Objective— To evaluate single and double layer end‐to‐end anastomosis in equine jejunum. Study Design— Experimental in vitro study. Animals— Mid‐jejunal sections from 12 adult horses without gastrointestinal disease. Methods— Jejunal end‐to‐end anastomoses were performed by a continuous Lembert pattern or a simple continuous pattern oversewn with a Cushing pattern. Jejunal segments were distended with fluid at 1 L/min, and intraluminal pressure at failure, and mode of failure were recorded. Bursting pressure and bursting wall tension were calculated. Anastomosis construction time and degree of luminal reduction were recorded. Results— Single layer anastomoses were constructed in less time than 2‐layer anastomoses. Both anastomotic techniques resulted in luminal reduction compared with control tissue; however, the reduction was smaller with a 1‐layer continuous Lembert anastomosis. No differences were noted in bursting pressure or bursting wall tension between groups. Conclusions— Anastomosis using a 1‐layer continuous Lembert pattern resulted in a larger stoma, was faster to perform, and as strong as a 2‐layer anastomosis. Clinical Relevance— Use of a 1‐layer continuous Lembert pattern for jejunojejunosotomy may be beneficial by decreasing anastomosis time and produce a larger stoma than a 2‐layer anastomosis.
