High-intensity focused ultrasound ablation versus surgical resection for
treating abdominal wall endometriosis: a systematic review and
meta-analysis
Abstract
Background Abdominal wall endometriosis (AWE) is the most
common type of extrapelvic endometriosis in women of reproductive age,
and several studies have compared high-intensity focused ultrasound
(HIFU) ablation with surgical resection in the management of AWE;
however, the results are controversial. Objective To compare
the efficiency and safety of HIFU ablation with surgery in the treatment
of AWE. Search strategy Literature on surgery versus HIFU
ablation for treating AWE was identified using the PubMed, Embase, Web
of Science, China National Knowledge Infrastructure, WANFANG Database
and the Cochrane Library databases. Selection Criteria
Full-text manuscripts comparing HIFU ablation and surgery for treating
AWE were included. Data collection and analysis Two independent
reviewers reviewed and extracted data from the articles, and the risk of
bias was assessed according to the Cochrane Handbook for Systematic
Reviews of Interventions. Data analysis was performed using RevMan 5.4.
Main results We included 7 studies involving 405 patients.
Compared with the surgery group, the immediate posttreatment visual
analogue scale (VAS) score was lower in the HIFU group (mean difference
[MD] -1.58, 95% CI -2.56 to -0.59), the length of hospitalization
was shorter in the HIFU group (MD -1.95 days, 95% CI −2.43 to −1.48),
and the incidence of adverse events was lower in the HIFU group
(relative risk 0.32, 95% CI 0.15 to 0.65). There was no significant
difference in the symptom recurrence rate, VAS score at the 3-, 6- and
12-month follow-ups, or treatment time between the two groups.
Conclusions Compared with surgery, immediate postoperative VAS
scores were lower, hospitalization times were shorter, and the risk of
adverse events were lower in patients receiving HIFU ablation treatment
for AWE.
