Initial evaluation of a technique for complete cecal bypass in the horse.

This research paper presents a new surgical method for complete bypass of the cecum in horses, without necessitating ileal transection. The study involves an experimental procedure performed on four adult horses, suggesting that the technique is technically simple, efficient, and potentially less risky compared to traditional methods.

Methodology

• The procedure was performed on four adult horses for experimental purposes.
• Through a ventral median celiotomy, a special surgical procedure that involves incision and exposure of the abdominal cavity, a jejunocolostomy was performed using an intraluminal anastomosis device (ILA-100).
• The surgical stitch line was reinforced with a Cushing pattern to strengthen the staple line.
• Four rows of staples were then used to close off the lumen of the distal jejunum and proximal ileum, immediately after the anastomosis using a thoracoabdominal stapling device (TA-90).
• Necropsy exams, post-mortem examinations used to determine the cause of death or further understand disease processes, were carried out at least 60 days after surgery.

Results

• There were no complications during the operations.
• The cecal bypass was found to be functional in all the horses at necropsy.
• In one horse, the most oral staple line across the ileum partially failed, but the cecal bypass was still functional.

Conclusions

• The research proposes that complete cecal bypass without ileal transection is a workable alternative to the traditional methods of performing a complete cecal bypass.
• It’s recommended that two sets of staple lines across the ileum be used.
• The new method is technically simpler to execute and may reduce time and risk of contamination as compared to complete cecal bypass with ileal transection.
• It was concluded that longer term follow-up is necessary before the technique may be used clinically.
