.64 versus 1.80 ± 0.3). The non-perfused volume (indicative of successful ablation) was measured in all patients immediately after treatment, ranging from 0.9 to 2.1 cm3 (median: 1.6 cm3 ), and the fractional ablation ranged from 87% to 100% (median: 94%). Local oedema was observed in these patients, lasting for 1-3 days only. No severe complications occurred during the follow-up period.


CONCLUSIONS
Based on our study, USgHIFU ablation is a safe and effective method for treating AWE.


TWEETABLE ABSTRACT
As a non-invasive treatment technique, HIFU could be used to treat abdominal wall endometriosis.
