In vitro evaluation of an inverted end-to-end equine jejunojejunal anastomosis using skin staples.
Abstract: To compare functional indices of end-to-end (EEA) jejunojejunal anastomosis using skin staples in horses with a 2-layer inverting hand-sewn technique. Methods: Experimental study. Methods: Jejunal segments from 8 fresh equine cadavers. Methods: For each bowel segment, 2 EEA anastomoses were created: one 2-layer hand-sewn and one 1-layer using skin staples. Time for anastomosis creation was recorded and compared. Lumen diameter of each anastomosis was measured on digital radiographs after intraluminal instillation of contrast medium and inflation of the jejunal segments to 14 mm Hg. Anastomotic indices (a compensated measure of stoma diameter) and bursting pressure were determined. Results: EEA jejunal anastomosis using skin staples was significantly faster than use of a 2-layer hand-sewn technique. Anastomotic index, a measure of lumen size, was significantly larger with the skin-staple technique; however, the bursting pressure of stapled anastomoses was significantly less than for the hand-sewn technique, but the values were well above those reported for other anastomotic techniques. Conclusions: An anastomotic technique using skin staples was easy to learn and perform, effective and faster, and mechanically comparable with a hand-sewn 2-layer technique. Conclusions: The staple technique could be beneficial in equine gastrointestinal surgery by reducing anastomosis time, although further in vivo studies are needed to establish clinical safety.

This study primarily investigates the effectiveness of using skin staples for performing end-to-end anastomosis procedures on horses’ jejunal segments compared to the traditional 2-layer hand-sewn technique. Findings reveal that although the stapler technique is significantly faster and easier to learn, future in vivo studies are required to establish its clinical safety.
Methods
- The study involved the jejunal segments extracted from eight fresh equine cadavers.
- Researchers performed two end-to-end anastomosis on each bowel segment – one using a one-layer skin stapler technique and the other using a two-layer hand-sewn technique.
- They compared the time taken to create an anastomosis with both techniques. In addition, the researchers also measured and compared the lumen diameter of each anastomosis. This data was collected using digital radiographs taken after they instilled contrast medium into the lumens and inflated them to a constant level of 14mm Hg.
Findings
- The results indicated that creating an end-to-end jejunal anastomosis using skin staples was significantly faster than utilizing a two-layer hand-sewn technique.
- The anastomotic index, the measure of lumen size, was calculated to be larger in the skin-staple technique. However, the bursting pressure of stapled anastomoses was found to be significantly less than that of the hand-sewn ones. Despite this, the bursting pressure of the stapler technique remained superior to those previously reported values for other anastomosis techniques.
Conclusions
- The skin staple technique proved to be easy to learn, effective, faster, and mechanically comparable to the traditional hand-sewn technique.
- Considering that this technique reduces the anastomosis time, it could potentially be beneficial in equine gastrointestinal surgery. However, as the researchers highlight, there is a need for more in vivo studies to verify its clinical safety and applicability.
