Abstract：Objective:To compare the effect and safety of the no-flip method versus the external method in Shang Ring circumcision.Methods:We searched relevant randomized controlled trials published in China and abroad comparing the no-flip method and external method of Shang Ring circumcision.Based on the Cochrane Handbook for systematic review,two reviewers independently evaluated the quality of the included studies and abstracted relevant data,followed by a meta-analysis using the statistical software Review Manager 5.1.0.Results:Totally 7 studies with 1 200 cases were included.Compared with the external method,the no-flip method was associated with a lower total rate of complications (RR =0.40,95％ CI:0.18,0.87,P =0.02),a lower incidence of postoperative edema (RR =0.28,95％ CI:0.09,0.81,P =0.02),and a lower 24 h postoperative pain score (MD =-0.35,95％ CI:-0.55,-0.14,P ＜ 0.001).Conclusion:The no-flip method of Shang Ring circumcision was superior to the external method for its advantages of fewer complications,lower incidence of postoperative edema,and mild postoperative pain.However,our findings need further support by more high-quality randomized controlled trials.
