Evaluation of a novel technique for wound closure using a barbed suture
ABSTRACT Suture knots present several disadvantages in wound closure, because they are tedious to tie and place ischemic demands on tissue. Bulky knots may be a nidus for infection, and they may extrude through skin weeks after surgery. Needle manipulations during knot-tying predispose the surgeon to glove perforation. A barbed suture was developed that is self-anchoring, requiring no knots or slack management for wound closure. The elimination of knot tying may have advantages over conventional wound closure methods.
This prospective, randomized, controlled trial was designed to show that the use of barbed suture in dermal closure of the Pfannenstiel incision during nonemergent cesarean delivery surgery produces scar cosmesis at 5 weeks that is no worse than that observed with conventional closure using 3-0 polydioxanone suture. Cosmesis was assessed by review of postoperative photographs by a blinded, independent plastic surgeon using the modified Hollander cosmesis score. Secondary endpoints included infection, dehiscence, pain, closure time, and other adverse events.
The study enrolled 195 patients, of whom 188 were eligible for analysis. Cosmesis scores did not significantly differ between the barbed suture group and the control group. Rates of infection, dehiscence, and other adverse events did not significantly differ between the two groups. Closure time and pain scores were comparable between the groups.
The barbed suture represents an innovative option for wound closure. With a cosmesis and safety profile that is similar to that of conventional suture technique, it avoids the drawbacks inherent to suture knots.

ABSTRACT: Barbed sutures may expedite dermal approximation and improve tissue support while requiring less time and material than conventional sutures. Several types of barbed sutures are available, each with unique advantages. The authors sought to determine whether the incidence of complications differed after wound approximation in plastic surgery when various brands of barbed vs nonbarbed traditional sutures were employed. The authors conducted a retrospective review of outcomes in body contouring, free flap, and breast reconstruction. Suture type and closure method were noted for each case. The number of complications after traditional 2-layer closure with nonbarbed sutures was compared with the number of complications after closure via 1- and 2-layer techniques with several brands of barbed sutures, and the brands of barbed sutures were compared with each other. A total of 1011 unique surgical procedures, including 298 procedures with barbed sutures and 713 procedures with nonbarbed sutures, were performed by 5 members of the plastic surgery faculty. The 2-layer technique with barbed sutures was associated with significantly higher rates of wound separation than traditional methods. Excessive erythema along the incision site was significantly more frequent with Quill barbed sutures than with V-Loc barbed sutures. Barbed sutures were associated with significantly higher rates of minor wound complications, specifically when the 2-layer closure technique was performed. Significantly higher rates of erythema were associated with Quill barbed sutures than with V-Loc barbed sutures.

ABSTRACT: Traumatic tendon lacerations are a common problem encountered by hand surgeons worldwide. Although the use of barbed suture to repair tendon lacerations has gained theoretical popularity in recent years, there is little information available regarding the safety, efficacy, longevity, or complications encountered when used in tenorraphy. In this study, we review the available literature on the use of barbed suture in tendon repair. Studies conducted between 1980 and 2014 were identified using several databases, including EMBASE, SCOPUS, MEDLINE, and Web of Science. Keywords used to search for appropriate studies included the following: barbed, v loc, quill, tendon, tendon injuries, suture, tenorraphy, injury, and laceration, in various combinations. Our initial literature search identified 47 articles, and 8 were deemed appropriate for review after applying our exclusion criteria. The data from each of the articles is reviewed for the following major categories:Maximum load to failureMode of failureLoad to 2-mm gapChange in cross-sectional areaType of repair. Barbed suture tenorraphy has a myriad of theoretical advantages, supported by varying ex vivo studies, as compared to traditional techniques. However, due to the non-uniformity in current studies and the lack of available data in a live model, we are unable to argue for or against barbed suture tenorraphy. We believe our review provides the most in-depth analysis of barbed suture tenorraphy to date, illuminates the potential advantages of using barbed sutures, and highlights the need for further investigation into this technique.Hand 01/2014; 10(1).
