Incidence of surgical site infections with triclosan-coated monofilament versus multifilament sutures in elective colorectal surgery.

Purpose: Surgical site infections (SSIs) are the most frequent complication of abdominal surgery. Using triclosan-coated sutures for abdominal wall closure reportedly reduces the incidence of SSIs. However, the SSI incidence has not been compared between the use of triclosan-coated multifilament and triclosan-coated monofilament sutures. We, therefore, compared the incidence of incisional SSIs between the use of triclosan-coated polyglactin 910 sutures (Vicryl Plus) and triclosan-coated polydioxanone sutures (PDS Plus). Methods: This observational cohort study was conducted on 318 consecutive patients who underwent elective colorectal cancer surgery at the Shiga University of Medical Science Hospital from January 2015 to December 2018. Based on the suture type for abdominal wall closure, 151 patients were enrolled in the PDS Plus group, and 167 were enrolled in the Vicryl Plus group. Results: The two suture groups were not significantly different in terms of risk factors for SSIs. Other postoperative complications also did not differ markedly between the two groups. In the multivariate logistic regression analysis, the presence of stoma was the only independent risk factor for incisional SSIs. Conclusion: The incidence of incisional SSIs was unaffected by the type of triclosan-coated sutures. The presence of stoma was an independent risk factor for incisional SSIs. [ABSTRACT FROM AUTHOR]
