Use of a rigid-type polyethylene T-cannula, silicone tubing, and adhesion netting for surgical cannulation of ileum of the horse.

This study explores the use of a rigid polyethylene T-cannula, silicone tubing, and adhesion netting for surgical operations on the ileum of horses, showing successful outcomes with the technique preventing dislodgment and leakage.

Objective and Methodology

• The primary objective of the study was to explore and improve upon existing techniques for ileal cannulation, a surgical process where a tube is inserted into the ileum—the final part of the small intestine.
• The researchers used a rigid polyethylene T-cannula, silicone tubing, and adhesion netting to perform the surgery on six horses. A T-cannula is a device with a T-shaped drainage tube often used in surgical procedures.
• To improve outcomes, they ensured the cannula was firmly adhered to the intestine and abdominal wall using a polyethylene net which promoted secure adhesion.
• The cannulated section of the intestines was then exteriorized through a controlled incision, located at the lateral ventral wall on the transverse line of the second lumber vertebra. The cannula was secured with a flange, a kind of projecting flat rim.

Results and Conclusion

• The research study successfully demonstrated an improved technique for ileal cannulation, with no leakage of digesta — the mixture of food and digestive enzymes present in the digestive system after the process of digestion.
• After undergoing this procedure, the horses were put on a special diet that gradually increased their concentrate intake and eliminated roughage. The researchers reported that this feeding regime successfully prevented any signs of colic – a severe, often fluctuating pain in the abdomen.
• The successful outcomes from the experiment suggest that this particular surgical technique using a rigid polyethylene T-cannula, silicone tubing, and adhesion netting can potentially be employed in operations involving the ileum of horses, and possibly other animals.
