Objective The aim of this study was to compare the therapeutic outcomes of high-intensity focused ultrasound (HIFU) and surgical treatment for abdominal wall endometriosis.Design A retrospective study.Setting Gynaecological department of a teaching hospital in China.Population Patients with abdominal wall endometriosis.Methods Among the 51 patients, 23 patients were treated with ultrasound-guided HIFU and 28 patients with surgery. Pain relief and the size change of the nodule after each management were evaluated 1, 3, 6 and 12 months after treatment, respectively. The hospital stay and blood loss were also compared.Main outcome measures Difference between HIFU and surgical treatment for abdominal wall endometriosis.Results No statistically significant differences were observed between the two groups in the pain relief in 1, 3, 6 and 12 months after treatment, respectively. The hospital stay was clearly shorter in the HIFU group than in the surgery group. Change in nodules was more remarkable in the group treated with surgery; no palpable nodules existed in most patients in the surgery group. HIFU had more advantages over surgery, such as no blood loss, no new scar, no anaesthesia and lower pain score immediately after treatment.Conclusions Based on our results, it appears that either HIFU or surgery is safe and effective in treating patients with AWE in short-term. Compared with surgery, HIFU treatment for AWE has the advantages of shorter hospital stay, no blood loss, no new scar, no anaesthesia and a lower immediate pain score.Keywords Abdominal wall endometriosis, efficacy, high-intensity focused ultrasound, safety.Tweetable abstract Either HIFU or surgical treatment is safe and effective in treating patients with AWE. HIFU has the advantages of a less invasive procedure and shorter hospital stay.Please cite this paper as: Zhu X, Chen L, Deng X, Xiao S, Ye M, Xue M.

Objective The aim of this study was to evaluate the safety and efficacy of a combination of high-intensity focused ultrasound (HIFU) and hysteroscopic resection while treating placenta accreta (PA).Design A retrospective study.Setting A university teaching hospital in China.Methods This study included 25 patients diagnosed with PA who underwent HIFU followed by hysteroscopic resection in our hospital between January 2014 and December 2015. All patients had completed follow-up data. Treatment efficacy and safety were evaluated retrospectively.Main outcome measures Placenta accreta could be removed with hysteroscopic resection after HIFU.Results All patients received one session of HIFU ablation therapy. The median total HIFU treatment time was 18 minutes and the median exposure time was 600 seconds. During treatment, 23 lesions showed massive grey-scale changes and two lesions modest grey-scale change. Contrast-enhanced ultrasound showed signs of reduced perfusion in all lesions. During treatment, all patients tolerated the HIFU procedure well and completed the treatment. All patients complained of mild lower abdominal and sacrococcygeal pain, with a pain score ranging from 1 to 4 points. Seven patients complained of a 'hot' skin sensation. No serious complications were encountered during or after the procedure. All patients received hysteroscopic operations with a median of 2 days after HIFU treatment. The average depth of the uterus was 10.36 AE 2.14 cm. The median volume of intraoperative blood loss was 20 ml, and no blood transfusions were given. Sixteen patients underwent only one session of hysteroscopic resection and nine patients underwent a second session of hysteroscopic resection operation 11-61 days after the first operation. All patients preserved their uterus and tolerated the hysteroscopic operation well. Of the 25 patients, two had uterine perforation during the first operation. No other severe hysteroscopic complication was observed. The average hospital stay was 8.4 AE 1.6 days. After treatment the median duration of vaginal bleeding was 10 days. Twenty-one patients recovered normal menstruation 34 days after the operation. The other four patients continued breastfeeding and therefore exhibited abnormal menstruation.Conclusions HIFU treatment followed by hysteroscopic resection is safe and effective in treating patients with PA.Keywords Effectiveness, high-intensity focused ultrasound, hysteroscopy, placenta accreta, safety.Tweetable abstract For patients with placenta accreta, HIFU treatment before hysteroscopic resection could help reduce risk during the procedure of hysteroscopic resection.Please cite this paper as: Ye M, Yin Z, Xue M, Deng X.
