In Vitro Comparison of a Single‐Layer (Continuous Lembert) versus Two‐Layer (Simple Continuous/Cushing) Hand‐Sewn End‐to‐End Jejunoileal Anastomosis in Normal Equine Small Intestine
To compare in vitro physical and mechanical characteristics of 1‐layer and 2‐layer end‐to‐end jejunoileostomy.
In vitro experimental study.
Adult horses (n = 6).
Harvested equine jejunum and ileum was used to create 1‐ and 2‐layer end‐to‐end jejunoileostomy specimens. Construction time, bursting pressure, and relative lumen diameter (anastomosis diameter expressed as a percentage of the lumen diameter of adjacent jejunum and ileum) were compared. Construction time and relative lumen diameters were compared using a paired t‐test. Bursting pressure for anastomoses and control jejunal segments were compared using a repeated‐measure ANOVA. Statistical significance was set at P < .05.
Mean (±SEM) construct completion times were shorter for 1 layer (21 ± 0.91 minutes) than 2 layers (26.71±1.16 minutes; P = .005). Relative lumen diameters (percentage of jejunal diameter) were larger for 1 layer (77.67 ± 4.46%) than for 2 layers (69.37 ± 2.8%; P = .035). There were no significant differences in bursting pressures between the 2 groups and the control jejunum (P =.155) or relative lumen diameters (percentage of ileal diameter; P =.118).
One‐layer jejunoileostomy can be created in a shorter time and maintain a larger anastomosis luminal diameter without compromising maximum bursting pressure when compared to 2‐layer jejunoileostomy.
