Triclosan-coated barbed sutures in elective laparoscopic colorectal cancer surgery: a propensity score matched cohort study

Abstract

Abstract Background Most of the studies published to date which assess the role of antibacterial sutures in surgical site infection (SSI) prevention include heterogeneous groups of patients, and it is therefore difficult to draw conclusions. The objective of the present study was to investigate whether the use of Triclosan-coated barbed sutures (TCBS) was associated with a lower incidence of incisional SSI and lower duration of hospital stay compared to standard sutures, in elective laparoscopic colorectal cancer surgery. Method Observational including patients who underwent elective colorectal cancer laparoscopic surgery between January 2015 and December 2020. The patients were divided into two groups according to the suture used for fascial closure of the extraction incision, TCBS vs conventional non-coated sutures (CNCS), and the rate of SSI was analysed. The TCBS cases were matched to CNCS cases by propensity score matching to obtain comparable groups of patients. Results 488 patients met the inclusion criteria. After adjusting the patients with the propensity score, two new groups of patients were generated: 143 TCBS cases versus 143 CNCS cases. Overall incisional SSI appeared in 16 (5.6%) of the patients with a significant difference between groups depending on the type of suture used, 9.8% in the group of CNCS and 1.4% in the group of TCBS (OR 0.239 (CI 95%: 0.065–0.880)). Hospital stay was significantly shorter in TCBS group than in CNCS, 5 vs 6 days (p < 0.001). Conclusion TCBS was associated with a lower incidence of incisional SSI compared to standard sutures in a cohort of patients undergoing elective laparoscopic colorectal cancer surgery.
