absorbable suture material

(Table 11.4) P4HB fibers are stronger than commonly used PP sutures (410–460 MPa) and at least comparable in strength to commercially absorbable materials like Maxon (540–610 MPa) and PDS II (450–560 MPa) (Chu et al., 1997). 13-21). Internal wound closure yields the best results when using an absorbable material. TISSUE FRIENDLY. The latest addition to the synthetic absorbable suture materials is TephaFLEX which is thermally melt-spun from poly-4-hydroxybutyrate, a member of the class of absorbable biomaterials known as polydroxyalkanoates, or PHA (FDA, 2007; Martin and Williams, 2003). The time in which this absorption takes place varies between material, location of suture, and patient factors. These results were consistent with the Osterberg and Blomstedt study (1979) on the level of inflammatory cell reaction near implanted and infected suture sites. Polyglactin-910 (Vicryl) is braided synthetic polymer also used for deep closures. C. describes the use of linen as suture material. The fact that polydioxanone is absorbable makes it an ideal candidate for internal wound closure. Objective: To evaluate the tensile strength and suture degradation of 5 commonly used absorbable suture materials in different pH and bacteria inoculated media. Our Dermalon™ monofilament nylon sutures are inert, non-absorbable, sterile surgical sutures, 1 available dyed blue to improve visibility. Sizes larger than 0 (1/0) are denoted by 1, 2, 3 etc. The EP standard does not separate natural from synthetic absorbable sutures as does USP. (Table 11.4) P4HB fibers are stronger than commonly used PP sutures (410–460 MPa) and at least comparable in strength to commercially absorbable materials like Maxon (540–610 MPa) and PDS II (450–560 MPa) (Chu et al., 1997). Common suture materials and suggested indications for their use Table of when to use different types of sutures Examples Synthetic or Natural Suggested Indications Absorbable Monofilament CatgutChromic Catgut Natural Rarely used PDS™ (Polydioxanone)Monocryl™ (Polycaprone Glycolide) Maxon™ (Polyglyconate) Synthetic Buried dermal sutures or continuous subcuticular suture Absorbable … Especially among older patients, preoperative ptosis should be identified, and it can be repaired during the blepharoplasty.39. Stitches which dissolve in body fluids to produce harmless products have been known for many years, the polymers of interest producing non-toxic monomers or starting units. P4HB polyester is naturally produced inside cells as storage granules that regulate energy metabolism. The material may not be completely absorbed at this point, but it will have lost the majority of its initial tensile strength. A newcomer to the absorbable suture family is TephaFlex® from Tepha which received FDA approval for marketing in April 2007 (FDA, 2007). The main reason for using the nail as a splint is to prevent adhesions and granulation tissue buildup between the eponychium and the germinal matrix of the bed. The mechanical qualities and biocompatibility of P4HB make it a more suitable absorbable suture than the currently available materials. P4HB polyester is naturally produced inside cells as storage granules that regulate energy metabolism. 10.2). One can either use absorbable or non-absorbable sutures when placing subcuticular sutures. It is one of the strongest absorbable suture materials available, allowing the selection of suture sizes that are one to two times smaller than would ordinarily be chosen.8,33 However, it rapidly loses its strength after implantation.24 Dyed monocryl retains 30–40% of its tensile strength at 2 weeks whereas undyed monocryl retains only 25% at 2 weeks. • The suture material is recognised as having a smooth feel and consistent thickness according to USP standards. Fractured test end of Vicryl suture. The unique ability of the polymer to be elongated almost ten times its original length is due to the orientation of the polymer chains, resulting in exceptionally strong fibers. Synthetic absorbable sutures may be made of polyglycolic acid, a glycolide-lactide copolymer; or polydioxanone, a copolymer of glycolide and trimethylene carbonate. The process of degradation depends on the material and range from ten days to eight weeks. The point of these is that the suture material should be absorbed by the body over a few weeks, after the tissue has healed. One-layer anastomoses are preferred by some surgeons. In terms of the physical configuration of the threads, sutures can also be classified into: Suture materials made of nylon, polyester and stainless steel are available in both multifilament and monofilament forms. Braided synthetic adsorbable multifilament made of polyglycolic acid and coated with N-laurin and L-lysine, which render the thread extremely smooth, soft and knot safe. Another natural product, braided silk fibre can also be used, and individual doctors will make a choice appropriate for particular kinds of wound. The amount of time this takes depends on the material, but also the location of insertion and the individual patient characteristics. Monocryl (3-0 or 4-0) and undyed Vicryl (3-0 or 4-0) are most commonly used. The plane chosen is either the dermis or just deep to the dermis in the superficial subcutaneous fascia. Its major advantage is that it can be used for skin closure without the need for removal. Kent Petrie MD, ... Walter L. Larimore MD, in, Family Medicine Obstetrics (Third Edition), Polyglycolic acid (PGA) (Dexon) currently is in widespread use as an, The Breast, 2-Volume Set, Expert Consult Online and Print (Fourth Edition), After the diseased portion of the duct is removed, the nipple is carefully reconstructed with no. Knots are well-known stress concentrators in ropes and cords, and behave similarly in braided fibre. Caprosyn™ synthetic absorbable suture’s quick absorption (56 days), durable polymer material and monofilament construction provide smooth passage through tissue, better approximation or ligation, and minimized potentiation of infection. Today we are going to discuss several of the many type of sutures as well as when they are indicated for use, suture material, and finally suture patterns that can be used. Using nonabsorbable wound closure material requires removal of the device after the wound has healed. If the nail cannot be used, a small piece of nonadherent dressing, such as Adaptic or a Penrose drain, can be tucked under the eponychium (Fig. This is to be expected, as hydrolysis of P4HB yields 4HB, which is a natural metabolite present in the brain, heart, lung, liver, kidney, and muscle (Nelson et al., 1981). 10.2. Characteristics of suture material. It is available in the dyed or the undyed form. (2000) reported that P4HB showed a near complete resorption histologically (169 days or 24 weeks) as a patch of the pulmonary artery of a juvenile sheep, and porosity of the P4HB patch material (> 95% porosity with pore sizes of 180–240 μm) has a direct effect on the loss of mass from the material in a subcutaneous environment. Market Research Future present a Prime Research Report “Absorbable Surgical Sutures Market Research Report – Forecast to 2023” The Increasing Demand for Advanced Wound Closure Materials and Lack of Product Innovations in Surgical Sutures act as Major Barriers for this Market. 13-25). In patients who present with inverted nipples or a retracted nipple secondary to a previously drained chronic disease site, the nipple is everted and a fourth suture consisting of a purse-string or Z-suture with no. Alternatively, the stitch could simply have not been tied correctly in the first place using approved knots and placements in the soft tissues to be joined together. Bidirectional barbed suture showing mid-point [150]. Hence, phagocytic activity is retarded. Although the failed suture had been unfortunately lost, equivalent new sutures were made available for inspection. The production of P4HB is performed through a proprietary transgenic fermentation process in the bacteria Escherichia coli, a microorganism that has become the workhorse of the biopharmaceutical industry. Complete absorption occurs between 60 and 90 days. The purpose of anti-bacterial surgical sutures are to minimise the damage on tissue or scarring. It is a synthetic adsorbable suture material. Silk is the most commonly used of the non-absorbable suture materials. In Slatter D. (1993) Textbook of Small Animal Surgery Second Edition. Studies have shown that TephaFLEX is both biocompatible and noninflammatory. Absorbable Suture Any suture material—catgut and biosynthetics, including polyglycolic acid, polylactic acid, polydioxanone, and caprolactone—which is left in place and removed by natural processes—e.g., hydrolysis and/or proteolytic degradation over a period of 2 to 8 weeks. Two monofilament absorbable suture materials, polyglyconate (Maxon) and polydioxanone (PDS), have some advantages over PGA and polyglactin-910. Biochemical Engineering Journal 16 (2003), 97–105. Table 10.A.1 in the Appendix at the end of this chapter summarizes all commercial absorbable and nonabsorbable suture materials that are available in the United States, Europe and the Pacific, their generic and trade names, their physical configurations, and the names of their manufacturers. The medical records show that following delivery of the baby, her uterus was stitched in two layers with Vicryl, and externally with Prolene (polypropylene). Properties of absorbable elastomeric P4HB copolymers incorporating 3HB. Absorbable sutures are ideal for internal wounds, such as those made after childbirth, but things may not always go to plan. Even a photograph of a failed product is better than no product at all, for much can be learnt from good photographs of failures. In addition, the molecular weight of the polymer can be controlled by controlling the enzymes in the engineered pathway, providing P4HB molecular weight up to approximately one million with polydispersity of 2–3 (Martin and Williams, 2003). The knotless designed suture increases the flexibility and longitudinal movement of the tendon that would normally be limited by the presence of knots. Dermalon™ Monofilament Nylon Sutures Visibility when you need it most. Mechanical properties of P4HB before and after orientation, Kent Petrie MD, ... Walter L. Larimore MD, in Family Medicine Obstetrics (Third Edition), 2008, In Wounds and Lacerations (Third Edition), 2005. Galen (200 AD) - used silk suture material. Appendix 2 at the end of this chapter provides a summary of these. Polyester and nylon based textiles in biomedical engineering, In 1992, Dr Gregory Ruff of Duke University Medical Center started working on an idea of a barbed suture for cosmetic applications. Resorbable sutures are typically used for surgical incisions that can't be accessed after surgery. Thus the septum should be opened more superiorly, where that fat pad is thicker. Polyglycolic acid (PGA) (Dexon) currently is in widespread use as an absorbable suture material (Table 8-1). It is hydrolyzed by body fluids at a rate comparable with wound healing, so has disappeared when it has fin-ished holding tissues together and the tissues are self-supporting. The following day the wound was clean with only slight oozing, and the paper sutures removed. Compared with PGA, plain gut and chromic gut appear to have inferior tensile strength and wound security.3,4 The main use of chromic gut is to close lacerations within the oral mucosa, perineum, and scrotal skin. This suggests that P4HB degrades by surface erosion rather than by bulk degradation as do PGA and PLA. In less complicated injuries, it is common for the nail root to avulse partially from the bed under the cuticle (eponychium). However, PGA has greater knot security. Absorbable suture materials are either natural or synthetic. Absorbable sutures are mostly used to suture internal body tissues. Monofilament absorbable sutures are preferable in contaminated wounds. Source: Data adapted from Martin, David P. and Simon F. Williams. The material may not be completely absorbed at this point, but it will have lost the majority of its initial tensile strength. Absorbable suture materials include the original catgut as well as the newer synthetics polyglycolic acid, polylactic acid, polydioxanone, and caprolactone. Depending on … Results are based on pre- clinical and bench testing. Table 11.3 shows the mechanical properties of P4HB in comparison to current synthetic absorbable biomaterials (Martin and Williams, 2003). Absorbable Suture Any suture material—catgut and biosynthetics, including polyglycolic acid, polylactic acid, polydioxanone, and caprolactone—which is left in place and removed by natural processes—e.g., hydrolysis and/or proteolytic degradation over a period of 2 to 8 weeks. Dr Ruff took the idea of a barbed suture and applied it to an, Poliglecaprone is a synthetic monofilament absorbable suture made of a copolymer of glycolide and ε-caprolactone. This standard also varies with the type of suture material. Barbed suture in tendon repair application [149]. The material is a copolyester of lactic acid and glycolic acid, both of which are harmless products easily excreted by the body: The lactic acid content is about 10% in Vicryl, the repeat units being randomly distributed among blocks of glycolic acid. The final bite leaves a trailing loop of suture (see Fig.11-4) so that the knot can be fashioned for final closure. Ethilon (nylon), silk, Prolene (polypropylene) Lasts longer than 60 days; Traditionally used for skin closure By continuing you agree to the use of cookies. An absorbable suture material (e.g., Dexon, Vicryl, PDS, Maxon, or Monocryl) can be used. Monofilament Dyloc (from Dynek, Australia) is unusual among synthetic nonabsorbable sutures because it is made from a nonconventional man-made fiber: poly(ether ester) (Fig. P4HB is not as strong as PGA, but it is far more pliable and flexible than PGA and PLA. A continuous strand of suture mounted on a spool for ligation purposes. 13-22). Copyright © 2021 Elsevier B.V. or its licensors or contributors. Table 11.4. A hemorrhage involving the levator muscle will compromise elevating function. The main types of material for both absorbable and nonabsorbable sutures are discussed in Chapter 11. Lister (1869) - introduction of suture sterilization and treatment of catgut with chromic acid. Dart, in Comprehensive Biomaterials, 2011, Poliglecaprone is a synthetic monofilament absorbable suture made of a copolymer of glycolide and ε-caprolactone. All surgeons performing blepharoplasty should have an excellent knowledge of orbital anatomy. The major distinguishing factor between P4HB and typical sutures is the handling during the wound closure process. When a surgeon is finishing a coccygectomy, they may suture up the flesh under the skin using Vicryl absorbable sutures. The company Ethicon publishes guidelines on their Vicryl suture (27), stating that the sutures retain 75% of their original tensile strength after 2 weeks implantation in rats, and 50% at three weeks. If intact, an avulsed or removed nail can be replaced, for temporary splinting purposes, under the eponychium (Fig. Gut is an organic material manufactured from sheep intestines. Both a greater intensity and a longer duration of reaction were found around capillary threads than around noncapillary materials. The latter include polypropylene, polyamide, polyester, poly(ether ester), polytetrafluoroethylene (Gore-Tex®), polyvinylidine fluoride (PVDF), and stainless steel. From: Wounds and Lacerations (Fourth Edition), 2012, Alexander T. Trott MD, in Wounds and Lacerations (Fourth Edition), 2012. This suggests that P4HB degrades by surface erosion rather than by bulk degradation as do PGA and PLA. In the EP standard, the code ranges from 0.1 to 10. ‘Medical applications of poly-4-hydroxybutyrate: a strong flexible absorbable biomaterial’. By 3 weeks, there is no residual strength, absorption is by hydrolysis and is complete by 90–120 days.9. 4HB, polymerized with other hydroxy acids such as 3-hydroxybutyrate (3HB), can yield elastomeric compositions at moderate 4HB contents (20–35%), and relatively hard rigid polyesters at lower 4HB contents (see Table 11.2) (Martin and Williams, 2003; Doi, 1990). Polyglactic 910 (ex, Vicryl) [ Hochberg, 2009 ] Retains 65% of its tensile strength at 2 weeks; 40% at 3 weeks. The mechanical qualities and biocompatibility of P4HB make it a more suitable absorbable suture than the currently available materials. Absorbable and Non-absorbable sutures Sutures can be divided into two types – those which are absorbable and will break down harmlessly in the body over time without intervention, and those which are non-absorbable and must be manually removed if they are not left indefinitely. Absorbable suture material from purified sheep gut sub-mucous fibrous tissue (mostly collagen) monofilament, brown and beige: 6/0-4: 1-8: Antibacterial Sutures Antibacterial Absorbable Surgical Sutures . A similar suture material is made from polyglycolic acid and coated with polycaprolate (Dexon II). P4HB is a natural biomaterial produced by numerous microorganisms through a fermentation process based on Tepha patented recombinant DNA technology. The Young’s modulus of oriented P4HB fiber (670 MPa) is significantly lower than that of other monofilament sutures like Maxon (2930 MPa), PDSII (1380 MPa), and Biosyn (1000 MPa). When compared with plain or chromic catgut, PGA is much less reactive and is experimentally better able to resist infection from contaminating bacteria.1 PGA has excellent knot security and maintains at least 50% of its tensile strength for 25 days.2 The main drawback of PGA is that it has a high friction coefficient and “binds and snags” when wet. The half-life has become the established criterion for distinguishing between absorbable suture materials. P4HB appears to degrade more slowly than PGA, but faster than PLLA, polycaprolactone (PCL), and other polyhydroxyalkanoates like poly-3-hydroxybutyrate (P3HB) in a subcutaneous environment (Table 11.3). In addition, the molecular weight of the polymer can be controlled by controlling the enzymes in the engineered pathway, providing P4HB molecular weight up to approximately one million with polydispersity of 2–3 (Martin and Williams, 2003).

A gradual reduction in strength is optimal for wound closure and healing as it allows a wound the time to accommodate changes as they occur. Comparisons of properties of P4HB with other synthetic absorbable aliphatic polyesters. The physical structure of nonabsorbable sutures has been shown to be more important in inducing wound infection than the chemical constituents (including the coating materials). Finally the fibre proved rapidly soluble (several hours immersion) in strong caustic soda of pH 14, showing that alkaline conditions were needed for hydrolysis. 1 South American Indians essentially created the first surgical “stapler” by using the heads of pincher ants to close wounds. For example, Blomstedt and Osterberg (1978) observed that surgical infection rates were higher for multifilament sutures due to high capillary capacity than for noncapillary monofilament sutures. The crystallinity is lower than pure glycolic acid, but amorphous zones are needed to enhance breakdown by absorbing body fluids. Compared to Vicryl Rapide in a subcuticular closure, monocryl resulted in significantly smaller, less reactive scars, and a reduced tendency to produce hypertrophic scar formation.34 It is recommended for general soft tissue approximation, including subcutaneous closures. Below is a graphical representation of the comparison between various absorbable sutures on properties such as tensile strength of the sutures, the period within which suture fully absorbs in the body, ease of knotting / knot security and tissue friendliness of each absorbable suture material. The anterior outer row is the last completed. The outer posterior row is placed first (Figure 177-1).
