Ex Vivo Comparison of the Biomechanical Properties of Hand-Sewn and Stapled Jejunoileal Anastomoses in Horses

ObjectiveTo compare bursting strength, construction time, and anastomotic dimensions of 4 jejunoileal anastomotic techniques.Study DesignExperimental ex vivo study.AnimalsAdult horses (n=12).MethodsJejunoileal anastomoses were constructed from harvested ileal and distal jejunal segments using a single-layer Lembert technique (1HS), double-layer simple continuous/Cushing technique (2HS), stapled side-to-side technique (SS), or stapled functional end-to-end technique (FEE). Anastomotic construction time was recorded. Bursting pressures (BP), bursting wall tension (BWT), percentage of mean anastomotic luminal diameter reduction, percentage of luminal diameter reduction relative to adjacent ileal and jejunal diameters and stomal length, were calculated.ResultsFEE had the shortest construction time. BP of 1HS and 2HS was significantly higher than FEE and SS (P

目的 比较4种空肠回肠吻合技术的破裂强度、构建时间和吻合尺寸。 研究设计 体外实验研究。 动物 成年马（n = 12）。 方法 使用单层伦伯特技术（1HS）、双层单纯连续/库欣技术（2HS）、侧侧吻合器吻合技术（SS）或功能性端端吻合器吻合技术（FEE），由获取的回肠段和空肠远段构建空肠回肠吻合。记录吻合构建时间。计算破裂压力（BP）、破裂壁张力（BWT）、平均吻合管腔直径减少的百分比、相对于相邻回肠和空肠直径的管腔直径减少百分比以及吻合口长度。 结果 FEE的构建时间最短。1HS和2HS的BP显著高于FEE和SS（P
