2-Octyl cyanoacrylate tissue adhesive is increasingly being used for closure of traumatic lacerations. Data regarding the strength of incisions closed with 2-octyl cyanoacrylate are limited. We compared the strength of disruption of closure with glue with that of more conventional methods of wound closure. Segments of fresh porcine skin measuring 3.5 x 10 cm were approximated by one of four methods: 1) 2-octyl cyanoacrylate glue, 2) surgical staples, 3) 0.5 inch Steri-Strips, and 4) interrupted 4–0 poliglecaprone 25 sutures in a subcuticular fashion. Fifteen specimens were used to test each type of closure. The strength of closure was tested on an Instron 4502 tensionometer. The peak force required for disruption of the closure was recorded and the strength of the closure was compared. Staples provided the strongest closure. Skin glue proved superior to Steri-Strips but inferior to stapled closure. The difference between skin glue and suture closure was not statistically significant ( P = 0.12). Patterns of failure differed between the groups. Skin glue failed because of disruption of the skin-glue interface. 2-Octyl cyanoacrylate glue provides a wound closure that is similar to closure with an interrupted subcuticular absorbable suture. This study validates the clinical use of skin glue for closure of surgical incisions. The technique should be used with caution in areas of the body that are subject to tension.
2-Octylcyanoacrylate tissue adhesive (Dermabond™, Ethicon, Inc, Somerville, NJ) is being used successfully for closure of minor lacerations. To date, however, there have been no studies evaluating its use in the operating room for surgical incisions. We conducted a prospective randomized trial to compare the closure of inguinal herniorrhaphy incisions using 2-octylcyanoacrylate tissue adhesive (Dermabond) with closures using 4–0 Monocryl (Ethicon, Inc) in a running subcuticular closure. A total of 46 incisions were randomized at the time of closure. Of these incisions 24 were randomized to Dermabond closure (TA) and 22 were randomized to subcuticular closure (SC). Performance measures included: time for closure, wound complications, and cosmesis. Cosmesis was evaluated by blinded evaluation of photographs of the incisions taken 4 weeks after surgery. Closure times for the TA group were faster than in the SC group (mean of 155 vs 286 seconds; P < 0.001). Wound complications were higher in the TA group ( P = 0.045). Cosmesis was also felt to be better in the SC group with a score of 4.2 versus 3.88, but this did not reach statistical significance. Although the use of Dermabond did result in faster wound cultures it also resulted in an increase in wound complications. The difference in mean cosmetic score for each group was not statistically significant but trended toward better scores in the SC group. Based on these findings we do not feel Dermabond is an acceptable alternative to subcuticular suture closure in inguinal herniorrhaphy incisions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
