Abstract / Description of output

Skin closure of laparotomy incisions using topical 2-octyl cyanoacrylate (2-OCA) mesh provides a secure bactericidal barrier in humans, which may reduce the risk of postoperative incisional complications. However, the benefits of using this mesh have not been objectively assessed in horses.
From 2009 to 2020, three methods of skin closure were used following laparotomy for acute colic, including metallic staples (MS), suture (ST) and cyanoacrylate mesh (DP). The closure method was not randomised. Owners were contacted 3 months or more after the surgery to record any postoperative complications that occurred. For each method of closure, the rates of surgical site infection (SSI) and herniation were recorded, as well as surgical time and treatment costs, including those for incisional complications. Chi-square testing and logistic regression modelling were used to assess differences between the groups.
A total of 110 horses were recruited (45 in the DP group, 49 in the MS group and 16 in the ST group) The overall rate of SSI was 15.5%, with rates of 8.9%, 18.4% and 25% for the DP, MS and ST groups, respectively (p = 0.23). In addition, incisional hernias developed in 21.8% of cases, with 8.9%, 34.7% and 18.8% of horses in the DP, MS and ST groups, respectively, being affected (p = 0.009). The median total treatment cost did not differ significantly between groups (p = 0.47).
This was a retrospective study with non-randomised choice of closure method.
No significant differences in the rate of SSI or overall cost wwere demonstrated between treatment groups. However, MS was associated with a higher rate of hernia formation than DP or ST. Despite increased capital cost, 2-OCA proved to be a safe skin closure method in horses and was no more expensive than DP or ST by the time visits to remove sutures/staples and treat infections were factored in.
