Tissue adhesives are common adjuncts in surgical practice. Fibrin sealants are the most prevalent adhesives today. Recently, new adhesives have been approved for use in the United States, including cyanoacrylates, albumin-based compounds, collagen-based compounds, glutaraldehyde glues, and hydrogels. This review summarizes all the available tissue adhesives, focusing on their current and prospective indications in the clinical forum.
Tissue adhesives have been available and in use for more than 40 years. They have, however, never been popular for ossiculoplasty because of the reported excessive inflammatory reaction and ototoxicity. The authors present a case of ossicular disruption successfully repaired with tissue adhesive and review the literature.
Surgical tissue adhesives could simplify complex surgical procedures by stabilizing tissue surfaces through hemostasis, sealing wounds, and fixating tissue in areas inaccessible to suture placement. The most common surgical tissue adhesives available to the surgeon include the cyanoacrylate derivatives and the fibrin tissue adhesives. Butyl-2 cyanoacrylate (Histoacryl) is a cyanoacrylate derivative that is frequently used in Canada and Europe. This adhesive has excellent binding strength for skin closure; however, subcutaneous implantation can result in inflammation and foreign body giant cell reaction. Fibrin tissue adhesives use a fibrin clot as the binding moiety and vary in adhesive strength depending on the fibrinogen concentration of the preparation. Autologous fibrin tissue adhesives are prepared using one of several different methods, which vary in fibrinogen yield and concentration. The currently available autologous fibrin tissue adhesives demonstrate good hemostatic properties with relatively low binding strengths. This article reviews the status of cyanoacrylate adhesives and the preparation, efficacy, and clinical applications of the fibrin tissue adhesives.
Twenty concentrates were produced of the blood from voluntary healthy donors by a method for producing autologous tissue adhesive. Their adhesive strength were tested by means of Thermo-fleece-specimens. A review was elaborated about the kinetics and the testing of the fibrin fixation. Methodical faults were found out. Possible ways for improving autologous adhesive variants and for producing homologue tissue adhesive are shown.
Postoperative tissue adhesion causes retarded wound healing and the need for reoperation; it can even be life threatening. In this report, the authors present prototype materials and performance of newly developed tissue adhesion prevention technology based on photocurable polysaccharides. Polysaccharides used were hyaluronic acid and chondroitin sulfate, both of which were partially derived with photoreactive groups such as cinnamoyl, coumarin, and thymine. Photoreactive hyaluronic acids with low degrees of derivatization were soluble in water. Films of cinnamated hyaluronic acid or an aqueous solution of cinnamated chondroitin sulfate were photocured by ultraviolet irradiation, resulting in water adsorbable films or water swollen gels, respectively. Gelation was due to intermolecular dimerization between cinnamoyl groups. The authors provide two potentially applicable examples: 1) a photocured, water swollen hydrogel film, and 2) a photocurable chondroitin sulfate buffer solution. The authors used hydrogel films to cover the peritoneum after mechanically injuring its surface. Histologic examination showed neither tissue nor cell adhesion, and only a minimal inflammatory response. When tissues were coated with a photocurable chondroitin sulfate solution, the viscous solution was converted to a hydrogel upon ultraviolet irradiation, resulting in in situ tissue covering. Although an optimal molecular design has not yet been found, unique features of mucopolysaccharides (e.g., high water uptake; biodegradability and bioresorbability; and nontoxicity of photodimerizable groups) may result in the development of photoinduced tissue adhesion prevention technology.
Different tissue adhesives including an own fibrin adhesive on the base of the human plasma fraction Cohn I were investigated in relation to their adhesive strength tension. These investigations were carried out on lyophilised skin grafts in vitro. The adhesive strengths were equal in case of the Cohn I adhesive, the Tissucol-Kit and also with Beriplast. These investigations will contribute to optimize an adhesive system.
Cyanoacrylate tissue adhesive (CTA) is very useful for emergency treatment of corneal perforations. Lack of Food and Drug Administration approval as well as concerns about toxicity from the application of large amounts of glue, however, have limited its use. It is difficult to apply a sufficiently small amount of glue or to achieve a water tight seal using published techniques of glue application. We have found a commercially available micropipette (used in dental work) to be more effective than other methods of CTA application. With this apparatus, precise and accurate placement of minimal amounts of CTA at the slit lamp is consistently possible.

Surgical closure of a bronchopleural fistula following right pneumonectomy for squamous cell carcinoma was achieved with monomeric n-butyl-2-cyanoacrylate. Previous attempts at closure by conservative and endoscopic means were unsuccessful. Tissue adhesives are useful in the surgical or endoscopic management of bronchopleural fistula.

Bucrylate tissue adhesive has been found to be effective in achieving closure of surgically created bronchopleural fistulas in dogs. Success was obtained with both endoscopic and direct application. Clinical application of this method in one patient was successful [unpublished observations]. We believe that the speed, low risk, and cost-effectiveness of this approach justifies its further use in these difficult situations.

Poly(N-isopropylacrylamide)-grafted hyaluronan (PNIPAM-HA) and PNIPAM-grafted gelatin (PNIPAM-gelatin), which exhibit sol-to-gel transformation at physiological temperature, were applied as control of tissue adhesions: tissue adhesion prevention material and hemostatic aid, respectively. The rat cecum, which was abraded using surgical gauze, was coated with PNIPAM-HA-containing PBS (concentration: 0.5 w/v%). The coated solution was immediately converted to an opaque precipitate at body temperature, which weakly adhered to and covered the injured rat cecum. One week after coating, tissue adhesion between the PNIPAM-HA-treated cecum and adjacent tissues was significantly reduced as compared with that between non-treated tissue and adjacent tissues. On the other hand, the coating of bleeding spots of a canine liver with PNIPAM-gelatin-containing PBS (concentration: 20 w/v%) resulted in spontaneous gel formation on the tissues and subsequently suppressed bleeding. Although these thermoresponsive tissue adhesion prevention and hemostatic materials are still prototypes at this time, both thermoresponsive biomacromolecules bioconjugated with PNIPAM, PNIPAM-HA and PNIPAM-gelatin, may serve as a tissue adhesion prevention material and hemostatic aid, respectively.
BACKGROUND: Tissue adhesives have been used for many years to close simple lacerations as an alternative to standard wound closure (sutures, staples, adhesive strips). They offer many potential advantages over standard wound closure, including ease of use, decrease in pain and time to apply, as well as not requiring a follow-up visit for removal. Many studies have compared tissue adhesives and standard wound closure to determine the cosmetic outcome as well as these other secondary outcomes in their respective study populations. However, due to the wide variation in study parameters, there are no generalisable, definitive answers about the effectiveness of tissue adhesives. No study has been adequately powered to assess differences in complications, which are rare. OBJECTIVES: To summarize the best available evidence for the effect of tissue adhesives in the management of traumatic lacerations in children and adults. SEARCH STRATEGY: We searched the Cochrane Controlled Trials Register (CD ROM 2001 Issue 4), the Cochrane Wounds Group Specialized Trials Register (Nov 2001), MEDLINE (1966 to Oct 1, 2001), and EMBASE (1988 to Sept 1, 2001) for relevant randomised controlled trials (RCTs). We also searched the citations of selected studies, and we contacted relevant authors and manufacturers of tissue adhesives to inquire about other published and unpublished trials. SELECTION CRITERIA: We included RCTs comparing tissue adhesives versus standard wound closure or tissue adhesive versus tissue adhesive for acute, linear, low tension, traumatic lacerations in an emergency or primary care setting. Trials evaluating tissue adhesives for surgical incisions or other types of wounds were not considered. DATA COLLECTION AND ANALYSIS: Data from eligible studies were extracted by one reviewer and checked for accuracy by a second reviewer. Two reviewers independently assessed masked copies for quality. Outcomes of cosmesis (subgroups of age, wound location and need for deep sutures), pain, procedure time, ease of use and complications were analysed separately for two comparisons: 1) tissue adhesive versus standard wound care; and 2) tissue adhesive versus tissue adhesive. MAIN RESULTS: Eight studies compared a tissue adhesive with standard wound care. No significant difference was found for cosmesis at any of the time points examined, using either Cosmetic Visual Analogue Scale (CVAS) or Wound Evaluation Score (WES). Data were only available for subgroup analysis for age; no significant differences were found. Pain scores (Parent VAS WMD -15.7 mm; 95% CI -21.9, -9.5) and procedure time (WMD -5.6 minutes; 95% CI -8.2, -3.1) significantly favoured tissue adhesives. No studies reported on ease of use. Small but statistically significant risk differences were found for dehiscence (favouring standard wound care NNH 25 95% CI 14, 100) and erythema (favouring tissue adhesive NNH 8 95% CI 4, 100). Other complications were not significantly different between treatment groups. Only one study was identified that compared two tissue adhesives (butylcyanoacrylate (Histoacryl TM) versus octylcyanoacrylate (Dermabond TM)) for pediatric facial lacerations. No significant difference was found for cosmesis using CVAS at 1-3 months, or using WES at 5-14 days and 1-3 months. Similarly, no significant difference was found in pain, procedure time or complications. Results for ease of use were incomplete as reported. REVIEWER'S CONCLUSIONS: Tissue adhesives are an acceptable alternative to standard wound closure for repairing simple traumatic lacerations. There is no significant difference in cosmetic outcome between tissue adhesives and standard wound closure, or between different tissue adhesives. They offer the benefit of decreased procedure time and less pain, compared to standard wound closure. A small but statistically significant increased rate of dehiscence with tissue adhesives must be considered when choosing the closure method (NNH 25).
