SP9.2.3 Role of single or double ringed circumferential wound protectors in reducing surgical site infections following colorectal resections: an evidence synthesis by the meta-analysis of randomized controlled trials

Abstract

Objective The objective of this article is to explore whether the use of single or double ringed wound protectors (WP) in patients undergoing colorectal resection (CRR) is associated with reduced risk of surgical site infections (SSI). Method Analysis was conducted according to PRISMA guidelines. With the help of expert local librarian, systematic search of medical databases like MEBASE, MEDLINE and pubmed was conducted to find appropriate randomized controlled trials (RCT) according to predefined inclusion criteria. The analysis of the pooled data was done using the principles of meta-analysis on statistical software RevMan. Result Eighteen RCT on 3744 patients fulfilled the inclusion criteria. There were 1885 patients in the WP group and 1889 patients in the no-WP group. In the random effects model analysis, the use of WP during CRR was associated with the reduced risk of SSI [odds ratio 0.63, 95% CI (0.47–0.86), z= 2.94, p=0.003]. However, there was significant heterogeneity (Tau2 = 0.18; Chi2= 34.77, df = 17; (p=0.007; I2 = 51%) among included studies. Conclusion Use of WP seems to reduce the risk of SSI and therefore, may routinely be used during both open and laparoscopic CRR.
