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: Surgical knots are simply a necessary evil needed to anchor smooth suture to allow it to function in its role in tissue reapproximation. Surgical knots reduce the tensile strength of all sutures by thinning and stretching the material. The tying of surgical knots introduces the potential of human error and interuser variability. Knot-secured smooth suture must create an uneven distribution of tension across the wound with the higher tension burdens placed at the knots. Given the excessive relative wound tension on the knot and the reasonable concerns of surgeons for suture failure due to knot slippage, there is a natural tendency toward overcoming these concerns by over-tightening knots; however, tighter knots may be worse for wound healing and strength than looser knots. In minimally invasive laparoscopic surgeries, the ability to quickly and properly tie surgical knots presents a new challenge. In cases in which knot tying is difficult, the use of knotless barbed suture can securely reapproximate tissues with less time, cost, and aggravation. This article reviews the technology behind barbed sutures with a focus on understanding how they differ from traditional smooth sutures and how barbed sutures have performed in in vitro and animal model testing, as well as in human clinical trials.

    ABSTRACT: Neste artigo é apresentado um instrumento cirúrgico alternativo para suspensão da camada fibroadiposa do terço médio da face. A agulha foi confeccionada com fio de Kirschner, de forma que ambas as pontas se tornaram rombas. A dupla ponta possibilita a passagem do fio pelo sistema musculoaponeurótico superficial da face (SMAS), mantendo a sutura com a profundidade necessária para evitar dermatografia. Os testes com o novo instrumento foram realizados em ritidoplastias com dissecção mínima. A agulha descrita demonstrou-se segura, com fácil migração pelos tecidos e ausência de lesões vasculonervosas, facilitando o posicionamento dos pontos de fixação nos locais planejados. A agulha desenvolvida possibilitou a realização da ritidoplastia sem descolamento resultante de forma rápida, simples e custo-efetiva, com mínimo dano às estruturas anatômicas e aos tecidos.
