A Novel Surgical Methodology for Dual Cannula Placement of the Ileum and Cecum in Equids: Assessment of Postoperative Management and Clinical Outcome.

This research study explored a new surgical method for placing two cannulas in specific parts of a horse’s digestive tract, namely the ileum and cecum, assessing the postoperative care and complications, and resulting in a survival rate of 63% among the 8 tested ponies.

Objective and Motivation

• The study aimed to develop a new surgical method for dual cannula placement in both the ileum and cecum parts of the equine digestive tract. The motivation behind this was to expand on current knowledge and research surrounding equine digestibility and gastrointestinal physiology, which has tended to focus on isolated sections of the digestive tract.

Methodology and Procedure

• In this study, a total of 8 ponies underwent surgical procedures for the dual placement of cannulae in the ileum and cecum. The researchers also developed a defined preoperative and postoperative procedure to monitor and manage the animals. They documented the process of managing any complications that arose post-surgery.

Postoperative Results and Complications

• All the ponies awoke and stood up after the surgery, which indicates an initial successful recovery from the procedure. However, in the course of postoperative care, various complications became apparent. These included increased body temperature (indicative of potential infection), dehydration (possibly due to a lack of food and water during recovery), lameness, and abdominal issues such as herniation (the protrusion of an organ through the wall that contains it) and peritonitis (inflammation of the peritoneum, the lining of the inner wall of the abdomen).

Survival Rates and Further Implications

• The research found that 63% of the ponies survived after the dual cannulation procedure, with the main cause of fatality being intestinal herniation. This provides a crucial survival rate statistic for this novel surgical method, highlighting the risks and potential areas of complication for future procedures.
• The researchers posit that the information yielded from this study could help the academic and veterinary community to better plan and implement dual cannulation procedures in horses. The ultimate aim would be to mitigate against postoperative complications and improve survival rates, whilst also expanding our understanding of equine gastrointestinal function.
