Ex vivo and in vivo evaluation of a modified interrupted Lembert pattern for small intestinal anastomoses in horses

Objective To compare single‐layer anastomoses (modified continuous Lembert [mod‐CL] and modified‐interrupted Lembert [mod‐IL]) and a 2‐layer simple continuous anastomosis (2 L; seromuscular and mucosal) for jejunojejunal anastomoses in equine cadavers and to compare ex vivo to in vivo time to complete the anastomosis and stoma size with a mod‐IL pattern. Study design Measurements in jejunum from cadaver and anesthetized horses. Animals Ten live horses and 18 equine cadavers. Methods Time to complete anastomosis, bursting pressures (BP), leakage sites, and anastomotic index (size ratio of anastomotic lumen to control lumen) were recorded. Time to completion and lumen size were compared between in vivo and ex vivo mod‐IL patterns. Results The mod‐CL pattern was fastest (8.44 ± 1.30 min, p
