title: Comparison of single layer staple closure versus double layer hand-sewn closure for equine pelvic flexure enterotomy.
abstract: Our objective was to compare thoracoabdominal (TA Premium™ 90) stapled enterotomy closure to traditional hand-sewn closure, using time to perform the technique, luminal diameter, and bursting pressure in ex-vivo specimens. The pelvic flexures of 13 client-owned horses were harvested. Each pelvic flexure had 1 enterotomy performed; 6 were closed via staples, 7 closures were hand-sewn. Luminal diameter at the enterotomy site was assessed via contrast radiography performed pre-and post-enterotomy. Bursting pressure of the closure was assessed by continuous manometry during rapid infusion. Time to perform stapled closure was significantly shorter than hand-sewn closure (P < 0.0001). Percent reduction of luminal diameters was significantly decreased in stapled specimens (P = 0.034). There was no significant difference in bursting strength between closure techniques (P = 0.196). In conclusion, stapled enterotomy closure offers statistically significant reduction in closure time and better maintains pre-enterotomy luminal diameter without reducing biomechanical strength, compared to a double layer hand-sewn closure.
