The purpose of this meta-analysis was to systematically assess the efficacy of ultrasound-guided therapy of ovarian endometriosis cyst (OEC). Several databases were searched to gather published studies on the efficacy of ultrasound-guided treatment of OEC. The period of publication of the included studies was January 1, 2000 to December 31, 2020. Two researchers screened the literature and extracted data independently. The publication bias of the obtained studies was assessed. The obtain data was analyzed by a meta-analysis. Ten literatures ware included in this meta-analysis, including 2379 patients in the control group (laparoscopic cyst resection) as well as 1244 in the study group (ultrasound-guided interventional therapy). In contrast to the control group, the study group had higher treatment effectiveness rate, shorter operative duration, lower incidence of adverse reactions, higher luteinizing hormone level as well as lower follicle-stimulating hormone level. We conclude that ultrasound-guided treatment of OEC is conducive to improving the clinical treatment effect, reducing the effective rate of treatment, shortening the operative duration, decreasing the incidence of postoperative adverse reactions, increasing the luteinizing hormone level and decreasing the folliclestimulating hormone level, which can effectively protect female's ovarian function, and is worthy of promotion and application.
