Objective To assess the efficacy and safety of focused ultrasound (FU) and microwave therapy (MW) for cervical ectopy (CE). Methods We searched the following databases:PubMed, EMbase, The Cochrane Library, CBM, VIP, CNKI and WanFang Data from inception to 30th August 2014. Two reviewers (Tang XL and Gao Z) independently screened literatures according to the inclusion and exclusion criteria, extracted data and assessed the methodological quality of included studies. Then, meta-analysis was performed by using RevMan 5.2.0 software. Results A total of 33 randomized controlled trials (RCTs) involving 1 759 patients were included. All the included studies were considered to be at high risk of bias. The results of meta-analysis showed that:compared with MW, FU could significantly reduce the risk of vaginal bleeding (RR=0.09, 95%CI 0.05 to 0.17, P<0.000 01) and vaginal discharge (RR=0.10, 95%CI 0.04 to 0.24, P<0.000 01), increase cure rate (RR=1.10, 95%CI 1.05 to 1.15, P<0.000 1) and total effective rate (RR=1.04, 95%CI 1.02 to 1.06, P=0.000 5). However, there was no difference in decreasing recurrence rate (RR=0.13, 95%CI 0.02 to 1.00, P=0.05). Conclusion Current available evidence suggest that FU is safer and more effective than MW for treating CE. Due to the limitation of quality of included studies, more high quality RCTs are needed to verify the above conclusion.
