Abstract
BACKGROUND Triclosan-coated vicryl plus suture (Ethicon, Inc.) was developed to reduce microbial colonisation during surgical procedures. However, its effect on wound healing and surgical site infections remain unclear after hip and knee arthro-plasty surgery.
AIM To determine the effect of triclosan-coated sutures (TCS) vs non-coated sutures on wound healing, following primary hip and knee arthroplasties.
METHODS A single-centred, double-blind randomised controlled trial (RCT) was undertaken. We randomly allocated patients to receive either the triclosan-coated sutures (TCS vicryl plus) or non-coated sutures (NCS vicryl) during the closure of unilateral primary hip and knee arthroplasties. We utilised the ASEPSIS wound scoring system to evaluate wound healing for the first 6 weeks post-operatively.
RESULTS One hundred and fifty patients undergoing primary total hip or knee arthroplasty over a one-year period were included. Eighty-one were randomised to the TCS group and 69 to the NCS group. Despite no statistically significant difference in the ASEPSIS scores among the study groups (P = 0.75), sensitivity analysis using the Mann Whitney test (P = 0.036) as well as assessment of the wound complications at 6 weeks follow up, demonstrated significantly higher wound complication rates in the TCS group (8 vs 1, P = 0.03).
CONCLUSION No clear advantage was demonstrated for using the TCS. However, larger multi-centred RCTs are required to validate their use in hip and knee arthroplasty surgery.

J Surg Res 2016; 201:105-17. [PMID: 26850191 DOI: 10.1016/j.jss.2015.10.015] [Citation(s) in RCA: 38] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2015] [Revised: 09/19/2015] [Accepted: 10/07/2015] [Indexed: 01/27/2023]
Abstract
BACKGROUND Surgical site infection (SSI) is the third most frequent type of nosocomial infections. Triclosan-coated sutures are often used to reduce the risk of SSI, but studies examining this have given conflicting results. Therefore, this meta-analysis was performed to assess the efficacy of triclosan-coated sutures for reducing risk of SSI in adults. METHODS PubMed, EMBASE, Google Scholar, and ClinicalTrials.gov were searched to identify randomized clinical trials evaluating triclosan-coated sutures for preventing SSI on patients 18 y or older. RESULTS Thirteen randomized clinical trials involving 5256 participants were included. Triclosan-coated sutures were associated with lower risk of SSI than uncoated sutures across all surgeries (risk ratio [RR] 0.76, 95% confidence interval [CI] 0.65-0.88, P < 0.001). Similar proportions of patients experienced wound dehiscence with either type of suture (RR 0.97, 95% CI 0.49-1.89, P = 0.92). Subgroup analysis showed lower risk of SSI with triclosan-coated sutures in abdominal surgeries (RR 0.70, 95% CI 0.50-0.99, P = 0.04) and group with prophylactic antibiotic (RR 0.79, 95% CI 0.63-0.99, P = 0.04). However, such risk reduction was not observed in cardiac surgeries, breast surgeries, or group without prophylactic antibiotic. CONCLUSIONS Triclosan-coated sutures can decrease the incidence of SSI in abdominal surgeries and might not interfere with wound healing process. Nevertheless, further studies are needed to examine whether triclosan-coated sutures are effective at preventing SSI in non-abdominal surgeries and to further study the interaction of antibiotic prophylaxis with triclosan-coated sutures.

Abstract
Acute and chronic wounds represent a very common health problem in the entire world. The dermal wounds are colonized by aerobic and anaerobic bacterial and fungal strains, most of them belonging to the resident microbiota of the surrounding skin, oral cavity and gut, or from the external environment, forming polymicrobial communities called biofilms, which are prevalent especially in chronic wounds. A better understanding of the precise mechanisms by which microbial biofilms delay repair processes together with optimizing methods for biofilm detection and prevention may enhance opportunities for chronic wounds healing. The purpose of this minireview is to assess the role of polymicrobial biofilms in the occurrence and evolution of wound infections, as well as the current and future preventive and therapeutic strategies used for the management of polymicrobial wound infections.

Abstract
OBJECTIVE The aim of this study was to assess if an antiseptic pomade could reduce the bacterial colonization on multifilament sutures. STUDY DESIGN A randomized clinical trial was conducted with 40 volunteer patients of both sexes aged 18-70, randomly separated into experimental (n = 20) and control (n = 20) groups. The experimental group received pomade-coated sutures (iodoform + calendula) and the control group uncoated sutures. Two millimeters of the suture was harvested from each patient from the 1st to the 15th postoperative day. The bacteria that had adhered to them were cultured. The number of colony-forming units per milliliter (CFU/mL) was determined and the groups were compared using the Mann-Whitney statistical test (P < .05). RESULTS The experimental group showed a significant reduction in bacterial growth compared with the control group (P = .002). CONCLUSIONS In this experimental model, the antiseptic pomade was effective in reducing bacterial colonization on silk braided sutures.

Abstract
Background Wound infection affects a considerable portion of patients after abdominal operations, increasing health care costs and postoperative morbidity and affecting quality of life. Antibacterial coating has been suggested as an effective measure to decrease postoperative wound infections after laparotomies. The INLINE metaanalysis has recently shown the superiority of a slowly absorbable continuous suture for abdominal closure; with PDS plus® such a suture has now been made available with triclosan antibacterial coating. Methods/Design The PROUD trial is designed as a randomised, controlled, observer, surgeon and patient blinded multicenter superiority trial with two parallel groups and a primary endpoint of wound infection during 30 days after surgery. The intervention group will receive triclosan coated polydioxanone sutures, whereas the control group will receive the standard polydioxanone sutures; abdominal closure will otherwise be standardized in both groups. Statistical analysis is based on intention-to-treat population via binary logistic regression analysis, the total sample size of n = 750 is sufficient to ensure alpha = 5% and power = 80%, an interim analysis will be carried out after data of 375 patients are available. Discussion The PROUD trial will yield robust data to determine the effectiveness of antibacterial coating in one of the standard sutures for abdominal closure and potentially lead to amendment of current guidelines. The exploration of clinically objective parameters as well as quality of life holds immediate relevance for clinical management and the pragmatic trial design ensures high external validity. Trial Registration The trial protocol has been registered with the German Clinical Trials Register (DRKS00000390).

Abstract
BACKGROUND Incisional hernia remains among the most common complications after midline incision of the abdominal wall. The role of the suture material used for abdominal wall closure remains controversial. To decrease bacterial adherence to surgical sutures, braided suture materials with antibacterial activity (Vicryl plus, Ethicon, Inc) were developed. This is the first study to analyze long-term results using an antibacterial-braided suture material for abdominal wall closure in a large clinical trial. METHODS To analyze the effects of Triclosan-coated suture material (Vicryl plus) on the development of incisional hernia, we performed a 36-month follow-up of 1,018 patients who had a primary midline incision for elective abdominal surgery. In the first time period, a PDS II loop suture was used. In the second observation period, we used Vicryl plus. All variables were recorded prospectively in a database. The primary outcome was the number of incisional hernias. Risk factors for the development of incisional hernias were collected prospectively to compare the 2 groups. RESULTS The overall incisional hernia rate in the 36-month follow-up period was 14.6%. Analyzing the influence of the suture material used on the development of incisional hernia, we did not find differences between the 2 groups (PDS II, 14%; Vicryl plus, 15.2%). In the multivariate analysis of possible factors in the study population, only body mass index (BMI) showed a significant influence on the development of incisional hernias. Despite the incidence of wound infections being less in the Vicryl plus group (6.1% vs 11.9%; P < .05), there were no difference in incidence of incisional hernia between the 2 groups. CONCLUSION Fast absorbable sutures with antibacterial coating (Tricosan) do not increase the hernia rate after midline abdominal incision compared with slowly absorbable sutures, when wound infection rates are decreased by coating the fast absorbable suture with Triclosan. The development of incisional hernia is significantly increasing in patients with a BMI >30 kg/m(2).

Abstract
This report is based on a Hygienist Panel Meeting held at St Anne's Manor, Wokingham on 24-25 June 2009. The panel agreed that greater use should be made of antiseptics to reduce reliance on antibiotics with their associated risk of antibiotic resistance. When choosing an antiseptic for clinical use, the Biocompatibility Index, which considers both the microbiocidal activity and any cytotoxic effects of an antiseptic agent, was considered to be a useful tool. The need for longer and more proactive post-discharge surveillance of surgical patients was also agreed to be a priority, especially given the current growth of day-case surgery. The introduction of surgical safety checklists, such as the World Health Organization's Safe Surgery Saves Lives initiative, is a useful contribution to improving safety and prevention of SSIs and should be used universally. Considering sutures as 'implants', with a hard or non-shedding surface to which micro-organisms can form biofilm and cause surgical site infections, was felt to be a useful concept.

Abstract
BACKGROUND Poor wound healing and the development of infection in incisional wounds continue to be among the most common complications of open abdominal surgery. Various bacteria may contaminate not only the tissue in the operative wound, but also the actual suture material. To prevent the contamination of suture material in surgical wounds, triclosan-coated polyglactin 910 suture materials with antibacterial activity (Vicryl plus) was developed. The aim of this study was to ascertain if the use of Vicryl plus reduced the number of wound infections after midline laparotomy comparing to polydioxanon suture (PDS II). METHODS We performed 2,088 operations in our department between October 2004 and September 2006 via midline incision. In the first time period (TP1), a PDS II loop suture was used. In the second time period (TP2), we used Vicryl plus. All variables were recorded prospectively in a database. The primary outcome was the number of wound infections. Risk factors for poor wound healing were collected prospectively to compare the 2 groups. RESULTS Using a PDS loop suture for abdominal wall closure in TP1, 10.8% of patients with wound infections were detected. The number of patients with wound infections decreased in TP2 using Vicryl plus for abdominal wall closure to 4.9% (P < .001) despite no other changes in protocols of patient care. Other risk factors for the development of site infections were comparable in the 2 groups. CONCLUSION The use of antibiotic-coated loop suture for abdominal wall closure can decrease the number wound infections after abdominal surgery.

Abstract
BACKGROUND Surgical site infections are associated with severe morbidity and mortality. The role of surgical sutures in the etiology of surgical site infection has been the objective of discussion for decades. This study used a standardized in vitro microbiologic model to assess bacterial adherence and the antibacterial activity of a triclosan-coated polyglactin 910 (braided) suture against selected Gram-positive and Gram-negative clinical isolates that may infect surgical wounds. STUDY DESIGN Standardized cultures (2.0 log(10) colony forming units/mL and 5.0 log(10) colony forming units/mL of three clinical strains, Staphyllococcus aureus (methicillin-resistant S aureus [MRSA]), S epidermidis (biofilm-positive) and Escherichia coli (extended-spectrum beta-lactamase [ESBL]-producer) were inoculated to triclosan-coated and noncoated polyglactin 910 sutures to evaluate comparative adherence of bacterial isolates to the antibacterial coated and noncoated surgical sutures; to assess the impact of serum proteins (bovine serum albumin) on antibacterial activity of triclosan-coated suture; and to document the duration of antibacterial activity of the triclosan-coated material. Selected suture samples were prepared for scanning electron microscopy to demonstrate bacterial adherence. RESULTS Substantial (p < 0.01) reductions in both Gram-positive and Gram-negative bacterial adherence were observed on triclosan-coated sutures compared with noncoated material. Pretreatment of surgical sutures with 20% BSA did not diminish antibacterial activity of the triclosan-coated braided device compared with noncoated suture (p < 0.01), and antibacterial activity was documented to persist for at least 96 hours compared with controls (p < 0.01). CONCLUSIONS The in vitro model demonstrated a considerable reduction (p < 0.01) in Gram-positive and Gram-negative bacterial adherence to a triclosan-coated braided suture, which was associated with decreased microbial viability (p < 0.001). Because bacterial contamination of suture material within a surgical wound may increase the virulence of a surgical site infection, treating the suture with triclosan provides an effective strategy for reducing perioperative surgical morbidity.

Abstract
Multifilament nylon fibers were made antibacterial by dopping with iodine. Nylon fibers were immersed in acetone solution of iodine for 48 hours at room temperature for dopping of iodine. It was observed that iodine uptake by the nylon fibers increased with the increase in concentration of iodine in the solution. Antibacterial activity of these iodine dopped samples was evaluated by measuring the zone of inhibition. The bacterial species used for this study were Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus and Klebsiella pneumoniae. Iodine dopped fibers exhibited good antibacterial activity against these bacterial species. Release of iodine in distilled water is sustained for about 30 days. Antibacterial activity of the fibers decreases with the release of iodine in water. Ultra-violet and visible spectroscopic studies showed that tri-iodide ions were released from the dopped samples in the aqueous medium. These I3- ions might be responsible for the observed antibacterial activity. Fiber shrinks on iodine dopping leading to increase in the denier of the fiber. However effect of iodine dopping on the breaking load of fibers is not significant.

A new type of braided nylon thread with a silver compound coating was made for the purpose of designing a biocidal suture material. The study used standard bacterial culture techniques to evaluate the antibacterial property of the new Ag-coated nylon thread. Seven types of bacterial species were tested; S. aureus, E. coli, P. aeruginosa, K. pneumoniae, S. dysenteriae, S. maruslens, and P. mirabilis. The commercial size 2/0 Nurolon suture from Ethicon served as the control. A weak direct current ranging from 0.4-400 microA was applied to the specimens to examine whether the biocidal property of silver could be enhanced by current. The antibacterial property was evaluated by the width and sterility of the clear zone in the bacterial culture plates. It was found that the new nylon thread exhibited very good to moderate bactericidal property toward these seven bacterial species. P. aeruginosa was the most sensitive species, while P. mirabilis was the least sensitive one. Application of direct current through the Ag-coated specimens positively enhanced their antibacterial property and the degree of enhancement depended on the direct current level. The material also exhibited an antibacterial property toward well-established bacterial colonies, but the effect was less strong than the case when direct current was applied simultaneously with incubation. Silver ions released from the coated nylon thread were responsible for the observed antibacterial property; and the application of a weak direct current to the material enhanced this effect. A preliminary biocompatibility study of this new material in rat gluteal muscle indicated that the new material caused less inflammatory reaction than the control Nurolon suture up to 60 days after implantation.
