Abstract: Objective：To compare the effectiveness of bipolar electrosurgical excision procedure and monopolar hysteroscopic operations in the treatment of uterine disease. Methods：Such databases as Medline，Embase，The Cochrane Library，CNKI，CBM，Wanfang Data were electronically searched. According to the inclusion and exclusion criteria，literature was screened，data were extracted，and the methodological quality of included studies were also assessed by two researchers. Then，meta-analysis was performed using RevMan 5.2 and stata12.0 software. Results：20 studies with 4 418 participants were included. Evidence was found that there were statistical differences in operation time，amount of blood loss，hospitalization time，blood electrolyte and blood glucose（P＜0.05）. Conclusions：The common clinical uterine cavity operation can be finished by bipolar electrosurgical excision procedure and monopolar hysteroscopic operations，but bipolar electrosurgical excision procedure has the priority in operation time，amount of blood loss，hospitalization time and blood electrolyte，and it′s worthy to be recommended in clinic.
