Ex vivo comparison of barbed sutures for pelvic flexure enterotomy in horses.

Abstract: To evaluate two different barbed sutures for closure of pelvic flexure enterotomies and compare results achieved with two previously described closure techniques. Methods: Ex vivo. Methods: Twenty-four fresh cadaver adult equine large colons. Methods: Cadavers were randomly assigned to four closure groups (n = 6 each group): single-layer absorbable suture, double-layer absorbable suture, single-layer unidirectional barbed suture, or single-layer bidirectional barbed suture. Construction time, luminal reduction (percentage), bursting pressure, and method of failure were measured. Cost, leakage, exposed suture, and general appearance were recorded. Comparisons were performed with one-way analysis of variance and post hoc Bonferroni test (P < .05). Results: Double-layer absorbable closure had the highest bursting pressure (mean = 178.5 mm Hg, SD = 9.79, P  .06). Bursting strengths of both unidirectional (mean = 91.6 mm Hg, SD = 5.57) and bidirectional (mean = 87.5 mm Hg, SD = 8.69) barbed sutures were lower (P > .006 for both) than those of both single- (mean = 117.6 mm Hg, SD = 11.69) and double-layer (mean = 178.5 mm Hg, SD = 9.79) closures. Unidirectional barbed suture closure had a reduction in lumen diameter (P = .004) compared with bidirectional and single-layer closures. Conclusions: Enterotomy closures with the two different barbed suture patterns were comparable in bursting strength and construction time. However, the barbed suture patterns had lower bursting strength compared with traditional single- and double-layer closures. Unidirectional barbed suture closure also reduced lumen diameter. Conclusions: Closure of a large colon enterotomy with barbed suture patterns may be less secure than single- and double-layer suture closure.

The research compares two types of barbed sutures for closing enterotomies in horses, finding that while comparable to each other, they had lower bursting strength and reduced the diameter of the gut compared to traditional single-layer and double-layer sutures.

Study Design and Methodology

  • The study was executed on 24 fresh adult horse large colon cadavers, divided into four groups of six, each undergoing different closure techniques: single-layer absorbable suture, double-layer absorbable suture, single-layer unidirectional barbed suture, and single-layer bidirectional barbed suture.
  • Various parameters such as the time taken for construction, luminal reduction, bursting pressure, method of failure, cost, leakage, exposed suture, and general appearance were monitored.
  • Statistical analysis was conducted using one-way analysis of variance and post hoc Bonferroni test to compare the results derived from the four groups.

Key Findings

  • The double-layer absorbable closure had the highest bursting pressure, implying the highest resistance to rupture, but required a longer time to execute compared to all other groups.
  • Both types of barbed suture closures took similar construction time to the single-layer closure, pointing to their comparative efficiency in time management.
  • However, both unidirectional and bidirectional barbed sutures had lower bursting strengths than the single-layer and double-layer closures, indicating they were less resistant to rupture.
  • Unidirectional barbed suture closure resulted in a reduction in the diameter of the lumen compared with bidirectional and single-layer closures, suggesting a potential impact on the intestinal passage.

Conclusions

  • The two different barbed suture patterns displayed comparable bursting strength and construction time,
  • Yet, compared to traditional closures, the barbed suture patterns, whether unidirectional or bidirectional, were less effective as they showed lower bursting strength and contributed to the reduction of lumen diameter.
  • These results suggest that using these barbed suture patterns for closure of a large colon enterotomy in horses might be less secure and potentially problematic when compared with single-and double-layer suture closure. The reduced resistance to rupture and the diminished size of the intestinal passage could lead to complications in the healing process after surgery.
