Aesthetic outcome of intermediate closure versus intermediate closure followed by 2-octyl cyanoacrylate: A randomized evaluator-blinded split-wound comparative effectiveness trial

BACKGROUND

Dermatologic surgeons are increasingly using surgical adhesives in their practice. Studies comparing sutured wounds to those that utilize a combination of suturing and skin adhesive have not been previously conducted.

OBJECTIVE

To compare the cosmetic outcome and patient wound care satisfaction of an intermediate suture closure with an intermediate suture closure followed by the application of 2-octyl cyanoacrylate (2-OCA).

METHODS

Fifty patients were enrolled in a randomized, evaluator-blinded, split-scar study. Following intermediate sutured closure of a surgical defect, one side of the wound was randomized to receive an additional application of 2-OCA. After 3 months, the scar was assessed using the POSAS tool and patients reported wound care preferences.

RESULTS

As the primary outcome measure, the mean sum of observer POSAS was 12.80 for sutured closure alone versus 12.40 for sutured closures followed by 2-OCA (P = .49).

LIMITATIONS

Single-center study of a relatively homogenous population.

CONCLUSION

Although there were no significant differences in scar cosmesis, both patients and observers tended to prefer the side with an additional application of 2-OCA in most POSAS components, in overall opinion, and in patient wound care satisfaction. Dermatologic surgeons may add this to their practice without sacrificing scar outcomes or patient satisfaction.

Comparison of 2-octyl cyanoacrylate with polyester mesh with standard suture and staples in total knee and hip arthroplasty

OBJECTIVE

The use of 2-octyl cyanoacrylate with polyester mesh (OCA-M) has become common in total hip and knee arthroplasty (THA, TKA). We aimed to compare the safety and cosmetic outcomes between OCA-M and standard suture techniques and staples, and determine whether OCA-M can safely be used for TKA.

METHOD

Inclusion criteria were patients who underwent THA or TKA from January 2010 to October 2011 (Suture group), November 2011 to August 2013 (Staple group), March 2017 to September 2018 (OCA-M group). Exclusion criteria was loss of imaging data. Complications during hospitalisation (early complication) and after discharge (late complication) were compared in groups. Plastic and orthopaedic surgeons performed cosmetic evaluations with the modified Vancouver Scar Scale (VSS) and Likert scale at three and six months postoperatively and compared in groups.

RESULTS

A total of 249 arthroplasties (suture group=88 patients; staple group=94 patients; OCA-M group=67 patients) were included in the study. The OCA-M group had a significantly lower early complication rate than the suture group (p=0.015). For THA, the OCA-M group had a significantly lower total complication rate than the suture group (p=0.048). For TKA, there was no significant difference among the three groups. The complication rate in the OCA-M group showed no significant difference between THA/TKA. With regards to the VSS, the OCA-M group was significantly better for cosmetic qualities than the suture group (p=<0.001, p=0.021 at three and six months, respectively). For the Likert scale, the OCA-M group was also significantly better for cosmetic qualities than the suture group and staple group (suture-OCA-M, p=0.003 (three months), p=<0.001 (six months); staple-OCA-M, p=0.027 (three months)).

CONCLUSION

In this study, the OCA-M complication rate was low compared to suturing and similar to stapling. Moreover, better cosmetic outcomes were achieved compared to suturing and stapling.

Antimicrobial Activity and Cytotoxicity of Prepolymer Allyl 2-cyanoacrylate and 2-Octyl Cyanoacrylate Mixture Adhesives for Topical Wound Closure

The development of a new skin adhesive that can be used inside and outside the body, which prevents infection and has fewer scars and less side effects, is currently attracting attention from the scientific community. To improve biocompatibility, prepolymer allyl 2-cyanoacrylate (PAC) and 2-octyl cyanoacrylate (OC) were mixed in various proportions and tested for their therapeutic potential as skin adhesives. A series of skin adhesive samples prepared by mixing PAC, OC, and additives with % (w/w) ratios of 100:0:0, 0:100:0, 70:0:30, 40:30:30, and 30:40:30 were tested to determine their antimicrobial activity, cell cytotoxicity, and formaldehyde release. The additives include myristic acid and dibutyl sebacate as plasticizers and butylated hydroxyanisole as an antioxidant. It was observed that the samples containing 70% PAC (PAC7) or 40% PAC (PAC4) with 30% additives had the highest antimicrobial activities against various microbial cells and no cytotoxicity regarding in vitro fibroblast cell growth. In addition, these formulations of adhesive samples released formaldehyde within the levels permitted for medical devices. Taken together, the mixture of PAC and OC as a topical skin adhesive for wound closure was found to be biocompatible, mechanically stable and safe, as well as effective for wound healing.

Wound closure with a mesh and liquid tissue adhesive (Dermabond Prineo) system in pediatric spine surgery: a prospective single-center cohort study incorporating parent-reported outcome measures

OBJECTIVE

Wound healing can be challenging in children undergoing spine surgery for neurological conditions due to a high risk of cerebrospinal fluid (CSF) leakage and wound infection. In adults, use of the Dermabond Prineo (DP) skin closure system, which consists of both tissue adhesive glue and a self-adhesive mesh, for wound closure of medium-length surgical incisions has been reported. The aim of this study was to investigate the efficiency and cosmetic outcome of DP for wound closure in extra- and intradural pediatric neurological spine surgery.

METHODS

In this prospective cohort study, 47 children underwent 50 spine procedures using DP for wound closure between 2018 and 2022 at a single institution. Patient demographic and surgical data were collected. The primary outcome was revision surgery for wound healing disorders, while secondary outcomes were infections, minor wound healing disorders, and both physician and parental satisfaction (parent-reported outcome measures [PROMs]) at last follow-up.

RESULTS

Among 50 spinal (45 intra- and 5 extradural) interventions, 1 patient (2%) underwent revision surgery for a cutaneous CSF fistula and pseudomeningocele. Minor wound healing disorders occurred after 16 surgeries, which did not require surgical wound revision and resolved completely. No allergic reactions to DP or surgical site infections within 30 days were observed. The parents and the medical team described wound care as significantly facilitated since wound dressing changes were not needed. Three families (6.4%) encountered difficulties in wound care, and 46 (97.9%) were satisfied with DP. The cosmetic outcome based on PROMs was excellent, with a mean score of 8 (IQR 2) on a scale from 1 to 10. At long-term follow-up, a mean of 11.3 ± 10.7 months after surgery, physicians rated the cosmetic outcome on the visual analog scale (median score 9, IQR 1) and Hollander scale (median score 6, IQR 1). The outcomes were similar among the different pathologies and age groups and did not differ in patients with and without syndromic malformations.

CONCLUSIONS

The application of DP is simple, enables good patient comfort, facilitates both professional and parental wound care, and leads to excellent cosmetic results. DP possibly aids in the reduction of postoperative CSF leakage and infections after pediatric neurological spine surgery.

Outcomes of 2-octyl cyanoacrylate skin adhesives following musculoskeletal oncology surgery: A STROBE-compliant observational study

ABSTRACT

2-octyl cyanoacrylate (2OCA) is a high-viscosity medical-grade tissue adhesive that is routinely used. However, no studies have evaluated its use in musculoskeletal surgery.We enrolled 99 patients who underwent musculoskeletal surgery. 2OCA was chosen for wound closure and was performed by a specific surgeon for all patients. The drying times for the adhesive were recorded, and photographs were obtained intra-operatively. Posttreatment follow-up consisted of queries regarding pain level and recording incisional dehiscence, wound infection, hematoma, and incisional bleeding. Data collection was performed postoperatively at 48 hours, 5 to 10 days, 14 days, and 30 days. Other adverse events were documented.2OCA was applied to 110 incisions in 99 patients, comprising 62 female and 37 male patients. The mean age of patients was 50.41 (±16.83) years; mean incision length was 10.24 (±5.7) cm, and the mean pain score using a visual analogue scale was 2.37 on a postoperative day 7. The mean drying time was 1.81 (±0.59) minutes; 91 (91%) patients reported excellent and superior satisfaction, and the remaining patients reported "good" (6%) and "fair" (2%) satisfaction. The percentages of dehiscence, hematoma and keloid formation were considerably low.In this study, 2OCA was safe for musculoskeletal oncology surgical incisions. The incidence of postoperative adverse events was low. However, some patients develop hematomas. Postoperative pain was low, and patient satisfaction was high. 2OCA can be a practical alternative to traditional suture closure for skin incisions after musculoskeletal surgery.

Economic and clinical outcomes of spinal fusion surgeries with skin closure through skin staples plus waterproof wound dressings versus 2-octyl cyanoacrylate plus polymer mesh tape

BACKGROUND CONTEXT

Spinal fusion surgeries are one of the most common types of operations performed during inpatient stays in the United States. Successful wound closure, including watertight closure at the skin layer, plays in important role in patient outcomes.

PURPOSE

To compare the economic and clinical outcomes of spinal fusion surgeries using one of two sutureless skin closure techniques: skin staples plus waterproof wound dressings (SSWWD) or 2-octyl cyanoacrylate plus polymer mesh tape (2OPMT).

STUDY DESIGN/SETTING

Retrospective study using a multi-hospital database.

PATIENT SAMPLE

Patients undergoing inpatient spinal fusion surgery for a spine disorder between October 1, 2015 and March 31, 2019.

OUTCOME MEASURES

Total costs from the hospital perspective, operating room time (ORT), hospital length of stay (LOS), non-home discharge, infection/wound complications during the 90-day global period (index surgery through 90 days post-discharge), and 30/60/90-day all-cause readmissions.

METHODS

Outcomes were compared between study groups using nearest neighbor propensity score matching with exact matching on 45 primary procedure/diagnosis code groupings and generalized estimating equations to account for hospital-level clustering. This study was sponsored by Ethicon, Inc., a Johnson & Johnson company; the authors are employees or consultants of Johnson & Johnson.

RESULTS

A total of 11,991 patients met the study criteria (2OPMT=5,961; SSWWD=6,030), of which 3,602 were included in each post-match study comparison group (total=7,204). As compared with the SSWWD group, the 2OPMT group had statistically significant lower median ORT (240 vs. 270 minutes; p=0.002), mean LOS (3.35 [SD=2.6] vs. 3.86 [SD=2.8] days, p=0.031), risks of non-home discharge status (17.63% vs. 23.10%, p=0.035), overall infections/wound complications (1.37% vs. 2.48%, p=0.015), and surgical site infection (1.11% vs. 2.07%, p=0.023). Differences between the study groups in total hospital costs, all-cause readmissions, and other sub-components of the infection/wound complication composite outcome were statistically insignificant (p>0.05).

CONCLUSIONS

In this retrospective observational study of patients undergoing elective inpatient spinal fusion surgery, the use of 2OPMT for skin closure was associated with significantly lower ORT, LOS, non-home discharge, and 90-day rates of infections/wound complications as compared with SSWWD.

Allergic contact dermatitis due to the liquid skin adhesive Dermabond® predominantly occurs after the first exposure

BACKGROUND

The clinical characteristics of patients with allergic contact dermatitis (ACD) due to a skin adhesive containing 2-octyl cyanoacrylate, Dermabond®, have not yet been elucidated.

OBJECTIVE

To investigate the clinical characteristics of patients with ACD caused by Dermabond® application.

METHODS

In this retrospective study, 577 patch tested patients were included. We identified patients with positive patch test results for Dermabond® and evaluated their results concerning (meth)acrylates and ethyl cyanoacrylate adhesive.

RESULTS

Nine patients had positive patch test results to Dermabond®; six had developed secondary generalization.The mean time between Dermabond® application and ACD onset was 34 days (range, 27-44) in six patients with ACD after the first use, whereas, in the other three patients, it was 5.6 days (range, 4-8) after the second use. The time was significantly different between the two groups (P < .01). Positive reactions to ethyl cyanoacrylate adhesive (Aron Alpha) occurred in seven of nine patients, to ethyl cyanoacrylate 10% pet. in four of eight patients tested, and to 2-hydroxyethyl methacrylate in one of eight patients tested.

CONCLUSIONS

Dermabond®-induced ACD is apparently characterized by a high prevalence of primary sensitization at first exposure to Dermabond®, secondary generalization is frequent, and most patients show cross-reactivity to ethyl cyanoacrylate.

Clinical and economic outcomes of cesarean deliveries with skin closure through skin staples plus waterproof wound dressings versus 2-octyl cyanoacrylate plus polymer mesh tape

PURPOSE

To compare clinical and economic outcomes of cesarean deliveries with skin closure through skin staples plus waterproof wound dressings (SSWWD) versus 2-octyl cyanoacrylate plus polymer mesh tape (2OPMT). We hypothesized that cesarean deliveries with skin closure through 2OPMT may be associated with a lower rate of wound complications and infections as compared with skin closure through SSWWD; we also hypothesized that, accordingly, 2OPMT may be associated with lower hospital length of stay (LOS), hospital costs, and all-cause readmissions as compared with SSWWD.

METHODS

Retrospective, observational study using a research database derived from administrative records routinely contributed by hundreds of hospitals in the USA. We queried the database for patients aged 18-49 years who had an in-hospital low transverse cesarean delivery between 1 January, 2012 and 31 March, 2017. Using records of medical supplies used during deliveries, we identified deliveries for which skin closure was performed by either SSWWD (SSWWD group) or 2OPMT (2OPMT group). Our primary study outcome was a composite endpoint of infection/wound complication diagnosis during the hospital stays in which the deliveries were performed. Our secondary outcomes included: length of stay (LOS) and total hospital costs for the hospital stays in which the deliveries were performed, and all-cause readmissions (30/60/90 days post discharge) to the same hospital in which the delivery was performed. We compared outcomes between propensity-score matched groups using regressions accounting for hospital-level clustering and non-Gaussian empirical outcome distributions.

RESULTS

Each group comprised 2133 patients (4266 total patients; mean age = 30.3 years [SD = 4.6]). Compared with the SSWWD group, the 2OPMT group had statistically significant lower rates of complications (infection, 0.7 versus 1.6%, p = .011; wound complication, 0.6 versus 1.3%, p = .036; composite, 0.9 versus 2.0%, p = .002), shorter LOS (mean = 3.5 days [SD = 1.6] versus 3.7 days [SD = 1.8], p = .007), and lower total hospital costs (mean = $8879 [SD = $3157] versus $9313 [SD = $3311], p = .025). Between-group differences for 30/60/90-day all-cause readmissions were statistically insignificant.

CONCLUSIONS

This large observational study is the first of its kind and provides evidence that cesarean delivery skin closure with 2OPMT is associated with lower rates of in-hospital infection and wound complications, lower LOS, lower total hospital costs as compared with SSWWD.

Comparison of 2-Octyl Cyanoacrylate Topical Skin Adhesive and Simple Interrupted Nylon Sutures for Wound Closure in Ankle Fracture Surgery

BACKGROUND

Multiple options are available for closure of incisions in ankle fracture surgery. The aim of our study was to compare postoperative outcomes between conventional simple interrupted nylon sutures and 2-octyl cyanoacrylate as a topical skin adhesive to close the incision after ankle fracture surgery.

METHODS

We retrospectively reviewed the records of 367 consecutive patients (174 simple interrupted nylon suture patients and 193 topical skin adhesive patients) who underwent operative treatment for ankle fracture between 2010 and 2015. Development of wound complications, operative time, Olerud-Molander Ankle Score (OMAS), and patient satisfaction with the wound were compared. The demographics between the 2 groups were not different.

RESULTS

There were no differences in complication rates ( P = .861), OMAS at 3 months or 12 months following surgery ( P = .897 and .646, respectively) between the 2 types of wound closure. Operative time was 9 minutes shorter when topical skin adhesive was used compared to nylon sutures ( P = .003). Patient satisfaction with their wound was significantly higher in the topical skin adhesive group than the nylon skin suture group ( P = .012).

CONCLUSIONS

The use of 2-octyl cyanoacrylate topical skin adhesive for wound closure following ankle fracture surgery was effective, safe, and showed higher patient satisfaction compared to simple interrupted nylon sutures. Although caution should be taken because of the insufficient statistical power of complications, this method was an additional safe option for wound closure in ankle fracture surgery.

LEVEL OF EVIDENCE

Level III, retrospective comparative study.

Friction Blisters on the Hands Treated Successfully Using 2-Octyl Cyanoacrylate: A Case Report

BACKGROUND

Friction blisters on the hand are challenging to treat as conventional dressings are prone to saturation, contamination, and loosening with active hand use and other mechanical stresses. Alternative methods and materials for dressing hand blisters warrant exploration.

CASE SUMMARY

A 48-year-old male surgeon presented with friction blisters over his bilateral thumbs. The patient complained of significant difficulty in keeping his dressings clean and dry, significant pain with hand hygiene, and functional limitations at work. The patient's blisters were dressed with 2-octyl cyanoacrylate (Dermabond; Ethicon US LLC, Somerville, New Jersey), applied directly onto the wound bed. The patient was able to perform his normal duties immediately, without the need for additional intervention. Six days postapplication, the Dermabond sloughed off, revealing an epithelialized surface.

CONCLUSION

Dermabond is a promising agent for dressing unroofed blisters of the hand, as it provides a barrier to moisture and contamination, while allowing the wound to epithelialize, without functional cost.

2-octyl cyanoacrylate versus reintervention for closure of urethrocutaneous fistulae after urethroplasty for hypospadias: a randomized controlled trial

BACKGROUND

Urethrocutaneous fistulae (UCFs) represent one of the most frequent causes of morbidity after urethroplasty. Hypospadias can be repaired using different surgical techniques, but-regardless of technique-the incidence of UCF ranges between 10% and 40%. Surgical repair of UCF remains the treatment of choice, even if some patients need further surgery because of recurrences. Cyanoacrylates have been used as skin suture substitutes, and some evidence suggests a beneficial effect when these adhesives are used as an adjuvant in the management of UCF. Here we describe the results of management of UCF using 2-octyl cyanoacrylate (OCA) compared with surgical repair.

METHODS

A randomized clinical trial conducted from January 2008 to December 2012 included 42 children with UCF complications after urethroplasty for hypospadias. Twenty-one children were assigned to receive OCA as ambulatory patients and 21 were treated surgically. The main outcome variable was closure of the UCF. The estimated costs of both treatments were also calculated, as were absolute risk reduction (ARR), relative risk reduction (RRR) and number needed to treat (NNT) to prevent a surgical intervention.

RESULTS

The mean numbers of UCF were 1.3 in the OCA group (n = 28) and 1.1 in the surgical group (n = 25) with no statistically significant difference. The external orifices measured were 2.96 ± 1.0 mm and 3.8 ± 0.89 mm, respectively (NS). Sixty per cent of the UCFs treated with cyanoacrylate were completely closed and 68% of the surgical group healed completely (NS). More than one reoperation to improve complications was needed in the surgical group (3.5 ± 1.2). The clinical significance of the therapeutic usefulness of OCA was demonstrated by an ARR of 0.08, RRR of 0.25 and NNT of 12 to avoid further surgical treatment. The total costs of adhesive applications and reoperations were $US 14,809.00 and $US 158,538.50, respectively.

CONCLUSIONS

The results showed a similar success rate for both treatments. However, sealant use should be considered before surgical treatment because this is a simple outpatient procedure with a reasonable success rate.

A comparison of 2-octyl cyanoacrylate with nylon for wound closure of knee arthroscopy portals

OBJECTIVE

To compare the cosmetic results, complications and patient satisfaction of 2-octyl cyanoacrylate (Dermabond, Ethicon Inc. Somerville, NJ, USA), a liquid bonding agent, with 3-0 nylon sutures (Ethilon, Ethicon Inc) skin closure in two groups of patients undergoing elective knee arthroscopy at 6 weeks.

METHOD

The retrospective clinical audit recruited patients undergoing knee surgery for the first time between October 2010 and August 2011. The patients were either treated with the liquid bonding agent or nylon sutures. The patients in the bonding agent group were allowed to shower as normal on postoperative day one, while patients in the suture group kept their wounds dry for 2 weeks.

RESULTS

Between the two groups (40 patients per group) there was no difference in the cosmetic outcome (p=0.285), patient satisfaction (p=0.29), pain scores (p=0.44) or wound complication rate (p<0.05). Patient satisfaction was high in both groups. Furthermore, 83.75% of all patients indicated they would prefer the liquid bonding closure over nylon sutures if undergoing the same procedure in the future as they could shower the next day and avoid suture removal.

CONCLUSION

2-octyl cyanoacrylate is safe to use in the short term in knee arthroscopy providing comparable results to nylon suture closure. Allowing patients to shower the next day appears to cause no adverse effects.

Systematic review of cyanoacrylate embolization for refractory gastrointestinal fistulae: a promising therapy

BACKGROUND

Surgical management of gastrointestinal fistulae has been reported to carry a 30-day morbidity rate up to 82% and a mortality rate ranging from 2% to 4.8%; thus nonoperative alternatives are required. The aim of the present study was to assess the current experience on the use of cyanoacrylates in the management of these fistulae.

METHODS

A systematic review was carried out on Medline, Embase, The Cochrane database, Academic Search Complete, MedicLatina, and SciELO for English, Spanish, and Portuguese articles dealing with refractory fistulae by means of cyanoacrylate embolization therapy. Publication dates were restricted from 1969 to present. Outcome parameters were study design, number of participants, etiology of the fistula, approach, material used, success rate, complications, and mortality.

RESULTS

Electronic search yielded a total of 377 articles. After a meticulous screening, only 14 studies dealing with foregut/midgut fistulae and 6 addressing hindgut fistulae were included. All the included articles were prospective and retrospective case series. Cumulative success rate was 81% (range 0% to 100%) and 3 out of 203 patients (1%) developed minor complications.

CONCLUSION

Cyanoacrylate embolization of nearly all types of refractory gastrointestinal fistulae is a feasible and harmless technique. Prospective controlled studies are required to support the available evidence.
