Wire Cerclage Versus Cable Closure After Sternotomy for Dehiscence and DSWI: A Systematic Review and Meta-Analysis.

Overview

OBJECTIVE: Cable closure has been introduced as a potential alternative to traditional wire cerclage (WC) for closure of median sternotomy. To evaluate whether cable closure improves patient outcomes, we conducted a systematic review and meta-analysis of the literature. METHODS: Ovid versions of Medline and Embase, and Google Scholar were used for the literature search. This yielded 7 studies (n = 2,758), which compared traditional WC to cable closure systems. Outcomes included deep sternal wound infection, sternal dehiscence, postoperative pain score, and sternal wound infection. RESULTS: We found significantly lower incidence of sternal dehiscence for cable closure compared to WC (risk ratio [RR] 0.14, 95% confidence interval [CI]: 0.03 to 0.59, P < 0.01, I ² = 0%) but no difference in DSWI (RR 0.97, 95% CI: 0.39 to 2.42, P = 0.95, I ² = 33%). Cable closure was also associated with lower pain when compared with the WC group (mean difference -1.04 points, 95% CI: -1.89 to -0.19, P = 0.02, I ² = 87%). CONCLUSIONS: This study suggests that cable closure results in less incidence of sternal dehiscence and pain compared to WC. Nonetheless, there remains a limited number of studies on this topic and further high-quality studies are required to confirm the results of this meta-analysis.
