Comparing wound closure using tissue glue versus subcuticular suture for pediatric surgical incisions: a prospective, randomised trial

Abstract

Tissue adhesives have gained favour for quicker and painless closure of lacerations. To compare the tissue adhesive 2-octylcyanoacrylate with our current standard subcuticular suture for closure of surgical incisions in children, looking at outcome measures of time efficiency, cosmesis, and wound complications, a prospective, randomised, controlled trial was conducted at our institution's ambulatory surgery centre. All healthy patients undergoing unilateral or bilateral herniotomies were recruited prospectively with informed consent and randomly allocated to suture or glue. The exclusion criteria were neonates or children with allergy to tissue glue. Time of wound closure was measured from the subcutaneous layer to application of the dressing. An independent, blinded observer assessed cosmesis at 2 to 3 weeks using a validated wound scale ranging from worst (0) to best (6). Parent satisfaction with wound appearance was recorded on a 100-mm visual analogue scale (VAS). A total of 59 patients were recruited into the study with 26 in the glue group and 33 in the suture group. There was no difference in mean time of closure (glue 181 +/- 62 s vs suture 161 +/- 45 s, P = 0.18). Two patients in each group had a suboptimal Hollander wound score of 5 (7.7% glue, 6.1% suture). There was also no difference in parent satisfaction (VAS: glue 78 +/- 19 mm vs suture 81 +/- 15 mm, P = 0.68). No patient reported any rash, wound infection, or dehiscence. Tissue glue is easy to use with no complications and has equivalent cosmetic results, but is not faster than a subcuticular suture.
