A Comparison of the Mechanical Strength of Two Stapled Anastomosis Techniques for Equine Small Intestine

Abstract

The FEE is a clinically viable technique.

Evaluation of a laparoscopic technique for collection of serial full-thickness small intestinal biopsy specimens in standing sedated horses

“…22 Use of stapling devices has become more prevalent in equine abdominal surgery because of the reduction in surgery time and minimized risk of abdominal contamination that are possible when the instruments are used appropriately. 22 Use of stapling devices has become more prevalent in equine abdominal surgery because of the reduction in surgery time and minimized risk of abdominal contamination that are possible when the instruments are used appropriately.…”

“…Even when the technique is limited to use by surgeons with advanced laparoscopic training, an associated risk of complications remains. Bickers et al 22 reported stapled functional end-to-end jejunojejunostomy segments to consistently fail at the crotch of the V where the 2 intestinal segments merged. In humans, use of endoscopic staplers for obtaining laparoscopic fullthickness biopsy specimens is safe and effective.…”

“…Endoscopic stapling devices have gained widespread clinical use. 22 The junction of the crossed staple line may warrant further investigation to determine whether this region is the weakest point of the constructed intestinal biopsy site. 12,13 Intestinal biopsy specimens are collected by applying traction on the antimesenteric border of the small intestine with a laparoscopic forceps and firing the ELS across the tented antimesenteric border of the intestine.…”

“…[22][23][24] Biomechanical testing of the collected intestinal segments was performed within 3 hours after collection. Duodenal segments were collected from a point 5 cm aboral to the duodenal sigmoid flexure to the most aboral portion of the ascending duodenum.…”

“…22,25 Bursting wall tension in dynes per centimenter was calculated by use of LaPlace' s law: BWT = BP X r, where BWT is bursting wall tension, BP is bursting pressure, and r is radius. Air in the tested intestine segment was removed through the end cap and bleeder screw.…”
