Disposable circumcision suture devices versus Shang ring circumcision for management of redundant prepuce or phimosis: A systematic review and meta-analysis

Abstract

ObjectiveTo evaluate the clinic efficacy and safety of the disposable circumcision suture device (DCSD) and Shang ring circumcision (SRC) in the treatment of redundant prepuce or phimosis with a meta-analysis. Material and methodsElectronic databases including PubMed, Embase, Wan Fang, VIP, CNKI and CBM database were researched from inception to August 30, 2016 for relevant RCTs and prospective studies, the reference lists of the included studies were also searched manually. The risk ratios (RR) or mean difference (MD) with 95% confidence intervals (CI) as the effect sizes were calculated by the Revman 5.3 and stata12.0 software. ResultsTwelve RCTs or prospective studies were included with 3345 patients among which 1661 cases received DCSD treatment and 1684 SRC. Compared to the Shang ring circumcision treatment, the disposable circumcision suture device provided a significantly shorter operation time [MD=−0.94, 95%CI (−1.76, −0.12), P=0.02], lower pain scores [MD=−1.89, 95%CI (−2.72, −1.07), P<0.001], no stitch removal pain, better postoperative penile appearance [RR=1.10, 95%CI (1.04, 1.17), P=0.001], fewer complications [RR=0.42, 95%CI (0.32, 0.56), P<0.001] and shorter wound healing time [MD=−8.92, 95%CI (−10.79, −7.05), P<0.001]. Meanwhile, there is more intraoperative blood loss [MD=0.12, 95%CI (0.02, 0.22), P=0.02], and more treatment cost [MD=877.57, 95%CI (737.94, 1017.20); P<0.001]. ConclusionsBased on the results of our meta-analysis, DCSD is more effective and safer than SRC. Thus, it has the advantages of shorter operation time, lower pain scores, better postoperative penile appearance, fewer complication and shorter wound healing time. However, the results need additional high-quality multicenter RCTs to evaluate in the future.
