OBJECTIVE: To compare the in vitro biomechanical properties of a novel subcuticular stapling device to current methods of abdominal skin closure for equine abdominal surgery.

STUDY DESIGN: In vitro randomized, matched design.

SAMPLE POPULATION: Equine ventral median abdominal skin specimens (n = 24 horses).

METHODS: Subcuticular absorbable staples (SAS), metallic staples (MS), polyglyconate suture (PG), and nylon monofilament (NYL) were applied to longitudinally transected portions of equine ventral midline skin. Loads that resulted in an initial failure point and the ultimate failure load and mechanism were recorded.

RESULTS: Mean ± SD loads at initial failure for PG (86 N ± 64 N), NYL (81 N ± 142 N), and SAS (70 N ± 20 N) were not significantly different from each other. PG and SAS were significantly higher than MS (43 N ± 17 N; P 
CONCLUSIONS: SAS had the lowest ultimate failure load; however, other measured variables identified characteristics of SAS that may be clinically beneficial.
