A randomised clinical trial to compare octyl cyanoacrylate with absorbable monofilament sutures for the closure of laparoscopic cholecystectomy port incisions.

Tissue adhesives have gained increasing use as a possible method of wound closure. We compared the use of 2-octyl cyanoacrylate (OCA) or subcuticular suture in incisions sutures for the closure of laparoscopic cholecystectomy port incisions. A prospective randomised controlled trial was performed. Patients were randomised to have closure of laparoscopic port sites using either OCA or sutures. Patients were reviewed at 24 hours and returned for follow-up 1 week and 1 month after postoperatively. At these times, different wound characteristics were documented: Two tools were used to measure the cosmetic result using Hollander wound evaluation scale (HWES) and the patient and observer scar assessment scale (POSAS). A total of 70 patients, 35 in each group were enrolled. The wounds were closed significantly faster in the OCA group (mean 229.16 [±43.7] seconds versus 258.82 [±51.7] seconds, P = .01). Statistically significant difference in favour of using OCA was found for dehiscence (17.1% versus none in the suture group, P = .025) after 1 week. However, no difference was found for wound dehiscence after 1 month. OCA and suture groups did not differ significantly on patient satisfaction. There were no differences in the percentage of wounds achieving optimal scores on the HWES (suture 85.7% versus OCA 74.2%, P = .169). Nerveless, wound evolution was judged to be significantly better in the OCA group using POSAS. Patients' median POSAS was 9.45 (6-11) and 11.43 (10-13) in the OCA and suture groups, respectively (P = .005), and surgeon's median POSAS was 9.42 (6-11) and 11.48 (10-13) in the OCA and suture groups, respectively (P = .006). N-butyl-cyanoacrylate tissue adhesive is an acceptable technique for the closure of laparoscopic wounds with less operative time, and cosmetic results are comparable to suturing.
