Incisional Surgical Site Infection after Abdominal Fascial Closure with Triclosan-Coated Barbed Suture vs Triclosan-Coated Polydioxanone Loop Suture vs Polydioxanone Loop Suture in Emergent Abdominal Surgery: A Randomized Clinical Trial.

BACKGROUND

Triclosan-coated sutures have been shown to reduce surgical-site infection (SSI) in emergent operation for fecal peritonitis. Barbed sutures provoke a homogeneous distribution of tension throughout the suture, implying better blood supply to the wound edges and healing. The aim of this study was to evaluate the effect, on SSI and evisceration, of using triclosan-coated and barbed sutures for fascial closure in patients undergoing emergent surgery.

STUDY

DESIGN

A prospective, randomized clinical trial was performed. Patients were randomized into 3 groups: those undergoing aponeurotic closure with triclosan-coated barbed suture (Stratafix Symmetric [Johnson & Johnson]), patients undergoing closure with triclosan-coated polydioxanone loop suture (PDS plus [Johnson & Johnson]), and patients undergoing closure with polydioxanone loop suture (PDS [Johnson & Johnson]). Primary investigated outcomes were SSI and evisceration rates during a follow-up period of 30 days. The primary analysis plan was based on a per-protocol approach.

RESULTS

Incisional SSI was 6.4% (3 of 47) in the Stratafix Symmetric group, 8.9% (4 of 45) in the PDS plus group, and 23.4% (11 of 47) in PDS group (p = 0.03). The evisceration rate was 0% in Stratafix Symmetric, 8.9% (4 of 45) in PDS plus, and 12.8% (6 of 47) in PDS (p = 0.05). Median hospital stay was 4 days (range 2 to 14 days) in Stratafix Symmetric, 5 days (range 2 to 21 days) in PDS plus, and 8 days (range 2 to 60 days) in PDS (p = 0.012). The use of triclosan-coated sutures (Stratafix Symmetric and PDS plus) was associated with a lower risk of incisional SSI (p = 0.009), and the use of barbed suture was associated with a lower risk of evisceration (p = 0.019). Comparing Stratafix Symmetric with PDS plus, there were no significant differences in SSIs, but the evisceration rate was significantly higher in the PDS plus group (p = 0.036).

CONCLUSIONS

The use of triclosan-coated sutures (Stratafix Symmetric and PDS plus) in emergent surgery reduces the incidence of incisional SSIs. The use of barbed sutures reduces the incidence of evisceration.
